220adb16e4 config.mak.uname: remove unused uname_P variable
The uname_P make variable was added in commit e15f545155 ("Makefile
tweaks: Solaris 9+ dont need iconv / move up uname variables",
2006-02-20), but it seems to never have been used (even in that original
commit). The man page for 'uname' notes that the '-p' processor option
is non-portable (the 'uname_M' variable is used by the Makefile for that
purpose).

Remove the unused 'uname_P' make variable.

f78e2dd88a Makefile: drop -Wno-universal-initializer from SP_EXTRA_FLAGS
Commit 1c96642326 ("sparse: allow '{ 0 }' to be used without warnings",
2020-05-22) added -Wno-universal-initializer to the SP_EXTRA_FLAGS in
order to suppress potential sparse warnings from using '{0}' as an
aggregate initializer. At that time, the default was for sparse to
issue warnings (i.e. the default was -Wuniversal-initializer) if such
an initializer was used to initialize an aggregate whose first member
was a pointer type. However, this default was changed just a few days
later to -Wno-universal-initializer (first released in sparse v0.6.2)
and has been so in all subsequent release versions of sparse.  Thus,
including -Wno-universal-initializer in the SP_EXTRA_FLAGS variable is
redundant.

Remove the unnecessary warning flag from SP_EXTRA_FLAGS, essentially
reverting commit 1c96642326.

616e94ca24 Documentation: fix default value for core.maxTreeDepth
When `core.maxTreeDepth` was originally introduced via be20128bfa (add
core.maxTreeDepth config, 2023-08-31), its default value was 4096.

There have since been a couple of updates to its default value that were
not reflected in the documentation for `core.maxTreeDepth`:

  - 4d5693ba05 (lower core.maxTreeDepth default to 2048, 2023-08-31)
  - b64d78ad02 (max_tree_depth: lower it for MSVC to avoid stack
    overflows, 2023-11-01)

Commit 4d5693ba05 lowers the default to 2048 for platforms with smaller
stack sizes, and commit b64d78ad02 lowers the default even further when
Git is compiled with MSVC.

Neither of these changes were reflected in the documentation, which I
noticed while merging newer releases back into GitHub's private fork
(which contained the original implementation of `core.maxTreeDepth`).

Update the documentation to reflect what the platform-specific default
values are.

df8b05672c Documentation/gitpacking: make sample configs listing blocks
This document contains a few sample config snippets. At least with
Asciidoctor, the section headers are rendered *more* indented than the
variables that follow:

       [bitmapPseudoMerge "all"]
    pattern = "refs/"
    ...

To address this, wrap these listings in AsciiDoc listing blocks. Remove
the indentation from the section headings. This is similar to how we
handle such sample config elsewhere, e.g., in config.txt.

While we're here, fix the nearby "wiht" typo.

2a959ec21a t4153: stop redirecting input from /dev/zero
Commit 852a171018 (am: let command-line options override saved options,
2015-08-04) redirected a few "git am" invocations from /dev/zero, even
though it did not expect "am" to read the input. This was necessary at
the time because those tests used test_terminal, and as described in
18d8c26930 (test_terminal: redirect child process' stdin to a pty,
2015-08-04):

  Note that due to the way the code is structured, the child's stdin
  pseudo-tty will be closed when we finish reading from our stdin. This
  means that in the common case, where our stdin is attached to /dev/null,
  the child's stdin pseudo-tty will be closed immediately. Some operations
  like isatty(), which git-am uses, require the file descriptor to be
  open, and hence if the success of the command depends on such functions,
  test_terminal's stdin should be redirected to a source with large amount
  of data to ensure that the child's stdin is not closed, e.g.

              test_terminal git am --3way </dev/zero

But we later dropped the use of test_terminal in 53ce2e3f0a (am: add
explicit "--retry" option, 2024-06-06). That commit dropped one of the
redirections from /dev/zero but not the other.

In theory the remaining one should not cause any problems, but it turns
out that at least one platform (NonStop) does not have /dev/zero at all.
We never noticed before because it also did not pass the TTY prereq,
meaning these tests were not run at all there until 53ce2e3f0a.

So let's drop the useless /dev/zero mention. There are others in the
test suite, but they are run only for tests marked with EXPENSIVE (so
not typically by default).

5133ead528 Revert "reflog expire: don't use lookup_commit_reference_gently()"
During Git 2.35 timeframe, daf1d828 (reflog expire: don't use
lookup_commit_reference_gently(), 2021-12-22) replaced a call to
lookup_commit_reference_gently() with a call to lookup_commit().

What it failed to consider was that our refs do not necessarily
point at commits (most notably, we have annotated and signed tags),
and more importantly that lookup_commit() does not dereference a tag
to return a commit; instead it returns NULL when a tag is given.

Since the commit returned is used as a starting point for the
reachability check, this ejected the commits that are reachable only
by an annotated tag out of the set of reachable commits, breaking
the computation to correctly implement the "--expire-unreachable"
option.  We also started giving an error message that the API
function expected to be fed a commit object.

This problem hasn't been reported or noticed for a long time,
probably because the "refs/tags/" hierarchy by default is not
covered by reflogs, as nobody usually moves tags.

Revert the change to correctly find the commit pointed at by the ref
to restore the previous behaviour, but do so only in a more modern
codebase, as we had significant code churn since then and it is not
grave enough to worry about for older maintenance tracks.

8db8786fc2 doc: clarify post-receive hook behavior
The `githooks` documentation mentions that the post-receive hook
executes once after git-receive-pack(1) updates all references and that
it also receives the same information as the pre-receive hook on
standard input. This is misleading though because the hook only
executes once if at least one of the attempted reference updates is
successful. Also, while each line provided on standard input is in the
same format as the pre-receive hook, the information received only
includes the set of references that were successfully updated.

Update the documentation to clarify these points and also provide a
reference to the post-receive hook section of the `git-receive-pack`
documentation which has additional information.

141e13ee1a t-strvec: improve check_strvec() output
The macro check_strvec calls the function check_strvec_loc(), which
performs the actual checks.  They report the line number inside that
function on error, which is not very helpful.  Before the previous
patch half of them triggered an assertion that reported the caller's
line number using a custom message, which was more useful, but a bit
awkward.

Improve the output by getting rid of check_strvec_loc() and performing
all checks within check_strvec, as they then report the line number of
the call site, aiding in finding the broken test.  Determine the number
of items and check it up front to avoid having to do them both in the
loop and at the end.

Sanity check the expected items to make sure there are any and that the
last one is NULL, as the compiler no longer does that for us with the
removal of the function attribute LAST_ARG_MUST_BE_NULL.

Use only the actual strvec name passed to the macro, the internal
"expect" array name and an index "i" in the output, for clarity.  While
"expect" does not exist at the call site, it's reasonably easy to infer
that it's referring to the NULL-terminated list of expected strings,
converted to an array.

Here's the output with less items than expected in the strvec before:

 # check "vec->nr > nr" failed at t/unit-tests/t-strvec.c:19
 #    left: 1
 #   right: 1

... and with the patch:

 # check "(&vec)->nr == ARRAY_SIZE(expect) - 1" failed at t/unit-tests/t-strvec.c:53
 #    left: 1
 #   right: 2

With too many items in the strvec we got before:

 # check "vec->nr == nr" failed at t/unit-tests/t-strvec.c:34
 #    left: 1
 #   right: 0
 # check "vec->v[nr] == NULL" failed at t/unit-tests/t-strvec.c:36
 #    left: 0x6000004b8010
 #   right: 0x0

... and with the patch:

 # check "(&vec)->nr == ARRAY_SIZE(expect) - 1" failed at t/unit-tests/t-strvec.c:53
 #    left: 1
 #   right: 0

A broken alloc value was reported like this:

 # check "vec->alloc > nr" failed at t/unit-tests/t-strvec.c:20
 #    left: 0
 #   right: 0

 ... and with the patch:

 # check "(&vec)->nr <= (&vec)->alloc" failed at t/unit-tests/t-strvec.c:56
 #    left: 2
 #   right: 0

An unexpected string value was reported like this:

 # check "!strcmp(vec->v[nr], str)" failed at t/unit-tests/t-strvec.c:24
 #    left: "foo"
 #   right: "bar"
 #      nr: 0

... and with the patch:

 # check "!strcmp((&vec)->v[i], expect[i])" failed at t/unit-tests/t-strvec.c:53
 #    left: "foo"
 #   right: "bar"
 #       i: 0

If the strvec is not NULL terminated, we got:

 # check "vec->v[nr] == NULL" failed at t/unit-tests/t-strvec.c:36
 #    left: 0x102c3abc8
 #   right: 0x0

... and with the patch we get the line number of the caller:

 # check "!strcmp((&vec)->v[i], expect[i])" failed at t/unit-tests/t-strvec.c:53
 #    left: "bar"
 #   right: NULL
 #       i: 1

check_strvec calls without a trailing NULL were detected at compile time
before:

 t/unit-tests/t-strvec.c:71:2: error: missing sentinel in function call [-Werror,-Wsentinel]

... and with the patch it's only found at runtime:

 # check "expect[ARRAY_SIZE(expect) - 1] == NULL" failed at t/unit-tests/t-strvec.c:53
 #    left: 0x100e5a663
 #   right: 0x0

We can let check_strvec add the terminating NULL for us and remove it
from callers, making it impossible to forget.  Leave that conversion for
a future patch, though, since this reimplementation is already intrusive
enough.

9c93ba4d0a merge-recursive: honor diff.algorithm
The documentation claims that "recursive defaults to the diff.algorithm
config setting", but this is currently not the case. This fixes it,
ensuring that diff.algorithm is used when -Xdiff-algorithm is not
supplied. This affects the following porcelain commands: "merge",
"rebase", "cherry-pick", "pull", "stash", "log", "am" and "checkout".
It also affects the "merge-tree" ancillary interrogator.

This change refactors the initialization of merge options to introduce
two functions, "init_merge_ui_options" and "init_merge_basic_options"
instead of just one "init_merge_options". This design follows the
approach used in diff.c, providing initialization methods for
porcelain and plumbing commands respectively. Thanks to that, the
"replay" and "merge-recursive" plumbing commands remain unaffected by
diff.algorithm.

9ed143ee33 var(win32): do report the GIT_SHELL_PATH that is actually used
On Windows, Unix-like paths like `/bin/sh` make very little sense. In
the best case, they simply don't work, in the worst case they are
misinterpreted as absolute paths that are relative to the drive
associated with the current directory.

To that end, Git does not actually use the path `/bin/sh` that is
recorded e.g. when `run_command()` is called with a Unix shell
command-line. Instead, as of 776297548e (Do not use SHELL_PATH from
build system in prepare_shell_cmd on Windows, 2012-04-17), it
re-interprets `/bin/sh` as "look up `sh` on the `PATH` and use the
result instead".

This is the logic users expect to be followed when running `git var
GIT_SHELL_PATH`.

However, when 1e65721227 (var: add support for listing the shell,
2023-06-27) introduced support for `git var GIT_SHELL_PATH`, Windows was
not special-cased as above, which is why it outputs `/bin/sh` even
though that disagrees with what Git actually uses.

Let's fix this by using the exact same logic as `prepare_shell_cmd()`,
adjusting the Windows-specific `git var GIT_SHELL_PATH` test case to
verify that it actually finds a working executable.

92fe7c7d42 run-command(win32): resolve the path to the Unix shell early
In 776297548e (Do not use SHELL_PATH from build system in
prepare_shell_cmd on Windows, 2012-04-17), the hard-coded path to the
Unix shell was replaced by passing `sh` instead when executing Unix
shell scripts in Git.

This was done because the hard-coded path to the Unix shell is incorrect
on Windows because it not only is a Unix-style absolute path instead of
a Windows one, but Git uses the runtime prefix feature on Windows, i.e.
the correct path cannot be hard-coded.

Naturally, the `sh` argument will be resolved to the full path of said
executable eventually.

To help fixing the bug where `git var GIT_SHELL_PATH` currently does not
reflect that logic, but shows that incorrect hard-coded Unix-style
absolute path, let's resolve the full path to the `sh` executable early
in the `git_shell_path()` function so that we can use it in `git var`,
too, and be sure that the output is equivalent to what `run_command()`
does when it is asked to execute a command-line using a Unix shell.

f1ed769a3b mingw(is_msys2_sh): handle forward slashes in the sh.exe path, too
Whether the full path to the MSYS2 Bash is specified using backslashes
or forward slashes, in either case the command-line arguments need to be
quoted in the MSYS2-specific manner instead of using regular Win32
command-line quoting rules.

In preparation for `prepare_shell_cmd()` to use the full path to
`sh.exe` (with forward slashes for consistency), let's teach the
`is_msys2_sh()` function about this; Otherwise 5580.4 'clone with
backslashed path' would fail once `prepare_shell_cmd()` uses the full
path instead of merely `sh`.

This patch relies on the just-introduced fix where `fspathcmp()` handles
backslashes and forward slashes as equivalent on Windows.

193eda7507 win32: override fspathcmp() with a directory separator-aware version
On Windows, the backslash is the directory separator, even if the
forward slash can be used, too, at least since Windows NT.

This means that the paths `a/b` and `a\b` are equivalent, and
`fspathcmp()` needs to be made aware of that fact.

Note that we have to override both `fspathcmp()` and `fspathncmp()`, and
the former cannot be a mere pre-processor constant that transforms calls
to `fspathcmp(a, b)` into `fspathncmp(a, b, (size_t)-1)` because the
function `report_collided_checkout()` in `unpack-trees.c` wants to
assign `list.cmp = fspathcmp`.

Also note that `fspatheq()` does _not_ need to be overridden because it
calls `fspathcmp()` internally.

ce68178a0a strvec: declare the strvec_push_nodup() function globally
This function differs from `strvec_push()` in that it takes ownership of
the allocated string that is passed as second argument.

This is useful when appending elements to the string array that have
been freshly allocated and serve no further other purpose after that.

Without declaring this function globally, call sites would allocate the
memory, only to have `strvec_push()` duplicate the string, and then the
first copy would need to be released. Having this function globally
avoids that kind of unnecessary work.
