Since 982288e9bd (status: rebase and merge can be in progress at the
same time, 2018-11-12), when a merge is in progress as part of a 'git
rebase -r' operation, 'wt_longstatus_print_state' shows information
about the in-progress rebase (via show_rebase_information), and then
calls 'show_merge_in_progress' to help the user conclude the merge. This
function suggests using 'git commit' to do so, but this throws away the
authorship information from the original merge, which is not ideal.
Using 'git rebase --continue' instead preserves the authorship
information, since we enter 'sequencer.c:run_git_commit' which calls
read_env_script to read the author-script file.
Note however that this only works when a merge was scheduled using a
'merge' instruction in the rebase todo list. Indeed, when using 'exec
git merge', the state files necessary for 'git rebase --continue' are
not present, and one must use 'git commit' (or 'git merge --continue')
in that case.
Be more helpful to the user by suggesting either 'git rebase
--continue', when the merge was scheduled using a 'merge' instruction,
and 'git commit' otherwise. As such, add a
'merge_during_rebase_in_progress' field to 'struct wt_status_state', and
detect this situation in wt_status_check_rebase by looking at the last
command done. Adjust wt_longstatus_print_state to check this field and
suggest 'git rebase --continue' if a merge came from a 'merge'
instruction, by calling show_rebase_in_progress directly.
Add two tests for the new behaviour, using 'merge' and 'exec git merge'
instructions.

When "git status" is invoked during a rebase, we print the last commands
done and the next commands to do, and abbreviate commit hashes found in
those lines. However, we only abbreviate hashes in 'pick', 'squash' and
plain 'fixup' lines, not those in 'merge -C' and 'fixup -C' lines, as
the parsing done in wt-status.c::abbrev_oid_in_line is not prepared for
such lines.
Improve the parsing done by this function by special casing 'fixup' and
'merge' such that the hash to abbreviate is the string found in the
third field of 'split', instead of the second one for other commands.
Introduce a 'hash' strbuf pointer to point to the correct field in all
cases.

When a user runs 'git rebase --continue' to conclude a conflicted merge
during a 'git rebase -r' invocation, we do not create a merge commit if
the resolution was empty (i.e. if the index and HEAD are identical). We
simply continue the rebase as if no 'merge' instruction had been given.
This is confusing since all commits from the side branch are absent from
the rebased history. What's more, if that 'merge' is the last
instruction in the todo list, we fail to remove the merge state, such
that running 'git status' shows we are still merging after the rebase
has concluded.
This happens because in 'sequencer.c::commit_staged_changes', we exit
early before calling 'run_git_commit' if 'is_clean' is true, i.e. if
nothing is staged. Fix this by also checking for the presence of
MERGE_HEAD before exiting early, such that we do call 'run_git_commit'
when MERGE_HEAD is present. This also ensures that we unlink
git_path_merge_head later in 'commit_staged_changes' to clear the merge
state.
Make sure to also remove MERGE_HEAD when a merge command fails to start.
We already remove MERGE_MSG since e032abd5a0 (rebase: fix rewritten list
for failed pick, 2023-09-06). Removing MERGE_HEAD ensures that in this
situation, upon 'git rebase --continue' we still exit early in
'commit_staged_changes', without calling 'run_git_commit'. This is
already covered by t5407.11, which fails without this change because we
enter 'run_git_commit' and then fail to find 'rebase_path_message'.

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`.

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`.

be sorted alphabetically, but there is one mistake. Let's fix that.

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.
