It was largely replaced by fnmatch_icase_mem() and its last use was in
84b8b5d (remove match_pathspec() in favor of match_pathspec_depth() -

Some multi-byte encoding can have a backslash byte as a later part
of one letter, which would confuse "highlight" filter used in
gitweb.

Some multi-byte character encodings (such as Shift_JIS and GBK) have
characters whose final bytes is an ASCII '\' (0x5c), and they
will be displayed as funny-characters even if $fallback_encoding is
correct. This is because `highlight` command always expects UTF-8
encoded strings from STDIN.
$ echo 'my $v = "申";' | highlight --syntax perl | w3m -T text/html -dump
my $v = "申";
$ echo 'my $v = "申";' | iconv -f UTF-8 -t Shift_JIS | highlight \
--syntax perl | iconv -f Shift_JIS -t UTF-8 | w3m -T text/html -dump
iconv: (stdin):9:135: cannot convert
my $v = "
This patch prepare git blob objects to be encoded into UTF-8 before
highlighting in the manner of `to_utf8` subroutine.

The last test added to 't5510-fetch' in 0898c9628104 (fetch: release
pack files before garbage-collecting, 2016-01-13) may sporadically
trigger following error message from the test harness:
rm: cannot remove 'trash directory.t5510-fetch/auto-gc/.git': Directory not empty
The test in question forces an auto-gc, which, if the system supports
it, runs in the background by default, and occasionally takes long
enough for the test to finish and for 'test_done' to start
housekeeping. This can lead to the test's 'git gc --auto' in the
background and 'test_done's 'rm -rf $trash' in the foreground racing
each other to create and delete files and directories. It might just
happen that 'git gc' re-creates a directory that 'rm -rf' already
visited and removed, which ultimately triggers the above error.
Disable detaching the auto-gc process to ensure that it finishes
before the test can continue, thus avoiding this racy situation.

Git LFS 1.2.0 removed a preamble from the output of the 'git lfs pointer'
command [1] which broke the parsing of this output. Adjust the parser
to support the old and the new format.
Please note that this patch slightly changes the second return parameter
from a list of LF terminated strings to a single string that contains
a number of LF characters.

The Git Travis CI OSX build always installs the latest versions of Git LFS and
Perforce via brew and the Linux build installs fixed versions. Consequently new
LFS/Perforce versions can break the OS X build even if there is no change in
Git.

0492eb48 (t9824: fix broken &&-chain in a subshell, 2016-04-24)
revealed a test that was broken from the beginning, as it expected a
wrong size. The expected size of the file under test is 39
bytes. The test checked that the size is 13 bytes, but this was not
noticed because it was breaking the &&-chain.
Fix the reference value to make the test pass.

On Windows, we have to emulate the fstat() call to fill out information
that takes extra effort to obtain, such as the file permissions/type.
If all we want is the file size, we can use the much cheaper
GetFileSizeEx() function (available since Windows XP).

Often we are mmap()ing read-only. In those cases, it is wasteful to map in
copy-on-write mode. Even worse: it can cause errors where we run out of
space in the page file.
So let's be extra careful to map files in read-only mode whenever
possible.

It is not really helpful when a `git fetch` fails with the message:
fatal: mmap failed: No error
In the particular instance encountered by a colleague of yours truly,
the Win32 error code was ERROR_COMMITMENT_LIMIT which means that the
page file is not big enough.
Let's make the message
fatal: mmap failed: File too large
instead, which is only marginally better, but which can be associated
with the appropriate work-around: setting `core.packedGitWindowSize` to
a relatively small value.

In f924b52 (Windows: add pthread_sigmask() that does nothing,
2016-05-01), we introduced a no-op for Windows. However, this breaks
building Git in Git for Windows' SDK because pthread_sigmask() is
already a no-op there, #define'd in the pthread_signal.h header in
/mingw64/x86_64-w64-mingw32/include/.
Let's wrap the definition of pthread_sigmask() in a guard that skips
it when compiling with MinGW-w64' headers.

are similar to POSIX signals, just ignore the request to block the signal.
In the particular case, the effect of blocking SIGPIPE on POSIX is that
write() calls return EPIPE when the reader closes the pipe. This is how
write() behaves on Windows.

These were added by 8bf4bec (add "ok=sigpipe" to
test_must_fail and use it to fix flaky tests, 2015-11-27)
because we would racily die via SIGPIPE when the pack was
rejected by the other side.
But since we have recently de-flaked send-pack, we should be
able to tighten up these tests (including re-adding the
expected output checks).

In commit 9ff18fa (fetch-pack: ignore SIGPIPE in sideband
demuxer, 2016-02-24), we started using sigchain_push() to
ignore SIGPIPE in the async demuxer thread. However, this is
rather clumsy, as it ignores SIGPIPE for the entire process,
including the main thread. At the time we didn't have any
per-thread signal support, but we now we do. Let's use it.

If we get an error from pack-objects, we may exit
send_pack() early, before reading the server's status
response. In such a case, we may racily see SIGPIPE from our
async demuxer (which is trying to write that status back to
us), and we'd prefer to continue pushing the error up the
call stack, rather than taking down the whole process with
signal death.
This is safe to do because our demuxer just calls
recv_sideband, whose data writes are all done with
write_or_die(), which will notice SIGPIPE.
We do also write sideband 2 to stderr, and we would no
longer die on SIGPIPE there (if it were piped in the first
place, and if the piped program went away). But that's
probably a good thing, as it likewise should not abort the
push process at all (neither immediately by signal, nor
eventually by reporting failure back to the main thread).

Async processes can be implemented as separate forked
processes, or as threads (depending on the NO_PTHREADS
setting). In the latter case, if an async thread gets
SIGPIPE, it takes down the whole process. This is obviously
bad if the main process was not otherwise going to die, but
even if we were going to die, it means the main process does
not have a chance to report a useful error message.
There's also the small matter that forked async processes
will not take the main process down on a signal, meaning git
will behave differently depending on the NO_PTHREADS
setting.
This patch fixes it by adding a new flag to "struct async"
to block SIGPIPE just in the async thread. In theory, this
should always be on (which makes async threads behave more
like async processes), but we would first want to make sure
that each async process we spawn is careful about checking
return codes from write() and would not spew endlessly into
a dead pipe. So let's start with it as optional, and we can
enable it for specific sites in future patches.
The natural name for this option would be "ignore_sigpipe",
since that's what it does for the threaded case. But since
that name might imply that we are ignoring it in all cases
(including the separate-process one), let's call it
"isolate_sigpipe". What we are really asking for is
isolation. I.e., not to have our main process taken down by
signals spawned by the async process. How that is
implemented is up to the run-command code.

This fixes a deadlock on the client side when pushing a
large number of refs from a corrupted repo. There's a
reproduction script below, but let's start with a
human-readable explanation.
The client side of a push goes something like this:
1. Start an async process to demux sideband coming from
the server.
2. Run pack-objects to send the actual pack, and wait for
its status via finish_command().
3. If pack-objects failed, abort immediately.
4. If pack-objects succeeded, read the per-ref status from
the server, which is actually coming over a pipe from
the demux process started in step 1.
We run finish_async() to wait for and clean up the demux
process in two places. In step 3, if we see an error, we
want it to end early. And after step 4, it should be done
writing any data and we are just cleaning it up.
Let's focus on the error case first. We hand the output
descriptor to the server over to pack-objects. So by the
time it has returned an error to us, it has closed the
descriptor and the server has gotten EOF. The server will
mark all refs as failed with "unpacker error" and send us
back the status for each (followed by EOF).
This status goes to the demuxer thread, which relays it over
a pipe to the main thread. But the main thread never even
tries reading the status. It's trying to bail because of the
pack-objects error, and is waiting for the demuxer thread to
finish. If there are a small number of refs, that's OK; the
demuxer thread writes into the pipe buffer, sees EOF from
the server, and quits. But if there are a large number of
refs, it may block on write() back to the main thread,
leading to a deadlock (the main thread is waiting for the
demuxer to finish, the demuxer is waiting for the main
thread to read).
We can break this deadlock by closing the pipe between the
demuxer and the main thread before calling finish_async().
Then the demuxer gets a write() error and exits.
The non-error case usually just works, because we will have
read all of the data from the other side. We do close
demux.out already, but we only do so _after_ calling
finish_async(). This is OK because there shouldn't be any
more data coming from the server. But technically we've only
read to a flush packet, and a broken or malicious server
could be sending more cruft. In such a case, we would hit
the same deadlock. Closing the pipe first doesn't affect the
normal case, and means that for a cruft-sending server,
we'll notice a write() error rather than deadlocking.
Note that when write() sees this error, we'll actually
deliver SIGPIPE to the thread, which will take down the
whole process (unless we're compiled with NO_PTHREADS). This
isn't ideal, but it's an improvement over the status quo,
which is deadlocking. And SIGPIPE handling in async threads
is a bigger problem that we can deal with separately.
A simple reproduction for the error case is below. It's
technically racy (we could exit the main process and take
down the async thread with us before it even reads the
status), though in practice it seems to fail pretty
consistently.
git init repo &&
cd repo &&
# make some commits; we need two so we can simulate corruption
# in the history later.
git commit --allow-empty -m one &&
one=$(git rev-parse HEAD) &&
git commit --allow-empty -m two &&
two=$(git rev-parse HEAD) &&
# now make a ton of refs; our goal here is to overflow the pipe buffer
# when reporting the ref status, which will cause the demuxer to block
# on write()
for i in $(seq 20000); do
echo "create refs/heads/this-is-a-really-long-branch-name-$i $two"
done |
git update-ref --stdin &&
# now make a corruption in the history such that pack-objects will fail
rm -vf .git/objects/$(echo $one | sed 's}..}&/}') &&
# and then push the result
git init --bare dst.git &&
git push --mirror dst.git

When directories are moved using `git mv` all files in the directory
have been just moved, but no further action was taken on them. This
was done by assigning the mode = WORKING_DIRECTORY to the files
inside a moved directory.
submodules however need to update their link to the git directory as
well as updates to the .gitmodules file. By removing the condition of
`mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for
the required submodule actions, we perform these for submodules in a
moved directory.

The "user.useConfigOnly" configuration variable makes it an error
if users do not explicitly set user.name and user.email. However,
its check was not done early enough and allowed another error to
trigger, reporting that the default value we guessed from the
system setting was unusable. This was a suboptimal end-user
experience as we want the users to set user.name/user.email without
relying on the auto-detection at all.

The env_hint message applies perfectly to the case when
user.useConfigOnly is set and at least one of the user.name and the
user.email are not provided.
Additionally, use a less descriptive error message to discourage
users from disabling user.useConfigOnly configuration variable to
work around this error condition. We want to encourage them to set
user.name or user.email instead.

If user.useConfigOnly is set, it does not make sense to try to
auto-detect the name and/or the email. The auto-detection may
even result in a bogus name and trigger an error message.
Check if the use-config-only is set and die if no explicit name was
given, before attempting to auto-detect, to correct this.

The time_in_seconds script should use $PYTHON_PATH, rather than
just hard-coded python, so that users can override which version

Update the git-p4 tests so that they work with both
Python2 and Python3.
We have to be explicit about the difference between
Unicode text strings (Python3 default) and raw binary
strings which will be exchanged with Perforce.
Additionally, print always takes parentheses in Python3.

The python one-liner for getting the current time prints out
error messages if the current directory is deleted while it is
running if using python3.
Avoid these messages by switching to "/" before running it.
This problem does not arise if using python2.

recurses into, but this was incorrect when the command was not run
from the root level of the superproject.

This patch is just a test and fixes no bug as there is currently no bug
in the path handling of `submodule update`.
In `submodule update` we make a call to `submodule--helper list --prefix
"$wt_prefix"` which looks a bit brittle and likely to introduce a bug
for the path handling. It is not a bug as the prefix is ignored inside
the submodule helper for now. If this test breaks eventually, we want
to make sure the `wt_prefix` is passed correctly into recursive submodules.
Hint: In recursive submodules we expect `wt_prefix` to be empty.

The path code in question:
displaypath=$(relative_path "$prefix$sm_path")
prefix=$displaypath
if recursive:
eval cmd_status
That way we change `prefix` each iteration to contain another
'../', because of the the relative_path computation is done
on an already computed relative path.
We must call relative_path exactly once with `wt_prefix` non empty.
Further calls in recursive instances to to calculate the displaypath
already incorporate the correct prefix from before. Fix the issue by
clearing `wt_prefix` in recursive calls.

When calling `git submodule init` from a recursive instance of
`git submodule update --recursive`, the reported path is wrong as it
skips the nested submodules.
The new test demonstrates a failure in the code prior to this patch.
Instead of getting the expected
Submodule 'submodule' (${pwd}/submodule) registered for path '../super/submodule'
the `super` directory is omitted and you get
Submodule 'submodule' (${pwd}/submodule) registered for path '../submodule'
instead.

The `prefix` was put in front of the display path unconditionally.
This is wrong as any relative path computation would need to be at
the front, so include the prefix into the display path.
The new test replicates the previous test with the difference of executing
from a sub directory. By executing from a sub directory all we would
expect all displayed paths to be prefixed by '../'.
Prior to this patch the test would report
Entering 'nested1/nested2/../nested3'
instead of the expected
Entering '../nested1/nested2/nested3'

Use SSLv23_method always and disable SSL if needed.
TLSv1_method() function is deprecated in OpenSSL 1.1.0 and the compiler
emits a warning.
SSLv23_method() is also deprecated, but the alternative, TLS_method(),
is new in OpenSSL 1.1.0 so requires checking by configure. Stick to
SSLv23_method() for now (this is aliased to TLS_method()).
