Earlier patches annotating unused parameters in imap-send missed a few
cases in code that is compiled only with NO_OPENSSL. These need to
retain the extra parameters to match the interfaces used when we compile
with openssl support.
Note in the case of socket_perror() that the function declaration and
parts of its code are shared between the two cases, and only the openssl
code looks at "sock". So we can't simply mark the parameter as always
unused. Instead, we can add a noop statement that references it. This is
ugly, but should be portable.

The trace2 test helper uses function pointers to dispatch to individual

The compute_generation_info code uses function pointers to abstract the

Note that we can drop the assignment of the "data" parameter in

Note that the ahead/behind callback ignores its "atom" parameter, which

In sequencer_get_last_command(), we don't ever look at the repository
parameter. This is due to ed5b1ca10b (status: do not report errors in
sequencer/todo, 2019-06-27), which dropped the call to parse_insn_line().
However, it _should_ be used when calling into git_path_* functions,
but the one we use here is declared with the non-REPO variant of
GIT_PATH_FUNC(), and so just uses the_repository internally.
We could change the path helper to use REPO_GIT_PATH_FUNC(), but doing
so piecemeal is not great. There are 41 uses of GIT_PATH_FUNC() in
sequencer.c, and inconsistently switching one makes the code more
confusing. Likewise, this one function is used in half a dozen other
spots, all of which would need to start passing in a repository argument
(with rippling effects up the call stack).
So let's punt on that for now and just silence any -Wunused-parameter
warning.
Note that we could also drop this parameter entirely, as the function is
always called directly, and not as a callback that has to conform to
some external interface. But since we'd eventually want to use the
repository parameter, let's leave it in place to avoid disrupting the
callers twice.

Instead of just using the_repository, we can take a repository parameter
from the caller. Most of them already have one, and doing so clears up a
few -Wunused-parameter warnings. There are still a few callers which use
the_repository, but this pushes us one small step forward to eventually
getting rid of those.
Note that a few of these functions have a "rev_info" whose "repo"
parameter could probably be used instead of the_repository. I'm leaving
that for further cleanups, as it's not immediately obvious that
revs->repo is always valid, and there's quite a bit of other possible
refactoring here (even getting rid of some "struct repository" arguments
in favor of revs->repo).

fsck: use enum object_type for fsck_walk callback
We prefer for callback functions to match the signature with which
they'll be called, rather than casting them to the correct type when
assigning function pointers. Even though casting often works in the real
world, it is a violation of the standard.
We did a mass conversion in 939af16eac (hashmap_cmp_fn takes
hashmap_entry params, 2019-10-06), but have grown a few new cases since
then. Because of the cast, the compiler does not complain. However, as
of clang-18, UBSan will catch these at run-time, and the case in
range-diff.c triggers when running t3206.
After seeing that one, I scanned the results of:
git grep '_fn)[^(]' '*.c' | grep -v typedef
and found a similar case in compat/terminal.c (which presumably isn't
called in the test suite, since it doesn't trigger UBSan). There might
be other cases lurking if the cast is done using a typedef that doesn't
end in "_fn", but loosening it finds too many false positives. I also
looked for:
git grep ' = ([a-z_]*) *[a-z]' '*.c'
to find assignments that cast, but nothing looked like a function.
The resulting code is unfortunately a little longer, but the bonus of
using container_of() is that we are no longer restricted to the
hashmap_entry being at the start of the struct.

We switched the function interface for fsck callbacks in a1aad71601
(fsck.h: use "enum object_type" instead of "int", 2021-03-28). However,
we accidentally flipped the type back to "int" as part of 0b4e9013f1
(fsck: mark unused parameters in various fsck callbacks, 2023-07-03).
The mistake happened because that commit was written before a1aad71601
and rebased forward, and I screwed up while resolving the conflict.
Curiously, the compiler does not warn about this mismatch, at least not
when using gcc and clang on Linux (nor in any of our CI environments).
Based on 28abf260a5 (builtin/fsck.c: don't conflate "int" and "enum" in
callback, 2021-06-01), I'd guess that this would cause the AIX xlc
compiler to complain. I noticed because clang-18's UBSan now identifies
mis-matched function calls at runtime, and does complain of this case
when running the test suite.
I'm not entirely clear on whether this mismatch is a problem in
practice. Compilers are certainly free to make enums smaller than "int"
if they don't need the bits, but I suspect that they have to promote
back to int for function calls (though I didn't dig in the standard, and
I won't be surprised if I'm simply wrong and the real-world impact would
depend on the ABI).
Regardless, switching it back to enum is obviously the right thing to do
here; the switch to "int" was simply a mistake.
