Since 4c28e4ada03 (commit: die before asking to edit the log
message, 2010-12-20), we have been "leaking" the "author_ident" when
prepare_to_commit() fails. Instead of returning from right there,
introduce an exit status variable and jump to the clean-up label
at the end.
Instead of explicitly releasing the resource with strbuf_release(),
mark the variable with UNLEAK() at the end, together with two other
variables that are already marked as such. If this were in a
utility function that is called number of times, but these are
different, we should explicitly release resources that grow
proportionally to the size of the problem being solved, but
cmd_commit() is like main() and there is no point in spending extra
cycles to release individual pieces of resource at the end, just
before process exit will clean everything for us for free anyway.
This fixes a leak demonstrated by e.g. "t3505-cherry-pick-empty.sh",
but unfortunately we cannot mark it or other affected tests as passing
now with "TEST_PASSES_SANITIZE_LEAK=true" as we'll need to fix many
other memory leaks before doing so.
Incidentally there are two tests that always passes the leak checker
with or without this change. Mark them as such.
This is based on an earlier patch by Ævar, but takes a different
approach that is more maintainable.

Since 522354d70f4 (Add Travis CI support, 2015-11-27) the CI has used
http://filehost.perforce.com/perforce/ to download binaries from
filehost.perforce.com, they were then moved to this script in
657343a602e (travis-ci: move Travis CI code into dedicated scripts,
2017-09-10).
Let's use https instead for good measure. I don't think we need to
worry about the DNS or network between the GitHub CI and perforce.com
being MitM'd, but using https gives us extra validation of the payload
at least, and is one less thing to worry about when checking where
else we rely on non-TLS'd http connections.
Also, use the same download site at perforce.com for Linux and macOS
tarballs for consistency.

5ed9fc3fc86 (ci: prevent `perforce` from being quarantined, 2020-02-27)
introduces this prevention for brew, but brew has been removed in a
previous commit, so reintroduce an equivalent option to avoid a possible
regression.
This doesn't affect github actions (as configure now) and is therefore
done silently to avoid any possible scary irrelevant messages.

Perfoce's cask in brew is meant[1] to be used only by humans, so replace
its use from the CI with a scripted binary download which is less likely
to fail, as it is done in Linux.
Kept the logic together so it will be less likely to break when moved
around as on the fly code changes in this area are settled, at which
point it will also feasable to ammend it to avoid some of the hardcoded
values by using similar variables to the ones Linux does.
In that same line, a POSIX sh syntax is used instead of the similar one
used in Linux in preparation for an unrelated future change that might
change the shell currently configured for it.
This change reintroduces the risk that the installed binaries might not
work because of being quarantined that was fixed with 5ed9fc3fc86 (ci:
prevent `perforce` from being quarantined, 2020-02-27) but fixing that
now was also punted for simplicity and since the affected cloud provider
is scheduled to be retired with an on the fly change, but should be
addressed if that other change is not integrated further.
The discussion on the need to keep 2 radically different versions of
the binaries to be tested with Linux vs macOS or how to upgrade to
newer versions now that brew won't do that automatically for us has
been punted for now as well. On that line the now obsolete comment
about it in lib.sh was originally being updated by this change but
created conflicts as it is moved around by other on the fly changes,
so will be addressed independently as well.

In preparation for a future change that will make perforce installation
optional in macOS, make sure that the check for it is done without
triggering scary looking errors and add a user friendly message instead.
All other existing uses of 'type <cmd>' in our shell scripts that
check the availability of a command <cmd> send both standard output
and error stream to /dev/null to squelch "<cmd> not found" diagnostic
output, but this script left the standard error stream shown.
Redirect it just like everybody else to squelch this error message that
we fully expect to see.

This would happen as we stat'd the non-existing
".git/objects/info/commit-graph" file. Let's fix mark_commit_graphs()
to check the stat()'s return value, and while we're at it fix another
case added in the same commit to do the same.
The caller in expire_commit_graphs() would have been less likely to
run into this, as it's operating on files it just got from readdir(),
but it could still happen due to a race with e.g. a concurrent "rm
-rf" of the commit-graph files.

Fix a regression in my 3b6a8db3b03 (object-file.c: use "enum" return
type for unpack_loose_header(), 2021-10-01) revealed both by running
the test suite with --valgrind, and with the amended "git fsck" test.
In practice this regression in v2.34.0 caused us to claim that we
couldn't parse the header, as opposed to not being able to unpack
it. Before the change in the C code the test_cmp added here would emit:
-error: unable to unpack header of ./objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
+error: unable to parse header of ./objects/e6/9de29bb2d1d6434b8b29ae775ad8c2e48c5391
I.e. we'd proceed to call parse_loose_header() on the uninitialized
"hdr" value, and it would have been very unlikely for that
uninitialized memory to be a valid git object.
The other callers of unpack_loose_header() were already checking the
enum values exhaustively. See 3b6a8db3b03 and
5848fb11acd (object-file.c: return ULHR_TOO_LONG on "header too long",
2021-10-01).

When the "--add-file" option is used to add the contents from an
untracked file to the archive, the permission mode bits for these
files are sent to the archive-backend specific "write_entry()"
method as-is. We normalize the mode bits for tracked files way
before we pass them to the write_entry() method; we should do the
same here.
This is not strictly needed for "tar" archive-backend, as it has its
own code to further clean them up, but "zip" archive-backend is not
so well prepared.

Fix a bug in "git pull" where `submodule.recurse` is preferred over
`fetch.recurseSubmodules` when performing a fetch
(Documentation/config/fetch.txt says that `fetch.recurseSubmodules`
should be preferred.). Do this by passing the value of the
"--recurse-submodules" CLI option to the underlying fetch, instead of
passing a value that combines the CLI option and config variables.
In other words, this bug occurred because builtin/pull.c is conflating
two similar-sounding, but different concepts:
- Whether "git pull" itself should care about submodules e.g. whether it
should update the submodule worktrees after performing a merge.
- The value of "--recurse-submodules" to pass to the underlying "git
fetch".
Thus, when `submodule.recurse` is set, the underlying "git fetch" gets
invoked with "--recurse-submodules[=value]", overriding the value of
`fetch.recurseSubmodules`.
An alternative (and more obvious) approach to fix the bug would be to
teach "git pull" to understand `fetch.recurseSubmodules`, but the
proposed solution works better because:
- We don't maintain two identical config-parsing implementions in "git
pull" and "git fetch".
- It works better with other commands invoked by "git pull" e.g. "git
merge" won't accidentally respect `fetch.recurseSubmodules`.

Commit 73c6de06aff8 ("bisect: don't use invalid oid as rev when
starting") changes the behaviour of `git bisect` to consider invalid
oids as pathspecs again, as in the old shell implementation.
While that behaviour may be desirable, it can also cause confusion. For
example, while bisecting in a particular repo I encountered this:
$ git bisect start d93ff48803f0 v6.3
$
...which led to me sitting for a few moments, wondering why there's no
printout stating the first rev to check.
It turns out that the tag was actually "6.3", not "v6.3", and thus the
bisect was still silently started with only a bad rev, because
d93ff48803f0 was a valid oid and "v6.3" was silently considered to be a
pathspec.
While this behaviour may be desirable, it can be confusing, especially
with different repo conventions either using or not using "v" before
release names, or when a branch name or tag is simply misspelled on the
command line.
In order to avoid situations like this, make it more clear what we're
waiting for:
$ git bisect start d93ff48803f0 v6.3
status: waiting for good commit(s), bad commit known
We already have good output once the bisect process has begun in
earnest, so we don't need to do anything more there.
