Subject: [PATCH v3 21/24] pack-bitmap: factor out 'add_commit_to_bitmap()'
Date: Mon, 7 Dec 2020 19:05:44 -0500
Message-ID: <f0500190f02643aa5b88d58efe72f826bf616ade.1607385833.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1607385833.git.me@ttaylorr.com>
'find_objects()' currently needs to interact with the bitmaps khash
pretty closely. To make 'find_objects()' read a little more
straightforwardly, remove some of the khash-level details into a new
function that describes what it does: 'add_commit_to_bitmap()'.
