In "git log --decorate", you would see the commit header like this:
commit ... (HEAD, jc/decorate-leaky-separator-color)
where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.
If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say
[color "decorate"]
head = black
branch = black
because that you would not be able to reuse same configuration on a
white-on-black terminal. You would naively expect
[color "decorate"]
head = normal
branch = normal
to work, but unfortunately it does not. It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements. This is because the code
forgets to reset the color after printing the "prefix" in its own
color.
It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

A line can be continued via a backquote-LF and can be chomped at a
comment character. But that is not specific to string-typed values.
It is common to all, just like unquoted leading and trailing
whitespaces are stripped and inter-word spacing are retained.
Move the description around and desribe these structural rules
first, then introduce the double-quote facility as a way to override
them, and finally mention various types of values.
Note that these structural rules only apply to the value part of the
configuration file. E.g.
[aSection] \
name \
= value
does not work, because the rules kick in only after seeing "name =".

2) The documentation of submodule.$name.update is scattered across three

incorrect, because the code always uses the value from .git/config

The rename code cannot handle an input where we have
duplicate destinations (i.e., more than one diff_filepair in
the queue with the same string in its pair->two->path). We
end up allocating only one slot in the rename_dst mapping.
If we fill in the diff_filepair for that slot, when we
re-queue the results, we may queue that filepair multiple
times. When the diff is finally flushed, the filepair is
processed and free()d multiple times, leading to heap
corruption.
This situation should only happen when a tree diff sees
duplicates in one of the trees (see the added test for a
detailed example). Rather than handle it, the sanest thing
is just to turn off rename detection altogether for the
diff.

This function manages the mapping of destination pathnames
to filepairs, and it handles both insertion and lookup. This
makes the return value a bit confusing, as we return a newly
created entry (even though no caller cares), and have no
room to indicate to the caller that an entry already
existed.
Instead, let's break this up into two distinct functions,
both backed by a common binary search. The binary search

Since b19138b (git-svn: Make it incrementally faster by minimizing temp
files, v1.6.0), git-svn has been using the Git.pm temp_acquire and
temp_release mechanism to avoid unnecessary temp file churn and provide
a speed boost.
However, that change introduced a call to temp_acquire inside the
Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file.
Because an SVN::Pool is active at the time this function is called, if
the Git::temp_acquire function ends up actually creating a new
FileHandle for the temp file (which it will the first time it's called
with the name 'svn_hash') that FileHandle will end up in the SVN::Pool
and should that pool have SVN::Pool::clear called on it that FileHandle
will be closed out from under Git::temp_acquire.
Since the only call site to Git::temp_acquire with the name 'svn_hash'
is inside the close_file function, if an 'svn_hash' temp file is ever
created its FileHandle is guaranteed to be created in the active
SVN::Pool.
This has not been a problem in the past because the SVN::Pool was not
being cleared. However, since dfa72fdb (git-svn: reload RA every
log-window-size, v2.2.0) the pool has been getting cleared periodically
at which point the FileHandle for the 'svn_hash' temp file gets closed.
Any subsequent calls to Git::temp_acquire for 'svn_hash', however,
succeed without creating/opening a new temporary file since it still has
the now invalid FileHandle in its cache. Callers that then attempt to
use that FileHandle fail with an error.
We avoid this problem by making sure the 'svn_hash' temp file is created
in the same place the 'svn_delta_...' and 'git_blob_...' temp files are
(and then temp_release'd) so that it can be safely used inside the
close_file function without having its FileHandle end up in an SVN::Pool
that gets cleared.
Additionally the Git.pm cat_blob function creates a bidirectional pipe
FileHandle using the IPC::Open2::open2 function. If that handle is
created too late, it also gets caught up in the SVN::Pool and incorrectly
closed by the SVN::Pool::clear call. But this only seems to happen with
more recent versions of Perl and svn.
To avoid this problem we add an explicit call to _open_cat_blob_if_needed
before the first call to SVN::Pool->new_default to make sure the open2
handle does not end up in the SVN::Pool.

We have a helper function test_ln_s_add that inserts a symbolic link

There is a small flaw in the emulation path: the added entry does not
pick up stat information of the fake symbolic link from the file system,
as a consequence, the index is not exactly the same as for the "regular"
path (where symbolic links are available). To fix this, just call
git update-index again.

We use the daemon_avoid_alias function to make sure that the
pathname the user gives us is sane. However, after applying
that check, we might then interpolate the path using a
string given by the server admin, but which may contain more
untrusted data from the client. We should be sure to
sanitize this data, as well.
We cannot use daemon_avoid_alias here, as it is more strict
than we need in requiring a leading '/'. At the same time,
we can be much more strict here. We are interpreting a
hostname, which should not contain slashes or excessive runs
of dots, as those things are not allowed in DNS names.
Note that in addition to cleansing the hostname field, we
must check the "canonical hostname" (%CH) as well as the
port (%P), which we take as a raw string. For the canonical
hostname, this comes from an actual DNS lookup on the
accessed IP, which makes it a much less likely vector for
problems. But it does not hurt to sanitize it in the same
way. Unfortunately we cannot test this case easily, as it
would involve a custom hostname lookup.
We do not need to check %IP, as it comes straight from
inet_ntop, so must have a sane form.

Because Git tracks symbolic links as symbolic links, a path that
has a symbolic link in its leading part (e.g. path/to/dir/file,
where path/to/dir is a symbolic link to somewhere else, be it
inside or outside the working tree) can never appear in a patch
that validly applies, unless the same patch first removes the
symbolic link to allow a directory to be created there.
Detect and reject such a patch.
Things to note:
- Unfortunately, we cannot reuse the has_symlink_leading_path()
from dir.c, as that is only about the working tree, but "git
apply" can be told to apply the patch only to the index or to
both the index and to the working tree.
- We cannot directly use has_symlink_leading_path() even when we
are applying only to the working tree, as an early patch of a
valid input may remove a symbolic link path/to/dir and then a
later patch of the input may create a path path/to/dir/file, but
"git apply" first checks the input without touching either the
index or the working tree. The leading symbolic link check must
be done on the interim result we compute in-core (i.e. after the
first patch, there is no path/to/dir symbolic link and it is
perfectly valid to create path/to/dir/file).
Similarly, when an input creates a symbolic link path/to/dir and
then creates a file path/to/dir/file, we need to flag it as an
error without actually creating path/to/dir symbolic link in the
filesystem.
Instead, for any patch in the input that leaves a path (i.e. a non
deletion) in the result, we check all leading paths against the
resulting tree that the patch would create by inspecting all the
patches in the input and then the target of patch application
(either the index or the working tree).
This way, we catch a mischief or a mistake to add a symbolic link
path/to/dir and a file path/to/dir/file at the same time, while
allowing a valid patch that removes a symbolic link path/to/dir and
then adds a file path/to/dir/file.

We should reject a patch, whether it renames/copies dir/file to

We currently read the preimage to apply a patch from the index only
when the --cached option is given. Do so also when the command is
running under the --index option. With --index, the index entry and
the working tree file for a path that is involved in a patch must be
identical, so this should not affect the result, but by reading from
the index, we will get the protection to avoid reading an unintended
path beyond a symbolic link automatically.

By default, a patch that affects outside the working area (either a
Git controlled working tree, or the current working directory when
"git apply" is used as a replacement of GNU patch) is rejected as a
mistake (or a mischief). Git itself does not create such a patch,
unless the user bends over backwards and specifies a non-standard
prefix to "git diff" and friends.
When `git apply` is used as a "better GNU patch", the user can pass
the `--unsafe-paths` option to override this safety check. This
option has no effect when `--index` or `--cached` is in use.
The new test was stolen from Jeff King with slight enhancements.
Note that a few new tests for touching outside the working area by
following a symbolic link are still expected to fail at this step,
but will be fixed in later steps.

When an import has finished, we run end_packfile() to
finalize the data and move the packfile into place. If this
process fails, we call die() and end up in our die_nicely()
handler. Which unfortunately includes running end_packfile
to save any progress we made. We enter the function again,
and start operating on the pack_data struct while it is in
an inconsistent state, leading to a segfault.
One way to trigger this is to simply start two identical
fast-imports at the same time. They will both create the
same packfiles, which will then try to create identically
named ".keep" files. One will win the race, and the other
will die(), and end up with the segfault.
Since 3c078b9, we already reset the pack_data pointer to
NULL at the end of end_packfile. That covers the case of us
calling die() right after end_packfile, before we have
reinitialized the pack_data pointer. This new problem is
quite similar, except that we are worried about calling
die() _during_ end_packfile, not right after. Ideally we
would simply set pack_data to NULL as soon as we enter the
function, and operate on a copy of the pointer.
Unfortunately, it is not so easy. pack_data is a global, and
end_packfile calls into other functions which operate on the
global directly. We would have to teach each of these to
take an argument, and there is no guarantee that we would
catch all of the spots.
Instead, we can simply use a static flag to avoid
recursively entering the function. This is a little less
elegant, but it's short and fool-proof.

Our config code simulates a stdio stream around a buffer,
but our fake ungetc() does not behave quite like the real
one. In particular, we only rewind the position by one
character, but do _not_ actually put the character from the
caller into position.
It turns out that this does not matter, because we only ever
push back the character we just read. In other words, such
an assignment would be a noop. But because the function is
called ungetc, and because it takes a character parameter,
it is a mistake waiting to happen.
Actually assigning the character into the buffer would be
ideal, but our pointer is actually a "const" copy of the
buffer. We do not know who the real owner of the buffer is
in this code, and would not want to munge their contents.
Instead, we can simply add an assertion that matches what
the current caller does, and will let us know if new callers
are added that violate the contract.

The decimal_width function originally appeared in blame.c as
"lineno_width", and was designed for calculating the
print-width of small-ish integer values (line numbers in
text files). In ec7ff5b, it was made into a reusable
function, and in dc801e7, we started using it to align
diffstats.
Binary files in a diffstat show byte counts rather than line
numbers, meaning they can be quite large (e.g., consider
adding or removing a 2GB file). decimal_width is not up to
the challenge for two reasons:
1. It takes the value as an "int", whereas large files may
easily surpass this. The value may be truncated, in
which case we will produce an incorrect value.
2. It counts "up" by repeatedly multiplying another
integer by 10 until it surpasses the value. This can
cause an infinite loop when the value is close to the
largest representable integer.
For example, consider using a 32-bit signed integer,
and a value of 2,140,000,000 (just shy of 2^31-1).
We will count up and eventually see that 1,000,000,000
is smaller than our value. The next step would be to
multiply by 10 and see that 10,000,000,000 is too
large, ending the loop. But we can't represent that
value, and we have signed overflow.
This is technically undefined behavior, but a common
behavior is to lose the high bits, in which case our
iterator will certainly be less than the number. So
we'll keep multiplying, overflow again, and so on.
This patch changes the argument to a uintmax_t (the same
type we use to store the diffstat information for binary
filese), and counts "down" by repeatedly dividing our value
by 10.

When we are parsing a config value, if we see a carriage
return, we fgetc the next character to see if it is a
line feed (in which case we silently drop the CR). If it
isn't, we then ungetc the character, and take the literal
CR.
But we never check whether we in fact got a character at
all. If the config file ends in CR, we will get EOF here,
and try to ungetc EOF. This works OK for a real stdio
stream. The ungetc returns an error, and the next fgetc will
then return EOF again.
However, our custom buffer-based stream is not so fortunate.
It happily rewinds the position of the stream by one
character, ignoring the fact that we fed it EOF. The next
fgetc call returns the final CR again, over and over, and we
end up in an infinite loop.

It seems to be a common mistake to try using a single remote
(e.g. 'origin') to fetch from one place (i.e. upstream) while
pushing to another (i.e. your publishing point).
That will never work satisfactorily, and it is easy to understand
why if you think about what refs/remotes/origin/* would mean in such
a world. It fundamentally cannot reflect the reality. If it
follows the state of your upstream, it cannot match what you have
published, and vice versa.
It may be that misinformation is spread by some people. Let's
counter them by adding a few words to our documentation.
- The description was referring to <oldurl> and <newurl>, but never
mentioned <name> argument you give from the command line. By
mentioning "remote <name>", stress the fact that it is configuring
a single remote.
- Add a reminder that explicitly states that this is about a single
remote, which the triangular workflow is not about.

Since 1e3eefb (tests: replace binary GPG keyrings with
ASCII-armored keys, 2014-12-12), we import our test GPG keys
from a single file. Each keypair in the import stream
contains both the secret and public keys. However, older
versions of gpg reportedly fail to import the public half of
the key. We can solve this by including duplicates of the
public keys separately. The duplicates are ignored by modern
gpg, and this makes older versions work.

b6d8f309 (diff-raw format update take #2., 2005-05-23) started

(9) status, followed by similarlity index number only for C and R.
(10) a tab or a NUL when '-z' option is used.

because C and R _were_ the only ones that came with a number back
then. This was corrected by ddafa7e9 (diff-helper: Fix R/C score

instead of "similarlity index" (because we can have other kind of

an ever evolving system). Later f345b0a0 (Add -B flag to diff-*

Once upon a time, dumb http always fetched .idx files
directly into their final location, and then checked their
validity with parse_pack_index. This was refactored in
commit 750ef42 (http-fetch: Use temporary files for
pack-*.idx until verified, 2010-04-19), which uses the
following logic:
1. If we have the idx already in place, see if it's
valid (using parse_pack_index). If so, use it.
2. Otherwise, fetch the .idx to a tempfile, check
that, and if so move it into place.
3. Either way, fetch the pack itself if necessary.
However, it got step 1 wrong. We pass a NULL path parameter
to parse_pack_index, so an existing .idx file always looks
broken. Worse, we do not treat this broken .idx as an
opportunity to re-fetch, but instead return an error,
ignoring the pack entirely. This can lead to a dumb-http
fetch failing to retrieve the necessary objects.
This doesn't come up much in practice, because it must be a
packfile that we found out about (and whose .idx we stored)
during an earlier dumb-http fetch, but whose packfile we
_didn't_ fetch. I.e., we did a partial clone of a
repository, didn't need some packfiles, and now a followup
fetch needs them.

The list_and_choose() helper is given a prompt and a list, asks the
user to make selection from the list, and then returns a list of
items chosen. Even when it is given an empty list as the original
candidate set to choose from, it gave a prompt to the user, who can
only say "I am done choosing".
Return an empty result when the input is an empty list without
bothering the user. The existing caller must already have a logic
to say "Nothing to do" or an equivalent when the returned list is
empty (i.e. the user chose to select nothing) if it is necessary, so
no change to the callers is necessary.
This fixes the case where "add untracked" is asked in "git add -i"

Under --whitespace=fix option, match_fragment() function examines
the preimage (the common context and the removed lines in the patch)
and the file being patched and checks if they match after correcting
all whitespace errors. When they are found to match, the common
context lines in the preimage is replaced with the fixed copy,
because these lines will then be copied to the corresponding place
in the postimage by a later call to update_pre_post_images(). Lines
that are added in the postimage, under --whitespace=fix, have their
whitespace errors already fixed when apply_one_fragment() prepares
the preimage and the postimage, so in the end, application of the
patch can be done by replacing the block of text in the file being
patched that matched the preimage with what is in the postimage that
was updated by update_pre_post_images().
In the earlier days, fixing whitespace errors always resulted in
reduction of size, either collapsing runs of spaces in the indent to
a tab or removing the trailing whitespaces. These days, however,
some whitespace error fix results in extending the size.
250b3c6c (apply --whitespace=fix: avoid running over the postimage
buffer, 2013-03-22) tried to compute the final postimage size but
its math was flawed. It counted the size of the block of text in
the original being patched after fixing the whitespace errors on its
lines that correspond to the preimage. That number does not have
much to do with how big the final postimage would be.
Instead count (1) the added lines in the postimage, whose size is
the same as in the final patch result because their whitespace
errors have already been corrected, and (2) the fixed size of the
lines that are common.

"git apply --whitespace=fix" used to be able to assume that fixing

beginning of lines. An update to accomodate fixes that lengthens
the result by e.g. expanding leading tabs into spaces were made long
time ago but the logic miscounted the necessary space after such
whitespace fixes, leading to either under-allocation or over-usage
of already allocated space.

A typical remote helper will return a `list` of refs containing a symbolic
ref HEAD, pointing to, e.g. refs/heads/master. In the case of a clone, all
the refs are being requested through `fetch` or `import`, including the
symbolic ref.
While this works properly, in some cases of a fetch, like `git fetch url`
or `git fetch origin HEAD`, or any fetch command involving a symbolic ref
without also fetching the corresponding ref it points to, the fetch command
fails with:
fatal: bad object 0000000000000000000000000000000000000000
error: <remote> did not send all necessary objects
(in the case the remote helper returned '?' values to the `list` command).
This is because there is only one ref given to fetch(), and it's not
further resolved to something at the end of fetch_with_import().
While this can be somehow handled in the remote helper itself, by adding
a refspec for the symbolic ref, and storing an explicit ref in a private
namespace, and then handling the `import` for that symbolic ref
specifically, very few existing remote helpers are actually doing that.
So, instead of requesting the exact list of wanted refs to remote helpers,
treat symbolic refs differently and request the ref they point to instead.
Then, resolve the symbolic refs values based on the pointed ref.
This assumes there is no more than one level of indirection (a symbolic
ref doesn't point to another symbolic ref).

POSIXPERM requires that a later call to stat(2) (hence "ls -l")
faithfully reproduces what an earlier chmod(2) did. Some
filesystems cannot satisify this.
SANITY requires that a file or a directory is indeed accessible (or
inaccessible) when its permission bits would say it ought to be
accessible (or inaccessible). Running tests as root would lose this
prerequisite for obvious reasons.
Fix a few tests that misuse POSIXPERM.
t0061-run-command.sh has two uses of POSIXPERM.
- One checks that an attempt to execute a file that is marked as
unexecutable results in a failure with EACCES; I do not think
having root-ness or any other capability that busts the
filesystem permission mode bits will make you run an unexecutable
file, so this should be left as-is. The test does not have
anything to do with SANITY.
- The other one expects 'git nitfol' runs the alias when an
alias.nitfol is defined and a directory on the PATH is marked as
unreadable and unsearchable. I _think_ the test tries to reject
the alternative expectation that we want to refuse to run the
alias because it would break "no alias may mask a command" rule
if a file 'git-nitfol' exists in the unreadable directory but we
cannot even determine if that is the case. Under !SANITY that
busts the permission bits, this test no longer checks that, so it
must be protected with SANITY.
t1509-root-worktree.sh expects to be run on a / that is writable by
the user and sees if Git behaves "sensibly" when /.git is the
repository to govern a worktree that is the whole filesystem, and
also if Git behaves "sensibly" when / itself is a bare repository
with refs, objects, and friends (I find the definition of "behaves
sensibly" under these conditions hard to fathom, but it is a
different matter).
The implementation of the test is very much problematic.
- It requires POSIXPERM, but it does not do chmod or checks modes
in any way.
- It runs "rm /*" and "rm -fr /refs /objects ..." in one of the
tests, and also does "cd / && git init --bare". If done on a
live system that takes advantages of the "feature" being tested,
these obviously will clobber the system. But there is no guard
against such a breakage.
- It uses "test $UID = 0" to see rootness, which now should be
spelled "! test_have_prereq NOT_ROOT"
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The SANITY prerequisite is really about whether the
filesystem will respect the permissions we set, and being
root is only one part of that. But the httpd tests really
just care about not being root, as they are trying to avoid
weirdness in apache (see a1a3011 for details).
Let's switch out SANITY for a new NOT_ROOT prerequisite,
which will let us tweak SANITY more freely.
We implement NOT_ROOT by checking `id -u`, which is in POSIX
and seems to be available even on MSYS. Note that we cannot
just call this "ROOT" and ask for "!ROOT". The possible
outcomes are:
1. we know we are root
2. we know we are not root
3. we could not tell, because `id` was not available
We should conservatively treat (3) as "does not have the
prerequisite", which means that a naive negation would not
work.

For some unknown reason, the dd on my Windows box segfaults randomly,
but since recently, it does so much more often than it used to, which
makes running the test suite burdensome.
Use printf to write large files instead of dd. To emphasize that three
of the large blobs are exact copies, use cp to allocate them.
The new code makes the files a bit smaller, and they are not sparse
anymore, but the tests do not depend on these properties. We do not want
to use test-genrandom here (which is used to generate large files
elsewhere in t1050), so that the files can be compressed well (which
keeps the run-time short).
The files are now large text files, not binary files. But since they
are larger than core.bigfilethreshold they are diagnosed as binary
by Git. For this reason, the 'git diff' tests that check the output
for "Binary files differ" still pass.

The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().
While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as
[behind -111794512]
[ahead 38881640, behind 5103867]

- "exec_cmd.h" became unnecessary at b931aa5a (Call builtin ls-tree
in git-cat-file -p, 2006-05-26), when it changed an earlier code
that delegated tree display to "ls-tree" via the run_command()
API (hence needing "exec_cmd.h") to call cmd_ls_tree() directly.
We should have removed the include in the same commit, but we
forgot to do so.
- "diff.h" was added at e5fba602 (textconv: support for cat_file,
2010-06-15), together with "userdiff.h", but "userdiff.h" can be
included without including "diff.h"; the header was unnecessary
from the beginning.
- "tag.h" and "tree.h" were necessary since 8e440259 (Use blob_,
commit_, tag_, and tree_type throughout., 2006-04-02) to check
the type of object by comparing typename with tree_type and
tag_type (pointers to extern strings).
21666f1a (convert object type handling from a string to a number,
2007-02-26) made these <type>_type strings unnecessary, and it
could have switched to include "object.h", which is necessary to
use typename(), but it forgot to do so. Because "tag.h" and
"tree.h" include "object.h", it did not need to explicitly
include "object.h" in order to start using typename() itself.
We do not even have to include "object.h" after removing these
two #includes, because "builtin.h" includes "commit.h" which in
turn includes "object.h" these days. This happened at 7b9c0a69
(git-commit-tree: make it usable from other builtins,

Apache servers using mod_auth_kerb can be configured to allow the user
to authenticate either using Negotiate (using the Kerberos ticket) or
Basic authentication (using the Kerberos password). Often, one will
want to use Negotiate authentication if it is available, but fall back
to Basic authentication if the ticket is missing or expired.
However, libcurl will try very hard to use something other than Basic
auth, even over HTTPS. If Basic and something else are offered, libcurl
will never attempt to use Basic, even if the other option fails.
Teach the HTTP client code to stop trying authentication mechanisms that
don't use a password (currently Negotiate) after the first failure,
since if they failed the first time, they will never succeed.

If ncurses needs ~/.terminfo for the current $TERM, then tput will
succeed before changing HOME to $TRASH_DIRECTORY but fail afterward.
Move the tests that determine whether there is color support after
changing HOME so that color=t is set if and only if tput would succeed
when say_color() is run.
Note that color=t is now set after --no-color is processed, so the
condition to set color=t has changed: it is now set only if
color has not already been set to the empty string by --no-color.
This disables color support for those that need ~/.terminfo for
their TERM, but it's better than filling the screen with:
tput: unknown terminal "custom-terminal-name-here"
An alternative would be to symlink or copy the user's terminfo
database into $TRASH_DIRECTORY, but this is tricky due to the lack of
a standard name for the terminfo database (for example, instead of a
~/.terminfo directory, NetBSD uses a ~/.terminfo.cdb database file).

Prior to d38379e (make update-server-info more robust, 2014-09-13),
we used a straight "fopen" to create the info/refs and
objects/info/packs files, which creates the file using mode 0666
(less the default umask).
In d38379e, we switched to creating the file with mkstemp to get a
unique filename. But mkstemp also uses the more restrictive 0600
mode to create the file. This was an unintended side effect that we
did not want, and causes problems when the repository is served by a
different user than the one running update-server-info (it is not
readable by a dumb http server running as `www`, for example).
We can fix this by using git_mkstemp_mode and specifying 0666 to
make sure that the umask is honored.
Note that we could also say "just use core.sharedrepository", as we
do call adjust_shared_perm on the result before renaming it into
place. But that should not be necessary as long as everybody
involved is using permissive umask to allow HTTP server to read
necessary files.

According to the cURL documentation for the CURLOPT_USE_SSL option,
it is only used with plain text protocols that get upgraded to SSL
using the STARTTLS command.
The server.use_ssl variable is only set when we are using a protocol
that is already SSL/TLS (i.e. imaps), so setting CURLOPT_USE_SSL
when the server.use_ssl variable is set has no effect whatsoever.
Instead, set CURLOPT_USE_SSL to CURLUSESSL_TRY when the server.use_ssl
variable is NOT set so that cURL will attempt to upgrade the plain
text connection to SSL/TLS using STARTTLS in that case.
This much more closely matches the behavior of the non-cURL code path.

The parse_options API expects an array of alternative usage lines
to which it automatically ads the language-appropriate "or" when
displaying. Each of these options is marked for translation with N_
and then later translated when gettext is called on each element
of the array.
Since the N_ macro just expands to its argument, if two N_-marked
strings appear next to each other without being separated by anything
else such as a comma, the preprocessor will join them into one string.
In that case two separate strings get marked for translation, but at
runtime they have been joined into a single string passed to gettext
which then fails to get translated because the combined string was
never marked for translation.
Fix this by properly separating the two N_ marked strings with
a comma and removing the embedded "\n" and " or:" that are
properly supplied by the parse_options API.

Our is_hfs_dotgit function relies on the hackily-implemented
next_hfs_char to give us the next character that an HFS+
filename comparison would look at. It's hacky because it
doesn't implement the full case-folding table of HFS+; it
gives us just enough to see if the path matches ".git".
At the end of next_hfs_char, we use tolower() to convert our
32-bit code point to lowercase. Our tolower() implementation
only takes an 8-bit char, though; it throws away the upper
24 bits. This means we can't have any false negatives for
is_hfs_dotgit. We only care about matching 7-bit ASCII
characters in ".git", and we will correctly process 'G' or
'g'.
However, we _can_ have false positives. Because we throw
away the upper bits, code point \u{0147} (for example) will
look like 'G' and get downcased to 'g'. It's not known
whether a sequence of code points whose truncation ends up
as ".git" is meaningful in any language, but it does not
hurt to be more accurate here. We can just pass out the full
32-bit code point, and compare it manually to the upper and
lowercase characters we care about.

When running for example "git bisect bad HEAD" or

commit hash before checking if it is the expected

We could do that in is_expected_rev() or in
check_expected_revs(), but it is already done in
bisect_state(). Let's just store the hash values
that result from this parsing, and then reuse

checkout-index --temp only properly prints relative paths which are
descendants of the current directory. Paths in ancestor or sibling
directories (or their children) are often printed in mangled form. For
example:
mkdir a bbb &&
>file &&
>bbb/file &&
git update-index --add file bbb/file &&
cd a &&
git checkout-index --temp ../file ../bbb/file
prints:
.merge_file_ooblek le
.merge_file_igloo0 b/file
rather than the correct:
.merge_file_ooblek ../file
.merge_file_igloo0 ../bbb/file
Internally, given the above example, checkout-index prefixes each input
argument with the name of the current directory ("a/", in this case),
and then assumes that it can simply skip forward by strlen("a/") bytes
to recover the original name. This works for files in the current
directory or its descendants, but fails for files in ancestors or
siblings (or their children) due to path normalization.
For instance, given "../file", "a/" is prepended, giving "a/../file".
Path normalization folds out "a/../", resulting in "file". Attempting
to recover the original name by skipping strlen("a/") bytes gives the
incorrect "le" rather than the desired "../file".
Fix this by taking advantage of write_name_quoted_relative() to recover
the original name properly, rather than assuming that it can be
recovered by skipping strlen(prefix) bytes.
As a bonus, this also fixes a bug in which checkout-index --temp
accessed and printed memory beyond the end-of-string. For instance,
within a subdirectory named "subdirectory", and given argument
"../file", prefixing would give "subdirectory/../file", which would
become "file" after normalization. checkout-index would then attempt to
recover the original name by skipping strlen("subdirectory/") bytes of
"file", which placed it well beyond end-of-string. Despite this error,
it often appeared to give the correct result, but only due to an
accident of implementation which left an apparently correct copy of the
path in memory following the normalized value. In particular, handed
"subdirectory/../file", in-place processing by normalize_path_copy_len()
resulted in "file\0rectory/../file". When checkout-index skipped
strlen("subdirectory/") bytes, it ended up back at "../file" and thus
appeared to give the correct answer, despite being past end-of-string.

sometimes _appearing_ to be printed correctly, but this is an accident
of implementation in which a "correct" copy of the string exists in
memory beyond the end of the real string, and that "correct" copy gets
printed. This test takes care to avoid the accidentally "correct"
behavior by testing with a filename longer than the directory name in

When fetching into or pushing from a shallow repository, we want to

Teach pack-objects a --shallow option to indicate that we're pushing
from or fetching into a shallow repository. Use

Unfortunately, they cause a significant performance regression when
pushing non-shallow clones with lots of refs (23.322 seconds vs.
4.785 seconds with 22400 refs). Add an option to git rev-list,

The sample hook explicitly sets IFS to SP and nothing else so that
the "read" used in the per-ref while loop that iterates over
"<localref> SP <localsha1> SP <remoteref> SP <remotesha>" records,
where we know refs and sha1s will not have SPs, would split them
correctly.
While this is not wrong per-se, it is not necessary; because we know
these fields do not contain HT or LF, either, we can simply leave
IFS the default.
This will also prevent those who cut and paste from this sample from
getting bitten when they write things in the per-ref loop that need
splitting with the default $IFS (e.g. use $(git rev-list ...) to
produce one-record-per-line output).

With the release of Mac OS X 10.7 in July 2011, Apple deprecated all
openssl.h functionality due to OpenSSL ABI (application binary
interface) instability, resulting in an explosion of compilation
warnings about deprecated SSL, SHA1, and X509 functions (among others).
61067954ce (cache.h: eliminate SHA-1 deprecation warnings on Mac OS X;
2013-05-19) and be4c828b76 (imap-send: eliminate HMAC deprecation
warnings on Mac OS X; 2013-05-19) attempted to ameliorate the situation
by taking advantage of drop-in replacement functionality provided by
Apple's (ABI-stable) CommonCrypto facility, however CommonCrypto
supplies only a subset of deprecated OpenSSL functionality, thus a host
of warnings remain.
Despite this shortcoming, it was hoped that Apple would ultimately
provide CommonCrypto replacements for all deprecated OpenSSL
functionality, and that the effort started by 61067954ce and be4c828b76
would be continued and eventually eliminate all deprecation warnings.
However, now 3.5 years later, and with Mac OS X at 10.10, the hoped-for
CommonCrypto replacements have not yet materialized, nor is there any
indication that they will be forthcoming.
These Apple-specific warnings are pure noise: they don't tell us
anything useful and we have no control over them, nor is Apple likely to
provide replacements any time soon. Such noise may obscure other
legitimate warnings, therefore silence them.

Now that the index can block pathnames that can be mistaken
to mean ".git" on NTFS and FAT32, it would be helpful for
fsck to notice such problematic paths. This lets servers
which use receive.fsckObjects block them before the damage
spreads.
Note that the fsck check is always on, even for systems
without core.protectNTFS set. This is technically more
restrictive than we need to be, as a set of users on ext4
could happily use these odd filenames without caring about
NTFS.
However, on balance, it's helpful for all servers to block
these (because the paths can be used for mischief, and
servers which bother to fsck would want to stop the spread
whether they are on NTFS themselves or not), and hardly
anybody will be affected (because the blocked names are
variants of .git or git~1, meaning mischief is almost
certainly what the tree author had in mind).
Ideally these would be controlled by a separate
"fsck.protectNTFS" flag. However, it would be much nicer to
be able to enable/disable _any_ fsck flag individually, and
any scheme we choose should match such a system. Given the
likelihood of anybody using such a path in practice, it is
not unreasonable to wait until such a system materializes.

The point of disallowing ".git" in the index is that we
would never want to accidentally overwrite files in the
repository directory. But this means we need to respect the
filesystem's idea of when two paths are equal. The prior
commit added a helper to make such a comparison for NTFS
and FAT32; let's use it in verify_path().
We make this check optional for two reasons:
1. It restricts the set of allowable filenames, which is
unnecessary for people who are not on NTFS nor FAT32.
In practice this probably doesn't matter, though, as
the restricted names are rather obscure and almost
certainly would never come up in practice.
2. It has a minor performance penalty for every path we
insert into the index.
This patch ties the check to the core.protectNTFS config
option. Though this is expected to be most useful on Windows,
we allow it to be set everywhere, as NTFS may be mounted on
other platforms. The variable does default to on for Windows,
though.

We do not allow paths with a ".git" component to be added to
the index, as that would mean repository contents could
overwrite our repository files. However, asking "is this
path the same as .git" is not as simple as strcmp() on some
filesystems.
On NTFS (and FAT32), there exist so-called "short names" for
backwards-compatibility: 8.3 compliant names that refer to the same files
as their long names. As ".git" is not an 8.3 compliant name, a short name
is generated automatically, typically "git~1".
Depending on the Windows version, any combination of trailing spaces and
periods are ignored, too, so that both "git~1." and ".git." still refer
to the Git directory. The reason is that 8.3 stores file names shorter
than 8 characters with trailing spaces. So literally, it does not matter
for the short name whether it is padded with spaces or whether it is
shorter than 8 characters, it is considered to be the exact same.
The period is the separator between file name and file extension, and
again, an empty extension consists just of spaces in 8.3 format. So
technically, we would need only take care of the equivalent of this
regex:
(\.git {0,4}|git~1 {0,3})\. {0,3}
However, there are indications that at least some Windows versions might
be more lenient and accept arbitrary combinations of trailing spaces and
periods and strip them out. So we're playing it real safe here. Besides,
there can be little doubt about the intention behind using file names
matching even the more lenient pattern specified above, therefore we
should be fine with disallowing such patterns.
Extra care is taken to catch names such as '.\\.git\\booh' because the
backslash is marked as a directory separator only on Windows, and we want
to use this new helper function also in fsck on other platforms.
A big thank you goes to Ed Thomson and an unnamed Microsoft engineer for
the detailed analysis performed to come up with the corresponding fixes
for libgit2.
This commit adds a function to detect whether a given file name can refer

filesystems.
HFS+'s case-folding does more than just fold uppercase into
lowercase (which we already handle with strcasecmp). It may
also skip past certain "ignored" Unicode code points, so
that (for example) ".gi\u200ct" is mapped ot ".git".
The full list of folds can be found in the tables at:

Implementing a full "is this path the same as that path"
comparison would require us importing the whole set of
tables. However, what we want to do is much simpler: we
only care about checking ".git". We know that 'G' is the

The main hunk loop for add--interactive will loop if it does
not get a known input. This is a good thing if the user
typed some invalid input. However, if we have an
uncorrectable read error, we'll end up looping infinitely.
We can fix this by noticing read errors (i.e., <STDIN>
returns undef) and breaking out of the loop.
One easy way to trigger this is if you have an editor that
does not take over the terminal (e.g., one that spawns a
window in an existing process and waits), start the editor
with the hunk-edit command, and hit ^C to send SIGINT. The
editor process dies due to SIGINT, but the perl
add--interactive process does not (perl suspends SIGINT for
the duration of our system() call).
We return to the main loop, but further reads from stdin
don't work. The SIGINT _also_ killed our parent git process,
which orphans our process group, meaning that further reads
from the terminal will always fail. We loop infinitely,
getting EIO on each read.
Note that there are several other spots where we read from
stdin, too. However, in each of those cases, we do something
sane when the read returns undef (breaking out of the loop,
taking the input as "no", etc). They don't need similar
treatment.

To figure out the author ident for a commit, we call

from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then

go into a commit.
Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field). If this parsing or validation fails, we skip
updating the environment variables.
This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).
If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.
Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.
When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational. Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.
We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).
In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.
We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

When git is compiled with "-fsanitize=address" (using clang
or gcc >= 4.8), all invocations of git will check for buffer
overflows. This is similar to running with valgrind, except
that it is more thorough (because of the compiler support,
function-local buffers can be checked, too) and runs much
faster (making it much less painful to run the whole test
suite with the checks turned on).
Unlike valgrind, the magic happens at compile-time, so we
don't need the same infrastructure in the test suite that we
did to support --valgrind. But there are two things we can
help with:
1. On some platforms, the leak-detector is on by default,
and causes every invocation of "git init" (and thus
every test script) to fail. Since running git with
the leak detector is pointless, let's shut it off
automatically in the tests, unless the user has already
configured it.
2. When apache runs a CGI, it clears the environment of
unknown variables. This means that the $ASAN_OPTIONS
config doesn't make it to git-http-backend, and it
dies due to the leak detector. Let's mark the variable
as OK for apache to pass.
With these two changes, running
make CC=clang CFLAGS=-fsanitize=address test
works out of the box.

If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.
Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.
So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

When we send out pkt-lines with refnames, we use a static
1000-byte buffer. This means that the maximum size of a ref
over the git protocol is around 950 bytes (the exact size
depends on the protocol line being written, but figure on a sha1
plus some boilerplate).
This is enough for any sane workflow, but occasionally odd
things happen (e.g., a bug may create a ref "foo/foo/foo/..."
accidentally). With the current code, you cannot even use
"push" to delete such a ref from a remote.
Let's switch to using a strbuf, with a hard-limit of
LARGE_PACKET_MAX (which is specified by the protocol). This
matches the size of the readers, as of 74543a0 (pkt-line:
provide a LARGE_PACKET_MAX static buffer, 2013-02-20).
Versions of git older than that will complain about our
large packets, but it's really no worse than the current
behavior. Right now the sender barfs with "impossibly long
line" trying to send the packet, and afterwards the reader
will barf with "protocol error: bad line length %d", which
is arguably better anyway.
Note that we're not really _solving_ the problem here, but
just bumping the limits. In theory, the length of a ref is
unbounded, and pkt-line can only represent sizes up to
65531 bytes. So we are just bumping the limit, not removing
it. But hopefully 64K should be enough for anyone.
As a bonus, by using a strbuf for the formatting we can
eliminate an unnecessary copy in format_buf_write.

Current code uses a fixed PATH_MAX-sized buffer for reading
packed-refs lines. This is a reasonable guess, in the sense
that git generally cannot work with refs larger than
PATH_MAX. However, there are a few cases where it is not
great:
1. Some systems may have a low value of PATH_MAX, but can
actually handle larger paths in practice. Fixing this
code path probably isn't enough to make them work
completely with long refs, but it is a step in the
right direction.
2. We use fgets, which will happily give us half a line on
the first read, and then the rest of the line on the
second. This is probably OK in practice, because our
refline parser is careful enough to look for the
trailing newline on the first line. The second line may
look like a peeled line to us, but since "^" is illegal
in refnames, it is not likely to come up.
Still, it does not hurt to be more careful.

When we detect an invalid tag-name header in a tag object,
like, "tag foo bar\n", we feed the pointer starting at "foo
bar" to a printf "%s" formatter. This shows the name, as we
want, but then it keeps printing the rest of the tag buffer,
rather than stopping at the end of the line.
Our tests did not notice because they look only for the
matching line, but the bug is that we print much more than
we wanted to. So we also adjust the test to be more exact.
Note that when fscking tags with "index-pack --strict", this
is even worse. index-pack does not add a trailing
NUL-terminator after the object, so we may actually read
past the buffer and print uninitialized memory. Running
t5302 with valgrind does notice the bug for that reason.

When we read a reflog file in reverse, we read whole chunks
of BUFSIZ bytes, then loop over the buffer, parsing any
lines we find. We find the beginning of each line by looking
for the newline from the previous line. If we don't find
one, we know that we are either at the beginning of
the file, or that we have to read another block.
In the latter case, we stuff away what we have into a
strbuf, read another block, and continue our parse. But we
missed one case here. If we did find a newline, and it is at
the beginning of the block, we must also stuff that newline
into the strbuf, as it belongs to the block we are about to
read.
The minimal fix here would be to add this special case to
the conditional that checks whether we found a newline.
But we can make the flow a little clearer by rearranging a
bit: we first handle lines that we are going to show, and
then at the end of each loop, stuff away any leftovers if
necessary. That lets us fold this special-case in with the
more common "we ended in the middle of a line" case.

stop further prompts.
2. Some helpers may know that prompting cannot possibly

The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.
When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.
And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.
We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only

namely:
- A change only to the working tree but not to the index is still a
change to be protected;
- An untracked file in the working tree that would be overwritten
by a push-to-deploy needs to be protected;
- A change that happens to make a file identical to what is being

copy when the callee returned a new string because they cannot tell
if they should free it.
Change the contract between the callers and system_path() to make
the returned string owned by the callers; they are responsible for
freeing it when done, but they do not have to make their own copy to
store it away.
Adjust the callers to make sure they do not leak the returned string
once they are done, but do not bother freeing it just before dying,
exiting or exec'ing other program to avoid unnecessary churn.

An example where this happens is when doing an ls-tree on a tree that
contains a commit link. In that case, find_unique_abbrev is called
to get a non-abbreviated hex sha1, but still, a lookup is done as
to whether the sha1 is in the repository (which ends up looking for
a loose object in .git/objects), while the result of that lookup is
not used when returning a non-abbreviated hex sha1.

The thread at http://thread.gmane.org/gmane.comp.version-control.git/257392
details problems when applying patches with "git am" in a repository with
CRLF line endings. In the example in the thread, the repository originated
from "git-svn" so it is not possible to use core.eol and friends on it.
Right now, the best option is to use "git am --keep-cr". However, when
a patch create new files, the patch application process will reject the
new file because it finds a "/dev/null\r" string instead of "/dev/null".
The problem is that SMTP transport is CRLF-unsafe. Sending a patch by
email is the same as passing it through "dos2unix | unix2dos". The newly
introduced CRLFs are normally transparent because git-am strips them. The
keepcr=true setting preserves them, but it is mostly working by chance
and it would be very problematic to have a "git am" workflow in a
repository with mixed LF and CRLF line endings.
The MIME solution to this is the quoted-printable transfer enconding.
This is not something that we want to enable by default, since it makes
received emails horrible to look at. However, it is a very good match
for projects that store CRLF line endings in the repository.
The only disadvantage of quoted-printable is that quoted-printable
patches fail to apply if the maintainer uses "git am --keep-cr". This
is because the decoded patch will have two carriage returns at the end
of the line. Therefore, add support for base64 transfer encoding too,
which makes received emails downright impossible to look at outside
a MUA, but really just works.
The patch covers all bases, including users that still live in the late
80s, by also providing a 7bit content transfer encoding that refuses
to send emails with non-ASCII character in them. And finally, "8bit"
will add a Content-Transfer-Encoding header but otherwise do nothing.

In their effort to emulate POSIX as close as possible, the MSYS tools
and Cygwin treat the file name "foo.exe" as "foo" when the latter is
asked for, but not present, but the former is present.
Following this rule, 'cp /bin/sh a/bin' actually copies the file
/bin/sh.exe, so that we now have a/bin/sh.exe in the repository. This
difference did not matter in the tests in the past because we were only
interested in the equality of contents generated in various ways. But
recently added tests check file names, in particular, the presence of
"a/bin/sh". This test fails on Windows, as we do not have a file by this
name, but "a/bin/sh.exe".
Use test-genrandom to generate the large binary file in the repository

b) The user executable bit is always 1, e.g. cifs mounted with
-ofile_mode=0755
c) There are system where user executable bit is 1 even if it
should be 0 like b), but the file mode can be maintained
locally. chmod -x changes the file mode from 0766 to 0666,
until the file system is unmounted and remounted and the file
mode is 0766 again.
This been observed when a Windows machine with NTFS exports a share to

Until now, the highlighting colors were hard-coded in the

to read from color.diff-highlight.* to set them.
In addition, it expands the possiblities considerably by
adding two features:
1. Old/new lines can be colored independently (so you can
use a color scheme that complements existing line
coloring).
2. Normal, unhighlighted parts of the lines can be colored,
too. Technically this can be done by separately
configuring color.diff.old/new and matching it to your

You can turn on ANSI text attributes like "reverse" by
putting "reverse" in your color spec. However, you cannot
ask to turn reverse off.
For common cases, this does not matter. You would turn on
"reverse" at the start of a colored section, and then clear
all attributes with a "reset". However, you may wish to turn
on some attributes, then selectively disable others. For
example:
git log --format="%C(bold ul yellow)%h%C(noul) %s"
underlines just the hash, but without the need to re-specify
the rest of the attributes. This can also help third-party
programs, like contrib/diff-highlight, that want to turn
some attribute on/off without disrupting existing coloring.
Note that some attribute specifications are probably
nonsensical (e.g., "bold nobold"). We do not bother to flag
such constructs, and instead let the terminal sort it out.

When we parse a color name like "red" into its ANSI color
value, we pack the storage into a single int that may take
on many values:
1. If it's "-2", no value has been specified.
2. If it's "-1", the value is "normal" (i.e., no color).
3. If it's 0 through 7, the value is a standard ANSI
color.
4. If it's larger (up to 255), it is a 256-color extended
value.
Given these magic numbers, it is often hard to see what is
going on in the code. Let's refactor this into a struct with
a flag that tells which scheme we are using, along with a
numeric value. This is more verbose, but should hopefully be
simpler to follow. It will also allow us to easily add
support for more schemes, like 24-bit RGB values.
The result is also slightly less efficient to store, but
that's OK; we only store this intermediate state during the
parse, after which we write out the actual ANSI bytes.

Most of git-config's command line options use OPT_BIT to
choose an action, and then parse the non-option arguments
in a context-dependent way. However, --get-color and
--get-colorbool are unlike the rest of the options, in that
they are OPT_STRING, taking the option name as a parameter.
This generally works, because we then use the presence of
those strings to set an action bit anyway. But it does mean
that the option-parser will continue looking for options
even after the key (because it is not a non-option; it is an
argument to an option). And running:
git config --get-color some.key -1
(to use "-1" as the default color spec) will barf, claiming
that "-1" is not an option. Instead, we should treat
--get-color and --get-colorbool as action bits, just like
--add, --get, and all the other actions, and then check that
the non-option arguments we got are sane. This fixes the
weirdness above, and makes those two options like all the
others.
This "fixes" a test in t4026, which checked that feeding
"-2" as a color should fail (it does fail, but prior to this
patch, because parseopt barfed, not because we actually ever
tried to parse the color).
This also catches other errors, like:
git config --get-color some.key black blue
which previously silently ignored "blue" (and now will
complain that you gave too many arguments).
There are some possible regressions, though. We now disallow
these, which currently do what you would expect:
# specifying other options after the action
git config --get-color some.key --file whatever
# using long-arg syntax
git config --get-color=some.key
However, we have never advertised these in the
documentation, and in fact they did not work in some older
versions of git. The behavior was apparently switched as an
accidental side effect of d64ec16 (git config: reorganize to

lock_ref_sha1_basic is inconsistent about when it calls
die() and when it returns NULL to signal an error. This is
annoying to any callers that want to recover from a locking
error.
This seems to be mostly historical accident. It was added in
4bd18c4 (Improve abstraction of ref lock/write.,
2006-05-17), which returned an error in all cases except
calling safe_create_leading_directories, in which case it
died. Later, 40aaae8 (Better error message when we are
unable to lock the index file, 2006-08-12) asked
hold_lock_file_for_update to die for us, leaving the
resolve_ref code-path the only one which returned NULL.
We tried to correct that in 5cc3cef (lock_ref_sha1(): do not
sometimes error() and sometimes die()., 2006-09-30),
by converting all of the die() calls into returns. But we
missed the "die" flag passed to the lock code, leaving us
inconsistent. This state persisted until e5c223e
(lock_ref_sha1_basic(): if locking fails with ENOENT, retry,
2014-01-18). Because of its retry scheme, it does not ask
the lock code to die, but instead manually dies with
unable_to_lock_die().
We can make this consistent with the other return paths by
converting this to use unable_to_lock_message(), and
returning NULL. This is safe to do because all callers
already needed to check the return value of the function,
since it could fail (and return NULL) for other reasons.

As of CGI.pm's 4.08 release, the behavior to call
CGI::param() in a list context is deprecated (because it can
be potentially unsafe if called inside a hash constructor).
This causes gitweb to issue a warning for some of our code,
which in turn causes the tests to fail.
Our use is in fact _not_ one of the dangerous cases, as we
are intentionally using a list context. The recommended
route by 4.08 is to use the new CGI::multi_param() call to
make it explicit that we know what we are doing.
However, that function is only available in 4.08, which is
about a month old; we cannot rely on having it.
One option would be to set $CGI::LIST_CONTEXT_WARN globally,
which turns off the warning. However, that would eliminate
the protection these newer releases are trying to provide.
We want to annotate each site as OK using the new function.
So instead, let's check whether CGI provides the
multi_param() function, and if not, provide an
implementation that just wraps param(). That will work on
both old and new versions of CGI. Sadly, we cannot just
check defined(\&CGI::multi_param), because CGI uses the

According to the Linux open(2) man page, open() must return EISDIR
if a directory was attempted to be opened for writing. Our emulation
in mingw_open() does not get this right: it checks only for O_CREAT.
Fix it to check for a write request.
This fixes a failure in reflog handling, which opens files with
O_APPEND|O_WRONLY, but without O_CREAT, and expects EISDIR when the
named file happens to be a directory.

- write_script
- test_commit
- test_write_lines
- test_line_count
- test_config
- test_unconfig
- test_path_is_missing
- Remove whitespace between redirection operators and their targets.
- Move preparation of "expect" files into tests.
- Rename "output" files to "actual".
- More consistent quoting, especially around commands that might
expand to nothing.
- More visibility of important whitespace with ${indent}.
- Combine pairs of tests that unnecessarily split setup and verification.

When we are parsing approxidate strings and we find three
numbers separate by one of ":/-.", we guess that it may be a
date. We feed the numbers to match_multi_number, which
checks whether it makes sense as a date in various orderings
(e.g., dd/mm/yy or mm/dd/yy, etc).
One of the checks we do is to see whether it is a date more
than 10 days in the future. This was added in 38035cf (date
parsing: be friendlier to our European friends.,
2006-04-05), and lets us guess that if it is currently April
2014, then "10/03/2014" is probably March 10th, not October
3rd.
This has a downside, though; if you want to be overly
generous with your "--until" date specification, we may
wrongly parse "2014-12-01" as "2014-01-12" (because the
latter is an in-the-past date). If the year is a future year
(i.e., both are future dates), it gets even weirder. Due to
the vagaries of approxidate, months _after_ the current date
(no matter the year) get flipped, but ones before do not.
This patch drops the "in the future" check for dates of this
form, letting us treat them always as yyyy-mm-dd, even if
they are in the future. This does not affect the normal
dd/mm/yyyy versus mm/dd/yyyy lookup, because this code path
only kicks in when the first number is greater than 70
(i.e., it must be a year, and cannot be either a date or a
month).
The one possible casualty is that "yyyy-dd-mm" is less
likely to be chosen over "yyyy-mm-dd". That's probably OK,
though because:
1. The difference happens only when the date is in the
future. Already we prefer yyyy-mm-dd for dates in the
past.
2. It's unclear whether anybody even uses yyyy-dd-mm
regularly. It does not appear in lists of common date
formats in Wikipedia[1,2].
3. Even if (2) is wrong, it is better to prefer ISO-like
dates, as that is consistent with what we use elsewhere
in git.

When we "git checkout $tree", we pull paths from $tree into
the index, and then check the resulting entries out to the
worktree. Our method for the first step is rather
heavy-handed, though; it clobbers the entire existing index
entry, even if the content is the same. This means we lose
our stat information, leading checkout_entry to later
rewrite the entire file with identical content.
Instead, let's see if we have the identical entry already in
the index, in which case we leave it in place. That lets
checkout_entry do the right thing. Our tests cover two
interesting cases:
1. We make sure that a file which has no changes is not
rewritten.
2. We make sure that we do update a file that is unchanged
in the index (versus $tree), but has working tree
changes. We keep the old index entry, and
checkout_entry is able to realize that our stat
information is out of date.

The approxidate functions accept an extra "now" parameter to
avoid calling time() themselves. We use this in our test
suite to make sure we have a consistent time for computing
relative dates. However, deep in the bowels of approxidate,
we also call time() to check whether possible dates are far
in the future. Let's make sure that the "now" override makes
it to that spot, too, so we can consistently test that

create_note() has a non-trivial interface, and comprises three loosely
related parts:
1. launching the editor with the note contents, if needed
2. appending to an existing note, if append_only was given
3. adding or removing the resulting note, based on whether it's non-empty
Split it along those lines to make the logic clearer: The first part
goes into a new function - prepare_note_data(), with a simpler interface.
The second part is moved into append_edit(), which is the only user of
this code. Finally, the add vs. remove decision is moved into the callers
(add() and append_edit()), keeping the logic for writing the actual note
object in a separate function: write_note_data().

Use libcurl's high-level API functions to implement git-imap-send
instead of the previous low-level OpenSSL-based functions.
Since version 7.30.0, libcurl's API has been able to communicate with
IMAP servers. Using those high-level functions instead of the current
ones would reduce imap-send.c by some 1200 lines of code. For now,
the old ones are wrapped in #ifdefs, and the new functions are enabled
by make if curl's version is >= 7.34.0, from which version on curl's
CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been
available. The low-level functions will still be used for tunneling
into the server for now.
As I don't have access to that many IMAP servers, I haven't been able to
test the new code with a wide variety of parameter combinations. I did
test both secure and insecure (imaps:// and imap://) connections and
values of "PLAIN" and "LOGIN" for the authMethod.

Locked paths can be saved in a linked list so that if something wrong
happens, *.lock are removed. For relative paths, this works fine if we
keep cwd the same, which is true 99% of time except:
- update-index and read-tree hold the lock on $GIT_DIR/index really
early, then later on may call setup_work_tree() to move cwd.
- Suppose a lock is being held (e.g. by "git add") then somewhere
down the line, somebody calls real_path (e.g. "link_alt_odb_entry"),
which temporarily moves cwd away and back.
During that time when cwd is moved (either permanently or temporarily)
and we decide to die(), attempts to remove relative *.lock will fail,
and the next operation will complain that some files are still locked.
Avoid this case by turning relative paths to absolute before storing
the path in "filename" field.

The callers of get_merge_bases() can choose to leave object flags
used during the merge-base traversal by passing cleanup=0 as a
parameter, but in practice a very few callers can afford to do so
(namely, "git merge-base"), as they need to compute merge base in
preparation for other processing of their own and they need to see
the object without contaminate flags.
Change the function signature of get_merge_bases_many() and
get_merge_bases() to drop the cleanup parameter, so that the
majority of the callers do not have to say ", 1" at the end.
Give a new get_merge_bases_many_dirty() API to support only a few

Just like other hints such as "Changes to be committed" we show in
the editor to remind the committer what paths were involved in the
resulting commit to help improving their log message, this section
is merely a reminder.
Traditionally, it was not made into comments primarily because it
has to be generated outside the wt-status infrastructure, and also
because it was meant as a bit stronger reminder than the others
(i.e. explaining how you resolved conflicts is much more important
than mentioning what you did to every paths involved in the commit).
But that still does not make this hint a part of the log message
proper, and not showing it as a comment is inviting mistakes.
Note that we still notice "Conflicts:" followed by list of indented
pathnames as an old-style cruft and insert a new Signed-off-by:
before it. This is so that "commit --amend -s" adds the new S-o-b
at the right place when used on an older commit.

Extract a helper function from prepare_to_commit() to determine

line and everything below it.
The detection _should_ make sure the "Conflicts:" line it finds is
truly the conflict hint block by checking everything that follows is
a HT indented pathname to avoid false positive, but this logic will

The strbuf_add_commented_lines() function passes a pair of prefixes,
one to be used for a non-empty line, and the other for an empty
line, to underlying add_lines(). The former is set to a comment
char followed by a SP, while the latter is set to just the comment
char. This is designed to give a SP after the comment character,
e.g. "# <user text>\n", on a line with some text, and to avoid
emitting an unsightly "# \n" for an empty line.
Teach this machinery to also use the latter space-less prefix when
the payload line begins with a tab, to show e.g. "#\t<user text>\n";
otherwise we will end up showing "# \t<user text>\n" which is
similarly unsightly.

Starting from a single file, A, if you create B as a copy of A (and
possibly make some edit) and then make extensive change to A, you
will see:
$ git diff -C --name-status
C89 A B
M A
which is expected. However, if you ask the same question in a
different way, you see this:
$ git diff -B -M --name-status
R89 A B
M100 A
telling us that A was rename-edited into B (as if "A will no longer
exist as the result") and at the same time A itself was extensively
edited.
In this case, because the resulting tree still does have file A
(even if it has contents vastly different from the original), we
should use "C"opy, not "R"ename, to avoid hinting that A somehow
goes away.

While use of the --reference option to borrow objects from an
existing local repository of the same project is an effective way to
reduce traffic when cloning a project over the network, it makes the
resulting "borrowing" repository dependent on the "borrowed"
repository. After running
git clone --reference=P $URL Q
the resulting repository Q will be broken if the borrowed repository
P disappears.
The way to allow the borrowed repository to be removed is to repack
the borrowing repository (i.e. run "git repack -a -d" in Q); while
power users may know it very well, it is not easily discoverable.

repacking for the user.

When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.
