The functions `repo_get_merge_bases_many()` and friends accepts an array
of commits as well as a parameter that indicates how large that array
is. This parameter is using a signed integer, which leads to a couple of
warnings with -Wsign-compare.
Refactor the code to use `size_t` to track indices instead and adapt
callers accordingly. While most callers are trivial, there are two
callers that require a bit more scrutiny:
- builtin/merge-base.c:show_merge_base() subtracts `1` from the
`rev_nr` before calling `repo_get_merge_bases_many_dirty()`, so if
the variable was `0` it would wrap. This code is fine though because
its only caller will execute that code only when `argc >= 2`, and it
follows that `rev_nr >= 2`, as well.
- bisect.ccheck_merge_bases() similarly subtracts `1` from `rev_nr`.
Again, there is only a single caller that populates `rev_nr` with
`good_revs.nr`. And because a bisection always requires at least one
good revision it follws that `rev_nr >= 1`.
Mark the file as -Wsign-compare-clean.

Coverity has started to warn about a potential double-free in
`find_bisection()`. This warning is triggered because we may modify the
list head of the passed-in `commit_list` in case it is an UNINTERESTING
commit, but still call `free_commit_list()` on the original variable
that points to the now-freed head in case where `do_find_bisection()`
returns a `NULL` pointer.
As far as I can see, this double free cannot happen in practice, as
`do_find_bisection()` only returns a `NULL` pointer when it was passed a
`NULL` input. So in order to trigger the double free we would have to
call `find_bisection()` with a commit list that only consists of
UNINTERESTING commits, but I have not been able to construct a case
where that happens.
Drop the `else` branch entirely as it seems to be a no-op anyway.
Another option might be to instead call `free_commit_list()` on `list`,
which is the modified version of `commit_list` and thus wouldn't cause a
double free. But as mentioned, I couldn't come up with any case where a
passed-in non-NULL list becomes empty, so this shouldn't be necessary.
And if it ever does become necessary we'd notice anyway via the leak
sanitizer.
Interestingly enough we did not have a single test exercising this
branch: all tests pass just fine even when replacing it with a call to
`BUG()`. Add a test that exercises it.

"git pack-refs --auto" for the files backend was too aggressive,
which has been a bit tamed.
* ps/pack-refs-auto-heuristics:
refs/files: use heuristic to decide whether to repack with `--auto`
t0601: merge tests for auto-packing of refs
wrapper: introduce `log2u()`
We have an implementation of a function that computes the log2 for an
integer. While we could instead use log2(3P), that involves floating
point numbers and is thus needlessly complex and inefficient.
We're about to add a second caller that wants to compute log2 for a
`size_t`. Let's thus move the function into "wrapper.h" such that it
becomes generally available.
While at it, tweak the implementation a bit:
- The parameter is converted from `int` to `uintmax_t`. This
conversion is safe to do in "bisect.c" because we already check that
the argument is positive.
- The return value is an `unsigned`. It cannot ever be negative, so it
is pointless for it to be a signed integer.
- Loop until `!n` instead of requiring that `n > 1` and then subtract
1 from the result and add a special case for `!sz`. This helps
compilers to generate more efficient code.
Compilers recognize the pattern of this function and optimize
accordingly. On GCC 14.2 x86_64:
log2u(unsigned long):
test rdi, rdi
je .L3
bsr rax, rdi
ret
.L3:
mov eax, -1
ret
Clang 18.1 does not yet recognize the pattern, but starts to do so on
Clang trunk x86_64. The code isn't quite as efficient as the one
generated by GCC, but still manages to optimize away the loop:
log2u(unsigned long):
test rdi, rdi
je .LBB0_1
shr rdi
bsr rcx, rdi
mov eax, 127
cmovne rax, rcx
xor eax, -64
add eax, 65
ret
.LBB0_1:
mov eax, -1
ret
The pattern is also recognized on other platforms like ARM64 GCC 14.2.0,
where we end up using `clz`:
log2u(unsigned long):
clz x2, x0
cmp x0, 0
mov w1, 63
sub w0, w1, w2
csinv w0, w0, wzr, ne
ret
Note that we have a similar function `fastlog2()` in the reftable code.
As that codebase is separate from the Git codebase we do not adapt it to
use the new function.

Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.
It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.
Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit
For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).
Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

There's several potential ways to fix those sort of leaks, we could
add a "nodup" mode to "struct strvec", which would work for the cases
where we push constant strings to it. But that wouldn't work as soon
as we used strvec_pushf(), or otherwise needed to duplicate or create
a string for that "struct strvec".

When a run command cannot be executed or found, shells return exit code
126 or 127, respectively. Valid run commands are allowed to return
these codes as well to indicate bad revisions, though, for historical
reasons. This means typos can cause bogus bisect runs that go over the
full distance and end up reporting invalid results.
The best solution would be to reserve exit codes 126 and 127, like
71b0251cdd (Bisect run: "skip" current commit if script exit code is
125., 2007-10-26) did for 125, and abort bisect run when we get them.
That might be inconvenient for those who relied on the documentation
stating that 126 and 127 can be used for bad revisions, though.
The workaround used by this patch is to run the command on a known-good
revision and abort if we still get the same error code. This adds one
step to runs with scripts that use exit codes 126 and 127, but keeps
them supported, with one exception: It won't work with commands that
cannot recognize the (manually marked) known-good revision as such.
Run commands that use low exit codes are unaffected. Typos are reported
after executing the missing command twice and three checkouts (the first
step, the known good revision and back to the revision of the first
step).

- The comment misspelled BISECT_FAILED as BISECT_FAILURE, even
though the logic it described (i.e. any non-zero return should be
reported as a single BISECT_FAILED) was correct.
- It took the return value from run_command_v_opt(), and assumed it
was either -1 or 1 upon error, which is not the case; it can relay
errors from wait_or_whine(), which can report exit status of the
