Subject: [PATCH v5 10/27] refs: add methods to init refs db
Date: Thu, 18 Feb 2016 00:17:33 -0500 [thread overview]
Message-ID: <1455772670-21142-11-git-send-email-dturner@twopensource.com> (raw)
In-Reply-To: <1455772670-21142-1-git-send-email-dturner@twopensource.com>
Alternate refs backends might not need the refs/heads directory and so
on, so we make ref db initialization part of the backend.
