Per [1] and the warnings our CI is emitting GitHub is phasing in
"macos-12" as their "macos-latest".
As with [2], let's pin our image to a specific version so that we're
not having it swept from under us, and our upgrade cycle can be more
predictable than whenever GitHub changes their images.

Work around older clang that warns against C99 zero initialization

config.mak.dev: disable suggest braces error on old clang versions

Add the "-Wno-missing-braces" option when building with an old version
of clang to suppress the "suggest braces around initialization" error
in developer mode.
For example, using an old version of clang gives the following errors
(when in DEVELOPER=1 mode):
$ make builtin/merge-file.o
CC builtin/merge-file.o
builtin/merge-file.c:29:23: error: suggest braces around initialization \
of subobject [-Werror,-Wmissing-braces]
mmfile_t mmfs[3] = { 0 };
^
{}
builtin/merge-file.c:31:20: error: suggest braces around initialization \
of subobject [-Werror,-Wmissing-braces]
xmparam_t xmp = { 0 };
^
{}
2 errors generated.
This example compiles without error/warning with updated versions of
clang. Since this is an obsolete error, use the -Wno-missing-braces
option to silence the warning when using an older compiler. This
avoids the need to update the code to use "{{0}}" style
initializations.
Upstream clang version 8 has the problem. It was fixed in version 9.
The version of clang distributed by Apple with XCode has its own
unique set of version numbers. Apple clang version 11 has the
problem. It was fixed in version 12.

When the repository does not yet have commits, some errors describe that
there is no branch:
$ git init -b first
$ git branch --edit-description first
error: No branch named 'first'.
$ git branch --set-upstream-to=upstream
fatal: branch 'first' does not exist
$ git branch -c second
error: refname refs/heads/first not found
fatal: Branch copy failed
That "first" branch is unborn but to say it doesn't exists is confusing.
Options "-c" (copy) and "-m" (rename) show the same error when the
origin branch doesn't exists:
$ git branch -c non-existent-branch second
error: refname refs/heads/non-existent-branch not found
fatal: Branch copy failed
$ git branch -m non-existent-branch second
error: refname refs/heads/non-existent-branch not found
fatal: Branch rename failed
Note that "--edit-description" without an explicit argument is already
considering the _empty repository_ circumstance in its error. Also note
that "-m" on the initial branch it is an allowed operation.
Make the error descriptions for those branch operations with unborn or
non-existent branches, more informative.
This is the result of the change:
$ git init -b first
$ git branch --edit-description first
error: No commit on branch 'first' yet.
$ git branch --set-upstream-to=upstream
fatal: No commit on branch 'first' yet.
$ git branch -c second
fatal: No commit on branch 'first' yet.
$ git branch [-c/-m] non-existent-branch second
fatal: No branch named 'non-existent-branch'.

In the tmp-objdir api, tmp_objdir_create will create a temporary
directory but also register signal handlers responsible for removing
the directory's contents and the directory itself. However, the
function responsible for recursively removing the contents and
directory, remove_dir_recurse() calls opendir(3) and closedir(3).
This can be problematic because these functions allocate and free
memory, which are not async-signal-safe functions. This can lead to
deadlocks.
One place we call tmp_objdir_create() is in git-receive-pack, where
we create a temporary quarantine directory "incoming". Incoming
objects will be written to this directory before they get moved to
the object directory.
We have observed this code leading to a deadlock:

Since we can't do the cleanup in a portable and signal-safe way, skip
the cleanup when we're handling a signal.
This means that when signal handling, the temporary directory may not
get cleaned up properly. This is mitigated by b3cecf49ea (tmp-objdir: new
API for creating temporary writable databases, 2021-12-06) which changed
the default name and allows gc to clean up these temporary directories.
In the event of a normal exit, we should still be cleaning up via the
atexit() handler.

"git" built with RUNTIME_PREFIX flag turned on could figure out
gitexecdir and other paths as relative to "git" executable.
However, in the section specifies gitexecdir, RUNTIME_PREFIX wasn't
mentioned, thus users may wrongly assume that "git" always locates
gitexecdir as relative path to the executable.
Let's clarify that only "git" built with RUNTIME_PREFIX will locate
gitexecdir as relative path.

While GCC 4.5 is already 12 years old, git checks for even older

a small and simple fix is readily available.

Apply similar treatment with respect to cruft packs as in a few commits
ago to `repack` with a non-zero `--batch-size`.
Since the case of a non-zero `--batch-size` is handled separately (in
`fill_included_packs_batch()` instead of `fill_included_packs_all()`), a
separate fix must be applied for this case.

The fill_included_packs_batch() routine is responsible for aggregating
objects in packs with a non-zero value for the `--batch-size` option of
the `git multi-pack-index repack` sub-command.
Since this routine is explicitly called only when `--batch-size` is
non-zero, there is no point in checking that this is the case in our
loop condition.
Remove the unnecessary part of this condition to avoid confusion.

Replace a direct invocation of Git's `xcalloc()` wrapper with the
`CALLOC_ARRAY()` macro instead.
The latter is preferred since it is more conventional in Git's codebase,
but also because it automatically picks the correct value for the record
size.

The `repack` sub-command of the `git multi-pack-index` builtin creates a
new pack aggregating smaller packs contained in the MIDX up to some
given `--batch-size`.
When `--batch-size=0`, this instructs the MIDX builtin to repack
everything contained in the MIDX into a single pack.
In similar spirit as a previous commit, it is undesirable to repack the
contents of a cruft pack in this step. Teach `repack` to ignore any
cruft pack(s) when `--batch-size=0` for the same reason(s).
(The case of a non-zero `--batch-size` will be handled in a subsequent
commit).

The `expire` sub-command unlinks any packs that are (a) contained in the
MIDX, but (b) have no objects referenced by the MIDX.
This sub-command ignores `.keep` packs, which remain on-disk even if
they have no objects referenced by the MIDX. Cruft packs, however,
aren't given the same treatment: if none of the objects contained in the
cruft pack are selected from the cruft pack by the MIDX, then the cruft
pack is eligible to be expired.
This is less than desireable, since the cruft pack has important
metadata about the individual object mtimes, which is useful to
determine how quickly an object should age out of the repository when
pruning.
Ordinarily, we wouldn't expect the contents of a cruft pack to
duplicated across non-cruft packs (and we'd expect to see the MIDX
select all cruft objects from other sources even less often). But
nonetheless, it is still possible to trick the `expire` sub-command into
removing the `.mtimes` file in this circumstance.
Teach the `expire` sub-command to ignore cruft packs in the same manner
as it does `.keep` packs, in order to keep their metadata around, even
when they are unreferenced by the MIDX.

The `expire` sub-command of `git multi-pack-index` will never expire
`.keep` packs, regardless of whether or not any of their objects were
selected in the MIDX.
This has always been the case since 19575c7c8e (multi-pack-index:

(multi-pack-index: prepare for 'expire' subcommand, 2019-06-10), when

In 2708ce62d2 (branch: sort detached HEAD based on a flag, 2021-01-07) a
call to wt_status_state_free_buffers, responsible of freeing the
resources that could be allocated in the local struct wt_status_state
state, was eliminated.
The call to wt_status_state_free_buffers was introduced in 962dd7ebc3
(wt-status: introduce wt_status_state_free_buffers(), 2020-09-27). This
commit brings back that call in get_head_description.

This uses atoi() and checks if the result is not zero to decide what
to do. Turning it into the usual Boolean environment variable to
use git_env_bool() would not break those who have been using "set to
0, or set to non-zero, that can be parsed with atoi()" values, but
will match the expectation of those who expected "true" to mean
"yes".

Many environment variables use the git_env_bool() API to parse their
values, and allow the usual "true/yes/on are true, false/no/off are
false. In addition non-zero numbers are true and zero is false. An
empty string is also false." set of values.
Mark them as such, and consistently say "true" or "false", instead
of random mixes of '1', '0', 'yes', 'true', etc. in their
description.

Even though the name of the environment variable is mentioned in
"git config --help" from http.sslVerify, there is no description for
it. Add one.
Note that this is not a usual Boolean environment variable whose
value can be yes/true/on vs no/false/off; the existence of it is
enough to trigger the feature named by the variable.

Since its inception in d0bfd026a8 (Add basic infrastructure to assign
attributes to paths, 2007-04-12), the attribute code carries a little
bit of debug code that is conditionally compiled only when DEBUG_ATTR is
set. But since you have to know about it and make a special build of Git
to use it, it's not clear that it's helping anyone (and there are very
few mentions of it on the list over the years).
Meanwhile, it causes slight headaches. Since it's not built as part of a
regular compile, it's subject to bitrot. E.g., this was dealt with in
712efb1a42 (attr: make it build with DEBUG_ATTR again, 2013-01-15), and
it currently fails to build with DEVELOPER=1 since e810e06357 (attr:
tighten const correctness with git_attr and match_attr, 2017-01-27).
And it causes confusion with -Wunused-parameter; the "what" parameter of
fill_one() is unused in a normal build, but needed in a debug build.
Let's just get rid of this code (and the now-useless parameter).

The callback function for --trailer writes directly to the global
trailer_args and ignores opt->value completely. This is OK, since that's
where we expect to find the value. But it does mean the option
declaration isn't as clear. E.g., we have:
OPT_BOOL(0, "reset-author", &renew_authorship, ...),
OPT_CALLBACK_F(0, "trailer", NULL, ..., opt_pass_trailer)
In the first one we can see where the result will be stored, but in the
second, we get only NULL, and you have to go read the callback.
Let's pass &trailer_args, and use it in the callback. As a bonus, this
silences a -Wunused-parameter warning.

We declare the --object-dir option like:
OPT_CALLBACK(0, "object-dir", &opts.object_dir, ...);
but the pointer to opts.object_dir is completely unused. Instead, the
callback writes directly to a global. Which fortunately happens to be
opts.object_dir. So everything works as expected, but it's unnecessarily
confusing.
Instead, let's have the callback write to the option value pointer that
has been passed in. This also quiets a -Wunused-parameter warning (since
we don't otherwise look at "opt").

The resolve_relative_url() function takes argc and argv parameters; it
then reads up to 3 elements of argv without looking at argc at all. At
first glance, this seems like a bug. But it has only one caller,
cmd__submodule_resolve_relative_url(), which does confirm that argc is
3.
The main reason this is a separate function is that it was moved from
library code in 96a28a9bc6 (submodule--helper: move
"resolve-relative-url-test" to a test-tool, 2022-09-01).
We can make this code simpler and more obviously safe by just inlining
the function in its caller. As a bonus, this silences a
-Wunused-parameter warning.
