When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.
At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.
So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.
The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

From the FILES section of the git-config(1) manual:

If a commit object has a header line at the end of the
buffer that is missing its newline (or if it appears so
because the content on the header line contains a stray
NUL), then git will segfault.
Interestingly, this case is explicitly handled and we do
correctly scan the final line for the header we are looking
for. But if we don't find it, we will dereference NULL while
trying to look at the next line.
Git will never generate such a commit, but it's good to be
defensive. We could die() in such a case, but since it's
easy enough to handle it gracefully, let's just issue a
warning and continue (so you could still view such a commit
with "git show", though you might be missing headers after
the NUL).

When we parse the name and email from a commit to
pretty-print them, we usually can just put the result
directly into our strbuf result. However, if we are going to
use the mailmap, then we must first copy them into a
NUL-terminated buffer to feed to the mailmap machinery.
We did so by using strlcpy into a static buffer, but we used
it wrong. We fed it the length of the substring we wanted to
copy, but never checked that that length was less than the
size of the destination buffer.
The simplest fix is to just use snprintf to copy the
substring properly while still respecting the destination
buffer's size. It might seem like replacing the static
buffer with a strbuf would help, but we need to feed a
static buffer to the mailmap machinery anyway, so there's
not much benefit to handling arbitrary sizes.
A more ideal solution would be for mailmap to grow an
interface that:
1. Takes a pointer and length combination, instead of
assuming a NUL-terminated string.
2. Returns a pointer to the mailmap's allocated string,
rather than copying it into the buffer.
Then we could avoid the need for an extra buffer entirely.
However, doing this would involve a lot of refactoring of
mailmap and of string_list (which mailmap uses to store the
map itself). For now, let's do the simplest thing to fix the
bug.

Commit 875b91b (diff --no-index: use strbuf for temporary pathnames,

from heap-allocated char arrays caused paths to form like 'dir/file1',

When we are showing reflog selectors during a walk, we infer
from context whether the user wanted to see the index in
each selector, or the reflog date. The current rules are:
1. if the user asked for an explicit date format in the
output, show the date
2. if the user asked for ref@{now}, show the date
3. if neither is true, show the index
However, if we see "ref@{0}", that should be a strong clue
that the user wants to see the counted version. In fact, it
should be much stronger than the date format in (1). The
user may have been setting the date format to use in another
part of the output (e.g., in --format="%gd (%ad)", they may
have wanted to influence the author date).
This patch flips the rules to:
1. if the user asked for ref@{0}, always show the index
2. if the user asked for ref@{now}, always show the date
3. otherwise, we have just "ref"; show them counted by
default, but respect the presence of "--date" as a clue

When we prepare to walk a reflog, we parse the specification
and pull some information from it, such as which reflog to
look in (e.g., HEAD), and where to start (e.g., HEAD@{10} or
HEAD@{yesterday}). The resulting struct has a "recno" field
to show where in the reflog we are starting. It also has a
"flag" field; if true, it means the recno field came from
parsing a date like HEAD@{yesterday}.
There are two problems with this:
1. "flag" is an absolutely terrible name, as it conveys
nothing about the meaning
2. you can tell "HEAD" from "HEAD@{yesterday}", but you
can't differentiate "HEAD" from "HEAD{0}"

introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.
Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.
This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

We already check that @{now} and "--date" cause the
displayed selector to use the date for both the multiline
and oneline formats. However, we miss several cases:
1. The --format=%gd selector is not tested at all.
2. We do not check how the log.date config interacts with the
"--date" magic (according to f4ea32f, it should not
impact the output).
Doing so reveals that the combination of both (log.date
combined with the %gd format) does not behave as expected.

Previously, we tested only that "push --quiet --no-progress"
was silent. However, there are many other combinations that
were not tested:
1. no options at all (but stderr as a tty)
2. --no-progress by itself
3. --quiet by itself
4. --progress (when stderr not a tty)
These are tested elsewhere for general "push", but it is
important to test them separately for http. It follows a
very different code path than git://, and options must be
relayed across a remote helper to a separate send-pack
process (and in fact cases (1), (2), and (4) have all been
broken just for http at some point in the past).
We can drop the "--quiet --no-progress" test, as it is not
really interesting (it is already handled by testing them
separately in (2) and (3) above).

The send_pack function gets a "progress" flag saying "yes,
definitely show progress" or "no, definitely do not show
progress". This gets set properly by transport_push when
send_pack is called directly.
However, when the send-pack command is executed separately
(as it is for the remote-curl helper), there is no way to
tell it "definitely do this". As a result, we do not
properly respect "git push --no-progress" for smart-http
remotes; you will still get progress if stderr is a tty.
This patch teaches send-pack --progress and --no-progress,
and teaches remote-curl to pass the appropriate option to
override send-pack's isatty check. This fixes the
--no-progress case above, and as a bonus, also makes "git
push --progress" work when stderr is not a tty.

The send_pack_args struct has two verbosity flags: "quiet"
and "progress". Originally, if "quiet" was set, we would
tell pack-objects explicitly to be quiet, and if "progress"
was set, we would tell it to show progress. Otherwise, we
told it neither, and it relied on isatty(2) to make the
decision itself.
However, commit 01fdc21 changed the meaning of these
variables. Now both "quiet" and "!progress" instruct us to
tell pack-objects to be quiet (and a non-zero "progress"
means the same as before). This works well for transports
which call send_pack directly, as the transport code copies
transport->progress into send_pack_args->progress, and they
both have the same meaning.
However, the code path of calling "git send-pack" was left
behind. It always sets "progress" to 0, and thus always
tells pack-objects to be quiet. We can work around this by
checking isatty(2) ourselves in the cmd_send_pack code path,
restoring the original behavior of the send-pack command.

The shell function that starts git-daemon wants to read the first line of
the daemon's stderr to ensure that it started correctly. Subsequent daemon
errors should be redirected to fd 4 (which is the terminal in verbose mode
or /dev/null in quiet mode). To that end the shell script used 'read' to
get the first line of output, and then 'cat &' to forward everything else
in a background process.
The problem is, that 'cat >&4 &' does not produce any output because the
shell redirects a background process's stdin to /dev/null. To have this
command invocation do anything useful, we have to redirect its stdin
explicitly (which overrides the /dev/null redirection).
The shell function connects the daemon's stderr to its consumers via a
FIFO. We cannot just do this:
read line <git_daemon_output
cat <git_daemon_output >&4 &
because after the first redirection the pipe is closed and the daemon
could receive SIGPIPE if it writes at the wrong moment. Therefore, we open
the readable end of the FIFO only once on fd 7 in the shell and dup from
there to the stdin of the two consumers.

In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

Test "pushing to local repo" in t5800-remote-helpers can hang
due to a race condition in git-remote-testgit. Fix it by
setting stdin to unbuffered.
On the writer side, "git push" invokes push_refs_with_export(),
which sends to stdout the command "export\n" and immediately
starts up "git fast-export". The latter writes its output stream
to the same stdout.
On the reader side, remote helper "git-remote-testgit" reads from
stdin to get its next command. It uses getc() to read characters
from libc up until \n. Libc has buffered a potentially much
larger chunk of stdin. When it sees the "export\n" command, it
forks "git fast-import" to read the stream.
If fast-export finishes before git fast-import starts, the
fast-export output can end up in libc's buffer in
git-remote-testgit, rather than in git fast-import. The latter
hangs indefinitely on a now-empty stdin.

git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.
As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.
This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:
1. We can drop the custom append function (which,
incidentally, had an off-by-one error exacerbating the
static limit).
2. We can drop the ugly magic numbers used when adding
arguments to "prune".
3. Adding further arguments will be easier; you can just
add new "push" calls without worrying about increasing
any static limits.

An empty argv-array is initialized to point to a static
empty NULL-terminated array. The original implementation
separates the actual storage of the NULL-terminator from the
pointer to the list. This makes the exposed type a "const
char **", which nicely matches the type stored by the
argv-array.
However, this indirection means that one cannot use
empty_argv to initialize a static variable, since it is
not a constant.
Instead, we can expose empty_argv directly, as an array of
pointers. The only place we use it is in the ARGV_ARRAY_INIT
initializer, and it decays to a pointer appropriately there.

Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.
Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.
Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.
In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.
Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.

Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.
Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.
Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

We give the username and password to curl by sticking them
in a buffer of the form "user:pass" and handing the result
to CURLOPT_USERPWD. Since curl 7.19.1, there is a split
mechanism, where you can specify each element individually.
This has the advantage that a username can contain a ":"
character. It also is less code for us, since we can hand
our strings over to curl directly. And since curl 7.17.0 and
higher promise to copy the strings for us, we we don't even
have to worry about memory ownership issues.
Unfortunately, we have to keep the ugly code for old curl
around, but as it is now nicely #if'd out, we can easily get
rid of it when we decide that 7.19.1 is "old enough".

When we have a credential to give to curl, we must copy it
into a "user:pass" buffer and then hand the buffer to curl.
Old versions of curl did not copy the buffer, and we were
expected to keep it valid. Newer versions of curl will copy
the buffer.
Our solution was to use a strbuf and detach it, giving
ownership of the resulting buffer to curl. However, this
meant that we were leaking the buffer on newer versions of
curl, since curl was just copying it and throwing away the
string we passed. Furthermore, when we replaced a
credential (e.g., because our original one was rejected), we
were also leaking on both old and new versions of curl.
This got even worse in the last patch, which started
replacing the credential (and thus leaking) on every http
request.
Instead, let's use a static buffer to make the ownership
more clear and less leaky. We already keep a static "struct
credential", so we are only handling a single credential at
a time, anyway.

When we pack everything into one big pack with "git repack
-Ad", any unreferenced objects in to-be-deleted packs are
exploded into loose objects, with the intent that they will
be examined and possibly cleaned up by the next run of "git
prune".
Since the exploded objects will receive the mtime of the
pack from which they come, if the source pack is old, those
loose objects will end up pruned immediately. In that case,
it is much more efficient to skip the exploding step
entirely for these objects.
This patch teaches pack-objects to receive the expiration
information and avoid writing these objects out. It also
teaches "git gc" to pass the value of gc.pruneexpire to
repack (which in turn learns to pass it along to
pack-objects) so that this optimization happens
automatically during "git gc" and "git gc --auto".

This is main test case for the original problem that triggered this
patch series. We create a repo with 50k tags and then test whether
git-clone over the smart HTTP protocol succeeds.
Note that we construct the repo in a slightly different way than the
original script used to reproduce the problem. This is because the
original script just created 50k tags all pointing to the same commit,
so if there was a bug where remote-curl.c was not passing all the refs
to fetch-pack we wouldn't know. The clone would succeed even if only one
tag was passed, because all the other tags were pointing at the same SHA
and would be considered present.
Instead we create a repo with 50k independent (dangling) commits and
then tag each of those commits with a unique tag. This way if one of the
tags is not given to fetch-pack, later stages of the clone would
complain about it.
This allows us to test both that the command line overflow was fixed, as
well as that it was fixed in a way that doesn't leave out any of the
refs.

The syntax for the use of mark references in fast-import
demands either a SP (space) or LF (end-of-line) after
a mark reference. Fast-import does not complain when garbage
appears after a mark reference in some cases.
Factor out parsing of mark references and complain if
errant characters are found. Also be a little more careful
when parsing "inline" and SHA1s, complaining if extra
characters appear or if the form of the dataref is unrecognized.
Buggy input can cause fast-import to produce the wrong output,
silently, without error. This makes it difficult to track
down buggy generators of fast-import streams. An example is
seen in the last line of this commit command:
commit refs/heads/S2
committer Name <name@example.com> 1112912893 -0400
data <<COMMIT
commit message
COMMIT
from :1M 100644 :103 hello.c
It is missing a newline and should be:
[...]
from :1
M 100644 :103 hello.c
What fast-import does is to produce a commit with the same
contents for hello.c as in refs/heads/S2^. What the buggy
program was expecting was the contents of blob :103. While
the resulting commit graph looked correct, the contents in
some commits were wrong.

When git-rebase--interactive stops due to a conflict and the only change
to be committed is in a submodule, the test for whether there is
anything to be committed ignores the staged submodule change. This
leads rebase to skip creating the commit for the change.
While unstaged submodule changes should be ignored to avoid needing to
update submodules during a rebase, it is safe to remove the
--ignore-submodules option to diff-index because --cached ensures that
it is only checking the index. This was discussed in [1] and a test is

The sed provided by Solaris in /usr/xpg4/bin has a bug whereby an
unanchored regex using * for zero or more repetitions sees two
separate matches fed to the substitution engine in some cases.
This is evidenced by:
$ for sed in /usr/xpg4/bin/sed /usr/bin/sed /opt/csw/gnu/sed; do \
echo 'ab' | $sed -e 's|[a]*|X|g'; \
done
XXbX
XbX
XbX
This bug was triggered during a git submodule clone operation as
exercised in the setup stage of t5526-fetch-submodules when using the
default SANE_TOOL_PATH for Solaris. It led to paths such as
..../.. being used in the submodule .git gitdir reference.
Using the expression 's|\([^/]*\(/*\)\)|..\2|g' provides the desired
result with all three three tested sed implementations but is harder
to read. As we do not need to handle fully qualified paths though,
the expression could actually be [^/]+ which isn't properly handled
either. Instead, use [^/][^/]*, as suggested by Andreas Schwab, which
works on all three tested sed implementations.
The new expression is semantically different than the original one.
It will not place a leading '..' on a fully qualified path as the
original expression did. All of the paths being passed through this
regex are relative and did not rely on this behaviour so it's a safe
change.

When execvp reports EACCES, it can be one of two things:
1. We found a file to execute, but did not have
permissions to do so.
2. We did not have permissions to look in some directory
in the $PATH.
In the former case, we want to consider this a
permissions problem and report it to the user as such (since
getting this for something like "git foo" is likely a
configuration error).
In the latter case, there is a good chance that the
inaccessible directory does not contain anything of
interest. Reporting "permission denied" is confusing to the
user (and prevents our usual "did you mean...?" lookup). It
also prevents git from trying alias lookup, since we do so
only when an external command does not exist (not when it
exists but has an error).
This patch detects EACCES from execvp, checks whether we are
in case (2), and if so converts errno to ENOENT. This
behavior matches that of "bash" (but not of simpler shells
that use execvp more directly, like "dash").

The POSIX standard specifies a return type of int for all six exec
functions. In addition, all exec functions return -1 on error, and
simply do not return on success. However, the current emulation of
the exec functions on mingw are declared with a void return type.
This would cause a problem should any code attempt to call the
exec function in a non-void context. In particular, if an exec
function were used in a conditional it would fail to compile.
In order to improve the fidelity of the emulation, we change the

The user can say "git push" without specifying any refspec. When using
the "upstream" semantics via the push.default configuration, the user
wants to update the "upstream" branch of the current branch, which is the
branch at a remote repository the current branch is set to integrate with,
with this command.
However, there are cases that such a "git push" that uses the "upstream"
semantics does not make sense:
- The current branch does not have branch.$name.remote configured. By
definition, "git push" that does not name where to push to will not
know where to push to. The user may explicitly say "git push $there",
but again, by definition, no branch at repository $there is set to
integrate with the current branch in this case and we wouldn't know
which remote branch to update.
- The current branch does have branch.$name.remote configured, but it
does not specify branch.$name.merge that names what branch at the
remote this branch integrates with. "git push" knows where to push in
this case (or the user may explicitly say "git push $remote" to tell us
where to push), but we do not know which remote branch to update.
- The current branch does have its remote and upstream branch configured,
but the user said "git push $there", where $there is not the remote
named by "branch.$name.remote". By definition, no branch at repository
$there is set to integrate with the current branch in this case, and
this push is not meant to update any branch at the remote repository
$there.
The first two cases were already checked correctly, but the third case was
not checked and we ended up updating the branch named branch.$name.merge
at repository $there, which was totally bogus.

When "add -p" sees an unmerged entry, it shows the combined
diff and then immediately skips the hunk. This can be
confusing in a variety of ways, depending on whether there
are other changes to stage (in which case you get the
superfluous combined diff output in between other hunks) or
not (in which case you get the combined diff and the program
exits immediately, rather than seeing "No changes").
The current behavior was not planned, and is just what the
implementation happens to do. Instead, let's explicitly
remove unmerged entries from our list of modified files, and
print a warning that we are ignoring them.
We can cheaply find which entries are unmerged by adding
"--raw" output to the "diff-files --numstat" we already run.
There is one non-obvious thing we must change when parsing
this combined output. Before this patch, when we saw a
numstat line for a file that did not have index changes, we
would create a new record with 'unchanged' in the 'INDEX'
field. Because "--raw" comes before "--numstat", we must
move this special-case down to the raw-line case (and it is
sufficient to move it rather than handle it in both places,
since any file which has a --numstat will also have a --raw
entry).

If a remote repo has too many tags (or branches), cloning it over the
smart HTTP transport can fail because remote-curl.c puts all the refs
from the remote repo on the fetch-pack command line. This can make the
command line longer than the global OS command line limit, causing
fetch-pack to fail.
This is especially a problem on Windows where the command line limit is
orders of magnitude shorter than Linux. There are already real repos out
there that msysGit cannot clone over smart HTTP due to this problem.
Here is an easy way to trigger this problem:
git init too-many-refs
cd too-many-refs
echo bla > bla.txt
git add .
git commit -m test
sha=$(git rev-parse HEAD)
tag=$(perl -e 'print "bla" x 30')
for i in `seq 50000`; do
echo $sha refs/tags/$tag-$i >> .git/packed-refs
done
Then share this repo over the smart HTTP protocol and try cloning it:
$ git clone http://localhost/.../too-many-refs/.git
Cloning into 'too-many-refs'...
fatal: cannot exec 'fetch-pack': Argument list too long
50k tags is obviously an absurd number, but it is required to
demonstrate the problem on Linux because it has a much more generous
command line limit. On Windows the clone fails with as little as 500
tags in the above loop, which is getting uncomfortably close to the
number of tags you might see in real long lived repos.
This is not just theoretical, msysGit is already failing to clone our
company repo due to this. It's a large repo converted from CVS, nearly
10 years of history.
Four possible solutions were discussed on the Git mailing list (in no
particular order):
1) Call fetch-pack multiple times with smaller batches of refs.
This was dismissed as inefficient and inelegant.
2) Add option --refs-fd=$n to pass a an fd from where to read the refs.
This was rejected because inheriting descriptors other than
stdin/stdout/stderr through exec() is apparently problematic on Windows,
plus it would require changes to the run-command API to open extra
pipes.
3) Add option --refs-from=$tmpfile to pass the refs using a temp file.
This was not favored because of the temp file requirement.
4) Add option --stdin to pass the refs on stdin, one per line.
In the end this option was chosen as the most efficient and most
desirable from scripting perspective.
There was however a small complication when using stdin to pass refs to
fetch-pack. The --stateless-rpc option to fetch-pack also uses stdin for
communication with the remote server.
If we are going to sneak refs on stdin line by line, it would have to be
done very carefully in the presence of --stateless-rpc, because when
reading refs line by line we might read ahead too much data into our
buffer and eat some of the remote protocol data which is also coming on
stdin.
One way to solve this would be to refactor get_remote_heads() in
fetch-pack.c to accept a residual buffer from our stdin line parsing
above, but this function is used in several places so other callers
would be burdened by this residual buffer interface even when most of
them don't need it.
In the end we settled on the following solution:
If --stdin is specified without --stateless-rpc, fetch-pack would read
the refs from stdin one per line, in a script friendly format.
However if --stdin is specified together with --stateless-rpc,
fetch-pack would read the refs from stdin in packetized format
(pkt-line) with a flush packet terminating the list of refs. This way we
can read the exact number of bytes that we need from stdin, and then
get_remote_heads() can continue reading from the same fd without losing
a single byte of remote protocol data.
This way the --stdin option only loses generality and scriptability when
used together with --stateless-rpc, which is not easily scriptable
anyway because it also uses pkt-line when talking to the remote server.

The http-backend program sets default GIT_COMMITTER_NAME and
GIT_COMMITTER_EMAIL variables based on the REMOTE_USER and
REMOTE_ADDR variables provided by the webserver. However, it
unconditionally overwrites any existing GIT_COMMITTER
variables, which may have been customized by site-specific
code in the webserver (or in a script wrapping http-backend).
Let's leave those variables intact if they already exist,
assuming that any such configuration was intentional. There
is a slight chance of a regression if somebody has set
GIT_COMMITTER_* for the entire webserver, not intending it
to leak through http-backend. We could protect against this
by passing the information in alternate variables. However,
it seems unlikely that anyone will care about that
regression, and there is value in the simplicity of using
the common variable names that are used elsewhere in git.
While we're tweaking the environment-handling in
http-backend, let's switch it to use argv_array to handle
the list of variables. That makes the memory management much
simpler.

Each ref structure contains a "nonfastforward" field which
is set during push to show whether the ref rewound history.
Originally this was a single bit, but it was changed in
f25950f (push: Provide situational hints for non-fast-forward
errors) to an enum differentiating a non-ff of the current
branch versus another branch.
However, we never actually set the member according to the
enum values, nor did we ever read it expecting anything but
a boolean value. But we did use the side effect of declaring
the enum constants to store those values in a totally
different integer variable. The code as-is isn't buggy, but
the enum declaration inside "struct ref" is somewhat
misleading.
Let's convert nonfastforward back into a single bit, and
then define the NON_FF_* constants closer to where they
would be used (they are returned via the "int *nonfastforward"
parameter to transport_push, so we can define them there).

Merge-recursive detects renames so that if one side modifies
"foo" and the other side moves it to "bar", the modification
is applied to "bar". However, our rename detection is based
on content analysis, it can be wrong (i.e., two files were
not intended as a rename, but just happen to have the same
or similar content).
This is quite rare if the files actually contain content,
since two unrelated files are unlikely to have exactly the
same content. However, empty files present a problem, in
that there is nothing to analyze. An uninteresting
placeholder file with zero bytes may or may not be related
to a placeholder file with another name.
The result is that adding content to an empty file may cause
confusion if the other side of a merge removed it; your
content may end up in another random placeholder file that
was added.
Let's err on the side of caution and not consider empty
files as renames. This will cause a modify/delete conflict
on the merge, which will let the user sort it out
themselves.

Our rename detection is a heuristic, matching pairs of
removed and added files with similar or identical content.
It's unlikely to be wrong when there is actual content to
compare, and we already take care not to do inexact rename
detection when there is not enough content to produce good
results.
However, we always do exact rename detection, even when the
blob is tiny or empty. It's easy to get false positives with
an empty blob, simply because it is an obvious content to
use as a boilerplate (e.g., when telling git that an empty
directory is worth tracking via an empty .gitignore).
This patch lets callers specify whether or not they are
interested in using empty files as rename sources and
destinations. The default is "yes", keeping the original
behavior. It works by detecting the empty-blob sha1 for
rename sources and destinations.
One more flexible alternative would be to allow the caller
to specify a minimum size for a blob to be "interesting" for
rename detection. But that would catch small boilerplate
files, not large ones (e.g., if you had the GPL COPYING file
in many directories).
A better alternative would be to allow a "-rename"
gitattribute to allow boilerplate files to be marked as
such. I'll leave the complexity of that solution until such
time as somebody actually wants it. The complaints we've
seen so far revolve around empty files, so let's start with
the simple thing.

Pushing a non-fast-forward update to a remote repository will result in
an error, but the hint text doesn't provide the correct resolution in
every case. Give better resolution advice in three push scenarios:
1) If you push your current branch and it triggers a non-fast-forward
error, you should merge remote changes with 'git pull' before pushing
again.
2) If you push to a shared repository others push to, and your local
tracking branches are not kept up to date, the 'matching refs' default
will generate non-fast-forward errors on outdated branches. If this is
your workflow, the 'matching refs' default is not for you. Consider
setting the 'push.default' configuration variable to 'current' or
'upstream' to ensure only your current branch is pushed.
3) If you explicitly specify a ref that is not your current branch or
push matching branches with ':', you will generate a non-fast-forward
error if any pushed branch tip is out of date. You should checkout the
offending branch and merge remote changes before pushing again.
Teach transport.c to recognize these scenarios and configure push.c
to hint for them. If 'git push's default behavior changes or we
discover more scenarios, extension is easy. Standardize on the
advice API and add three new advice variables, 'pushNonFFCurrent',
'pushNonFFDefault', and 'pushNonFFMatching'. Setting any of these
to 'false' will disable their affiliated advice. Setting
'pushNonFastForward' to false will disable all three, thus preserving the
config option for users who already set it, but guaranteeing new
users won't disable push advice accidentally.

The following only concerns systems using X and the client-side font
rendering framework from freedesktop.org. Windows and Mac OS X are
not affected.
Starting with version 8.5, Tk uses freetype and fontconfig by default
to render fonts on platforms that support it. Gitk currently defaults
to the font Helvetica for the interface and Courier for diffs, and
both unfortunately look rather bad on screen in the default
configuration on many Linux distros with anti-aliasing and poor
hinting.
It is better to default to "sans" and "monospace", which are mapped by
fontconfig to some appropriate font of the sysadmin and user's
choosing (typically Bitstream Vera Sans and Mono). The result looks
more sensible and it makes gitk feel like a well-behaved software
citizen since its fonts match other native apps.
This patch does not change the appearance of gitk for users that have
already run it, since gitk uses the remembered UI and diff font names
from ~/.gitk.

The code to validate the history connectivity between old refs and new

inefficient and unnecessarily tried to re-validate integrity of individual
objects. This essentially reverts that performance regression.
* jc/maint-verify-objects-remove-pessimism:
fetch/receive: remove over-pessimistic connectivity check
Andrew Sayers noticed that the svn-fe | git fast-import pipeline
mishandles a subversion history that copies the root directory to a
sub-directory (e.g. doing `svn cp . trunk` to standardise your
layout). As David Barr explained, the bug arises when the following
command is sent to git fast-import:
'ls' SP ':1' SP LF
Instead of reading back what is at the root of r1, it unconditionally
reports the path as missing.
After sleeping on it, here are two patches for 'maint'. One plugs a
memory leak. The other ensures that trying to pass an empty path to
the 'ls' command results in an error message that can help the
frontend author instead of the silently broken conversion Andrew
found.
Then we can carefully add 'ls ""' support in 1.7.11.
* commit 'refs/pull-request-tags/jn/maint-fast-import-empty-ls':

contrib/diffall: eliminate duplicate while loops
contrib/diffall: eliminate use of tar
contrib/diffall: create tmp dirs without mktemp
contrib/diffall: comment actual reason for 'cdup'
Git 1.7.8 introduced an object and history re-validation step after
"fetch" or "push" causes new history to be added to a receiving
repository. This is to protect a malicious server or pushing client from
corrupting the repository by taking advantage of an existing corrupt
object that is unconnected to existing history.
But this check is way over-pessimistic. During "fetch" or "receive-pack"
(the server side of "push"), unpack-objects and index-pack already
validate individual objects that are received, and the only thing we would
want to catch are corrupted objects that already happen to exist in our
repository but are not referenced from our refs. Such objects must have
been written by an earlier run of our codepaths that write out loose
objects or packfiles, and they must have done the validation of individual
objects when they did so. The only thing left to worry about is the
connectivity integrity, which can be checked with "rev-list --objects",
which is much cheaper. We have been paying the 5x to 8x runtime overhead
the --verify-objects often adds for no real gain.
Revert check_everything_connected() not to use this over-pessimistic
check.
Credit goes to Nguyễn Thái Ngọc Duy, who originally identified the
performance regression and endured multiple rounds of reviews to fix it.

remove_dir_recursively() has a check to avoid removing the directory it

working tree of a nested git repository is in a subdirectory of a toplevel
project, however, this protection did not apply by mistake; we forgot to

codepath.
This requires us to also teach the higher level not to remove the

When a manual notes merge is committed or aborted, we need to remove the
temporary worktree at .git/NOTES_MERGE_WORKTREE. However, removing the
entire directory is not good if the user ran the 'git notes merge
--commit/--abort' from within that directory. On Windows, the directory
removal would simply fail, while on POSIX systems, users would suddenly
find themselves in an invalid current directory.
Therefore, instead of deleting the entire directory, we delete everything
_within_ the directory, and leave the (empty) directory in place.
This would cause a subsequent notes merge to abort, complaining about a
previous - unfinished - notes merge (due to the presence of
.git/NOTES_MERGE_WORKTREE), so we also need to adjust this check to only
trigger when .git/NOTES_MERGE_WORKTREE is non-empty.
Finally, adjust the t3310 manual notes merge testcases to correctly handle

notes_merge_commit() only needs to list all entries (non-recursively)
under a directory, which can be easily accomplished with
opendir/readdir and would be more lightweight than read_directory().
read_directory() is designed to list paths inside a working
directory. Using it outside of its scope may lead to undesired effects.
Apparently, one of the undesired effects of read_directory() is that it
doesn't deal with being given absolute paths. This creates problems for
notes_merge_commit() when git_path() returns an absolute path, which
happens when the current working directory is in a subdirectory of the

When using word diff, the code sets the word_regex from various
defaults if it was not set already. The problem is that it does this
on the original diff_options, which will also be used in subsequent
diffs.
This means that when the word_regex is not given on the command line,
only the first diff for which a setting for word_regex (either from
attributes or diff.wordRegex) ever takes effect. This value then
propagates to the rest of the diff runs and in particular prevents
further attribute lookups.
Fix the problem of changing diff state once and for all, by working
with a _copy_ of the diff_options.

When lying the author name via GIT_AUTHOR_NAME environment variable
to "git commit", the hooks run by the command saw it and could act
on the name that will be recorded in the final commit. When the user
uses the "--author" option from the command line, the command should
give the same information to the hook, and back when "git command"
was a scripted Porcelain, it did set the environment variable and
hooks can learn the author name from it.
However, when the command was reimplemented in C, the rewritten code
was not very faithful to the original, and hooks stopped getting the
authorship information given with "--author". Fix this by exporting

As the fast-import manual explains:
The value of <path> must be in canonical form. That is it must
not:
. contain an empty directory component (e.g. foo//bar is invalid),
. end with a directory separator (e.g. foo/ is invalid),
. start with a directory separator (e.g. /foo is invalid),
Unfortunately the "ls" command accepts these invalid syntaxes and
responds by declaring that the indicated path is missing. This is too
subtle and causes importers to silently misbehave; better to error out
so the operator knows what's happening.
The C, R, and M commands already error out for such paths.

This test asks for an impossible conversion to the system by
preparing an UTF-8 translation with characters that cannot be
expressed in ISO-8859-1, and then asking the message shown in
ISO-8859-1. Even though the behaviour against such a request is
undefined, it may be interesting to see what the system does, and
the purpose of this test is to see if there are platforms that
exhibit behaviour that we haven't seen.
The original recognized two known modes of behaviour:
- the key used to query the message catalog ("TEST: Old English
Runes"), saying "I cannot do that i18n".
- impossible characters replaced with ASCII "?", saying "I punt".
but they were treated totally differently. The test simply issued
an informational message "Your system punts on this one" for the
first error mode, while it diagnosed the latter as "Your system is
good; you pass!".
It turns out that Mac OS X exhibits a third mode of error behaviour,
to spew out the raw value stored in the message catalog. The test
diagnosed this behaviour as "broken", but it is merely trying to do
its best to respond to an impossible request by saying "I punt" in a
way that is slightly different from the second one.
Update the offending test to make it clear what is (and is not)
being tested, update the code structure so that newly discovered
error mode can easily be added to it later, and reword the message
that comes from a failing case to clarify that it is not the system
that is broken when it fails, but merely that the behaviour is not
something we have seen.

On a Solaris 10 system with Solaris make installed as '/usr/xpg4/bin/make',
GNU make installed as '/usr/local/bin/make', and with '/usr/local/bin'
appearing in $PATH *before* '/usr/xpg4/bin', I was seeing errors like this
upon invoking "make all":
Usage : make [ -f makefile ][ -K statefile ]...
make: Fatal error: Unknown option `-C'
This happenes because the Git's Makefile, when running on Solaris,
automatically "sanitizes" $PATH by prepending '/usr/xpg6/bin' and
'/usr/xpg4/bin' to it in order to avoid using non-POSIX /bin/sh from
being used. In the setup described above, however, this has an
unintended consequence of forcing the use of Solaris make in recursive
make invocations -- even if the $(MAKE) macro is being correctly used in
them!
When building without using the autoconf machinery, this can be solved
by overriding $(SANE_TOOL_PATH). Teach the autoconf machinery to also
allow users of ./configure to override it from the command line with a
new --with-sane-tool-path option.

Under Windows the "git rev-parse --git-dir" and "pwd" commands may return
either drive-letter-colon or POSIX style paths. This makes module_clone()
behave badly because it expects absolute paths to always start with a '/'.
Fix that by always converting the "c:/" notation into "/c/" when computing
the relative paths from gitdir to the submodule work tree and back.

In module_clone() the rel_gitdir variable was computed differently when
"git rev-parse --git-dir" returned a relative path than when it returned
an absolute path. This is not optimal, as different code paths are used
depending on the return value of that command.
Fix that by reusing the differing path components computed for setting the
core.worktree config setting, which leaves a single code path for setting
both instead of having three and makes the code much shorter.
This also fixes the bug that in the computation of how many directories
have to be traversed up to hit the root directory of the submodule the
name of the submodule was used where the path should have been used. This
lead to problems after renaming submodules into another directory level.
Even though the "(cd $somewhere && pwd)" approach breaks the flexibility
of symlinks, that is no issue here as we have to have one relative path
pointing from the work tree to the gitdir and another pointing back, which
will never work anyway when a symlink along one of those paths is changed
because the directory it points to was moved.
Also add a test moving a submodule into a deeper directory to catch any
future breakage here and to document what has to be done when a submodule
needs to be moved until git mv learns to do that. Simply moving it to the
new location doesn't work, as the core.worktree and possibly the gitfile
setting too will be wrong. So it has to be removed from filesystem and
index, then the new location has to be added into the index and the
.gitmodules file has to be updated. After that a git submodule update will
check out the submodule at the new location.

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. To make that work the git directory has
the core.worktree configuration set in its config file to point back to
the work tree.
That core.worktree is an absolute path set by the initial clone of the
submodule. A relative path is preferable here because it allows the
superproject to be moved around without invalidating that setting, so
compute and set that relative path after cloning or reactivating the
submodule.
This also fixes a bug when moving a submodule around inside the
superproject, as the current code forgot to update the setting to the new
submodule work tree location.

by accident and that moving a superproject won't break submodules.

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there. When the submodule git directory needs
to be cloned because it is not found in .git/modules/<name> the clone
command will write an absolute path into the gitfile. When no clone is
necessary the git directory will be reactivated by the git-submodule.sh
script by writing a relative path into the gitfile.
This is inconsistent, as the behavior depends on the submodule having been
cloned before into the .git/modules of the superproject. A relative path
is preferable here because it allows the superproject to be moved around
without invalidating the gitfile. We do that by always writing the
relative path into the gitfile, which overwrites the absolute path the
clone command may have written there.
This is only the first step to make superprojects movable again like they
were before the separate-git-dir approach was introduced. The second step
is to use a relative path in core.worktree too.
Enhance t7400 to ensure that future versions won't re-add absolute paths
by accident.
While at it also replace an if/else construct evaluating the presence

warning, therefore, we could replace the "git-compat-util.h" header
inclusion with "cache.h", since "cache.h" includes "git-compat-util.h"
in turn. Here, however, we choose to move the extern declaration for
'tolower_trans_tbl' into "git-compat-util.h", alongside the other
extern declaration from ctype.c for 'sane_ctype'.

The current wording of the http.proxy documentation suggests that
http_proxy is somehow equivalent to http.proxy. However, while
http.proxy (by the means of curl's CURLOPT_PROXY option) overrides the
proxy for both HTTP and HTTPS protocols, the http_proxy environment
variable is used only for HTTP. But since the docs mention only
http_proxy, a user might expect it to apply to all HTTP-like protocols.
Avoid any such misunderstanding by explicitly mentioning https_proxy and
all_proxy as well.
Also replace linkgit:curl[1] with a literal 'curl(1)', because the
former gets translated to a dead link in the HTML pages.

The construct 'while IFS== read' makes dash 0.5.6 execute
read without changing IFS, which results in test breakages
all over the place in t0300. Neither dash 0.5.5.1 and older
nor dash 0.5.7 and newer are affected: The problem was
introduded resp. fixed by the commits
55c46b7 ([BUILTIN] Honor tab as IFS whitespace when
splitting fields in readcmd, 2009-08-11)
1d806ac ([VAR] Do not poplocalvars prematurely on regular
utilities, 2010-05-27)
in http://git.kernel.org/?p=utils/dash/dash.git
Putting 'IFS==' before that line makes all versions of dash
work.
This looks like a dash bug, not a misinterpretation of the
standard. However, it's worth working around for two
reasons. One, this version of dash was released in Fedora
14-16, so the bug is found in the wild. And two, at least
one other shell, Solaris /bin/sh, choked on this by
persisting IFS after the read invocation. That is not a
shell we usually care about, and I think this use of IFS is
acceptable by POSIX (which allows other behavior near
"special builtins", but "read" is not one of those). But it
seems that this may be a subtle, not-well-tested case for
some shells. Given that the workaround is so simple, it's
worth just being defensive.

When the proxy server specified by the http.proxy configuration or the
http_proxy environment variable requires authentication, git failed to
connect to the proxy, because we did not configure the cURL handle with
CURLOPT_PROXYAUTH.
When a proxy is in use, and you tell git that the proxy requires
authentication by having username in the http.proxy configuration, an
extra request needs to be made to the proxy to find out what
authentication method it supports, as this patch uses CURLAUTH_ANY to let
the library pick the most secure method supported by the proxy server.
The extra round-trip adds extra latency, but relieves the user from the
burden to configure a specific authentication method. If it becomes
problem, a later patch could add a configuration option to specify what
method to use, but let's start simple for the time being.

The 'name' field passed to add_pending_object() is used to later
deduplicate in object_array_remove_duplicates().
git-bundle had a bug in this area since 18449ab (git-bundle: avoid
packing objects which are in the prerequisites, 2007-03-08): it passed
the name of each boundary object in a static buffer. In other words,
all that object_array_remove_duplicates() saw was the name of the
*last* added boundary object.
The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan
the log for boundary commits, 2012-02-22) made this slightly worse: we
now free the buffer at the end, so it is not even guaranteed that it
still points into addressable memory by the time object_array_remove_
duplicates looks at it. On the plus side however, it was now
detectable by valgrind.
The fix is easy: pass a copy of the string to add_pending_object.

The plumbing "diff" commands look at the working tree files without
refreshing the index themselves for performance reasons (the calling
script is expected to do that upfront just once, before calling one or
more of them). In the early days of git, they showed the "diff --git"
header before they actually ask the xdiff machinery to produce patches,
and ended up showing only these headers if the real contents are the same
and the difference they noticed was only because the stat info cached in
the index did not match that of the working tree. It was too late for the
implementation to take the header that it already emitted back.
But 3e97c7c (No diff -b/-w output for all-whitespace changes, 2009-11-19)
introduced necessary logic to keep the meta-information headers in a
strbuf and delay their output until the xdiff machinery noticed actual
changes. This was primarily in order to generate patches that ignore
whitespaces. When operating under "-w" mode, we wouldn't know if the
header is needed until we actually look at the resulting patch, so it was
a sensible thing to do, but we did not realize that the same reasoning
applies to stat-dirty paths.
Later, 296c6bb (diff: fix "git show -C -C" output when renaming a binary
file, 2010-05-26) generalized this machinery and added must_show_header
toggle. This is turned on when the header must be shown even when there
is no patch to be produced, e.g. only the mode was changed, or the path
was renamed, without changing the contents. However, when it did so, it
still kept the special case for the "-w" mode, which meant that the
plumbing would keep showing these phantom changes.
This corrects this historical inconsistency by allowing the plumbing to
omit paths that are only stat-dirty from its output in the same way as it
handles whitespace only changes under "-w" option.
The change in the behaviour can be seen in the updated test.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The plumbing that looks at the working tree, i.e. "diff-index" and
"diff-files", always emit the "diff --git a/path b/path" header lines
without anything else for paths that are only stat-dirty (i.e. different
only because the cached stat information in the index no longer matches
that of the working tree, but the real contents are the same), when
these commands are run with "-p" option to produce patches.
Illustrate this current behaviour. Also demonstrate that with the "-w"
option, we (correctly) hold off showing a "diff --git" header until actual
differences have been found. This also suppresses the header for merely
stat-dirty files, which is inconsistent.

The way that available columns are divided between the filename part
and the graph part is modified to use as many columns as necessary for
the filenames and the rest for the graph.
If there isn't enough columns to print both the filename and the
graph, at least 5/8 of available space is devoted to filenames. On a
standard 80 column terminal, or if not connected to a terminal and
using the default of 80 columns, this gives the same partition as
before.
The effect of this change is visible in the patch to the test vector
in t4052; with a small change with long filename, it stops truncating
the name part too short, and also allocates a bit more columns to the
graph for larger changes.

Default to the real terminal width for diff --stat output, instead
of the hard-coded 80 columns.
Some projects (especially in Java), have long filename paths, with
nested directories or long individual filenames. When files are
renamed, the filename part in stat output can be almost useless. If
the middle part between { and } is long (because the file was moved to
a completely different directory), then most of the path would be
truncated.
It makes sense to detect and use the full terminal width and display
full filenames if possible.
The are commands like diff, show, and log, which can adapt the output
to the terminal width. There are also commands like format-patch,
whose output should be independent of the terminal width. Since it is
safer to use the 80-column default, the real terminal width is only
used if requested by the calling code by setting diffopts.stat_width=-1.
Normally this value is 0, and can be set by the user only to a
non-negative value, so -1 is safe to use internally.
This patch only changes the diff builtin to use the full terminal width.

In preparation for updates to the "diff --stat" that updates the logic
to split the allotted columns into the name part and the graph part to
make the output more readable, add a handful of tests to document the
corner case behaviour in which long filenames and big changes are shown.
When a pathname is so long that it cannot fit on the column, the current
code truncates it to make sure that the graph part has enough room to show
a meaningful graph. If the actual change is small (e.g. only one line
changed), this results in the final output that is shorter than the width
we aim for.

"git log -S<string>" is a useful way to find the last commit in the
codebase that touched the <string>. As it was designed to be used by a
porcelain script to dig the history starting from a block of text that
appear in the starting commit, it never had to look for anything but an
exact match.
When used by an end user who wants to look for the last commit that
removed a string (e.g. name of a variable) that he vaguely remembers,
however, it is useful to support case insensitive match.
When given the "--regexp-ignore-case" (or "-i") option, which originally

Currently, with this commit, when searching projects there is always
shown full description of a project, and not a shortened one (like for
ordinary projects list view), even if the match is on project name and
not project description. Because we always show full description of a
project, and not possibly shortened name, there is no need for having
full description on mouseover via title attribute.
Showing full description when there is match on it is useful to avoid
situation where match is in shortened, invisible part. On the other
hand that makes project search different than projects list view; also
there can be problems with overly-long project descriptions.

Use esc_html_match_hl() introduced in previous commit to escape HTML
and mark match, using span element with 'match' class. Currently only
the 'path' part (i.e. the project name) is highlighted; match might be
on the project description. Highlighting match in description is left
for next commit.
The code makes use of the fact that defined $search_regexp means that
there was search going on.

The esc_html_match_hl() subroutine added in this commit will be used
to highlight *all* matches of given regexp, using 'match' class.
Ultimately it is to be used in all match highlighting, starting
with project search, which does not have it yet.
It uses the esc_html_hl_regions() subroutine, which is meant to
highlight in a given string a list of regions (given as a list of
[ beg, end ] pairs of positions in string), using HTML <span> element
with given class. It could probably be used in other places that
do highlighting of part of ready line, like highlighting of changes
in a diff (diff refinement highlighting).
Implementation and enhancement notes:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Currently esc_html_hl_regions() subroutine doesn't accept any
parameters, like esc_html() does. We might want for example to
pass nbsp=>1 to it.
It can easily be done with the following code:
my %opts = grep { ref($_) ne "ARRAY" } @sel;
@sel = grep { ref($_) eq "ARRAY" } @sel;
This allow adding parameters after or before regions, e.g.:
esc_html_hl_regions("foo bar", "mark", [ 0, 3 ], -nbsp => 1);
* esc_html_hl_regions() escapes like esc_html(); if we wanted to
highlight with esc_path(), we could pass subroutine reference
to now named esc_gen_hl_regions().
esc_html_hl_regions("foo bar", "mark", \&esc_path, [ 0, 3 ]);
Note that this way we can handle -nbsp=>1 case automatically,
e.g.
esc_html_hl_regions("foo bar", "mark",
sub { esc_html(@_, -nbsp=>1) },
[ 0, 3 ]);
* Alternate solution for highlighting region of a string would be to
use the idea that strings are to be HTML-escaped, and references to
scalars are HTML (like in the idea for generic committags).
This would require modifying gitweb code or esc_html to get list of
fragments, e.g.:
esc_html(\'<span class="mark">', 'foo', \'</span>', ' bar',
{ -nbsp => 1 });
or
esc_html([\'<span class="mark">', 'foo', \'</span>', ' bar'],
-nbsp=>1);
esc_html_match_hl() could be then simple wrapper around "match
formatter", e.g.
esc_html([ render_match_hl($str, $regexp) ], -nbsp=>1);

t/t9809-git-p4-client-view.sh
When "git grep" is run with -P/--perl-regexp, it doesn't match ^ and $ at
the beginning/end of the line. This is because PCRE normally matches ^
and $ at the beginning/end of the whole text, not for each line, and "git
grep" passes a large chunk of text (possibly containing many lines) to
pcre_exec() and then splits the text into lines.
This makes "git grep -P" behave differently from "git grep -E" and also
from "grep -P" and "pcregrep":
$ cat file
a
b
$ git grep --no-index -P '^ ' file
$ git grep --no-index -E '^ ' file
file: b
$ grep -c -P '^ ' file

$ pcregrep -c '^ ' file

Because git's object format requires us to specify the
number of bytes in the object in its header, we must know
the size before streaming a blob into the object database.
This is not a problem when adding a regular file, as we can
get the size from stat(). However, when filters are in use
(such as autocrlf, or the ident, filter, or eol
gitattributes), we have no idea what the ultimate size will
be.
The current code just punts on the whole issue and ignores
filter configuration entirely for files larger than
core.bigfilethreshold. This can generate confusing results
if you use filters for large binary files, as the filter
will suddenly stop working as the file goes over a certain
size. Rather than try to handle unknown input sizes with
streaming, this patch just turns off the streaming
optimization when filters are in use.
This has a slight performance regression in a very specific
case: if you have autocrlf on, but no gitattributes, a large
binary file will avoid the streaming code path because we
don't know beforehand whether it will need conversion or
not. But if you are handling large binary files, you should
be marking them as such via attributes (or at least not
using autocrlf, and instead marking your text files as
such). And the flip side is that if you have a large
_non_-binary file, there is a correctness improvement;
before we did not apply the conversion at all.
The first half of the new t1051 script covers these failures
on input. The second half tests the matching output code
paths. These already work correctly, and do not need any
adjustment.

When we call convert_to_git in dry-run mode, it may still
want to look at the source buffer, because some CRLF
conversion modes depend on analyzing the source to determine
whether it is in fact convertible CRLF text.
However, the main motivation for convert_to_git's dry-run
mode is that we would decide which method to use to acquire
the blob's data (streaming versus in-core). Requiring this
source analysis creates a chicken-and-egg problem. We are
better off simply guessing that anything we can't analyze
will end up needing conversion.
This patch lets a caller specify a NULL src buffer when
using dry-run mode (and only dry-run mode). A non-zero
return value goes from "we would convert" to "we might
convert"; a zero return value remains "we would definitely
not convert".

Some callers may want to know whether convert_to_git will
actually do anything before performing the conversion
itself (e.g., to decide whether to stream or handle blobs
in-core). This patch lets callers specify the dry run mode
by passing a NULL destination buffer. The return value,
instead of indicating whether conversion happened, will
indicate whether conversion would occur.
For readability, we also include a wrapper function which
makes it more obvious we are not actually performing the
conversion.

RCS keywords cause problems for git-p4 as perforce always
expands them (if +k is set) and so when applying the patch,
git reports that the files have been modified by both sides,
when in fact they haven't.
This change means that when git-p4 detects a problem applying
a patch, it will check to see if keyword expansion could be
the culprit. If it is, it strips the keywords in the p4
repository so that they match what git is expecting. It then
has another go at applying the patch.
This behaviour is enabled with a new git-p4 configuration
option and is off by default.

Before searching by some field the information we search for must be
filled in, but we do not have to fill other fields that are not
involved in the search.
To be able to request filling only specified fields,
fill_project_list_info() was enhanced in previous commit to take
additional parameters which specify part of projects info to fill.
This way we can limit doing expensive calculations (like running
git-for-each-ref to get 'age' / "Last changed" info) to doing those
only for projects which we will show as search results.
This commit actually uses this interface, changing gitweb code from
the following behavior
fill all project info on all projects
search projects
to behaving like this pseudocode
fill search fields on all projects
search projects
fill all project info on search results
With this commit the number of git commands used to generate search
results is 2*<matched projects> + 1, and depends on number of matched
projects rather than number of all projects (all repositories).
Note: this is 'git for-each-ref' to find last activity, and 'git config'
for each project, and 'git --version' once.
Example performance improvements, for search that selects 2
repositories out of 12 in total:
* Before (warm cache):
"This page took 0.867151 seconds and 27 git commands to generate."
* After (warm cache):
"This page took 0.673643 seconds and 5 git commands to generate."
Now imagine that they are 5 repositories out of 5000, and cold or

The heuristic used by "git merge" to decide if it automatically gives an
editor upon clean automerge is to see if the standard input and the
standard output is the same device and is a tty, we are in an interactive
session. "The same device" test was done by comparing fstat(2) result on
the two file descriptors (and they must match), and we asked isatty() only
for the standard input (we insist that they are the same device and there
is no point asking tty-ness of the standard output).
The stat(2) emulation in the Windows port however does not give a usable
value in the st_ino field, so even if the standard output is connected to
something different from the standard input, "The same device" test may
incorrectly return true. To accomodate it, add another isatty() check for
the standard output stream as well.

When git spawns a remote helper program (like git-remote-http),
the last thing we do before closing the pipe to the child
process is to send a blank line, telling the helper that we
are done issuing commands. However, the helper may already
have exited, in which case the parent git process will
receive SIGPIPE and die.
In particular, this can happen with the remote-curl helper
when it encounters errors during a push. The helper reports
individual errors for each ref back to git-push, and then
exits with a non-zero exit code. Depending on the exact
timing of the write, the parent process may or may not
receive SIGPIPE.
This causes intermittent test failure in t5541.8, and is a
side effect of 5238cbf (remote-curl: Fix push status report
when all branches fail). Before that commit, remote-curl
would not send the final blank line to indicate that the
list of status lines was complete; it would just exit,
closing the pipe. The parent git-push would notice the
closed pipe while reading the status report and exit
immediately itself, propagating the failing exit code. But
post-5238cbf, remote-curl completes the status list before
exiting, git-push actually runs to completion, and then it
tries to cleanly disconnect the helper, leading to the
SIGPIPE race above.
This patch drops all error-checking when sending the final
"we are about to hang up" blank line to helpers. There is
nothing useful for the parent process to do about errors at
that point anyway, and certainly failing to send our "we are
done with commands" line to a helper that has already exited
is not a problem.

The first part of the bundle header contains the boundary commits, and
could be approximated by
# v2 git bundle
$(git rev-list --pretty=oneline --boundary <ARGS> | grep ^-)
git-bundle actually spawns exactly this rev-list invocation, and does
the grepping internally.
There was a subtle bug in the latter step: it used fgets() with a
1024-byte buffer. If the user has sufficiently long subjects (e.g.,
by not adhering to the git oneline-subject convention in the first
place), the 'oneline' format can easily overflow the buffer. fgets()
then returns the rest of the line in the next call(s). If one of
these remaining parts started with '-', git-bundle would mistakenly
insert it into the bundle thinking it was a boundary commit.
Fix it by using strbuf_getwholeline() instead, which handles arbitrary
line lengths correctly.
Note that on the receiving side in parse_bundle_header() we were
already using strbuf_getwholeline_fd(), so that part is safe.

open_or_add_dir checks to see if the directory already exists or not.
If it already exists and is not a directory, then we fail. However,
open_or_add_dir did not previously account for the possibility that the
path did exist as a file, but is deleted in the current commit.
In order to prevent this legitimate case from failing, open_or_add_dir
needs to know what files are deleted in the current commit.
Unfortunately that information has to be plumbed through a couple of
layers.

If a filter is not defined or if it fails, git should behave as if the
filter is a no-op passthru.
However, if the filter exits before reading all the content, depending on
the timing, git could be killed with SIGPIPE when it tries to write to the
pipe connected to the filter.
Ignore SIGPIPE while processing the filter to give us a chance to check
the return value from a failed write, in order to detect and act on this

In a repository whose HEAD points to an unborn branch with no commits,
"heads" view and "summary" view (which shows what is shown in "heads"
view) compared the object names of commits at the tip of branches with the
output from "git rev-parse HEAD", which caused comparison of a string with
undef and resulted in a warning in the server log.
This can happen if non-bare repository (with default 'master' branch)
is updated not via committing but by other means like push to it, or
Gerrit. It can happen also just after running "git checkout --orphan
<new branch>" but before creating any new commit on this branch.
Rewrite the comparison so that it also works when $head points at nothing;
in such a case, no branch can be "the current branch", add a test for it.
While at it, rename local variable $head to $head_at, as it points to
current commit rather than current branch name (HEAD contents).
The code still incorrectly shows all branches that point at the same
commit as what HEAD points as "the current branch", even when HEAD is
detached. Fixing this bug is outside the scope of this patch.

This introduces a performance testing framework under t/perf/. It
tries to be as close to the test-lib.sh infrastructure as possible,
and thus should be easy to get used to for git developers.
The following points were considered for the implementation:
1. You usually want to compare arbitrary revisions/build trees against
each other. They may not have the performance test under
consideration, or even the perf-lib.sh infrastructure.
To cope with this, the 'run' script lets you specify arbitrary
build dirs and revisions. It even automatically builds the revisions
if it doesn't have them at hand yet.
2. Usually you would not want to run all tests. It would take too
long anyway. The 'run' script lets you specify which tests to run;
or you can also do it manually. There is a Makefile for
discoverability and 'make clean', but it is not meant for
real-world use.
3. Creating test repos from scratch in every test is extremely
time-consuming, and shipping or downloading such large/weird repos
is out of the question.
We leave this decision to the user. Two different sizes of test
repos can be configured, and the scripts just copy one or more of
those (using hardlinks for the object store). By default it tries
to use the build tree's git.git repository.
This is fairly fast and versatile. Using a copy instead of a clone
preserves many properties that the user may want to test for, such
as lots of loose objects, unpacked refs, etc.

It can be useful to split your ~/.gitconfig across multiple
files. For example, you might have a "main" file which is
used on many machines, but a small set of per-machine
tweaks. Or you may want to make some of your config public
(e.g., clever aliases) while keeping other data back (e.g.,
your name or other identifying information). Or you may want
to include a number of config options in some subset of your
repos without copying and pasting (e.g., you want to
reference them from the .git/config of participating repos).
This patch introduces an include directive for config files.
It looks like:
[include]
path = /path/to/file
This is syntactically backwards-compatible with existing git
config parsers (i.e., they will see it as another config
entry and ignore it unless you are looking up include.path).
The implementation provides a "git_config_include" callback
which wraps regular config callbacks. Callers can pass it to
git_config_from_file, and it will transparently follow any
include directives, passing all of the discovered options to
the real callback.
Include directives are turned on automatically for "regular"
git config parsing. This includes calls to git_config, as
well as calls to the "git config" program that do not
specify a single file (e.g., using "-f", "--global", etc).
They are not turned on in other cases, including:
1. Parsing of other config-like files, like .gitmodules.
There isn't a real need, and I'd rather be conservative
and avoid unnecessary incompatibility or confusion.
2. Reading single files via "git config". This is for two
reasons:
a. backwards compatibility with scripts looking at
config-like files.
b. inspection of a specific file probably means you
care about just what's in that file, not a general
lookup for "do we have this value anywhere at
all". If that is not the case, the caller can
always specify "--includes".
3. Writing files via "git config"; we want to treat
include.* variables as literal items to be copied (or
modified), and not expand them. So "git config
--unset-all foo.bar" would operate _only_ on
.git/config, not any of its included files (just as it
also does not operate on ~/.gitconfig).

This is a magic global variable that was intended as an
override to the usual git-config lookup process. Once upon a
time, you could specify GIT_CONFIG to any git program, and
it would look only at that file. This turned out to be
confusing and cause a lot of bugs for little gain. As a
result, dc87183 (Only use GIT_CONFIG in "git config", not
other programs, 2008-06-30) took this away for all callers
except git-config.
Since git-config no longer uses it either, the variable can
just go away. As the diff shows, nobody was setting to
anything except NULL, so we can just replace any sites where
it was read with NULL.

The git-config command sometimes operates on the default set
of config files (either reading from all, or writing to repo
config), and sometimes operates on a specific file. In the
latter case, we set the magic global config_exclusive_filename,
and the code in config.c does the right thing.
Instead, let's have git-config use the "advanced" variants
of config.c's functions which let it specify an individual
filename (or NULL for the default). This makes the code a
lot more obvious, and fixes two small bugs:
1. A relative path specified by GIT_CONFIG=foo will look
in the wrong directory if we have to chdir as part of
repository setup. We already handle this properly for
"git config -f foo", but the GIT_CONFIG lookup used
config_exclusive_filename directly. By dropping to a
single magic variable, the GIT_CONFIG case now just
works.
2. Calling "git config -f foo --edit" would not respect
core.editor. This is because just before editing, we
called git_config, which would respect the
config_exclusive_filename setting, even though this
particular git_config call was not about looking in the
user's specified file, but rather about loading actual
git config, just as any other git program would.

Callers may want to provide a specific version of a file in which to look
for config. Right now this can be done by setting the magic global
config_exclusive_filename variable. By providing a version of git_config
that takes a filename, we can take a step towards making this magic global
go away.
Furthermore, by providing a more "advanced" interface, we now have a a
natural place to add new options for callers like git-config, which care
about tweaking the specifics of config lookup, without disturbing the
large number of "simple" users (i.e., every other part of git).
The astute reader of this patch may notice that the logic for handling
config_exclusive_filename was taken out of git_config_early, but added
into git_config. This means that git_config_early will no longer respect
config_exclusive_filename. That's OK, because the only other caller of
git_config_early is check_repository_format_gently, but the only function
which sets config_exclusive_filename is cmd_config, which does not call
check_repository_format_gently (and if it did, it would have been a bug,
anyway, as we would be checking the repository format in the wrong file).

Callers which want to write to the default location must use
the regular, non-"in_file" version, which will either write
to config_exclusive_filename, or to the repo config if the
exclusive filename is NULL.
Let's migrate the "default to using repo config" logic into
the "in_file" form. That will let callers get the same
default-if-NULL behavior as one gets with

By default, a missing filter driver or a failure from the filter driver is
not an error, but merely makes the filter operation a no-op pass through.
This is useful to massage the content into a shape that is more convenient
for the platform, filesystem, and the user to use, and the content filter
mechanism is not used to turn something unusable into usable.
However, we could also use of the content filtering mechanism and store
the content that cannot be directly used in the repository (e.g. a UUID
that refers to the true content stored outside git, or an encrypted
content) and turn it into a usable form upon checkout (e.g. download the
external content, or decrypt the encrypted content). For such a use case,
the content cannot be used when filter driver fails, and we need a way to
tell Git to abort the whole operation for such a failing or missing filter
driver.
Add a new "filter.<driver>.required" configuration variable to mark the
second use case. When it is set, git will abort the operation when the
filter driver does not exist or exits with a non-zero status code.

When commit 3ed74e6 (diff --stat: ensure at least one '-' for deletions,
and one '+' for additions, 2006-09-28) improved the output for files with
tiny modifications, we accidentally broke the logic to ensure that two
equal sized changes are shown with the bars of the same length, even when
rounding errors exist.
Compute the length of the graph bars, using the same "non-zero changes is
shown with at least one column" scaling logic, but by scaling the sum of
additions and deletions to come up with the total length of the bar (this
ensures that two equal sized changes result in bars of the same length),
and then scaling the smaller of the additions or deletions. The other side
is computed as the difference between the two.
This makes the apportioning between additions and deletions less accurate
due to rounding errors, but it is much less noticeable than two files with
the same amount of change showing bars of different length.

Currently we only bother highlighting single-line hunks. The
rationale was that the purpose of highlighting is to point
out small changes between two similar lines that are
otherwise hard to see. However, that meant we missed similar
cases where two lines were changed together, like:
-foo(buf);
-bar(buf);
+foo(obj->buf);
+bar(obj->buf);
Each of those changes is simple, and would benefit from
highlighting (the "obj->" parts in this case).
This patch considers whole hunks at a time. For now, we
consider only the case where the hunk has the same number of
removed and added lines, and assume that the lines from each
segment correspond one-to-one. While this is just a
heuristic, in practice it seems to generate sensible
results (especially because we now omit highlighting on
completely-changed lines, so when our heuristic is wrong, we
tend to avoid highlighting at all).

If you have a change like:
-foo
+bar
we end up highlighting the entirety of both lines (since the
whole thing is changed). But the point of diff highlighting
is to pinpoint the specific change in a pair of lines that
are mostly identical. In this case, the highlighting is just
noise, since there is nothing to pinpoint, and we are better
off doing nothing.
The implementation looks for "interesting" pairs by checking
to see whether they actually have a matching prefix or
suffix that does not simply consist of colorization and
whitespace. However, the implementation makes it easy to
plug in other heuristics, too, like:
1. Depending on the source material, the set of "boring"
characters could be tweaked to include language-specific
stuff (like braces or semicolons for C).
2. Instead of saying "an interesting line has at least one
character of prefix or suffix", we could require that
less than N percent of the line be highlighted.
The simple "ignore whitespace, and highlight if there are
any matched characters" implemented by this patch seems to
give good results on git.git. I'll leave experimentation
with other heuristics to somebody who has a dataset that
does not look good with the current code.

"cc" is a symlink to clang, and on a Solaris box I have access to "cc"
is Sun Studio's CC.
Both of these are perfectly capable of compiling Git, and it's
annoying to have to specify CC=cc on the command-line when compiling
Git when that's the default behavior of most other portable programs.
So change the default to "cc". Users who want to compile with GCC can
still add "CC=gcc" to the make(1) command-line, but those users who
don't have GCC as their "cc" will see expected behavior, and as a
bonus we'll be more likely to smoke out new compilation warnings from
our distributors since they'll me using a more varied set of compilers
by default.

Ok, so now "git merge" defaults to editing when interactive - lovely. But
when testing that, I noticed that while you can say
git merge --[no-]edit ..branch..
that does not work with "git pull". You get a message like
error: unknown option `no-edit'
usage: git fetch [<options>] [<repository> [<refspec>...]]

or: git fetch --multiple [<options>] [(<repository> | <group>)...]
or: git fetch --all [<options>]
-v, --verbose be more verbose
-q, --quiet be more quiet
--all fetch from all remotes

which is because that stupid shell script doesn't know about the new
flags, and just passes it to "git fetch" instead.
Now, I really wanted to just make "git pull" a built-in instead of that
nasty shell script, but I'm lazy. So here's the trivial updates to

In v1.7.7-rc0~3^2 (2011-08-19), git mergetool's "meld" support learned
to use the --output option when calling versions of meld that are
detected to support it (1.5.0 and newer, hopefully).
Alas, it misdetects old versions (before 1.1.5, 2006-06-11) of meld as
supporting the option, so on systems with such meld, instead of
getting a nice merge helper, the operator gets a dialog box with the
text "Wrong number of arguments (Got 5)". (Version 1.1.5 is when meld
switched to using optparse. One consequence of that change was that
errors in usage are detected and signalled through the exit status
even when --help was passed.)
Luckily there is a simpler check that is more reliable: the usage
string printed by "meld --help" reliably reflects whether --output is
supported in a given version. Use it.

"git tag -n" did not check the type of the object it is reading the top n

As the payload of a tag and a commit look similar in that they both start
with a header block, which is skipped for the purpose of "-n" output,
followed by human readable text, allow the message of commit objects to be

Originally, "git add -N" was introduced to help users from forgetting to
add new files to the index before they ran "git commit -a". As an attempt
to help them further so that they do not forget to say "-a", "git commit"
to commit the index as-is was taught to error out, reminding the user that
they may have forgotten to add the final contents of the paths before
running the command.
This turned out to be a false "safety" that is useless. If the user made
changes to already tracked paths and paths added with "git add -N", and
then ran "git add" to register the final contents of the paths added with
"git add -N", "git commit" will happily create a commit out of the index,
without including the local changes made to the already tracked paths. It
was not a useful "safety" measure to prevent "forgetful" mistakes from
happening.
It turns out that this behaviour is not just a useless false "safety", but
actively hurts use cases of "git add -N" that were discovered later and
have become popular, namely, to tell Git to be aware of these paths added
by "git add -N", so that commands like "git status" and "git diff" would
include them in their output, even though the user is not interested in
including them in the next commit they are going to make.
Fix this ancient UI mistake, and instead make a commit from the index
ignoring the paths added by "git add -N" without adding real contents.

sanity from Jonathan Nieder and others on the Git mailing list.

When the userdiff_config function was introduced in be58e70
(diff: unify external diff and funcname parsing code,
2008-10-05), it used a return value convention unlike any
other config callback. Like other callbacks, it used "-1" to
signal error. But it returned "1" to indicate that it found
something, and "0" otherwise; other callbacks simply
returned "0" to indicate that no error occurred.
This distinction was necessary at the time, because the
userdiff namespace overlapped slightly with the color
configuration namespace. So "diff.color.foo" could mean "the
'foo' slot of diff coloring" or "the 'foo' component of the
"color" userdiff driver". Because the color-parsing code
would die on an unknown color slot, we needed the userdiff
code to indicate that it had matched the variable, letting
us bypass the color-parsing code entirely.
Later, in 8b8e862 (ignore unknown color configuration,
2009-12-12), the color-parsing code learned to silently
ignore unknown slots. This means we no longer need to
protect userdiff-matched variables from reaching the
color-parsing code.
We can therefore change the userdiff_config calling
convention to a more normal one. This drops some code from
each caller, which is nice. But more importantly, it reduces
the cognitive load for readers who may wonder why
userdiff_config is unlike every other config callback.
There's no need to add a new test confirming that this
works; t4020 already contains a test that sets
diff.color.external.

Because applying such a patch has no effect to the index, this is a

This patch also loses the "-dirty" suffix from the output when the HEAD of

As such dirtiness expressed by the suffix does not affect the result of

When listing commands in zsh (git <TAB><TAB>), all of them will show up,

The root cause of this is because zsh versions from 4.3.0 to present
(4.3.15) do not correctly propagate the SH_WORD_SPLIT option into the
subshell in ${foo:=$(bar)} expressions. Because of this bug, the list of
all commands was treated as a single word in __git_list_porcelain_commands
and did not match any of the patterns that would usually cause plumbing to
be excluded.
With problematic versions of zsh, after running
emulate sh
fn () {
var='one two'
for v in $var; do echo $v; done
}
x=$(fn)
: ${y=$(fn)}
printing "$x" results in two lines as expected, but printing "$y" results
in a single line because $var is expanded as a single word when evaluating
fn to compute y.

instead.

The callers of map_user() give email and name to it, and expect to get the
up-to-date email and/or name to be used in their output. The function
rewrites the given buffers in place. To optimize the majority of cases,
the function returns 0 when it did not do anything, and it returns 1 when
the caller should use the updated contents.
The 'email' input to the function is terminated by '>' or a NUL (whichever
comes first) for historical reasons, but when a rewrite happens, the value
is replaced with the mailbox inside the <> pair. However, it failed to
meet this expectation when it only rewrote the name part without rewriting
the email part, and the email in the input was terminated by '>'.
This causes an extra '>' to appear in the output of "blame -e", because the
caller does send in '>'-terminated email, and when the function returned 1
to tell it that rewriting happened, it appends '>' that is necessary when
the email part was rewritten.
The patch looks bigger than it actually is, because this change makes a
variable that points at the end of the email part in the input 'p' live
much longer than it used to, deserving a more descriptive name.

There was a number of problems I ran into when trying the
profile-directed optimizations added by Andi Kleen in git commit
7ddc2710b9. (This was using gcc 4.4 found on many enterprise
distros.)
1) The -fprofile-generate and -fprofile-use commands are incompatible
with ccache; the code ends up looking in the wrong place for the gcda
files based on the ccache object names.
2) If the makefile notices that CFLAGS are different, it will rebuild
all of the binaries. Hence the recipe originally specified by the
INSTALL file ("make profile-all" followed by "make install") doesn't
work. It will appear to work, but the binaries will end up getting
built with no optimization.
This patch fixes this by using an explicit set of options passed via
the PROFILE variable then using this to directly manipulate CFLAGS and
EXTLIBS.
The developer can run "make PROFILE=BUILD all ; sudo make
PROFILE=BUILD install" automatically run a two-pass build with the
test suite run in between as the sample workload for the purpose of
recording profiling information to do the profile-directed
optimization.
Alternatively, the profiling version of binaries can be built using:
make PROFILE=GEN PROFILE_DIR=/var/cache/profile all
make PROFILE=GEN install
and then after git has been used for a while, the optimized version of
the binary can be built as follows:
make PROFILE=USE PROFILE_DIR=/var/cache/profile all
make PROFILE=USE install

$ git checkout master
: ah, let's write it down before we forget what we were doing
$ git branch --edit-description my-tpoic
The command does not notice that branch 'my-tpoic' does not exist. It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful. So detect such a case and error out to reduce the grief
factor from this common mistake.
This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.

Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.
Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:
$ git checkout -b frotz v1.7.9~30
$ git merge --ff-only v1.7.9
and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:
fatal: Not possible to fast-forward, aborting.
because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.
We could teach users that now they have to do
$ git merge --ff-only v1.7.9^0
but it is far more pleasant for users if we DWIMmed this ourselves.
When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,
this change should not regress the support for the use case v1.7.9 wanted
to add.

The only place that the issue this series addresses was observed
where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE
in order to replay a commit with an ancient timestamp.
With the previous patch alone, "git commit --date='20100917 +0900'"
can be misinterpreted to mean an ancient timestamp, not September in
year 2010. Guard this codepath by requring an extra '@' in front of
the raw git timestamp on the parsing side. This of course needs to
be compensated by updating get_author_ident_from_commit and the code
for "git commit --amend" to prepend '@' to the string read from the

The date-time parser parses out a human-readble datestring piece by
piece, so that it could even parse a string in a rather strange
notation like 'noon november 11, 2005', but restricts itself from
parsing strings in "<seconds since epoch> <timezone>" format only
for reasonably new timestamps (like 1974 or newer) with 10 or more
digits. This is to prevent a string like "20100917" from getting
interpreted as seconds since epoch (we want to treat it as September
17, 2010 instead) while doing so.
The same codepath is used to read back the timestamp that we have
already recorded in the headers of commit and tag objects; because
of this, such a commit with timestamp "0 +0000" cannot be rebased or
amended very easily.
Teach parse_date() codepath to special case a string of the form
"<digits> +<4-digits>" to work this issue around, but require that
there is no other cruft around the string when parsing a timestamp
of this format for safety.
Note that this has a slight backward incompatibility implications.

t0300 creates some helper shell scripts, and marks them with
"!/bin/sh". Even though the scripts are fairly simple, they
can fail on broken shells (specifically, Solaris /bin/sh
will persist a temporary assignment to IFS in a "read"

Rather than work around the problem for Solaris /bin/sh,

Many of the scripts in the test suite write small helper
shell scripts to disk. It's best if these shell scripts
start with "#!$SHELL_PATH" rather than "#!/bin/sh", because
/bin/sh on some platforms is too buggy to be used.
However, it can be cumbersome to expand $SHELL_PATH, because
the usual recipe for writing a script is:
cat >foo.sh <<-\EOF
#!/bin/sh
echo my arguments are "$@"
EOF
To expand $SHELL_PATH, you have to either interpolate the
here-doc (which would require quoting "\$@"), or split the
creation into two commands (interpolating the $SHELL_PATH
line, but not the rest of the script). Let's provide a
helper function that makes that less syntactically painful.
While we're at it, this helper can also take care of the
"chmod +x" that typically comes after the creation of such a
script, saving the caller a line.

The current askpass code simply dies if calling an askpass
helper fails. Worse, in some failure modes it doesn't even
print an error (if start_command fails, then it prints its
own error; if reading fails, we print an error; but if the
command exits non-zero, finish_command fails and we print
nothing!).
Let's be more kind to the user by printing an error message
when askpass doesn't work out, and then falling back to the
terminal (which also may fail, of course, but we die already
there with a nice message).
While we're at it, let's clean up the existing error
messages a bit. Now that our prompts are very long and
contain quotes and colons themselves, our error messages are
hard to read.

$ echo $?
128
[before, with no terminal, and we must give up]
$ setsid git push
fatal: could not read 'Password for 'https://peff@github.com': ': No such device or address

Gitweb forgot to turn query parameters into UTF-8. This results in a bug
that one cannot search for a string with characters outside US-ASCII. For
example searching for "Michał Kiedrowicz" (containing letter 'ł' - LATIN
SMALL LETTER L WITH STROKE, with Unicode codepoint U+0142, represented
with 0xc5 0x82 bytes in UTF-8 and percent-encoded as %C5%82) result in the
following incorrect data in search field
MichaÅ\202 Kiedrowicz
This is caused by CGI by default treating '0xc5 0x82' bytes as two
characters in Perl legacy encoding latin-1 (iso-8859-1), because 's'
query parameter is not processed explicitly as UTF-8 encoded string.
The solution used here follows "Using Unicode in a Perl CGI script"
article on http://www.lemoda.net/cgi/perl-unicode/index.html:
use CGI;
use Encode 'decode_utf8;
my $value = params('input');
$value = decode_utf8($value);
Decoding UTF-8 is done when filling %input_params hash and $path_info
variable; the former requires to move from explicit $cgi->param(<label>)
to $input_params{<name>} in a few places, which is a good idea anyway.
Also add -override=>1 parameter to $cgi->textfield() invocation in search
form. Otherwise CGI would use values from query string if it is present,
filling value from $cgi->param... without decode_utf8(). As we are using
value of appropriate parameter anyway, -override=>1 doesn't change the
situation but makes gitweb fill search field correctly.
We could simply use the '-utf8' pragma (via "use CGI '-utf8';") to solve
this, but according to CGI.pm documentation, it may cause problems with
POST requests containing binary files, and it requires CGI 3.31 (I think),
released with perl v5.8.9.

When you specify a local repository on the command line of
clone, ls-remote, upload-pack, receive-pack, or upload-archive,
or in a request to git-daemon, we perform a little bit of
lookup magic, doing things like looking in working trees for
.git directories and appending ".git" for bare repos.
For clone, this magic happens in get_repo_path. For
everything else, it happens in enter_repo. In both cases,
there are some ambiguous or confusing cases that aren't
handled well, and there is one case that is not handled the
same by both methods.
This patch tries to provide (and test!) standard, sensible
lookup rules for both code paths. The intended changes are:
1. When looking up "foo", we have always preferred
a working tree "foo" (containing "foo/.git" over the
bare "foo.git". But we did not prefer a bare "foo" over
"foo.git". With this patch, we do so.
2. We would select directories that existed but didn't
actually look like git repositories. With this patch,
we make sure a selected directory looks like a git
repo. Not only is this more sensible in general, but it
will help anybody who is negatively affected by change
(1) negatively (e.g., if they had "foo.git" next to its
separate work tree "foo", and expect to keep finding
"foo.git" when they reference "foo").
3. The enter_repo code path would, given "foo", look for
"foo.git/.git" (i.e., do the ".git" append magic even
for a repo with working tree). The clone code path did
not; with this patch, they now behave the same.
In the unlikely case of a working tree overlaying a bare
repo (i.e., a ".git" directory _inside_ a bare repo), we
continue to treat it as a working tree (prefering the
"inner" .git over the bare repo). This is mainly because the
combination seems nonsensical, and I'd rather stick with
existing behavior on the off chance that somebody is relying
on it.

On 32-bit architectures with 64-bit file offsets, gcc 4.3 and earlier

The warning appears even when gcc is run without any warning flags
(this is gcc bug 12963). In later versions the same warning can be
reproduced with -Wtype-limits, which is implied by -Wextra.
On 64-bit architectures it really is possible for a size_t not to be
representable as an off_t so the check this is warning about is not
actually redundant. But even false positives are distracting. Avoid
the warning by making the "len" argument to check_overflow a
uintmax_t; no functional change intended.

There is no reason in principle that an svn-format dump would not be
able to represent a file whose length does not fit in a 32-bit
integer. Use off_t consistently to represent file lengths (in place
of using uint32_t in some contexts) so we can handle that.
Most svn-fe code is already ready to do that without this patch and
passes values of type off_t around. The type mismatch from stragglers
was noticed with gcc -Wtype-limits.
While at it, tighten the parsing of the Text-content-length field to
make sure it is a number and does not overflow, and tighten other
overflow checks as that value is passed around and manipulated.

The low-level grep_source code will automatically load the
userdiff driver to see whether a file is binary. However,
when we are threaded, it will load the drivers in a
non-deterministic order, handling each one as its assigned
thread happens to be scheduled.
Meanwhile, the attribute lookup code (which underlies the
userdiff driver lookup) is optimized to handle paths in
sequential order (because they tend to share the same
gitattributes files). Multi-threading the lookups destroys
the locality and makes this optimization less effective.
We can fix this by pre-loading the userdiff driver in the
main thread, before we hand off the file to a worker thread.
My best-of-five for "git grep foo" on the linux-2.6
repository went from:
real 0m0.391s
user 0m1.708s
sys 0m0.584s
to:
real 0m0.360s
user 0m1.576s
sys 0m0.572s
Not a huge speedup, but it's quite easy to do. The only
trick is that we shouldn't perform this optimization if "-a"
was used, in which case we won't bother checking whether
the files are binary at all.

Usually we load each file to grep into memory, check whether
it's binary, and then either grep it (the default) or not
(if "-I" was given).
In the "-I" case, we can skip loading the file entirely if
it is marked as binary via gitattributes. On my giant
3-gigabyte media repository, doing "git grep -I foo" went
from:
real 0m0.712s
user 0m0.044s
sys 0m4.780s
to:
real 0m0.026s
user 0m0.016s
sys 0m0.020s
Obviously this is an extreme example. The repo is almost
entirely binary files, and you can see that we spent all of
our time asking the kernel to read() the data. However, with
a cold disk cache, even avoiding a few binary files can have
an impact.

There is currently no way for users to tell git-grep that a
particular path is or is not a binary file; instead, grep
always relies on its auto-detection (or the user specifying
"-a" to treat all binary-looking files like text).
This patch teaches git-grep to use the same attribute lookup
that is used by git-diff. We could add a new "grep" flag,
but that is unnecessarily complex and unlikely to be useful.
Despite the name, the "-diff" attribute (or "diff=foo" and
the associated diff.foo.binary config option) are really
about describing the contents of the path. It's simply
historical that diff was the only thing that cared about
these attributes in the past.
And if this simple approach turns out to be insufficient, we
still have a backwards-compatible path forward: we can add a
separate "grep" attribute, and fall back to respecting
"diff" if it is unset.

Right now, grep only uses the userdiff_driver for one thing:
looking up funcname patterns for "-p" and "-W". As new uses
for userdiff drivers are added to the grep code, we want to
minimize attribute lookups, which can be expensive.
It might seem at first that this would also optimize multiple
lookups when the funcname pattern for a file is needed
multiple times. However, the compiled funcname pattern is
already cached in struct grep_opt's "priv" member, so
multiple lookups are already suppressed.

Before the grep_source interface existed, grep_buffer was
used by two types of callers:
1. Ones which pulled a file into a buffer, and then wanted
to supply the file's name for the output (i.e.,
git grep).
2. Ones which really just wanted to grep a buffer (i.e.,
git log --grep).
Callers in set (1) should now be using grep_source. Callers
in set (2) always pass NULL for the "name" parameter of
grep_buffer. We can therefore get rid of this now-useless
parameter.

The grep_source interface (as opposed to grep_buffer) will
eventually gives us a richer interface for telling the
low-level grep code about our buffers. Eventually this will
lead to things like better binary-file handling. For now, it
lets us drop a lot of now-redundant code.
The conversion is mostly straight-forward. One thing to note
is that the memory ownership rules for "struct grep_source"
are different than the "struct work_item" found here (the
former will copy things like the filename, rather than
taking ownership). Therefore you will also see some slight
tweaking of when filename buffers are released.

The main interface to the low-level grep code is
grep_buffer, which takes a pointer to a buffer and a size.
This is convenient and flexible (we use it to grep commit
bodies, files on disk, and blobs by sha1), but it makes it
hard to pass extra information about what we are grepping
(either for correctness, like overriding binary
auto-detection, or for optimizations, like lazily loading
blob contents).
Instead, let's encapsulate the idea of a "grep source",
including the buffer, its size, and where the data is coming
from. This is similar to the diff_filespec structure used by
the diff code (unsurprising, since future patches will
implement some of the same optimizations found there).
The diffstat is slightly scarier than the actual patch
content. Most of the modified lines are simply replacing
access to raw variables with their counterparts that are now
in a "struct grep_source". Most of the added lines were
taken from builtin/grep.c, which partially abstracted the
idea of grep sources (for file vs sha1 sources).
Instead of dropping the now-redundant code, this patch
leaves builtin/grep.c using the traditional grep_buffer
interface (which now wraps the grep_source interface). That
makes it easy to test that there is no change of behavior
(yet).

The low-level grep code traditionally didn't care about
threading, as it doesn't do any threading itself and didn't
call out to other non-thread-safe code. That changed with
0579f91 (grep: enable threading with -p and -W using lazy
attribute lookup, 2011-12-12), which pushed the lookup of
funcname attributes (which is not thread-safe) into the
low-level grep code.
As a result, the low-level code learned about a new global
"grep_attr_mutex" to serialize access to the attribute code.
A multi-threaded caller (e.g., builtin/grep.c) is expected
to initialize the mutex and set "use_threads" in the
grep_opt structure. The low-level code only uses the lock if
use_threads is set.
However, putting the use_threads flag into the grep_opt
struct is not the most logical place. Whether threading is
in use is not something that matters for each call to
grep_buffer, but is instead global to the whole program
(i.e., if any thread is doing multi-threaded grep, every
other thread, even if it thinks it is doing its own
single-threaded grep, would need to use the locking). In
practice, this distinction isn't a problem for us, because
the only user of multi-threaded grep is "git-grep", which
does nothing except call grep.
This patch turns the opt->use_threads flag into a global
flag. More important than the nit-picking semantic argument
above is that this means that the locking functions don't
need to actually have access to a grep_opt to know whether
to lock. Which in turn can make adding new locks simpler, as
we don't need to pass around a grep_opt.

list file).
Reusing $project instead of adding a new parameter would have been

Use of the filter option of git_get_projects_list is currently limited
to forks. It currently assumes the project belonging to the filter
directory was already validated to be visible in the project list.
To make it more generic add an optional argument to denote visibility
verification is still needed.
If there is a projects list file (GITWEB_LIST) only projects from
this list are returned anyway, so no more checks needed.
If there is no projects list file and the caller requests strict
checking (GITWEB_STRICT_EXPORT), do not jump directly to the
given directory but instead do a normal search and filter the
results instead.
The only effect of GITWEB_STRICT_EXPORT without GITWEB_LIST is to make
sure no project can be viewed without also be found starting from
project root. git_get_projects_list without this patch does not enforce
this but all callers only call it with a filter already checked this
way. With this parameter a caller can request this check if the filter
cannot be checked this way.

Curiously, pre_len given to read_length() does not trigger the same warning

read_offset() is used only once and inlining it will make gcc realize that

it does not help X-<.

This simplifies svn-fe a great deal and fulfills a longstanding wish:
support for dumps with deltas in them, and incremental imports.
The cost is that commandline usage of the svn-fe tool becomes a little
more complicated since it no longer keeps state itself but instead reads
blobs back from fast-import in order to copy them between revisions and
apply deltas to them.
Also removes a couple of custom data structures and replaces them with
strbufs like other parts of Git.

zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS
doesn't contain spaces. This issue has been reported[1], but there is no
solution yet.
This wasn't a problem due to another bug[2], which was fixed in zsh
version 4.3.12. After this change, 'git checkout ma<tab>' would resolve
to 'git checkout master\ '.
Aditionally, the introduction of __gitcomp_nl in commit a31e626
(completion: optimize refs completion) in git also made the problem
apparent, as Matthieu Moy reported.
The simplest and most generic solution is to hide all the changes we do
to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This
works on versions of git before and after the introduction of
__gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12.
Once zsh is fixed, we should conditionally disable this workaround to
have the same benefits as bash users.

To find out which is its parent the commit of the new branch is compared
sequentially to each blob of the parent branch from the newest to the
oldest. The first blob which results in a zero diff is considered the
parent commit. If none is found, then the commit is applied to the top
of the parent branch.
A fast-import "checkpoint" call is required because diff-tree is only
able to work with blobs on disk. But most of these commits will not be
part of the final imported tree, making fast-import fail. To avoid this,
the temporary branches are tracked and then removed at the end of the

Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there.
When the same submodule is added on a branch where it wasn't present so
far (it is not found in the .gitmodules file), the name is not initialized
from the path as it should. This leads to a wrong path entered in the
gitfile when the .git/modules/<name> directory is found, as this happily
uses the - now empty - name. It then always points only a single directory
up, even if we have a path deeper in the directory hierarchy.
Fix that by initializing the name of the submodule early in module_clone()
if module_name() returned an empty name and add a test to catch that bug.

6f48d39 (clone: delay cloning until after remote HEAD checking -
2012-01-16) allows us to perform some checks on remote refs before the
actual cloning happens. But not all transport types support
this. Remote helper with "import" capability will not return complete
ref information until fetch is performed and therefore the clone cannot
be delayed.
foreign_vcs field in struct remote was used to detect this kind of transport
and save the result. This is a mistake because foreign_vcs is designed
to override url-based transport detection. As a result, if the same
"struct transport *" object is used on many different urls and one of
them attached remote transport, the following urls will be mistakenly
attached to the same transport. This fault is worked around by dad0b3d
(push: do not let configured foreign-vcs permanently clobbered -
2012-01-23)
To fix this, detect incomplete refs from transport_get_remote_refs()
by SHA-1. Incomplete ones must have null SHA-1 (*). Then revert
changes related to foreign_cvs field in 6f48d39 and dad0b3d.
A good thing from this change is that cloning smart http transport can
also be delayed. Earlier it falls into the same category "remote
transport, no delay".
(*) Theoretically if one of the remote refs happens to have null SHA-1,
it will trigger false alarm and the clone will not be delayed. But
that chance may be too small for us to pay attention to.

Recently, 6f48d39 (clone: delay cloning until after remote HEAD checking,
2012-01-16) tried to record if a remote helper needs to be called after
parsing the remote when transport_get() is called, by overwriting the
field meant to store the configured remote helper name in the remote
structure.
This is OK when a remote represents a single remote repository, but fails
miserably when pushing to locations with multiple URLs, like this:
$ cat .git/config
[remote "origin"]
url = https://code.google.com/p/git-htmldocs/
url = github.com:gitster/git-htmldocs.git
push = refs/heads/master:refs/heads/master
$ git push
The second url that is supposed to use the git-over-ssh transport
mistakenly use https:// and fails with:
error: Couldn't resolve host 'github.com:gitster' while accessing
github.com:gitster/git-htmldocs.git/info/refs
fatal: HTTP request failed
The right solution would probably be to dedicate a separate field to store
the detected external helper to be used, which is valid only during a
single use of transport until it is disconnected, instead of overwriting
foreign_vcs field, but in the meantime, this band-aid should suffice.

Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.
After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.
Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).
There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.
Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

Starting from GNU Make 3.82 $(wildcard ...) no longer sorts the result
(from NEWS):
* WARNING: Backward-incompatibility!
Wildcards were not documented as returning sorted values, but the results
have been sorted up until this release.. If your makefiles require sorted
results from wildcard expansions, use the $(sort ...) function to request
it explicitly.
2a59dc32aa
I usually watch test progress visually, and if tests are sorted, even
with make -j4 they go more or less incrementally by their t number. On
the other side, without sorting, tests are executed in seemingly random
order even for -j1. Let's please maintain sane tests order for perceived
prettyness.
Another note is that in GNU Make sort also works as uniq, so after sort
being removed, we might expect e.g. $(wildcard *.sh a.*) to produce
duplicates for e.g. "a.sh". From this point of view, adding sort could
be seen as hardening t/Makefile from accidentally introduced dups.
It turned out that prevous releases of GNU Make did not perform full
sort in $(wildcard), only sorting results for each pattern, that's why
explicit sort-as-uniq is relevant even for older makes.

The protocol between transport-helper.c and remote-curl requires
remote-curl to always print a blank line after the push command
has run. If the blank line is ommitted, transport-helper kills its
container process (the git push the user started) with exit(128)
and no message indicating a problem, assuming the helper already
printed reasonable error text to the console.
However if the remote rejects all branches with "ng" commands in the
report-status reply, send-pack terminates with non-zero status, and
in turn remote-curl exited with non-zero status before outputting
the blank line after the helper status printed by send-pack. No
error messages reach the user.
This caused users to see the following from git push over HTTP
when the remote side's update hook rejected the branch:
$ git push http://... master
Counting objects: 4, done.
Delta compression using up to 6 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 301 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
$
Always print a blank line after the send-pack process terminates,
ensuring the helper status report (if it was output) will be
correctly parsed by the calling transport-helper.c. This ensures
the helper doesn't abort before the status report can be shown to
the user.

In a topic branch workflow, you often want to find the latest commit that
merged a side branch that touched a particular area of the system, so that
a new topic branch to work on that area can be forked from that commit.
For example, I wanted to find an appropriate fork-point to queue Luke's
changes related to git-p4 in contrib/fast-import/.
"git log --first-parent" traverses the first-parent chain, and "-m --stat"
shows the list of paths touched by commits including merge commits. We
could ask the question this way:
# What is the latest commit that touched that path?
$ git log --first-parent --oneline -m --stat master |
sed -e '/^ contrib\/fast-import\/git-p4 /q' | tail
The above finds that 8cbfc11 (Merge branch 'pw/p4-view-updates',
2012-01-06) was such a commit.
But a more natural way to spell this question is this:
$ git log --first-parent --oneline -m --stat -1 master -- \
contrib/fast-import/git-p4
Unfortunately, this does not work. It finds ecb7cf9 (git-p4: rewrite view
handling, 2012-01-02). This commit is a part of the merged topic branch
and is _not_ on the first-parent path from the 'master':
$ git show-branch 8cbfc11ecb7cf9
! [8cbfc11] Merge branch 'pw/p4-view-updates'
! [ecb7cf9] git-p4: rewrite view handling
--
- [8cbfc11] Merge branch 'pw/p4-view-updates'
+ [8cbfc11^2] git-p4: view spec documentation
++ [ecb7cf9] git-p4: rewrite view handling
The problem is caused by the merge simplification logic when it inspects
the merge commit 8cbfc11. In this case, the history leading to the tip of
'master' did not touch git-p4 since 'pw/p4-view-updates' topic forked, and
the result of the merge is simply a copy from the tip of the topic branch
in the view limited by the given pathspec. The merge simplification logic
discards the history on the mainline side of the merge, and pretends as if
the sole parent of the merge is its second parent, i.e. the tip of the
topic. While this simplification is correct in the general case, it is at
least surprising if not outright wrong when the user explicitly asked to
show the first-parent history.
Here is an attempt to fix this issue, by not allowing us to compare the
merge result with anything but the first parent when --first-parent is in
effect, to avoid the history traversal veering off to the side branch.

The pathspec structure has a few bits of data to drive various operation
modes after we unified the pathspec matching logic in various codepaths.
For example, max_depth field is there so that "git grep" can limit the
output for files found in limited depth of tree traversal. Also in order
to show just the surface level differences in "git diff-tree", recursive
field stops us from descending into deeper level of the tree structure
when it is set to false, and this also affects pathspec matching when
we have wildcards in the pathspec.
The diff-index has always wanted the recursive behaviour, and wanted to
match pathspecs without any depth limit. But we forgot to do so when we
updated tree_entry_interesting() logic to unify the pathspec matching
logic.

Keep track of how many entries at the beginning of a ref_array are already
sorted. In sort_ref_array(), return early if the the array is already
sorted (i.e., if no new references has been appended to the end of the
list since the last call to sort_ref_array()).
Sort ref_arrays only when needed, namely in search_ref_array() and in
do_for_each_ref(). However, never call sort_ref_array() on the
extra_refs, because extra_refs can contain multiple entries with the same
name and because sort_ref_array() not only sorts, but de-dups its
contents.
This change is currently not useful, because entries are not added to
ref_arrays after they are created. But in a moment they will be...
Implementation note: we could store a binary "sorted" value instead of
an integer, but storing the number of sorted entries leaves the way
open for a couple of possible future optimizations:
* In sort_ref_array(), sort *only* the unsorted entries, then merge
them with the sorted entries. This should be faster if most of the
entries are already sorted.
* Teach search_ref_array() to do a binary search of any sorted
entries, and if unsuccessful do a linear search of any unsorted
entries. This would avoid the need to sort the list every time that
search_ref_array() is called, and (given some intelligence about how
often to sort) could significantly improve the speed in certain
hypothetical usage patterns.

The credential-cache helper will try to connect to its
daemon over a unix socket. Originally, a failure to do so
was silently ignored, and we would either give up (if
performing a "get" or "erase" operation), or spawn a new
daemon (for a "store" operation).
But since 8ec6c8d, we try to report more errors. We detect a
missing daemon by checking for ENOENT on our connection
attempt. If the daemon is missing, we continue as before
(giving up or spawning a new daemon). For any other error,
we die and report the problem.
However, checking for ENOENT is not sufficient for a missing
daemon. We might also get ECONNREFUSED if a dead daemon
process left a stale socket. This generally shouldn't
happen, as the daemon cleans up after itself, but the daemon
may not always be given a chance to do so (e.g., power loss,
"kill -9").
The resulting state is annoying not just because the helper
outputs an extra useless message, but because it actually
blocks the helper from spawning a new daemon to replace the
stale socket.
Fix it by checking for ECONNREFUSED.

Revese the order of delta applying so that by the time a delta is

Current find_unresolved_deltas() links all bases together in a form of
tree, using struct base_data, with prev_base pointer to point to
parent node. Then it traverses down from parent to children in
recursive manner with all base_data allocated on stack.
To eliminate recursion, we simply need to put all on heap
(parse_pack_objects and fix_unresolved_deltas). After that, it's
simple non-recursive depth-first traversal loop. Each node also
maintains its own state (ofs and ref indices) to iterate over all
children nodes.
So we process one node:
- if it returns a new (child) node (a parent base), we link it to our
tree, then process the new node.
- if it returns nothing, the node is done, free it. We go back to
parent node and resume whatever it's doing.
and do it until we have no nodes to process.

The pathspec structure has a few bits of data to drive various operation
modes after we unified the pathspec matching logic in various codepaths.
For example, max_depth field is there so that "git grep" can limit the
output for files found in limited depth of tree traversal. Also in order
to show just the surface level differences in "git diff-tree", recursive
field stops us from descending into deeper level of the tree structure
when it is set to false, and this also affects pathspec matching when
we have wildcards in the pathspec.
The diff-index has always wanted the recursive behaviour, and wanted to
match pathspecs without any depth limit. But we forgot to do so when we

thin-pack: try harder to use preferred base objects as base
When creating a pack using objects that reside in existing packs, we try
to avoid recomputing futile delta between an object (trg) and a candidate
for its base object (src) if they are stored in the same packfile, and trg
is not recorded as a delta already. This heuristics makes sense because it
is likely that we tried to express trg as a delta based on src but it did
not produce a good delta when we created the existing pack.
As the pack heuristics prefer producing delta to remove data, and Linus's
law dictates that the size of a file grows over time, we tend to record
the newest version of the file as inflated, and older ones as delta
against it.
When creating a thin-pack to transfer recent history, it is likely that we
will try to send an object that is recorded in full, as it is newer. But
the heuristics to avoid recomputing futile delta effectively forbids us
from attempting to express such an object as a delta based on another
object. Sending an object in full is often more expensive than sending a
suboptimal delta based on other objects, and it is even more so if we
could use an object we know the receiving end already has (i.e. preferred
base object) as the delta base.
Tweak the recomputation avoidance logic, so that we do not punt on
computing delta against a preferred base object.
The effect of this change can be seen on two simulated upload-pack
workloads. The first is based on 44 reflog entries from my git.git
origin/master reflog, and represents the packs that kernel.org sent me git
updates for the past month or two. The second workload represents much
larger fetches, going from git's v1.0.0 tag to v1.1.0, then v1.1.0 to
v1.2.0, and so on.
The table below shows the average generated pack size and the average CPU
time consumed for each dataset, both before and after the patch:
dataset
| reflog | tags
---------------------------------
before | 53358 | 2750977
size after | 32398 | 2668479
change | -39% | -3%
---------------------------------
before | 0.18 | 1.12
CPU after | 0.18 | 1.15
change | +0% | +3%
This patch makes a much bigger difference for packs with a shorter slice
of history (since its effect is seen at the boundaries of the pack) though
it has some benefit even for larger packs.

the '\' line flushed the buffers, and the - and + lines were never

A proper fix would defer such markers until the end of the hunk.
However, word-diff is inherently whitespace-ignoring, so as a cheap

We use a prefix match for '\ ' to parallel the logic in

In prepare_attr_stack, we pop the old elements of the stack
(which were left from a previous lookup and may or may not
be useful to us). Our loop to do so checks that we never
reach the top of the stack. However, the code immediately
afterwards will segfault if we did actually reach the top of
the stack.
Fortunately, this is not an actual bug, since we will never
pop all of the stack elements (we will always keep the root
gitattributes, as well as the builtin ones). So the extra
check in the loop condition simply clutters the code and
makes the intent less clear. Let's get rid of it.

When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.
For example, if our stack contains gitattributes for:
foo/bar/baz
foo/bar
foo
but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.
To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.
There are two special cases to consider:
1. The top of our attr stack has the empty path. So we
must not check for '/', but rather special-case the
empty path, which always matches.
2. Typically when matching paths in this way, you would
also need to check for a full string match (i.e., the
character after is '\0'). We don't need to do so in
this case, though, because our path string is actually
just the directory component of the path to a file
(i.e., we know that it terminates with "/", because the
filename comes after that).

On many systems, the sockaddr_un.sun_path field is quite
small. Even on Linux, it is only 108 characters. A user of
the credential-cache daemon can easily surpass this,
especially if their home directory is in a deep directory
tree (since the default location expands ~/.git-credentials).
We can hack around this in the unix-socket.[ch] code by
doing a chdir() to the enclosing directory, feeding the
relative basename to the socket functions, and then
restoring the working directory.
This introduces several new possible error cases for
creating a socket, including an irrecoverable one in the
case that we can't restore the working directory. In the
case of the credential-cache code, we could perhaps get away
with simply chdir()-ing to the socket directory and never
coming back. However, I'd rather do it at the lower level
for a few reasons:
1. It keeps the hackery behind an opaque interface instead
of polluting the main program logic.
2. A hack in credential-cache won't help any unix-socket
users who come along later.
3. The chdir trickery isn't that likely to fail (basically
it's only a problem if your cwd is missing or goes away
while you're running). And because we only enable the
hack when we get a too-long name, it can only fail in
cases that would have failed under the previous code
anyway.

When we spawn a helper process, it should generally be done
and finish_command called before we exit. However, if we
exit abnormally due to an early return or a signal, the
helper may continue to run in our absence.
In the best case, this may simply be wasted CPU cycles or a
few stray messages on a terminal. But it could also mean a
process that the user thought was aborted continues to run
to completion (e.g., a push's pack-objects helper will
complete the push, even though you killed the push process).
This patch provides infrastructure for run-command to keep
track of PIDs to be killed, and clean them on signal
reception or input, just as we do with tempfiles. PIDs can
be added in two ways:
1. If NO_PTHREADS is defined, async helper processes are
automatically marked. By definition this code must be
ready to die when the parent dies, since it may be
implemented as a thread of the parent process.
2. If the run-command caller specifies the "clean_on_exit"
option. This is not the default, as there are cases
where it is OK for the child to outlive us (e.g., when
spawning a pager).
PIDs are cleared from the kill-list automatically during
wait_or_whine, which is called from finish_command and
finish_async.

When upload-pack advertises refs, it dereferences any tags
it sees, and shows the resulting sha1 to the client. It does
this by calling deref_tag. That function must load and parse
each tag object to find the sha1 of the tagged object.
However, it also ends up parsing the tagged object itself,
which is not strictly necessary for upload-pack's use.
Each tag produces two object loads (assuming it is not a
recursive tag), when it could get away with only a single
one. Dropping the second load halves the effort we spend.
The downside is that we are no longer verifying the
resulting object by loading it. In particular:
1. We never cross-check the "type" field given in the tag
object with the type of the pointed-to object. If the
tag says it points to a tag but doesn't, then we will
keep peeling and realize the error. If the tag says it
points to a non-tag but actually points to a tag, we
will stop peeling and just advertise the pointed-to
tag.
2. If we are missing the pointed-to object, we will not
realize (because we never even look it up in the object
db).
However, both of these are errors in the object database,
and both will be detected if a client actually requests the
broken objects in question. So we are simply pushing the
verification away from the advertising stage, and down to
the actual fetching stage.
On my test repo with 120K refs, this drops the time to
advertise the refs from ~3.2s to ~2.0s.

When we advertise a ref, the first thing we do is parse the
pointed-to object. This gives us two things:
1. a "struct object" we can use to store flags
2. the type of the object, so we know whether we need to
dereference it as a tag
Instead, we can just use lookup_unknown_object to get an
object struct, and then fill in just the type field using
sha1_object_info (which, in the case of packed files, can
find the information without actually inflating the object
data).
This can save time if you have a large number of refs, and
the client isn't actually going to request those refs (e.g.,
because most of them are already up-to-date).
The downside is that we are no longer verifying objects that
we advertise by fully parsing them (however, we do still
know we actually have them, because sha1_object_info must
find them to get the type). While we might fail to detect a
corrupt object here, if the client actually fetches the
object, we will parse (and verify) it then.
On a repository with 120K refs, the advertisement portion of
upload-pack goes from ~3.4s to 3.2s (the failure to speed up
more is largely due to the fact that most of these refs are
tags, which need dereferenced to find the tag destination
anyway).

The old code basically did:
generate array of SHA1s for alternate refs
for each unique SHA1 in array:
add_extra_ref(".have", sha1)
for each ref (including real refs and extra refs):
show_ref(refname, sha1)
But there is no need to stuff the alternate refs in extra_refs; we can
call show_ref() directly when iterating over the array, then handle
real refs separately. So change the code to:
generate array of SHA1s for alternate refs
for each unique SHA1 in array:
show_ref(".have", sha1)
for each ref (this now only includes real refs):
show_ref(refname, sha1)

When parse_object is called, we do the following:
1. read the object data into a buffer via read_sha1_file
2. call parse_object_buffer, which then:
a. calls the appropriate lookup_{commit,tree,blob,tag}
to either create a new "struct object", or to find
an existing one. We know the appropriate type from
the lookup in step 1.
b. calls the appropriate parse_{commit,tree,blob,tag}
to parse the buffer for the new (or existing) object
In step 2b, all of the called functions are no-ops for
object "X" if "X->object.parsed" is set. I.e., when we have
already parsed an object, we end up going to a lot of work
just to find out at a low level that there is nothing left
for us to do (and we throw away the data from read_sha1_file
unread).
We can optimize this by moving the check for "do we have an
in-memory object" from 2a before the expensive call to
read_sha1_file in step 1.
This might seem circular, since step 2a uses the type
information determined in step 1 to call the appropriate
lookup function. However, we can notice that all of the
lookup_* functions are backed by lookup_object. In other
words, all of the objects are kept in a master hash table,
and we don't actually need the type to do the "do we have
it" part of the lookup, only to do the "and create it if it
doesn't exist" part.
This can save time whenever we call parse_object on the same
sha1 twice in a single program. Some code paths already
perform this optimization manually, with either:
if (!obj->parsed)
obj = parse_object(obj->sha1);
if you already have a "struct object", or:
struct object *obj = lookup_unknown_object(sha1);
if (!obj || !obj->parsed)
obj = parse_object(sha1);
if you don't. This patch moves the optimization into
parse_object itself.
Most git operations won't notice any impact. Either they
don't parse a lot of duplicate sha1s, or the calling code
takes special care not to re-parse objects. I timed two
code paths that do benefit (there may be more, but these two
were immediately obvious and easy to time).
The first is fast-export, which calls parse_object on each
object it outputs, like this:
object = parse_object(sha1);
if (!object)
die(...);
if (object->flags & SHOWN)
return;
which means that just to realize we have already shown an
object, we will read the whole object from disk!
With this patch, my best-of-five time for "fast-export --all" on
git.git dropped from 26.3s to 21.3s.
The second case is upload-pack, which will call parse_object
for each advertised ref (because it needs to peel tags to
show "^{}" entries). This doesn't matter for most
repositories, because they don't have a lot of refs pointing
to the same objects. However, if you have a big alternates
repository with a shared object db for a number of child
repositories, then the alternates repository will have
duplicated refs representing each of its children.
For example, GitHub's alternates repository for git.git has
~120,000 refs, of which only ~3200 are unique. The time for
upload-pack to print its list of advertised refs dropped
from 3.4s to 0.76s.

one hidden by the other. The correct way of generating file link is
href(action=>"blob", hash_base=>$co{'id'},

It was $co{'hash'} (this key does not exist, and therefore this is

To have this fix applied in single place, this commit also reduces

The FETCH_HEAD refname is supposed to refer to the ref that was fetched
and should be merged. However all fetched refs are written to
.git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply
takes the first ref as the FETCH_HEAD, which is often the wrong one,
when other branches were also fetched.
The solution is to write the for-merge ref(s) to FETCH_HEAD first.
Then, unless --append is used, the FETCH_HEAD refname behaves as intended.
If the user uses --append, they presumably are doing so in order to
preserve the old FETCH_HEAD.
While we are at it, update an old example in the read-tree documentation
that implied that each entry in FETCH_HEAD only has the object name, which
is not true for quite a while.

When performing a plain "git stash" (without --patch), git-diff would fail
with "fatal: ambiguous argument 'HEAD': both revision and filename". The
output was piped into git-update-index, masking the failed exit status.
The output is now sent to a temporary file (which is cleaned up by
existing code), and the exit status is checked. The "HEAD" arg to the
git-diff invocation has been disambiguated too, of course.
In patch mode, "git stash -p" would fail harmlessly, leaving the working
dir untouched. Interactive adding is fine, but the resulting tree was
diffed with an ambiguous 'HEAD' argument.

Advice messages are by definition meant for human end-users, and prime
candidates for i18n/l10n. They tend to also be more verbose to be helpful,
and need to be longer than just one line.
Although we do not have parameterized multi-line advice messages yet, once
we do, we cannot emit such a message like this:
advise(_("Please rename %s to something else"), gostak);
advise(_("so that we can avoid distimming %s unnecessarily."), doshes);
because some translations may need to have the replacement of 'gostak' on
the second line (or 'doshes' on the first line). Some languages may even
need to use three lines in order to fit the same message within a
reasonable width.
Instead, it has to be a single advise() construct, like this:
advise(_("Please rename %s to something else\n"
"so that we can avoid distimming %s unnecessarily."),
gostak, doshes);
Update the advise() function and its existing callers to
- take a format string that can be multi-line and translatable as a
whole;
- use the string and the parameters to form a localized message; and
- show each line in the result with the localization of the "hint: ".

We use the 'read' command without -r, so that it treats '\' as an
escape character, in several places. This breaks the loop reading
refnames from git-for-each-ref in __git_refs() if there are refnames
such as "foo'bar", in which case for-each-ref helpfully quotes them as
$ git update-ref "refs/remotes/test/foo'bar" HEAD
$ git for-each-ref --shell --format="ref=%(refname:short)" "refs/remotes"
ref='test/foo'\''bar'
Interpolating the \' here will read "ref='test/foo'''bar'" instead, and
eval then chokes on the unbalanced quotes.
However, since none of the read loops _want_ to have backslashes
interpolated, it's much safer to use read -r everywhere.

e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding.,
2007-12-04) was meant to make gitweb faster by using Perl's internals
(see subsection "Messing with Perl's Internals" in Encode(3pm) manpage)
Simple benchmark confirms that (old = 00f429a, new = this version):
old new
old -- -65%
new 189% --
Unfortunately it made fallback mode of to_utf8 do not work... except
for default value 'latin1' of $fallback_encoding ('latin1' is Perl
native encoding), which is why it was not noticed for such long time.
utf8::valid(STRING) is an internal function that tests whether STRING
is in a _consistent state_ regarding UTF-8. It returns true is
well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held
as bytes (both these states are 'consistent'). For gitweb the second
option was true, as output from git commands is opened without ':utf8'
layer.
What made it work at all for STRING in 'latin1' encoding is the fact
that utf8:decode(STRING) turns on UTF-8 flag only if source string is
valid UTF-8 and contains multi-byte UTF-8 characters... and that if
string doesn't have UTF-8 flag set it is treated as in native Perl
encoding, i.e. 'latin1' / 'iso-8859-1' (unless native encoding it is
EBCDIC ;-)). It was ':utf8' layer that actually converted 'latin1'
(no UTF-8 flag == native == 'latin1) to 'utf8'.
Let's make use of the fact that utf8:decode(STRING) returns false if
STRING is invalid as UTF-8 to check whether to enable fallback mode.

The whole point of the recent update to allow "git pull $url $tagname" is
so that the integrator does not have to store the (signed) tag that is
used to convey authenticity to be recorded in the resulting merge in the
local repository's tag namespace. Asking for a merge be made with "git
pull $url tag $tagname" defeats it.
Note that the request can become ambiguous if the requestor has a branch
with the same name as the tag, but that is not a new problem limited to
pulling. I wouldn't mind if somebody wants to add disambiguation to the
find_matching_ref logic in the script as a separate patch, though.

When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.
However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.
On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.
However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref). But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.
Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.
Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).
This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

The non-streaming version of the filter counts CRLF and LF in the whole
buffer, and returns without doing anything when they match (i.e. what is
recorded in the object store already uses CRLF). This was done to help
people who added files from the DOS world before realizing they want to go
cross platform and adding .gitattributes to tell Git that they only want
CRLF in their working tree.
The streaming version of the filter does not want to read the whole thing
before starting to work, as that defeats the whole point of streaming. So
we instead check what byte follows CR whenever we see one, and add CR
before LF only when the LF does not immediately follow CR already to keep
CRLF as is.

Providing a single "-v" to "git push" currently does
nothing. Giving two flags ("git push -v -v") turns on the
first level of verbosity.
This is caused by a regression introduced in 8afd8dc (push:
support multiple levels of verbosity, 2010-02-24). Before
the series containing 8afd8dc, the verbosity handling for
fetching and pushing was completely separate. Commit bde873c
refactored the verbosity handling out of the fetch side, and
then 8afd8dc converted push to use the refactored code.
However, the fetch and push sides numbered and passed along
their verbosity levels differently. For both, a verbosity
level of "-1" meant "quiet", and "0" meant "default output".
But from there they differed.
For fetch, a verbosity level of "1" indicated to the "fetch"
program that it should make the status table slightly more
verbose, showing up-to-date entries. A verbosity level of
"2" meant that we should pass a verbose flag to the
transport; in the case of fetch-pack, this displays protocol
debugging information.
As a result, the refactored code in bde873c checks for
"verbosity >= 2", and only then passes it on to the
transport. From the transport code's perspective, a
verbosity of 0 or 1 both meant "0".
Push, on the other hand, does not show its own status table;
that is always handled by the transport layer or below
(originally send-pack itself, but these days it is done by
the transport code). So a verbosity level of 1 meant that we
should pass the verbose flag to send-pack, so that it knows
we want a verbose status table. However, once 8afd8dc
switched it to the refactored fetch code, a verbosity level
of 1 was now being ignored. Thus, you needed to
artificially bump the verbosity to 2 (via "-v -v") to have
any effect.
We can fix this by letting the transport code know about the
true verbosity level (i.e., let it distinguish level 0 or
1).
We then have to also make an adjustment to any transport
methods that assumed "verbose > 0" meant they could spew
lots of debugging information. Before, they could only get
"0" or "2", but now they will also receive "1". They need to
adjust their condition for turning on such spew from
"verbose > 0" to "verbose > 1".

general. Let's start a new "discussion" section and

2. It gave an example for --unreachable using for-each-ref
to mention all of the heads, saying that it will do "a
_lot_ of verification". This is hopelessly out-of-date,
as giving no arguments will check much more (reflogs,

Measurements by various people have shown that grepping in parallel is
not beneficial when the object store is involved. For example, with a
simple regex:
Threads | --cached case | worktree case
----------------------------------------------------------------
8 (default) | 2.88u 0.21s 0:02.94real | 0.19u 0.32s 0:00.16real
4 | 2.89u 0.29s 0:02.99real | 0.16u 0.34s 0:00.17real
2 | 2.83u 0.36s 0:02.87real | 0.18u 0.32s 0:00.26real
NO_PTHREADS | 2.16u 0.08s 0:02.25real | 0.12u 0.17s 0:00.31real
This happens because all the threads contend on read_sha1_mutex almost
all of the time. A more complex regex allows the threads to do more
work in parallel, but as Jeff King found out, the "super boost" (much
higher clock when only one core is active) feature of recent CPUs
still causes the unthreaded case to win by a large margin.
So until the pack machinery allows unthreaded access, we disable
grep's threading in all but the worktree case.

If you provide a custom rename score on the command line,
like:
git log -M50 --follow foo.c
it is completely ignored, and there is no way to --follow
with a looser rename score. Instead, let's use the same
rename score that will be used for generating diffs. This is
convenient, and mirrors what we do with the break-score.
You can see an example of it being useful in git.git:

create mode 100644 Documentation/technical/api-path-list.txt
You could have two separate rename scores, one for following
and one for diff. But almost nobody is going to want that,
and it would just be unnecessarily confusing. Besides which,
we re-use the diff results from try_to_follow_renames for
the actual diff output, which means having them as separate
scores is actively wrong. E.g., with the current code, you
get:
$ git log --oneline --diff-filter=R --name-status \
-M90 --follow git.spec.in
27dedf0 GIT 0.99.9j aka 1.0rc3
R084 git-core.spec.in git.spec.in
f85639c Rename the RPM from "git" to "git-core"
R098 git.spec.in git-core.spec.in
The first one should not be considered a rename by the -M
score we gave, but we print it anyway, since we blindly
re-use the diff information from the follow (which uses the
default score). So this could also be considered simply a
bug-fix, as with the current code "-M" is completely ignored
when using "--follow".

The "cherry-pick persists opts correctly" test in t3510
(cherry-pick-sequence) can cause some confusion, because the command
actually has two points of failure:
1. "-m 1" is specified on the command-line despite the base commit
"initial" not being a merge-commit.
2. The revision range indicates that there will be a conflict that
needs to be resolved.
Although the former error is trapped, and cherry-pick die()s with the
exit status 128, the reader may be distracted by the latter. Fix this
by changing the revision range to something that wouldn't cause a
conflict. Additionally, explicitly check the exit code in
"cherry-pick a non-merge with -m should fail" in t3502

Current implementation sees NUL as terminator. If users give a message
with NUL byte in it (e.g. editor set to save as UTF-16), the new commit
message will have NULs. However following operations (displaying or
amending a commit for example) will not keep anything after the first NUL.
Stop user right when they do this. If NUL is added by mistake, they have
their chance to fix. Otherwise, log messages will no longer be text "git
log" and friends would grok.

There wan't a way for commit_tree() to notice if the message the caller
prepared contained a NUL byte, as it did not take the length of the
message as a parameter. Use a pointer to a strbuf instead, so that we can
either choose to allow low-level plumbing commands to make commits that
contain NUL byte in its message, or forbid NUL everywhere by adding the
check in commit_tree(), in later patches.

We want to run tests in a predictable, sterile environment
so we can get repeatable results. They should take as
little input as possible from the environment outside the
test script. We already sanitize environment variables, but
leave stdin untouched. This means that scripts can
accidentally be impacted by content on stdin, or whether
stdin isatty().
Furthermore, scripts reading from stdin can be annoying to
outer loops which care about their stdin offset, like:
while read sha1; do
make test
done
A test which accidentally reads stdin would soak up all of
the rest of the input intended for the outer shell loop.
Let's redirect stdin from /dev/null, which solves both
of these problems. It won't detect tests accidentally
reading from stdin, but since doing so now gives a
deterministic result, we don't need to consider that an
error.
We'll also leave file descriptor 6 as a link to the original
stdin. Tests shouldn't need to look at this, but it can be
convenient for inserting interactive commands while
debugging tests (e.g., you could insert "bash <&6 >&3 2>&4"
to run interactive commands in the environment of the test
script).

This script uses the following idiom to start each test in a known
good state:
test_expect_success 'some commands use a pager' '
rm -f paginated.out || cleanup_fail &&
test_terminal git log &&
test -e paginated.out
'
where "cleanup_fail" is a function that prints an error message and
errors out.
That is bogus on three levels:
- Cleanup commands like "rm -f" and "test_unconfig" are designed not
to fail, so this logic would never trip.
- If they were to malfunction anyway, it is not useful to set apart
cleanup commands as a special kind of failure with a special error
message. Whichever command fails, the next step is to investigate
which command that was, for example by running tests with
"prove -e 'sh -x'", and fix it.
- Relying on left-associativity of mixed &&/|| lists makes the code
somewhat cryptic.
The fix is simple: drop the "|| cleanup_fail" in each test and the
definition of the "cleanup_fail" function so no new callers can arise.

Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.
However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).
Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and
smart-http as-is.

We don't currently test this case at all, and instead just
test the DAV mechanism over an unauthenticated push. That
isn't very realistic, as most people will want to
authenticate pushes.
Two of the tests expect_failure as they reveal bugs:
1. Pushing without a username in the URL fails to ask for
credentials when we get an HTTP 401. This has always
been the case, but it would be nice if it worked like
smart-http.
2. Pushing with a username fails to ask for the password
since 986bbc0 (http: don't always prompt for password,
2011-11-04). This is a severe regression in v1.7.8, as
authenticated push-over-DAV is now totally unusable
unless you have credentials in your .netrc.

This function was used for comparing local and remote ref
names during fetch (which makes it a candidate for "most
confusingly named function of the year").
It no longer has any callers, so let's get rid of it.
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
When we are determining the list of refs to fetch via
fetch-pack, we have two sets of refs to compare: those on
the remote side, and a "match" list of things we want to
fetch. We iterate through the remote refs alphabetically,
seeing if each one is wanted by the "match" list.
Since def88e9 (Commit first cut at "git-fetch-pack",
2005-07-04), we have used the "path_match" function to do a
suffix match, where a remote ref is considered wanted if
any of the "match" elements is a suffix of the remote
refname.
This enables callers of fetch-pack to specify unqualified
refs and have them matched up with remote refs (e.g., ask
for "A" and get remote's "refs/heads/A"). However, if you
provide a fully qualified ref, then there are corner cases
where we provide the wrong answer. For example, given a
remote with two refs:
refs/foo/refs/heads/master
refs/heads/master
asking for "refs/heads/master" will first match
"refs/foo/refs/heads/master" by the suffix rule, and we will
erroneously fetch it instead of refs/heads/master.
As it turns out, all callers of fetch_pack do provide
fully-qualified refs for the match list. There are two ways
fetch_pack can get match lists:
1. Through the transport code (i.e., via git-fetch)
2. On the command-line of git-fetch-pack
In the first case, we will always be providing the names of
fully-qualified refs from "struct ref" objects. We will have
pre-matched those ref objects already (since we have to
handle more advanced matching, like wildcard refspecs), and
are just providing a list of the refs whose objects we need.
In the second case, users could in theory be providing
non-qualified refs on the command-line. However, the
fetch-pack documentation claims that refs should be fully
qualified (and has always done so since it was written in
2005).
Let's change this path_match call to simply check for string
equality, matching what the callers of fetch_pack are
expecting.

The fetch-pack documentation is very clear that refs given
on the command line are to be full refs:
<refs>...::
The remote heads to update from. This is relative to
$GIT_DIR (e.g. "HEAD", "refs/heads/master"). When
unspecified, update from all heads the remote side has.
and this has been the case since fetch-pack was originally documented in
8b3d9dc ([PATCH] Documentation: clone/fetch/upload., 2005-07-14).
Let's follow our own documentation to set a good example,
and to avoid breaking when this restriction is enforced in
the next patch.

The get_remote_heads function reads the list of remote refs
during git protocol session. It dates all the way back to
def88e9 (Commit first cut at "git-fetch-pack", 2005-07-04).
At that time, the idea was to come up with a list of refs we
were interested in, and then filter the list as we got it
from the remote side.
Later, 1baaae5 (Make maximal use of the remote refs,
2005-10-28) stopped filtering at the get_remote_heads layer,
letting us use the non-matching refs to find common history.
As a result, all callers now simply pass an empty match
list (and any future callers will want to do the same). So
let's drop these now-useless parameters.

This assumes that your helper is capable of both storing and
retrieving credentials (some helpers may be read-only, and
they will fail these tests).

When we need to prompt the user for input interactively, we
want to access their terminal directly. We can't rely on
stdio because it may be connected to pipes or files, rather
than the terminal. Instead, we use "getpass()", because it
abstracts the idea of prompting and reading from the
terminal. However, it has some problems:
1. It never echoes the typed characters, which makes it OK
for passwords but annoying for other input (like usernames).
2. Some implementations of getpass() have an extremely
small input buffer (e.g., Solaris 8 is reported to
support only 8 characters).
3. Some implementations of getpass() will fall back to
reading from stdin (e.g., glibc). We explicitly don't
want this, because our stdin may be connected to a pipe
speaking a particular protocol, and reading will
disrupt the protocol flow (e.g., the remote-curl
helper).
4. Some implementations of getpass() turn off signals, so
that hitting "^C" on the terminal does not break out of
the password prompt. This can be a mild annoyance.
Instead, let's provide an abstract "git_terminal_prompt"
function that addresses these concerns. This patch includes
an implementation based on /dev/tty, enabled by setting
HAVE_DEV_TTY. The fallback is to use getpass() as before.

As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch. In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:
git cherry-pick foo
git read-tree -m -u HEAD; # forget that; let's try a different one
git cherry-pick bar
After the recent patch "allow single-pick in the middle of cherry-pick

traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick

When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.
This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.
Example: after encountering a conflict from running "git cherry-pick
foo bar baz":
CONFLICT (content): Merge conflict in main.c
error: could not apply f78a8d98c... bar!
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'
We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.
$ git cherry-pick --continue
[editor opens to confirm commit message]
[master 78c8a8c98] bar!

If you define SNPRINTF_RETURNS_BOGUS, we use a special
git_vsnprintf wrapper assumes that vsnprintf returns "-1"
instead of the number of characters that you would need to
store the result.
To do this, it invokes vsnprintf multiple times, growing a
heap buffer until we have enough space to hold the result.
However, this means we evaluate the va_list parameter
multiple times, which is generally a bad thing (it may be
modified by calls to vsnprintf, yielding undefined
behavior).
Instead, we must va_copy it and hand the copy to vsnprintf,
so we always have a pristine va_list.

If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.
This patch introduces a credential helper that will cache
passwords in memory for a short period of time.

When parsing a URL into a credential struct, we carefully
record each part of the URL, including the path on the
remote host, and use the result as part of the credential
context.
This had two practical implications:
1. Credential helpers which store a credential for later
access are likely to use the "path" portion as part of
the storage key. That means that a request to
https://example.com/foo.git
would not use the same credential that was stored in an
earlier request for:
https://example.com/bar.git
2. The prompt shown to the user includes all relevant
context, including the path.
In most cases, however, users will have a single password
per host. The behavior in (1) will be inconvenient, and the
prompt in (2) will be overly long.
This patch introduces a config option to toggle the
relevance of http paths. When turned on, we use the path as
before. When turned off, we drop the path component from the
context: helpers don't see it, and it does not appear in the
prompt.
This is nothing you couldn't do with a clever credential
helper at the start of your stack, like:
[credential "http://"]
helper = "!f() { grep -v ^path= ; }; f"
helper = your_real_helper
But doing this:
[credential]
useHttpPath = false
is way easier and more readable. Furthermore, since most
users will want the "off" behavior, that is the new default.
Users who want it "on" can set the variable (either for all
credentials, or just for a subset using
credential.*.useHttpPath).

Credential helpers can help users avoid having to type their
username and password over and over. However, some users may
not want a helper for their password, or they may be running
a helper which caches for a short time. In this case, it is
convenient to provide the non-secret username portion of
their credential via config.

The functionality for credential storage helpers is already
there; we just need to give the users a way to turn it on.
This patch provides a "credential.helper" configuration
variable which allows the user to provide one or more helper
strings.
Rather than simply matching credential.helper, we will also
compare URLs in subsection headings to the current context.
This means you can apply configuration to a subset of
credentials. For example:
[credential "https://example.com"]
helper = foo
would match a request for "https://example.com/foo.git", but
not one for "https://kernel.org/foo.git".
This is overkill for the "helper" variable, since users are
unlikely to want different helpers for different sites (and
since helpers run arbitrary code, they could do the matching
themselves anyway).
However, future patches will add new config variables where
this extra feature will be more useful.

This patch converts the http code to use the new credential
API, both for http authentication as well as for getting
certificate passwords.
Most of the code change is simply variable naming (the
passwords are now contained inside the credential struct)
or deletion of obsolete code (the credential code handles
URL parsing and prompting for us).
The behavior should be the same, with one exception: the
credential code will prompt with a description based on the
credential components. Therefore, the old prompt of:
Username for 'example.com':
Password for 'example.com':
now looks like:
Username for 'https://example.com/repo.git':
Password for 'https://user@example.com/repo.git':
Note that we include more information in each line,
specifically:
1. We now include the protocol. While more noisy, this is
an important part of knowing what you are accessing
(especially if you care about http vs https).
2. We include the username in the password prompt. This is
not a big deal when you have just been prompted for it,
but the username may also come from the remote's URL
(and after future patches, from configuration or
credential helpers). In that case, it's a nice
reminder of the user for which you're giving the
password.
3. We include the path component of the URL. In many
cases, the user won't care about this and it's simply
noise (i.e., they'll use the same credential for a
whole site). However, that is part of a larger
question, which is whether path components should be
part of credential context, both for prompting and for
lookup by storage helpers. That issue will be addressed
as a whole in a future patch.
Similarly, for unlocking certificates, we used to say:
Certificate Password for 'example.com':
and we now say:
Password for 'cert:///path/to/certificate':
Showing the path to the client certificate makes more sense,
as that is what you are unlocking, not "example.com".

All of the components of a credential struct can be found in
a URL. For example, the URL:
http://foo:bar@example.com/repo.git
contains:
protocol=http
host=example.com
path=repo.git
username=foo
password=bar
We want to be able to turn URLs into broken-down credential
structs so that we know two things:
1. Which parts of the username/password we still need
2. What the context of the request is (for prompting or
as a key for storing credentials).
This code is based on http_auth_init in http.c, but needed a
few modifications in order to get all of the components that
the credential object is interested in.
Once the http code is switched over to the credential API,
then http_auth_init can just go away.

There are a few places in git that need to get a username
and password credential from the user; the most notable one
is HTTP authentication for smart-http pushing.
Right now the only choices for providing credentials are to
put them plaintext into your ~/.netrc, or to have git prompt
you (either on the terminal or via an askpass program). The
former is not very secure, and the latter is not very
convenient.
Unfortunately, there is no "always best" solution for
password management. The details will depend on the tradeoff
you want between security and convenience, as well as how
git can integrate with other security systems (e.g., many
operating systems provide a keychain or password wallet for
single sign-on).
This patch provides an abstract notion of credentials as a
data item, and provides three basic operations:
- fill (i.e., acquire from external storage or from the
user)
- approve (mark a credential as "working" for further
storage)
- reject (mark a credential as "not working", so it can
be removed from storage)
These operations can be backed by external helper processes
that interact with system- or user-specific secure storage.

P4 only looks at the environment variable $PWD to figure out

One place this crops up is when using a P4CONFIG environment
variable to specify P4 parameters, such as P4USER or P4PORT.

Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.
This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.
This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.
The rest of the commit message goes into detail about various
sub-parts of this commit.
= Installation
Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.
= Perl
Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.
Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.
Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.
I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.
See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.
= Shell
Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.
If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.
If neither are present we'll use a dumb printf(1) fall-through
wrapper.
= About libcharset.h and langinfo.h
We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.
The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.
GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

When git apply is passed something that is not a patch, it does not produce
an error message or exit with a non-zero status if it was not actually
"applying" the patch i.e. --check or --numstat etc were supplied on the
command line.
Fix this by producing an error when apply fails to find any hunks whatsoever
while parsing the patch.
This will cause some of the output formats (--numstat, --diffstat, etc) to
produce an error when they formerly would have reported zero changes and
exited successfully. That seems like the correct behavior though. Failure
to recognize the input as a patch should be an error.

This extends the earlier approach to stream a large file directly from the

It is useful to be able to rewind a check-summed file to a certain
previous state after writing data into it using sha1write() API. The
fast-import command does this after streaming a blob data to the packfile
being generated and then noticing that the same blob has already been
written, and it does this with a private code truncate_pack() that is
commented as "Yes, this is a layering violation".
Introduce two API functions, sha1file_checkpoint(), that allows the caller
to save a state of a sha1file, and then later revert it to the saved state.
Use it to reimplement truncate_pack().

This fixes the bug uncovered by the tests added in the previous two patches.
When an existing notes ref was loaded into the fast-import machinery, the
num_notes counter associated with that ref remained == 0, even though the
true number of notes in the loaded ref was higher. This caused a fanout
level of 0 to be used, although the actual fanout of the tree could be > 0.
Manipulating the notes tree at an incorrect fanout level causes removals to
silently fail, and modifications of existing notes to instead produce an
additional note (leaving the old object in place at a different fanout level).
This patch fixes the bug by explicitly counting the number of notes in the
notes tree whenever it looks like the num_notes counter could be wrong (when
num_notes == 0). There may be false positives (i.e. triggering the counting
when the notes tree is truly empty), but in those cases, the counting should
not take long.

The previous patch exposed a bug in fast-import where _removing_ an existing

(subject to the same circumstances).

There is a bug in fast-import where the fanout levels of an existing notes
tree being loaded into the fast-import machinery is disregarded. Instead, any
tree loaded is assumed to have a fanout level of 0. If the true fanout level
is deeper, any attempt to remove a note from that tree will silently fail
(as the note will not be found at fanout level 0).
However, this bug was covered up by the way in which the t9301 testcase was
written: When generating the fast-import commands to test mass removal of
notes, we appended these commands to an already existing 'input' file which
happened to already contain the fast-import commands used in the previous
subtest to generate the very same notes tree. This would normally be harmless
(but suboptimal) as the notes created were identical to the notes already
present in the notes tree. But the act of repeating all the notes additions
caused the internal fast-import data structures to recalculate the fanout,
instead of hanging on to the initial (incorrect) fanout (that causes the bug
described above). Thus, the subsequent removal of notes in the same 'input'
file would succeed, thereby covering up the bug described above.
This patch creates a new 'input' file instead of appending to the file from
the previous subtest. Thus, we end up properly testing removal of notes that
were added by a previous fast-import command. As a side effect, the notes
removal can no longer refer to commits using the marks set by the previous
fast-import run, instead the commits names must be referenced directly.
The underlying fast-import bug is still present after this patch, but now we
have at least uncovered it. Therefore, the affected subtests are labeled as
expected failures until the underlying bug is fixed.

Ignored files usually are generated files (e.g. .o files) and can be
safely discarded. However sometimes users may have important files in
working directory, but still want a clean "git status", so they mark
them as ignored files. But in this case, these files should not be
overwritten without asking first.
Enable this use case with --no-overwrite-ignore, where git only sees

The "git cherry-pick --abort" command currently renames the
.git/sequencer directory to .git/sequencer-old instead of removing it
on success due to an accident. cherry-pick --abort is designed to
work in three steps:
1) find which commit to roll back to
2) call "git reset --merge <commit>" to move to that commit
3) remove the .git/sequencer directory
But the careless author forgot step 3 entirely. The only reason the
command worked anyway is that "git reset --merge <commit>" renames the
.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.
By running "git cherry-pick --abort", the operator has clearly
indicated that she is not planning to continue cherry-picking. Remove
the (renamed) .git/sequencer directory as intended all along.

When conflicts are encountered while reverting a commit, it can be

Set a REVERT_HEAD pseudoref when "git revert" does not make a commit,
for cases like this. This also makes it possible for scripts to
distinguish between a revert that encountered conflicts and other
sources of an unmerged index.

In the spirit of v1.6.3.3~3^2 (refuse to merge during a merge,

2. resolve conflicts
3. git cherry-pick HEAD..origin (instead of "git cherry-pick

Good. However, the error message on attempting step 3 is more

$ git cherry-pick HEAD..origin
error: .git/sequencer already exists.
error: A cherry-pick or revert is in progress.

hint: or --quit to forget about it

Clarify by removing the redundant first "error:" message, simplifying

becomes

The new name for "cherry-pick, please get out of my way, since I've

this is analagous to quiting a program the user is no longer using ---

Usually git is careful not to allow clients to fetch
arbitrary objects from the database; for example, objects
received via upload-pack must be reachable from a ref.
Upload-archive breaks this by feeding the client's tree-ish
directly to get_sha1, which will accept arbitrary hex sha1s,
reflogs, etc.
This is not a problem if all of your objects are publicly
reachable anyway (or at least public to anybody who can run
upload-archive). Or if you are making the repo available by
dumb protocols like http or rsync (in which case the client
can read your whole object db directly).
But for sites which allow access only through smart
protocols, clients may be able to fetch trees from commits
that exist in the server's object database but are not
referenced (e.g., because history was rewound).
This patch tightens upload-archive's lookup to use dwim_ref
rather than get_sha1. This means a remote client can only
fetch the tip of a named ref, not an arbitrary sha1 or
reflog entry.
This also restricts some legitimate requests, too:
1. Reachable non-tip commits, like:
git archive --remote=$url v1.0~5
2. Sub-trees of reachable commits, like:
git archive --remote=$url v1.7.7:Documentation
Local requests continue to use get_sha1, and are not
restricted at all.

'git merge' can be called without any arguments if merge.defaultToUpstream
is set. However, when merge.defaultToUpstream is not set, the user will be
presented the usage information as if he entered a command with a wrong
syntaxis. Ironically, the usage information confirms that no arguments are
mandatory.
This adds a proper error message telling the user why the command failed. As
a side-effect this can help the user in discovering the possibility to merge
with the upstream branch by setting merge.defaultToUpstream.

On cygwin, test number 21 of t3200-branch.sh (git branch -m q q2
without config should succeed) fails. The failure involves the
functions from path.c which parcel out internal static buffers
from the git_path() and mkpath() functions.
In particular, the rename_ref() function calls safe_create_leading\
_directories() with a filename returned by git_path("logs/%s", ref).
safe_create_leading_directories(), in turn, calls stat() on each
element of the path it is given. On cygwin, this leads to a call
to git_config() for each component of the path, since this test
explicitly removes the config file. git_config() calls mkpath(), so
on the fourth component of the path, the original buffer passed
into the function is overwritten with the config filename.
Note that this bug is specific to cygwin and it's schizophrenic
stat() functions (see commits adbc0b6, 7faee6b and 7974843). The
lack of a config file and a path with at least four elements is
also important to trigger the bug.
In order to fix the problem, we replace the call to mkpath() with
a call to mksnpath() and provide our own buffer.

In particular, the url passed to git-clone has an extra '/' given
after the 'file://' schema prefix, thus:
git clone --reference=original "file:///$(pwd)/original one
Once the prefix is removed, the remainder of the url looks something
like "//home/ramsay/git/t/...", which is then interpreted as an
network path. This then results in a "Permission denied" error, like
so:
ramsay $ ls //home
ls: cannot access //home: No such host or network path
ramsay $ ls //home/ramsay
ls: cannot access //home/ramsay: Permission denied
ramsay $

This is technically correct, in that the file is modified,
but it's friendlier to the user if we further differentiate

looks a lot like "diff --name-status", which would also make
the distinction).
Similarly, we can distinguish typechanges ("T") and

When refreshing the index, for modified (or unmerged) files we will print

The variables holding which type of message to show are named after the
plumbing messages. However, as we begin to differentiate more cases at the

Now that the COMPUTE_HEADER_DEPENDENCIES feature is turned on
automatically for compilers that support it (see v1.7.8-rc0~142^2~1,
2011-08-18), there is no easy way to force it off. For example,
setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak
just tells the makefile to treat it as undefined and run a test
command to see if the -MMD option is supported.
So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force
the feature off. The new semantics:
- "yes" means to explicitly enable the feature
- "no" means to disable it
- "auto" means to autodetect
The default is still "auto". Any value other than these three will
cause the build to error out with a descriptive message so typos and
stale settings in config.mak don't result in mysterious behavior.
Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to
yes, no, or auto (not "1"). Stop.
So now when someone using a compiler without -MMD support reports
trouble building git, you can reproduce it by running "make
COMPUTE_HEADER_DEPENDENCIES=no".

[master 8457d13] foo
1 files changed, 1 insertions(+), 0 deletions(-)
The lines of GPG detached signature are placed in a new multi-line header
field, instead of tucking the signature block at the end of the commit log
message text (similar to how signed tag is done), for multiple reasons:
- The signature won't clutter output from "git log" and friends if it is
in the extra header. If we place it at the end of the log message, we
would need to teach "git log" and friends to strip the signature block
with an option.
- Teaching new versions of "git log" and "gitk" to optionally verify and
show signatures is cleaner if we structurally know where the signature
block is (instead of scanning in the commit log message).
- The signature needs to be stripped upon various commit rewriting
operations, e.g. rebase, filter-branch, etc. They all already ignore
unknown headers, but if we place signature in the log message, all of
these tools (and third-party tools) also need to learn how a signature
block would look like.
- When we added the optional encoding header, all the tools (both in tree
and third-party) that acts on the raw commit object should have been
fixed to ignore headers they do not understand, so it is not like that
new header would be more likely to break than extra text in the commit.
A commit made with the above sample sequence would look like this:
$ git cat-file commit HEAD

Now MERGE_HEAD records the tag objects without peeling, we could record
the result of manual conflict resolution via "git commit" without losing

the commit object, and use it to store the entire contents of each signed
tag merged.
A commit header that has a multi-line payload begins with the header tag
(e.g. "mergetag" in this case), SP, the first line of payload, LF, and all
the remaining lines have a SP inserted at the beginning.
In hindsight, it would have been better to make "merge --continue" as the
way to continue from such an interrupted merge, not "commit", but this is

messages and conflict markers.
Correct this short-signtedness by redefining the field to be a pointer to
a structure "struct merge_remote_desc" that later enhancements can add
more information. Store the original objects we were told to merge in a

When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.
E.g. a signed tag "for-linus" can be created, and the integrator can run:
$ git pull git://example.com/work.git/ for-linus
This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.
Update fmt-merge-msg so that it pre-fills the merge message template with
the body (but not signature) of the tag object to help the integrator write
a better merge message, in the same spirit as the existing merge.log summary
lines.
The message that comes from GPG signature validation is also included in
the merge message template to help the integrator verify it, but they are
prefixed with "#" to make them comments.

"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote
access context, "git fetch frotz" to fetch what the other side happened to
have fetched from what it calls 'frotz' (which may not have any relation
to what we consider is 'frotz') the last time would not make much sense,
so the fetch rules table did not include "refs/remotes/%.*s/HEAD".
When the user really wants to, "git fetch $there remotes/frotz/HEAD" would
let her do so anyway, so this is not about safety or security; it merely
is about confusion avoidance and discouraging meaningless usage.
Specifically, it is _not_ about ambiguity avoidance. A name that would
become ambiguous if we use the same rules table for both fetch and local
rev-parse would be ambiguous locally at the remote side.
So for the same reason as we added rule to allow "git fetch $there v1.0"

According to the C standard size_t is always unsigned, therefore the

false.
This was raised by clang 2.9 which throws this warning when compiling

The config options core.packedGitWindowSize, core.packedGitLimit,
core.deltaBaseCacheLimit, core.bigFileThreshold, pack.windowMemory and
pack.packSizeLimit all claim to support suffixes up to and including
'g'. This implies that they should accept sizes >=2G on 64-bit
systems: certainly, specifying a size of 3g should not silently be
translated to zero or transformed into a large negative value due to
integer overflow. However, due to use of git_config_int() rather than
git_config_ulong(), that is exactly what happens:
% git config core.bigFileThreshold 2g
% git gc --aggressive # with extra debugging code to print out
# core.bigfilethreshold after parsing
bigfilethreshold: -2147483648
[...]
This is probably irrelevant for core.deltaBaseCacheLimit, but is
problematic for the other values. (It is particularly problematic for
core.packedGitLimit, which can't even be set to its default value in
the config file due to this bug.)
This fixes things for 32-bit platforms as well. They get the usual bad
config error if an overlarge value is specified, e.g.:
fatal: bad config value for 'core.bigfilethreshold' in /home/nix/.gitconfig
This is detected in all cases, even if the 32-bit platform has no size
larger than 'long'. For signed integral configuration values, we also
detect the case where the value is too large for the signed type but
not the unsigned type.

This mostly moves existing code from builtin/tag.c (for signing)
and builtin/verify-tag.c (for verifying) to a new gpg-interface.c
file to provide a more generic library interface.
- sign_buffer() takes a payload strbuf, a signature strbuf, and a signing
key, runs "gpg" to produce a detached signature for the payload, and
appends it to the signature strbuf. The contents of a signed tag that
concatenates the payload and the detached signature can be produced by
giving the same strbuf as payload and signature strbuf.
- verify_signed_buffer() takes a payload and a detached signature as
<ptr, len> pairs, and runs "gpg --verify" to see if the payload matches
the signature. It can optionally capture the output from GPG to allow
the callers to pretty-print it in a way more suitable for their
contexts.
"verify-tag" (aka "tag -v") used to save the whole tag contents as if it
is a detached signature, and fed gpg the payload part of the tag. It
relied on gpg to fail when the given tag is not signed but just is
annotated. The updated run_gpg_verify() function detects the lack of
detached signature in the input, and errors out without bothering "gpg".

When a username is already specified at the beginning of any HTTP
transaction (e.g. "git push https://user@hosting.example.com/project.git"
or "git ls-remote https://user@hosting.example.com/project.git"), the code
interactively asks for a password before calling into the libcurl library.
It is very likely that the reason why user included the username in the
URL is because the user knows that it would require authentication to
access the resource. Asking for the password upfront would save one
roundtrip to get a 401 response, getting the password and then retrying
the request. This is a reasonable optimization.
HOWEVER.
This is done even when $HOME/.netrc might have a corresponding entry to
access the site, or the site does not require authentication to access the
resource after all. But neither condition can be determined until we call
into libcurl library (we do not read and parse $HOME/.netrc ourselves). In
these cases, the user is forced to respond to the password prompt, only to
give a password that is not used in the HTTP transaction. If the password
is in $HOME/.netrc, an empty input would later let the libcurl layer to
pick up the password from there, and if the resource does not require
authentication, any input would be taken and then discarded without
getting used. It is wasteful to ask this unused information to the end
user.
Reduce the confusion by not trying to optimize for this case and always
incur roundtrip penalty. An alternative might be to document this and keep
this round-trip optimization as-is.

This commits adds to support for showing "side-by-side" style diff.
Currently you have to hand-craft the URL; navigation for selecting
diff style is to be added in the next commit.
The diff output in unified format from "git diff-tree" is reorganized to
side-by-side style chunk by chunk with format_sidebyside_diff_chunk().
This reorganization requires knowledge about diff line classification,
so format_diff_line() was renamed to process_diff_line(), and changed to
return tuple (list) consisting of class of diff line and of
HTML-formatted (but not wrapped in <div class="diff ...">...</div>) diff
line. Wrapping is now done by caller, i.e. git_patchset_body().
Gitweb uses float+margin CSS-based layout for "side by side" diff.
You can specify style of diff with "ds" ('diff_style') query
parameter. Currently supported values are 'inline' and 'sidebyside';
the default is 'inline'.
Another solution would be to use "opt" ('extra_options') for that...
though current use of it in gitweb seems to suggest that "opt" is more
about passing extra options to underlying git commands, and "git diff"
doesn't support '--side-by-side' like GNU diff does, (yet?).

Since in-memory index entries are allocated individually now, the

The code to estimate the in-memory size of the index based on its on-disk
representation is subtly wrong for certain architecture-dependent struct
layouts. Instead of fixing it, replace the code to keep the index entries
in a single large block of memory and allocate each entry separately
instead. This is both simpler and more flexible, as individual entries
can now be freed. Actually using that added flexibility is left for a
later patch.

estimate_cache_size() tries to guess how much memory is needed for the
in-memory representation of an index file. It does that by using the
file size, the number of entries and the difference of the sizes of the
on-disk and in-memory structs -- without having to check the length of
the name of each entry, which varies for each entry, but their sums are
the same no matter the representation.
Except there can be a difference. First of all, the size is really
calculated by ce_size and ondisk_ce_size based on offsetof(..., name),
not sizeof, which can be different. And entries are padded with 1 to 8
NULs at the end (after the variable name) to make their total length a
multiple of eight.
So in order to allocate enough memory to hold the index, change the
delta calculation to be based on offsetof(..., name) and round up to
the next multiple of eight.
On a 32-bit Linux, this delta was used before:
sizeof(struct cache_entry) == 72
sizeof(struct ondisk_cache_entry) == 64
---
8
The actual difference for an entry with a filename length of one was,
however (find the definitions are in cache.h):
offsetof(struct cache_entry, name) == 72
offsetof(struct ondisk_cache_entry, name) == 62
ce_size == (72 + 1 + 8) & ~7 == 80
ondisk_ce_size == (62 + 1 + 8) & ~7 == 64
---
16
So eight bytes less had been allocated for such entries. The new
formula yields the correct delta:
(72 - 62 + 7) & ~7 == 16

Rather nasty things happen when a mutex is not initialized but locked
nevertheless. Now, when we're not running in a threaded manner, the mutex
is not initialized, which is correct. But then we went and used the mutex
anyway, which -- at least on Windows -- leads to a hard crash (ordinarily
it would be called a segmentation fault, but in Windows speak it is an
access violation).
This problem was identified by our faithful tests when run in the msysGit
environment.
To avoid having to wrap the line due to the 80 column limit, we use

__git_heads() was introduced in 5de40f5 (Teach bash about
git-repo-config., 2006-11-27), and __git_tags() in 88e21dc (Teach bash
about completing arguments for git-tag, 2007-08-31). As their name
suggests, __git_heads() is supposed to list only branches, and
__git_tags() only tags.
Since their introduction both of these functions consist of two
distinct parts. The first part gets branches or tags, respectively,
from a local repositoty using 'git for-each-ref'. The second part
queries a remote repository given as argument using 'git ls-remote'.
These remote-querying parts are broken in both functions since their
introduction, because they list both branches and tags from the remote
repository. (The 'git ls-remote' query is not limited to list only
heads or tags, respectively, and the for loop filtering the query
results prints everything except dereferenced tags.) This breakage
could be easily fixed by passing the '--heads' or '--tags' options or
appropriate refs patterns to the 'git ls-remote' invocations.
However, that no one noticed this breakage yet is probably not a
coincidence: neither of these two functions were used to query a
remote repository, the remote-querying parts were dead code already
upon thier introduction and remained dead ever since.
Since those parts of code are broken, are and were never used, stop
the bit-rotting and remove them.

Refspecs for branches in a remote repository start with 'refs/heads/',
so completing those refspecs with 'git config remote.origin.fetch
<TAB>' always offers 'refs/heads/' first, because that's the unique
part of the possible refspecs. But it does so only after querying the
remote with 'git ls-remote', which can take a while when the request
goes through some slower network to a remote server.
Don't waste the user's time and offer 'refs/heads/' right away for
'git config remote.origin.fetch <TAB>'.
The reason for putting 'refs/heads/' directly into COMPREPLY instead
of using __gitcomp() is to avoid __gitcomp() adding a trailing space.

The remote-handling part of __git_refs() has a nice for loop and state
machine case statement to iterate over all words from the output of
'git ls-remote' to identify object names and ref names. Since each
line in the output of 'git ls-remote' consists of an object name and a
ref name, we can do more effective filtering by using a while-read
loop and letting bash's word splitting take care of object names.
This way the code is easier to understand and the loop will need only
half the number of iterations than before.

For a local repository the __git_refs() completion helper function
lists refs under 'refs/(tags|heads|remotes)/', plus some special refs
like HEAD and ORIG_HEAD. For a remote repository, however, it lists
all refs.
Fix this inconsistency by specifying refs filter patterns for 'git
ls-remote' to only list refs under 'refs/(tags|heads|remotes)/'.
For now this makes it impossible to complete refs outside of
'refs/(tags|heads|remotes)/' in a remote repository, but a followup
patch will resurrect that.

After a unique command or option is completed, in most cases it is a
good thing to add a trailing a space, but sometimes it doesn't make
sense, e.g. when the completed word is an option taking an argument
('--option=') or a configuration section ('core.'). Therefore the
completion script uses the '-o nospace' option to prevent bash from
automatically appending a space to unique completions, and it has the
__gitcomp() function to add that trailing space only when necessary.
See 72e5e989 (bash: Add space after unique command name is completed.,
2007-02-04), 78d4d6a2 (bash: Support unique completion on git-config.,
2007-02-04), and b3391775 (bash: Support unique completion when
possible., 2007-02-04).
__gitcomp() therefore iterates over all possible completion words it
got as argument, and checks each word whether a trailing space is
necessary or not. This is ok for commands, options, etc., i.e. when
the number of words is relatively small, but can be noticeably slow
for large number of refs. However, while options might or might not
need that trailing space, refs are always handled uniformly and always
get that trailing space (or a trailing '.' for 'git config
branch.<head>.'). Since refs listed by __git_refs() & co. are
separated by newline, this allows us some optimizations with
'compgen'.
So, add a specialized variant of __gitcomp() that only deals with
possible completion words separated by a newline and uniformly appends
the trailing space to all words using 'compgen -S " "' (or any other
suffix, if specified), so no iteration over all words is needed. But
we need to fiddle with IFS, because the default IFS containing a space
would cause the added space suffix to be stripped off when compgen's
output is stored in the COMPREPLY array. Therefore we use only
newline as IFS, hence the requirement for the newline-separated
possible completion words.
Convert all callsites of __gitcomp() where it's called with refs, i.e.
when it gets the output of either __git_refs(), __git_heads(),
__git_tags(), __git_refs2(), __git_refs_remotes(), or the odd 'git
for-each-ref' somewhere in _git_config(). Also convert callsites
where it gets other uniformly handled newline separated word lists,
i.e. either remotes from __git_remotes(), names of set configuration
variables from __git_config_get_set_variables(), stashes, or commands.
Here are some timing results for dealing with 10000 refs.
Before:
$ refs="$(__git_refs ~/tmp/git/repo-with-10k-refs/)"
$ time __gitcomp "$refs"

This brings back some of the performance lost in optimizing recency
order inside pack objects. We were doing extreme amounts of object
re-traversal: for the 2.14 million objects in the Linux kernel
repository, we were calling add_to_write_order() over 1.03 billion times
(a 0.2% hit rate, making 99.8% of of these calls extraneous).
Two optimizations take place here- we can start our objects array
iteration from a known point where we left off before we started trying
to find our tags, and we don't need to do the deep dives required by
add_family_to_write_order() if the object has already been marked as
filled.

629cd3a (resolve_ref(): emit warnings for improperly-formatted references,
2011-09-15) made resolve_ref() warn against files that are found in the
directories the ref dwimmery looks at. The intent may be good, but these
messages come from a wrong level of the API hierarchy.
Instead record the breakage in "flags" whose purpose is to explain the
result of the function to the caller, who is in a much better position to
make intelligent decision based on the information.
This updates sha1_name.c::dwim_ref() to warn against such a broken
candidate only when it does not appear directly below $GIT_DIR to restore
the traditional behaviour, as we know many files directly underneath
$GIT_DIR/ are not refs.
Warning against "git show config --" with "$GIT_DIR/config does not look

One of the filetypes that p4 supports is utf16. Its behavior is
odd in this case. The data delivered through "p4 -G print" is
not encoded in utf16, although "p4 print -o" will produce the
proper utf16-encoded file.
When dealing with this filetype, discard the data from -G, and
instead read the contents directly.
An alternate approach would be to try to encode the data in
python. That worked for true utf16 files, but for other files
marked as utf16, p4 delivers mangled text in no recognizable encoding.
Add a test case to check utf16 handling, and +k and +ko handling.

The http_init function takes a "struct remote". Part of its
initialization procedure is to look at the remote's url and
grab some auth-related parameters. However, using the url
included in the remote is:
- wrong; the remote-curl helper may have a separate,
unrelated URL (e.g., from remote.*.pushurl). Looking at
the remote's configured url is incorrect.
- incomplete; http-fetch doesn't have a remote, so passes
NULL. So http_init never gets to see the URL we are
actually going to use.
- cumbersome; http-push has a similar problem to
http-fetch, but actually builds a fake remote just to

cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30) broke
the expansion of aliases.
This was caused by treating %config_path_settings, newly introduced in
said patch, like %config_bool_settings instead of like %config_settings.
Copy from %config_settings, making it more readable.
While at it add basic test for expansion of aliases, and for path
expansion, which would catch this error.
Nb. there were a few issues that were responsible for this error:
1. %config_bool_settings and %config_settings despite similar name have
different semantic.
%config_bool_settings values are arrays where the first element is
(reference to) the variable to set, and second element is default
value... which admittedly is a bit cryptic. More readable if more
verbose option would be to use hash reference, e.g.:
my %config_bool_settings = (
"thread" => { variable => \$thread, default => 1},
[...]
%config_settings values are either either reference to scalar variable
or reference to array. In second case it means that option (or config
option) is multi-valued. BTW. this is similar to what Getopt::Long does.
2. In cec5dae (use new Git::config_path() for aliasesfile, 2011-09-30)
the setting "aliasesfile" was moved from %config_settings to newly
introduced %config_path_settings. But the loop that parses settings
from %config_path_settings was copy'n'pasted *wrongly* from
%config_bool_settings instead of from %config_settings.
It looks like cec5dae author cargo-culted this change...

These can happen if another process simultaneously prunes a
pack. But that is not usually an error condition, because a
properly-running prune should have repacked the object into
a new pack. So we will notice that the pack has disappeared
unexpectedly, print a message, try other packs (possibly
after re-scanning the list of packs), and find it in the new
pack.

It's possible that while pack-objects is running, a
simultaneously running prune process might delete a pack
that we are interested in. Because we load the pack indices
early on, we know that the pack contains our item, but by
the time we try to open and map it, it is gone.
Since c715f78, we already protect against this in the normal
object access code path, but pack-objects accesses the packs
at a lower level. In the normal access path, we call
find_pack_entry, which will call find_pack_entry_one on each
pack index, which does the actual lookup. If it gets a hit,
we will actually open and verify the validity of the
matching packfile (using c715f78's is_pack_valid). If we
can't open it, we'll issue a warning and pretend that we
didn't find it, causing us to go on to the next pack (or on
to loose objects).
Furthermore, we will cache the descriptor to the opened
packfile. Which means that later, when we actually try to
access the object, we are likely to still have that packfile
opened, and won't care if it has been unlinked from the
filesystem.
Notice the "likely" above. If there is another pack access
in the interim, and we run out of descriptors, we could
close the pack. And then a later attempt to access the
closed pack could fail (we'll try to re-open it, of course,
but it may have been deleted). In practice, this doesn't
happen because we tend to look up items and then access them
immediately.
Pack-objects does not follow this code path. Instead, it
accesses the packs at a much lower level, using
find_pack_entry_one directly. This means we skip the
is_pack_valid check, and may end up with the name of a
packfile, but no open descriptor.
We can add the same is_pack_valid check here. Unfortunately,
the access patterns of pack-objects are not quite as nice
for keeping lookup and object access together. We look up
each object as we find out about it, and the only later when
writing the packfile do we necessarily access it. Which
means that the opened packfile may be closed in the interim.
In practice, however, adding this check still has value, for
three reasons.
1. If you have a reasonable number of packs and/or a
reasonable file descriptor limit, you can keep all of
your packs open simultaneously. If this is the case,
then the race is impossible to trigger.
2. Even if you can't keep all packs open at once, you
may end up keeping the deleted one open (i.e., you may
get lucky).
3. The race window is shortened. You may notice early that
the pack is gone, and not try to access it. Triggering
the problem without this check means deleting the pack
any time after we read the list of index files, but
before we access the looked-up objects. Triggering it
with this check means deleting the pack means deleting
the pack after we do a lookup (and successfully access
the packfile), but before we access the object. Which
is a smaller window.

You can't currently run git-pull or git-rebase from outside
of the work tree, even with GIT_WORK_TREE set, due to an
overeager require_work_tree function. Commit e2eb527
documents this problem and provides the infrastructure for a
fix, but left it to later commits to audit and update
individual scripts.
Changing these scripts to use require_work_tree_exists is
easy to verify. We immediately call cd_to_toplevel, anyway.
Therefore no matter which function we use, the state
afterwards is one of:
1. We have a work tree, and we are at the top level.
2. We don't have a work tree, and we have died.
The only catch is that we must also make sure no code that
ran before the cd_to_toplevel assumed that we were already
in the working tree.
In this case, we will only have included shell libraries and
called set_reflog_action, neither of which care about the
current working directory at all.

We should be able to ask for a config value both by its

well as by random mixed-case (which will be canonicalized by
git-config for us).
Subsections are a tricky point, though. Since we have both
[section "Foo"]
and
[section.Foo]
you might want git-config to canonicalize the subsection or
not, depending on which you are expecting. But there's no
way to communicate this; git-config sees only the key, and
doesn't know which type of section name will be in the
config file.
So it must leave the subsection intact, and it is up to the
caller to provide a canonical version of the subsection if
they want to match the latter form.

a gitfile cannot be larger than PATH_MAX or smaller than 10 bytes (as
its contents is "gitdir: " followed by a path) and returned early.
But it returned with a wrong value. It should have said "this cannot
possibly be a gitfile" by returning 0, but it returned 1 instead. Our
test cases do not cover this, as the bundle files produced are smaller
than PATH_MAX, except on Windows.
While at it, fix the faulty logic that the path stored in a gitfile cannot
be larger than PATH_MAX-sizeof("gitdir: ").

When core.ignorecase is true, the file globs configured in the
.gitattributes file should be matched case-insensitively against the paths
in the working directory. Let's do so.
Plus, add some tests.
The last set of tests is performed only on a case-insensitive filesystem.
Those tests make sure that git handles the case where the .gitignore file
resides in a subdirectory and the user supplies a path that does not match
the case in the filesystem. In that case^H^H^H^Hsituation, part of the
path supplied by the user is effectively interpreted case-insensitively,
and part of it is dependent on the setting of core.ignorecase. git will
currently only match the portion of the path below the directory holding
the .gitignore file according to the setting of core.ignorecase.
This is also partly future-proofing. Currently, git builds the attr stack
based on the path supplied by the user, so we don't have to do anything
special (like use strcmp_icase) to handle the parts of that path that don't
match the filesystem with respect to case. If git instead built the attr
stack by scanning the repository, then the paths in the origin field would
not necessarily match the paths supplied by the user. If someone makes a
change like that in the future, these tests will notice.

Add the option -W/--function-context to git diff. It is similar to
the same option of git grep and expands the context of change hunks
so that the whole surrounding function is shown. This "natural"
context can allow changes to be understood better.
Note: GNU patch doesn't like diffs generated with the new option;
it seems to expect context lines to be the same before and after
changes. git apply doesn't complain.
This implementation has the same shortcoming as the one in grep,
namely that there is no way to explicitly find the end of a
function. That means that a few lines of extra context are shown,
right up to the next recognized function begins. It's already
useful in its current form, though.
The function get_func_line() in xdiff/xemit.c is extended to work
forward as well as backward to find post-context as well as
pre-context. It returns the position of the first found matching
line. The func_line parameter is made optional, as we don't need
it for -W.
The enhanced function is then used in xdl_emit_diff() to extend
the context as needed. If the added context overlaps with the
next change, it is merged into the current hunk.

read_packed_refs(FILE*, struct cached_refs *cached_refs) {

Ever since mergetool--lib was split into multiple files in
v1.7.7-rc0~3^2~1 (2011-08-18), the Makefile takes care to reset umask
and use tar --no-owner when installing merge tool definitions to
$(gitexecdir)/mergetools/. Unfortunately it does not take into
account the possibility that the permission bits of the files being
copied might already be wrong.
Rather than fixing the "tar" incantation and making it even more
complicated, let's just use the "install" utility. This only means
losing the ability to install executables and subdirectories of
mergetools/, which wasn't used.

usual "hjkl = left, down, up, right" bindings used by less, vi, rogue,
and many other programs, it used "ijkl = up, left, down, right" to
mimic the inverted-T formation of the arrow keys on a qwerty keyboard,
in the style of Lode runner. So using 'j' and 'k' to scroll through
commits produces utterly confusing results to the vi user, as 'k'
moves down and 'j' moves to the previous commit.
Luckily most non-vi-users are probably using an alternate set of keys
(cursor keys or z/x + n/p) anyway. Switch to the expected vi/nethack

When core.ignorecase is turned on and there are stale index
entries, "git commit" can sometimes report directories as
untracked, even though they contain tracked files.
You can see an example of this with:
# make a case-insensitive repo
git init repo && cd repo &&
git config core.ignorecase true &&
# with some tracked files in a subdir
mkdir subdir &&
> subdir/one &&
> subdir/two &&
git add . &&
git commit -m base &&
# now make the index entries stale
touch subdir/* &&
# and then ask commit to update those entries and show
# us the status template
git commit -a
which will report "subdir/" as untracked, even though it
clearly contains two tracked files. What is happening in the
commit program is this:
1. We load the index, and for each entry, insert it into the index's
name_hash. In addition, if ignorecase is turned on, we make an
entry in the name_hash for the directory (e.g., "contrib/"), which
uses the following code from 5102c61's hash_index_entry_directories:
hash = hash_name(ce->name, ptr - ce->name);
if (!lookup_hash(hash, &istate->name_hash)) {
pos = insert_hash(hash, &istate->name_hash);
if (pos) {
ce->next = *pos;
*pos = ce;
}
}
Note that we only add the directory entry if there is not already an
entry.
2. We run add_files_to_cache, which gets updated information for each
cache entry. It helpfully inserts this information into the cache,
which calls replace_index_entry. This in turn calls
remove_name_hash() on the old entry, and add_name_hash() on the new
one. But remove_name_hash doesn't actually remove from the hash, it
only marks it as "no longer interesting" (from cache.h):
/*
* We don't actually *remove* it, we can just mark it invalid so that
* we won't find it in lookups.
*
* Not only would we have to search the lists (simple enough), but
* we'd also have to rehash other hash buckets in case this makes the
* hash bucket empty (common). So it's much better to just mark
* it.
*/
static inline void remove_name_hash(struct cache_entry *ce)
{
ce->ce_flags |= CE_UNHASHED;
}
This is OK in the specific-file case, since the entries in the hash
form a linked list, and we can just skip the "not here anymore"
entries during lookup.
But for the directory hash entry, we will _not_ write a new entry,
because there is already one there: the old one that is actually no
longer interesting!
3. While traversing the directories, we end up in the
directory_exists_in_index_icase function to see if a directory is
interesting. This in turn checks index_name_exists, which will
look up the directory in the index's name_hash. We see the old,
deleted record, and assume there is nothing interesting. The
directory gets marked as untracked, even though there are index
entries in it.
The problem is in the code I showed above:
hash = hash_name(ce->name, ptr - ce->name);
if (!lookup_hash(hash, &istate->name_hash)) {
pos = insert_hash(hash, &istate->name_hash);
if (pos) {
ce->next = *pos;
*pos = ce;
}
}
Having a single cache entry that represents the directory is
not enough; that entry may go away if the index is changed.
It may be tempting to say that the problem is in our removal
method; if we removed the entry entirely instead of simply
marking it as "not here anymore", then we would know we need
to insert a new entry. But that only covers this particular
case of remove-replace. In the more general case, consider
something like this:
1. We add "foo/bar" and "foo/baz" to the index. Each gets
their own entry in name_hash, plus we make a "foo/"
entry that points to "foo/bar".
2. We remove the "foo/bar" entry from the index, and from
the name_hash.
3. We ask if "foo/" exists, and see no entry, even though
"foo/baz" exists.
So we need that directory entry to have the list of _all_
cache entries that indicate that the directory is tracked.
So that implies making a linked list as we do for other
entries, like:
hash = hash_name(ce->name, ptr - ce->name);
pos = insert_hash(hash, &istate->name_hash);
if (pos) {
ce->next = *pos;
*pos = ce;
}
But that's not right either. In fact, it shows a second bug
in the current code, which is that the "ce->next" pointer is
supposed to be linking entries for a specific filename
entry, but here we are overwriting it for the directory
entry. So the same cache entry ends up in two linked lists,
but they share the same "next" pointer.
As it turns out, this second bug can't be triggered in the
current code. The "if (pos)" conditional is totally dead
code; pos will only be non-NULL if there was an existing
hash entry, and we already checked that there wasn't one
through our call to lookup_hash.
But fixing the first bug means taking out that call to
lookup_hash, which is going to activate the buggy dead code,
and we'll end up splicing the two linked lists together.
So we need to have a separate next pointer for the list in
the directory bucket, and we need to traverse that list in
index_name_exists when we are looking up a directory.
This bloats "struct cache_entry" by a few bytes. Which is
annoying, because it's only necessary when core.ignorecase
is enabled. There's not an easy way around it, short of
separating out the "next" pointers from cache_entry entirely
(i.e., having a separate "cache_entry_list" struct that gets
stored in the name_hash). In practice, it probably doesn't
matter; we have thousands of cache entries, compared to the
millions of objects (where adding 4 bytes to the struct
actually does impact performance).

This code calls git_config from a helper function to parse the config entry
it is interested in. Calling git_config in this way may cause a problem if
the helper function can be called after a previous call to git_config by
another function since the second call to git_config may reset some
variable to the value in the config file which was previously overridden.
The above is not a problem in this case since the function passed to
git_config only parses one config entry and the variable it sets is not
assigned outside of the parsing function. But a programmer who desires
all of the standard config options to be parsed may be tempted to modify
git_attr_config() so that it falls back to git_default_config() and then it
_would_ be vulnerable to the above described behavior.
So, move the call to git_config up into the top-level cmd_* function and
move the responsibility for parsing core.attributesfile into the main
config file parser.

This code sequence performs a strcpy into the buf member of a strbuf
struct. The strcpy may move the position of the terminating nul of the

match the len member of the strbuf struct.
Currently, this sequence works since the strbuf was given a hint when it
was initialized to allocate enough space to accomodate the string that will
be strcpy'ed, but this is an implementation detail of strbufs, not a
guarantee.
So, lets rework this sequence so that the strbuf is only manipulated by

Since much of the infrastructure does not work correctly with
unnormalized refnames, change check_refname_format() to reject them.
Similarly, change "git check-ref-format" to reject unnormalized
refnames by default. But add an option --normalize, which causes "git
check-ref-format" to normalize the refname before checking its format,
and print the normalized refname. This is exactly the behavior of the
old --print option, which is retained but deprecated.

Change check_ref_format() to take a flags argument that indicates what
is acceptable in the reference name (analogous to "git

is more convenient for callers and also fixes a failure in the test
suite (and likely elsewhere in the code) by enabling "onelevel" and
"refspec-pattern" to be allowed independently of each other.
Also rename check_ref_format() to check_refname_format() to make it

Previously most bad characters were indicated by returning 1, but "*"
was special-cased to return 2 instead of 1. One caller examined the
return value to see whether the special case occurred.
But it is easier (to document and understand) for bad_ref_char()
simply to return a boolean value, treating "*" like any other bad
character. Special-case the handling of "*" (which only occurs in
very specific circumstances) at the caller. The resulting calling
code thereby also becomes more transparent.

Also add tests of the new options. (Actually, one big reason to add
the new options is to make it easy to test check_ref_format(), though
the options should also be useful to other scripts.)
Interpret the result of check_ref_format() based on which types of
refnames are allowed. However, because check_ref_format() can only
return a single value, one test case is still broken. Specifically,
the case "git check-ref-format --onelevel '*'" incorrectly succeeds
because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this
refname even though the refname is also CHECK_REF_FORMAT_WILDCARD.
The type of check that leads to this failure is used elsewhere in
"real" code and could lead to bugs; it will be fixed over the next few
commits.

Previously, get_sha1_hex() would read one character past the end of a
null-terminated string whose strlen was an even number less than 40.
Although the function correctly returned -1 in these cases, the extra

unallocated) memory.
Add a check to avoid reading past the end of a string.

By default, when working with "--no-index" option, "grep" does not pay

can be used to tell the command to use .gitignore and stop reporting hits
from files that would be ignored. Also, when working without "--no-index",

The g+s bit on directories to make group ownership inherited is a
SysVism --- BSD and most of its descendants do not need it since they
do the sane thing by default without g+s. In fact, on some
filesystems (but not all --- tmpfs works this way but UFS does not),
the kernel of FreeBSD does not even allow non-root users to set setgid
bit on directories and produces errors when one tries:
$ git init --shared dir
fatal: Could not make /tmp/dir/.git/refs writable by group
Since the setgid bit would only mean "do what you were going to do
already", it's better to avoid setting it. Accordingly, ever since
v1.5.5-rc0~59^2 (Do not use GUID on dir in git init --share=all on
FreeBSD, 2008-03-05), git on true FreeBSD has done exactly that. Set
DIR_HAS_BSD_GROUP_SEMANTICS in the makefile for GNU/kFreeBSD, too, so
machines that use glibc with the kernel of FreeBSD get the same fix.
This fixes t0001-init.sh and t1301-shared-repo.sh on GNU/kFreeBSD
when running tests with --root pointing to a directory that uses
tmpfs.

Before falling back to gethostname(), check /etc/mailname if
GIT_AUTHOR_EMAIL is not set in the environment or through config
files. Only fall back if /etc/mailname cannot be opened or read.
The /etc/mailname convention comes from Debian policy section 11.6
("mail transport, delivery and user agents"), though maybe it could be
useful sometimes on other machines, too. The lack of this support was
noticed by various people in different ways:
- Ian observed that git was choosing the address
'ian@anarres.relativity.greenend.org.uk' rather than
'ian@davenant.greenend.org.uk' as it should have done.
- Jonathan noticed that operations like "git commit" were needlessly
slow when using a resolver that was slow to handle reverse DNS
lookups.
Alas, after this patch, if /etc/mailname is set up and the [user] name
and email configuration aren't, the committer email will not provide a
charming reminder of which machine commits were made on any more. But
I think it's worth it.
Mechanics: the functionality of reading mailname goes in its own
function, so people who care about other distros can easily add an
implementation to a similar location without making copy_email() too
long and losing clarity. While at it, we split out the fallback
default logic that does gethostname(), too (rearranging it a little
and adding a check for errors from gethostname while at it).

When a push specifies deletion of non-existent refs, the post post-receive and
post-update hooks receive them as input/arguments.
For instance, for the following push, where refs/heads/nonexistent is a ref
which does not exist on the remote side:
git push origin :refs/heads/nonexistent
the post-receive hook receives from standard input:
<null-sha1> SP <null-sha1> SP refs/heads/nonexistent
and the post-update hook receives as arguments:
refs/heads/nonexistent
which does not make sense since it is a no-op.
Teach receive-pack not to pass non-existent refs to the post-receive and
post-update hooks. If the push only attempts to delete non-existent refs,
these hooks are not even called.
The update and pre-receive hooks are still notified about attempted
deletion of non-existent refs to give them a chance to inspect the
situation and act on it.

Checking paths out of a tree is (currently) defined to do:
- Grab the paths from the named tree that match the given pathspec,
and add them to the index;
- Check out the contents from the index for paths that match the
pathspec to the working tree; and while at it
- If the given pathspec did not match anything, suspect a typo from the
command line and error out without updating the index nor the working
tree.
Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running
$ git checkout other dir
would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.
Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

git send-email was not authenticating properly when communicating over

The problem (only?) exists when libauthen-sasl-cyrus-perl

In the case of a wide breadth top-level tree (~2400 entries, all trees
in this case), we can see a noticeable cost in the profiler calling
strncmp() here. Most of the time we are at the base level of the
repository, so base is "" and baselen == 0, which means we will always
test true. Break out this one tiny case so we can short circuit the
strncmp() call.
Test cases are as follows. packages.git is the Arch Linux git-svn clone
of the packages repository which has the characteristics above.
Commands:
[1] packages.git, /usr/bin/time git log >/dev/null
[2] packages.git, /usr/bin/time git log -- autogen/trunk pacman/trunk wget/trunk >/dev/null

for a certain style of repository and operation where it nets a 6.5%
measured improvement. The other changes are likely not significant by
reasonable statistics methods.
Note: the measured improvement when originally submitted was ~11% (43 to

The list variable (which is OPT_BOOLEAN) is initialized to 0 and only
checked against 0 in the code, so it is safe to use OPT_BOOL().
The worktree_attributes variable (which is OPT_BOOLEAN) is initialized to
0 and later assigned to a field with the same name in struct archive_args,
which is a bitfield of width 1. It is safe and even more correct to use
OPT_BOOL() here; the new test in 5001 demonstrates why using OPT_COUNTUP
is wrong.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
It is natural to expect that an option defined with OPT_BOOLEAN() could be
used in this way:
int option = -1; /* unspecified */
struct option options[] = {
OPT_BOOLEAN(0, "option", &option, "set option"),
OPT_END()
};
parse_options(ac, av, prefix, options, usage, 0);
if (option < 0)
... do the default thing ...
else if (!option)
... --no-option was given ...
else
... --option was given ...
to easily tell three cases apart:
- There is no mention of the `--option` on the command line;
- The variable is positively set with `--option`; or
- The variable is explicitly negated with `--no-option`.
Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable
every time `--option` is given, and resets it to zero when `--no-option`
is given.
As a first step to remedy this, introduce a true boolean OPT_BOOL(), and
rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN
and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and
OPTION_COUNTUP respectively.
This is what db7244b (parse-options new features., 2007-11-07) from four
years ago started by marking OPTION_BOOLEAN as "INCR would have been a
better name".
Some existing users do depend on the count-up semantics; for example,
users of OPT__VERBOSE() could use it to raise the verbosity level with
repeated use of `-v` on the command line, but they probably should be
rewritten to use OPT__VERBOSITY() instead these days. I suspect that some
users of OPT__FORCE() may also use it to implement different level of
forcibleness but I didn't check.
On top of this patch, here are the remaining clean-up tasks that other
people can help:
- Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the
value that is set to the underlying variable, and if it can proven that
the variable is only used as a boolean, replace it with OPT_BOOL(). If
the caller does depend on the count-up semantics, replace it with
OPT_COUNTUP() instead.
- Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to
set 1 to the variable for a true boolean, and otherwise replace it with
OPTION_COUNTUP.
- Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if
they can be replaced with OPT__VERBOSITY().
I'll follow this message up with a separate patch as an example.

The fixLinks() function adds 'js=1' to each link that does not already
have 'js' query parameter specified. This is used to signal to gitweb
that the browser can actually do javascript when these links are used.
There are two problems with the existing code:
1. URIs with fragment and 'js' query parameter, like e.g.
...foo?js=0#l199
were not recognized as having 'js' query parameter already.
2. The 'js' query parameter, in the form of either '?js=1' or ';js=1'
was appended at the end of URI, even if it included a fragment
(had a hash part). This lead to the incorrect links like this
...foo#l199?js=1
instead of adding query parameter as last part of query, but
before the fragment part, i.e.
...foo?js=1#l199

get_ref_dir is called recursively for subdirectories, which means that
we were calling sort_ref_list for each directory of refs instead of
once for all the refs. This is a massive wast of processing, so now
just call sort_ref_list on the result of the top-level get_ref_dir, so
that the sort is only done once.
In the common case of only a few different directories of refs the
difference isn't very noticable, but it becomes very noticeable when
you have a large number of direcotries containing refs (e.g. as
created by Gerrit).

The negation example uses '*' to match everything. This used to work
before 9037026 (unpack-trees: fix sparse checkout's "unable to match
directories") because back then, the list of paths is used to match
sparse patterns, so with the patterns
*
!subdir/
subdir/ always matches any path that start with subdir/ and "*" has no
chance to get tested. The result is subdir is excluded.
After the said commit, a tree structure is dynamically created and
sparse pattern matching now follows closely how read_directory()
applies .gitignore. This solves one problem, but reveals another one.
With this new strategy, "!subdir/" rule will be only tested once when
"subdir" directory is examined. Entries inside subdir, when examined,
will match "*" and are (correctly) re-added again because any rules
without a slash will match at every directory level. In the end, "*"
can revert every negation rules.
In order to correctly exclude subdir, we must use
/*
!subdir
to limit "match all" rule at top level only.
"*" rule has no actual use in sparse checkout and can be confusing to
users. While we can automatically turn "*" to "/*", this violates
.gitignore definition. Instead, discourage "*" in favor of "/*" (in
the second example).

rev-list: Demonstrate breakage with --ancestry-path --all
The description of .git/info/sparse-checkout and
skip-worktree is exactly the opposite of what is true, which is:
If a file matches a pattern in sparse-checkout, then (it is to be
checked out and therefore) skip-worktree is unset for that file;
otherwise, it is set (so that it is not checked out).
Currently, the opposite is documented, and (consistently) read-tree's
behavior with respect to bit flips is descibed incorrectly.
Fix it.
In hindsight, it would have been much better to have a "sparse-ignore"
or "sparse-skip" file so that an empty file would mean a full checkout,
and the file logic would be analogous to that of .gitignore, excludes
and skip-worktree.

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

The current code, as is, passes control characters, such as form-feed
(^L) to highlight which then passes it through to the browser. User
agents (web browsers) that support 'application/xhtml+xml' usually
require that web pages declared as XHTML and with this mimetype are
well-formed XML. Unescaped control characters cannot appear within a
contents of a valid XML document.
This will cause the browser to display one of the following warnings:
* Safari v5.1 (6534.50) & Google Chrome v13.0.782.112:
This page contains the following errors:

Both errors were generated by gitweb.perl v1.7.3.4 w/ highlight 2.7
using arch/ia64/kernel/unwind.c from the Linux kernel.
When syntax highlighter is not used, control characters are replaced
by esc_html(), but with syntax highlighter they were passed through to
browser (to_utf8() doesn't remove control characters).
Introduce sanitize() subroutine which strips forbidden characters, but
does not perform HTML escaping, and use it in git_blob() to sanitize
syntax highlighter output for XHTML.
Note that excluding "\t" (U+0009), "\n" (U+000A) and "\r" (U+000D) is
not strictly necessary, atleast for currently the only callsite: "\t"
tabs are replaced by spaces by untabify(), "\n" is stripped from each

improvement.

The submodule code recently grew generic code to build a
dynamic argv array. Many other parts of the code can reuse
this, too, so let's make it generically available.
There are two enhancements not found in the original code:
1. We now handle the NULL-termination invariant properly,
even when no strings have been pushed (before, you
could have an empty, NULL argv). This was not a problem
for the submodule code, which always pushed at least
one argument, but was not sufficiently safe for
generic code.
2. There is a formatted variant of the "push" function.
This is a convenience function which was not needed by
the submodule code, but will make it easier to port

This patch uses test_path_is_file and test_path_is_missing
instead of "test -f / ! test -f" checks. The former are more
verbose in case of failure and more precise (e.g., is_missing
will check that the entry is actually missing, not just not
a regular file).
As a bonus, this also fixes a few buggy tests that used
"test foo" instead of "test -f foo", and consequently always
reported success.

Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.
In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.
In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.
This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

Recent versions of git can be slow to fetch repositories with a
large number of refs (or when they already have a large
number of refs). For example, GitHub makes pull-requests
available as refs, which can lead to a large number of
available refs. This slowness goes away when submodule
recursion is turned off:
$ git ls-remote git://github.com/rails/rails.git | wc -l
3034
[this takes ~10 seconds of CPU time to complete]
git fetch --recurse-submodules=no \
git://github.com/rails/rails.git "refs/*:refs/*"
[this still isn't done after 10 _minutes_ of pegging the CPU]
git fetch \
git://github.com/rails/rails.git "refs/*:refs/*"
You can produce a quicker and simpler test case like this:
doit() {
head=`git rev-parse HEAD`
for i in `seq 1 $1`; do
echo $head refs/heads/ref$i
done >.git/packed-refs
echo "==> $1"
rm -rf dest
git init -q --bare dest &&
(cd dest && time git.compile fetch -q .. refs/*:refs/*)
}
rm -rf repo
git init -q repo && cd repo &&
>file && git add file && git commit -q -m one
doit 100
doit 200
doit 400
doit 800
doit 1600
doit 3200
Which yields timings like:
# refs seconds of CPU
100 0.06
200 0.24
400 0.95
800 3.39
1600 13.66
3200 54.09
Notice that although the number of refs doubles in each
trial, the CPU time spent quadruples.
The problem is that the submodule recursion code works
something like:
- for each ref we fetch
- for each commit in git rev-list $new_sha1 --not --all
- add modified submodules to list
- fetch any newly referenced submodules
But that means if we fetch N refs, we start N revision
walks. Worse, because we use "--all", the number of refs we
must process that constitute "--all" keeps growing, too. And
you end up doing O(N^2) ref resolutions.
Instead, this patch structures the code like this:
- for each sha1 we already have
- add $old_sha1 to list $old
- for each ref we fetch
- add $new_sha1 to list $new
- for each commit in git rev-list $new --not $old
- add modified submodules to list
- fetch any newly referenced submodules
This yields timings like:
# refs seconds of CPU
100 0.00
200 0.04
400 0.04
800 0.10
1600 0.21
3200 0.39
Note that the amount of effort doubles as the number of refs
doubles. Similarly, the fetch of rails.git takes about as
much time as it does with --recurse-submodules=no.

The "git fetch" command works in two phases. The remote side tells us what
objects are at the tip of the refs we are fetching from, and transfers the
objects missing from our side. After storing the objects in our repository,
we update our remote tracking branches to point at the updated tips of the
refs.
A broken or malicious remote side could send a perfectly well-formed pack
data during the object transfer phase, but there is no guarantee that the
given data actually fill the gap between the objects we originally had and
the refs we are updating to.
Although this kind of breakage can be caught by running fsck after a
fetch, it is much cheaper to verify that everything that is reachable from
the tips of the refs we fetched are indeed fully connected to the tips of
our current set of refs before we update them.

Generally the format of a git tag or commit message is:
subject
body body body
body body body
However, we occasionally see multiline subjects like:
subject
with multiple
lines
body body body
body body body
The rest of git treats these multiline subjects as something
to be concatenated and shown as a single line (e.g., "git
log --pretty=format:%s" will do so since f53bd74). For
consistency, for-each-ref should do the same with its

The find_subpos function was a little hard to use, as well
as to read. It would sometimes write into the subject and
body pointers, and sometimes not. The body pointer sometimes
could be compared to subject, and sometimes not. When
actually duplicating the subject, the caller was forced to
figure out again how long the subject is (which is not too
big a deal when the subject is a single line, but hard to
extend).
The refactoring makes the function more straightforward, both
to read and to use. We will always put something into the
subject and body pointers, and we return explicit lengths
for them, too.
This lays the groundwork both for more complex subject
parsing (e.g., multiline), as well as splitting the body
into subparts (like the text versus the signature).

Implement a gate between git and mediawiki, allowing git users to push
and pull objects from mediawiki just as one would do with a classic git
repository thanks to remote-helpers.
The following packages need to be installed (available on common
repositories):
libmediawiki-api-perl
libdatetime-format-iso8601-perl
Use remote helpers in order to be as transparent as possible to the git
user.
Download Mediawiki revisions through the Mediawiki API and then
fast-import into git.
Mediawiki revision number and git commits are linked thanks to notes
bound to commits.
The import part is done on a refs/mediawiki/<remote> branch before
coming to refs/remote/origin/master (Huge thanks to Jonathan Nieder
for his help)
We use UTF-8 everywhere: use encoding 'utf8'; does most of the job, but
we also read the output of Git commands in UTF-8 with the small helper
run_git, and write to the console (STDERR) in UTF-8. This allows a
seamless use of non-ascii characters in page titles, but hasn't been
tested on non-UTF-8 systems. In particular, UTF-8 encoding for filenames
could raise problems if different file systems handle UTF-8 filenames
differently. A uri_escape of mediawiki filenames could be imaginable, and
is still to be discussed further.
Partial cloning is supported using one of:
git clone -c remote.origin.pages='A_Page Another_Page' mediawiki::http://wikiurl
git clone -c remote.origin.categories='Some_Category' mediawiki::http://wikiurl
git clone -c remote.origin.shallow='True' mediawiki::http://wikiurl
Thanks to notes metadata, it is possible to compare remote and local last
mediawiki revision to warn non-fast forward pushes and "everything
up-to-date" case.
When allowed, push looks for each commit between remotes/origin/master
and HEAD, catches every blob related to these commit and push them in
chronological order. To do so, it uses git rev-list --children HEAD and
travels the tree from remotes/origin/master to HEAD through children. In
other words:
* Shortest path from remotes/origin/master to HEAD
* For each commit encountered, push blobs related to this commit

The current remote helper documentation is from the perspective of
git, so to speak: it presents a full menu of commands for a person
invoking a remote helper to choose from. In practice, that's less
useful than it could be, since the daunted novice remote-helper author
probably just wanted a list of commands needs to implement to get
started. So preface the command list with an overview of each
capability, its purpose, and what commands it requires.
As a side effect, this makes it a little clearer that git doesn't
choose arbitrary commands to run, even if the remote helper advertises
all capabilities --- instead, there are well defined command sequences
for various tasks.

In the case where sb is initialized to the slopbuf (through
strbuf_init(sb,0) or STRBUF_INIT), strbuf_grow() loses the terminating
nul: it grows the buffer, but gives ALLOC_GROW a NULL source to avoid
it being freed. So ALLOC_GROW does not copy anything to the new
memory area.
This subtly broke the call to strbuf_getline in read_next_command()
[fast-import.c:1855], which goes
strbuf_detach(&command_buf, NULL); # command_buf is now = STRBUF_INIT
stdin_eof = strbuf_getline(&command_buf, stdin, '\n');
if (stdin_eof)
return EOF;
In strbuf_getwholeline, this did
strbuf_grow(sb, 0); # loses nul-termination
if (feof(fp))
return EOF;
strbuf_reset(sb); # this would have nul-terminated!
Valgrind found this because fast-import subsequently uses prefixcmp()
on command_buf.buf, which after the EOF exit contains only
uninitialized memory.
Arguably strbuf_getwholeline is also broken, in that it touches the
buffer before deciding whether to do any work. However, it seems more
futureproof to not let the strbuf API lose the nul-termination by its
own fault.
So make sure that strbuf_grow() puts in a nul even if it has nowhere
to copy it from. This makes strbuf_grow(sb, 0) a semantic no-op as
far as readers of the buffer are concerned.
Also remove the nul-termination added by strbuf_init, which is made
redudant.

The current explanation of -e can be misread as allowing the user to say
I know 'git clean -XYZ' (substitute -XYZ with any option and/or

except for paths matching this pattern by adding '-e C' to the same
command line, i.e. 'git clean -e C -XYZ'.
But that is not what this option does. It augments the set of ignore rules
from the command line, just like the same "-e <pattern>" argument does
with the "ls-files" command (the user could probably pass "-e \!C" to tell
the command to clean everything the command would normally remove, except
for C). Also error out when both -x and -e are given with an explanation of
what -e means---it is a symptom of misunderstanding what -e does.

Given a complex set of revision specifiers on the command line, it is too
late to look at the flags of the objects in the initial traversal list at
the beginning of limit_list() in order to determine what the objects the
end-user explicitly listed on the command line were. The process to move
objects from the pending array to the traversal list may have marked
objects that are not mentioned as UNINTERESTING, when handle_commit()
marked the parents of UNINTERESTING commits mentioned on the command line
by calling mark_parents_uninteresting().
This made "rev-list --ancestry-path ^A ..." to mistakenly list commits
that are descendants of A's parents but that are not descendants of A
itself, as ^A from the command line causes A and its parents marked as
UNINTERESTING before coming to limit_list(), and we try to enumerate the
commits that are descendants of these commits that are UNINTERESTING
before we start walking the history.
It actually is too late even if we inspected the pending object array
before calling prepare_revision_walk(), as some of the same objects might
have been mentioned twice, once as positive and another time as negative.
The "rev-list --some-option A --not --all" command may want to notice,
even if the resulting set is empty, that the user showed some interest in
"A" and do something special about it.
Prepare a separate array to keep track of what syntactic element was used
to cause each object to appear in the pending array from the command line,
and populate it as setup_revisions() parses the command line.

Cloning from a local repository blindly copies or hardlinks all the files
under objects/ hierarchy. This results in two issues:
- If the repository cloned has an "objects/info/alternates" file, and the
command line of clone specifies --reference, the ones specified on the
command line get overwritten by the copy from the original repository.
- An entry in a "objects/info/alternates" file can specify the object
stores it borrows objects from as a path relative to the "objects/"
directory. When cloning a repository with such an alternates file, if
the new repository is not sitting next to the original repository, such
relative paths needs to be adjusted so that they can be used in the new
repository.

All branches in the Perforce server are downloaded to allow branch detection. If
you have a centralized server on a remote location and there is a big number of
branches this operation can take some time.
This patch adds the configuration option git-p4.branchUser to allow filtering
the branch list by user. Although this limits the branch maintenance in Perforce
to be done by a single user, it might be an advantage when the number of
branches being used in a specific depot is very small when compared with the

When branch detection is enabled each branch is named in git after their
relative depot path in Perforce. To do this the depot paths are compared against
each other to find their common base path. The current algorithm makes this
comparison on a character by character basis.
Assuming we have the following branches:
//depot/branches/featureA
//depot/branches/featureB
Then the base depot path would be //depot/branches/feature, which is an invalid
depot path.
The current patch fixes this by splitting the path into a list and comparing the
list entries, making it choose correctly //depot/branches as the base path.

directories without loosing the information from their .git directory
as that is now stored outside the submodules work tree.
This is done relying on the already existent .git-file functionality.

"git branch -M <foo> <current-branch>" allows updating the current branch
which HEAD points, without the necessary house-keeping that git reset
normally does to make this operation sensible. It also leaves the reflog
in a confusing state (you would be warned when trying to read it).
"git checkout -B <current branch> <foo>" is also partly vulnerable to this
bug; due to inconsistent pre-flight checks it would perform half of its
task and then abort just before rewriting the branch. Again this
manifested itself as the index file getting out-of-sync with HEAD.
"git branch -f" already guarded against this problem, and aborts with
a fatal error.
Update "git branch -M", "git checkout -B" and "git branch -f" to share the
same check before allowing a branch to be created. These prevent you from
updating the current branch.
We considered suggesting the use of "git reset" in the failure message

Delta base for blobs is chosen as a previously saved blob. If we
treat cat-blob's blob as a delta base for the next blob, nothing
is likely to become worse.
For fast-import stream producer like svn-fe cat-blob is used like
following:
- svn-fe reads file delta in svn format
- to apply it, svn-fe asks cat-blob 'svn delta base'
- applies 'svn delta' to the response
- produces a blob command to store the result
Currently there is no way for svn-fe to give fast-import a hint on
object delta base. While what's requested in cat-blob is most of
the time a best delta base possible. Of course, it could be not a
good delta base, but we don't know any better one anyway.
So do treat cat-blob's result as a delta base for next blob. The
profit is nice: 2x to 7x reduction in pack size AND 1.2x to 3x
time speedup due to diff_delta being faster on good deltas. git gc
--aggressive can compress it even more, by 10% to 70%, utilizing
more cpu time, real time and 3 cpu cores.
Tested on 213M and 2.7G fast-import streams, resulting packs are 22M
and 113M, import time is 7s and 60s, both streams are produced by
svn-fe, sniffed and then used as raw input for fast-import.
For git-fast-export produced streams there is no change as it doesn't
use cat-blob and doesn't try to reorder blobs in some smart way to
make successive deltas small.

It's an interesting number, how often do we try to deltify each type of
objects and how often do we succeed. So do add it to stats.
Success doesn't mean much gain in pack size though. As we allow delta to
be as big as (data.len - 20). And delta close to data.len gains nothing
compared to no delta at all even after zlib compression (delta is pretty
much the same as data, just with few modifications).
We should try to make less attempts that result in huge deltas as these
consume more cpu than trivial small deltas. Either by choosing a better
delta base or reducing delta size upper bound or doing less delta attempts
at all.
Currently, delta base for blobs is a waste literally. Each blob delta
base is chosen as a previously stored blob. Disabling deltas for blobs
doesn't increase pack size and reduce import time, or at least doesn't
increase time for all fast-import streams I've tried.

This teaches combine-diff machinery to feed a combined merge to a callback
function when DIFF_FORMAT_CALLBACK is specified.
So far, format callback functions are not used for anything but 2-way
diffs. A callback is given a diff_queue_struct, which is an array of
diff_filepair. As its name suggests, a diff_filepair is a _pair_ of
diff_filespec that represents a single preimage and a single postimage.
Since "diff -c" is to compare N parents with a single merge result and
filter out any paths whose result match one (or more) of the parent(s),
its output has to be able to represent N preimages and 1 postimage. For
this reason, a callback function that inspects a diff_filepair that
results from this new infrastructure can and is expected to view the
preimage side (i.e. pair->one) as an array of diff_filespec. Each element
in the array, except for the last one, is marked with "has_more_entries"
bit, so that the same callback function can be used for 2-way diffs and
combined diffs.

All of the "do we want color" flags default to -1 to
indicate that we don't have any color configured. This value
is handled in one of two ways:
1. In porcelain, we check early on whether the value is
still -1 after reading the config, and set it to the
value of color.ui (which defaults to 0).
2. In plumbing, it stays untouched as -1, and want_color
defaults it to off.
This works fine, but means that every porcelain has to check
and reassign its color flag. Now that want_color gives us a
place to put this check in a single spot, we can do that,
simplifying the calling code.

The diff config callback is split into two functions: one
which loads "ui" config, and one which loads "basic" config.
The former chains to the latter, as the diff UI config is a
superset of the plumbing config.
The color.diff variable is only loaded in the UI config.
However, the basic config actually chains to
git_color_default_config, which loads color.ui. This doesn't
actually cause any bugs, because the plumbing diff code does
not actually look at the value of color.ui.
However, it is somewhat nonsensical, and it makes it
difficult to refactor the color code. It probably came about
because there is no git_color_config to load only color
config, but rather just git_color_default_config, which
loads color config and chains to git_default_config.
This patch splits out the color-specific portion of
git_color_default_config so that the diff UI config can call
it directly. This is perhaps better explained by the
chaining of callbacks. Before we had:
git_diff_ui_config
-> git_diff_basic_config
-> git_color_default_config
-> git_default_config
Now we have:
git_diff_ui_config
-> git_color_config
-> git_diff_basic_config
-> git_default_config

For "git config --get-colorbool color.foo", we use a custom
callback that looks not only for the key that the user gave
us, but also for "diff.color" (for backwards compatibility)
and "color.ui" (as a fallback).
For the former, we use a custom variable to store the
diff.color value. For the latter, though, we store it in the
main "git_use_color_default" variable, turning on color.ui
for any other parts of git that respect this value.
In practice, this doesn't cause any bugs, because git-config
runs without caring about git_use_color_default, and then
exits. But it crosses module boundaries in an unusual and
confusing way, and it makes refactoring color handling
harder than it needs to be.

When we read a color value either from a config file or from
the command line, we use git_config_colorbool to convert it
from the tristate always/never/auto into a single yes/no
boolean value.
This has some timing implications with respect to starting
a pager.
If we start (or decide not to start) the pager before
checking the colorbool, everything is fine. Either isatty(1)
will give us the right information, or we will properly
check for pager_in_use().
However, if we decide to start a pager after we have checked
the colorbool, things are not so simple. If stdout is a tty,
then we will have already decided to use color. However, the
user may also have configured color.pager not to use color
with the pager. In this case, we need to actually turn off
color. Unfortunately, the pager code has no idea which color
variables were turned on (and there are many of them
throughout the code, and they may even have been manipulated
after the colorbool selection by something like "--color" on
the command line).
This bug can be seen any time a pager is started after
config and command line options are checked. This has
affected "git diff" since 89d07f7 (diff: don't run pager if
user asked for a diff style exit code, 2007-08-12). It has
also affect the log family since 1fda91b (Fix 'git log'
early pager startup error case, 2010-08-24).
This patch splits the notion of parsing a colorbool and
actually checking the configuration. The "use_color"
variables now have an additional possible value,
GIT_COLOR_AUTO. Users of the variable should use the new
"want_color()" wrapper, which will lazily determine and
cache the auto-color decision.

calls to DIFF_OPT_TST must check for "o->use_color > 0",

We have always set a global "spawned_pager" variable when we
start the pager. This lets us make the auto-color decision
later in the program as as "we are outputting to a terminal,
or to a pager which can handle colors".
Commit 6e9af86 added support for the GIT_PAGER_IN_USE
environment variable. An external program calling git (e.g.,
git-svn) could set this variable to indicate that it had
already started the pager, and that the decision about
auto-coloring should take that into account.
However, 6e9af86 failed to do the reverse, which is to tell
external programs when git itself has started the pager.
Thus a git command implemented as an external script that
has the pager turned on (e.g., "git -p stash show") would
not realize it was going to a pager, and would suppress
colors.
This patch remedies that; we always set GIT_PAGER_IN_USE
when we start the pager, and the value is respected by both
this program and any spawned children.

There are a few common tasks when working with configuration
variables in tests; this patch aims to make them a little
easier to write and less error-prone.
When setting a variable, you should typically make sure to
clean it up after the test is finished, so as not to pollute
other tests. Like:
test_when_finished 'git config --unset foo.bar' &&
git config foo.bar baz
This patch lets you just write:
test_config foo.bar baz
When clearing a variable that does not exist, git-config
will report a specific non-zero error code. Meaning that
tests which call "git config --unset" often either rely on
the prior tests having actually set it, or must use
test_might_fail. With this patch, the previous:
test_might_fail git config --unset foo.bar
becomes:
test_unconfig foo.bar
Not only is this easier to type, but it is more robust; it
will correctly detect errors from git-config besides "key
was not set".

--import-marks option can be set via a "feature" command in a fast-import
stream and --import-marks-if-exists had support for such specification
from the very beginning too due to some shared codebase. Though the
documentation for this feature wasn't written in dded4f1.
Add the documentation for "feature import-marks-if-exists=<file>". Also add
a minimalistic test for it.

To produce deltas for tree objects fast-import tracks two versions
of tree's entries - base and current one. Base version stands both
for a delta base of this tree, and for a entry inside a delta base
of a parent tree. So care should be taken to keep it in sync.
tree_content_set cuts away a whole subtree and replaces it with a
new one (or NULL for lazy load of a tree with known sha1). It
keeps a base sha1 for this subtree (needed for parent tree). And
here is the problem, 'subtree' tree root doesn't have the implied
base version entries.
Adjusting the subtree to include them would mean a deep rewrite of
subtree. Invalidating the subtree base version would mean recursive
invalidation of parents' base versions. So just mark this tree as
do-not-delta me. Abuse setuid bit for this purpose.
tree_content_replace is the same as tree_content_set except that is
is used to replace the root, so just clearing base sha1 here (instead
of setting the bit) is fine.

In this test, we have merge two branches. On one branch, we
renamed "a" to "e". On the other, we renamed "a" to "e" and
then added a symlink pointing at "a" pointing to "e".
The results for the test indicate that the merge should
succeed, but also that "a" should no longer exist. Since
both sides renamed "a" to the same destination, we will end
up comparing those destinations for content.
But what about what's left? One side (the rename only),
replaced "a" with nothing. The other side replaced it with a
symlink. The common base must also be nothing, because any
"a" before this was meaningless (it was totally unrelated
content that ended up getting renamed).
The only sensible resolution is to keep the symlink. The
rename-only side didn't touch the content versus the common
base, and the other side added content. The 3-way merge
dictates that we take the side with a change.
And this gives the overall merge an intuitive result. One
side made one change (a rename), and the other side made two
changes: an identical rename, and an addition (that just
happened to be at the same spot). The end result should
contain both changes.

Our previous conflict resolution for renaming two different files to the
same name ignored the fact that each of those files may have modifications
from both sides of history to consider. We need to do a three-way merge
for each of those files, and then handle the conflict of both sets of
merged contents trying to be recorded with the same name.
It is important to note that this changes our strategy in the recursive
case. After doing a three-way content merge of each of the files
involved, we still are faced with the fact that we are trying to put both
of the results (including conflict markers) into the same path. We could
do another two-way merge, but I think that becomes confusing. Also,
taking a hint from the modify/delete and rename/delete cases we handled
earlier, a more useful "common ground" would be to keep the three-way
content merge but record it with the original filename. The renames can
still be detected, we just allow it to be done in the o->call_depth=0
case. This seems to result in simpler & easier to understand merge
conflicts as well, as evidenced by some of the changes needed in our
testsuite in t6036. (However, it should be noted that this change will
cause problems those renames also occur along with a file being added
whose name matches the source of the rename. Since git currently cannot
detect rename/add-source situations, though, this codepath is not
currently used for those cases anyway.

When o->call_depth>0 and we have conflicts, we try to find "middle ground"
when creating the virtual merge base. In the case of content conflicts,
this can be done by doing a three-way content merge and using the result.
In all parts where the three-way content merge is clean, it is the correct
middle ground, and in parts where it conflicts there is no middle ground
but the conflict markers provide a good compromise since they are unlikely
to accidentally match any further changes.
In the case of a modify/delete conflict, we cannot do the same thing.
Accepting either endpoint as the resolution for the virtual merge base
runs the risk that when handling the non-recursive case we will silently
accept one person's resolution over another without flagging a conflict.
In this case, the closest "middle ground" we have is actually the merge
base of the candidate merge bases. (We could alternatively attempt a
three way content merge using an empty file in place of the deleted file,
but that seems to be more work than necessary.)

In 882fd11 (merge-recursive: Delay content merging for renames 2010-09-20),
there was code that checked for whether we could skip updating a file in
the working directory, based on whether the merged version matched the
current working copy. Due to the desire to handle directory/file conflicts
that were resolvable, that commit deferred content merging by first
updating the index with the unmerged entries and then moving the actual
merging (along with the skip-the-content-update check) to another function
that ran later in the merge process. As part moving the content merging
code, a bug was introduced such that although the message about skipping
the update would be printed (whenever GIT_MERGE_VERBOSITY was sufficiently
high), the file would be unconditionally updated in the working copy
anyway.
When we detect that the file does not need to be updated in the working
copy, update the index appropriately and then return early before updating
the working copy.
Note that there was a similar change in b2c8c0a (merge-recursive: When we
detect we can skip an update, actually skip it 2011-02-28), but it was
reverted by 6db4105 (Revert "Merge branch 'en/merge-recursive'"
2011-05-19) since it did not fix both of the relevant types of unnecessary
update breakages and, worse, it made use of some band-aids that caused
other problems. The reason this change works is due to the changes earlier
in this series to (a) record_df_conflict_files instead of just unlinking
them early, (b) allowing make_room_for_path() to remove D/F entries,
(c) the splitting of update_stages_and_entry() to have its functionality
called at different points, and (d) making the pathnames of the files
involved in the merge available to merge_content().

In the recursive case (o->call_depth > 0), we do not modify the working
directory. However, when o->call_depth==0, file renames can mean we need
to delete the old filename from the working copy. Since there have been
lots of changes and mistakes here, let's go through the details. Let's
start with a simple explanation of what we are trying to achieve:
Original goal: If a file is renamed on the side of history being merged
into head, the filename serving as the source of that rename needs to be
removed from the working directory.
The path to getting the above statement implemented in merge-recursive took
several steps. The relevant bits of code may be instructive to keep in
mind for the explanation, especially since an English-only description
involves double negatives that are hard to follow. These bits of code are:
int remove_file(..., const char *path, int no_wd)
{
...
int update_working_directory = !o->call_depth && !no_wd;
and
remove_file(o, 1, ren1_src, <expression>);
Where the choice for <expression> has morphed over time:
65ac6e9 (merge-recursive: adjust to loosened "working file clobbered"
check 2006-10-27), introduced the "no_wd" parameter to remove_file() and
used "1" for <expression>. This meant ren1_src was never deleted, leaving
it around in the working copy.
In 8371234 (Remove uncontested renamed files during merge. 2006-12-13),
<expression> was changed to "index_only" (where index_only ==
!!o->call_depth; see b7fa51da). This was equivalent to using "0" for
<expression> (due to the early logic in remove_file), and is orthogonal to
the condition we actually want to check at this point; it resulted in the
source file being removed except when index_only was false. This was
problematic because the file could have been renamed on the side of history
including head, in which case ren1_src could correspond to an untracked
file that should not be deleted.
In 183d797 (Keep untracked files not involved in a merge. 2007-02-04),
<expression> was changed to "index_only || stage == 3". While this gives
correct behavior, the "index_only ||" portion of <expression> is
unnecessary and makes the code slightly harder to follow.
There were also two further changes to this expression, though without
any change in behavior. First in b7fa51d (merge-recursive: get rid of the
index_only global variable 2008-09-02), it was changed to "o->call_depth
|| stage == 3". (index_only == !!o->call_depth). Later, in 41d70bd6
(merge-recursive: Small code clarification -- variable name and comments),
this was changed to "o->call_depth || renamed_stage == 2" (where stage was
renamed to other_stage and renamed_stage == other_stage ^ 1).
So we ended with <expression> being "o->call_depth || renamed_stage == 2".
But the "o->call_depth ||" piece was unnecessary. We can remove it,
leaving us with <expression> being "renamed_stage == 2". This doesn't
change behavior at all, but it makes the code clearer. Which is good,
because it's about to get uglier.
Corrected goal: If a file is renamed on the side of history being merged
into head, the filename serving as the source of that rename needs to be
removed from the working directory *IF* that file is tracked in head AND
the file tracked in head is related to the original file.
Note that the only difference between the original goal and the corrected
goal is the two extra conditions added at the end. The first condition is
relevant in a rename/delete conflict. If the file was deleted on the
HEAD side of the merge and an untracked file of the same name was added to
the working copy, then without that extra condition the untracked file
will be erroneously deleted. This changes <expression> to "renamed_stage
== 2 || !was_tracked(ren1_src)".
The second additional condition is relevant in two cases.
The first case the second condition can occur is when a file is deleted
and a completely different file is added with the same name. To my
knowledge, merge-recursive has no mechanism for detecting deleted-and-
replaced-by-different-file cases, so I am simply punting on this
possibility.
The second case for the second condition to occur is when there is a
rename/rename/add-source conflict. That is, when the original file was
renamed on both sides of history AND the original filename is being
re-used by some unrelated (but tracked) content. This case also presents
some additional difficulties for us since we cannot currently detect these
rename/rename/add-source conflicts; as long as the rename detection logic
"optimizes" by ignoring filenames that are present at both ends of the
diff, these conflicts will go unnoticed. However, rename/rename conflicts
are handled by an entirely separate codepath not being discussed here, so
this case is not relevant for the line of code under consideration.
In summary:
Change <expression> from "o->call_depth || renamed_stage == 2" to
"renamed_stage == 2 || !was_tracked(ren1_src)", in order to remove
unnecessary code and avoid deleting untracked files.

Previously, we were using lstat() to determine if a directory was still
present after a merge (and thus in the way of adding a file). We should
have been using lstat() only to determine if untracked directories were in
the way (and then only when necessary to check for untracked directories);
we should instead using the index to determine if there is a tracked
directory in the way. Create a new function to do this and use it to

make_room_for_directories_of_df_conflicts() is about making sure necessary
working directory changes can succeed. When o->call_depth > 0 (i.e. the
recursive case), we do not want to make any working directory changes so
this function should be skipped.
Note that make_room_for_directories_of_df_conflicts() is broken as has
been pointed out by Junio; it should NOT be unlinking files. What it
should do is keep track of files that could be unlinked if a directory
later needs to be written in their place. However, that work also is only
relevant in the non-recursive case, so this change is helpful either way.

Add testcases that cover three failures with current git merge, all
involving renaming one file on both sides of history:
Case 1:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. Adding a new file on one of those
sides of history whose name happens to match the rename source should not
cause the merge to suddenly succeed.
Case 2:
If a single file is renamed on both sides of history but renamed
identically, there should not be a conflict. This works fine. However,
if one of those sides also added a new file that happened to match the
rename source, then that file should be left alone. Currently, the
rename/rename conflict handling causes that new file to become untracked.
Case 3:
If a single file is renamed to two different filenames on different sides
of history, there should be a conflict. This works currently. However,
if those renames also involve rename/add conflicts (i.e. there are new
files on one side of history that match the destination of the rename of
the other side of history), then the resulting conflict should be recorded
in the index, showing that there were multiple files with a given filename.
Currently, git silently discards one of file versions.

Add testcases that cover a variety of merge issues with files being
renamed and modified on different sides of history, when there are
directories possibly conflicting with the rename location.
Case 1:
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a non-conflicting
way but is renamed to the location of the new directory.
Case 2:
[Same as case 1, but there is also a content conflict. In detail:]
On one side of history, a file is modified and a new directory is added.
On the other side of history, the file is modified in a conflicting way
and it is renamed to the location of the new directory.
Case 3:
[Similar to case 1, but the "conflicting" directory is the directory
where the file original resided. In detail:]
On one side of history, a file is modified. On the other side of history,
the file is modified in a non-conflicting way, but the directory it was
under is removed and the file is renamed to the location of the directory
it used to reside in (i.e. 'sub/file' gets renamed to 'sub'). This is
flagged as a directory/rename conflict, but should be able to be resolved
since the directory can be cleanly removed by the merge.
One branch renames a file and makes a file where the directory the renamed
file used to be in, and the other branch updates the file in
place. Merging them should resolve it cleanly as long as the content level
change on the branches do not overlap and rename is detected, or should
leave conflict without losing information.

The following sequence of commands reveals an issue with error
reporting of relative paths:
$ mkdir sub

$ git ls-files --error-unmatch ../bbbbb
error: pathspec 'b' did not match any file(s) known to git.
$ git commit --error-unmatch ../bbbbb
error: pathspec 'b' did not match any file(s) known to git.
This bug is visible only if the normalized path (i.e., the relative
path from the repository root) is longer than the prefix.
Otherwise, the code skips over the normalized path and reads from
an unused memory location which still contains a leftover of the
original command line argument.
So instead, use the existing facilities to deal with relative paths
correctly.
Also fix inconsistency between "checkout" and "commit", e.g.
$ cd Documentation
$ git checkout nosuch.txt

Git currently reports loose objects as 'corrupt' if they've been
deflated using a window size less than 32Kb, because the
experimental_loose_object() function doesn't recognise the header
byte as a zlib header. This patch makes the function tolerant of
all valid window sizes (15-bit to 8-bit) - but doesn't sacrifice
it's accuracy in distingushing the standard loose-object format
from the experimental (now abandoned) format.
On memory constrained systems zlib may use a much smaller window
size - working on Agit, I found that Android uses a 4KB window;
giving a header byte of 0x48, not 0x78. Consequently all loose
objects generated appear 'corrupt', which is why Agit is a read-only
Git client at this time - I don't want my client to generate Git
repos that other clients treat as broken :(
This patch makes Git tolerant of different deflate settings - it
might appear that it changes experimental_loose_object() to the point
where it could incorrectly identify the experimental format as the
standard one, but the two criteria (bitmask & checksum) can only
give a false result for an experimental object where both of the
following are true:
1) object size is exactly 8 bytes when uncompressed (bitmask)
2) [single-byte in-pack git type&size header] * 256
+ [1st byte of the following zlib header] % 31 = 0 (checksum)
As it happens, for all possible combinations of valid object type
(1-4) and window bits (0-7), the only time when the checksum will be
divisible by 31 is for 0x1838 - ie object type *1*, a Commit - which,
due the fields all Commit objects must contain, could never be as
small as 8 bytes in size.
Given this, the combination of the two criteria (bitmask & checksum)
always correctly determines the buffer format, and is more tolerant
than the previous version.
The alternative to this patch is simply removing support for the
experimental format, which I am also totally cool with.

The documentation declares following identity format:

where name is any string without LF and LT characters.
But fast-import just accepts any string up to first GT
instead of checking the whole format, and moreover just
writes it as is to the commit object.
git-fsck checks for [^<\n]* <[^<>\n]*> format. Note that the

extending the string to the left when needed.
Modify fast-import input identity format to a slightly stricter

fast-import format declares 'committer_name SP' to be optional in
'committer_name SP LT email GT'. But for a (commit) object SP is
obligatory while zero length committer_name is ok. git-fsck checks
that SP is present, so fast-import must prepend it if the name SP
part is omitted. It doesn't do so and thus for "LT email GT" ident
it writes a bad object.
Name cannot contain LT or GT, ident always comes after SP in fast-import.
So if ident starts with LT reuse the SP as if a valid 'SP LT email GT'
ident was passed.
This fixes a ident parsing bug for a well-formed fast-import input.

A request to fetch from a client over smart HTTP protocol is served in
multiple steps. In the first round, the server side shows the set of refs
it has and their values, and the client picks from them and sends "I want
to fetch the history leading to these commits".
When the server tries to respond to this second request, its refs may have
progressed by a push from elsewhere. By design, we do not allow fetching
objects that are not at the tip of an advertised ref, and the server
rejects such a request. The client needs to try again, which is not ideal
especially for a busy server.

In olden times, tests would quietly exit the script when they failed
at an inconvenient moment, which was a little disconcerting.
Therefore v0.99.5~24^2~4 (Trapping exit in tests, using return for
errors, 2005-08-10) switched to an idiom of using "return" instead,
wrapping evaluation of test code in a function to make that safe:
test_run_ () {
eval >&3 2>&4 "$1"
eval_ret="$?"
return 0
}
Years later, the implementation of test_when_finished (v1.7.1.1~95,
2010-05-02) and v1.7.2-rc2~1^2~13 (test-lib: output a newline before
"ok" under a TAP harness, 2010-06-24) took advantage of test_run_ as a
place to put code shared by all test assertion functions, without
paying attention to the function's former purpose:
test_run_ () {
...
eval >&3 2>&4 "$1"
eval_ret=$?
if should run cleanup
then
eval >&3 2>&4 "$test_cleanup"
fi
if TAP format requires a newline here
then
echo
fi
return 0
}
That means cleanup commands and the newline to put TAP output at
column 0 are skipped when tests use "return" to fail early. Fix it by
introducing a test_eval_ function to catch the "return", with a
comment explaining the new function's purpose for the next person who
might touch this code.

tests that fail early could be distinguished from tests that completed
normally with successful (nonzero) status. Eventually tests that
succeed with nonzero status were phased out (see v1.7.4-rc0~65^2~19,

Currently, revert_or_cherry_pick can fail in two ways. If it
encounters a conflict, it returns a positive number indicating the
intended exit status for the git wrapper to pass on; for all other
errors, it calls die(). The latter behavior is inconsiderate towards
callers, as it denies them the opportunity to recover from errors and
do other things.
After this patch, revert_or_cherry_pick will still return a positive
return value to indicate an exit status for conflicts as before, while
for some other errors, it will print an error message and return -1
instead of die()-ing. The cmd_revert and cmd_cherry_pick are adjusted
to handle the fatal errors by die()-ing themselves.
While the full benefits of this patch will only be seen once all the
"die" calls are replaced with calls to "error", its immediate impact
is to change some "fatal:" messages to say "error:" and to add a new
"fatal: cherry-pick failed" message at the end when the operation
fails.

Introduce a new "git cherry-pick --continue" command which uses the
information in ".git/sequencer" to continue a cherry-pick that stopped
because of a conflict or other error. It works by dropping the first
instruction from .git/sequencer/todo and performing the remaining
cherry-picks listed there, with options (think "-s" and "-X") from the
initial command listed in ".git/sequencer/opts".
So now you can do:
$ git cherry-pick -Xpatience foo..bar
... description conflict in commit moo ...
$ git cherry-pick --continue
error: 'cherry-pick' is not possible because you have unmerged files.
fatal: failed to resume cherry-pick
$ echo resolved >conflictingfile
$ git add conflictingfile && git commit
$ git cherry-pick --continue; # resumes with the commit after "moo"
During the "git commit" stage, CHERRY_PICK_HEAD will aid by providing
the commit message from the conflicting "moo" commit. Note that the
cherry-pick mechanism has no control at this stage, so the user is
free to violate anything that was specified during the first
cherry-pick invocation. For example, if "-x" was specified during the
first cherry-pick invocation, the user is free to edit out the message
during commit time. Note that the "--signoff" option specified at
cherry-pick invocation time is not reflected in the commit message
provided by CHERRY_PICK_HEAD; the user must take care to add
"--signoff" during the "git commit" invocation.

Protect the user from forgetting about a pending sequencer operation
by immediately erroring out when an existing cherry-pick or revert
operation is in progress like:
$ git cherry-pick foo
... conflict ...
$ git cherry-pick moo
error: .git/sequencer already exists
hint: A cherry-pick or revert is in progress
hint: Use --reset to forget about it
fatal: cherry-pick failed
A naive version of this would break the following established ways of
working:
$ git cherry-pick foo
... conflict ...
$ git reset --hard # I actually meant "moo" when I said "foo"
$ git cherry-pick moo
$ git cherry-pick foo
... conflict ...
$ git commit # commit the resolution
$ git cherry-pick moo # New operation
However, the previous patches "reset: Make reset remove the sequencer
state" and "revert: Remove sequencer state when no commits are
pending" make sure that this does not happen.

When cherry-pick or revert is called on a list of commits, and a
conflict encountered somewhere in the middle, the data in
".git/sequencer" is required to continue the operation. However, when
a conflict is encountered in the very last commit, the user will have
to "continue" after resolving the conflict and committing just so that
the sequencer state is removed. This is how the current "rebase -i"
script works as well.
$ git cherry-pick foo..bar
... conflict encountered while picking "bar" ...
$ echo "resolved" >problematicfile
$ git add problematicfile
$ git commit
$ git cherry-pick --continue # This would be a no-op
Change this so that the sequencer state is cleared when a conflict is
encountered in the last commit. Incidentally, this patch makes sure
that some existing tests don't break when features like "--reset" and
"--continue" are implemented later in the series.
A better way to implement this feature is to get the last "git commit"
to remove the sequencer state. However, that requires tighter
coupling between "git commit" and the sequencer, a goal that can be
pursued once the sequencer is made more general.

Years of muscle memory have trained users to use "git reset --hard" to
remove the branch state after any sort operation. Make it also remove
the sequencer state to facilitate this established workflow:
$ git cherry-pick foo..bar
... conflict encountered ...
$ git reset --hard # Oops, I didn't mean that
$ git cherry-pick quux..bar
... cherry-pick succeeded ...
Guard against accidental removal of the sequencer state by providing
one level of "undo". In the first "reset" invocation,
".git/sequencer" is moved to ".git/sequencer-old"; it is completely
removed only in the second invocation.

Many pathnames in a fast-import stream need to be quoted. In
particular:
1. Pathnames at the end of an "M" or "D" line need quoting
if they contain a LF or start with double-quote.
2. Pathnames on a "C" or "R" line need quoting as above,
but also if they contain spaces.
For (1), we weren't quoting at all. For (2), we put
double-quotes around the paths to handle spaces, but ignored
the possibility that they would need further quoting.
This patch checks whether each pathname needs c-style
quoting, and uses it. This is slightly overkill for (1),
which doesn't actually need to quote many characters that
vanilla c-style quoting does. However, it shouldn't hurt, as
any implementation needs to be ready to handle quoted
strings anyway.
In addition to adding a test, we have to tweak a test which
blindly assumed that case (2) would always use
double-quotes, whether it needed to or not.

Many examples of git command invocation are given in asciidoc listing
blocks, which makes them monospaced and avoids further interpretation of
special characters. Some manpages make a list of examples, like:
git foo::
Run git foo.
git foo -q::
Use the "-q" option.
to quickly show many variants. However, they can sometimes be hard to
read, because they are shown in a proportional-width font (so, for
example, seeing the difference between "-- foo" and "--foo" can be
difficult).
This patch puts all such examples into backticks, which gives the
equivalent formatting to a listing block (i.e., monospaced and without
character interpretation).
As a bonus, this also fixes an example in the git-push manpage, in which
"git push origin :::" was accidentally considered a newly-indented list,
and not a list item with "git push origin :" in it.

generic function called "remove_sequencer_state" that various git

Apart from its central objective of calling into the picking
mechanism, pick_commits creates a sequencer directory, prepares a todo
list, and even acts upon the "--reset" subcommand. This makes for a
bad API since the central worry of callers is to figure out whether or
not any conflicts were encountered during the cherry picking. The
current API is like:
if (pick_commits(opts) < 0)
print "Something failed, we're not sure what"
So, change pick_commits so that it's only responsible for picking
commits in a loop and reporting any errors, leaving the rest to a new
function called pick_revisions. Consequently, the API of pick_commits
becomes much clearer:
act_on_subcommand(opts->subcommand);
todo_list = prepare_todo_list();
if (pick_commits(todo_list, opts) < 0)
print "Error encountered while picking commits"
Now, callers can easily call-in to the cherry-picking machinery by
constructing an arbitrary todo list along with some options.

Ever since v1.7.2-rc1~4^2~7 (revert: allow cherry-picking more than
one commit, 2010-06-02), a single invocation of "git cherry-pick" or
"git revert" can perform picks of several individual commits. To
implement features like "--continue" to continue the whole operation,
we will need to store some information about the state and the plan at
the beginning. Introduce a ".git/sequencer/head" file to store this
state, and ".git/sequencer/todo" file to store the plan. The head
file contains the SHA-1 of the HEAD before the start of the operation,
and the todo file contains an instruction sheet whose format is
inspired by the format of the "rebase -i" instruction sheet. As a
result, a typical todo file looks like:
pick 8537f0e submodule add: test failure when url is not configured
pick 4d68932 submodule add: allow relative repository path
pick f22a17e submodule add: clean up duplicated code
pick 59a5775 make copy_ref globally available
Since SHA-1 hex is abbreviated using an find_unique_abbrev(), it is
unambiguous. This does not guarantee that there will be no ambiguity
when more objects are added to the repository.
These two files alone are not enough to implement a "--continue" that
remembers the command-line options specified; later patches in the
series save them too.
These new files are unrelated to the existing .git/CHERRY_PICK_HEAD,
which will still be useful while committing after a conflict
resolution.

of the program. Although pick_commits, the current gatekeeper to the
cherry-pick machinery, checks the validity of the replay_opts
structure before before starting its operation, there will be multiple
entry points to the cherry-pick machinery in future. To futureproof
the code and catch these errors in one place, make sure that an
invalid replay_opts structure is not created by parse_args in the
first place. We still check the replay_opts structure for validity in
pick_commits, but this is an assert() now to emphasize that it's the

The current code uses a set of file-scope static variables to tell the
cherry-pick/ revert machinery how to replay the changes, and
initializes them by parsing the command-line arguments. In later
steps in this series, we would like to introduce an API function that
calls into this machinery directly and have a way to tell it what to
do. Hence, introduce a structure to group these variables, so that
the API can take them as a single replay_options parameter. The only
exception is the variable "me" -- remove it since it not an
independent option, and can be inferred from the action.
Unfortunately, this patch introduces a minor regression. Parsing
strategy-option violates a C89 rule: Initializers cannot refer to
variables whose address is not known at compile time. Currently, this
rule is violated by some other parts of Git as well, and it is
possible to get GCC to report these instances using the "-std=c89

Since the function's only caller ensures that a NULL argument isn't

1. Since the function doesn't use the global "commit" variable any
more, it won't need to change when we eliminate the global variable

2. Translators no longer need to localize an error message that will

In order to do partial commits, git-commit overlays a tree on the
cache and checks pathspecs against the result. Currently, the
overlaying is done using "prefix" which prevents relative pathspecs
with ".." and absolute pathspec from matching when they refer to
files not under "prefix" and absent from the index, but still in
the tree (i.e. files staged for removal).
The point of providing a prefix at all is performance optimization.
If we say there is no common prefix for the files of interest, then
we have to read the entire tree into the index.
But even if we cannot use the working directory as a prefix, we can
still figure out if there is a common prefix for all given paths,
and use that instead. The pathspec_prefix() routine from ls-files.c
does exactly that.
Any use of global variables is removed from pathspec_prefix() so
that it can be called from commit.c.

If the pager fails to run, git produces no output, e.g.:
$ GIT_PAGER=not-a-command git log
The error reporting fails for two reasons:
(1) start_command: There is a mechanism that detects errors during
execvp introduced in 2b541bf8 (start_command: detect execvp
failures early). The child writes one byte to a pipe only if
execvp fails. The parent waits for either EOF, when the
successful execvp automatically closes the pipe (see
FD_CLOEXEC in fcntl(1)), or it reads a single byte, in which
case it knows that the execvp failed. This mechanism is
incompatible with the workaround introduced in 35ce8622
(pager: Work around window resizing bug in 'less'), which
waits for input from the parent before the exec. Since both
the parent and the child are waiting for input from each
other, that would result in a deadlock. In order to avoid
that, the mechanism is disabled by closing the child_notifier
file descriptor.
(2) finish_command: The parent correctly detects the 127 exit
status from the child, but the error output goes nowhere,
since by that time it is already being redirected to the
child.
No simple solution for (1) comes to mind.
Number (2) can be solved by not sending error output to the pager.
Not redirecting error output to the pager can result in the pager
overwriting error output with standard output, however.
Since there is no reliable way to handle error reporting in the
parent, produce the output in the child instead.

git submodule add ../repo relative &&
...
git submodule sync relative &&
test "$(git config submodule.relative.url)" = "$submodurl/repo"
where $submodurl comes from the $TRASH_DIRECTORY the user
gave us. However, git will resolve symlinks when converting
the relative path into an absolute one, leading them to be
textually different (even though they point to the same
directory).

Because of backward compatibility we cannot change gitweb to always
use /etc/gitweb.conf (i.e. even if gitweb_config.perl exists). For
common system-wide settings we therefore need separate configuration
file: /etc/gitweb-common.conf.
Long description:
gitweb currently obtains configuration from the following sources:
1. per-instance configuration file (default: gitweb_conf.perl)
2. system-wide configuration file (default: /etc/gitweb.conf)
If per-instance configuration file exists, then system-wide
configuration is _not used at all_. This is quite untypical and
suprising behavior.
Moreover it is different from way git itself treats /etc/git.conf. It
reads in stuff from /etc/git.conf and then local repos can change or
override things as needed. In fact this is quite beneficial, because
it gives site admins a simple and easy way to give an automatic hint
to a repo about things the admin would like.
On the other hand changing current behavior may lead to the situation,
where something in /etc/gitweb.conf may interfere with unintended
interaction in the local repository. One solution would be to
_require_ to do explicit include; with read_config_file() it is now
easy, as described in gitweb/README (description introduced in this
commit).
But as J.H. noticed we cannot ask people to modify their per-instance
gitweb config file to include system-wide settings, nor we can require
them to do this.
Therefore, as proposed by Junio, for gitweb to have centralized config
elements while retaining backwards compatibility, introduce separate
common system-wide configuration file, by default /etc/gitweb-common.conf

On modern multi-core processors "make test" is often run in multiple jobs.
If one of them fails the test run does stop, but the concurrently running
tests finish their run. It is rather easy to find out which test failed by
doing a "ls -d t/trash*". But that only works when you don't use the "-i"
option to "make test" because you want to get an overview of all failing
tests. In that case all thrash directories are deleted end and the
information which tests failed is lost.
If one or more tests failed, print a list of them before the test summary:
failed test(s): t1000 t6500
fixed 0
success 7638
failed 3
broken 49
total 7723

Gitk can search for commits touching a specified path. The search text is
always treated as a regular expression, regardless of the matching option
selected (Exact, IgnCase, or Regexp). In particular, backslashes escape
the next character. This is inconvenient on Windows systems, where backslashes
are the norm for path specifiers, for example when copy/pasting from
Windows Explorer or a cmd shell -- these copy-pasted paths must be manually
modified in the gitk search text edit box before they will work.
This change uses the match option "Exact" to mean that a slash is a slash,
not part of a regular expression. Backslashes are converted to frontslashes
before searching, thus allowing easy copy/pasting of paths on Windows
systems. If the previous behaviour of "touching paths" search is desired,
simply select the "Regexp" search mode.
One potential drawback is that the default setting for the match option
($findtype in the code) is "Exact", and so this change alters the default
behaviour, which may confuse users and lead to bug reports.

Since 5024baa ([PATCH] Make gitk work when launched in a subdirectory,
2007-01-09), gitk has used 'git rev-parse --git-dir' to find the .git
directory. However, gitk still first checks for the $GIT_DIR
environment variable and that the value returned from git-rev-parse
does not point to a file. Since git-rev-parse does both of these
checks already, the checks can safely be removed from gitk. This makes
the gitdir procedure small enough to inline.
This cleanup introduces a UI regression in that the error message will
now be "Cannot find a git repository here." even in the case where
GIT_DIR points to a file, for which the error message was previously
"Cannot find the git directory \"%s\".". It should be noted, though,

This patch makes close_istream() into "close and de-allocate

call, but there's not much point in letting callers inspect
the istream after close. And this patch's semantics make us

git-config: Remove extra whitespaces
The "notemodify" fast-import command was introduced in commit a8dd2e7
(fast-import: Add support for importing commit notes, 2009-10-09)
The commit log has slightly different description than the added
documentation. The latter is somewhat confusing. "notemodify" is a
subcommand of "commit" command used to add a note for some commit.
Does this note annotate the commit produced by the "commit" command
or a commit given by it's committish parameter? Which notes tree
does it write notes to?
The exact meaning could be deduced with old description and some
notes machinery knowledge. But let's make it more obvious. This
command is used in a context like "commit refs/notes/test" to
add or rewrite an annotation for a committish parameter. So the
advised way to add notes in a fast-import stream is:
1) import some commits (optional)
2) prepare a "commit" to the notes tree:
2.1) choose notes ref, committer, log message, etc.
2.2) create annotations with "notemodify", where each can refer to
a commit being annotated via a branch name, import mark reference,
sha1 and other expressions specified in the Documentation.

1eb9486 HEAD@{1}: HEAD^: updating HEAD
However, we must also consider that some scripts may set
GIT_REFLOG_ACTION before calling reset, and we need to show
their reflog action (with our text appended). For example:
rebase -i (squash): updating HEAD
On top of that, we also set the ORIG_HEAD reflog action
(even though it doesn't generally exist). In that case, the
reset argument is somewhat meaningless, as it has nothing to
do with what's in ORIG_HEAD.
This patch changes the reset reflog code to show:
$GIT_REFLOG_ACTION: updating {HEAD,ORIG_HEAD}
as before, but only if GIT_REFLOG_ACTION is set. Otherwise,
show:
reset: moving to $rev
for HEAD, and:
reset: updating ORIG_HEAD
for ORIG_HEAD (this is still somewhat superfluous, since we
are in the ORIG_HEAD reflog, obviously, but at least we now
mention which command was used to update it).
While we're at it, we can clean up the code a bit:
- Use strbufs to make the message.
- Use the "rev" parameter instead of showing all options.
This makes more sense, since it is the only thing
impacting the writing of the ref.

When fetching an http URL, we first try fetching info/refs
with an extra "service" parameter. This will work for a
smart-http server, or a dumb server which ignores extra
parameters when fetching files. If that fails, we retry
without the extra parameter to remain compatible with dumb
servers which didn't like our first request.
If the server returned a "401 Unauthorized", indicating that
the credentials we provided were not good, there is not much
point in retrying. With the current code, we just waste an
extra round trip to the HTTP server before failing.
But as the http code becomes smarter about throwing away
rejected credentials and re-prompting the user for new ones
(which it will later in this series), this will become more
confusing. At some point we will stop asking for credentials
to retry smart http, and will be asking for credentials to
retry dumb http. So now we're not only wasting an extra HTTP
round trip for something that is unlikely to work, but we're
making the user re-type their password for it.

Currently the helper must somehow guess how many import statements to
read before it starts outputting its fast-export stream. This is
because the remote helper infrastructure runs fast-import only once,
so the helper is forced to output one stream for all import commands
it will receive. The only reason this worked in the past was because
only one ref was imported at a time.
Change the semantics of the import statement such that it matches
that of the push statement. That is, the import statement is followed
by a series of import statements that are terminated by a '\n'.

In other words, use fast-export --use-done-feature to add a 'done'
command at the end of streams passed to remote helpers' "import"
commands, and teach the remote helpers implementing "export" to use
the 'done' command in turn when producing their streams.
The trailing \n in the protocol signals the helper that the
connection is about to close, allowing it to do whatever cleanup
neccesary.
Previously, the connection would already be closed by the
time the trailing \n was to be written. Now that the remote-helper
protocol uses the new done command in its fast-import streams, this
is no longer the case and we can safely write the trailing \n.

If the new --done command line flag was passed on the command line
(or a "feature done" declaration included at the start of the stream),
make the 'done' command mandatory. So "git fast-import --done"'s
input format will be prefix-free, making errors easier to detect when
they show up as early termination at some convenient time of the
upstream of a pipe writing to fast-import.
Another possible application of the 'done' command would to be allow a
fast-import stream that is only a small part of a larger encapsulating
stream to be easily parsed, leaving the file offset after the "done\n"
so the other application can pick up from there. This patch does not

When a remote helper exports to a non-local git repo, the
steps are roughly:
1. fast-export into a local staging area; the set of
interesting refs is defined by what is in the fast-export
stream
2. git push from the staging area to the non-local repo
In the second step, we should explicitly push all refs, not
just matching ones. This will let us push refs that do not

When we want to push to a remote helper that has the

push and then feed them to fast-export.
However, the list of refs is actually a list of remote refs,
not local refs. The mapped local refs are included via the
peer_ref pointer. So when we add an argument to our
fast-export command line, we must be sure to use the local
peer_ref name (and if there is no local name, it is because
we are not actually sending that ref, or we may not even

These are all things one might expect to work in a helper
that is capable of handling multiple branches (which our
testgit helper in theory should be able to do, as it is
backed by git). All of these bugs are specific to the
import/export codepaths, so they don't affect helpers like
git-remote-curl that use fetch/push commands.
The first and fourth tests are about fetching and pushing
new refs, and demonstrate bugs in the git_remote_helpers
library (so they would be most likely to impact helpers for
other VCSs which import/export git).
The second test is about importing multiple refs; it
demonstrates a bug in git-remote-testgit, which is mostly
for exercising the test code. Therefore it probably doesn't
affect anyone in practice.
The third test demonstrates a bug in git's side of the
helper code when the upstream has added refs that we do not
have locally. This could impact git users who use remote
helpers to access foreign VCSs.
All of those bugs have fixes later in this series.
The fifth test is the most complex, and does not have a fix
in this series. It tests pushing a ref via the export
mechanism to a new name on the remote side (i.e.,
"git push $remote old:new").
The problem is that we push all of the work of generating
the export stream onto fast-export, but we have no way of
communicating to fast-export that this name mapping is
happening. So we tell fast-export to generate a stream with
the commits for "old", but we can't tell it to label them
all as "new".

This optimizes the "recency order" (see pack-heuristics.txt in
Documentation/technical/ directory) used to order objects within a
packfile in three ways:
- Commits at the tip of tags are written together, in the hope that
revision traversal done in incremental fetch (which starts by
putting them in a revision queue marked as UNINTERESTING) will see a
better locality of these objects;
- In the original recency order, trees and blobs are intermixed. Write
trees together before blobs, in the hope that this will improve
locality when running pathspec-limited revision traversal, i.e.
"git log paths...";
- When writing blob objects out, write the whole family of blobs that use
the same delta base object together, by starting from the root of the
delta chain, and writing its immediate children in a width-first
manner, in the hope that this will again improve locality when reading
blobs that belong to the same path, which are likely to be deltified

v3.0-rc6-71-g4dd1b49) packed with v1.7.6 and with this patch, counting how
large seeks are needed between adjacent accesses to objects in the pack,
and the result looks promising. The history has 2072052 objects, weighing
some 490MiB.

With the current pack heuristics, more than 30% of accesses have to
seek further than 300MB; the updated pack heuristics ensures that less

due to the fact that the updated heuristics does not mix blobs and
trees together.

As the index-pack command already walks objects in the delta chain
order, writing the blobs out in the delta chain order seems to
drastically improve the locality of access.
Note that a half-a-gigabyte packfile comfortably fits in the buffer cache,
and you would unlikely to see much performance difference on a modern and
reasonably beefy machine with enough memory and local disks. Benchmarking
with cold cache (or over NFS) would be interesting.

When executing an external shell script like `git foo` with a bad
shebang, e.g. "#!/usr/bin/not/existing", execvp returns 127 (ENOENT).
Since help_unknown_cmd proposes the use of all external commands similar
to the name of the "unknown" command, it suggests the just failed command
again. Stop it and give some advice to the user.

As resolve_ref() returns a static buffer that is local to the function,
the caller needs to be sure that it will not have any other calls to the
function before it uses the returned value, or store it away with a
strdup(). The code used old.path to record which branch it used to be on,
so that it can say between which branches the switch took place in the
reflog, but sometimes it failed to do so.

The SYNOPSIS sections of most commands that span several lines already
use [verse] to retain line breaks. Most commands that don't span
several lines seem not to use [verse]. In the HTML output, [verse]
does not only preserve line breaks, but also makes the section
indented, which causes a slight inconsistency between commands that
use [verse] and those that don't. Use [verse] in all SYNOPSIS sections
for consistency.
Also remove the blank lines from git-fetch.txt and git-rebase.txt to
align with the other man pages. In the case of git-rebase.txt, which
already uses [verse], the blank line makes the [verse] not apply to
the last line, so removing the blank line also makes the formatting
within the document more consistent.
While at it, add single quotes to 'git cvsimport' for consistency with
other commands.

Add support for dividing the refs of a single repository into multiple
namespaces, each of which can have its own branches, tags, and HEAD.
Git can expose each namespace as an independent repository to pull from
and push to, while sharing the object store, and exposing all the refs
to operations such as git-gc.
Storing multiple repositories as namespaces of a single repository
avoids storing duplicate copies of the same objects, such as when
storing multiple branches of the same source. The alternates mechanism
provides similar support for avoiding duplicates, but alternates do not
prevent duplication between new objects added to the repositories
without ongoing maintenance, while namespaces do.
To specify a namespace, set the GIT_NAMESPACE environment variable to
the namespace. For each ref namespace, git stores the corresponding
refs in a directory under refs/namespaces/. For example,
GIT_NAMESPACE=foo will store refs under refs/namespaces/foo/. You can
also specify namespaces via the --namespace option to git.
Note that namespaces which include a / will expand to a hierarchy of
namespaces; for example, GIT_NAMESPACE=foo/bar will store refs under
refs/namespaces/foo/refs/namespaces/bar/. This makes paths in
GIT_NAMESPACE behave hierarchically, so that cloning with
GIT_NAMESPACE=foo/bar produces the same result as cloning with
GIT_NAMESPACE=foo and cloning from that repo with GIT_NAMESPACE=bar. It
also avoids ambiguity with strange namespace paths such as
foo/refs/heads/, which could otherwise generate directory/file conflicts
within the refs directory.
Add the infrastructure for ref namespaces: handle the GIT_NAMESPACE
environment variable and --namespace option, and support iterating over
refs in a namespace.

The do_for_each_ref iteration function accepts a prefix and a trim, and
checks for the prefix on each ref before passing in that ref; it also
supports trimming off part of the ref before passing it. However,
do_for_each_ref used trim as the length of the prefix to check, ignoring
the actual length of the prefix. Switch to using prefixcmp, checking
the entire length of the prefix string, to properly support a trim value
different than the length of the prefix.
Several callers passed a prefix of "refs/" to filter out everything
outside of refs/, but a trim of 0 to avoid trimming off the "refs/"; the
trim of 0 meant that the filter of "refs/" no longer applied. Change
these callers to pass an empty prefix instead, to avoid changing the
existing behavior. Various callers count on this lack of filtering,
such as receive-pack which uses add_extra_ref to add alternates as refs
named ".have"; adding filtering would break that, causing
t5501-fetch-push-alternates.sh to fail. That lack of filtering doesn't
currently have any other effect, since the loose ref functions can never
supply refs outside of "refs/", and packed-refs will not normally
include such refs unless manually edited.

Enhance usability of 'blob_plain' view protection against XSS attacks
(enabled by setting $prevent_xss to true) by serving contents inline
as safe 'text/plain' mimetype where possible, instead of serving with
"Content-Disposition: attachment" to make sure they don't run in
gitweb's security domain.
This patch broadens downgrading to 'text/plain' further, to any
*/*+xml mimetype. This includes:
application/xhtml+xml (*.xhtml, *.xht)
application/atom+xml (*.atom)
application/rss+xml (*.rss)
application/mathml+xm (*.mathml)
application/docbook+xml (*.docbook)
image/svg+xml (*.svg, *.svgz)
Probably most useful is serving XHTML files as text/plain in
'blob_plain' view, directly viewable.
Because file with 'image/svg+xml' mimetype can be compressed SVGZ
file, we have to check if */*+xml really is text file, via '-T $fd'.

One of mechanism enabled by setting $prevent_xss to true is 'blob_plain'
view protection. With XSS prevention on, blobs of all types except a
few known safe ones are served with "Content-Disposition: attachment" to
make sure they don't run in our security domain.
Instead of serving text/* type files, except text/plain (and including
text/html), as attachements, downgrade it to text/plain. This way HTML
pages in 'blob_plain' (raw) view would be displayed in browser, but
safely as a source, and not asked to be saved.

The user-supplied command spawned by 'submodule foreach' loses its
connection to the original standard input. Instead, it is connected to the
output of a pipe within the git-submodule script. The user-supplied
command supplied to 'submodule foreach' is spawned within a while loop
which is being piped into. Due to the way shells implement piping output
to a while loop, a subshell is created with its standard input attached to
the output of the pipe. This results in all of the commands executed
within the while loop to have their stdins modified in the same way,
including the user-supplied command.
This can cause a problem if the command requires reading from stdin or if
it changes its behavior based on whether stdin is a tty or not. For
example, this problem was noticed when trying to execute the following:
git submodule foreach git shortlog --since=two.weeks.ago
which printed a message about entering the first submodule and produced no
further output and exited with a status of zero. In this case, shortlog
detected that it was not connected to a tty, and since no revision was
supplied as an argument, it attempted to read the list of revisions from
standard input. Instead, it slurped up the list of submodules that was
being piped to the enclosing while loop and caused that loop to end early
without processing the remaining submodules.
Work around this behavior by saving the original standard input file
descriptor before the while loop, and restoring it when spawning the
user-supplied command.
This fixes the tests in t7407.

is all gone after the clean-up procedure defined by test_when_finished is

Update test_run_ which is the workhorse of running a test script
called from test_expect_success and test_expect_failure, so that we do not
run clean-up script defined with test_when_finished when a test that is
expected to succeed fails under the --immediate mode.

When a non-existent branch was specified to be rebased, the complete

The error message was introduced recently by 4ac5356c (rebase: give a

acceptable because the usage text was just two lines. But 45e2acf3

As explained in v1.7.3-rc0~13^2 (Work around em-dash handling in newer
AsciiDoc, 2010-08-23), if double dashes in names of commands are not
escaped, AsciiDoc renders them as em dashes.
While fixing that, spell the command name as "git sh-i18n--envsubst"
(2 words) instead of emphasizing the name of the binary (one
hyphenated name) and format it in italics.
The double-dash in the title should be escaped, too, to avoid spurious
em dashes in the header:
.TH "GIT\-SH\-I18N\(emENVSUB" "1" "06/26/2011" "Git 1\&.7\&.6" "Git Manual"
AsciiDoc 8.6.4 with DocBook XSL 1.76.0-RC1 copes fine and writes
"GIT\-SH\-I18N\-\-ENVSUB" even without this change, which is why it
was missed before.

AsciiDoc versions since 5.0.6 treat a double-dash surrounded by spaces
(outside of verbatim environments) as a request to insert an em dash.
Such versions also treat the three-character sequence "\--", when not
followed by another dash, as a request to insert two literal minus
signs. Thus from time to time there have been patches to add
backslashes to AsciiDoc markup to escape double-dashes that are meant
to be represent '--' characters used literally on the command line;
see v1.4.0-rc1~174, Fix up docs where "--" isn't displayed correctly,
2006-05-05, for example.
AsciiDoc 6.0.3 (2005-04-20) made life harder by also treating
double-dashes without surrounding whitespace as markup for an em dash,
though only when formatting for backends other than the manpages
(e.g., HTML). Many pages needed to be changed to use a backslash
before the "--" in names of command-line flags like "--add" (see
v0.99.6~37, Update tutorial, 2005-08-30).
AsciiDoc 8.3.0 (2008-11-29) refined the em-dash rule to avoid that
requirement. Double-dashes without surrounding spaces are not
rendered as em dashes any more unless bordered on both sides by
alphanumeric characters. The unescaped markup for option names (e.g.,
"--add") works fine, and many instances of this style have leaked into
Documentation/; git's HTML documentation contains many spurious em
dashes when formatted by an older toolchain. (This patch will not
change that.)
The upshot: "--" as an isolated word and in phrases like "git
web--browse" must be escaped if it is not to be rendered as an em dash
by current asciidoc. Use "\--" to avoid such misformatting in
sentences in which "--" represents a literal double-minus command line
argument that separates options and revs from pathspecs, and use
"{litdd}" in cases where the double-dash is embedded in the command
name. The latter is just for consistency with v1.7.3-rc0~13^2 (Work
around em-dash handling in newer AsciiDoc, 2010-08-23).

When "git submodule add $path" is run to add a subdirectory $path to the
superproject, and $path is already the top of the working tree of the
submodule repository, the command created submodule.$path.url entry in the
configuration file in the superproject. However, when adding a repository
$URL that is outside the respository of the superproject to $path that
does not exist (yet) with "git submodule add $URL $path", the command
forgot to set it up.
The user is expressing the interest in the submodule and wants to keep a
checkout, the "submodule add" command should consistently set up the
submodule.$path.url entry in either case.
As a result "git submodule init" can't simply skip the initialization of
those submodules for which it finds an url entry in the git./config
anymore. That lead to problems when adding a submodule (which now sets the
url), add the "update" setting to .gitmodules and expect init to copy that
into .git/config like it is done in t7406. So change init to only then
copy the "url" and "update" entries when they don't exist yet in the
.git/config and do nothing otherwise.

However, it did so by unconditionally registering submodule.$name.url to
every submodule in the project, even the ones that the user has never
showed interest in at all by running 'git submodule init' command. This
caused subsequent 'git submodule update' to start cloning/updating submodules
that are not interesting to the user at all.

The --include-untracked option acts like the normal "git stash save" but
also adds all untracked files in the working directory to the stash and then
calls "git clean --force --quiet" to restore the working directory to a
pristine state.
This is useful for projects that need to run release scripts. With this
option, the release scripts can be from the main working directory so one
does not have to maintain a "clean" directory in parallel just for
releasing. Basically the work-flow becomes:
$ git tag release-1.0
$ git stash --include-untracked
$ make release
$ git clean -f
$ git stash pop
"git stash" alone is not enough in this case--it leaves untracked files
lying around that might mess up a release process that expects everything to
be very clean or might let a release succeed that should actually fail (due
to a new source file being created that hasn't been committed yet).

Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any

we do any other operations.
In many cases, this is a minor convenience over something
like:
git clone git://...

But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.
It also provides a mechanism for passing information to remote

The error handling for git_config is somewhat confusing. We
collect errors from running git_config_from_file on the
various config files and carefully pass them back up. But
the two odd things are:
1. We actually die on most errors in git_config_from_file.
In fact, the only error we actually pass back up is if
fopen() fails on the file.
2. Most callers of git_config do not check the error
return at all, but will continue if git_config reports
an error.
When the code for "git -c core.foo=bar" was added, it
dutifully passed errors up the call stack, only for them to
be eventually ignored. This makes it inconsistent with the
file-parsing code, which will die when it sees malformed
config. And it's somewhat unsafe, because it means an error
in parsing a typo like:
git -c clean.requireforce=ture clean
will continue the command, ignoring the config the user
tried to give.

Git-archive will guess a format from the output filename if
no format is explicitly given. The current function just
hardcodes "zip" to the zip format, and leaves everything
else NULL (which will default to tar). Since we are about
to add user-specified formats, we need to be more flexible.
The new rule is "if a filename ends with a dot and the name
of a format, it matches that format". For the existing "tar"
and "zip" formats, this is identical to the current
behavior. For new user-specified formats, this will do what
the user expects if they name their formats appropriately.
Because we will eventually start matching arbitrary
user-specified extensions that may include dots, the strrchr
search for the final dot is not sufficient. We need to do an
actual suffix match with each extension.

The process for guessing an archive output format based on
the filename is something like this:
a. parse --output in cmd_archive; check the filename
against a static set of mapping heuristics (right now
it just matches ".zip" for zip files).
b. if found, stick a fake "--format=zip" at the beginning
of the arguments list (if the user did specify a
--format manually, the later option will override our
fake one)
c. if it's a remote call, ship the arguments to the remote
(including the fake), which will call write_archive on
their end
d. if it's local, ship the arguments to write_archive
locally
There are two problems:
1. The set of mappings is static and at too high a level.
The write_archive level is going to check config for
user-defined formats, some of which will specify
extensions. We need to delay lookup until those are
parsed, so we can match against them.
2. For a remote archive call, our set of mappings (or
formats) may not match the remote side's. This is OK in
practice right now, because all versions of git
understand "zip" and "tar". But as new formats are
added, there is going to be a mismatch between what the
client can do and what the remote server can do.
To fix (1), this patch refactors the location guessing to
happen at the write_archive level, instead of the
cmd_archive level. So instead of sticking a fake --format
field in the argv list, we actually pass a "name hint" down
the callchain; this hint is used at the appropriate time to
guess the format (if one hasn't been given already).
This patch leaves (2) unfixed. The name_hint is converted to
a "--format" option as before, and passed to the remote.
This means the local side's idea of how extensions map to
formats will take precedence.
Another option would be to pass the name hint to the remote
side and let the remote choose. This isn't a good idea for
two reasons:
1. There's no room in the protocol for passing that
information. We can pass a new argument, but older
versions of git on the server will choke on it.
2. Letting the remote side decide creates a silent
inconsistency in user experience. Consider the case
that the locally installed git knows about the "tar.gz"
format, but a remote server doesn't.
Running "git archive -o foo.tar.gz" will use the tar.gz
format. If we use --remote, and the local side chooses
the format, then we send "--format=tar.gz" to the
remote, which will complain about the unknown format.
But if we let the remote side choose the format, then
it will realize that it doesn't know about "tar.gz" and
output uncompressed tar without even issuing a warning.

However, to facilitate runtime-configurable archivers

As a convenience, we also provide an opaque data pointer in

Earlier 7974843 (compat/cygwin.c: make runtime detection of lstat/stat
lessor impact, 2008-10-23) fixed the low-level "do we use cygwin specific
hacks for stat/lstat?" logic not to call into git_default_config() from
random codepaths that are typically very late in the program, to prevent
the call from potentially overwriting other variables that are initialized
from the configuration.
However, it forgot that on Cygwin, trust-executable-bit should default to
true.
Noticed by J6t, confirmed by Ramsay Jones, and the brown paper bag is on

When on-demand mode was active examining the new commits just fetched in
the superproject (to check if they record commits for submodules which are
not downloaded yet) wasn't done recursively. Because of that fetch did not
recursively fetch submodules living in subdirectories even when it should
have.
Fix that by adding the RECURSIVE flag to the diff_options used to check
the new commits and avoid future regressions in this area by moving a

Until now, "git tag -l foo* bar*" would silently ignore the
second argument, showing only refs starting with "foo". It's
not just unfriendly not to take a second pattern; we
actually generated subtly wrong results (from the user's
perspective) because some of the requested tags were
omitted.
This patch allows an arbitrary number of patterns on the

While we're tweaking the documentation, let's also make it

Consider this graph:
D---E (topic, HEAD)
/ /
A---B---C (master)
\
F (topic2)
and the following three commands:
1. git rebase -i -p A
2. git rebase -i -p --onto F A
3. git rebase -i -p B
Currently, (1) and (2) will pick B, D, C, and E onto A and F,
respectively. However, (3) will only pick D and E onto B, but not C,
which is inconsistent with (1) and (2). As a result, we cannot modify C
during the interactive-rebase.
The current behavior also creates a bug if we do:
4. git rebase -i -p C
In (4), E is never picked. And since interactive-rebase resets "HEAD"
to "onto" before picking any commits, D and E are lost after the
interactive-rebase.
This patch fixes the inconsistency and bug by ensuring that all children
of upstream are always picked. This essentially reverts the commit:
d80d6bc146
When compiling the todo list, commits reachable from "upstream" should
never be skipped under any conditions. Otherwise, we lose the ability
to modify them like (3), and create a bug like (4).
Two of the tests contain a scenario like (3). Since the new behavior
added more commits for picking, these tests need to be updated to
account for the additional pick lines. A new test has also been added
for (4).

When we run tests under valgrind, we symlink anything
executable that starts with git-* or test-* into a special
valgrind bin directory, and then make that our
GIT_EXEC_PATH.
However, shell libraries like git-sh-setup do not have the
executable bit marked, and did not get symlinked. This
means that any test looking for shell libraries in our
exec-path would fail to find them, even though that is a
fine thing to do when testing against a regular git build
(or in a git install, for that matter).
t2300 demonstrated this problem. The fix is to symlink these

On Cygwin, this fixes a test failure in t3301-notes.sh (test 98,
"git notes copy --for-rewrite (disabled)").
The test failure is caused by a recursive call to git_config() which
has the effect of skipping to the end-of-file while processing the
"notes.rewriteref" config variable. Thus, any config variables that
appear after "notes.rewriteref" are simply ignored by git_config().
Also, we note that the original FILE handle is leaked as a result
of the recursive call.
The recursive call to git_config() is due to the "schizophrenic stat"
functions on cygwin, where one of two different implementations of
the l/stat functions is selected lazily, depending on some config
variables.
In this case, the init_copy_notes_for_rewrite() function calls
git_config() with the notes_rewrite_config() callback function.
This callback, while processing the "notes.rewriteref" variable,
in turn calls string_list_add_refs_by_glob() to process the
associated ref value. This eventually leads to a call to the
get_ref_dir() function, which in turn calls stat(). On cygwin,
the stat() macro leads to an indirect call to cygwin_stat_stub()
which, via init_stat(), then calls git_config() in order to
determine which l/stat implementation to bind to.
In order to solve this problem, we modify git_config() so that the
global state variables used by the config reading code is packaged
up and managed on a local state stack.

The 'forced modes' test fails on cygwin because the post-update
hook loses it's executable bit when copied from the templates
directory by git-init. The template loses it's executable bit
because the lstat() function resolves to the "native Win32 API"
implementation.
This call to lstat() happens after git-init has set the "git_dir"
(so has_git_dir() returns true), but before the configuration has
been fully initialised. At this point git_config() does not find
any config files to parse and returns 0. Unfortunately, the code
used to determine the cygwin l/stat() function bindings did not
check the return from git_config() and assumed that the config
was complete and accessible once "git_dir" was set.
In order to fix the test, we simply change the binding code to
test the return value from git_config(), to ensure that it actually
had config values to read, before determining the requested binding.

Test t7606-merge-custom.sh fails on cygwin when git-merge fails
with an "Could not find merge strategy 'theirs'" error, despite
the test correctly preparing an (executable) git-merge-theirs
script.
The cause of the failure is the mis-detection of the executable
status of the script, by the is_executable() function, while the
load_command_list() function is searching the path for additional
merge strategy programs.
Note that the l/stat() "functions" on cygwin are somewhat
schizophrenic (see commits adbc0b6, 7faee6b and 7974843), and
their behaviour depends on the timing of various git setup and
config function calls. In particular, until the "git_dir" has
been set (have_git_dir() returns true), the real cygwin (POSIX
emulating) l/stat() functions are called. Once "git_dir" has
been set, the "native Win32 API" implementations of l/stat()
may, or may not, be called depending on the setting of the
core.filemode and core.ignorecygwinfstricks config variables.
We also note that, since commit c869753, core.filemode is forced
to false, even on NTFS, by git-init and git-clone. A user (or a
test) can, of course, reset core.filemode to true explicitly if
the filesystem supports it (and he doesn't use any problematic
windows software). The test-suite currently runs all tests on
cygwin with core.filemode set to false.
Given the above, we see that the built-in merge strategies are
correctly detected as executable, since they are checked for
before "git_dir" is set, whereas all custom merge strategies are
not, since they are checked for after "git_dir" is set.
In order to fix the mis-detection problem, we change the code in
is_executable() to re-use the conditional WIN32 code section,
which actually looks at the content of the file to determine if
the file is executable. On cygwin we also make the additional
code conditional on the executable bit of the file mode returned
by the initial stat() call. (only the real cygwin function would
set the executable bit in the file mode.)

The archive command does three things during its
initialization phase:
1. parse command-line options
2. setup the git directory
3. read config
During phase (1), if we see any options that do not require
a git directory (like "--list"), we handle them immediately
and exit, making it safe to abort step (2) if we are not in
a git directory.
Step (3) must come after step (2), since the git directory
may influence configuration. However, this leaves no
possibility of configuration from step (3) impacting the
command-line options in step (1) (which is useful, for
example, for supporting user-configurable output formats).
Instead, let's reorder this to:
1. setup the git directory, if it exists
2. read config
3. parse command-line options
4. if we are not in a git repository, die
This should have the same external behavior, but puts
configuration before command-line parsing.

Introduce a "max_off" field in struct sliding_view, roughly
representing a maximum number of bytes that can be read from "file".
If it is set to a nonnegative integer, a call to move_window()
attempting to put the right endpoint beyond that offset will return
an error instead.
The idea is to use this when applying Subversion-format deltas to
prevent reads past the end of the preimage (which has known length).
Without such a check, corrupt deltas would cause svn-fe to block
indefinitely when data in the input pipe is exhausted.

"git submodule update" stops at the first error and gives control
back to the user. Only after the user fixes the problematic
submodule and runs "git submodule update" again, the second error
is found. And the user needs to repeat until all the problems are
found and fixed one by one. This is tedious.
Instead, the command can remember which submodules it had trouble with,
continue updating the ones it can, and report which ones had errors at
the end. The user can run "git submodule update", find all the ones that
need minor fixing (e.g. working tree was dirty) to fix them in a single
pass. Then another "git submodule update" can be run to update all.
Note that the problematic submodules are skipped only when they are to
be integrated with a safer value of submodule.<name>.update option,
namely "checkout". Fixing a failure in a submodule that uses "rebase" or
"merge" may need an involved conflict resolution by the user, and
leaving too many submodules in states that need resolution would not
reduce the mental burden on the user.

When looking for commits that contain other commits (e.g.,
via "git tag --contains"), we can end up traversing useless
portions of the graph. For example, if I am looking for a
tag that contains a commit made last week, there is not much
point in traversing portions of the history graph made five
years ago.
This optimization can provide massive speedups. For example,
doing "git tag --contains HEAD~200" in the linux-2.6
repository goes from:
real 0m5.302s
user 0m5.116s
sys 0m0.184s
to:
real 0m0.030s
user 0m0.020s
sys 0m0.008s
The downside is that we will no longer find some answers in
the face of extreme clock skew, as we will stop the
traversal early when seeing commits skewed too far into the
past.
Name-rev already implements a similar optimization, using a
"slop" of one day to allow for a certain amount of clock
skew in commit timestamps. This patch introduces a
"core.clockskew" variable, which allows specifying the
allowable amount of clock skew in seconds. For safety, it
defaults to "none", causing a full traversal (i.e., no
change in behavior from previous versions).

When we want to know if commit A contains commit B (or any
one of a set of commits, B through Z), we generally
calculate the merge bases and see if B is a merge base of A
(or for a set, if any of the commits B through Z have that
property).
When we are going to check a series of commits A1 through An
to see whether each contains B (e.g., because we are
deciding which tags to show with "git tag --contains"), we
do a series of merge base calculations. This can be very
expensive, as we repeat a lot of traversal work.
Instead, let's leverage the fact that we are going to use
the same --contains list for each tag, and mark areas of the
commit graph is definitely containing those commits, or
definitely not containing those commits. Later tags can then
stop traversing as soon as they see a previously calculated
answer.
This sped up "git tag --contains HEAD~200" in the linux-2.6
repository from:
real 0m15.417s
user 0m15.197s

Update zlib_post_call() that adjusts the wrapper's notion of avail_in and
avail_out to what came back from zlib, so that the callers can feed
buffers larger than than 4GB to the API.
When underlying inflate/deflate stopped processing because we fed a buffer
larger than 4GB limit, detect that case, update the state variables, and
let the zlib function work another round.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The size of objects we read from the repository and data we try to put
into the repository are represented in "unsigned long", so that on larger
architectures we can handle objects that weigh more than 4GB.
But the interface defined in zlib.h to communicate with inflate/deflate
limits avail_in (how many bytes of input are we calling zlib with) and
avail_out (how many bytes of output from zlib are we ready to accept)
fields effectively to 4GB by defining their type to be uInt.
In many places in our code, we allocate a large buffer (e.g. mmap'ing a
large loose object file) and tell zlib its size by assigning the size to
avail_in field of the stream, but that will truncate the high octets of
the real size. The worst part of this story is that we often pass around
z_stream (the state object used by zlib) to keep track of the number of
used bytes in input/output buffer by inspecting these two fields, which
practically limits our callchain to the same 4GB limit.
Wrap z_stream in another structure git_zstream that can express avail_in
and avail_out in unsigned long. For now, just die() when the caller gives
a size that cannot be given to a single zlib call. In later patches in the
series, we would make git_inflate() and git_deflate() internally loop to
give callers an illusion that our "improved" version of zlib interface can
operate on a buffer larger than 4GB in one go.

v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are

intuitive for webmasters by checking whether the ctags/<label> under

association to <label>) before treating it as one.
With that change, after putting '$feature{'ctags'}{'default'} = [1];'
in your $GITWEB_CONFIG, you could do
echo Linux >.git/ctags/linux
and gitweb would treat that as a request to tag the current repository
with the Linux tag, instead of the previous behavior of writing an
error page embedded in the projects list that triggers error messages
from Chromium and Firefox about malformed XML.
Unfortunately the pattern (\d+) used to match numbers is too loose,
and the "XML declaration allowed only at the start of the document"

"Linux" in the example above. Fix it by tightening the pattern to

This renames the function (and negates its return value) to detect if we
are looking at the experimental format, and move the code around in its
caller which used to do "if we are looing at legacy, do this special case,
otherwise the normal case is this". The codepath to read from the loose

In most cases, fetching the remote HEAD explicitly is
unnecessary. It's just a symref pointing to a branch which
we are already fetching, so we will already ask for its sha1.
However, if the remote has a detached HEAD, things are less
certain. We do not ask for HEAD's sha1, but we do try to
write it into a local detached HEAD. In most cases this is
fine, as the remote HEAD is pointing to some part of the
history graph that we will fetch via the refs.
But if the remote HEAD points to an "orphan" commit (one
which was is not an ancestor of any refs), then we will not
have the object, and update_ref will complain when we try to
write the detached HEAD, aborting the whole clone.
This patch makes clone always explicitly ask the remote for
the sha1 of its HEAD commit. In the non-detached case, this
is a no-op, as we were going to ask for that sha1 anyway. In
the regular detached case, this will add an extra "want" to
the protocol negotiation, but will not change the history
that gets sent. And in the detached orphan case, we will
fetch the orphaned history so that we can write it into our
local detached HEAD.

Adding a submodule with a relative repository path did only succeed when

getenv() on Windows looks up environment variables in a case-insensitive
manner. Even though all documentations claim that the environment is
case-insensitive, it is possible for applications to pass an environment
to child processes that has variables that differ only in case. Bash on
Windows does this, for example, and sh-i18n--envsubst depends on this
behavior.
With this patch environment variables are first looked up in a
case-sensitive manner; only if this finds nothing, the system's getenv() is
used as a fallback.

We want to use static lookup_env() in a subsequent change.
At first sight, this change looks innocent. But it is not due to the
#undef getenv. There is one caller of getenv between the old location and
the new location whose behavior could change. But as can be seen from the
defintion of mingw_getenv, the behavior for this caller does not change
substantially.
To ensure consistent behavior in the future, change all getenv callers
in mingw.c to use mingw_getenv.
With this patch, this is not a big deal, yet, but with the subsequent
change, where we teach getenv to do a case-sensitive lookup, the behavior
of all call sites is changed.

This finally gets rid of the inefficient verify-pack implementation that
walks objects in the packfile in their object name order and replaces it
with a call to index-pack --verify. As a side effect, it also removes
packed_object_info_detail() API which is rather expensive.
As this changes the way errors are reported (verify-pack used to rely on
the usual runtime error detection routine unpack_entry() to diagnose the
CRC errors in an entry in the *.idx file; index-pack --verify checks the
whole *.idx file in one go), update a test that expected the string "CRC"
to appear in the error message.

The histogram produced by "verify-pack -v" always had an artificial
limit of 50, but index-pack knows what the maximum delta depth is, so
we do not have to limit it.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The "index-pack" machinery already has almost enough knowledge to produce
the same output as "verify-pack -v". Fill small gaps in its bookkeeping,
and teach it to show what it knows.
Add a few more command line options that do not have to be advertised to
the end users. They will be used internally when verify-pack calls this.
The eventual goal is to remove verify-pack implementation and redo it as a
thin wrapper around the index-pack, so that we can remove the rather
expensive packed_object_info_detail() API.
This still does not do the delta-chain-depth histogram yet but that part
is easy.

When create a new branch, we fed "refs/heads/<proposed name>" as a string
to get_sha1() and expected it to fail when a branch already exists.
The right way to check if a ref exists is to check with resolve_ref().
A naïve solution that might appear attractive but does not work is to
forbid slashes in get_describe_name() but that will not work. A describe
name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part
comes from a original tag name used in the repository the user ran the
describe command. A sick user could have a confusing hierarchical tag
whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar")
to generate a describe name "refs/heads/foobar-6-g02ac983", and we should
be able to use that name to refer to the object whose name is 02ac983.

Commit 431d6e7b (grep: enable threading for context line printing)
split the printing of the "--\n" mark between results from different
files out into two places: show_line() in grep.c for the non-threaded
case and work_done() in builtin/grep.c for the threaded case. Commit
55f638bd (grep: Colorize filename, line number, and separator) updated
the former, but not the latter, so the separators between files are
not colored if threads are used.
This patch merges the two. In the threaded case, hunk marks are now
printed by show_line() for every file, including the first one, and the
very first mark is simply skipped in work_done(). This ensures that the
output is properly colored and works just as well.

The guess_remote_head function tries to figure out where a
remote's HEAD is pointing by comparing the sha1 of the
remote's HEAD with the sha1 of various refs found on the
remote. However, we were too liberal in matching refs, and
would match tags or remote tracking branches, even though
these things could not possibly be referenced by the HEAD
symbolic ref (since git will detach when checking them out).
As a result, a clone of a remote repository with a detached
HEAD might write "refs/tags/*" into our local HEAD, which is
bogus. The resulting HEAD should be detached.
The other related code path is remote.c's get_head_names()
(which is used for, among other things, "set-head -a"). This was
not affected, however, as that function feeds only refs from
refs/heads to guess_remote_head.

We didn't test this setup at all, and doing so reveals a few
bugs:
1. Cloning a repository with an orphaned detached HEAD
(i.e., one that points to history that is not
referenced by any ref) will fail.
2. Cloning a repository with a detached HEAD that points
to a tag will cause us to write a bogus "refs/tags/..."
ref into the HEAD symbolic ref. We should probably
detach instead.
3. Cloning a repository with a detached HEAD that points
to a branch will cause us to checkout that branch. This
is a known limitation of the git protocol (we have to
guess at HEAD's destination, since the symref contents
aren't shown to us). This test serves to document the
desired behavior, which can only be achieved once the
git protocol learns to share symref information.

Once the cookie file has been created, it can be passed to git with, e.g.

A negative return from the unpack callback function usually means unpack
failed for the entry and signals the unpack_trees() machinery to fail the
entire merge operation, immediately and there is no other way for the
callback to tell the machinery to exit early without reporting an error.
This is what we usually want to make a merge all-or-nothing operation, but
the machinery is also used for diff-index codepath by using a custom
unpack callback function. And we do sometimes want to exit early without
failing, namely when we are under --quiet and can short-cut the diff upon
finding the first difference.
Add "exiting_early" field to unpack_trees_options structure, to signal the
unpack_trees() machinery that the negative return value is not signaling
an error but an early return from the unpack_trees() machinery. As this by
definition hasn't unpacked everything, discard the resulting index just
like the failure codepath.

Commit 2cfe8a6 (diff --quiet: disable optimization when

cases by disabling the optimization when a filter is

The easiest way to make this test pass is to just update expected

check whether 'git grep -E -F -G' is different from 'git grep -E -G -F'.
To check that, let's change pattern to "a+b*c". This should return
different match for -G, -F and -E.
I also made two small tweaks to the tests. First, I added path "ab" to
all calls to future-proof tests. Second, I updated last two tests to
better show that 'git grep -P -E' is different from 'git grep -E -P'.

Because we're already at the final result on the detached

If there is a possibility that your logic could take longer to execute
than the interval time, it is recommended that you recursively call a
named function using window.setTimeout rather than window.setInterval.
Therefore instead of using setInterval as an alternate way of invoking
handleResponse (because some web browsers call onreadystatechange only
once per each distinct state, and not for each server flush), use
setTimeout and reset it from handleResponse. As a bonus this allows
us to get rid of timer if it turns out that web browser calls
onreadystatechange on each server flush.

This introduces an API to plug custom filters to an input stream.
The caller gets get_stream_filter("path") to obtain an appropriate
filter for the path, and then uses it when opening an input stream
via open_istream(). After that, the caller can read from the stream
with read_istream(), and close it with close_istream(), just like an
unfiltered stream.
This only adds a "null" filter that is a pass-thru filter, but later
changes can add LF-to-CRLF and other filters, and the callers of the
streaming API do not have to change.

In older versions of git, we used rfc822 header folding to
indicate that the original subject line had multiple lines
in it. But since a1f6baa (format-patch: wrap long header
lines, 2011-02-23), we now use header folding whenever there
is a long line.
This means that "git am" cannot trust header folding as a
sign from format-patch that newlines should be preserved.
Instead, format-patch needs to signal more explicitly that
the newlines are significant. This patch does so by
rfc2047-encoding the newlines in the subject line. No
changes are needed on the "git am" end; it already decodes
the newlines properly.

We have a pretty_print_context representing the parameters
for a pretty-print session, but we did not use it uniformly.
As a result, functions kept growing more and more arguments.
Let's clean this up in a few ways:
1. All pretty-print pp_* functions now take a context.
This lets us reduce the number of arguments to these
functions, since we were just passing around the
context values separately.
2. The context argument now has a cmit_fmt field, which
was passed around separately. That's one less argument
per function.
3. The context argument always comes first, which makes
calling a little more uniform.
This drops lines from some callers, and adds lines in a few
places (because we need an extra line to set the context's
fmt field). Overall, we don't save many lines, but the lines
that are there are a lot simpler and more readable.

Without the "-k" option, mailinfo will convert a folded
subject header like:
Subject: this is a
subject that doesn't
fit on one line
into a single line. With "-k", however, we assumed that
these newlines were significant and represented something
that the sending side would want us to preserve.
For messages created by format-patch, this assumption was
broken by a1f6baa (format-patch: wrap long header lines,
2011-02-23). For messages sent by arbitrary MUAs, this was
probably never a good assumption to make, as they may have
been folding subjects in accordance with rfc822's line
length recommendations all along.
This patch now joins folded lines with a single whitespace
character. This treats header folding purely as a syntactic

Commit a1f6baa (format-patch: wrap long header lines,
2011-02-23) changed format-patch's behavior with respect to
long header lines, but made no accompanying changes to the
receiving side. It was thought that "git am" would handle
these folded subjects fine, but there is a regression when
using "am -k".
Let's add a test documenting this. While we're at it, let's
give more complete test coverage to document what should be
happening in each case. We test three types of subjects:
a short one, one long enough to require wrapping, and a
multiline subject. For each, we test these three
combinations:
format-patch | am
format-patch -k | am
format-patch -k | am -k
We don't bother testing "format-patch | am -k", which is
nonsense (you will be adding in [PATCH] cruft to each
subject).
This reveals the regression above (long subjects have
linebreaks introduced via "format-patch -k | am -k"),
as well as an existing non-optimal behavior (multiline
subjects are not preserved using "-k").

The read_in_full function repeatedly calls read() to fill a
buffer. If the first read() returns an error, we notify the
caller by returning the error. However, if we read some data
and then get an error on a subsequent read, we simply return
the amount of data that we did read, and the caller is
unaware of the error.
This makes the tradeoff that seeing the partial data is more
important than the fact that an error occurred. In practice,
this is generally not the case; we care more if an error
occurred, and should throw away any partial data.
I audited the current callers. In most cases, this will make
no difference at all, as they do:
if (read_in_full(fd, buf, size) != size)
error("short read");
However, it will help in a few cases:
1. In sha1_file.c:index_stream, we would fail to notice
errors in the incoming stream.
2. When reading symbolic refs in resolve_ref, we would
fail to notice errors and potentially use a truncated
ref name.
3. In various places, we will get much better error
messages. For example, callers of safe_read would
erroneously print "the remote end hung up unexpectedly"
instead of showing the read error.

Commit 13fc2c1 (remote: disallow some nonsensical option
combinations, 2011-03-30) made it impossible to use "remote
add -t foo --mirror". The argument was that specifying
specific branches is useless because:
1. Push mirrors do not want a refspec at all.
2. The point of fetch mirroring is to use a broad refspec
like "refs/*", but using "-t" overrides that.
Point (1) is valid; "-t" with push mirrors is useless. But
point (2) ignored another side effect of using --mirror: it
fetches the refs directly into the refs/ namespace as they
are found upstream, instead of placing them in a
separate-remote layout.
So 13fc2c1 was overly constrictive, and disallowed
reasonable specific-branch mirroring, like:
git remote add -t heads/foo -t heads/bar --mirror=fetch
which makes the local "foo" and "bar" branches direct
mirrors of the remote, but does not fetch anything else.
This patch restores the original behavior, but only for
fetch mirrors.

Handle input in Subversion's dumpfile format, version 3. This is the
format produced by "svnrdump dump" and "svnadmin dump --deltas", and
the main difference between v3 dumpfiles and the dumpfiles already
handled is that these can include nodes whose properties and text are
expressed relative to some other node.
To handle such nodes, we find which node the text and properties are
based on, handle its property changes, use the cat-blob command to
request the basis blob from the fast-import backend, use the
svndiff0_apply() helper to apply the text delta on the fly, writing
output to a temporary file, and then measure that postimage file's
length and write its content to the fast-import stream.
The temporary postimage file is shared between delta-using nodes to
avoid some file system overhead.
The svn-fe interface needs to be more complicated to accomodate the
backward flow of information from the fast-import backend to svn-fe.
The backflow fd is not needed when parsing streams without deltas,
though, so existing scripts using svn-fe on v2 dumps should
continue to work.

Setting that together with the update flag will check if the work tree
update would be successful without doing it for real.
The only class of problems that is not detected at the moment are file

The handle_options() function advances the base of the argument array and

wants to reallocate the argv array it passes to this function, and
attempts to do so by subtracting the returned value to compensate for the
change handle_options() makes to the new_argv.
But handle_options() did not correctly count when "-c <config=value>" is
given, causing a wrong pointer to be passed to realloc().
Fix it by saving the original argv at the beginning of handle_options(),

When switching away from a detached HEAD with "git checkout", we give a
listing of the commits about to be lost, and then tell how to resurrect
them since 8e2dc6a (commit: give final warning when reattaching HEAD to
leave commits behind, 2011-02-18).
This is a good safety measure for people who are not comfortable with the
detached HEAD state, but the advice on how to keep the state you just left
was given even to those who set advice.detachedHead to false.
Keep the warning and informational commit listing, but honor the setting
of advice.detachedHead to squelch the advice.

Somebody tried "git pull" from a random place completely outside the work
tree, while exporting GIT_DIR and GIT_WORK_TREE that are set to correct
places, e.g.
GIT_WORK_TREE=$HOME/git.git
GIT_DIR=$GIT_WORK_TREE/.git
export GIT_WORK_TREE GIT_DIR
cd /tmp
git pull
At the beginning of git-pull, we check "require-work-tree" and then
"cd-to-toplevel". I _think_ the original intention when I wrote the
command was "we MUST have a work tree, our $(cwd) might not be at the
top-level directory of it", and no stronger than that. That check is a
very sensible thing to do before doing cd-to-toplevel. We check that the
place we would want to go exists, and then go there.
But the implementation of require_work_tree we have today is quite
different. I don't have energy to dig the history, but currently it says:
test "$(git rev-parse --is-inside-work-tree 2>/dev/null)" = true ||
die "fatal: $0 cannot be used without a working tree."
Which is completely bogus. Even though we may happen to be just outside
of it right now, we may have a working tree that we can cd_to_toplevel
back to.
Add a function "require_work_tree_exists" that implements the check
this function originally intended (this is so that third-party scripts
that rely on the current behaviour do not have to get broken).
For now, update _no_ in-tree scripts, not even "git pull", as nobody on
the list seems to really care about the above corner case workflow that
triggered this. Scripts can be updated after vetting that they do want the
"we want to make sure the place we are going to go actually exists"
semantics.

Configure JavaScript-based ability to select common timezone for git
dates via %feature mechanism, namely 'javascript-timezone' feature.
The following settings are configurable:
* default timezone (defaults to 'local' i.e. browser timezone);
this also can function as a way to disable this ability,
by setting it to false-ish value (undef or '')
* name of cookie to store user's choice of timezone
* class name to mark dates
NOTE: This is a bit of abuse of %feature system, which can store only
sequence of values, rather than dictionary (hash); usually but not
always only a single value is used.

This will modify HTML, add CSS rules and add DOM event handlers so
that clicking on any date (the common part, not the localtime part)
will display a drop down menu to choose the timezone to change to.
Currently menu displays only the following timezones:
utc
local
-1200
-1100
...
+1100
+1200
+1300
+1400
In timezone selection menu each timezone is +1hr to the previous. The
code is capable of handling fractional timezones, but those have not
been added to the menu.
All changes are saved to a cookie, so page changes and closing /
reopening browser retains the last known timezone setting used.

This patch is based on Kevin Cernekee's <cernekee@gmail.com>
patch series entitled "gitweb: introduce localtime feature". While
Kevin's patch changed the server side output so that the timezone
was output from gitweb itself, this has a number of drawbacks, in
particular with respect to gitweb-caching.
This patch takes the same basic goal, display the appropriate times in
a given common timezone, and implements it in JavaScript. This
requires adding / using a new class, "datetime", to be able to find
elements to be adjusted from JavaScript. Appropriate dates are
wrapped in a span with this class.
Timezone to be used can be retrieved from "gitweb_tz" cookie, though
currently there is no way to set / manipulate this cookie from gitweb;
this is left for later commit.
Valid timezones, currently, are: "utc", "local" (which means that
timezone is taken from browser), and "+/-ZZZZ" numeric timezone as in
RFC-2822. Default timezone is "local" (currently not configurable,
left for later commit).
Fallback (should JavaScript not be enabled) is to treat dates as they
have been and display them, only, in UTC.
Pages affected:
* 'summary' view, "last change" field (commit time from latest change)
* 'log' view, author time
* 'commit' and 'commitdiff' views, author/committer time
* 'tag' view, tagger time

Split originally single gitweb.js file into smaller files, each
dealing with single issue / area of responsibility. This move should
make gitweb's JavaScript code easier to maintain.
For better webapp performance it is recommended[1][2][3] to combine
JavaScript files. Do it during build time (in gitweb/Makefile), by
straight concatenation of files into gitweb.js file (which is now
ignored as being generated). This means that there are no changes to
gitweb script itself - it still uses gitweb.js or gitweb.min.js, but
now generated.

When doing a combined diff, we did not respect textconv attributes at
all. This generally lead to us printing "Binary files differ" when we
could show a combined diff of the converted text.
This patch converts file contents according to textconv attributes. The
implementation is slightly ugly; because the textconv code is tightly
linked with the diff_filespec code, we temporarily create a diff_filespec
during conversion. In practice, though, this should not create a
performance problem.

This function actually does two things:
1. Load the userdiff driver for the filespec.
2. Decide whether the driver has a textconv component, and
initialize the textconv cache if applicable.
Only part (1) requires the filespec object, and some callers
may not have a filespec at all. So let's split them it into
two functions, and put part (2) with the userdiff code,
which is a better fit.

The combined diff code path is totally different from the
regular diff code path, and didn't handle binary files at
all. The results of a combined diff on a binary file could
range from annoying (since we spewed binary garbage,
possibly upsetting the user's terminal), to wrong (embedded
NULs caused us to show incorrect diffs, with lines truncated
at the NUL character), to potential security problems
(embedded NULs could interfere with "-z" output, possibly
defeating policy hooks which parse diff output).
Instead, we consider a combined diff to be binary if any of
the input blobs is binary. To show a binary combined diff,
we indicate "Binary blobs differ"; the "index" meta line
will show which parents had which blob.

A naive method of treating BEGIN/END blocks with a brace on the second
line as diff/grep funcname context involves also matching unrelated
lines that consist of all-caps letters:
sub foo {
print <<'EOF'
text goes here
...
EOF
... rest of foo ...
}
That's not so great, because it means that "git diff" and "git grep
--show-function" would write "=EOF" or "@@ EOF" as context instead of
a more useful reminder like "@@ sub foo {".
To avoid this, tighten the pattern to only match the special block
names that perl accepts (namely BEGIN, END, INIT, CHECK, UNITCHECK,
AUTOLOAD, and DESTROY). The list is taken from perl's toke.c.

The userdiff funcname mechanism has no concept of nested scopes ---
instead, "git diff" and "git grep --show-function" simply label the
diff header with the most recent matching line. Unfortunately that
means text following a subroutine in a POD section:
=head1 DESCRIPTION
You might use this facility like so:
sub example {
foo;
}
Now, having said that, let's say more about the facility.
Blah blah blah ... etc etc.
gets the subroutine name instead of the POD header in its diff/grep
funcname header, making it harder to get oriented when reading a
diff without enough context.
The fix is simple: anchor the funcname syntax to the left margin so
nested subroutines and packages like this won't get picked up. (The
builtin C++ funcname pattern already does the same thing.) This means
the userdiff driver will misparse the idiom
{
my $static;
sub foo {
... use $static ...
}
}
but I think that's worth it; we can revisit this later if the userdiff
mechanism learns to keep track of the beginning and end of nested
scopes.

some repetition.
Omit the space after >, <<, and < operators for consistency with
other scripts. Quote the <<here document delimiter and $ signs in
quotes so readers don't have to worry about the effect of shell
metacharacters.
Remove some unnecessary blank lines.
Run "git diff" as a separate command instead of as upstream of a pipe
that checks its output, so the exit status can be tested. In
particular, this way if "git diff" starts segfaulting the test harness
will notice.
Allow "error:" as a synonym for "fatal:" when checking error messages,
since whether a command uses die() or "return error()" is a small
implementation detail.

Introduce a "test_config" function to set a configuration variable
for use by a single test (automatically unsetting it when the
assertion finishes). If this function is used consistently, the
configuration used in a test_expect_success block can be read at the
beginning of that block instead of requiring reading all the tests
that come before. So it becomes a little easier to add new tests or
rearrange existing ones without fear of breaking configuration.
In particular, the test of alternation in xfuncname patterns also
checks that xfuncname takes precedence over funcname variable as a
sort of side-effect, since the latter leaks in from previous tests.
In the new syntax, the test has to say explicitly what variables it is
using, making the test clearer and a future regression in coverage
from carelessly editing the script less likely.

Most, but not all, tests in this script rely on attributes declaring
that files with a .java extension should use the "java" driver:
*.java diff=java
Split out a "set up" test to put such a .gitattributes in place after
the tests that do not want it have run, to make it more likely that
individual tests other than this setup test can be safely modified,
rearranged, or skipped. Presumably this setup code will learn to
request other drivers for other extensions in the same place when the
test suite learns to exercise other diff drivers.
Similarly, make sure that early test assertions that do not use these
default attributes set up .gitattributes appropriately for themselves,
so tests that run before can be modified with less risk of breaking

When the output to a path does not have to be converted, we can read from
the object database from the streaming API and write to the file in the
working tree, without having to hold everything in the memory.
The ident, auto- and safe- crlf conversions inherently require you to read
the whole thing before deciding what to do, so while it is technically
possible to support them by using a buffer of an unbound size or rewinding
and reading the stream twice, it is less practical than the traditional
"read the whole thing in core and convert" approach.
Adding streaming filters for the other conversions on top of this should
be doable by tweaking the can_bypass_conversion() function (it should be
renamed to can_filter_stream() when it happens). Then the streaming API
can be extended to wrap the git_istream streaming_write_entry() opens on
the underlying object in another git_istream that reads from it, filters
what is read, and let the streaming_write_entry() read the filtered
result. But that is outside the scope of this series.

that diff.suppress-blank-empty=true converts from " \n" to "\n".
Since it assumed there would always be a prefix character (the space),

As the band-aid to merge-recursive seems to regress complex merges in an
unpleasant way. The merge-recursive implementation needs to be rewritten
in such a way that it resolves renames and D/F conflicts entirely in-core
and not to touch working tree at all while doing so. But in the meantime,
this reverts commit ac9666f84 that merged the topic in its entirety.
When receiving a push, we advertise ref tips from any
alternate repositories, in case that helps the client send a
smaller pack. Since these refs don't actually exist in the
destination repository, we don't transmit the real ref
names, but instead use the pseudo-ref ".have".
If your alternate has a large number of duplicate refs (for
example, because it is aggregating objects from many related
repositories, some of which will have the same tags and
branch tips), then we will send each ".have $sha1" line
multiple times. This is a pointless waste of bandwidth, as
we are simply repeating the same fact to the client over and
over.
This patch eliminates duplicate .have refs early on. It does
so efficiently by sorting the complete list and skipping
duplicates. This has the side effect of re-ordering the
.have lines by ascending sha1; this isn't a problem, though,
as the original order was meaningless.
There is a similar .have system in fetch-pack, but it
does not suffer from the same problem. For each alternate
ref we consider in fetch-pack, we actually open the object
and mark it with the SEEN flag, so duplicates are
automatically culled.

The foreach_alt_odb function triggers a callback for each
alternate object db we have, with room for a single void
pointer as data. Currently, we always call refs_from_alternate_cb
as the callback function, and then pass another callback (to
receive each ref individually) as the void pointer.
This has two problems:
1. C technically forbids stuffing a function pointer into
a "void *". In practice, this probably doesn't matter
on any architectures git runs on, but it never hurts to
follow the letter of the law.
2. There is no room for an extra data pointer. Indeed, the
alternate_ref_fn that refs_from_alternate_cb calls
takes a void* for data, but we always pass it NULL.
Instead, let's properly stuff our function pointer into a
data struct, which also leaves room for an extra
caller-supplied data pointer. And to keep things simple for
existing callers, let's make a for_each_alternate_ref
function that takes care of creating the extra struct.

We add every local ref to a list so that we can mark them
and all of their ancestors back to a certain cutoff point.
However, if some refs point to the same commit, we will end
up adding them to the list many times.
Furthermore, since commit_lists are stored as linked lists,
we must do an O(n) traversal of the list in order to find
the right place to insert each commit. This makes building
the list O(n^2) in the number of refs.
For normal repositories, this isn't a big deal. We have a
few hundreds refs at most, and most of them are unique. But
consider an "alternates" repo that serves as an object
database for many other similar repos. For reachability, it
needs to keep a copy of the refs in each child repo. This
means it may have a large number of refs, many of which
point to the same commits.
By noting commits we have already added to the list, we can
shrink the size of "n" in such a repo to the number of
unique commits, which is on the order of what a normal repo
would contain (it's actually more than a normal repo, since child repos
may have branches at different states, but in practice it tends
to be much smaller than the list with duplicates).

as a single atomic event if everthing goes well.
Even though the old code insisted that "git notes rm" must be given only

condition was not tested. Add tests to handle the new case where we feed
multiple objects, and also make sure if there is a bad input, no change

dangerous: git-add--interactive.perl will ignore the ^[ and [

As a band-aid fix, use Term::Cap to get all terminal capabilities.
Then use the heuristic that any capability value that starts with ^[
(i.e., \e in perl) must be a key input sequence. Finally, given an
input that starts with ^[, read more characters until we have read a
full escape sequence, then return that to the caller. We use a
timeout of 0.5 seconds on the subsequent reads to avoid getting stuck
if the user actually input a lone ^[.

Commit 09c9957c fixes a deadlock in which pack-objects
fails, the remote end is still waiting for pack data, and we
are still waiting for the remote end to say something (see
that commit for a much more in-depth explanation).
We solved the problem there by making sure the output pipe
is closed on error; thus the remote sees EOF, and proceeds
to complain and close its end of the connection.
However, in the special case of push over git://, we don't
have a pipe, but rather a full-duplex socket, with another
dup()-ed descriptor in place of the second half of the pipe.
In this case, closing the second descriptor signals nothing
to the remote end, and we still deadlock.
This patch calls shutdown() explicitly to signal EOF to the
other side.

They might care because they want to do a half-duplex close.
With pipes, that means simply closing the output descriptor;

The git_connect function returns two ends of a pipe for
talking with a remote, plus a struct child_process
representing the other end of the pipe. If we have a direct
socket connection, then this points to a special "no_fork"
child process.
The code path for doing git-over-pipes or git-over-ssh sets
up this child process to point to the child git command or
the ssh process. When we call finish_connect eventually, we
check wait() on the command and report its return value.
The code path for git://, on the other hand, always sets it
to no_fork. In the case of a direct TCP connection, this
makes sense; we have no child process. But in the case of a
proxy command (configured by core.gitproxy), we do have a
child process, but we throw away its pid, and therefore
ignore its return code.
Instead, let's keep that information in the proxy case, and
respect its return code, which can help catch some errors
(though depending on your proxy command, it will be errors
reported by the proxy command itself, and not propagated
from git commands. Still, it is probably better to propagate
such errors than to ignore them).
It also means that the child_process field can reliably be
used to determine whether the returned descriptors are
actually a full-duplex socket, which means we should be
using shutdown() instead of a simple close.

The way "object replacement" mechanism was tucked to the read_sha1_file()
interface was suboptimal in a couple of ways:
- Callers that want it to die with useful diagnosis upon seeing a corrupt
object does not have a way to say that they do not want any object
replacement.
- Callers who do not want it to die but want to handle the errors
themselves are told to arrange to call read_object(), but the function
does not use the replacement mechanism, and also it is a file scope
static function that not many callers can call to begin with.
This adds a read_sha1_file_extended() that takes a set of flags; the
callers of read_sha1_file() passes a flag READ_SHA1_FILE_REPLACE to ask
for object replacement mechanism to kick in.
Later, we could add another flag bit to tell the function to return an
error instead of dying and then remove the misguided "call read_object()
yourself".

In a repository without object replacement, lookup_replace_object() should
be a no-op. Check the flag "read_replace_refs" on the side of the caller,
and bypess a function call when we know we are not dealing with replacement.
Also, even when we are set up to replace objects, if we do not find any
replacement defined, flip that flag off to avoid function call overhead
for all the later object accesses.
As this change the semantics of the flag from "do we need read the
replacement definition?" to "do we need to check with the lookup table?"
the flag needs to be renamed later to something saner, e.g. "use_replace",
when the codebase is calmer, but not now.

Change the "pot" target to also extract strings from our $(SCRIPT_SH)
files with xgettext(1).
Note that due to Jonathan Nieder's trick of doing "mv $@+ $@" at the
end of the target the "pot" target will now warn:
$ make pot
XGETTEXT po/git.pot
po/git.pot+: warning: Charset "CHARSET" is not a portable encoding name.
Message conversion to user's charset might not work.
This warnings is emitted because xgettext is writing into a non-*.pot
file, it's harmless however. The content that's written out is
equivalent to what it would be if we were writing directly into an
existing POT file with --join-existing.
As part of this change I've eliminated the && chain between xgettext
calls, this is incompatible with $(QUIET_XGETTEXT), if the && is left
in it'll emit:
/bin/sh: @echo: not found
Since it's redundant (the Makefile will stop if there's an error) I've
removed it altogether.

Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g

Commands like "git status", "git diff" and "git fetch" would fail when the
.gitmodules file contained merge conflicts because the config parser would
call die() when hitting the conflict markers:
"fatal: bad config file line <n> in <path>/.gitmodules"
While this behavior was on the safe side, it is really unhelpful to the
user to have commands like status and diff fail, as these are needed to
find out what's going on. And the error message is only mildly helpful,
as it points to the right file but doesn't mention that it is unmerged.
Users of git gui were not shown any conflicts at all when this happened.
Improve the situation by checking if the index records .gitmodules as
unmerged. When that is the case we can't make any assumptions about the
configuration to be found there after the merge conflict is resolved by
the user, so assume that all recursion is disabled unless .git/config or
the global config say otherwise.
As soon as the merge conflict is resolved and the .gitmodules file has
been staged subsequent commands again honor any configuration done there.

When adding a new content to the repository, we have always slurped
the blob in its entirety in-core first, and computed the object name
and compressed it into a loose object file. Handling large binary
files (e.g. video and audio asset for games) has been problematic
because of this design.
At the middle level of "git add" callchain is an internal API
index_fd() that takes an open file descriptor to read from the
working tree file being added with its size. Teach it to call out to
fast-import when adding a large blob.
The write-out codepath in entry.c::write_entry() should be taught to
stream, instead of reading everything in core. This should not be so
hard to implement, especially if we limit ourselves only to loose
object files and non-delta representation in packfiles.

The zsh support of git-completion script in contrib/ is broken for current
versions of zsh, and does not notice when there's a subcommand.
For example: "git log origi<TAB>" gives no completions because it would
try to find a "git origi..." command. This will be fixed by zsh 4.3.12,
but for now we can workaround it by backporting the same fix as zsh folks
implemented.
The problem started after commit v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4), which introduced
_get_comp_words_by_ref() that comes from bash-completion[1] scripts, and
relies on the 'words' variable.
However, it turns out 'words' is a special variable used by zsh
completion. From zshcompwid(1):
[...] the parameters are reset on each function exit (including nested
function calls from within the completion widget) to the values they had
when the function was entered.
As a result, subcommand words are lost. Ouch.
This is now fixed in the latest master branch of zsh[2] by simply defining
'words' as hidden (typeset -h), which removes the special meaning inside
the emulated bash function. So let's do the same.
Jonathan Nieder helped on the commit message.

such a string in the log message (hence "it cannot be a ref"), and after
seeing that :/no-such-string-ever-existed is not a filename (hence "it
cannot be a path, either"), another time to give "better diagnosis".
The thing is, the second time it runs, we already know that traversing the
history all the way down to the root will _not_ find any matching commit.
Rename misguided "gently" parameter, which is turned off _only_ when the
"detailed diagnosis" codepath knows that it cannot be a ref and making the
call only for the caller to die with a message. Flip its meaning (and
adjust the callers) and call it "only_to_die", which is not a great name,

This reverts commit d0546e2d48, which
was only meant to be a Proof-of-concept used during the discussion.
The real implementation of the feature needs to wait until we migrate
all the code to use "struct pathspec", not "char **", to represent
richer semantics given to pathspec.
Sparse-setting code follows closely how files are excluded in
read_directory(), every entry (including directories) are fed to
excluded_from_list() to decide if the entry is suitable. Directories
are treated no different than files. If a directory is matched (or
not), the whole directory is considered matched (or not) and the
process moves on.
This generally works as long as there are no patterns to exclude parts
of the directory. In case of sparse checkout code, the following patterns
t
!t/t0000-basic.sh
will produce a worktree with full directory "t" even if t0000-basic.sh
is requested to stay out.
By the same reasoning, if a directory is to be excluded, any rules to
re-include certain files within that directory will be ignored.
Fix it by always checking files against patterns. If no pattern can be
used to decide whether an entry is in our out
(ie. excluded_from_list() returns -1), the entry will be
included/excluded the same as their parent directory.

Notice that the prefix specified for the build influenced the definitions

Kacper Kornet noticed that this was furthermore only the case when the
build was triggered using 'make prefix=/usr', i.e., the prefix was given

config.mak because this file is included much later in the Makefile.
To fix this, move the conditional after the inclusion of config.mak.
Additionally, it is desirable to specify the etc directory for a build
(for example, a build with prefix /usr/local may still want to have the
system configuration in /etc/gitconfig). For this purpose, promote the
variable 'sysconfdir' from a helper variable to a configuration
variable. The prefix check that was moved must now be wrapped so that it
does not override sysconfdir setting given in config.mak.

Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh. Modern POSIX compliant shells (e.g. dash,

says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group. We can avoid this issue and future-proof the

Since c0cb4ed (git-instaweb: Configure it to work with new gitweb
structure, 2010-05-28) git-instaweb does not re-create gitweb.cgi
etc., but makes use of installed gitweb. Therefore simplify
git-instaweb dependency on gitweb subsystem in main Makefile from
'gitweb/gitweb.cgi gitweb/static/gitweb.css gitweb/static/gitweb.js'
to simply 'gitweb'.
This is preparation for splitting gitweb.perl script, and for
splitting gitweb.js (to be reassembled / combined on build). This way
we don't have to duplicate parts of gitweb/Makefile in main
Makefile... it is also more correct description of git-instaweb
dependency.

Maybe some day in the future we will want to support a syntax
like
[merge]
ff = branch1
ff = branch2
ff = branch3
in addition to the currently permitted "true", "false", and "only"
values. So make sure we continue to treat such configurations as
though an unknown variable had been defined rather than erroring out,
until it is time to implement such a thing, so configuration files
using such a facility can be shared between present and future git.
While at it, add a few missing && and start the "combining --squash
and --no-ff" test with a known state so we can be sure it does not
succeed or fail for the wrong reason.

Currently verify_parents only makes sure that the earlier parents of

example, parent reduction works correctly when making an octopus.
Fix it by checking that HEAD^(n+1) is not a valid commit name.

The parsing of the additional command line parameters supplied to
the branch.<name>.mergeoptions configuration variable was implemented
at the wrong stage. If any merge-related variable came after we read
branch.<name>.mergeoptions, the earlier value was overwritten.
We should first read all the merge.* configuration, override them by
reading from branch.<name>.mergeoptions and then finally read from
the command line.
This patch should fix it, even though I now strongly suspect that
branch.<name>.mergeoptions that gives a single command line that
needs to be parsed was likely to be an ill-conceived idea to begin
with. Sigh...

Most of git's tests write files and define shell functions and
variables that will last throughout a test script at the top of
the script, before all test assertions:
. ./test-lib.sh
VAR='some value'
export VAR
>empty
fn () {
do something
}
test_expect_success 'setup' '
... nontrivial commands go here ...
'
Two scripts use a different style with this kind of trivial code
enclosed by a test assertion; fix them. The usual style is easier to
read since there is less indentation to keep track of and no need to
worry about nested quotes; and on the other hand, because the commands
in question are trivial, it should not make the test suite any worse
at catching future bugs in git.
While at it, make some other small tweaks:
- spell function definitions with a space before () for consistency
with other scripts;
- use the self-contained command "git mktree </dev/null" in
preference to "git write-tree" which looks at the index when
writing an empty tree.

Commit 09c9957 (send-pack: avoid deadlock when pack-object
dies early, 2011-04-25) attempted to fix a hang in the
stateless rpc case by closing a file descriptor early, but
we still need that descriptor.
Basically the deadlock can happen when pack-objects fails,
and the descriptor to upstream is left open. We never send
the pack, so the upstream is left waiting for us to say
something, and we are left waiting for upstream to close the
connection.
In the non-rpc case, our descriptor points straight to the
upstream. We hand it off to run-command, which takes
ownership and closes the descriptor after pack-objects
finishes (whether it succeeds or not).
Commit 09c9957 tried to emulate that in the rpc case. That
isn't right, though. We actually have a descriptor going
back to the remote-helper, and we need to keep using it
after pack-objects is finished. Closing it early completely
breaks pushing via smart-http.
We still need to do something on error to signal the
remote-helper that we won't be sending any pack data
(otherwise we get the deadlock). In an ideal world, we
would send a special packet back that says "Sorry, there was
an error". But the remote-helper doesn't understand any such
packet, so the best we can do is close the descriptor and
let it report that we hung up unexpectedly.

Modify the p4merge client command to pass a reference to an empty file
instead of the local file when no base revision available.
In the situation where a merge tries to add a file from one branch
into a branch that already contains that file (by name), p4merge
currently seems to have successfully automatically resolved the
'conflict' when it is opened (correctly if the files differed by
just whitespace for example) but leaves the save button disabled. This
means the user of the p4merge client cannot commit the resolved
changes back to disk and merely exits, leaving the original
(merge-conflicted) file intact on the disk.
Provide an empty base file to p4merge so that it leaves the save
button enabled. This will allow saving of the auto-resolution to

The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.
For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.
This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!
This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.
While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

There were no tests for either, except a brief use in

These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.
For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.
This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.
Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects. Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.
Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed). Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.
Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.
The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results). If 'ctags' feature is disabled, then searching by tag is
too.
The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.
Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.
While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.

This adds the $projects_list_group_categories option which, if enabled,
will result in grouping projects by category on the project list page.
The category is specified for each project by the $GIT_DIR/category file
or the 'gitweb.category' variable in its configuration file. By default,
projects are put in the $project_list_default_category category.
Note:
- Categories are always sorted alphabetically, with projects in
each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
category headers are only displayed for projects present on the page.
The feature is inspired from Sham Chukoury's patch for the XMMS2

for categories is inspired from Gustavo Sverzut Barbieri's patch to
group projects by path.

The major change is removing the ability to edit content tags (ctags)
in a web browser.
The interface was created by gitweb, while actual editing of tags was
to be done by external script; the API was not defined, and neither
was provided example implementation. Such split is also a bit fragile
- interface and implementation have to be kept in sync. Gitweb
provided only ability to add tags; you could not edit tags nor delete
them.
Format of ctags is now described in the comment above git_get_project_ctags
subroutine. Gitweb now is more robust with respect to original ctags
format; it also accepts two new formats: $GIT_DIR/ctags file, with one
content tag per line, and multi-value `gitweb.ctag' config variable.
Gathering all ctags of all project is now put in git_gather_all_ctags
subroutine, making git_project_list_body more clear.
git_populate_project_tagcloud subroutine now generates data used for
tag cloud, including generation of ctag link, also in the case
HTML::TagCloud module is unavailable. Links are now generated using
href() subroutine - this is more robust, as ctags might contain '?',
';' and '=' special characters that need to be escaped in query param.
Shown tags are HTML-escaped.
The generation of tag cloud in git_show_project_tagcloud in the case
when HTML::TagCloud is not available is now changed slightly.
The 'content tags' field on project summary page is made more in line
with other fields in "projects_list" table. Because one cannot now
add new tags from web interface, this field is no longer displayed
when there are no content tags for given project.

When encountering errors or unknown tokens while parsing parameters to the
--dirstat option, it makes sense to die() with an error message informing
the user of which parameter did not make sense. However, when parsing the
diff.dirstat config variable, we cannot simply die(), but should instead
(after warning the user) ignore the erroneous or unrecognized parameter.
After all, future Git versions might add more dirstat parameters, and
using two different Git versions on the same repo should not cripple the
older Git version just because of a parameter that is only understood by
a more recent Git version.
This patch fixes the issue by refactoring the dirstat parameter parsing
so that parse_dirstat_params() keeps on parsing parameters, even if an
earlier parameter was not recognized. When parsing has finished, it returns
zero if all parameters were successfully parsed, and non-zero if one or
more parameters were not recognized (with appropriate error messages
appended to the 'errmsg' argument).
The parse_dirstat_params() callers then decide (based on the return value
from parse_dirstat_params()) whether to warn and ignore (in case of
diff.dirstat), or to warn and die (in case of --dirstat).
The patch also adds a couple of tests verifying the correct behavior of
--dirstat and diff.dirstat in the face of unknown (possibly future) dirstat
parameters.

This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.
The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).
For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.
In linux-2.6.git, running the three different --dirstat modes:
time git diff v2.6.20..v2.6.30 --dirstat=changes > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=lines > /dev/null
vs.
time git diff v2.6.20..v2.6.30 --dirstat=files > /dev/null
yields the following average runtimes on my machine:
- "changes" (default): ~6.0 s
- "lines": ~9.6 s
- "files": ~0.1 s
So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.
The patch also includes documentation and tests for the new dirstat mode.

The config is obviously overridden by --dirstat arguments passed on the

Instead of having multiple interconnected dirstat-related options, teach
the --dirstat option itself to accept all behavior modifiers as parameters.
- Preserve the current --dirstat=<limit> (where <limit> is an integer
specifying a cut-off percentage)
- Add --dirstat=cumulative, replacing --cumulative
- Add --dirstat=files, replacing --dirstat-by-file
- Also add --dirstat=changes and --dirstat=noncumulative for specifying the
current default behavior. These allow the user to reset other --dirstat
parameters (e.g. 'cumulative' and 'files') occuring earlier on the
command line.
The deprecated options (--cumulative and --dirstat-by-file) are still
functional, although they have been removed from the documentation.
Allow multiple parameters to be separated by commas, e.g.:
--dirstat=files,10,cumulative
Update the documentation accordingly, and add testcases verifying the
behavior of the new syntax.

The expected output from --dirstat=0, is to include any directory with
changes, even if those changes contribute a minuscule portion of the total
changes. However, currently, directories that contribute less than 0.1% are
not included, since their 'permille' value is 0, and there is an
'if (permille)' check in gather_dirstat() that causes them to be ignored.
This test is obviously intended to exclude directories that contribute no
changes whatsoever, but in this case, it hits too broadly. The correct
check is against 'this_dir' from which the permille is calculated. Only if
this value is 0 does the directory truly contribute no changes, and should
be skipped from the output.
This patches fixes this issue, and updates corresponding testcases to
expect the new behvaior.

Currently, t4013 is the only selftest that exercises the --dirstat machinery,
but it only does a superficial verification of --dirstat's output.
This patch adds a new selftest - t4047-diff-dirstat.sh - which prepares a
commit containing:
- unchanged files, changed files and files with rearranged lines
- copied files, moved files, and unmoved files
It then verifies the correct dirstat output for that commit in the following
dirstat modes:
- --dirstat
- -X
- --dirstat=0
- -X0
- --cumulative
- --dirstat-by-file
- (plus combinations of the above)
Each of the above tests are also run with:
- no rename detection
- rename detection (-M)
- expensive copy detection (-C -C)

The names and e-mails are sanitized by fmt_ident() when creating commits,
so that they do not contain "<" nor ">", and the "committer" and "author"
lines in the commit object will always be in the form:
("author" | "committer") name SP "<" email ">" SP timestamp SP zone
When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".
We should instead look for SP followed by "<", to match the logic of the
side that formats these lines.

'git rebase' uses 'git merge' to preserve merges (-p). This preserves
the original merge commit correctly, except when the original merge
commit was created by 'git merge --no-ff'. In this case, 'git rebase'
will fail to preserve the merge, because during 'git rebase', 'git
merge' will simply fast-forward and skip the commit. For example:
B
/ \
A---M
/
---o---O---P---Q
If we try to rebase M onto P, we lose the merge commit and this happens:
A---B
/
---o---O---P---Q
To correct this, we simply do a "no fast-forward" on all merge commits
when rebasing. Since by the time we decided to do a 'git merge' inside
'git rebase', it means there was a merge originally, so 'git merge'
should always create a merge commit regardless of what the merge
branches look like. This way, when rebase M onto P from the above
example, we get:
B
/ \
A---M
/
---o---O---P---Q

The "_get_comp_words_by_ref -n := words" command from the
bash_completion library reassembles a modified version of COMP_WORDS
with ':' and '=' no longer treated as word separators and stores it in
the ${words[@]} array. Git's programmable tab completion script uses
this to abstract away the difference between bash v3's and bash v4's
definitions of COMP_WORDS (bash v3 used shell words, while bash v4
breaks at separator characters); see v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4, 2010-12-02).
zsh has (or rather its completion functions have) another idea about
what ${words[@]} should contain: the array is prepopulated with the
words from the command it is completing. For reasons that are not
well understood, when git-completion.bash reserves its own "words"
variable with "local words", the variable becomes empty and cannot be
changed from then on. So the completion script neglects the arguments
it has seen, and words complete like git subcommand names. For
example, typing "git log origi<TAB>" gives no completions because
there are no "git origi..." commands.
However, when this words variable is not declared as local but is just
populated by _get_comp_words_by_ref() and then read in various
completion functions, then zsh seems to be happy about it and our
completion script works as expected.
So, to get our completion script working again under zsh and to
prevent the words variable from leaking into the shell environment
under bash, we will only declare words as local when using bash.

In v1.7.4-rc0~11^2~2 (bash: get --pretty=m<tab> completion to work
with bash v4, 2010-12-02) we started to use _get_comp_words_by_ref()
to access completion-related variables. That was large change, and to
make it easily reviewable, we invoked _get_comp_words_by_ref() in each
completion function and systematically replaced every occurance of
bash's completion-related variables ($COMP_WORDS and $COMP_CWORD) with
variables set by _get_comp_words_by_ref().
This has the downside that _get_comp_words_by_ref() is invoked several
times during a single completion. The worst offender is perhaps 'git
log mas<TAB>': during the completion of 'master'
_get_comp_words_by_ref() is invoked no less than six times.
However, the variables $prev, $cword, and $words provided by
_get_comp_words_by_ref() are not modified in any of the completion
functions, and the previous commit ensures that the $cur variable is
not modified as well. This makes it possible to invoke
_get_comp_words_by_ref() to get those variables only once in our
toplevel completion functions _git() and _gitk(), and all other
completion functions will inherit them.

completion-related variables, and the $cur variable holds the word
containing the current cursor position in all completion functions.
This $cur variable is left unchanged in most completion functions;
there are only four functions modifying its value, namely __gitcomp(),
__git_complete_revlist_file(), __git_complete_remote_or_refspec(), and
_git_config().
If this variable were never modified, then it would allow us a nice
optimisation and cleanup. Therefore, this patch assigns $cur to an
other local variable and uses that for later modifications in those
four functions.

Commit a8f3e2219 introduced the strbuf_grow() call to strbuf_setlen() to
make ensure that there was at least one byte available to write the
mandatory trailing NUL, even for previously unallocated strbufs.
Then b315c5c0 added strbuf_slopbuf for the same reason, only globally for
all uses of strbufs.
Thus the strbuf_grow() call can be removed now. This avoids readers of
strbuf.h from mistakenly thinking that strbuf_setlen() can be used to
extend a strbuf.
The following assert() needs to be changed to cope with the fact that
sb->alloc can now be zero, which is OK as long as len is also zero. As
suggested by Junio, use the chance to convert it to a die() with a short
explanatory message. The pattern of 'die("BUG: ...")' is already used in
strbuf.c.
This was the only assert() in strbuf.[ch], so assert.h doesn't have to be
included anymore either.

If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.
In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:
From: Foo B. Bar <author@example.com>
without quotes, and properly quote the "." when they send
the actual mail. Others may not, or may screw up harder
things like:
From: Foo "The Baz" Bar <author@example.com>
For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.
So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all

For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files. Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.
Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems. In particular, OpenBSD does not appear to
support it.
Supply '-n' to gzip to exclude timestamp from output and produce idential

* js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix:
send-pack: avoid deadlock when pack-object dies early
Evil merge to adjust the way the use of pthreads in sideband-demultiplexor
was decided (earlier it was "if we are not on Windows", now it is "if we
are not using pthreads").
Send-pack deadlocks in two ways when pack-object dies early (for example,
because there is some repo corruption).
The first deadlock happens with the smart push protocol (--stateless-rpc).
After the initial rev-exchange, the remote is waiting for the pack data
to arrive, and the sideband demuxer at the local side continues trying to
stream data from the remote repository until it gets EOF. Meanwhile,
send-pack (in function pack_objects()) has noticed that pack-objects did
not produce output and died. Back in send_pack(), it now tries to clean
up the sideband demuxer using finish_async(). The demuxer, however, waits
for the remote end to close down, the remote waits for pack data, and
the reason that it still waits is that send-pack forgot to close the
outgoing channel. Add the missing close() in pack_objects().
The second deadlock happens in a similar constellation when the sideband
demuxer runs in a forked process (rather than in a thread). Again, the
remote end waits for pack data to arrive, the sideband demuxer waits for
the remote to shut down, and send-pack (in the regular clean-up) waits for
the demuxer to terminate. This time, the send-pack parent process closes
the writable end of the outgoing channel (in start_command() that spawned
pack-objects) so that after the death of the pack-objects process all
writable ends should have been closed and the remote repo should see EOF.
This does not happen, however, because when the sideband demuxer was forked
earlier, it also inherited a writable end; it remains open and keeps the
remote repo from seeing EOF. To break this deadlock, close the writable end
in the demuxer.

"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.
It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.
As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.
Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.
The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

In order to fix the problem, we define a new sparse target which
depends on a set of non-existent "sparse object" files (*.sp)
which correspond to the set of C source files. In addition to the
new target, we also provide a new pattern rule for "creating" the
sparse object files from the source files by running cgcc. This
allows us to add '*.sp' to the rules setting the target-specific
EXTRA_CPPFLAGS variable, which is then included in the new pattern
rule to run cgcc.
Also, we change the 'check' target to re-direct the user to the
new sparse target.

As v1.6.0-rc2~42 (Allow "non-option" revision options in
parse_option-enabled commands, 2008-07-31) explains, options handled
by setup_revisions fall into two categories:
1. global options like --topo-order handled by parse_revision_opt,
which can take detached arguments and can be parsed in advance;
2. pseudo-options that must be parsed in order with their revision
counterparts, like --not and --all.
The global options are taken care of by handle_revision_opt; the
pseudo-options are currently in a deeply indented portion of
setup_revisions. Give them their own function for easier reading.
The only goal is to make setup_revisions easier to read straight
through. No functional change intended.

When relative dates are more than about a year ago, we start
writing them as "Y years, M months". At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:
Y = days / 365
M = (days % 365 + 15) / 30
This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").
We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".
Implement this differently with months of size
onemonth = 365/12
so that
totalmonths = (long)( (days + onemonth/2)/onemonth )
years = totalmonths / 12
months = totalmonths % 12
In order to do this without floats, we write the first formula as
totalmonths = (days*12*2 + 365) / (365*2)

If start_command fails after forking and before exec finishes, there
is not much use in noticing an I/O error on top of that.
finish_command will notice that the child exited with nonzero status
anyway. So as noted in v1.7.0.3~20^2 (run-command.c: fix build
warnings on Ubuntu, 2010-01-30) and v1.7.5-rc0~29^2 (2011-03-16), it
is safe to ignore errors from write in this codepath.
Even so, the result from write contains useful information: it tells
us if the write was cancelled by a signal (EINTR) or was only
partially completed (e.g., when writing to an almost-full pipe).
Let's use write_in_full to loop until the desired number of bytes have
been written (still ignoring errors if that fails).
As a happy side effect, the assignment to a dummy variable to appease
gcc -D_FORTIFY_SOURCE is no longer needed. xwrite and write_in_full
check the return value from write(2).
Noticed with gcc -Wunused-but-set-variable.

fixed it, the run_command facility would write a truncated error
message when the command is present but cannot be executed for some
other reason. For example, if I add a 'hello' command to git:
$ echo 'echo hello' >git-hello
$ chmod +x git-hello
$ PATH=.:$PATH git hello
hello
and make it non-executable, this is what I normally get:
$ chmod -x git-hello
$ git hello
fatal: cannot exec 'git-hello': Permission denied
But with the problematic versions, we get disturbing output:
$ PATH=.:$PATH git hello
fatal: $
Add some tests to make sure it doesn't happen again.
The hello-script used in these tests uses cat instead of echo because
on Windows the bash spawned by git converts LF to CRLF in text written
by echo while the bash running tests does not, causing the test to
fail if "echo" is used. Thanks to Hannes for noticing.

Add a DISCUSSION section to the "git format-patch" manual to encourage
people to send patches in a form that can be applied by "git am"

1. The default form in which most metadata goes in the mail header
and the message body starts with the patch description;
2. The snipsnip form in which a message starts with pertinent

The example requires QP encoding in the "Subject:" header intended for

being startled by it later. By contrast, in-body "From:" and

We already wrap names in "from" headers, which tend to be
the long part of an address. But it's also possible for a
long name to not be wrapped, but to make us want to wrap the
email address. For example (imagine for the sake of
readability we want to wrap at 50 characters instead of 78):
From: this is my really long git name <foo@example.com>
The name does not overflow the line, but the name and email
together do. So we would rather see:
From: this is my really long git name
<git@example.com>
Because we wrap the name separately during add_rfc2047, we
neglected this case. Instead, we should see how long the
final line of the wrapped name ended up, and decide whether
or not to wrap based on that. We can't break the address
into multiple parts, so we either leave it with the name, or
put it by itself on a line.

rearranged, because the "damage" calculated by show_dirstat() is 0.
However, if the object name has changed, we already know that there is
some damage, and it is unintuitive to claim there is _no_ damage.
Teach show_dirstat() to assign a minimum amount of damage (== 1) to
entries for which the analysis otherwise yields zero damage, to still
represent that these files are changed, instead of saying that there
is no change.

Currently, when using --dirstat-by-file, it first does the full --dirstat
analysis (using diffcore_count_changes()), and then resets 'damage' to 1,
if any damage was found by diffcore_count_changes().
But --dirstat-by-file is not interested in the file damage per se. It only
cares if the file changed at all. In that sense it only cares if the blob
object for a file has changed. We therefore only need to compare the
object names of each file pair in the diff queue and we can skip the
entire --dirstat analysis and simply set 'damage' to 1 for each entry
where the object name has changed.
This makes --dirstat-by-file faster, and also bypasses --dirstat's practice
of ignoring rearranged lines within a file.
The patch also contains an added testcase verifying that --dirstat-by-file
now detects changes that only rearrange lines within a file.

The earlier design was to take whatever non-alnum that the short format
parser happens to support, leaving the rest as part of the pattern, so a
version of git that knows '*' magic and a version that does not would have
behaved differently when given ":*Makefile". The former would have
applied the '*' magic to the pattern "Makefile", while the latter would
used no magic to the pattern "*Makefile".
Instead, just reserve all non-alnum ASCII letters that are neither glob
nor regexp special as potential magic signature, and when we see a magic
that is not supported, die with an error message, just like the longhand
codepath does.
With this, ":%#!*Makefile" will always mean "%#!" magic applied to the
pattern "*Makefile", no matter what version of git is used (it is a
different matter if the version of git supports all of these three magic
matching rules).
Also make ':' without anything else to mean "there is no pathspec". This
would allow differences between "git log" and "git log ." run from the top
level of the working tree (the latter simplifies no-op commits away from
the history) to be expressed from a subdirectory by saying "git log :".

Support ":/" magic string that can be prefixed to a pathspec element to
say "this names the path from the top-level of the working tree", when
you are in the subdirectory.
For example, you should be able to say:
$ edit Makefile ;# top-level
$ cd Documentation
$ edit git.txt ;# in the subdirectory
and then do one of three things, still inside the subdirectory:
$ git add -u . ;# add only Documentation/git.txt
$ git add -u :/ ;# add everything, including paths outside Documentation
$ git add -u ;# whatever the default setting is.
To truly support magic pathspec, the API needs to be restructured so that
get_pathspec() and init_pathspec() are unified into one call. Currently,
the former just prefixes the user supplied pathspec with the current
subdirectory path, and the latter takes the output from the former and
pre-parses them into a bit richer structure for easier handling. They
should become a single API function that takes the current subdirectory
path and the remainder of argv[] (after parsing --options and revision
arguments from the command line) and returns an array of parsed pathspec
elements, and "magic" should become attributes of struct pathspec_item.
This patch implements only "top" magic because it can be hacked into the
system without such a refactoring.
The syntax for magic pathspec prefix is designed to be extensible yet
simple to type to invoke a simple magic like "from the top". The parser
for the magic prefix is hooked into get_pathspec() function in this patch,
and it needs to be moved when we refactor the API.
But we have to start from somewhere.

In a pthread-enabled version of upload-pack, there's a race condition
that can cause a deadlock on the fflush(NULL) we call from run-command.
What happens is this:
1. Upload-pack is informed we are doing a shallow clone.
2. We call start_async() to spawn a thread that will generate rev-list
results to feed to pack-objects. It gets a file descriptor to a
pipe which will eventually hook to pack-objects.
3. The rev-list thread uses fdopen to create a new output stream
around the fd we gave it, called pack_pipe.
4. The thread writes results to pack_pipe. Outside of our control,
libc is doing locking on the stream. We keep writing until the OS
pipe buffer is full, and then we block in write(), still holding
the lock.
5. The main thread now uses start_command to spawn pack-objects.
Before forking, it calls fflush(NULL) to flush every stdio output
buffer. It blocks trying to get the lock on pack_pipe.
And we have a deadlock. The thread will block until somebody starts
reading from the pipe. But nobody will read from the pipe until we
finish flushing to the pipe.
To fix this, we swap the start order: we start the
pack-objects reader first, and then the rev-list writer
after. Thus the problematic fflush(NULL) happens before we
even open the new file descriptor (and even if it didn't,
flushing should no longer block, as the reader at the end of
the pipe is now active).

Before we apply a stash, we make sure there are no changes
in the worktree that are not in the index. This check dates
back to the original git-stash.sh, and is presumably
intended to prevent changes in the working tree from being
accidentally lost during the merge.
However, this check has two problems:
1. It is overly restrictive. If my stash changes only file
"foo", but "bar" is dirty in the working tree, it will
prevent us from applying the stash.
2. It is redundant. We don't touch the working tree at all
until we actually call merge-recursive. But it has its
own (much more accurate) checks to avoid losing working
tree data, and will abort the merge with a nicer
message telling us which paths were problems.
So we can simply drop the check entirely.

Once upon a time, "git rev-parse ref@{9999999}" did not
generate an error. Therefore when we got an invalid stash
reference in "stash apply", we could end up not noticing
until quite late. Commit b0f0ecd (detached-stash: work
around git rev-parse failure to detect bad log refs,
2010-08-21) handled this by checking for the "Log for stash
has only %d entries" warning on stderr when we validated the
ref.
A few days later, e6eedc3 (rev-parse: exit with non-zero
status if ref@{n} is not valid., 2010-08-24) fixed the
original issue. That made the extra stderr test superfluous,
but also introduced a new bug. Now the early call to:
git rev-parse --symbolic "$@"
fails, but we don't notice the exit code. Worse, its empty
output means we think the user didn't provide us a ref, and
we try to apply stash@{0}.
This patch checks the rev-parse exit code and fails early in
the revision parsing process. We can also get rid of the
stderr test; as a bonus, this means that "stash apply" can
now run under GIT_TRACE=1 properly.

Starting with commit c793430 (Limit file descriptors used by packs,
2011-02-28), git uses getrlimit to tell how many file descriptors it
can use. Unfortunately it does not include the header declaring that
function, resulting in compilation errors:
sha1_file.c: In function 'open_packed_git_1':
sha1_file.c:718: error: storage size of 'lim' isn't known
sha1_file.c:721: warning: implicit declaration of function 'getrlimit'
sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function)
sha1_file.c:718: warning: unused variable 'lim'
The standard header to include for this is <sys/resource.h> (which on
some systems itself requires declarations from <sys/types.h> or
<sys/time.h>). Probably the problem was missed until now because in
current glibc sys/resource.h happens to be included by sys/wait.h.
MinGW does not provide sys/resource.h (and compat/mingw takes care of
providing getrlimit some other way), so add the missing #include to
the "#ifndef __MINGW32__" block in git-compat-util.h.

for deleted files. When used with -B (represent total rewrite as a single
wholesale deletion followed by a single wholesale addition), the preimage
text is also omitted.
To prevent such a patch from being applied by mistake, the output is
designed not to be usable by "git apply" (or GNU "patch"); it is strictly
for human consumption.
It of course is possible to "apply" such a patch by hand, as a human can
read the intention out of such a patch. It however is impossible to apply
such a patch even manually in reverse, as the whole point of this option
is to omit the information necessary to do so from the output.

During a merge module_list returns conflicting submodules several times
(stage 1,2,3) which caused the submodules to be used multiple times in
git submodule init, sync, update and status command.
There are 5 callers of module_list; they all read (mode, sha1, stage,
path) tuple, and most of them care only about path. As a first level
approximation, it should be Ok (in the sense that it does not make things
worse than it currently is) to filter the duplicate paths from module_list
output, but some callers should change their behaviour when the merge in
the superproject still has conflicts.
Notice the higher-stage entries, and emit only one record from
module_list, but while doing so, mark the entry with "U" (not [0-3]) in
the $stage field and null out the SHA-1 part, as the object name for the
lowest stage does not give any useful information to the caller, and this
way any caller that uses the object name would hopefully barf. Then
update the codepaths for each subcommands this way:
- "update" should not touch the submodule repository, because we do not
know what commit should be checked out yet.
- "status" reports the conflicting submodules as 'U000...000' and does
not recurse into them (we might later want to make it recurse).
- The command called by "foreach" may want to do whatever it wants to do
by noticing the merged status in the superproject itself, so feed the
path to it from module_list as before, but only once per submodule.
- "init" and "sync" are unlikely things to do while the superproject is
still not merged, but as long as a submodule is there in $path, there
is no point skipping it. It might however want to take the merged
status of .gitmodules into account, but that is outside of the scope of
this topic.

The configuration created by plain --mirror is dangerous and

One alternative to this is to try to guess which type the
user wants. In a non-bare repository, a fetch mirror doesn't
make much sense, since it would overwrite local commits. But
in a bare repository, you might use either type, or even
both (e.g., if you are acting as an intermediate drop-point
across two disconnected networks).
So rather than try for complex heuristics, let's keep it
simple. The user knows what they're trying to do, so let

git-remote currently has one option, "--mirror", which sets
up mirror configuration which can be used for either
fetching or pushing. It looks like this:
[remote "mirror"]
url = wherever
fetch = +refs/*:refs/*
mirror = true
However, a remote like this can be dangerous and confusing.
Specifically:
1. If you issue the wrong command, it can be devastating.
You are not likely to "push" when you meant to "fetch",
but "git remote update" will try to fetch it, even if
you intended the remote only for pushing. In either
case, the results can be quite destructive. An
unintended push will overwrite or delete remote refs,
and an unintended fetch can overwrite local branches.
2. The tracking setup code can produce confusing results.
The fetch refspec above means that "git checkout -b new
master" will consider refs/heads/master to come from
the remote "mirror", even if you only ever intend to
push to the mirror. It will set up the "new" branch to
track mirror's refs/heads/master.
3. The push code tries to opportunistically update
tracking branches. If you "git push mirror foo:bar",
it will see that we are updating mirror's
refs/heads/bar, which corresponds to our local
refs/heads/bar, and will update our local branch.
To solve this, we split the concept into "push mirrors" and
"fetch mirrors". Push mirrors set only remote.*.mirror,
solving (2) and (3), and making an accidental fetch write
only into FETCH_HEAD. Fetch mirrors set only the fetch
refspec, meaning an accidental push will not force-overwrite
or delete refs on the remote end.
The new syntax is "--mirror=<fetch|push>". For
compatibility, we keep "--mirror" as-is, setting up both
types simultaneously.

It doesn't make sense to use "-m" on a mirror, since "-m"
sets up the HEAD symref in the remotes namespace, but with
mirror, we are by definition not using a remotes namespace.
Similarly, it does not make much sense to specify refspecs
with --mirror. For a mirror you plan to push to, those
refspecs will be ignored. For a mirror you are fetching
from, there is no point in mirroring, since the refspec
specifies everything you want to grab.
There is one case where "--mirror -t <X>" would be useful.
Because <X> is used as-is in the refspec, and because we
append it to to refs/, you could mirror a subset of the
hierarchy by doing:
git remote add --mirror -t 'tags/*'
But using anything besides a single branch as an argument to
"-t" is not documented and only happens to work, so closing
it off is not a serious regression.

Currently, "notes add" (without -f/--force) will abort when the given object
already has existing notes. This makes sense for the modes of "git notes add"
that would necessarily overwrite the old message (when using the -m/-F/-C/-c
options). However, when no options are given (meaning the notes are created
from scratch in the editor) it is not very user-friendly to abort on existing
notes, and forcing the user to run "git notes edit".
Instead, it is better to simply "redirect" to "git notes edit" automatically,
i.e. open the existing notes in the editor and let the user edit them.

* 'svn-fe' of git://repo.or.cz/git/jrn:
tests: kill backgrounded processes more robustly
vcs-svn: a void function shouldn't try to return something
tests: make sure input to sed is newline terminated
vcs-svn: add missing cast to printf argument
t0081 creates several background processes that write to a fifo and
then go to sleep for a while (so the reader of the fifo does not see
EOF).
Each background process is made in a curly-braced block in the shell,
and after we are done reading from the fifo, we use "kill $!" to kill
it off.
For a simple, single-command process, this works reliably and kills
the child sleep process. But for more complex commands like
"make_some_output && sleep", the results are less predictable. When
executing under bash, we end up with a subshell that gets killed by
the $! but leaves the sleep process still alive.
This is bad not only for process hygeine (we are leaving random sleep
processes to expire after a while), but also interacts badly with the
"prove" command. When prove executes a test, it does not realize the
test is done when it sees SIGCHLD, but rather waits until the test's
stdout pipe is closed. The orphaned sleep process may keep that pipe
open via test-lib's file descriptor 5, causing prove to hang for 100
seconds.
The solution is to explicitly use a subshell and to exec the final
sleep process, so that when we "kill $!" we get the process id of the
sleep process.
[jn: original patch by Jeff had some additional bits:
1. Wrap the "kill" in a test_when_finished, since we want
to clean up the process whether the test succeeds or not.
2. The "kill" is part of our && chain for test success. It
probably won't fail, but it can if the process has
expired before we manage to kill it. So let's mark it
as OK to fail.
I'm postponing that for now.]

Do not advertise no-done capability when upload-pack is not serving over

The fetch-pack/upload-pack protocol relies on the underlying transport
(local pipe or TCP socket) to have enough slack to allow one window worth
of data in flight without blocking the writer. Traditionally we always
relied on being able to have two windows of 32 "have"s in flight (roughly
3k bytes) to stream.
The recent "progressive-stride" change allows "fetch-pack" to send up to
1024 "have"s without reading any response from "upload-pack". The
outgoing pipe of "upload-pack" can be clogged with many ACK and NAK that
are unread, while "fetch-pack" is still stuffing its outgoing pipe with
more "have"s, leading to a deadlock.
Revert the change unless we are in stateless rpc (aka smart-http) mode, as
using a large window full of "have"s is still a good way to help reduce
the number of back-and-forth, and there is no buffering issue there (it is
strictly "ping-pong" without an overlap).
Signed-off-by: Junio C Hamano <gitster@pobox.com>
When 'no-done' protocol extension is used, the upload-pack (i.e. the
server side) process stops listening to the fetch-pack after issuing the
final NAK, and starts sending the generated pack data back, but there may
be more "have" send by the latter in flight that the fetch-pack is
expecting to be responded with ACK/NAK. This will typically result in a
deadlock (both will block on write that the other end never reads) or
SIGPIPE on the fetch-pack end (upload-pack will finish writing a small
pack and goes away).
Disable it unless fetch-pack is running under smart-http, where there is
no such streaming issue.

The copyfrom_target instruction copies appends data that is already

argument is relative to the beginning of output produced in the

The region copied is allowed to run past the end of the existing
output. To support that case, copy one character at a time rather
than calling memcpy or memmove. This allows copyfrom_target to be
used once to repeat a string many times. For example:
COPYFROM_DATA 2
COPYFROM_OUTPUT 10, 0
DATA "ab"
would produce the output "ababababababababababab".

Each window of an svndiff0-format delta includes a section for novel
text to be copied to the postimage (in the order it appears in the
window, possibly interspersed with other data).
Slurp in this data when encountering it. It is not actually necessary
to do so --- it would be just as easy to copy from delta to output
as part of interpreting the relevant instructions --- but this way,
the code that interprets svndiff0 instructions can proceed very
quickly because it does not require I/O.
Subversion's svndiff0 parser rejects deltas that do not consume all
the novel text that was provided. Omit that check for now so we can
test the new functionality right away, rather than waiting to learn
instructions that consume data.
Do check for truncated data sections. Subversion's parser rejects
deltas that end in the middle of a declared novel-text section, so it
should be safe for us to reject them, too.

The source view offset heading each svndiff0 window represents a
number of bytes past the beginning of the preimage. Together with the
source view length, it dictates to the delta applier what portion of
the preimage instructions will refer to. Read that portion right away
using the sliding window code.
Maybe some day we will use mmap to read data more lazily.
Subversion's implementation tolerates source view offsets pointing
past the end of the preimage file but we do not, for simplicity.
This does not teach the delta applier to read instructions or copy
data from the source view. Deltas that could produce nonempty output
will still be rejected.

source view offset
source view length
output length
instructions length
auxiliary data length
Parse it. The result is not usable for deltas with nonempty postimage

A delta in the subversion delta (svndiff0) format consists of the
magic bytes SVN\0 followed by a sequence of windows of a certain well
specified format (starting with five integers).
Add an svndiff0_apply function and test-svn-fe -d commandline tool to
parse such a delta in the special case of not including any windows.
Later patches will add features to turn this into a fully functional
delta applier for svn-fe to use to parse the streams produced by
"svnrdump dump" and "svnadmin dump --deltas".
The content of symlinks starts with the word "link " in Subversion's
worldview, so we need to be able to prepend that text to input for the
sake of delta application. So initialization of the input state of
the delta preimage is left to the calling program, giving callers a
chance to seed the buffer with text of their choice.

buffer_read_binary is a thin wrapper around fread, but its signature
is wrong:
- fread can fill an arbitrary in-memory buffer. buffer_read_binary
is limited to buffers whose size is representable by a 32-bit
integer.
- The result from fread is the number of bytes actually read.
buffer_read_binary only reports the number of bytes read by
incrementing sb->len by that amount and returns void.
Fix both: let buffer_read_binary accept a size_t instead of uint32_t
for the number of bytes to read and as a convenience return the number

Each section of a Subversion-format delta only requires examining (and
keeping in random-access memory) a small portion of the preimage. At
any moment, this portion starts at a certain file offset and has a
well-defined length, and as the delta is applied, the portion advances
from the beginning to the end of the preimage. Add a move_window
function to keep track of this view into the preimage.
You can use it like this:
buffer_init(f, NULL);
struct sliding_view window = SLIDING_VIEW_INIT(f);
move_window(&window, 3, 7); /* (1) */
move_window(&window, 5, 5); /* (2) */
move_window(&window, 12, 2); /* (3) */
strbuf_release(&window.buf);
buffer_deinit(f);
The data structure is called sliding_view instead of _window to
prevent confusion with svndiff0 Windows.
In this example, (1) reads 10 bytes and discards the first 3;
(2) discards the first 2, which are not needed any more; and (3) skips
2 bytes and reads 2 new bytes to work with.
When move_window returns, the file position indicator is at position
window->off + window->width and the data from positions window->off to
the current file position are stored in window->buf.
This function performs only sequential access from the input file and
never seeks, so it can be safely used on pipes and sockets.
On end-of-file, move_window silently reads less than the caller
requested. On other errors, it prints a message and returns -1.

svn-fe errors out on revision 59151 of the ASF repository:
fatal: invalid dump: unexpected end of file
The proximate cause is a property with an embedded NUL character.
Previously such anomalies were ignored but commit c9d1c8ba

uninitialized data when a property list ends early and unfortunately
this test does not distinguish between "foo" followed by EOF and the
string "foo\0bar\0baz".
Fix it by using buffer_read_binary to read to a strbuf and checking
the actual length read. Most consumers of properties still use
C-style strings, so in practice an author or log message with embedded
NULs will be truncated, but a least this way svn-fe won't error out
(fixing the regression).

When we merge into an unborn branch, there are basically two

1. Write the sha1 of the new commit into the ref pointed

2. Update the index with the new content, and check it out
to the working tree.
We currently do them in this order. However, (2) is the step
that is much more likely to fail, since it can be blocked by
things like untracked working tree files. When it does, the
merge fails and we are left with an empty index but an
updated HEAD.
This patch switches the order, so that a failure in updating
the index leaves us unchanged. Of course, a failure in
updating the ref now leaves us with an updated index and
mis-matched HEAD. That is arguably not much better, but it

Unlike bash and ksh, dash and busybox ash do not support brace
expansion (as in 'echo {hello,world}'). So when dash is sh,
t6009.13 (set up dodecapus) ends up pass a string beginning with
"root{1,2," to "git merge" verbatim and the test fails.
Fix it by introducing a variable to hold the list of parents for
the dodecapus and populating it in a more low-tech way.
While at it, simplify a little by combining this setup code with the
test it sets up for.

Since e9c8409 (diff-index --cached --raw: show tree entry on the LHS for
unmerged entries., 2007-01-05), an unmerged entry should be detected by
using DIFF_PAIR_UNMERGED(p), not by noticing both one and two sides of
the filepair records mode=0 entries. However, it forgot to update some
parts of the rename detection logic.
This only makes difference in the "diff --cached" codepath where an
unmerged filepair carries information on the entries that came from the
tree. It probably hasn't been noticed for a long time because nobody
would run "diff -M" during a conflict resolution, but "git status" uses
rename detection when it internally runs "diff-index" and "diff-files"
and gives nonsense results.
In an unmerged pair, "one" side can have a valid filespec to record the
tree entry (e.g. what's in HEAD) when running "diff --cached". This can
be used as a rename source to other paths in the index that are not
unmerged. The path that is unmerged by definition does not have the
final content yet (i.e. "two" side cannot have a valid filespec), so it
can never be a rename destination.
Use the DIFF_PAIR_UNMERGED() to detect unmerged filepair correctly, and
allow the valid "one" side of an unmerged filepair to be considered a
potential rename source, but never to be considered a rename destination.

The git-new-workdir script in contrib/ makes a new work tree by sharing
many subdirectories of the .git directory with the original repository.
When rerere.enabled is set in the original repository, but the user has
not encountered any conflicts yet, the original repository may not yet
have .git/rr-cache directory.
When rerere wants to run in a new work tree created from such a young
original repository, it fails to mkdir(2) .git/rr-cache that is a symlink
to a yet-to-be-created directory.
There are three possible approaches to this:
- A naive solution is not to create a symlink in the git-new-workdir
script to a directory the original does not have (yet). This is not a
solution, as we tend to lazily create subdirectories of .git/, and
having rerere.enabled configuration set is a strong indication that the
user _wants_ to have this lazy creation to happen;
- We could always create .git/rr-cache upon repository creation. This is
tempting but will not help people with existing repositories.
- Detect this case by seeing that mkdir(2) failed with EEXIST, checking
that the path is a symlink, and try running mkdir(2) on the link
target.
This patch solves the issue by doing the third one.
Strictly speaking, this is incomplete. It does not attempt to handle
relative symbolic link that points into the original repository, but this
is good enough to help people who use contrib/workdir/git-new-workdir
script.

Introduce --min-parents and --max-parents options which limit the
revisions to those commits which have at least (or at most) that many
commits, where negative arguments for --max-parents= denote infinity
(i.e. no upper limit).
In particular:
--max-parents=1 is the same as --no-merges;
--min-parents=2 is the same as --merges;
--max-parents=0 shows only roots; and
--min-parents=3 shows only octopus merges
Using --min-parents=n and --max-parents=m with n>m gives you what you ask
for (i.e. nothing) for obvious reasons, just like when you give --merges
(show only merge commits) and --no-merges (show only non-merge commits) at
the same time.
Also, introduce --no-min-parents and --no-max-parents to do the obvious
thing for convenience.
We compute the number of parents only when we limit by that, so there
is no performance impact when there are no limiters.

Use strbufs and strings instead of interned strings for values of rev,
dump, and node fields that happen to be strings. After this change,
the only remaining string_pool use is for paths in the repo_tree API
and internals.
Functional change: treat an empty author, UUID, or URL as none at all.
So for example, in repos where the first revision has an empty
svn:author property, the first rev will be treated as by "nobody"
rather than by a person with empty name and email address created by
prepending an @ sign to the repository UUID.

Current gcc + glibc with -D_FORTIFY_SOURCE try very aggressively to
protect against a programming style which uses write(...) without
checking the return value for errors. Even the usual hint of casting

Sometimes when there is an output error, especially right before exit,
there really is nothing to be done. The obvious solution, adopted in
v1.7.0.3~20^2 (run-command.c: fix build warnings on Ubuntu,
2010-01-30), is to save the return value to a dummy variable:
ssize_t dummy;
dummy = write(...);
But that (1) is ugly and (2) triggers -Wunused-but-set-variable
warnings with gcc-4.6 -Wall, so we are not much better off than when
we started.
Instead, use an "if" statement with an empty body to make the intent
clear.

Since v1.7.0-rc0~34 (make "mktag" a built-in, 2010-01-22), git mktag
uses the C99-style %td format to print ptrdiff_t values. It falls
back to %d when NO_C99_FORMAT is set, on the assumption that pre-C99
systems probably are using 32-bit pointers.
But many modern systems are 64-bit and
* sometimes one wants to test the NO_C99_FORMAT fallbacks using a
modern development platform;
* some platforms (I'm looking at you, msvc) have not gotten with the
program and are still C89-only.
These ptrdiff_t values are offsets from the beginning of a buffer, so
a size_t or uintmax_t would work about as well. Use the latter so we
can take advantage of the PRIuMAX fallback in git-compat-util.h, even
on C99-challenged systems with 64-bit pointers.

Variables from the inherited environment that are meaningful to git
can break tests in undesirable ways. For example,

test-lib, with a few exceptions:
- GIT_TRACE* are useful for tracking down bugs exhibited by a failing
test;
- GIT_DEBUG* are GIT_TRACE variables by another name, practically
speaking. They should probably be tweaked to follow the
GIT_TRACE_foo scheme and use trace_printf machinery some time.
- GIT_USE_LOOKUP from v1.5.6-rc0~134^2~1 (sha1-lookup: more memory

If the client requests both multi_ack_detailed and no-done then
upload-pack is free to immediately send a PACK following its first
'ACK %s ready' message. The upload-pack response actually winds
up being:
ACK %s common
... (maybe more) ...
ACK %s ready
NAK
ACK %s
PACK.... the pack stream ....
For smart HTTP connections this saves one HTTP RPC, reducing
the overall latency for a trivial fetch. For git:// and ssh://
a no-done option slightly reduces latency by removing one
server->client->server round-trip at the end of the common
ancestor negotiation.

If enabled on the connection "multi_ack_detailed no-done" as a
pair allows the remote upload-pack process to send a PACK down
to the client as soon as a "ACK %s ready" message was also sent.
Over git:// and ssh:// where a bi-directional stream is in place
this has very little difference over the classical version that
waits for the client to send a "done\n" line by itself. It does
slightly reduce the latency involved to start the pack stream as
there is one less round-trip from client->server required.
Over smart HTTP this avoids needing to send a final RPC that has
all of the prior common objects. Instead the server is able to
return a pack as soon as its ready to. For many common users the
smart HTTP fetch is now just 2 requests: GET .../info/refs, and
a POST .../git-upload-pack to not only negotiate but also receive
the pack stream. Only users who have more than 32 local unshared
commits with the remote will need additional requests to negotiate
a common merge base.

If a client is merely following the remote (and has not made any
new commits itself), all "have %s" lines sent by the client will be
common to the server. As all lines are common upload-pack never
calls ok_to_give_up() and does not compute if it has a good cut
point in the commit graph.
Without this computation the following client is going to send all
tagged commits, as these were determined to be COMMON_REF during the
initial advertisement, but the client does not parse their history
to transitively pass the COMMON flag and empty its queue of commits.
For git.git with 339 commit tags, it takes clients 11 rounds of
negotation to fully send all tagged commits and exhaust its queue
of things to send as common. This is pretty slow for a client that
has not done any local development activity.
Force computing ok_to_give_up() and send "ACK %s ready" at the end
of the current round if this round only contained common objects
and ok_to_give_up() was therefore not called. This may allow the
client to break early, avoiding transmission of the COMMON_REFs.

If multi_ack_detailed was selected in the protocol capabilities
(both client and server are >= Git 1.6.6) the upload-pack side will
send "ACK %s ready" when it knows how to safely cut the graph and
produce a reasonable pack for the want list that was already sent
on the connection.
Upon receiving "ACK %s ready" there is no point in looking at
the remaining commits inside of rev_list. Sending additional
"have %s" lines to the remote will not construct a smaller pack.
It is unlikely a commit older than the current cut point will have
a better delta base than the cut point itself has.
The original design of this code had fetch-pack empty rev_list by
marking a commit and its transitive ancestors COMMON whenever the
remote side said "ACK %s {continue,common}" and skipping over any
already COMMON commits during get_rev(). This approach does not
work when most of rev_list is actually COMMON_REF, commits that
are pointed to by a reference on the remote, which exist locally,
and which have not yet been sent to the remote as a "have %s" line.
Most of the common references are tags in the ref/tags namespace,
using points in the commit graph that are more than 1 commit apart.
In git.git itself, this is currently 340 tags, 339 of which point to
commits in the commit graph. fetch-pack pushes all of these into
rev_list, but is unable to mark them COMMON and discard during a
remote's "ACK %s {continue,common}" because it does not parse through
the entire parent chain. Not parsing the entire parent chain is
an optimization to avoid walking back to the roots of the repository.
Assuming the client is only following the remote (and does not make
its own local commits), the client needs 11 rounds to spin through
the entire list of tags (32 commits per round, ceil(339/32) == 11).
Unfortunately the server knows on the first "have %s" line that
it can produce a good pack, and does not need to see the remaining
320 tags in the other 10 rounds.
Over git:// and ssh:// this isn't as bad as it sounds, the client is
only transmitting an extra 16,000 bytes that it doesn't need to send.
Over smart HTTP, the client must do an additional 10 HTTP POST
requests, each of which incurs round-trip latency, and must upload
the entire state vector of all known common objects. On the final
POST request, this is 16 KiB worth of data.
Fix all of this by clearing rev_list as soon as the remote side
says it can construct a pack.

There is a nice shortlog-ish output of the authors there. We
also point people directly to shortlog, but of course they
might be reading the documentation online or from a binary
package of git.
The default of 7 comes from fairly early in git development, when
seven hex digits was a lot (it covers about 250+ million hash
values). Back then I thought that 65k revisions was a lot (it was what
we were about to hit in BK), and each revision tends to be about 5-10
new objects or so, so a million objects was a big number.
These days, the kernel isn't even the largest git project, and even
the kernel has about 220k revisions (_much_ bigger than the BK tree
ever was) and we are approaching two million objects. At that point,
seven hex digits is still unique for a lot of them, but when we're
talking about just two orders of magnitude difference between number
of objects and the hash size, there _will_ be collisions in truncated
hash values. It's no longer even close to unrealistic - it happens all
the time.
We should both increase the default abbrev that was unrealistically
small, _and_ add a way for people to set their own default per-project
in the git config file.
This is the first step to first make it configurable; the default of 7
is not raised yet.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.
While doing a final sanity check before merging a topic Bsomething, it
is a good idea to review what damage Bsomething branch would make, by
running:
$ git diff ...Bsomething
Unfortunately, our completion script for 'git diff' doesn't offer
anything after '...'. This is because 'git diff's completion function
invokes __git_complete_file() for non-option arguments to complete the
'<tree>:<path>' extended SHA-1 notation, but this helper function
doesn't support refs after '...' or '..'. Completion of refs after
'...' or '..' is supported by the __git_complete_revlist() helper
function, but that doesn't support '<tree>:<path>'.
To support both '...<ref>' and '<tree>:<path>' notations for 'git
diff', this patch, instead of adding yet another helper function,
joins __git_complete_file() and __git_complete_revlist() into the new
common function __git_complete_revlist_file(). The old helper
functions __git_complete_file() and __git_complete_revlist() are
changed to be a direct wrapper around the new
__git_complete_revlist_file(), because they might be used in
user-supplied completion scripts and we don't want to break them.
This change will cause some wrong suggestions for other commands which
use __git_complete_file() ('git diff' and friends) or
__git_complete_revlist() ('git log' and friends), e.g. 'git diff
...master:Doc<TAB>' and 'git log master:Doc<TAB>' will complete the
path to 'Documentation/', although neither commands make any sense.
However, both of these were actively wrong to begin with as soon as
the user entered the ':', so there is no real harm done.

The Q_ function translates a string representing some pharse with an
alternative plural form and uses the 'count' argument to choose which
form to return. Use of Q_ solves the "%d noun(s)" problem in a way
that is portable to languages outside the Germanic and Romance
families.
In English, the semantics of Q_(sing, plur, count) are roughly
equivalent to
count == 1 ? _(sing) : _(plur)
while in other languages there can be more variants (count == 0; more
random-looking rules based on the historical pronunciation of the
number). Behind the scenes, the singular form is used to look up a
family of translations and the plural form is ignored unless no
translation is available.
Define such a Q_ in gettext.h with the English semantics so C code can
start using it to mark phrases with a count for translation.
The name "Q_" is taken from subversion and stands for "quantity".
Many projects just use ngettext directly without a wrapper analogous
to _; we should not do so because git's gettext.h is meant not to
conflict with system headers that might include libintl.h.

Until now the --recurse-submodules option could only be used to either
fetch all populated submodules recursively or to disable recursion
completely. As fetch and pull now by default just fetch those submodules
for which new commits have been fetched in the superproject, a command
line option to enforce that behavior is needed to be able to override
configuration settings.

To be able to access all commits of populated submodules referenced by the
superproject it is sufficient to only then let "git fetch" recurse into a
submodule when the new commits fetched in the superproject record new
commits for it. Having these commits present is extremely useful when
using the "--submodule" option to "git diff" (which is what "git gui" and
"gitk" do since 1.6.6), as all submodule commits needed for creating a
descriptive output can be accessed. Also merging submodule commits (added
in 1.7.3) depends on the submodule commits in question being present to
work. Last but not least this enables disconnected operation when using
submodules, as all commits necessary for a successful "git submodule
update -N" will have been fetched automatically. So we choose this mode as
the default for fetch and pull.
Before a new or changed ref from upstream is updated in update_local_ref()
"git rev-list <new-sha1> --not --branches --remotes" is used to determine
all newly fetched commits. These are then walked and diffed against their
parent(s) to see if a submodule has been changed. If that is the case, its
path is stored to be fetched after the superproject fetch is completed.
Using the "--recurse-submodules" or the "--no-recurse-submodules" option
disables the examination of the fetched refs because the result will be
ignored anyway.
There is currently no infrastructure for storing deleted and new
submodules in the .git directory of the superproject. That's why fetch and
pull for now only fetch submodules that are already checked out and are
not renamed.
In t7403 the "--no-recurse-submodules" argument had to be added to "git
pull" to avoid failure because of the moved upstream submodule repo.

To keep the code changes simple, we operate at the lowest

packets. The one exception is a packet starting with "PACK",
which causes us to skip that packet and turn off tracing
(since the gigantic pack data will not be interesting to
read, at least not in the trace format).
We show both written and read packets. In the local case,
this may mean you will see packets twice (written by the
sender and read by the receiver). However, for cases where
the other end is remote, this allows you to see the full
conversation.

Tweak the GETTEXT_POISON facility so it is activated at run time
instead of compile time. If the GIT_GETTEXT_POISON environment
variable is set, _(msg) will result in gibberish as before; but if the
GIT_GETTEXT_POISON variable is not set, it will return the message for
human-readable output. So the behavior of mistranslated and
untranslated git can be compared without rebuilding git in between.
For simplicity we always set the GIT_GETTEXT_POISON variable in tests.

Add a new GETTEXT_POISON compile-time parameter to make _(msg) always
return gibberish. So now you can run
make GETTEXT_POISON=YesPlease
to get a copy of git that functions correctly (one hopes) but produces
output that is in nobody's native language at all.
This is a debugging aid for people who are working on the i18n part of
the system, to make sure that they are not marking plumbing messages
that should never be translated with _().
As new strings get marked for translation, naturally a number of tests
will be broken in this mode. Tests that depend on output from
Porcelain will need to be marked with the new C_LOCALE_OUTPUT test
prerequisite. Newly failing tests that do not depend on output from
Porcelain would be bugs due to messages that should not have been
marked for translation.
Note that the string we're using ("# GETTEXT POISON #") intentionally
starts the pound sign. Some of Git's tests such as
t3404-rebase-interactive.sh rely on interactive editing with a fake
editor, and will needlessly break if the message doesn't start with
something the interactive editor considers a comment.
A future patch will fix fix the underlying cause of that issue by

The _ function is for translating strings into the user's chosen
language. The N_ macro just marks translatable strings for the
xgettext(1) tool without translating them; it is intended for use in
contexts where a function call cannot be used. So, for example:
fprintf(stderr, _("Expansion of alias '%s' failed; "
"'%s' is not a git command\n"),
cmd, argv[0]);
and
const char *unpack_plumbing_errors[NB_UNPACK_TREES_ERROR_TYPES] = {
/* ERROR_WOULD_OVERWRITE */
N_("Entry '%s' would be overwritten by merge. Cannot merge."),
[...]
Define such _ and N_ in a new gettext.h and include it in cache.h, so
they can be used everywhere. Each just returns its argument for now.
_ is a function rather than a macro like N_ to avoid the temptation to
use _("foo") as a string literal (which would be a compile-time error
once _(s) expands to an expression for the translation of s).

Rely on fast-import for information about previous revs.
This requires always setting up backward flow of information, even for
v2 dumps. On the plus side, it simplifies the code by quite a bit and
opens the door to further simplifications.

Current svn-fe produces output like this:
blob
mark :7382321
data 5
hello
blob
mark :7382322
data 5
Hello
commit
mark :3
[...]
M 100644 :7382321 hello.c
M 100644 :7382322 hello2.c
This means svn-fe has to keep track of the paths modified in each
commit and the corresponding marks, instead of dealing with each file
as it arrives in input and then forgetting about it. A better
strategy would be to use inline blobs:
commit
mark :3
[...]
M 100644 inline hello.c
data 5
hello
[...]
As a first step towards that, teach svn-fe to notice when the
collection of blobs for each commit starts and write a comment
("# commit 3.") there.

Prepare to use mark :5 for the commit corresponding to r5 (and so on).
1 billion seems sufficiently high for blob marks to avoid conflicting
with rev marks, while still leaving room for 3 billion blobs. Such
high mark numbers cause trouble with ancient fast-import versions, but
this topic cannot support git fast-import versions before 1.7.4 (which
introduces the cat-blob command) anyway.

Set up some plumbing: teach the svndump lib to pass a file descriptor
number to the fast_export lib, representing where cat-blob/ls
responses can be read from, and add a get_response_line helper
function to the fast_export lib to read a line from that file.
Unfortunately this means that svn-fe needs file descriptor 3 to be
redirected from somewhere (preferrably the cat-blob stream of a
fast-import backend); otherwise it will fail:
$ svndump <path> | svn-fe
fatal: cannot read from file descriptor 3: Bad file descriptor
For the moment, "svn-fe 3</dev/null" works as a workaround but it
will not work for very long. A fast-import backend that can retrieve
old commits is needed in order to be able to fulfill svn
"Node-copyfrom-rev" requests that refer to revs from a previous run.

svn-fe processes each commit in two stages: first decide on the
correct content for all paths and export the relevant blobs, then
export a commit with the result.
But we can keep less state and simplify svn-fe a great deal by
exporting the commit in one step: use 'inline' blobs for each path and
remember nothing. This way, the repo_tree structure could be
eliminated, and we would get support for incremental imports 'for
free'.
Reorganize handle_node along these lines. This is just a code
cleanup; the changes in repo_tree and handle_revision will come later.

The repo_tree structure remembers, for each path in each revision, a
mode (regular file, executable, symlink, or directory) and content
(blob mark or directory structure). Maintaining a second copy of all
this information when it's already in the target repository is
wasteful, it does not persist between svn-fe invocations, and most
importantly, there is no convenient way to transfer it from one
machine to another. So it would be nice to get rid of it.
As a first step, let's change the repo_tree API to match fast-import's
read commands more closely. Currently to read the mode for a path,
one uses
repo_modify_path(path, new_mode, new_content);
which changes the mode and content as a side effect. There is no
function to read the content at a path; add one.

Interactive rebase used to have its own command line processing. Since
it used the 'git rev-parse --parseopt' functionality exposed through
git-sh-setup, it had some flexibility, like matching prefixes of long
options, that non-interactive rebase didn't. When interactive rebase's
command line processing was factored out into git-rebase.sh in cf432ca
(rebase: factor out command line option processing, 2011-02-06), this
flexibility was lost. Give back that flexibility to interactive and
non-interactive by defining its options in OPTIONS_SPEC.

In 882fd11 (merge-recursive: Delay content merging for renames 2010-09-20),
there was code that checked for whether we could skip updating a file in
the working directory, based on whether the merged version matched the
current working copy. Due to the desire to handle directory/file conflicts
that were resolvable, that commit deferred content merging by first
updating the index with the unmerged entries and then moving the actual
merging (along with the skip-the-content-update check) to another function
that ran later in the merge process. As part moving the content merging
code, a bug was introduced such that although the message about skipping
the update would be printed (whenever GIT_MERGE_VERBOSITY was sufficiently
high), the file would be unconditionally updated in the working copy
anyway.
When we detect that the file does not need to be updated in the working
copy, update the index appropriately and then return early before updating
the working copy.

A pack v2 .idx file usually records offset using 64-bit representation
only when the offset does not fit within 31-bit, but you can handcraft
your .idx file to record smaller offset using 64-bit, storing all zero
in the upper 4-byte. By inspecting the original idx file when running
index-pack --verify, encode such low offsets that do not need to be in
64-bit but are encoded using 64-bit just like the original idx file so
that we can still validate the pack/idx pair by comparing the idx file
recomputed with the original.

Given an existing .pack file and the .idx file that describes it,
this new mode of operation reads and re-index the packfile and makes
sure the existing .idx file matches the result byte-for-byte.
All the objects in the .pack file are validated during this operation as
well. Unlike verify-pack, which visits each object described in the .idx
file in the SHA-1 order, index-pack efficiently exploits the delta-chain
to avoid rebuilding the objects that are used as the base of deltified
objects over and over again while validating the objects, resulting in
much quicker verification of the .pack file and its .idx file.
This version however cannot verify a .pack/.idx pair with a handcrafted v2
index that uses 64-bit offset representation for offsets that would fit
within 31-bit. You can create such an .idx file by giving a custom offset
to --index-version option to the command.

Entries in the delta_base array are only grouped by the bytepattern in
the delta_base union, some of which have 20-byte object name of the base
object (i.e. base for REF_DELTA objects), while others have sizeof(off_t)
bytes followed by enough NULs to fill 20-byte. The loops to iterate
through a range inside this array still needs to inspect the type of the
delta, and skip over false hits.

It can sometimes be useful to write information temporarily to file,
to read back later. These functions allow a program to use the
line_buffer facilities when doing so.
It works like this:
1. find a unique filename with buffer_tmpfile_init.
2. rewind with buffer_tmpfile_rewind. This returns a stdio
handle for writing.
3. when finished writing, declare so with
buffer_tmpfile_prepare_to_read. The return value indicates
how many bytes were written.
4. read whatever portion of the file is needed.
5. if finished, remove the temporary file with buffer_deinit.
otherwise, go back to step 2,
The svn support would use this to buffer the postimage from delta
application until the length is known and fast-import can receive
the resulting blob.

buffer_read_char can be used in place of buffer_read_string(1) to
avoid consuming valuable static buffer space. The delta applier will
use this to read variable-length integers one byte at a time.
Underneath, it is fgetc, wrapped so the line_buffer library can
maintain its role as gatekeeper of input.
Later it might be worth checking if fgetc_unlocked is faster ---
most line_buffer functions are not thread-safe anyway.

buffer_read_string works well for non line-oriented input except for
one problem: it does not tell the caller how many bytes were actually
written. This means that unless one is very careful about checking
for errors (and eof) the calling program cannot tell the difference
between the string "foo" followed by an early end of file and the
string "foo\0bar\0baz".
So introduce a variant that reports the length, too, a thinner wrapper
around strbuf_fread. Its result is written to a strbuf so the caller
does not need to keep track of the number of bytes read.

POSIX makes the behavior of read(2) from a pipe fairly clear: a read
from an empty pipe will block until there is data available and any
other read will not block, prefering to return a partial result.
Likewise, fread(3) and fgets(3) are clearly specified to act as
though implemented by calling fgetc(3) in a simple loop. But the
buffering behavior of fgetc is less clear.
Luckily, no sane platform is going to implement fgetc by calling the
equivalent of read(2) more than once. fgetc has to be able to
return without filling its buffer to preserve errno when errors are
encountered anyway. So let's assume the simpler behavior (trust) but
add some tests to catch insane platforms that violate that when they
come (verify).
First check that fread can handle a 0-length read from an empty fifo.
Because open(O_RDONLY) blocks until the writing end is open, open the
writing end of the fifo in advance in a subshell.
Next try short inputs from a pipe that is not filled all the way.
Lastly (two tests) try very large inputs from a pipe that will not fit
in the relevant buffers. The first of these tests reads a little
more than 8192 bytes, which is BUFSIZ (the size of stdio's buffers)
on this Linux machine. The second reads a little over 64 KiB (the
pipe capacity on Linux) and is not run unless requested by setting
the GIT_REMOTE_SVN_TEST_BIG_FILES environment variable.

Lazy fast-import frontend authors that want to rely on the backend to
keep track of the content of the imported trees _almost_ have what
they need in the 'cat-blob' command (v1.7.4-rc0~30^2~3, 2010-11-28).
But it is not quite enough, since
(1) cat-blob can be used to retrieve the content of files, but
not their mode, and
(2) using cat-blob requires the frontend to keep track of a name
(mark number or object id) for each blob to be retrieved
Introduce an 'ls' command to complement cat-blob and take care of the
remaining needs. The 'ls' command finds what is at a given path
within a given tree-ish (tag, commit, or tree):
'ls' SP <dataref> SP <path> LF
or in fast-import's active commit:
'ls' SP <path> LF
The response is a single line sent through the cat-blob channel,
imitating ls-tree output. So for example:
FE> ls :1 Documentation
gfi> 040000 tree 9e6c2b599341d28a2a375f8207507e0a2a627fe9 Documentation
FE> ls 9e6c2b599341d28a2a375f8207507e0a2a627fe9 git-fast-import.txt
gfi> 100644 blob 4f92954396e3f0f97e75b6838a5635b583708870 git-fast-import.txt
FE> ls :1 RelNotes
gfi> 120000 blob b942e49944 RelNotes
FE> cat-blob b942e49944
gfi> b942e49944 blob 32
gfi> Documentation/RelNotes/1.7.4.txt
The most interesting parts of the reply are the first word, which is
a 6-digit octal mode (regular file, executable, symlink, directory,
or submodule), and the part from the second space to the tab, which is
a <dataref> that can be used in later cat-blob, ls, and filemodify (M)
commands to refer to the content (blob, tree, or commit) at that path.
If there is nothing there, the response is "missing some/path".
The intent is for this command to be used to read files from the
active commit, so a frontend can apply patches to them, and to copy
files and directories from previous revisions.
For example, proposed updates to svn-fe use this command in place of
its internal representation of the repository directory structure.
This simplifies the frontend a great deal and means support for
resuming an import in a separate fast-import run (i.e., incremental
import) is basically free.

obj_pool is inherently global and does not use the standard growing
factor alloc_nr, which makes it feel out of place in the git codebase.
Plus it is overkill for this application: all that is needed is a
buffer that can grow between requests to accomodate larger strings.
Use a strbuf instead.
As a side effect, this improves the error handling: allocation
failures will result in a clean exit instead of segfaults. It would
be nice to add a test case (using ulimit or failmalloc) but that can

In a variable-args function, the code for writing into a strbuf is

You can detach the HEAD at an arbitrary commit in order to browse the
files in various points in the history or build older versions of the
software, without recording any new commit, and come back to an existing
branch. When used in this "sightseer" mode, detached HEAD is a perfectly
safe mechanism. It also is a useful state to experiment with throw-away
commits.
When coming back to an existing branch with "git checkout master",
however, the commits that were created on the detached HEAD will become
unreachable from anywhere but the reflog of the HEAD. Check if the commit
we are about to leave is connected to some ref, and give a final warning
otherwise to remind the user for safety.

Subject and identity headers may be arbitrarily long. In the
past, we just assumed that single-line headers would be
reasonably short. For multi-line subjects that we squish
into a single line, we just "pre-folded" the data in
pp_title_line by adding a newline and indentation.
There were two problems. One is that, although rare,
single-line messages can actually be longer than the
recommended line-length limits. The second is that the
pre-folding interacted badly with rfc2047 encoding, leading
to malformed headers.
Instead, let's stop pre-folding the subject lines, and just
fold everything based on length in add_rfc2047, whether
it is encoded or not.

The function strbuf_add_wrapped_text takes a NUL-terminated
string. This makes it annoying to wrap strings we have as a
pointer and a length.
Refactoring strbuf_add_wrapped_text and all of its
sub-functions to handle fixed-length strings turned out to
be really ugly. So this implementation is lame; it just
strdups the text and operates on the NUL-terminated version.
This should be fine as the strings we are wrapping are
generally pretty short. If it becomes a problem, we can
optimize later.

Sanity-check config variable names when adding and retrieving them. As a side

Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).
On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.
In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.
A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:
$ git commit -c CHERRY_PICK_HEAD
A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

There are a few new things to consider, though:
1. Average processors are faster now.
2. We've seen on the mailing list some ugly merges where
not using inexact rename detection leads to many more
conflicts. Merges of this size take a long time
anyway, so users are probably happy to spend a little
bit of time computing the renames.

Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.
Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.
file1: file does not need merging
Continue merging other unresolved paths (y/n) ?
Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was
introduced in the previous commit.

After "rerere" resolves conflicts by reusing old resolution, there would
be three kinds of paths with conflict in the index:
* paths that have been resolved in the working tree by rerere;
* paths that need further work whose resolution could be recorded;
* paths that need resolving that rerere won't help.
When the user wants a list of paths that need hand-resolving, output from
"rerere status" does not help, as it shows only the second category, but
the paths in the third category still needs work (rerere only makes sense
for regular files that have both our side and their side, and does not
help other kinds of conflicts, e.g. "we modified, they deleted").
The new subcommand "rerere remaining" can be used to show both. As
opposed to "rerere status", this subcommand also skips printing paths
that have been added to the index, since these paths are already
resolved and are no longer "remaining".
Initial patch provided by Junio. Refactored and modified to skip
resolved paths by Martin. Commit message mostly by Junio.

Some HTTP/1.1 servers or proxies don't correctly implement the
100-Continue feature of HTTP/1.1. Its a difficult feature to
implement right, and isn't commonly used by browsers, so many
developers may not even be aware that their server (or proxy)
doesn't honor it.
Within the smart HTTP protocol for Git we only use this newer
"Expect: 100-Continue" feature to probe for missing authentication
before uploading a large payload like a pack file during push.
If authentication is necessary, we expect the server to send the
401 Not Authorized response before the bulk data transfer starts,
thus saving the client bandwidth during the retry.
A different method to probe for working authentication is to send an
empty command list (that is just "0000") to $URL/git-receive-pack.
or $URL/git-upload-pack. All versions of both receive-pack and
upload-pack since the introduction of smart HTTP in Git 1.6.6
cleanly accept just a flush-pkt under --stateless-rpc mode, and
exit with success.
If HTTP level authentication is successful, the backend will return
an empty response, but with HTTP status code 200. This enables
the client to continue with the transfer.

'git rebase' without arguments is currently not supported. Make it
default to 'git rebase @{upstream}'. That is also what 'git pull
[--rebase]' defaults to, so it only makes sense that 'git rebase'
defaults to the same thing.
Defaulting to @{upstream} will make it possible to run e.g. 'git
rebase -i' without arguments, which is probably a quite common use
case. It also improves the scenario where you have multiple branches
that rebase against a remote-tracking branch, where you currently have
to choose between the extra network delay of 'git pull' or the
slightly awkward keys to enter 'git rebase @{u}'.
The error reporting when no upstream is configured for the current
branch or when no branch is checked out is reused from git-pull.sh. A
function is extracted into git-parse-remote.sh for this purpose.

cases. When reading, try to read from orig-head. If that fails, read

Detect early on if a rebase is in progress and what type of rebase it
is (interactive, merge-based or am-based). This prepares for further

later also make it easier to dispatch to the type-specific scripts.
Also show a consistent error message independent of the type of rebase

The code reading the state saved in $merge_dir or $rebase_dir is
currently spread out in many places, making it harder to read and to
introduce additional state. Extract this code into one method that
reads the state. Only extract the code associated with the state that
is written when the rebase is initiated. Leave the state that changes
for each commmit, at least for now.
Currently, when resuming a merge-based rebase using --continue or
--skip, move_to_original_branch (via finish_rb_merge) will be called
without head_name and orig_head set. These variables are then lazily
read in move_to_original_branch if head_name is not set (together with
onto, which is unnecessarily read again). Change this by always
eagerly reading the state, for both am-based and merge-based rebase,
in the --continue and --skip cases. Note that this does not change the
behavior for am-based rebase, which read the state eagerly even before
this commit.
Reading the state eagerly means that part of the state will sometimes
be read unnecessarily. One example is when the rebase is continued,
but stops again at another merge conflict. Another example is when the
rebase is aborted. However, since both of these cases involve user
interaction, the delay is hopefully not noticeable. The
call_merge/continue_merge loop is not affected.

On Windows in case a program is accessing a file unlink or
move operations may fail. To give the user a chance to correct
this we simply wait until the user asks us to retry or fail.
This is useful because of the following use case which seem
to happen rarely but when it does it is a mess:
After making some changes the user realizes that he was on the
incorrect branch. When trying to change the branch some file
is still in use by some other process and git stops in the
middle of changing branches. Now the user has lots of files
with changes mixed with his own. This is especially confusing
on repositories that contain lots of files.
Although the recent implementation of automatic retry makes
this scenario much more unlikely lets provide a fallback as
a last resort.
Thanks to Albert Dvornik for disabling the question if users can't see it.
If the stdout of the command is connected to a terminal but the stderr
has been redirected, the odds are good that the user can't see any
question we print out to stderr. This will result in a "mysterious
hang" while the app is waiting for user input.
It seems better to be conservative, and avoid asking for input
whenever the stderr is not a terminal, just like we do for stdin.

When starting git gui in a non-git directory it presents the user a
dialog which asks to create, clone or open a repository. The filedialogs
used to choose the path(s) would always default to the home directory of
the user. This patch changes this behavior and uses the current working
directory in which git gui was started as default.
This is useful in various cases. First being that the user starts the
gui in some directory and can go search to create, open or clone a
repository from there. Another use case is that tools like filemanager
context menues can transport a natural default when selected from a
folder.

git's diff-words support has a detail that can be a little dangerous:
any text not matched by a given language's tokenization pattern is
treated as whitespace and changes in such text would go unnoticed.
Therefore each of the built-in regexes allows a special token type
consisting of a single non-whitespace character [^[:space:]].
To make sure UTF-8 sequences remain human readable, the builtin
regexes also have a special token type for runs of bytes with the high
bit set. In English, non-ASCII characters are usually isolated so
this is analogous to the [^[:space:]] pattern, except it matches a
single _multibyte_ character despite use of the C locale.
Unfortunately it is easy to make typos or forget entirely to include
these catch-all token types when adding support for new languages (see
v1.7.3.5~16, userdiff: fix typo in ruby and python word regexes,
2010-12-18). Avoid this by including them automatically within the
PATTERNS and IPATTERN macros.
While at it, change the UTF-8 sequence token type to match exactly one
non-ASCII multi-byte character, rather than an arbitrary run of them.

The builtin word regexes should be tested with some simple examples
against simple issues. Do this in bulk.
Mainly due to a lack of language knowledge and inspiration, most of
the test cases (cpp, csharp, java, objc, pascal, php, python, ruby)
are directly based off a C operator precedence table to verify that
all operators are split correctly. This means that they are probably
incomplete or inaccurate except for 'cpp' itself.
Still, they are good enough to already have uncovered a typo in the
python and ruby patterns.
'fortran' is based on my anecdotal knowledge of the DO10I parsing
rules, and thus probably useless. The rest (bibtex, html, tex) are an
ad-hoc test of what I consider important splits in those languages.

When a frontend uses a marks file to ensure its state persists between
runs, it may represent "clean slate" when bootstrapping with "no marks
yet". In such a case, feeding the last state with --import-marks and
saving the state after the current run with --export-marks would be a
natural thing to do.
The --import-marks option however errors out when the specified marks file
doesn't exist; this makes bootstrapping a bit difficult. The location of
the marks file becomes backend-dependent when --relative-marks is in
effect, and the frontend cannot check for the existence of the file in
such a case.
The --import-marks-if-exists option does the same thing as --import-marks
but does not flag an error if the named file does not exist yet to help

there or nothing at all. If that lstat call fails (for example due to
ENOMEM), it assumes ENOENT, meaning a directory with untracked files
would be clobbered in that case.
Check errno after calling lstat, and for conditions other than ENOENT,
just error out.
This is a theoretical race condition. lstat has to succeed moments
before it fails for there to be trouble.

On Windows, system() executes with cmd.exe instead of /bin/sh. This
means that aliases currently has to be batch-scripts instead of
bourne-scripts. On top of that, cmd.exe does not handle single quotes,
which is what the code-path currently uses to handle arguments with
spaces.
To solve both problems in one go, use run_command_v_opt() to execute
the alias. It already does the right thing prepend "sh -c " to the
alias.

unpack_trees() merges two trees (the current HEAD and the destination
commit) when switching to another branch, checking and updating the index
entry where the destination differs from the current HEAD. It merges three
trees (the common ancestor, the current HEAD and the other commit) when
performing a three-way merge, checking and updating the index entry when
the merge result differs from the current HEAD. It does so by walking the
input trees in parallel all the way down to the leaves.
One common special case is a directory is identical across the trees
involved in the merge. In such a case, we do not have to descend into the
directory at all---we know that the end result is to keep the entries in
the current index.
This optimization cannot be applied in a few special cases in
unpack_trees(), though. We need to descend into the directory and update
the index entries from the target tree in the following cases:
- When resetting (e.g. "git reset --hard"); and
- When checking out a tree for the first time into an empty working tree
(e.g. "git read-tree -m -u HEAD HEAD" with missing .git/index).

For example, this would allow cherry-picking or reverting patches from
a piece of history with a different end-of-line style, like so:
$ git revert -Xrenormalize old-problematic-commit
Currently that is possible with manual use of merge-recursive but the
cherry-pick/revert porcelain does not expose the functionality.

It is not uncommon for a svn repository to include change records for
properties at the top level of the tracked tree:
Node-path:
Node-kind: dir
Node-action: change
Prop-delta: true
Prop-content-length: 43
Content-length: 43
K 10
svn:ignore
V 11
build-area
PROPS-END
Unfortunately a recent svn-fe change (vcs-svn: More dump format sanity
checks, 2010-11-19) causes such nodes to be rejected with the error
message
fatal: invalid dump: path to be modified is missing
The repo_tree module does not keep a dirent for the root of the tree.

The rules for what file is used as delta source for each file are not
documented in dump-load-format.txt. Luckily, the Apache Software
Foundation repository has rich enough examples to figure out most of
the rules:
Node-action: replace implies the empty property set and empty text as
preimage for deltas. Otherwise, if a copyfrom source is given, that
node is the preimage for deltas. Lastly, if none of the above applies
and the node path exists in the current revision, then that version
forms the basis.

Node-action: change is not appropriate when switching between file and
directory or adding a new file. Current svn-fe silently accepts such
nodes and the resulting tree has missing files in the "changed when
meant to add" case.
Node-action: add requires some content (text or directory); there is
no such thing as an "intent to add" node in svn dumps. Current svn-fe
accepts such contentless adds but produces an invalid fast-import
stream that refers to nonexistent mark :0 in response.

The mode for each file in an svn-format dump is kept in the properties
section. The properties section is read as soon as possible to allow
the correct mode to be filled in when registering the file with the
repo_tree lib.
To support nodes with a missing properties section, svn-fe determines
the mode in three stages:
- The kind (directory or file) of the node is read from the dump and
used to make an initial estimate (040000 or 100644).
- Properties are read in and allowed to override this for symlinks
and executables.
- If there is no properties section, the mode from the previous
content of the path is left alone, overriding the above
considerations.
This is a bit of a mess, and worse, it would get even more complicated
once we start to support property deltas. If we could only register
the file with a provisional value for mode and then change it later
when properties say so, the procedure would be much simpler.
... oh, right, we can.

There are two functions to change the staged content for a path in the
svn importer's active commit: repo_replace, which changes the text and
returns the mode, and repo_modify, which changes the text and mode and
returns nothing.
Worse, there are more subtle differences:
- A mark of 0 passed to repo_modify means "use the existing content".
repo_replace uses it as mark :0 and produces a corrupt stream.
- When passed a path that is not part of the active commit,
repo_replace returns without doing anything. repo_modify
transparently adds a new directory entry.
Get rid of both and introduce a new function with the best features of
both: repo_modify_path modifies the mode, content, or both for a path,
depending on which arguments are zero. If no such dirent already
exists, it does nothing and reports the error by returning 0.
Otherwise, the return value is the resulting mode.

Allocate a mark if needed as soon as possible so later code can use
"if (mark)" to check if this node has text attached rather than
explicitly checking for Text-content-length.
While at it, reject directory nodes with text attached; the presence
of such a node would indicate a bug in the dump generator or svn-fe's
understanding. In the long term, it would be nice to be able to
continue parsing and save the error for later, but for now it is

It is possible for a path node in an SVN-format dump file to leave out
the properties section. svn-fe handles this by carrying over the
properties (in particular, file type) from the old version of that
node.
To support this, handle_node tests several times whether a
Prop-content-length field is present. Ancient Subversion actually
leaves out the Prop-content-length field even for nodes with
properties, so that's not quite the right check. Besides, this detail
of mechanism is distracting when the question at hand is instead what
content the new node should have.
So introduce a local have_props variable. The semantics are the same
as before; the adaptations to support ancient streams that leave out
the prop-content-length can wait until someone needs them.

The mark variable is only used in handle_node(). Its life is
very short and simple: first, a new mark number is allocated if
this node has text attached, then that mark is recorded in the
in-core tree being built up, and lastly the mark is communicated
to fast-import in the stream along with the associated text.
A new reader may worry about interaction with other code, especially
since mark is not initialized to zero in handle_node() itself.
Disperse such worries by making it local. No functional change
intended.

Since the dumpfile version 1 days, the Subversion dump format
gained some new fields:
- a unique identifier for the repository (version 2 format)
- whether the text and properties for a node should be
interpreted as deltas
- checksums for a delta's preimage
- SHA-1 sums as alternatives to the existing MD5 checksums for
copy source and the payload (delta).
For now what is relevant to us is the Text-delta and Prop-delta
fields, since not noticing these causes a dump file to be
misinterpreted (see the previous commit).

Running git-merge on an unborn branch is supposed to do an index-level
merge with the other side, and then update the branch name there. In
the common case where the index was empty at the start, this makes
'git pull otherrepo branch' a convenient way to populate the history
after 'git init'.
However, if the index was *not* empty, git-merge silently discards
*both index and worktree* copies of all files that were tracked,
leading to data loss. Exhibit this bug.
