Subject: [PATCH v2 00/17] Header cleanups
Date: Fri, 24 Feb 2023 00:09:19 +0000	[thread overview]
Message-ID: <pull.1485.v2.git.1677197376.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1485.git.1677139521.gitgitgadget@gmail.com>

Maintainer note: This series cleanly merges with next, but has TWO minor
conflicts with ed/fsmonitor-inotify. The correct resolution is to take
ed/fsmonitor-inotify's copy of both compat/fsmonitor/fsm-settings-darwin.c
and compat/fsmonitor/fsm-ipc-darwin.c, but to add a #include
"git-compat-util.h" line at the top of compat/fsmonitor/fsm-settings-unix.c
and a #include "hex.h" somewhere near the top of
compat/fsmonitor/fsm-ipc-unix.c

Changes since v1:

 * Fixed a bad squash; moved the changes to the right commit
 * More thorough justification in the commit message for the 2nd commit
 * Removed an accidental added include of gettext.h (the file was used, but
   it makes it harder to review that patch)
 * Add some explanation of surprising changes to commit messages
 * Add a new commit which removes the include of hex.h from cache.h, and
   instead makes C files include it directly, as suggested by Stolee

This series cleans up headers a bit, trying to remove excessive dependency
on "cache.h". I created this series a while ago, but decided to clean it up
and submit it due to Emily's recent thread and suggestion that this might be
helpful to their efforts[1].

There are many more cleanups I could do in this area, but the series is
already a good size.

Notes:

 * Big props to Dscho for gitgitgadget; being able to test on a bunch of
   platforms with a variety of configurations easily is a big win in general
   but especially for series like this one.
 * I used the scripts at
   https://github.com/newren/git/commit/db81c8d7fb554b3edf04320e218bddeb98bb6194,
   and some tweaks thereof, repeatedly while making this series (though they
   are prone to produce both false positive and false negatives, so if you
   use them, only use them to generate hints about which files to look at).

          treewide: remove unnecessary git-compat-util.h includes in headers
      
     -    Since git-compat-util.h needs to be included first in C files, having it
     -    appear in header files is unnecessary.  More importantly, having it
     -    included in header files seems to lead to folks leaving it out of C
     -    files, which makes it harder to verify that the rule is being followed.
     -    Remove it from header files, other than the ones that have been approved
     -    as alternate first includes.
     +    For sanity, we should probably do one of the following:
     +
     +    (a) make C and header files both depend upon everything they need
     +    (b) consistently exclude git-compat-util.h from headers and require it
     +        be the first include in C files
     +
     +    Currently, we have some of the headers following (a) and others
     +    following (b), which makes things messy.  In the past I was pushed
     +    towards (b), as per [1] and [2].  Further, during this series I
     +    discovered that this mixture empirically will mean that we end up with C
     +    files that do not directly include git-compat-util.h, and do include
     +    headers that don't include git-compat-util.h, with the result that we
     +    likely have headers included before an indirect inclusion of
     +    git-compat-util.h.  Since git-compat-util.h has tricky platform-specific
     +    stuff that is meant to be included before everything else, this state of
     +    affairs is risky and may lead to things breaking in subtle ways (and
     +    only on some platforms) as per [1] and [2].
     +
     +    Since including git-compat-util.h in existing header files makes it
     +    harder for us to catch C files that are missing that include, let's
     +    switch to (b) to make the enforcement of this rule easier.  Remove the
