Subject: [PATCH v2 8/9] pack-write: split up finish_tmp_packfile() function
Date: Thu, 9 Sep 2021 19:24:56 -0400 [thread overview]
Message-ID: <90bebe4e51c3bc84d156912db84e0d2774f56354.1631228928.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1631228928.git.me@ttaylorr.com>
From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>
Split up the finish_tmp_packfile() function and use the split-up version
in pack-objects.c in preparation for moving the step of renaming the
*.idx file later as part of a function change.
Since the only other caller of finish_tmp_packfile() was in
bulk-checkin.c, and it won't be needing a change to its *.idx renaming,
provide a thin wrapper for the old function as a static function in that
file. If other callers end up needing the simpler version it could be
moved back to "pack-write.c" and "pack.h".
