18322badc2 fetch: skip on-demand checking when no submodules are configured
It makes no sense to do the - possibly very expensive - call to "rev-list
<new-ref-sha1> --not --all" in check_for_new_submodule_commits() when
there aren't any submodules configured.

Leave check_for_new_submodule_commits() early when no name <-> path
mappings for submodules are found in the configuration. To make that work
reading the configuration had to be moved further up in cmd_fetch(), as
doing that after the actual fetch of the superproject was too late.

This reverts commit ffa69e61d3, reversing
changes made to 4a13c4d148.

Adding a new command line option to receive-pack and feed it from
send-pack is not an acceptable way to add features, as there is no
guarantee that your updated send-pack will be talking to updated
receive-pack. New features need to be added via the capability mechanism
negotiated over the protocol.

9609dc9ddc (short) documentation for the testgit remote helper
While it's not a command meant to be used by actual users (hence, not

The best place for such technical doc is the source code, but users may
not find it without a link in a manpage.

960e311496 Documentation/git-remote-helpers: explain how import works with multiple refs
This is important for two reasons:

* when two "import" lines follow each other, only one "done" command
  should be issued in the fast-import stream, not one per "import".

* The blank line terminating an import command should not be confused
  with the one terminating the sequence of commands.

While we're there, illustrate the corresponding explanation for push
batches with an example.

upstream SVN repository with the given text. The svn:mergeinfo
property may contain commits originating on multiple branches,
separated by newlines.

Cause space characters in the mergeinfo to be replaced by newlines,

Adds a --preserve-empty-dirs flag to the clone operation that will detect
empty directories in the remote Subversion repository and create placeholder
files in the corresponding local Git directories.  This allows "empty"
directories to exist in the history of a Git repository.

Also adds the --placeholder-file flag to control the name of any placeholder
files created.  Default value is ".gitignore".

b4fc8d6ac6 Documentation/remote-helpers: explain capabilities first
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.

8c74ef1e97 strbuf_grow(): maintain nul-termination even for new buffer
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.

688f4f2fbc t4014: "no-add-headers" is actually called "no-add-header"
Since c426003 (format-patch: add --no-cc, --no-to, and
--no-add-headers, 2010-03-07) the tests have checked for an option
called --no-add-headers introduced by letting the user negate
--add-header.

However, the parseopt machinery does not automatically pluralize
anything, so it is in fact called --no-add-header.

Since the option never worked, is not documented anywhere, and
implementing an actual --no-add-headers would lead to silly code
complications, we just adapt the test to the code.

cc663d141a t4014: check for empty files from git format-patch --stdout
Most kinds of failure in 'git format-patch --stdout >output' will
result in an empty 'output'.  This slips past checks that only verify
absence of output, such as the '! grep ...' that are quite prevalent
in t4014.

Introduce a helper check_patch() that checks that at least From, Date
and Subject are present, thus making sure it looks vaguely like a
patch (or cover letter) email.  Then insert calls to it in all tests
that do have positive checks for content.

This makes two of the tests fail.  Mark them as such; they'll be
fixed in a moment.

7732118438 Use memmove in ident_to_git
convert_to_git sets src=dst->buf if any of the preceding conversions
actually did any work.  Thus in ident_to_git we have to use memmove
instead of memcpy as far as src->dst copying is concerned.

f6918da789 t5540-http-test: shorten grep pattern
On OS X, the grep pattern

    "\"OP .*/objects/$x2/X38_X40 HTTP/[.0-9]*\" 20[0-9] "

is too long ($x38 and $x40 represent 38 and 40 copies of [0-9a-f]) for
grep to handle.  In order to still be able to match this, use the sed
invocation to replace what we're looking for with a token.

b6194678b0 Documentation: clarify "git clean -e <pattern>"
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
    parameter) will remove paths A, B, and C, and I want them all removed
    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.

It also fixes small style nit in the parameter to add_exclude() call. The
current code only works because EXC_CMDL happens to be defined as 0.

2f633f41d6 check-ref-format --print: Normalize refnames that start with slashes
When asked if "refs///heads/master" is valid, check-ref-format says "Yes,
it is well formed", and when asked to print canonical form, it shows
"refs/heads/master". This is so that it can be tucked after "$GIT_DIR/"
to form a valid pathname for a loose ref, and we normalize a pathname like
"$GIT_DIR/refs///heads/master" to de-dup the slashes in it.

Similarly, when asked if "/refs/heads/master" is valid, check-ref-format
says "Yes, it is Ok", but the leading slash is not removed when printing,
leading to "$GIT_DIR//refs/heads/master".

Fix it to make sure such leading slashes are removed.  Add tests that such
refnames are accepted and normalized correctly.

11432bb467 git-notes.txt: clarify -C vs. copy and -F
The current description of '-C' together with the analogy to 'git commit
-C' can lead to the wrong conclusion that '-C' copies notes between
objects. Make this clearer by rewording and pointing to 'copy'.

The example for attaching binary notes with 'git hash-object' followed
by 'git notes add -C' immediately raises the question: "Why not use 'git
notes add -F'?". Answer it (the latter is not binary-safe).

fast-import allows to create an annotated tag that annotates a blob,
via mark or direct sha1 specification.

For mark it works, for sha1 it tries to read the object. It tries to
do so via read_sha1_file, and then checks the size to be at least 46.

That's weird, let's just allow to (annotated) tag any object referenced
by sha1. If the object originates from our packfile, we still fail though.

e6baf4a1ae clone: clone from a repository with relative alternates
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.

This updates add_to_alternates_file() to take the path to the alternate
object store, including the "/objects" part at the end (earlier, it was
taking the path to $GIT_DIR and was adding "/objects" itself), as it is
technically possible to specify in objects/info/alternates file the path
of a directory whose name does not end with "/objects".

8ace74c00e git-p4: Allow filtering Perforce branches by user
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

04d277b39e git-p4: Correct branch base depot path detection
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.

55c4a67307 Prevent force-updating of the current branch
"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
but concluded that it was not possible to discern what the user was
actually trying to do.

a7e9c34126 fast-import: treat cat-blob as a delta base hint for next blob
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.

94c3b48247 fast-import: count and report # of calls to diff_delta in stats
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.

d2b17b3220 push: Don't push a repository with unpushed submodules
When working with submodules it is easy to forget to push a
submodule to the server but pushing a super-project that
contains a commit for that submodule. The result is that the
superproject points at a submodule commit that is not available
on the server.

This adds the option --recurse-submodules=check to push. When
using this option git will check that all submodule commits that
are about to be pushed are present on a remote of the submodule.

25e5e2bf85 combine-diff: support format_callback
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.

is fixed because we consider patterns containing NULs as fixed strings
(regcomp cannot accept patterns with NULs).

c9bfb95348 want_color: automatically fallback to color.ui
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.

3e1dd17a89 diff: don't load color config in plumbing
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

c659f55b31 config: refactor get_colorbool function
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.

daa0c3d971 color: delay auto-color decision until point of use
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.

06bb643b72 commit: reduce use of redundant global variables
The file-scope global variable head_sha1[] was used to hold the object
name of the current HEAD commit (unless we are about to make an initial
commit). Also there is an independent "static int initial_commit".

Fix all the functions on the call-chain that use these two variables to
take a new "(const) struct commit *current_head" argument instead, and
replace their uses, e.g. "if (initial_commit)" becomes "if (!current_head)"
and a reference to "head_sha1" becomes "current_head->object.sha1".

e269eb7946 git_config_colorbool: refactor stdout_is_tty handling
Usually this function figures out for itself whether stdout
is a tty. However, it has an extra parameter just to allow
git-config to override the auto-detection for its
--get-colorbool option.

Instead of an extra parameter, let's just use a global
variable. This makes calling easier in the common case, and
will make refactoring the colorbool code much simpler.

f1c9626105 diff: refactor COLOR_DIFF from a flag into an int
This lets us store more than just a bit flag for whether we
want color; we can also store whether we want automatic
colors. This can be useful for making the automatic-color
decision closer to the point of use.

This mostly just involves replacing DIFF_OPT_* calls with
manipulations of the flag. The biggest exception is that
calls to DIFF_OPT_TST must check for "o->use_color > 0",
which lets an "unknown" value (i.e., the default) stay at
"no color". In the previous code, a value of "-1" was not
propagated at all.

2e6c012e10 setup_pager: set GIT_PAGER_IN_USE
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.

d960c47a88 test-lib: add helper functions for config
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".

When this code was first written (v1.4.3-rc1~174^2~4, merge-recur: if
there is no common ancestor, fake empty one, 2006-08-09), everyone
needing a fake empty tree had to make her own, but ever since
v1.5.5-rc0~180^2~1 (2008-02-13), the object lookup machinery provides
a ready-made one.  Use it.

This is just a simplification, though it also fixes a small leak
(since the tree in the virtual common ancestor commit is never freed).

2a6f08ac1f am: refresh the index at start and --resolved
If a file is unchanged but stat-dirty, we may erroneously
fail to apply patches, thinking that they conflict with a
dirty working tree.

This patch adds a call to "update-index --refresh". It comes
as late as possible, so that we don't bother with it for
thinks like "git rebase --abort", or when mbox-splitting
fails. However, it does come before we actually start
applying patches, meaning we will only call it once when we
start applying patches (or any time we return to "am" after
having resolved conflicts), and not once per patch.

127f045222 revert: plug memory leak in "cherry-pick root commit" codepath
The empty tree passed as common ancestor to merge_trees() when
cherry-picking a parentless commit is allocated on the heap and never
freed.  Leaking such a small one-time allocation is not a very big
problem, but now that "git cherry-pick" can cherry-pick multiple
commits it can start to add up.

Avoid the leak by storing the fake tree exactly once in the BSS
section (i.e., use a static).  While at it, let's add a test to make
sure cherry-picking multiple parentless commits continues to work.

8fb3ad76b1 fast-import: prevent producing bad delta
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.

9a0edb79f2 fast-import: add a test for tree delta base corruption
fast-import is able to write imported tree objects in delta format.
It holds a tree structure in memory where each tree entry may have
a delta base sha1 assigned. When delta base data is needed it is
reconstructed from this in-memory structure. Though sometimes the
delta base data doesn't match the delta base sha1 so wrong or even
corrupt pack is produced.

Add a small test that produces a corrupt pack. It uses just tree

and blob commands.

814f7d902b t3030: fix accidental success in symlink rename
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.

434b8525e7 merge-recursive: Consider modifications in rename/rename(2to1) conflicts
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.

ec61d14963 merge-recursive: Fix modify/delete resolution in the recursive case
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.)

5b448b8530 merge-recursive: When we detect we can skip an update, actually skip it
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().

The code for rename_rename_2to1 conflicts (two files both being renamed to
the same filename) was dead since the rename/add path was always being
independently triggered for each of the renames instead.  Further,
reviving the dead code showed that it was inherently buggy and would
always segfault -- among a few other bugs.

Move the else-if branch for the rename/rename block before the rename/add
block to make sure it is checked first, and fix up the rename/rename(2to1)
code segments to make it handle most cases.  Work is still needed to
handle higher dimensional corner cases such as rename/rename/modify/modify
issues.

531357a4cc merge-recursive: Fix deletion of untracked file in rename/delete conflicts
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.

0b30e81251 merge-recursive: Avoid working directory changes during recursive case
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.

c6966068fb t6042: Add failing testcases for rename/rename/add-{source,dest} conflicts
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.

ac6e839241 t6042: Add tests for content issues with modify/rename/directory conflicts
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
 $ cd 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
    error: pathspec 'Documentation/nosuch.txt' did not match...
    $ git commit nosuch.txt
    error: pathspec 'nosuch.txt' did not match...

7f684a2aff Tolerate zlib deflation with window size < 32Kb
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.

So now you can apply patches from GMail with "git am" in three steps:

 1. choose "show original"
 2. tell the browser to "save as" (for example by pressing Ctrl+S)
 3. run "git am" on the saved file

This fixes a regression introduced by v1.6.4-rc0~15^2~2 (git-am
foreign patch support: autodetect some patch formats, 2009-05-27).
GMail support was first introduced to "git am" by v1.5.4-rc0~274^2
(Make mailsplit and mailinfo strip whitespace from the start of the
input, 2007-11-01).

53f53cff24 fsck: improve committer/author check
fsck allows a name with > character in it like "name> <email>". Also for
"name email>" fsck says "missing space before email".

More precisely, it seeks for a first '<', checks that ' ' preceeds it.
Then seeks to '<' or '>' and checks that it is the '>'. Missing space is
reported if either '<' is not found or it's not preceeded with ' '.

Change it to following. Seek to '<' or '>', check that it is '<' and is
preceeded with ' '. Seek to '<' or '>' and check that it is '>'. So now
"name> <email>" is rejected as "bad name". More strict name check is the
only change in what is accepted.

Report 'missing space' only if '<' is found and is not preceeded with a
space.

4b4963c0e1 fast-import: check committer name more strictly
The documentation declares following identity format:
(<name> SP)? LT <email> GT
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
space is mandatory. And the space quirk is already handled via
extending the string to the left when needed.

Modify fast-import input identity format to a slightly stricter
one - deny LF, LT and GT in both <name> and <email>. And check
for it.

This is stricter then git-fsck as fsck accepts "Name> <email>"
currently, but soon fsck check will be adjusted likewise.

17fb00721b fast-import: don't fail on omitted committer name
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.
Though the parsing is still loose and can accept a ill-formed input.

0687628466 Reduce parse-options.o dependencies
Currently parse-options.o pulls quite a big bunch of dependencies.
his complicates it's usage in contrib/ because it pulls external
dependencies and it also increases executables size.

Split off less generic and more internal to git part of
parse-options.c to parse-options-cb.c.

Move prefix_filename function from setup.c to abspath.c. abspath.o
and wrapper.o pull each other, so it's unlikely to increase the
dependencies. It was a dependency of parse-options.o that pulled
many others.

Now parse-options.o pulls just abspath.o, ctype.o, strbuf.o, usage.o,
wrapper.o, libc directly and strlcpy.o indirectly.

23ce5c39dc t3900: do not reference numbered arguments from the test script
The call to test_expect_success is nested inside a function, whose
arguments the test code wants to access. But it is not specified that any
unexpanded $1, $2, $3, etc in the test code will access the surrounding
function's arguments. Rather, they will access the arguments of the
function that happens to eval the test code.

In this case, the reference is intended to supply '-m message' to a call of
'git commit --squash'. Remove it because -m is optional and the test case
does not check for it. There are tests in t7500 that check combinations of
--squash and -m.

051e4005a3 helping smart-http/stateless-rpc fetch race
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.

Teach upload-pack (which is the workhorse driven by git-daemon and smart
http server interface) that it is OK for a smart-http client to ask for
commits that are not at the tip of any advertised ref, as long as they are
reachable from advertised refs.

0906f6e14e filter-branch: Export variable `workdir' for --commit-filter
According to `git help filter-branch':

       --commit-filter <command>
           ...
           You can use the _map_ convenience function in this filter,
           and other convenience functions, too...
           ...

However, it turns out that `map' hasn't been usable because it depends
on the variable `workdir', which is not propogated to the environment
of the shell that runs the commit-filter <command> because the
shell is created via a simple-command rather than a compound-command
subshell:

 @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
                 $(git write-tree) $parentstr < ../message > ../map/$commit ||
                         die "could not write rewritten commit"

One solution is simply to export `workdir'. However, it seems rather
heavy-handed to export `workdir' to the environments of all commands,
so instead this commit exports `workdir' for only the duration of the
shell command in question:

 workdir=$workdir @SHELL_PATH@ -c "$filter_commit" "git commit-tree" \
                 $(git write-tree) $parentstr < ../message > ../map/$commit ||
                         die "could not write rewritten commit"

3da5c54340 gettext: add gettextln, eval_gettextln to encode common idiom
Currently, if you want to use gettext or eval_gettext to format a message
you may have to add a separate echo statement and a surrounding subshell
in order to interpolate the required trailing new line.

This patch introduces two new helper functions, gettextln and eval_gettextln
which append a trailing newline to the gettext output.

This allows constructions of the form:

	if test -s "$GIT_DIR/BISECT_START"
	then
		(
			gettext "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" &&
			echo
		) >&2
	else
	...

to be expressed more concisely as:

	if test -s "$GIT_DIR/BISECT_START"
	then
		gettextln "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" >&2

a7c58f280a test: cope better with use of return for errors
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.

aa0bcf962a test: simplify return value of test_run_
As v0.99.5~24^2~4 (Trapping exit in tests, using return for errors,
2005-08-10) explains, callers to test_run_ (such as test_expect_code)
used to check the result from eval and the return value separately so
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,
2010-10-03 and especially v1.5.5-rc0~271, 2008-02-01) but the weird
two-return-value calling convention lives on.

Let's get rid of it.  The new rule: test_run_ succeeds (returns 0)
if and only if the test succeeded.

6280dfdc3b fast-export: quote paths in output
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.

f5114a40c0 git-check-attr: Normalize paths
Normalize the path arguments (relative to the working tree root, if
applicable) before looking up their attributes.  This requires passing
the prefix down the call chain.

This fixes two test cases for different reasons:

* "unnormalized paths" is fixed because the .gitattribute-file-seeking
  code is not confused into reading the top-level file twice.

* "relative paths" is fixed because the canonical pathnames are passed
  to get_check_attr() or get_all_attrs(), allowing them to match the
  pathname patterns as expected.

5d2fc9135a docs: put listed example commands in backticks
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.

It can also be used in other cases where actual checkout of the tree
is not required to progress the bisection.

9969454435 diff -c/--cc: do not mistake "resolved as deletion" as "use working tree"
The combined diff machinery can be used to compare:

 - a merge commit with its parent commits;
 - a working-tree file with multiple stages in an unmerged index; or
 - a working-tree file with the HEAD and the index.

The internal function combine-diff.c:show_patch_diff() checked if it needs
to read the "result" from the working tree by looking at the object name
of the result --- if it is null_sha1, it read from the working tree.

This mistook a merge that records a deletion as the conflict resolution
as if it is a cue to read from the working tree. Pass this information
explicitly from the caller instead.

8894d53580 commit: allow partial commits with relative paths
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.

fc1b56f054 notice error exit from pager
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.

402e8a6d9a Documentation/submodule: add command references and update options
Reference the "git diff" and "git status" commands where they learned
functionality that in earlier git versions was only available through the
'summary' and 'status' subcommands of "git submodule".

The short option '-n' for '--summary-limit' was missing from the synopsis
and the --init option was missing from the "options" section, add those
there. And while at it, quote all options in backticks so they are
decorated properly in the output formats which support that.

bf01d4a334 reflog: actually default to subcommand 'show'
The reflog manpage says:

	git reflog [show] [log-options] [<ref>]

the subcommand 'show' is the default "in the absence of any
subcommands". Currently this is only true if the user provided either
at least one option or no additional argument at all. For example:

	git reflog master

won't work. Change this by actually calling cmd_log_reflog in
absence of any subcommand.

mechanism to only log connection errors if all attempts failed
was introduced for the IPv6 code-path, but not for the IPv4 one.

Introduce a matching mechanism so IPv4-users also benefit from
this noise-reduction.

This behaviour isn't very useful, so let's fix it by increasing

dd008b3b11 t7400: fix bogus test failure with symlinked trash
One of the tests in t7400 fails if the trash directory has a
symlink anywhere in its path. E.g.:

  $ mkdir /tmp/git-test
  $ mkdir /tmp/git-test/real
  $ ln -s real /tmp/git-test/link

  $ ./t7400-submodule-basic --root=/tmp/git-test/real
  ...
  # passed all 44 test(s)

  $ ./t7400-submodule-basic --root=/tmp/git-test/link
  ...
  not ok - 41 use superproject as upstream when path is relative and no url is set there

The failing test does:

  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).

Fix this by asking pwd to canonicalize the name of the trash
directory for us.

131d6afcba gitweb: Introduce common system-wide settings for convenience
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

2579e1d293 tests: print failed test numbers at the end of the test run
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

This makes it possible to just run the test suite with -i and collect all
failed test scripts at the end for further examination.

95dea6eb50 streaming: free git_istream upon closing
Kirill Smelkov noticed that post-1.7.6 "git checkout"
started leaking tons of memory. The streaming_write_entry
function properly calls close_istream(), but that function
did not actually free() the allocated git_istream struct.

The git_istream struct is totally opaque to calling code,
and must be heap-allocated by open_istream. Therefore it's
not appropriate for callers to have to free it.

This patch makes close_istream() into "close and de-allocate
all associated resources". We could add a new "free_istream"
call, but there's not much point in letting callers inspect
the istream after close. And this patch's semantics make us
match fopen/fclose, which is well-known and understood.

b421812b48 doc/fast-import: clarify notemodify command
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.

d04520e344 reset: give better reflog messages
The reset command creates its reflog entry from argv.
However, it does so after having run parse_options, which
means the only thing left in argv is any non-option
arguments. Thus you would end up with confusing reflog
entries like:

  $ git reset --hard HEAD^
  $ git reset --soft HEAD@{1}
  $ git log -2 -g --oneline
  8e46cad HEAD@{0}: HEAD@{1}: updating HEAD
  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

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.

9504bc9d5a transport-helper: change import semantics
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'.

1f25c50419 transport-helper: use the new done feature where possible
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.

be56862f19 fast-import: introduce 'done' command
Add a 'done' command that causes fast-import to stop reading from the
stream and exit.

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
teach fast-import to do that --- fast-import still uses buffered input
(stdio).

b4b872994b git_remote_helpers: push all refs during a non-local export
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
yet exist in the remote repo.

3ea7d09461 transport-helper: don't feed bogus refs to export push
When we want to push to a remote helper that has the
"export" capability, we collect all of the refs we want to
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
have the ref at all).

4e51ba238f git-remote-testgit: import non-HEAD refs
Upon receiving an "import" command, the testgit remote
helper would ignore the ref asked for by git and generate a
fast-export stream based on HEAD. Instead, we should
actually give git the ref it asked for.

This requires adding a new parameter to the export_repo
method in the remote-helpers python library, which may be
used by code outside of git.git. We use a default parameter
so that callers without the new parameter will get the same
behavior as before.

c00dd33b1f t5800: document some non-functional parts of remote helpers
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".

The description for 'git rebase --abort' currently says:

    Restore the original branch and abort the rebase operation.

The "restore" can be misinterpreted to imply that the original branch
was somehow in a broken state during the rebase operation. It is also
not completely clear what "the original branch" is --- is it the
branch that was checked out before the rebase operation was called or
is the the branch that is being rebased (it is the latter)? Although
both issues are made clear in the DESCRIPTION section, let us also
make the entry in the OPTIONS secion more clear.

Also remove the term "rebasing process" from the usage text, since the

86abba8015 xdiff/xprepare: use a smaller sample size for histogram diff
For histogram diff, we can afford a smaller sample size and thus a
poorer estimate of the number of lines, as the hash table (rhash) won't
be filled up/grown. This is safe as the final count of lines (xdf.nrecs)
will be updated correctly anyway by xdl_prepare_ctx().

This gives us a small boost in performance.

9f37c27593 xdiff/xprepare: skip classification
xdiff performs "classification" of records (xdl_classify_record()),
replacing hashes (xrecord_t.ha) with a unique identifier of the
record/line and building a hash table (xrecord_t.rhash) of records. This
is then used to "cleanup" records (xdl_cleanup_records()).

We don't need any of that in histogram diff, so we omit calls to these
functions. We also skip allocating memory to the hash table, rhash, as
it is no longer used.

This gives us a small boost in performance.

8c912eea94 teach --histogram to diff
Port JGit's HistogramDiff algorithm over to C. Rough numbers (TODO) show
that it is faster than its --patience cousin, as well as the default
Meyers algorithm.

The implementation has been reworked to use structs and pointers,
instead of bitmasks, thus doing away with JGit's 2^28 line limit.

We also use xdiff's default hash table implementation (xdl_hash_bits()
with XDL_HASHLONG()) for convenience.

7d092adc8f get_pwd_cwd(): Do not trust st_dev/st_ino blindly
10c4c88 (Allow add_path() to add non-existent directories to the path,
2008-07-21) introduced get_pwd_cwd() function in order to favor $PWD when
getenv("PWD") and getcwd() refer to the same directory but are different
strings (e.g. the former gives a nicer looking name via a symbolic link to
an uglier looking automounted path). The function tried to determine if
two directories are the same by running stat(2) on both and comparing
ino/dev fields.

Unfortunately, stat() does not fill any ino or dev fields in msysgit.  But
there is a telltale: both ino and dev are 0 when they are not filled
correctly, so let's be extra cautious.

This happens to fix a bug in "get-receive-pack working_directory/" when
the GIT_DIR would not be set correctly due to absolute_path(".")
returning the wrong value.

6b01ecfe22 ref namespaces: Support remote repositories via upload-pack and receive-pack
Change upload-pack and receive-pack to use the namespace-prefixed refs
when working with the repository, and use the unprefixed refs when
talking to the client, maintaining the masquerade.  This allows
clone, pull, fetch, and push to work with a suitably configured
GIT_NAMESPACE.

receive-pack advertises refs outside the current namespace as .have refs
(as it currently does for refs in alternates), so that the client can
use them to minimize data transfer but will otherwise ignore them.

With appropriate configuration, this also allows http-backend to expose
namespaces as multiple repositories with different paths.  This only
requires setting GIT_NAMESPACE, which http-backend passes through to
upload-pack and receive-pack.

1b4bb16b9e pack-objects: optimize "recency order"
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
   against each other.

I tried various workloads in the Linux kernel repositories (HEAD at
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.

 * Simple commit-only log.

   $ git log >/dev/null

   There are 254656 commits in total.

   95% of the pack accesses look at data that is no further than 260kB
   from the previous location we accessed. The patch does not change the
   order of commit objects very much, and the result is very similar.

       Less than 2MiB seek:       61.71%      62.87%

   With the current pack heuristics, more than 30% of accesses have to
   seek further than 300MB; the updated pack heuristics ensures that less
   than 0.1% of accesses have to seek further than 135MB. This is largely
   due to the fact that the updated heuristics does not mix blobs and
   trees together.

   The result is very similar to the pathspec-limited log above, which

 * Packing recent history.

   $ (git for-each-ref --format='^%(refname)' refs/tags; echo HEAD) |
     git pack-objects --revs --stdout >/dev/null

   This should pack data worth 71 commits.

       Less than 2MiB seek:       77.09%      99.04%

    The long-tail part of the result looks worse with the patch, but
    the change helps majority of the access. 99.04% of the accesses
    need less than 2MiB of seeking, compared to 77.09% with the current
    packing heuristics.

       Less than 2MiB seek:       81.73%      96.92%

   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.

5f44324d88 core: log offset pack data accesses happened
In a workload other than "git log" (without pathspec nor any option that
causes us to inspect trees and blobs), the recency pack order is said to
cause the access jump around quite a bit. Add a hook to allow us observe
how bad it is.

"git config core.logpackaccess /var/tmp/pal.txt" will give you the log
in the specified file.

c5bcf1f9f6 checkout: do not write bogus reflog entry out
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.

7791a1d9b9 Documentation: use [verse] for SYNOPSIS sections
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.

a1bea2c1fc ref namespaces: infrastructure
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.

b3cfc4066d Fix prefix handling in ref iteration functions
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.

This patch doesn't implement auto-detection of skew, but is the program
I used to calculate, and would provide the basis for such
auto-detection. It would be interesting to see average skew numbers for
popular repositories. You can run it as "git skew --all".

e8c3531717 gitweb: Serve */*+xml 'blob_plain' as text/plain with $prevent_xss
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.

4dca1aa650 git-submodule.sh: preserve stdin for the command spawned by foreach
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.

b586744a86 test: skip clean-up when running under --immediate mode
Some tests try to be too careful about cleaning themselves up and
do

    test_expect_success description '
        set-up some test refs and/or configuration &&
        test_when_finished "revert the above changes" &&
	the real test
    '

Which is nice to make sure that a potential failure would not have
unexpected interaction with the next test. This however interferes when
"the real test" fails and we want to see what is going on, by running the
test with --immediate mode and descending into its trash directory after
the test stops. The precondition to run the real test and cause it to fail
is all gone after the clean-up procedure defined by test_when_finished is
done.

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.

27269fc5f2 Documentation/i18n: quote double-dash for AsciiDoc
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.

  Documentation: quote double-dash for AsciiDoc
2011-06-29 09:25:51 -07:00
565e135a1e Documentation: quote double-dash for AsciiDoc
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).

5ad6d387f1 git-instaweb: Check that correct config file exists for (re)start
Currently start/restart does not generate any configuration files for
spawning a new instance.  This means that

  $ git instaweb --http=<server> --start

might pick up stale 'httpd.conf' file for a different web server
(e.g. for default lighttpd when requesting apache2).

This commit changes that, and makes git-instaweb generate web server
config file and/or gitweb config file if don't exists.

This required naming config files after the name of web server
(alternate solution would be to somehow mark for which web server was
config file generated).

Note that web servers that embed configuration in server script file,
namely webrick and plackup, and which delete "$conf" in their *_conf
function, would have their config (server script) always regenerated.

Note: this commit introduces a bit of code repetition (but only a few
lines).

2cd9de3e18 submodule add: always initialize .git/config entry
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.

ccee60862b submodule sync: do not auto-vivify uninteresting submodule
Earlier 33f072f (submodule sync: Update "submodule.<name>.url" for empty
directories, 2010-10-08) attempted to fix a bug where "git submodule sync"
command does not update the URL if the current superproject does not have
a checkout of the submodule.

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.

Update the code so that the URL is updated from the .gitmodules file only
for submodules that already have submodule.$name.url entries, i.e. the
ones the user has showed interested in having a checkout.

787513027a stash: Add --include-untracked option to stash and remove all untracked files
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).

It was correct to say "The file $GIT_DIR/refs/heads/master stores the

but not anymore, as refs can be packed into $GIT_DIR/packed-refs file.

Update the document to talk in terms of a more abstract concept "ref" and
"symbolic ref" where we are not describing the underlying implementation
detail.

This on purpose leaves two instances of $GIT_DIR/ in the git-remote
documentation; they do talk about $GIT_DIR/remotes/ and $GIT_DIR/branches/
file hierarchy that used to be the place to store configuration around
remotes before the configuration mechanism took them over.

84054f79de clone: accept config options on the command line
Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.

In many cases, this is a minor convenience over something
like:

  git clone git://...
  git config core.whatever true

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
helpers during a clone; the helpers may read the git config
to influence how they operate.

1c2c9bee1b config: die on error in command-line config
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.

fields, and for the final field to contain "everything
else", even if it includes the delimiter.

This patch introduces strbuf_split_max, which provides a
"max number of fields" parameter; it behaves similarly to
perl's "split" with a 3rd field.

The existing 2-argument form of strbuf_split is retained for
compatibility and ease-of-use.

Some tar filters may be very expensive to run, so sites do

767cf4579f archive: implement configurable tar filters
It's common to pipe the tar output produce by "git archive"
through gzip or some other compressor. Locally, this can
easily be done by using a shell pipe. When requesting a
remote archive, though, it cannot be done through the
upload-archive interface.

This patch allows configurable tar filters, so that one
could define a "tar.gz" format that automatically pipes tar
output through gzip.

08716b3c11 archive: refactor file extension format-guessing
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.

56baa61d01 archive: move file extension format-guessing lower
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.

4d7c989863 archive: pass archiver struct to write_archive callback
The current archivers are very static; when you are in the
write_tar_archive function, you know you are writing a tar.
However, to facilitate runtime-configurable archivers
that will share a common write function we need to tell the
function which archiver was used.

As a convenience, we also provide an opaque data pointer in
the archiver struct so that individual archivers can put
something useful there when they register themselves.
Technically they could just use the "name" field to look in

Most of the tar and zip code was nicely split out into two
abstracted files which knew only about their specific

However, as these basic formats grow more complex (e.g., by

7ddc2710b9 Add profile feedback build to git
Add a gcc profile feedback build option "profile-all" to the main
Makefile. It simply runs the test suite to generate feedback data and the
recompiles the main executables with that. The basic structure is similar
to the existing gcov code.

gcc is often able to generate better code with profile feedback data. The
training load also doesn't need to be too similar to the actual load, it
still gives benefits.

The test suite run is unfortunately quite long. It would be good to find a
suitable subset that runs faster and still gives reasonable feedback.

For now the test suite runs single threaded (I had some trouble running
the test suite with -jX)

I tested it with git gc and git blame kernel/sched.c on a Linux kernel
tree. For gc I get about 2.7% improvement in wall clock time by using the
feedback build, for blame about 2.4%.  That's not gigantic, but not shabby
either for a very small patch.

If anyone has any favourite CPU intensive git benchmarks feel free to try
them too.

I hope distributors will switch to use a feedback build in their packages.

12bf828348 rebase -i -p: include non-first-parent commits in todo list
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).

executable that starts with git-* or test-* into a special

However, shell libraries like git-sh-setup do not have the

924aaf3ef7 config.c: Make git_config() work correctly when called recursively
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.

452993c297 t1301-*.sh: Fix the 'forced modes' test on cygwin
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.

b8a9733377 help.c: Fix detection of custom merge strategy on cygwin
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.)

2321286298 archive: reorder option parsing and config reading
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.

877449c136 git-submodule.sh: clarify the "should we die now" logic
Earlier the decision to stop or continue was made on the $action variable
that was set by inspecting $update_module variable. The former is a
redundant variable and will be removed in another topic.

Decide upon inspecting $update_module if a failure should cascade up to
cause us immediately stop, and use a variable that means just that, to
clarify the logic.

Incidentally this also makes the merge with the other topic slightly
easier and cleaner to understand.

15ffb7cde4 submodule update: continue when a checkout fails
"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.

0c811a7a6f limit "contains" traversals based on commit timestamp
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).

ffc4b8012d tag: speed up --contains calculation
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
  sys     0m0.220s

to:

  real    0m5.329s

e01503b523 zlib: allow feeding more than 4GB in one go
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.

ef49a7a012 zlib: zlib can only process 4GB at a time
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.

2c162b56f3 gitweb: do not misparse nonnumeric content tag files that contain a digit
v1.7.6-rc0~27^2~4 (gitweb: Change the way "content tags" ('ctags') are
handled, 2011-04-29) tried to make gitweb's tag cloud feature more
intuitive for webmasters by checking whether the ctags/<label> under
a project's .git dir contains a number (representing the strength of
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"
error can still be experienced if you write "Linux-2.6" in place of
"Linux" in the example above.  Fix it by tightening the pattern to
^\d+$.

cc5c54e78b sha1_file.c: "legacy" is really the current format
Every time I look at the read-loose-object codepath, legacy_loose_object()
function makes my brain go through mental contortion. When we were playing
with the experimental loose object format, it may have made sense to call
the traditional format "legacy", in the hope that the experimental one
will some day replace it to become official, but it never happened.

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
objects in experimental format is the "unlikely" case.

Someday after Git 2.0, we should drop the support of this format.

c1921c184c clone: always fetch remote HEAD
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.

df599e9612 Windows: teach getenv to do a case-sensitive search

case-insensitive, it is possible for applications to pass an environment

Windows does this, for example, and sh-i18n--envsubst depends on this
behavior.

substantially.

To ensure consistent behavior in the future, change all getenv callers

walks objects in the packfile in their object name order and replaces it

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"

c17b229454 checkout -b <name>: correctly detect existing branch
When create a new branch, we fed "refs/heads/<proposed name>" as a string

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.

08303c3636 grep: fix coloring of hunk marks between files
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.

61adfd3097 consider only branches in guess_remote_head
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.

3b368546a0 t: add tests for cloning remotes with detached 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.

bcfb95dde4 http: pass http.cookiefile using CURLOPT_COOKIEFILE
If the config option http.cookiefile is set, pass this file to libCURL using
the CURLOPT_COOKIEFILE option. This is similar to calling curl with the -b
option.  This allows git http authorization with authentication mechanisms
that use cookies, such as SAML Enhanced Client or Proxy (ECP) used by
Shibboleth.

To use SAML/ECP, the user needs to request a session cookie with their own ECP
code. See for example:

<https://wiki.shibboleth.net/confluence/display/SHIB2/ECP>

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

git config --global http.cookiefile "/home/dbrown/.curlcookies"

libCURL will then pass the appropriate session cookies to the git http server.

status-print-untracked, 2010-04-10) converted the
wt_status_print_untracked function into
wt_status_print_other, taking a string_list of either
untracked or ignored items to print. However, the "nothing

show the ignored items.

b4194828dc diff-index --quiet: learn the "stop feeding the backend early" logic
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.

af7b41c923 diff_tree: disable QUICK optimization with diff filter
We stop looking for changes early with QUICK, so our diff
queue contains only a subset of the changes. However, we
don't apply diff filters until later; it will appear at that
point as though there are no changes matching our filter,
when in reality we simply didn't keep looking for changes
long enough.

Commit 2cfe8a6 (diff --quiet: disable optimization when
--diff-filter=X is used, 2011-03-16) fixes this in some
cases by disabling the optimization when a filter is
present. However, it only tweaked run_diff_files, missing
the similar case in diff_tree. Thus the fix worked only for
diffing the working tree and index, but not between trees.

42ab5d40de gitweb.js: use setTimeout rather than setInterval in blame_incremental.js
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.

While at it get rid of `xhr' global variable, creating it instead as
local variable in startBlame and passing it as parameter, and of
`pollTimer' global variable, passing it as member of xhr object
(xhr.pollTimer).

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.

4d5f347199 combine-diff: handle binary files as binary
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.

c95b99bb5d combine-diff: calculate mode_differs earlier
One loop combined both the patch generation and checking

that into two separate loops, as we may care about the mode
change even if we are not generating patches (e.g., because
we are showing a binary diff, which will come in a future
patch).

dd8e912190 streaming_write_entry(): use streaming API in write_entry()
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.

Given an object name, use open_istream() to get a git_istream handle
that you can read_istream() from as if you are using read(2) to read
the contents of the object, and close it with close_istream() when
you are done.

Currently, we do not do anything fancy--it just calls read_sha1_file()
and keeps the contents in memory as a whole, and carve it out as you
request with read_istream().

to give us a quick access if we read_sha1_file() it right now,
which is a piece of useful information.

9a49059022 sha1_object_info_extended(): expose a bit more info
The original interface for sha1_object_info() takes an object name and
gives back a type and its size (the latter is given only when it was
asked).  The new interface wraps its implementation and exposes a bit
more pieces of information that the interface used to discard, namely:

 - where the object is stored (loose? cached? packed?)
 - if packed, where in which packfile?

 * In the earlier round, this used u.pack.delta to record the length of
   the delta chain, but the caller is not necessarily interested in the
   length of the delta chain per-se, but may only want to know if it is a
   delta against another object or is stored as a deflated data. Calling
   packed_object_info_detail() involves walking the reverse index chain to
   compute the store size of the object and is unnecessarily expensive.

   We could resurrect the code if a new caller wants to know, but I doubt
   it.

3c9fc074c2 index-pack --verify: read anomalous offsets from v2 idx file
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.

e337a04de2 index-pack: --verify
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.

7218a215ef index-pack: group the delta-base array entries also by type
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.

Group the entries also by type to eliminate the potential of false hits.

Git v1.7.6.1 Release Notes
==========================
Fixes since v1.7.6
------------------
* Various codepaths that invoked zlib deflate/inflate assumed that these
functions can compress or uncompress more than 4GB data in one call on
platforms with 64-bit long, which has been corrected.
* "git unexecutable" reported that "unexecutable" was not found, even
though the actual error was that "unexecutable" was found but did
not have a proper she-bang line to be executed.
* Error exits from $PAGER were silently ignored.
* "git checkout -b <branch>" was confused when attempting to create a
branch whose name ends with "-g" followed by hexadecimal digits,
and refused to work.
* "git checkout -b <branch>" sometimes wrote a bogus reflog entry,
causing later "git checkout -" to fail.
* "git diff --cc" learned to correctly ignore binary files.
* "git diff -c/--cc" mishandled a deletion that resolves a conflict, and
looked in the working tree instead.
* "git fast-export" forgot to quote pathnames with unsafe characters
in its output.
* "git fetch" over smart-http transport used to abort when the
repository was updated between the initial connection and the
subsequent object transfer.
* "git fetch" did not recurse into submodules in subdirectories.
* "git ls-tree" did not error out when asked to show a corrupt tree.
* "git pull" without any argument left an extra whitespace after the
command name in its reflog.
* "git push --quiet" was not really quiet.
* "git rebase -i -p" incorrectly dropped commits from side branches.
* "git reset [<commit>] paths..." did not reset the index entry correctly
for unmerged paths.
* "git submodule add" did not allow a relative repository path when
the superproject did not have any default remote url.
* "git submodule foreach" failed to correctly give the standard input to
the user-supplied command it invoked.
* submodules that the user has never showed interest in by running
"git submodule init" was incorrectly marked as interesting by "git
submodule sync".
* "git submodule update --quiet" was not really quiet.
* "git tag -l <glob>..." did not take multiple glob patterns from the
command line.

Git v1.7.7 Release Notes
========================
Updates since v1.7.6
--------------------
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Interix, Cygwin and Minix ports got updated.
* Various updates to git-p4 (in contrib/), fast-import, and git-svn.
* Gitweb learned to read from /etc/gitweb-common.conf when it exists,
before reading from gitweb_config.perl or from /etc/gitweb.conf
(this last one is read only when per-repository gitweb_config.perl
does not exist).
* Various codepaths that invoked zlib deflate/inflate assumed that these
functions can compress or uncompress more than 4GB data in one call on
platforms with 64-bit long, which has been corrected.
* Git now recognizes loose objects written by other implementations that
use a non-standard window size for zlib deflation (e.g. Agit running on
Android with 4kb window). We used to reject anything that was not
deflated with 32kb window.
* Interaction between the use of pager and coloring of the output has
been improved, especially when a command that is not built-in was
involved.
* "git am" learned to pass the "--exclude=<path>" option through to underlying
"git apply".
* You can now feed many empty lines before feeding an mbox file to
"git am".
* "git archive" can be told to pass the output to gzip compression and
produce "archive.tar.gz".
* "git bisect" can be used in a bare repository (provided that the test
you perform per each iteration does not need a working tree, of
course).
* The length of abbreviated object names in "git branch -v" output
now honors the core.abbrev configuration variable.
* "git check-attr" can take relative paths from the command line.
* "git check-attr" learned an "--all" option to list the attributes for a
given path.
* "git checkout" (both the code to update the files upon checking out a
different branch and the code to checkout a specific set of files) learned
to stream the data from object store when possible, without having to
read the entire contents of a file into memory first. An earlier round
of this code that is not in any released version had a large leak but
now it has been plugged.
* "git clone" can now take a "--config key=value" option to set the
repository configuration options that affect the initial checkout.
* "git commit <paths>..." now lets you feed relative pathspecs that
refer to outside your current subdirectory.
* "git diff --stat" learned a --stat-count option to limit the output of
a diffstat report.
* "git diff" learned a "--histogram" option to use a different diff
generation machinery stolen from jgit, which might give better
performance.
* "git diff" had a weird worst case behaviour that can be triggered
when comparing files with potentially many places that could match.
* "git fetch", "git push" and friends no longer show connection
errors for addresses that couldn't be connected to when at least one
address succeeds (this is arguably a regression but a deliberate
one).
* "git grep" learned "--break" and "--heading" options, to let users mimic
the output format of "ack".
* "git grep" learned a "-W" option that shows wider context using the same
logic used by "git diff" to determine the hunk header.
* Invoking the low-level "git http-fetch" without "-a" option (which
git itself never did---normal users should not have to worry about
this) is now deprecated.
* The "--decorate" option to "git log" and its family learned to
highlight grafted and replaced commits.
* "git rebase master topci" no longer spews usage hints after giving
the "fatal: no such branch: topci" error message.
* The recursive merge strategy implementation got a fairly large
fix for many corner cases that may rarely happen in real world
projects (it has been verified that none of the 16000+ merges in
the Linux kernel history back to v2.6.12 is affected with the
corner case bugs this update fixes).
* "git stash" learned an "--include-untracked option".
* "git submodule update" used to stop at the first error updating a
submodule; it now goes on to update other submodules that can be
updated, and reports the ones with errors at the end.
* "git push" can be told with the "--recurse-submodules=check" option to
refuse pushing of the supermodule, if any of its submodules'
commits hasn't been pushed out to their remotes.
* "git upload-pack" and "git receive-pack" learned to pretend that only a
subset of the refs exist in a repository. This may help a site to
put many tiny repositories into one repository (this would not be
useful for larger repositories as repacking would be problematic).
* "git verify-pack" has been rewritten to use the "index-pack" machinery
that is more efficient in reading objects in packfiles.
* test scripts for gitweb tried to run even when CGI-related perl modules
are not installed; they now exit early when the latter are unavailable.
Also contains various documentation updates and minor miscellaneous
changes.
Fixes since v1.7.6
------------------
Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
included in this release.
* The error reporting logic of "git am" when the command is fed a file
whose mail-storage format is unknown was fixed.
(merge dff4b0e gb/maint-am-patch-format-error-message later to 'maint').
* "git branch --set-upstream @{-1} foo" did not expand @{-1} correctly.
(merge e9d4f74 mg/branch-set-upstream-previous later to 'maint').
* "git branch -m" and "git checkout -b" incorrectly allowed the tip
of the branch that is currently checked out updated.
(merge 55c4a67 ci/forbid-unwanted-current-branch-update later to 'maint').
* "git check-ref-format --print" used to parrot a candidate string that
began with a slash (e.g. /refs/heads/master) without stripping it, to make
the result a suitably normalized string the caller can append to "$GIT_DIR/".
(merge f3738c1 mh/check-ref-format-print-normalize later to 'maint').
* "git clone" failed to clone locally from a ".git" file that itself
is not a directory but is a pointer to one.
(merge 9b0ebc7 nd/maint-clone-gitdir later to 'maint').
* "git clone" from a local repository that borrows from another
object store using a relative path in its objects/info/alternates
file did not adjust the alternates in the resulting repository.
(merge e6baf4a1 jc/maint-clone-alternates later to 'maint').
* "git describe --dirty" did not refresh the index before checking the
state of the working tree files.
(cherry-pick bb57148 ac/describe-dirty-refresh later to 'maint').
* "git ls-files ../$path" that is run from a subdirectory reported errors
incorrectly when there is no such path that matches the given pathspec.

SYNOPSIS

'git remote-<transport>' <repository> [<URL>]
DESCRIPTION
@ -23,22 +24,141 @@ output. Because a remote helper runs as an independent process from
git, there is no need to re-link git to add a new helper, nor any
need to link the helper with the implementation of git.
Every helper must support the "capabilities" command, which git will
use to determine what other commands the helper will accept. Other
commands generally concern facilities like discovering and updating
remote refs, transporting objects between the object database and
the remote repository, and updating the local object store.
Helpers supporting the 'fetch' capability can discover refs from the
remote repository and transfer objects reachable from those refs to
the local object store. Helpers supporting the 'push' capability can
transfer local objects to the remote repository and update remote refs.
Every helper must support the "capabilities" command, which git
uses to determine what other commands the helper will accept. Those
other commands can be used to discover and update remote refs,
transport objects between the object database and the remote repository,
and update the local object store.
Git comes with a "curl" family of remote helpers, that handle various
transport protocols, such as 'git-remote-http', 'git-remote-https',
'git-remote-ftp' and 'git-remote-ftps'. They implement the capabilities
'fetch', 'option', and 'push'.
INPUT FORMAT
------------
Git sends the remote helper a list of commands on standard input, one
per line. The first command is always the 'capabilities' command, in
response to which the remote helper must print a list of the
capabilities it supports (see below) followed by a blank line. The
response to the capabilities command determines what commands Git uses
in the remainder of the command stream.
The command stream is terminated by a blank line. In some cases
(indicated in the documentation of the relevant commands), this blank
line is followed by a payload in some other protocol (e.g., the pack
protocol), while in others it indicates the end of input.
Capabilities
~~~~~~~~~~~~
Each remote helper is expected to support only a subset of commands.
The operations a helper supports are declared to git in the response
to the `capabilities` command (see COMMANDS, below).
'option'::
For specifying settings like `verbosity` (how much output to
write to stderr) and `depth` (how much history is wanted in the
case of a shallow clone) that affect how other commands are
carried out.
'connect'::
For fetching and pushing using git's native packfile protocol
that requires a bidirectional, full-duplex connection.
'push'::
For listing remote refs and pushing specified objects from the
local object store to remote refs.
'fetch'::
For listing remote refs and fetching the associated history to
the local object store.
'import'::
For listing remote refs and fetching the associated history as
a fast-import stream.
'refspec' <refspec>::
This modifies the 'import' capability, allowing the produced
fast-import stream to modify refs in a private namespace
instead of writing to refs/heads or refs/remotes directly.
It is recommended that all importers providing the 'import'
capability use this.
+
A helper advertising the capability
`refspec refs/heads/{asterisk}:refs/svn/origin/branches/{asterisk}`
is saying that, when it is asked to `import refs/heads/topic`, the
stream it outputs will update the `refs/svn/origin/branches/topic`
ref.
+
This capability can be advertised multiple times. The first
applicable refspec takes precedence. The left-hand of refspecs
advertised with this capability must cover all refs reported by
the list command. If no 'refspec' capability is advertised,
there is an implied `refspec {asterisk}:{asterisk}`.
Capabilities for Pushing
~~~~~~~~~~~~~~~~~~~~~~~~
'connect'::
Can attempt to connect to 'git receive-pack' (for pushing),
'git upload-pack', etc for communication using the
packfile protocol.
+
Supported commands: 'connect'.
'push'::
Can discover remote refs and push local commits and the
history leading up to them to new or existing remote refs.
+
Supported commands: 'list for-push', 'push'.
If a helper advertises both 'connect' and 'push', git will use
'connect' if possible and fall back to 'push' if the helper requests
so when connecting (see the 'connect' command under COMMANDS).
Capabilities for Fetching
~~~~~~~~~~~~~~~~~~~~~~~~~
'connect'::
Can try to connect to 'git upload-pack' (for fetching),
'git receive-pack', etc for communication using the
packfile protocol.
+
Supported commands: 'connect'.
'fetch'::
Can discover remote refs and transfer objects reachable from
them to the local object store.
+
Supported commands: 'list', 'fetch'.
'import'::
Can discover remote refs and output objects reachable from
them as a stream in fast-import format.
+
Supported commands: 'list', 'import'.
If a helper advertises 'connect', git will use it if possible and
fall back to another capability if the helper requests so when
connecting (see the 'connect' command under COMMANDS).
When choosing between 'fetch' and 'import', git prefers 'fetch'.
Other frontends may have some other order of preference.
'refspec' <refspec>::
This modifies the 'import' capability.
+
A helper advertising
`refspec refs/heads/{asterisk}:refs/svn/origin/branches/{asterisk}`
in its capabilities is saying that, when it handles
`import refs/heads/topic`, the stream it outputs will update the
`refs/svn/origin/branches/topic` ref.

This capability can be advertised multiple times. The first
applicable refspec takes precedence. The left-hand of refspecs

If the `--include-untracked` option is used, all untracked files are also
stashed and then cleaned up with `git clean`, leaving the working directory
in a very clean state. If the `--all` option is used instead then the
