ad228c24df replay: drop rev-list formatting options from manual
The rev-list options in our manuals are quite long; git-replay's manual
is no exception. Since replay doesn't use the formatting options at all
(it has its own output format), drop them.

This is the first time we have needed compound tests [1] for if[n]def in
our documentation:

    git grep '^ifn\?def::' Documentation | grep '[,+]'

[1]: https://docs.asciidoctor.org/asciidoc/latest/directives/ifdef-ifndef/

For both ifdef and ifndef, the "," takes on the intuitive meaning:
- ifdef: if any of the listed attributes are set…
- ifndef: unless any of the listed attributes are set

(Use "+" for "all".)

d79fff4a11 remote: always allocate branch.push_tracking_ref
In branch_get_push(), we usually allocate a new string for the @{push}
ref, but will not do so in push.default=upstream mode, where we just
pass back the result of branch_get_upstream() directly.

This led to a hacky memory management scheme in e291c75a95 (remote.c:
add branch_get_push, 2015-05-21): we store the result in the
push_tracking_ref field of a "struct branch", under the assumption that
the branch struct will last until the end of the program. So even though
the struct doesn't know if it has an allocated string or not, it doesn't
matter because we hold on to it either way.

But that assumption was violated by f5ccb535cc (remote: fix leaking
config strings, 2024-08-22), which added a function to free branch
structs. Any struct which is fed to branch_release() is at risk of
leaking its push_tracking_ref member.

I don't think this can actually be triggered in practice. We rarely
actually free the branch structs, and we only fill in the
push_tracking_ref string lazily when it is needed. So triggering the
leak would require a code path that does both, and I couldn't find one.

Still, this is an ugly trap that may eventually spring on us. Since
there is only one code path in branch_get_push() that doesn't allocate,
let's just have it copy the string. And then we know that
push_tracking_ref is always allocated, and we can free it in
branch_release().

9bf9eed093 remote: fix leak in branch_get_push_1() with invalid "simple" config
Most of the code paths in branch_get_push_1() allocate a string for the
@{push} value. We then return the result, which is stored in a "struct
branch", so the value is not leaked.

But there's one path that does leak: when we are in the "simple" push
mode, we have to check that the @{push} value matches what we'd get for
@{upstream}. If it doesn't, we return an error, but forget to free the
@{push} value we computed.

Curiously, the existing tests don't trigger this with LSan, even though
they do exercise the code path. As far as I can tell, it should be
triggered via:

  git -c push.default=simple \
      -c branch.foo.remote=origin \
      -c branch.foo.merge=refs/heads/not-foo \
      rev-parse foo@{push}

which will complain that the upstream ("not-foo") does not match the
push destination ("foo"). We do die() shortly after this, but not until
after returning from branch_get_push_1(), which is where the leak
happens.

So it seems like a false negative in LSan. However, I can trigger it
reliably by printing the @{push} value using for-each-ref. This takes a
little more setup (because we need "foo" to actually exist to iterate
over it with for-each-ref), but we can piggy-back on the existing repo
config in t6300.

782a719e99 remote: drop const return of tracking_for_push_dest()
The string returned from tracking_for_push_dest() comes from
apply_refspec(), and thus is always an allocated string (or NULL). We
should return a non-const pointer so that the caller knows that
ownership of the string is being transferred.

This goes back to the function's origin in e291c75a95 (remote.c: add
branch_get_push, 2015-05-21). It never really mattered because our
return is just forwarded through branch_get_push_1(), which returns a
const string as part of an intentionally hacky memory management scheme
(see that commit for details).

As the first step of untangling that hackery, let's drop the extra const
from this helper function (and from the variables that store its
result). There should be no functional change (yet).

9500b2131d remote: return non-const pointer from error_buf()
We have an error_buf() helper that functions a bit like our error()
helper, but returns NULL instead of -1. Its return type is "const char
*", but this is overly restrictive. If we use the helper in a function
that returns non-const "char *", the compiler will complain about
the implicit cast from const to non-const.

Meanwhile, the const in the helper is doing nothing useful, as it only
ever returns NULL. Let's drop the const, which will let us use it in
both types of function.

d7971544fe ci(*-leaks): skip the git-svn tests to save time
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.

59da9f292a 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
  $

  $ strace -o zzz bash -c ': >/tmp/hello'
  $

Similarly, for the test-tool solution:

  $ strace -o xxx ./t/helper/test-tool truncate /tmp/hello 0
  $

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.

c381a21490 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.
