Subject: [PATCH v2 17/19] read-cache: write resolve-undo data for index-v5
Date: Fri, 12 Jul 2013 19:27:02 +0200 [thread overview]
Message-ID: <1373650024-3001-18-git-send-email-t.gummerer@gmail.com> (raw)
In-Reply-To: <1373650024-3001-1-git-send-email-t.gummerer@gmail.com>
Make git read the resolve-undo data from the index.
Since the resolve-undo data is joined with the conflicts in
the ondisk format of the index file version 5, conflicts and
resolved data is read at the same time, and the resolve-undo
data is then converted to the in-memory format.
