Subject: [PATCH 21/49] builtin/repack.c: factor our "generated_pack_install"
Date: Sun, 28 Sep 2025 18:08:31 -0400 [thread overview]
Message-ID: <96d27261e75fd2ae46d9633b3d4eff243dbcc187.1759097191.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1759097191.git.me@ttaylorr.com>
Once all new packs are known to exist, 'repack' installs their contents
from their temporary location into their permanent one. This is a
semi-involved procedure for each pack, since for each extension (e.g.,
".idx", ".pack", ".mtimes", and so on) we have to either:
- adjust the filemode of the temporary file before renaming it into
place, or
- die() if we are missing a non-optional extension, or
- unlink() any existing file for extensions that we did not generate
(e.g., if a non-cruft pack we generated was identical to, say, a
cruft pack which existed at the beginning of the process, we have to
remove the ".mtimes" file).
Extract this procedure into its own function, and call it
"generated_pack_install"(). This will set us up for pulling this
function out of the builtin entirely and making it part of the repack.h
API, which will be done in a future commit.
