The documentation of "git whatchanged" is pretty explicit that the
command was retained for historical reasons to help those whose fingers
cannot be retrained. Let's see if they still are finding it hard to
type "git log --raw" instead of "git whatchanged" by marking the
command as "nominated for removal", and require "--i-still-use-this"
on the command line. Adjust the tests so that the option is passed
when we invoke the command. In addition, we test that the command
fails when "--i-still-use-this" is not given.

Some tests on fast-import run "git whatchanged" without even
checking the output from the command. It is tempting to remove the
calls altogether since they are not doing anything useful, but they
presumably were added there while the tests were developed to manually
sanity check which paths were touched.
Replace these calls with "git log --raw", which is a rough
equivalent in the more modern Git.
This does not remove "git whatchanged", but we no longer have to
worry about adjusting these places when we eventually do.

Some documentation examples reference "whatchanged", either as a
placeholder command or an example of source structure.
To reduce the need for future edits when `whatchanged` is removed,
replace these references with alternatives:
- In `MyFirstObjectWalk.adoc`, use `version` as the nearby anchor
point for `walken`, instead of `whatchanged`.
- In `user-manual.adoc`, cite `show` instead of `whatchanged` as
a command whose source lives in the same file as `log`.

Commands slated for removal like "git pack-redundant" now require
an explicit "--i-still-use-this" option to run. This is to
discourage casual use and surface their pending deprecation to
users.
The warning message is long, so factor it into a helper function
you_still_use_that() to simplify reuse by other commands.
Also add a missing test to ensure this enforcement works for
"pack-redundant".

Ever since we issued 2.49, external forces broke our CI jobs in

Make sure outage of third-party sites that supply P4, Git-LFS, and
JGit we use for testing would not prevent our CI jobs from running
at all.
* jc/ci-skip-unavailable-external-software:
ci: skip unavailable external software
The ci/install-dependencies.sh script used in a very early phase of
our CI jobs downloads Perforce, Git-LFS, and JGit, used for running
the test scripts. The test framework is prepared to properly skip
the tests that depend on these external software, but the CI script
is unnecessarily strict (due to its use of "set -e" in ci/lib.sh)
and fails the entire CI run before even starting to test the rest of
the system.
Notice a failure to download to any of these external software, but
keep going. We need to be careful about cleaning after a failed
wget, as a later part of the script that does:
if type jgit >/dev/null 2>&1
then
echo "$(tput setaf 6)JGit Version$(tput sgr0)"
jgit version
else
echo >&2 "WARNING: JGit wasn't installed, see above for clues why"
fi
will (surprise!) succeed running "type jgit", and then fail with
"jgit version", taking the whole thing down due to "set -e".

The image pointed to by the fedora:latest tag has moved from fedora
41 to 42. The fedora 41 container images have awk installed while
the fedora 42 images do not. That change is most likely just part
of reducing the size of the base container images.
In both AlmaLinux and Fedora (as well as other RHEL
derivatives/relatives), awk is provided by the gawk package.
On Fedora, `dnf install awk` would work, by using the package
filelist data to determine that /usr/bin/awk is provided by gawk and
installs gawk as a result.
On AlmaLinux (8 & 9, by quick testing by Todd), that is not the case
and you'd need to use `dnf install gawk` or `dnf install '*bin/awk'`
to get it installed. Having said that, awk _is_ included in the
current AlmaLinux 8 and 9 images, so it isn't strictly needed. But
it's probably better to be explicit that we need it installed, as a
defense against some future change to the AlmaLinux container
removing awk.
Because we know that on both of these distros, our scripts that call
for 'awk' had been using 'gawk' that was installed as part of the
base image, let's make sure that we explicitly install 'gawk'. If
the image already has it, it would be a no-op that does not cause
breakage.

With at least glibc 2.39, glibc provides a function declaration that
matches with this POSIX interface:
int regexec(const regex_t *restrict preg, const char *restrict string,
size_t nmatch, regmatch_t pmatch[restrict], int eflags);
such prototype requires variable-length-array for `pmatch'.
Thus, sparse reports this error:
> ../add-patch.c: note: in included file (through ../git-compat-util.h):
> /usr/include/regex.h:682:41: error: undefined identifier '__nmatch'
> /usr/include/regex.h:682:41: error: bad constant expression type
> /usr/include/regex.h:682:41: error: Variable length array is used.
Note: `__nmatch' is POSIX's nmatch.
The glibc's intention is informing their users to provides a large
enough buffer to hold `__nmatch' results and provides diagnosis if
necessary. It's merely a glibc' implementation detail.
Hide that usage from sparse by using standard C11's macro:

In 3f763ddf28 (fetch: set remote/HEAD if it does not exist, 2024-11-22),
unconditionally adds "HEAD" to the list of ref prefixes we send to the
server.
This breaks a core assumption that the list of prefixes we send to the
server is complete. We must either send all prefixes we care about, or
none at all (in the latter case the server then advertises everything).
The tag following code is careful to only add "refs/tags/" to the list
of prefixes if there are already entries in the prefix list. But because
the new code from 3f763ddf28 runs after the tag code, and because it
unconditionally adds to the prefix list, we may end up with a prefix
list that _should_ have "refs/tags/" in it, but doesn't.
When that is the case, the server does not advertise any tags, and our
auto-following breaks because we never learned about any tags in the
first place.
Fix this by only adding "HEAD" to the ref prefixes when we know that we
are already limiting the advertisement. In either case we'll learn about
HEAD (either through the limited advertisement, or implicitly through a
full advertisement).

When building against zlib-ng, the header file `zlib.h` is not included,
but `zlib-ng.h` is included instead. It's `zlib.h` that defines
`ZLIB_VERSION` and that macro is used to print out zlib version in
`git-version(1)` with `--build-options`. But when it's not defined, no
version is printed.
`zlib-ng.h` defines another macro: `ZLIBNG_VERSION`. Use that macro to
print the zlib-ng version in `git version --build-options` when it's
set. Otherwise fallback to `ZLIB_VERSION`.

In 41f1a8435a (git-compat-util: move include of "compat/zlib.h" into
"git-zlib.h", 2025-01-28) some code was refactored to enable easier
linking against zlib-ng.
This removed `zlib.h` being indirectly included in `help.c`. As this
file uses `ZLIB_VERSION` to print the version number of zlib when
running git-version(1) with `--build-options`, this resulted in a
regression.
Include `git-zlib.h` directly into `help.c` to print zlib version
information. This brings back the zlib version in the output of
`git version --build-options`.

Hotfix to help building Git-for-Windows.
* js/win-2.49-build-fixes:
cmake: generalize the handling of the `CLAR_TEST_OBJS` list
meson: fix sorting
ident: stop assuming that `gw_gecos` is writable
Some future breaking changes would remove certain parts of the
default repository, which were still described even when the

* pw/repo-layout-doc-update:
docs: fix repository-layout when building with breaking changes
A late-comer to the v2.49.0 party, `sk/unit-test-oid`, added yet another
array item to `CLAR_TEST_OBJS`, causing the `win+VS build` job to fail
with symptoms like this one:
unit-tests-lib.lib(u-oid-array.obj) : error LNK2019: unresolved
external symbol cl_parse_any_oid referenced in function fill_array
This is a similar scenario to the one that forced me to write
8afda42fce (cmake: generalize the handling of the `UNIT_TEST_OBJS`
list, 2024-09-18): The hard-coded echo of `CLAR_TEST_OBJS` in
`CMakeLists.txt` that recapitulates faithfully what was already
hard-coded in `Makefile` would either have to be updated whack-a-mole
style, or generalized.
Just like I chose the latter option for `UNIT_TEST_OBJS`, I now do the
same for `CLAR_TEST_OBJS`.

In 590e081dea (ident: add NO_GECOS_IN_PWENT for systems without
pw_gecos in struct passwd, 2011-05-19), code was introduced to iterate
over the `gw_gecos` field; The loop variable is of type `char *`, which
assumes that `gw_gecos` is writable.
However, it is not necessarily writable (and it is a bad idea to have it
writable in the first place), so let's switch the loop variable type to
`const char *`.
This is not a new problem, but what is new is the Meson build. While it
does not trigger in CI builds, imitating the commands of
`ci/run-build-and-tests.sh` in a regular Git for Windows SDK (`meson
setup build . --fatal-meson-warnings --warnlevel 2 --werror --wrap-mode
nofallback -Dfuzzers=true` followed by `meson compile -C build --`
results in this beautiful error:
"cc" [...] -o libgit.a.p/ident.c.obj "-c" ../ident.c
../ident.c: In function 'copy_gecos':
../ident.c:68:18: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
68 | for (src = get_gecos(w); *src && *src != ','; src++) {
| ^
cc1.exe: all warnings being treated as errors
Now, why does this not trigger in CI? The answer is as simple as it is
puzzling: The `win+Meson` job completely side-steps Git for Windows'
development environment, opting instead to use the GCC that is on the
`PATH` in GitHub-hosted `windows-latest` runners. That GCC is pinned to
v12.2.0 and targets the UCRT (unlikely to change any time soon, see
https://github.com/actions/runner-images/blob/win25/20250303.1/images/windows/toolsets/toolset-2022.json#L132-L141).
That is in stark contrast to Git for Windows, which uses GCC v14.2.0 and
targets MSVCRT. Git for Windows' `Makefile`-based build also obviously
uses different compiler flags, otherwise this compile error would have
had plenty of opportunity in almost 14 years to surface.
In other words, contrary to my expectations, the `win+Meson` job is
ill-equipped to replace the `win build` job because it exercises a
completely different tool version/compiler flags vector than what Git
for Windows needs.
Nevertheless, there is currently this huge push, including breaking
changes after -rc1 and all, for switching to Meson. Therefore, we need
to make it work, somehow, even in Git for Windows' SDK, hence this
patch, at this point in time.
