Subject: [PATCH 3/6] sha1_file.c: make pack-name helper globally accessible
Date: Wed, 15 Mar 2017 17:28:18 -0400 [thread overview]
Message-ID: <20170315212818.yitqbv3dfvfb6t3u@sigill.intra.peff.net> (raw)
In-Reply-To: <20170315212617.6x57bvltinuozv4q@sigill.intra.peff.net>
We provide sha1_pack_name() and sha1_pack_index_name(), but
the more generic form (which takes its own strbuf and an
arbitrary extension) is only used to implement the other
two. Let's make it available, but clean up a few things:
1. Name it odb_pack_name(), as the original
sha1_get_pack_name() is long but not all that
descriptive.
2. Switch the strbuf argument to the beginning, so that it
matches similar path-building functions like
git_path_buf().
3. Clean up the out-dated docstring and move it to the
public declaration.
