While trying to fix a move based on an uninitialized value (along with a
declaration after the first statement), be0fd57228
(maintenance --unregister: fix uninit'd data use &
-Wdeclaration-after-statement, 2022-11-15) unintentionally introduced a
use-after-free.
The problem arises when `maintenance_unregister()` sees a non-NULL
`config_file` string and thus tries to call
git_configset_get_value_multi() to lookup the corresponding values.
We store the result off, and then call git_configset_clear(), which
frees the pointer that we just stored. We then try to read that
now-freed pointer a few lines below, and there we have our
use-after-free:

As of it is, we're parsing subcommand with OPT_CMDMODE, which will
continue to parse more options even if the command has been found.
When we're running "git bisect run" with a command that expecting
a "--log" or "--no-log" arguments, or one of those "--bisect-..."
arguments, bisect--helper may mistakenly think those options are
bisect--helper's option.
We may fix those problems by passing "--" when calling from
git-bisect.sh, and skip that "--" in bisect--helper. However, it may
interfere with user's "--".

'git-bisect.sh' used to have a 'bisect_next_check' to check if we have
both good/bad, old/new terms set or not. In commit 129a6cf344
(bisect--helper: `bisect_next_check` shell function in C, 2019-01-02),
a subcommand for bisect--helper was introduced to port the check to C.
Since d1bbbe45df (bisect--helper: reimplement `bisect_run` shell
function in C, 2021-09-13), all users of 'bisect_next_check' was
re-implemented in C, this subcommand was no longer used but we forgot
to remove '--bisect-next-check'.
'git-bisect.sh' also used to have a 'bisect_write' function, whose
third positional parameter was a "nolog" flag. This flag was only used
when 'bisect_start' invoked 'bisect_write' to write the starting good
and bad revisions. Then 0f30233a11 (bisect--helper: `bisect_write`
shell function in C, 2019-01-02) ported it to C as a command mode of
'bisect--helper', which (incorrectly) added the '--no-log' option,
and convert the only place ('bisect_start') that call 'bisect_write'
with 'nolog' to 'git bisect--helper --bisect-write' with 'nolog'
instead of '--no-log', since 'bisect--helper' has command modes not
subcommands, all other command modes see and handle that option as well.
This bogus state didn't last long, however, because in the same patch
series 06f5608c14 (bisect--helper: `bisect_start` shell function
partially in C, 2019-01-02) the C reimplementation of bisect_start()
started calling the bisect_write() C function, this time with the
right 'nolog' function parameter. From then on there was no need for
the '--no-log' option in 'bisect--helper'. Eventually all bisect
subcommands were ported to C as 'bisect--helper' command modes, each
calling the bisect_write() C function instead, but when the
'--bisect-write' command mode was removed in 68efed8c8a
(bisect--helper: retire `--bisect-write` subcommand, 2021-02-03) it
forgot to remove that '--no-log' option.
'--no-log' option had never been used and it's unused now.
Let's remove --bisect-next-check and --no-log from option parsing.

When running 'read-tree' with a single tree and no prefix,
'prime_cache_tree()' is called after the tree is unpacked. In that
situation, skip a redundant call to 'cache_tree_update()' in
'unpack_trees()' by enabling the 'skip_cache_tree_update' unpack option.
Removing the redundant cache tree update provides a substantial performance
improvement to 'git read-tree <tree-ish>', as shown by a test added to
'p0006-read-tree-checkout.sh':

to read two trees, rather than one. The test was first introduced in
d3da223f22 (cache-tree: prefetch in partial clone read-tree, 2021-07-23) to
exercise the 'cache_tree_update()' code path, as used in 'git merge'. Since
this patch drops the call to 'cache_tree_update()' in single-tree 'git

'cache_tree_update()' is called as intended.

When deleting a branch, "git branch -d" has a safety check that ensures
the branch is merged to its upstream (if any), or to HEAD. To do that,
naturally we try to resolve HEAD to a commit object. If we're on an
orphan branch (i.e., HEAD points to a branch that does not yet exist),
that will fail, and we'll bail with an error:
$ git branch -d to-delete
fatal: Couldn't look up commit object for HEAD
This usually isn't that big of a deal. The deletion would fail anyway,
since the branch isn't merged to HEAD, and you'd need to use "-D" (or
"-f"). And doing so skips the HEAD resolution, courtesy of 67affd5173
(git-branch -D: make it work even when on a yet-to-be-born branch,
2006-11-24).
But there are still two problems:
1. The error message isn't very helpful. We should give the usual "not
fully merged" message, which points the user at "branch -D". That
was a problem even back in 67affd5173.
2. Even without a HEAD, these days it's still possible for the
deletion to succeed. After 67affd5173, commit 99c419c915 (branch
-d: base the "already-merged" safety on the branch it merges with,
2009-12-29) made it OK to delete a branch if it is merged to its
upstream.
We can fix both by removing the die() in delete_branches() completely,
leaving head_rev NULL in this case. It's tempting to stop there, as it
appears at first glance that the rest of the code does the right thing
with a NULL. But sadly, it's not quite true.
We end up feeding the NULL to repo_is_descendant_of(). In the
traditional code path there, we call repo_in_merge_bases_many(). It
feeds the NULL to repo_parse_commit(), which is smart enough to return
an error, and we immediately return "no, it's not a descendant".
But there's an alternate code path: if we have a commit graph with
generation numbers, we end up in can_all_from_reach(), which does
eventually try to set a flag on the NULL commit and segfaults.
So instead, we'll teach the local branch_merged() helper to treat a NULL
as "not merged". This would be a little more elegant in in_merge_bases()
itself, but that function is called in a lot of places, and it's not
clear that quietly returning "not merged" is the right thing everywhere
(I'd expect in many cases, feeding a NULL is a sign of a bug).
There are four tests here:
a. The first one confirms that deletion succeeds with an orphaned HEAD
when the branch is merged to its upstream. This is case (2) above.
b. Same, but with commit graphs enabled. Even if it is merged to
upstream, we still check head_rev so that we can say "deleting
because it's merged to upstream, even though it's not merged to
HEAD". Without the second hunk in branch_merged(), this test would
segfault in can_all_from_reach().
c. The third one confirms that we correctly say "not merged to HEAD"
when we can't resolve HEAD, and reject the deletion.
d. Same, but with commit graphs enabled. Without the first hunk in
branch_merged(), this one would segfault.

run_command_v_opt() and friends populate these members. This is
simpler, shorter and slightly more efficient.

Use run_command() with a struct child_process variable and populate its
"args" member directly instead of building a string array and passing it
to run_command_v_opt(). This avoids the use of magic index numbers and
makes simplifies the possible addition of more arguments in the future.

Deduplicate the code for reporting and starting the bisect run command
by moving it to a short helper function. Use a string array instead of
a strvec to prepare the arguments, for simplicity.

Build the string array av during initialization, without any magic
numbers or heap allocations. Not duplicating the result of oid_to_hex()
is safe because run_command_v_opt() duplicates all arguments already.
(It would even be safe if it didn't, but that's a different story.)

Simplify the code that builds the arguments for the "read-tree"
invocation in reset_hard() and read_empty() to remove the "verbose"
parameter.
Before 172b6428d0 (do not overwrite untracked during merge from
unborn branch, 2010-11-14) there was a "reset_hard()" function that
would be called in two places, one of those passed a "verbose=1", the
other a "verbose=0".
After 172b6428d0 when read_empty() was split off from reset_hard()
both of these functions only had one caller. The "verbose" in
read_empty() would always be false, and the one in reset_hard() would
always be true.
There was never a good reason for the code to act this way, it
happened because the read_empty() function was a copy/pasted and
adjusted version of reset_hard().
Since we're no longer conditionally adding the "-v" parameter
here (and we'd only add it for "reset_hard()" we'll be able to move to
a simpler and safer run-command API in the subsequent commit.

We are interested in exploring whether gc.cruftPacks=true should become
the default value.
To determine whether it is safe to do so, let's encourage more users to
try it out.
Users who have set feature.experimental=true have already volunteered to
try new and possibly-breaking config changes, so let's try this new
default with that set of users.

Since c2d17ba3db (branch --edit-description: protect against mistyped
branch name, 2012-02-05) we return -1 on error editing the branch
description.
Let's change to 1, which follows the established convention and it is
better for portability reasons.
