These are similar to the cases annotated in 5fe9e1ce2f (ref-filter: mark
unused callback parameters, 2023-02-24), but were added after that
commit.
Note that the ahead/behind callback ignores its "atom" parameter, which
is a little unusual, since that struct usually stores the result. But in
this case, the data is stored centrally in ref_array->counts, since we
want to compute all ahead/behinds at once, not per ref.

In sequencer_get_last_command(), we don't ever look at the repository
parameter. This is due to ed5b1ca10b (status: do not report errors in
sequencer/todo, 2019-06-27), which dropped the call to parse_insn_line().
However, it _should_ be used when calling into git_path_* functions,
but the one we use here is declared with the non-REPO variant of
GIT_PATH_FUNC(), and so just uses the_repository internally.
We could change the path helper to use REPO_GIT_PATH_FUNC(), but doing
so piecemeal is not great. There are 41 uses of GIT_PATH_FUNC() in
sequencer.c, and inconsistently switching one makes the code more
confusing. Likewise, this one function is used in half a dozen other
spots, all of which would need to start passing in a repository argument
(with rippling effects up the call stack).
So let's punt on that for now and just silence any -Wunused-parameter
warning.
Note that we could also drop this parameter entirely, as the function is
always called directly, and not as a callback that has to conform to
some external interface. But since we'd eventually want to use the
repository parameter, let's leave it in place to avoid disrupting the
callers twice.

Instead of just using the_repository, we can take a repository parameter
from the caller. Most of them already have one, and doing so clears up a
few -Wunused-parameter warnings. There are still a few callers which use
the_repository, but this pushes us one small step forward to eventually
getting rid of those.
Note that a few of these functions have a "rev_info" whose "repo"
parameter could probably be used instead of the_repository. I'm leaving
that for further cleanups, as it's not immediately obvious that
revs->repo is always valid, and there's quite a bit of other possible
refactoring here (even getting rid of some "struct repository" arguments
in favor of revs->repo).

Every once in a while, the `git-p4` tests flake for reasons outside of
our control. It typically fails with "Connection refused" e.g. here:
https://github.com/git/git/actions/runs/5969707156/job/16196057724
[...]
+ git p4 clone --dest=/home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git //depot
Initialized empty Git repository in /home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git/.git/
Perforce client error:
Connect to server failed; check $P4PORT.
TCP connect to localhost:9807 failed.
connect: 127.0.0.1:9807: Connection refused
failure accessing depot: could not run p4
Importing from //depot into /home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git
[...]
This happens in other jobs, too, but in the `linux-asan-ubsan` job it
hurts the most because that job often takes over a full hour to run,
therefore re-running a failed `linux-asan-ubsan` job is _very_ costly.
The purpose of the `linux-asan-ubsan` job is to exercise the C code of
Git, anyway, and any part of Git's source code that the `git-p4` tests
run and that would benefit from the attention of ASAN/UBSAN are run
better in other tests anyway, as debugging C code run via Python scripts
can get a bit hairy.
In fact, it is not even just `git-p4` that is the problem (even if it
flakes often enough to be problematic in the CI builds), but really the
part about Python scripts. So let's just skip any Python parts of the
tests from being run in that job.
For good measure, also skip the Subversion tests because debugging C
code run via Perl scripts is as much fun as debugging C code run via
Python scripts. And it will reduce the time this very expensive job
takes, which is a big benefit.

This section was added in 3d89a8c118 (Documentation/technical: add
cruft-packs.txt, 2022-05-20) to highlight a potential pitfall when
deploying cruft packs in an environment where multiple versions of Git
are GC-ing the same repository.
Now that it has been more than a year since 3d89a8c118 was written,
let's drop this section as it is no longer relevant.

This text, originally from 3d89a8c118 (Documentation/technical: add
cruft-packs.txt, 2022-05-20) lists multiple cruft packs as a potential
alternative to the design of cruft packs.
We have always supported multiple cruft packs (i.e. we use the most
recent mtime for a given object among all cruft packs which contain it,
etc.), but haven't encouraged its use.
We still aren't encouraging users to go out and generate multiple cruft
packs, but let's take a step in that direction by dropping language that
suggests we aren't capable of working with multiple cruft packs.

When pack-objects learned the `--cruft` option back in b757353676
(builtin/pack-objects.c: --cruft without expiration, 2022-05-20), we
explicitly forbade `--cruft` with `--max-pack-size`.
At the time, there was no specific rationale given in the patch for not
supporting the `--max-pack-size` option with `--cruft`. (As best I can
remember, it's because we were trying to push users towards only ever
having a single cruft pack, but I cannot be sure).
However, `--max-pack-size` is flexible enough that it already works with
`--cruft` and can shard unreachable objects across multiple cruft packs,
creating separate ".mtimes" files as appropriate. In fact, the
`--max-pack-size` option worked with `--cruft` as far back as
b757353676!
This is because we overwrite the `written_list`, and pass down the
appropriate length, i.e. the number of objects written in each pack
shard.

When reading input with the `--cruft` option, `git pack-objects` reads
each line into a strbuf, and then moves it to either the list of
discarded or fresh packs, depending on whether or not the input line
starts with a '-' character.
At the beginning of each loop iteration, the next line of input is read
with `strbuf_getline()`, which calls `strbuf_reset()` (as a part of
`strbuf_getwholeline()`) before reading the next line of input.
Thus, the call to `strbuf_reset()` (added back in b757353676
(builtin/pack-objects.c: --cruft without expiration, 2022-05-20)) at the
end of the loop is unnecessary, so let's remove it accordingly.

When t5583-push-branches.sh was originally introduced via 425b4d7f47

In fact, the test did not even run correctly until 022fbb655d (t5583:

failure at t5583.8:

SUMMARY: LeakSanitizer: 384 byte(s) leaked in 1 allocation(s).
This leak was addressed independently via 68b51172e3 (commit-reach: fix
memory leak in get_reachable_subset(), 2023-06-03), which makes t5583
leak-free.
But t5583 was not in the tree when 68b51172e3 was written, and the two
only met after the latter was merged back in via 693bde461c (Merge
branch 'mh/commit-reach-get-reachable-plug-leak', 2023-06-20).
At that point, t5583 was leak-free. Let's mark it as such accordingly.

In the topic merged via 5a4f8381b6 (Merge branch
'ab/mark-leak-free-tests', 2021-10-25), a handful of tests in the suite
were marked as leak-free.
Since then, a handful of tests have become leak-free due to changes like
- 861c56f6f9 (branch: fix a leak in setup_tracking, 2023-06-11), and
- 866b43e644 (do_read_index(): always mark index as initialized unless
erroring out, 2023-06-29)
, but weren't updated at the time to mark themselves as such. This leads
to test "failures" when running:
$ make SANITIZE=leak
$ make -C t \
GIT_TEST_PASSING_SANITIZE_LEAK=check \
GIT_TEST_SANITIZE_LEAK_LOG=true \
GIT_TEST_OPTS=-vi test
This patch closes those gaps by exporting TEST_PASSES_SANITIZE_LEAK=true
before sourcing t/test-lib.sh on most remaining leak-free tests.
There are a couple of other tests which are similarly leak-free, but not
included in the list of tests touched by this patch. The remaining tests
will be addressed in the subsequent two patches.

When I run the tests in leak-checking mode the same way our CI job does,
like:
make SANITIZE=leak \
GIT_TEST_PASSING_SANITIZE_LEAK=true \
GIT_TEST_SANITIZE_LEAK_LOG=true \
test
then LSan can racily produce useless entries in the log files that look
like this:
==git==3034393==Unable to get registers from thread 3034307.
I think they're mostly harmless based on the source here:
https://github.com/llvm/llvm-project/blob/7e0a52e8e9ef6394bb62e0b56e17fa23e7262411/compiler-rt/lib/lsan/lsan_common.cpp#L414
which reads:
PtraceRegistersStatus have_registers =
suspended_threads.GetRegistersAndSP(i, ®isters, &sp);
if (have_registers != REGISTERS_AVAILABLE) {
Report("Unable to get registers from thread %llu.\n", os_id);
// If unable to get SP, consider the entire stack to be reachable unless
// GetRegistersAndSP failed with ESRCH.
if (have_registers == REGISTERS_UNAVAILABLE_FATAL)
continue;
sp = stack_begin;
}
The program itself still runs fine and LSan doesn't cause us to abort.
But test-lib.sh looks for any non-empty LSan logs and marks the test as
a failure anyway, under the assumption that we simply missed the failing
exit code somehow.
I don't think I've ever seen this happen in the CI job, but running
locally using clang-14 on an 8-core machine, I can't seem to make it
through a full run of the test suite without having at least one
failure. And it's a different one every time (though they do seem to
often be related to packing tests, which makes sense, since that is one
of our biggest users of threaded code).
We can hack around this by only counting LSan log files that contain a
line that doesn't match our known-uninteresting pattern.

There are many reasons why discovering a Git directory may fail. In
particular, 8959555cee7 (setup_git_directory(): add an owner check for
the top-level directory, 2022-03-02) added ownership checks as a
security precaution.
Callers attempting to set up a Git directory may want to inform the user
about the reason for the failure. For that, expose the enum
discovery_result from within setup.c and move it into cache.h where
discover_git_directory() is defined.
I initially wanted to change the return type of discover_git_directory()
to be this enum, but several callers rely upon the "zero means success".
The two problems with this are:
1. The zero value of the enum is actually GIT_DIR_NONE, so nonpositive
results are errors.
2. There are multiple successful states; positive results are
successful.
It is worth noting that GIT_DIR_NONE is not returned, so we remove this
option from the enum. We must be careful to keep the successful reasons
as positive values, so they are given explicit positive values.
Instead of updating all callers immediately, add a new method,
discover_git_directory_reason(), and convert discover_git_directory() to
be a thin shim on top of it.
One thing that is important to note is that discover_git_directory()
previously returned -1 on error, so let's continue that into the future.
There is only one caller (in scalar.c) that depends on that signedness
instead of a non-zero check, so clean that up, too.
Because there are extra checks that discover_git_directory_reason() does
after setup_git_directory_gently_1(), there are other modes that can be
returned for failure states. Add these modes to the enum, but be sure to
explicitly add them as BUG() states in the switch of
setup_git_directory_gently().

done because all four options are hidden and self-explanatory.
They cause a NULL pointer dereference when using the option --help-all
with their respective tool, though. Handle such options gracefully
instead by turning the NULL pointer into an empty string at the top of

At times, we may need to push the same commit to multiple branches
in the same push. Rewinding 'next' to rebuild on top of 'master'
soon after a release is such an occasion. Making sure 'main' stays
in sync with 'master' to help those who expect that primary branch
of the project is named either of these is another.
We already use the branch name as a "concurrency group" key, but
that does not address the situation illustrated above.
Let's introduce another `concurrency` attribute, using the commit
hash as the concurrency group key, on the workflow run level, to
address this. This will hold any workflow run in the queued state
when there is already a workflow run targeting the same commit,
until that latter run completed. The `skip-if-redundant` check of
the second run will then have a chance to see whether the first
run succeeded.
The only caveat with this strategy is that only one workflow run
will be kept in the queued state by the `concurrency` feature: if
another run targeting the same commit is triggered, the
previously-queued run will be canceled. Considering the benefit,
this seems the smaller price to pay than to overload Git's build
agent pool with undesired workflow runs.

The canonical way to represent "no error hint" is making it NULL, which
shortcuts the error() call altogether. This fixes the output by removing
the line which said just "error:", which would appear when the worktree
is dirtied while editing the initial rebase todo file. This was
introduced by 97e1873 (rebase -i: rewrite complete_action() in C,
2018-08-28), which did a somewhat inaccurate conversion from shell.
To avoid that such bugs re-appear, test for the condition in

git-gui enables the "Repository->Create Desktop Icon" item on Cygwin,
offering to create a shortcut that starts git-gui on the current
repository. The code in do_cygwin_shortcut invokes function
win32_create_lnk to create the shortcut. This latter function is shared
between Cygwin and Git For Windows and expects Windows rather than unix
pathnames, though do_cygwin_shortcut provides unix pathnames. Also, this
function tries to invoke the Windows Script Host to run a javascript
snippet, but this fails under Cygwin's Tcl. So, win32_create_lnk just
does not support Cygwin.
However, Cygwin's default installation provides /bin/mkshortcut for
creating desktop shortcuts. This is compatible with exec under Cygwin's
Tcl, understands Cygwin's unix pathnames, and avoids the need for shell
escapes to encode troublesome paths. So, teach git-gui to use mkshortcut
on Cygwin, leaving win32_create_lnk unchanged and for exclusive use by
Git For Windows.
Notes: "CHERE_INVOKING=1" is recognized by Cygwin's /etc/profile and
prevents a "chdir $HOME", leaving the shell in the working directory
specified by the shortcut. That directory is written directly by
mkshortcut eliminating any problems with shell escapes and quoting.
The code being replaced includes the full pathname of the git-gui
creating the shortcut, but that git-gui might not be compatible with the
git found after /etc/profile sets the path, and might have a pathname
that defies encoding using shell escapes that can survive the multiple
incompatible interpreters involved in the chain of creating and using
this shortcut. The new code uses bare "git gui" as the command to
execute, thus using the system git to launch the system git-gui, and
avoiding both issues.

git-gui enables the "Repository->Explore Working Copy" menu on Cygwin,
offering to open a Windows graphical file browser at the root of the
working directory. This code, shared with Git For Windows support,
depends upon use of Windows pathnames. However, git gui on Cygwin uses
unix pathnames, so this shared code will not work on Cygwin.
A base install of Cygwin provides the /bin/cygstart utility that runs
a registered Windows application based upon the file type, after
translating unix pathnames to Windows. Adding the --explore option
guarantees that the Windows file explorer is opened, regardless of the
supplied pathname's file type and avoiding possibility of some other
action being taken.
So, teach git-gui to use cygstart --explore on Cygwin, restoring the
pre-2012 behavior of opening a Windows file explorer for browsing. This
separates the Git For Windows and Cygwin code paths. Note that
is_Windows is never true on Cygwin, and is_Cygwin is never true on Git
for Windows, though this is not obvious by examining the code for those
independent functions.

In the current git release, git-gui runs on Cygwin without enabling any
of git-gui's Cygwin specific code. This happens as the Cygwin specific
code in git-gui was (mostly) written in 2007-2008 to work with Cygwin's
then supplied Tcl/Tk which was an incompletely ported variant of the
8.4.1 Windows Tcl/Tk code. In March, 2012, that 8.4.1 package was
replaced with a full port based upon the upstream unix/X11 code,
since maintained up to date. The two Tcl/Tk packages are completely
incompatible, and have different signatures.
When Cygwin's Tcl/Tk signature changed in 2012, git-gui no longer
detected Cygwin, so did not enable Cygwin specific code, and the POSIX
environment provided by Cygwin since 2012 supported git-gui as a generic
unix. Thus, no-one apparently noticed the existence of incompatible
Cygwin specific code.
However, since commit c5766eae6f in the git-gui source tree
(https://github.com/prati0100/git-gui, master at a5005ded), and not yet
pulled into the git repository, the is_Cygwin function does detect
Cygwin using the unix/X11 Tcl/Tk. The Cygwin specific code is enabled,
causing use of Windows rather than unix pathnames, and enabling
incorrect warnings about environment variables that were relevant only
to the old Tcl/Tk. The end result is that (upstream) git-gui is now
incompatible with Cygwin.
So, delete Cygwin specific code (code protected by "if is_Cygwin") that
is not needed in any form to work with the unix/X11 Tcl/Tk.
Cygwin specific code required to enable file browsing and shortcut
creation is not addressed in this patch, does not currently work, and
invocation of those items may leave git-gui in a confused state.

git-gui's Makefile hardcodes the absolute Windows path of git-gui's libraries
into git-gui, destroying the ability to package git-gui on one machine and
distribute to others. The intent is to do this only if a non-Cygwin Tcl/Tk is
installed, but the test for this is wrong with the unix/X11 Tcl/Tk shipped
since 2012. Also, Cygwin does not support a non-Cygwin Tcl/Tk.
The Cygwin git maintainer disables this code, so this code is definitely
not in use in the Cygwin distribution.
The simplest fix is to just delete the Cygwin specific code,
allowing the Makefile to work out of the box on Cygwin. Do so.

The transfer.unpackLimit configuration variable is documented to be
used only as a fallback value when the more operation-specific
fetch.unpackLimit and receive.unpackLimit variables are not set, but
the implementation had the precedence reversed. Apparently this was
broken since the transfer.unpackLimit was introduced in e28714c5
(Consolidate {receive,fetch}.unpackLimit, 2007-01-24).
Often when documentation and code have diverged for so long, we
prefer to change the documentation instead, to avoid disrupting
users. But doing so would make these weirdly unlike most other
"specific overrides general" config options. And the fact that the
bug has existed for so long without anyone noticing implies to me
that nobody really tries to mix and match them much.
