'git filter-branch' fails complaining about an ambiguous argument, if
a tree-filter renames a path and the new pathname happens to match an
existing object name.
After the tree-filter has been applied, 'git filter-branch' looks for
changed paths by running:
git diff-index -r --name-only --ignore-submodules $commit
which then, because of the lack of disambiguating double-dash, can't
decide whether to treat '$commit' as revision or path and errors out.
Add that disambiguating double-dash after 'git diff-index's revision
argument to make sure that '$commit' is interpreted as a revision.

When "p4 submit" command fails in P4Submit.applyCommit, the
workspace is left with the changes. We already have code to revert
the changes to the workspace when the user decides to cancel
submission by aborting the editor that edits the change description,
and we should treat the "p4 submit" failure the same way.
Clean the workspace if p4_write_pipe raised SystemExit, so that the
user don't have to do it themselves.

When submitting, git-p4 finds the current branch in
order to know if it is allowed to submit (configuration
"git-p4.allowSubmit").
On a detached head, detecting the branch would fail, and
git-p4 would report a cryptic error.
This change teaches git-p4 to recognise a detached head and
submit successfully.

When passed an ssh:// url, git strips ssh://host from the url but does
not remove leading slashes from the path. So when this test used
ssh://remote//path/to/pwd, the path accessed by our fake SSH is
//path/to/pwd, which cygwin interprets as a UNC path, causing the test
to fail.
We may want to actually fix this in git itself, making it remove extra
slashes from urls before feeding them to transports or helpers, but
that's for another topic as it could cause regressions.

Since ec7dbd145 (receive-pack: allow hooks to ignore its
standard input stream) the pre-receive and post-receive
hooks ignore SIGPIPE. Do the same for the remaining hooks
pre-push and post-rewrite, which read from standard input.
The same arguments for ignoring SIGPIPE apply.
Include test by Jeff King which checks that SIGPIPE does not
cause pre-push hook failure. With the use of git update-ref
--stdin it is fast enough to be enabled by default.

If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.
Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case. This fixes t7060 with --valgrind.

Git-merge-file is documented to return one of three exit
codes:
- zero means the merge was successful
- a negative number means an error occurred
- a positive number indicates the number of conflicts
Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).
This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).
Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform. We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.
This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.
Special case a lone CR and treat it the same way as an empty line to
work this around.
This patch (also) passes the test with Git for Windows, where the
issue was seen first.

If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).
The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion. In many cases that is a sane resolution, but
we should be punting to the user whenever there is any
question. So let's detect and treat this as a conflict (in
both strategies).

This script tests the filemode handling of merge-recursive,
but we do not test the same thing for merge-resolve. Let's
generalize the script a little:
1. Break out the setup steps for each test into a separate
snippet.
2. For each test, run it twice; once with "-s recursive"
and once with "-s resolve". We can avoid repeating
ourselves by adding a function.
3. Since we have a nice abstracted function, we can make
our tests more thorough by testing both directions
(change on "ours" versus "theirs").
This improves our test coverage, and will make this the
place to add more tests related to merging mode changes.

The t6031 test was introduced to check filemode handling of
merge-recursive. Much later, an unrelated test was tacked on
to look at renames and d/f conflicts. This test does not
depend on anything that happened before (it actually blows
away any existing content in the test repo). Let's move it
to t3030, where there are more related tests.

Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory). The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec. At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".
The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be". The parse_pathspec() then would give
us a pathspec that matches everything and all is well.
Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs). The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.

Dirty the test worktree's root directory, as the test expects.
When testing the untracked-cache, we previously assumed that checking
out master would be sufficient to mark the mtime of the worktree's
root directory as racily-dirty. But sometimes, the checkout would
happen at 12345.999 seconds and the status at 12346.001 seconds,
meaning that the worktree's root directory would not be racily-dirty.
And since it was not truly dirty, occasionally the test would fail.
By making the root truly dirty, the test will always succeed.

df062010 (filter-branch: avoid passing commit message through sed)
introduced a regression when filtering commits with multi-line headers,
if the header contains a blank line. An example of this is a gpg-signed
commit:

tree 3d4038e029712da9fc59a72afbfcc90418451630

-----END PGP SIGNATURE-----
Adding gpg
As a consequence, "filter-branch --msg-filter cat" (which should leave the
commit message unchanged) spills the signature (after the internal blank
line) into the original commit message.
The reason is that although the signature is indented, making the line a
whitespace only line, the "read" call is splitting the line based on
the shell's IFS, which defaults to <space><tab><newline>. The leading
space is consumed and $header_line is empty, causing the "skip header
lines" loop to exit.
The rest of the commit object is then re-used as the rewritten commit
message, causing the new message to include the signature of the
original commit.
Set IFS to an empty string for the "read" call, thus disabling the word
splitting, which causes $header_line to be set to the non-empty value ' '.
This allows the loop to fully consume the header lines before
emitting the original, intact commit message.

When `git clone` is asked to dissociate the repository from the
reference repository whose objects were used, it is quite possible that
the pack files need to be repacked. In that case, the pack files need to
be deleted that were originally hard-links to the reference repository's
pack files.
On platforms where a file cannot be deleted if another process still
holds a handle on it, we therefore need to take pains to release all
pack files and indexes before dissociating.
This fixes https://github.com/git-for-windows/git/issues/446

804098bb (git rebase -i: add static check for commands and SHA-1,
2015-06-29) tried to check all insns before running any in the todo
list, but it did so by implementing its own parser that is a lot
stricter than necessary. We used to allow lines that are indented
(including comment lines), and we used to allow a whitespace between
the insn and the commit object name to be HT, among other things,
that are flagged as an invalid line by mistake.
Fix this by using the same tokenizer that is used to parse the todo
list file in the new check.
Whether it's a good thing to accept indented comments is
debatable (other commands like "git commit" do not accept them), but we
already accepted them in the past, and some people and scripts rely on
this behavior. Also, a line starting with space followed by a '#' cannot
have any meaning other than being a comment, hence it doesn't harm to
accept them as comments.
