There are two -Wsign-compare warnings in "scalar.c", both of which are
trivial:
- We mistakenly use a signed integer to loop towards an upper unsigned
bound in `cmd_reconfigure()`.
- We subtract `path_sep - enlistment->buf`, which results in a signed
integer, and use the value in a ternary expression where second
value is unsigned. But as `path_sep` is being assigned the result of
`find_last_dir_sep(enlistment->buf + offset)` we know that it must
always be bigger than or equal to `enlistment->buf`, and thus the
result will be positive.
Address both of these warnings.

In `get_one_patchid()` we assign either the result of `strlen()` or
`remove_space()` to `len`. But while the former correctly returns a
`size_t`, the latter returns an `int` to indicate the length of the
stripped string even though it cannot ever return a negative value. This
causes a warning with "-Wsign-conversion".
In fact, even `get_one_patchid()` itself is also using an integer as
return value even though it always returns the length of the patch, and
this bubbles up to other callers.
Adapt the function and its helpers to use `size_t` for string lengths
consistently.

The `length` variable is used to store how many bytes we wish to emit
from an object ID. This value will either be the full hash algorithm's
length, or the abbreviated hash that can be set via `--abbrev` or the
"core.abbrev" option. The former is of type `size_t`, whereas the latter
is of type `int`, which causes a warning with "-Wsign-compare".
The reason why `abbrev` is using a signed type is mostly that it is
initialized with `-1` to indicate that we have to compute the minimum
abbreviation length. This length is computed via `find_alignment()`,
which always gets called before `emit_other()`, and thus we can assume
that the value would never be negative in `emit_other()`.
In fact, we can even assume that the value will always be at least
`MINIMUM_ABBREV`, which is enforced by both `git_default_core_config()`
and `parse_opt_abbrev_cb()`. We implicitly rely on this by subtracting
up to 3 without checking for whether the value becomes negative. We then
pass the value to printf(3p) to print the prefix of our object's ID, so
if that assumption was violated we may end up with undefined behaviour.
Squelch the warning by asserting this invariant and casting the value of
`abbrev` to `size_t`. This allows us to store the whole length as an
unsigned integer, which we can then pass to `fwrite()`.

There are a couple of -Wsign-comparison warnings in "gpg-interface.c".
Most of them are trivial and simply using signed integers to loop
towards an upper unsigned bound.
But in `parse_signed_buffer()` we have one case where the different
signedness of the two values of a ternary expression results in a
warning. Given that:
- `size` will always be bigger than `len` due to the loop condition.
- `eol` will always be after `buf + len` because it is found via
memchr(3p) starting from `buf + len`.
We know that both values will always be natural integers.
Squelch the warning by casting the left-hand side to `size_t`.

The `max_connections` type tracks how many children git-daemon(1) would
spawn at the same time. This value can be controlled via a command line
switch: if given a positive value we'll set that up as the limit. But
when given either zero or a negative value we don't enforce any limit at
all.
But even when being passed a negative value we won't actually store it,
but normalize it to 0. Still, the variable used to store the config is
using a signed integer, which causes warnings when comparing the number
of accepted connections (`max_connections`) with the number of current
connections being handled (`live_children`).
Adapt the type of `max_connections` such that the types of both
variables match.

We have a bunch of loops which iterate up to an unsigned boundary using
a signed index, which generates warnigs because we compare a signed and
unsigned value in the loop condition. Address these sites for trivial
cases and enable `-Wsign-compare` warnings for these code units.
This patch only adapts those code units where we can drop the
`DISABLE_SIGN_COMPARE_WARNINGS` macro in the same step.

Similar to the preceding commit, we get a warning in `get_packet_data()`
on 32 bit platforms due to our lenient use of `ssize_t`. This function
is kind of curious though: we accept an `unsigned size` of bytes to
read, then store the actual number of bytes read in an `ssize_t` and
return it as an `int`. This is a whole lot of integer conversions, and
in theory these can cause us to overflow when the passed-in size is
larger than `ssize_t`, which on 32 bit platforms is implemented as an
`int`.
None of the callers of that function even care about the number of bytes
we have read, so returning that number is moot anyway. Refactor the
function such that it only returns an error code, which plugs the
potential overflow. While at it, convert the passed-in size parameter to
be of type `size_t`.

On 32-bit platforms, ssize_t may be "int" while size_t may be
"unsigned int". At times we compare the number of bytes we read
stored in a ssize_t variable with "unsigned int", but that is done
after we check that we did not get an error return (which is
negative---and that is the whole reason why we used ssize_t and not
size_t), so these comparisons are safe.
But compilers may not realize that. Cast these to size_t to work
around the false positives. On platforms with size_t/ssize_t wider
than a normal int, this won't be an issue.

The `struct diff_flags` structure is essentially an array of flags, all
of which have the same type. We can thus use `sizeof()` to iterate
through all of the flags, which we do in `diff_flags_or()`. But while
the statement returns an unsigned integer, we used a signed integer to
iterate through the flags, which generates a warning.
Fix this by using `size_t` for the index instead.

GCC generates a warning in "headless.c" because we compare `slash` with
`size`, where the former is an `int` and the latter is a `size_t`. Fix
the warning by storing `slash` as a `size_t`, as well.
This commit is being singled out because the file does not include the

Explicitly ignore "-Wsign-compare" warnings in our bundled copy of the
regcomp implementation. We don't use the macro introduced in the
preceding commit because this code does not include "git-compat-util.h"
in the first place.
Note that we already directly use "#pragma GCC diagnostic ignored" in
"regcomp.c", so it shouldn't be an issue to use it directly in the new
spot, either.

When compiling with DEVELOPER=YesPlease, we explicitly disable the
"-Wsign-compare" warning. This is mostly because our code base is full
of cases where we don't bother at all whether something should be signed
or unsigned, and enabling the warning would thus cause tons of warnings
to pop up.
Unfortunately, disabling this warning also masks real issues. There have
been multiple CVEs in the Git project that would have been flagged by
this warning (e.g. CVE-2022-39260, CVE-2022-41903 and several fixes in
the vicinity of these CVEs). Furthermore, the final audit report by
X41 D-Sec, who are the ones who have discovered some of the CVEs, hinted
that it might be a good idea to become more strict in this context.
Now simply enabling the warning globally does not fly due to the stated
reason above that we simply have too many sites where we use the wrong
integer types. Instead, introduce a new set of macros that allow us to
mark a file as being free of warnings with "-Wsign-compare". The
mechanism is similar to what we do with `USE_THE_REPOSITORY_VARIABLE`:
every file that is not marked with `DISABLE_SIGN_COMPARE_WARNINGS` will
be compiled with those warnings enabled.
These new markings will be wired up in the subsequent commits.

Commit a30154187a (describe: stop traversing when we run out of names,
2024-10-31) taught git-describe to automatically reduce the
max_candidates setting to match the total number of possible names. This
lets us break out of the traversal rather than fruitlessly searching for
more candidates when there are no more to be found.
However, setting max_candidates to 0 (e.g., if the repo has no tags)
overlaps with the --exact-match option, which explicitly uses the same
value. And this causes a regression with --always, which is ignored in
exact-match mode. We used to get this in a repo with no tags:
$ git describe --always HEAD
b2f0a7f
and now we get:
$ git describe --always HEAD
fatal: no tag exactly matches 'b2f0a7f47f5f2aebe1e7fceff19a57de20a78c06'
The reason is that we bail early in describe_commit() when
max_candidates is set to 0. This logic goes all the way back to
2c33f75754 (Teach git-describe --exact-match to avoid expensive tag
searches, 2008-02-24).
We should obviously fix this regression, but there are two paths,
depending on what you think:
$ git describe --always --exact-match
and
$ git describe --always --candidates=0
should do. Since the "--always" option was added, it has always been
ignored in --exact-match (or --candidates=0) mode. I.e., we treat
--exact-match as a true exact match of a tag, and never fall back to
using --always, even if it was requested.
If we think that's a bug (or at least a misfeature), then the right
solution is to fix it by removing the early bail-out from 2c33f75754,
letting the noop algorithm run and then hitting the --always fallback
output. And then our regression naturally goes away, because it follows
the same path.
If we think that the current "--exact-match --always" behavior is the
right thing, then we have to differentiate the case where we
automatically reduced max_candidates to 0 from the case where the user
asked for it specifically. That's possible to do with a flag, but we can
also just reimplement the logic from a30154187a to explicitly break out
of the traversal when we run out of candidates (rather than relying on
the existing max_candidates check).
My gut feeling is along the lines of option 1 (it's a bug, and people
would be happy for "--exact-match --always" to give the fallback rather
than ignoring "--always"). But the documentation can be interpreted in
the other direction, and we've certainly lived with the existing
behavior for many years. So it's possible that changing it now is the
wrong thing.
So this patch fixes the regression by taking the second option,
retaining the "--exact-match" behavior as-is. There are two new tests.
The first shows that the regression is fixed (we don't even need a new
repo without tags; a restrictive --match is enough to create the
situation that there are no candidate names).
The second test confirms that the "--exact-match --always" behavior
remains unchanged and continues to die when there is no tag pointing at
the specified commit. It's possible we may reconsider this in the
future, but this shows that the approach described above is implemented
faithfully.
We can also run the perf tests in p6100 to see that we've retained the
speedup that a30154187a was going for:

Currently if we want to have a remote/HEAD locally that is different
from the one on the remote, but we still want to get a warning if remote
changes HEAD, our only option is to have an indiscriminate warning with
"follow_remote_head" set to "warn". Add a new option
"warn-if-not-$branch", where $branch is a branch name we do not wish to
get a warning about. If the remote HEAD is $branch do not warn,
otherwise, behave as "warn".
E.g. let's assume, that our remote origin has HEAD
set to "master", but locally we have "git remote set-head origin seen".
Setting 'remote.origin.followRemoteHEAD = "warn"' will always print
a warning, even though the remote has not changed HEAD from "master".
Setting 'remote.origin.followRemoteHEAD = "warn-if-not-master" will
squelch the warning message, unless the remote changes HEAD from
"master". Note, that should the remote change HEAD to "seen" (which we
have locally), there will still be no warning.
Improve the advice message in report_set_head to also include silencing
the warning message with "warn-if-not-$branch".

In 'midx-write.c' there are a lot of static functions which use global
variables `the_repository` or `the_hash_algo`. In a follow up commit,
the repository variable will be added to `write_midx_context`, which
some of the functions can use. But for functions which do not have
access to this struct, pass down the required information from
non-static functions `write_midx_file` and `write_midx_file_only`.
This requires that the function `hash_to_hex` is also replaced with
`hash_to_hex_algop` since the former internally accesses the
`the_hash_algo` global variable.
This ensures that the usage of global variables is limited to these
non-static functions, which will be cleaned up in a follow up commit.

Commit da91a90c2f (fast-import: disallow more path components,
2024-11-30) added two separate verify_path() calls (one for
added/modified files, and one for renames/copies). But our tests only
exercise the first one. Let's protect ourselves against regressions by
tweaking one of the tests to rename into the bad path. There are
adjacent tests that will stay as additions, so now both calls are
covered.

In 454ea2e4d7 (treewide: use get_all_packs, 2018-08-20) we converted
existing calls to both:
- get_packed_git(), as well as
- the_repository->objects->packed_git
, to instead use the new get_all_packs() function.
In the instance that this commit addresses, there was a preceding call
to prepare_packed_git(), which dates all the way back to 660c889e46
(sha1_file: add for_each iterators for loose and packed objects,
2014-10-15) when its caller (for_each_packed_object()) was first
introduced.
This call could have been removed in 454ea2e4d7, since get_all_packs()
itself calls prepare_packed_git(). But the translation in 454ea2e4d7 was
(to the best of my knowledge) a find-and-replace rather than inspecting
each individual caller.
Having an extra prepare_packed_git() call here is harmless, since it
will notice that we have already set the 'packed_git_initialized' field
and the call will be a noop. So we're only talking about a few dozen CPU
cycles to set up and tear down the stack frame.
But having a lone prepare_packed_git() call immediately before a call to
get_all_packs() confused me, so let's remove it as redundant to avoid
more confusion in the future.

The `multi_pack_index` struct represents the MIDX for a repository.
Here, we add a pointer to the repository in this struct, allowing direct
use of the repository variable without relying on the global
`the_repository` struct.
With this addition, we can determine the repository associated with a
`bitmap_index` struct. A `bitmap_index` points to either a `packed_git`
or a `multi_pack_index`, both of which have direct repository
references. To support this, we introduce a static helper function,
`bitmap_repo`, in `pack-bitmap.c`, which retrieves a repository given a
`bitmap_index`.
With this, we clear up all usages of `the_repository` within
`pack-bitmap.c` and also remove the `USE_THE_REPOSITORY_VARIABLE`
definition. Bringing us another step closer to remove all global
variable usage.
Although this change also opens up the potential to clean up `midx.c`,
doing so would require additional refactoring to pass the repository
struct to functions where the MIDX struct is created: a task better
suited for future patches.

The variables `packed_git_window_size` and `packed_git_limit` are global
config variables used in the `packfile.c` file. Since it is only used in
this file, let's change it from being a global config variable to a
local variable for the subsystem.
With this, we rid `packfile.c` from all global variable usage and this
means we can also remove the `USE_THE_REPOSITORY_VARIABLE` guard from
the file.
