Subject: [PATCH v4 18/44] cache-tree: introduce write_index_as_tree()
Date: Sun, 28 Jun 2015 22:05:40 +0800 [thread overview]
Message-ID: <1435500366-31700-19-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1435500366-31700-1-git-send-email-pyokagan@gmail.com>
A caller may wish to write a temporary index as a tree. However,
write_cache_as_tree() assumes that the index was read from, and will
write to, the default index file path. Introduce write_index_as_tree()
which removes this limitation by allowing the caller to specify its own
index_state and index file path.
