We create .pack and then .idx, we consider only packfiles that have
.idx usable (those with only .pack are not ready yet), so we should
remove .idx before removing .pack for consistency.

The value of config.worktree is per-repository, but has been kept
in a singleton global variable per process. This has been OK as
most Git operations interacted with a single repository at a time,
but not right for operations like recursive "grep" that want to

The global variable has been eliminated and made into a member in
the per-repository data structure.

When installing a packfile, we place the .pack file before the .idx
file. The intention is that Git scans for .idx files in the pack
directory and then loads the .pack files from that list.
However, when we delete packfiles, we do not do this in the reverse
order as we should. The unlink_pack_path() method deletes the .pack
followed by the .idx.
This creates a window where the process could be interrupted between
the .pack deletion and the .idx deletion, leaving the repository in a
state that looks strange, but isn't actually too problematic if we
assume the pack was safe to delete. The .idx without a .pack will cause
some overhead, but will not interrupt other Git processes.
This ordering was introduced into the 'git repack' builtin by
a1bbc6c0176 (repack: rewrite the shell script in C, 2013-09-15), though
we must be careful to track history through the code move in 8434e85d5f9
(repack: refactor pack deletion for future use, 2019-06-10) to see that.
This became more important after 73320e49add (builtin/repack.c: only
collect fully-formed packs, 2023-06-07) changed how 'git repack' scanned
for packfiles for use in the cruft pack process. It previously looked
for .pack files, but that was problematic due to the order that packs
are installed: repacks between the creation of a .pack and the creation
of its .idx would result in hard failures.
There is an independent proposal about what to do in the case of a .idx
without a .pack during this 'git repack' scenario, but this change is
focused on deleting .pack files more safely.
Modify the order to delete the .idx before the .pack. The rest of the
modifiers on the .pack should still come after the .pack so we know all
of the presumed properties of the packfile as long as it exists in the
filesystem, in case we wish to reinstate it by re-indexing the .pack
file.

When redacting auth tokens in trace output from curl, we look for http/2
headers of the form "h2h3 [header: value]". This comes from b637a41ebe
(http: redact curl h2h3 headers in info, 2022-11-11).
But the "h2h3" prefix changed to just "h2" in curl's fc2f1e547 (http2:
support HTTP/2 to forward proxies, non-tunneling, 2023-04-14). That's in
released version curl 8.1.0; linking against that version means we'll
fail to correctly redact the trace. Our t5559.17 notices and fails.
We can fix this by matching either prefix, which should handle both old
and new versions.

A branch can have its configuration spread over several configuration
sections. This situation was already foreseen in 52d59cc645 (branch:
add a --copy (-c) option to go with --move (-m), 2017-06-18) when
"branch -c" was introduced.
Unfortunately, a leak was also introduced:
$ git branch foo
$ cat >> .git/config <<EOF
[branch "foo"]
some-key-a = a value
[branch "foo"]
some-key-b = b value
[branch "foo"]
some-key-c = c value
EOF
$ git branch -c foo bar

In 98e7ab6d42 (for-each-ref: delay parsing of --sort=<atom> options,
2021-10-20) a new string_list was introduced to accumulate any
"branch.sort" setting.
That string_list is cleared in ref_sorting_options(), which is only
called when processing the "--list" sub-command. Therefore, with other
sub-command, while having any sort option set, a leak is produced, e.g.:
$ git config branch.sort invalid_sort_option
$ git branch --edit-description

... in configset_iter config.c
... in repo_config config.c
... in git_config config.c
... in cmd_branch builtin/branch.c
... in run_builtin git.c
We don't have a common clean-up section in cmd_branch(). To avoid
refactoring, keep the fix simple, and while we find a better solution
which hopefuly will avoid entirely that string_list, when no sort
options are needed; let's squelch the leak sanitizer using UNLEAK().

To handle "--abbrev-ref" we use shorten_unambiguous_ref(). This
function takes a refname and returns a shortened refname, which is a
newly allocated string that needs to be freed.
Unfortunately, the refname variable is reused to receive the shortened
one. Therefore, we lose the original refname, which needs to be freed
as well, producing a leak.
This leak can be reviewed with:
$ for a in {1..10}; do git branch foo_${a}; done
$ git rev-parse --abbrev-ref refs/heads/foo_{1..10}
Direct leak of 171 byte(s) in 10 object(s) allocated from:

... in expand_ref refs.c
... in repo_dwim_ref refs.c

... in cmd_rev_parse builtin/rev-parse.c
... in run_builtin git.c
We have this leak since a45d34691e (rev-parse: --abbrev-ref option to
shorten ref name, 2009-04-13) when "--abbrev-ref" was introduced.

When git-commit sees any "--trailer" options, it passes the
COMMIT_EDITMSG file through git-interpret-trailers. But it does so
without passing --no-divider, which means that interpret-trailers will
look for a "---" divider to signal the end of the commit message.
That behavior doesn't make any sense in this context; we know we have a
complete and solitary commit message, not something we have to further
parse. And as a result, we'll do the wrong thing if the commit message
contains a "---" marker (which otherwise is not syntactically
significant), inserting any new trailers at the wrong spot.
We can fix this by passing --no-divider. This is the exact situation for
which it was added in 1688c9a489 (interpret-trailers: allow suppressing
"---" divider, 2018-08-22). As noted in the message for that commit, it
just adds the mechanism, and further patches were needed to trigger it
from various callers. We did that back then in a few spots, like
ffce7f590f (sequencer: ignore "---" divider when parsing trailers,
2018-08-22), but obviously missed this one.

discover_git_directory() started modifying the_repository in ebaf3bcf1ae
(repository: move global r_f_p_c to repo struct, 2021-06-17), when, in
the repository setup process, we started copying members from the
"struct repository_format" we're inspecting to the appropriate "struct
repository". However, discover_git_directory() isn't actually used in
the setup process (its only caller in the Git binary is
read_early_config()), so it shouldn't be doing this setup at all!
As explained by 16ac8b8db6 (setup: introduce the
discover_git_directory() function, 2017-03-13) and the comment on its
declaration, discover_git_directory() is intended to be an entrypoint
into setup.c machinery that allows the Git directory to be discovered
without side effects, e.g. so that read_early_config() can read
".git/config" before the_repository has been set up.
Fortunately, we didn't start to rely on this unintended behavior between
then and now, so we let's just remove it. It isn't harming anyone, but
it's confusing.
