[02/12] treewide: remove unnecessary includes in source files

Commit Message

Elijah Newren Dec. 3, 2023, 6:41 a.m. UTC

From: Elijah Newren <[e-mail]>

Each of these were checked with
   gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).

...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file.  These cases were:
  * builtin/credential-cache.c
  * builtin/pull.c
  * builtin/send-pack.c

An in-flight topic seem to want to see git_env_bool() that is
declared in parse.h that is pulled in via inclusion of config.h
hence this hunk breaks 'seen'.

An in-flight topic starts using "struct key_value_info" that is
available via the inclusion of "config.h", hence this hunk breaks
the build of 'seen'.

I'll register the following evil merge as the merge-fix/ for this
topic.

In addition, t/helper/test-fast-rebase.c that is touched by this
step will simply disappear with the cc/git-replay topic, so it may
not be a bad idea to exclude it from the patchset.

Thanks.

It seems that we have gained another topic in flight that gets
broken by this change.  I can keep piling merge-fixes on top, but it
does not look like a strategy that would scale well.

Can we get this series thoroughly reviewed quickly to merge it down
via 'next' to 'master' soonish, so that other topics can be rebased
on the result, or is that too much to ask during the Winter lull?

Thanks.

The Winter lull is my winter surge, so I can certainly quickly make
whatever changes are required (well, assuming I can shake this
fever...).  But that doesn't help much with reviewing, since that
should be done by someone other than the author.  However, these
particular type of changes are pretty innocuous; there's really not
anything clever going on, it's just a lot of gruntwork, and
does-it-compile is most of the review.

Anyway, I'll reroll, dropping or holding back any changes that
conflict with next or seen, and see if that encourages anyone to chime
in.
