[PATCH 00/24] Header cleanups (splitting up cache.h)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Maintainer notes: (1) This series is based on a merge of
en/header-split-cleanup and ab/remove-implicit-use-of-the-repository (both
in next). (2) Although I've tweaked the series to minimize conflicts (and
this series merges syntactically cleanly with next and seen), there is a
semantic conflict with ja/worktree-orphan in seen; to correct, simply add an
include of advice.h in builtin/worktree.c.

This series builds on en/header-cleanup
(https://lore.kernel.org/git/pull.1485.v2.git.1677197376.gitgitgadget@xxxxxxxxx/)
and en/header-split-cleanup
(https://lore.kernel.org/git/pull.1493.v2.git.1679379968.gitgitgadget@xxxxxxxxx/),
and continues to focus on splitting declarations from cache.h to separate
headers.

The series may appear to be long at first glance, but is repetitive and
simple. It should be relatively easy to review, and falls into roughly 3
categories. An overview:

 * Patches 1-6: Being more explicit about dependencies. This was motivated
   by the fact that trying to find unnecessary dependencies on cache.h were
   being made harder by implicit dependencies on trace.h, trace2.h, and
   advice.h that were included via cache.h. (Similar to gettext.h handling
   in the previous series.) So I simply try to make dependencies more
   explicit, for both these headers and a few others. To make review easy, I
   split it into half a dozen patches, one header per patch (well, except
   that I handle trace.h and trace2.h together).
 * Patch 7: Remove several includes of cache.h that are no longer needed due
   to patches 1-6.
 * Patches 8-18: For several choices of FOO, move declarations of functions
   for FOO.c from cache.h to FOO.h. To simplify reviewing, each case is
   split into two patches, with the second patch cleaning up unnecessary
   includes of cache.h in other source files. (Patch 14 is a slight
   exception that wasn't split into two patches since the movement was
   otherwise so small)
 * Patches 19-24: Other small manual cleanups noticed while doing above work

Since patches 1-14 & 16-18 are just more of the same types of patches
already reviewed in the last two series, it probably makes more sense for
reviewers to focus on the other patches: 15 + 19-24 (which also happen to be
smaller). I would particularly most like review of patches 15, 21, & 24
since they are the least like any previously reviewed patches.

There are more changes I plan to make after this series graduates (still
focused around splitting up cache.h), but this series was long enough.

And thanks once again to Dscho for gitgitgadget. Getting multiple platform
testing + all the special tests (sparse, cocci, hdr-check, etc.) really
helps clean out all the issues that would otherwise hit a series like this.
