Subject: [PATCH 21/37] merge-recursive: New function to assist resolving renames in-core only
Date: Mon, 20 Sep 2010 02:28:54 -0600 [thread overview]
Message-ID: <1284971350-30590-22-git-send-email-newren@gmail.com> (raw)
In-Reply-To: <1284971350-30590-1-git-send-email-newren@gmail.com>
process_renames() and process_entry() have nearly identical code for
doing three-way file merging to resolve content changes. Since we are
already deferring some of the current rename handling in order to better
handle D/F conflicts, it seems to make sense to defer content merging as
well and remove the (nearly) duplicated code sections for handling this
merging.
To facilitate this process, add a new update_stages_and_entry() function
which will map the higher stage index entries from two files involved in a
rename into the resulting rename destination's index entries, and update
the associated stage_data structure.
