e8d56ca863 CODE_OF_CONDUCT.md: update PLC members list
As part of our code of conduct, we maintain a list of active members on
the Project Leadership Committee, which serves a couple of purposes. The
details are in 3f9ef874a7 (CODE_OF_CONDUCT: mention individual
project-leader emails, 2019-09-26), but the gist is as follows:

  - It makes it clear that people with a CoC complaint may contact
    members individually as opposed to the general PLC list (in case the
    subject of their complaint has to do with one of the committee
    members).

  - It also serves as the de-facto list of people on the PLC, which
    isn't committed anywhere else in the tree.

As of [1], Peff is no longer a member of Git's Project Leadership
Committee. Let's update the list of active members accordingly [2].

This also gives us a convenient opportunity to thank Peff for his many
years of service on the PLC, during which he helped the Git community in
more ways than we can easily list here.

ff5b7913f0 sequencer, stash: fix running from worktree subdir
In commits bc3ae46b42 ("rebase: do not attempt to remove
startup_info->original_cwd", 2021-12-09) and 0fce211ccc ("stash: do not
attempt to remove startup_info->original_cwd", 2021-12-09), we wanted to
allow the subprocess to know which directory the parent process was
running from, so that the subprocess could protect it.  However...

When run from a non-main worktree, setup_git_directory() will note
that the discovered git directory
(/PATH/TO/.git/worktree/non-main-worktree) does not match
DEFAULT_GIT_DIR_ENVIRONMENT (see setup_discovered_git_dir()), and
decide to set GIT_DIR in the environment.  This matters because...

Whenever git is run with the GIT_DIR environment variable set, and
GIT_WORK_TREE not set, it presumes that '.' is the working tree.  So...

This combination results in the subcommand being very confused about
the working tree.  Fix it by also setting the GIT_WORK_TREE environment
variable along with setting cmd.dir.

A possibly more involved fix we could consider for later would be to
make setup.c set GIT_WORK_TREE whenever (a) it discovers both the git
directory and the working tree and (b) it decides to set GIT_DIR in the
environment.  I did not attempt that here as such would be too big of a
change for a 2.35.1 release.

519947b69a checkout: avoid BUG() when hitting a broken repository
When 9081a421 (checkout: fix "branch info" memory leaks, 2021-11-16)
cleaned up existing memory leaks, we added an unrelated sanity check
to ensure that a local branch is truly local and not a symref to
elsewhere that dies with BUG() otherwise.  This was misguided in two
ways.  First of all, such a tightening did not belong to a leak-fix
patch.  And the condition it detected was *not* a bug in our program
but a problem in user data, where warning() or die() would have been
more appropriate.

As the condition is not fatal (the result of computing the local
branch name in the code that is involved in the faulty check is only
used as a textual label for the commit), let's revert the code to
the original state, i.e. strip "refs/heads/" to compute the local
branch name if possible, and otherwise leave it NULL.  The consumer
of the information in merge_working_tree() is prepared to see NULL
in there and act accordingly.

6327f0efed branch,checkout: fix --track documentation
Document that the accepted variants of the --track option are --track,
--track=direct, and --track=inherit.  The equal sign in the latter two
cannot be replaced with whitespace; in general optional arguments need
to be attached firmly to their option.

Put "direct" consistently before "inherit", if only for the reasons
that the former is the default, explained first in the documentation,
and comes before the latter alphabetically.

Mention both modes in the short help so that readers don't have to look
them up in the full documentation.  They are literal strings and thus
untranslatable.  PARSE_OPT_LITERAL_ARGHELP is inferred due to the pipe
and parenthesis characters, so we don't have to provide that flag
explicitly.

Mention that -t has the same effect as --track and --track=direct.
There is no way to specify inherit mode using the short option, because
short options generally don't accept optional arguments.

The German translation for "'%s' is aliased to '%s'" is incorrect. It

e2724c1ed1 getcwd(mingw): handle the case when there is no cwd
A recent upstream topic introduced checks for certain Git commands that
prevent them from deleting the current working directory, introducing
also a regression test that ensures that commands such as `git version`
_can_ run without a current working directory.

While technically not possible on Windows via the regular Win32 API, we
do run the regression tests in an MSYS2 Bash which uses a POSIX
emulation layer (the MSYS2/Cygwin runtime) where a really evil hack
_does_ allow to delete a directory even if it is the current working
directory.

Therefore, Git needs to be prepared for a missing working directory,
even on Windows.

This issue was not noticed in upstream Git because there was no caller
that tried to discover a Git directory with a deleted current working
directory in the test suite. But in the microsoft/git fork, we do want
to run `pre-command`/`post-command` hooks for every command, even for
`git version`, which means that we make precisely such a call. The bug
is not in that `pre-command`/`post-command` feature, though, but in
`mingw_getcwd()` and needs to be addressed there.

As Ævar pointed out in [1], the use of PARSE_OPT_LITERAL_ARGHELP with a

git-checkout were changed in d311566 (branch: add flags and config to
inherit tracking, 2021-12-20) to use this discouraged combination for
their --track flags.

Fix this by removing PARSE_OPT_LITERAL_ARGHELP, and changing the arghelp
to simply be "mode". Users may discover allowed values in the manual
pages.

2b95d94b05 Makefile: FreeBSD cannot do C99-or-below build
In "make DEVELOPER=YesPlease" builds, we try to help developers to
catch as many potential issues as they can by using -Wall and
turning compilation warnings into errors.  In the same spirit, we
recently started adding -std=gnu99 to their CFLAGS, so that they can
notice when they accidentally used language features beyond C99.

It however turns out that FreeBSD 13.0 mistakenly uses C11 extension
in its system header files regardless of what __STDC_VERSION__ says,
which means that the platform (unless we tweak their system headers)
cannot be used for this purpose.

It seems that -std=gnu99 is only added conditionally even in today's
config.mak.dev, so it is fine if we dropped -std=gnu99 from there.
Which means that developers on FreeBSD cannot participate in vetting
use of features beyond C99, but there are developers on other
platforms who will, so it's not too bad.

We might want a more "fundamental" fix to make the platform capable
of taking -std=gnu99, like working around the use of unconditional
C11 extension in its system header files by supplying a set of
"replacement" definitions in our header files.  We chose not to
pursue such an approach for two reasons at this point:

 (1) The fix belongs to the FreeBSD project, not this project, and
     such an upstream fix may happen hopefully in a not-too-distant
     future.

 (2) Fixing such a bug in system header files and working it around
     can lead to unexpected breakages (other parts of their system
     header files may not be expecting to see and do not work well
     with our "replacement" definitions).  This close to the final
     release of this cycle, we have no time for that.

5906910794 t1450-fsck: exec-bit is not needed to make loose object writable
A test case wants to append stuff to a loose object file to ensure
that this kind of corruption is detected. To make a read-only loose
object file writable with chmod, it is not necessary to also make
it executable. Replace the bitmask 755 with the instruction +w to
request only the write bit and to also heed the umask. And get rid
of a POSIXPERM prerequisite, which is unnecessary for the test.

cac15b3fb4 refs API: use "failure_errno", not "errno"
Fix a logic error in refs_resolve_ref_unsafe() introduced in a recent
series of mine to abstract the refs API away from errno. See
96f6623ada (Merge branch 'ab/refs-errno-cleanup', 2021-11-29)for that
series.

In that series introduction of "failure_errno" to
refs_resolve_ref_unsafe came in ef18119dec (refs API: add a version
of refs_resolve_ref_unsafe() with "errno", 2021-10-16). There we'd set
"errno = 0" immediately before refs_read_raw_ref(), and then set
"failure_errno" to "errno" if errno was non-zero afterwards.

Then in the next commit 8b72fea7e9 (refs API: make
refs_read_raw_ref() not set errno, 2021-10-16) we started expecting
"refs_read_raw_ref()" to set "failure_errno". It would do that if
refs_read_raw_ref() failed, but it wouldn't be the same errno.

So we might set the "errno" here to any arbitrary bad value, and end
up e.g. returning NULL when we meant to return the refname from
refs_resolve_ref_unsafe(), or the other way around. Instrumenting this
code will reveal cases where refs_read_raw_ref() will fail, and
"errno" and "failure_errno" will be set to different values.

In practice I haven't found a case where this scary bug changed
anything in practice. The reason for that is that we'll not care about
the actual value of "errno" here per-se, but only whether:

 1. We have an errno
 2. If it's one of ENOENT, EISDIR or ENOTDIR. See the adjacent code
    added in a1c1d8170d (refs_resolve_ref_unsafe: handle d/f
    conflicts for writes, 2017-10-06)

I.e. if we clobber "failure_errno" with "errno", but it happened to be
one of those three, and we'll clobber it with another one of the three
we were OK.

Perhaps there are cases where the difference ended up mattering, but I
haven't found them. Instrumenting the test suite to fail if "errno"
and "failure_errno" are different shows a lot of failures, checking if
they're different *and* one is but not the other is outside that list
of three "errno" values yields no failures.

But let's fix the obvious bug. We should just stop paying attention to
"errno" in refs_resolve_ref_unsafe(). In addition let's change the
partial resetting of "errno" in files_read_raw_ref() to happen just
before the "return", to ensure that any such bug will be more easily
spotted in the future.
