If a platform lacks the support to specify the dynamic library path,
there is no suitable value to give to the CC_LD_DYNPATH variable.
Allow them to be set to an empty string to signal that they do not
need to add the usual -Wl,-rpath, or -R or whatever option followed
by a directory name. This way,
$(call libpath_template,$(SOMELIBDIR))
would expand to just a single mention of that directory, i.e.
-L$(SOMELIBDIR)
when CC_LD_DYNPATH is set to an empty string (or a "-L", which
would have repeated the same "-L$(SOMELIBDIR)" twice without any
ill effect).

FreeBSD 12 is EOL and no longer available, causing errors in this job.
Upgrade to 13.2, which is the next oldest release with support and that
should keep it for at least another 4 months.
This will be upgraded again once 13.3 is released to avoid further
surprises.
The original report [*] of this problem mentions an error message
"Not enough compute credits to prioritize tasks!". It seems to be
just a reminder that the credit allocate for the Free Tier by Cirrus
is all used up and which might result in additional delays getting a
result.

When we take a library package we depend on (e.g., LIBPCRE) from a
directory other than the default location of the system, we add the
same directory twice on the linker command like, like so:
EXTLIBS += -L$(LIBPCREDIR)/$(lib) $(CC_LD_DYNPATH)$(LIBPCREDIR)/$(lib)
Introduce a template "libpath_template" that takes the path to the
directory, which can be used like so:
EXTLIBS += $(call libpath_template,$(LIBPCREDIR)/$(lib))
and expand it into the "-L$(DIR) $(CC_LD_DYNPATH)$(DIR)" form.
Hopefully we can reduce the chance of typoes this way.

Since c6d3cce6f3 (pipe_command(): handle ENOSPC when writing to a
pipe, 2022-08-17), one `write()` call that results in an `errno` value
`ENOSPC` (which typically indicates out of disk space, which makes
little sense in the context of a pipe) is treated the same as `EAGAIN`.
However, contrary to expectations, as diagnosed in
https://github.com/python/cpython/issues/101881#issuecomment-1428667015,
when writing to a non-blocking pipe on Windows, an `errno` value of
`ENOSPC` means something else: the write _fails_. Completely. Because
more data was provided than the internal pipe buffer can handle.
Somewhat surprising, considering that `write()` is allowed to write less
than the specified amount, e.g. by writing only as much as fits in that
buffer. But it doesn't, it writes no byte at all in that instance.
Let's handle this by manually detecting when an `ENOSPC` indicates that
a pipe's buffer is smaller than what needs to be written, and re-try
using the pipe's buffer size as `size` parameter.
It would be plausible to try writing the entire buffer in a loop,
feeding pipe buffer-sized chunks, but experiments show that trying to
write more than one buffer-sized chunk right after that will immediately
fail because the buffer is unlikely to be drained as fast as `write()`
could write again. And the whole point of a non-blocking pipe is to be
non-blocking.
Which means that the logic that determines the pipe's buffer size
unfortunately has to be run potentially many times when writing large
amounts of data to a non-blocking pipe, as there is no elegant way to
cache that information between `write()` calls. It's the best we can do,
though, so it has to be good enough.
This fix is required to let t3701.60 (handle very large filtered diff)
pass with the MSYS2 runtime provided by the MSYS2 project: Without this
patch, the failed write would result in an infinite loop. This patch is
not required with Git for Windows' variant of the MSYS2 runtime only
because Git for Windows added an ugly work-around specifically to avoid
a hang in that test case.
The diff is slightly chatty because it extends an already-existing
conditional that special-cases a _different_ `errno` value for pipes,
and because this patch needs to account for the fact that
`_get_osfhandle()` potentially overwrites `errno`.

The "disable repository discovery of a bare repository" check,
triggered by setting safe.bareRepository configuration variable to
'explicit', has been loosened to exclude the ".git/" directory inside
a non-bare repository from the check. So you can do "cd .git &&

explicitly specifying $GIT_DIR now.

The beginning of the [System Info] section, which should match the

without tags, for example, "git version unknown.g00000000" can be a
legit version string.

In 1df18a1c9a (reftable: honor core.fsync, 2024-01-23), we have added
code to fsync both newly written reftables as well as "tables.list" to
disk. But there are two code paths where "tables.list" is being written:
- When appending a new table due to a normal ref update.
- When compacting a range of tables during compaction.
We have only addressed the former code path, but do not yet sync the new
"tables.list" file in the latter. Fix this omission.
Note that we are not yet adding any tests. These tests will be added
once the "reftable" backend has been upstreamed.

TEST_PASSES_SANITIZE_LEAK must be set before sourcing test-lib.sh, as we
say in t/README:
GIT_TEST_PASSING_SANITIZE_LEAK=true skips those tests that haven't
declared themselves as leak-free by setting
"TEST_PASSES_SANITIZE_LEAK=true" before sourcing "test-lib.sh". This
test mode is used by the "linux-leaks" CI target.
GIT_TEST_PASSING_SANITIZE_LEAK=check checks that our
"TEST_PASSES_SANITIZE_LEAK=true" markings are current. Rather than
skipping those tests that haven't set "TEST_PASSES_SANITIZE_LEAK=true"
before sourcing "test-lib.sh" this mode runs them with
"--invert-exit-code". This is used to check that there's a one-to-one
mapping between "TEST_PASSES_SANITIZE_LEAK=true" and those tests that
pass under "SANITIZE=leak". This is especially useful when testing a
series that fixes various memory leaks with "git rebase -x".
In a recent commit we fixed a test where it was set after sourcing
test-lib.sh, leading to confusing results.
To prevent future oversights, let's add a simple check to ensure the
value for TEST_PASSES_SANITIZE_LEAK remains unchanged at test_done().
