receive-pack: convert update hooks to new API
The hook API avoids creating a custom struct child_process and other
internal hook plumbing (e.g. calling find_hook()) and prepares for
the specification of hooks via configs or running parallel hooks.
Execution is still sequential through the run_hooks_opt .jobs == 1,
which is the unchanged default for all hooks.
When use_sideband==1, the async thread redirects the hook outputs to
sideband 2, otherwise it is not used and the hooks write directly to
the fds inherited from the main parent process.
When .jobs == 1, run-command's poll loop is avoided entirely via the
ungroup=1 option like before (this was Jeff's suggestion), achieving
the same real-time output performance.
When running in parallel, run-command with ungroup=0 will capture
and de-interleave the output of each hook, then write to the parent
stderr which is redirected via dup2 to the sideband thread, so that
each parallel hook output is presented clearly to the client.

run-command: poll child input in addition to output
Child input feeding might hit the 100ms output poll timeout as a
side-effect of the ungroup=0 design when feeding multiple children
in parallel and buffering their outputs.
This throttles the write throughput as reported by Kristoffer.
Peff also noted that the parent might block if the write pipe is full
and cause a deadlock if both parent + child wait for one another.
Thus we refactor the run-command I/O loop so it polls on both child
input and output fds to eliminate the risk of artificial 100ms
latencies and unnecessarily blocking the main process.
This ensures that parallel hooks are fed data ASAP while maintaining
responsiveness for (sideband) output.
It's worth noting that in our current design, sequential execution
is not affected by this because it still uses the ungroup=1 behavior,
so there are no run-command induced buffering delays since the child
sequentially outputs directly to the parent-inherited fds.

hook: add jobs option
Allow the API callers to specify the number of jobs across which
hook execution can be parallelized. It defaults to 1 and no hook
currently changes it, so all hooks run sequentially as before.
This allows us to both pave the way for parallel hook execution
(that will be a follow-up patch series building upon this) and to
finish the API conversion of builtin/receive-pack.c, keeping the
output async sideband thread ("muxer") design as Peff suggested.
When .jobs==1 nothing changes, the "copy_to_sideband" async thread
still outputs directly via sideband channel 2, keeping the current
(mostly) real-time output characteristics, avoids unnecessary poll
delays or deadlock risks.
When .jobs > 1, a more complex muxer is needed to buffer the hook
output and avoid interleaving. After working on this mux I quickly
realized I was re-implementing run-command with ungroup=0 so that
idea was dropped in favor of run-command which outputs to stderr.
In other words, run-command itself already can buffer/deinterleave
pp child outputs (ungroup=0), so we can just connect its stderr to
the sideband async task when jobs > 1.
Maybe it helps to illustrate how it works with ascii graphics:

I noticed recently that the leak-checking jobs still take a lot of time,
and upon analysis, the git-svn tests contribute significantly to this.
Analyzing a recent CI run, I saw that the Git test suite contains
1,017 tests, running for approximately 5¼ hours total. Of these, 65
git-svn-related tests (~6% of test count) took 42.24 minutes combined,
accounting for ~13.% of the total runtime. This implies that the git-svn
tests are roughly twice as expernsive compared to the other tests.
However, testing git-svn in the leak-checking jobs provides minimal
value: git-svn is implemented as a Perl script, and leak checking only
handles C code. While git-svn does call into Git's built-in commands
that are implemented in C, these are standard Git operations that are
already thoroughly exercised elsewhere in the test suite. Therefore,
running the git-svn tests in the leak-checking jobs only adds to the
overall run time with little value in return.
Given that the leak-checking jobs are particularly time-intensive and
these 42+ minutes of SVN tests per job provide no additional leak
detection value, skip them in the *-leaks jobs to reduce CI runtime.

t1005: modernize "! test -f" to "test_path_is_missing"
Replace instances of "! test -f <file>" with "test_path_is_missing <file>".
This macro provides better diagnostics when the test fails (it prints
"Path exists:" instead of silently failing).

help: report on whether or not gettext is enabled
When users report that Git has no localized output, we need to check not
only their locale settings, but also whether Git was built with GETTEXT
support in the first place.
Expose this information via the existing build info output by adding a
"gettext: enabled" line to `git version --build-options` (and therefore
also to `git bugreport`) when `NO_GETTEXT` is not defined at build time.

t0610-reftable-basics: mitigate a flaky test on cygwin
Test #29 ('ref transaction: corrupted tables cause failure') started to
fail intermittently for me (from v2.52.0-rc0) when running the testsuite
with '-j8'. (Also, having moved to a new laptop and windows 11, rather
than windows 10). If the test is run by hand, or without any parallelism,
then it passes without issue.
When the test fails (e.g. 1 out of 32 parallel runs) the cause is due to
a permission error while corrupting a table file:
./test-lib.sh: line 1010: .git/reftable/0x000000000001-0x000000000002-d89bb8ee.ref: Permission denied
This corruption is done in a shell loop, directly after a 'test_commit',
which uses an ': >"$f"' expression to truncate the file. Adding a sleep
of one second after the 'test_commit' and before the shell loop fixes
the test (it is not clear why). Replacing the redirection shell expression
with a 'test-tool truncate "$f" 0' invocation also provides a fix, which
could simply be another way to change the timing sufficiently to win the
race.
During a debug session, I tried looking at the strace output for the
shell redirection:
$ rm /tmp/hello; echo hello >/tmp/hello; ls -l /tmp/hello
-rw-r--r-- 1 ramsay None 6 Nov 10 17:25 /tmp/hello
$
When comparing the output, the differences seemed to be what you would
expect and, if anything, the shell redirect probably would have taken
longer than the test-tool solution (many fcntl() calls to dup the stdout
to the <fd>). The call to the win32 api NtCreateFile() was identical,
apart from the first (FileHandle) parameter, of course.
In order to fix this flaky test on cygwin, despite not knowing why it
works, replace the shell redirection with the above 'test-tool truncate'
invocation.

t9700/test.pl: fix path type expectation on cygwin
Commit 4ec7ac101b ("t9700: accommodate for Windows paths", 2025-12-17)
changed the type of the absolute path to the git directory from unix to
win32 for both GfW and cygwin. This fixed the test for GfW but causes
new failures on cygwin, since the test expectation is that it uses unix
paths on cygwin. In order to not break cygwin, disable the new code by
removing the "or $^O eq 'cygwin'" sub-expression from the conditional
part of the fix.

It seems to have caused a few regressions, two of the three known
ones we have proposed solutions for. Let's give ourselves a bit
more room to maneuver during the pre-release freeze period and
restart once the 2.53 ships.
