From: Elijah Newren Date: Mon, 20 Sep 2010 08:28:54 +0000 (-0600) Subject: merge-recursive: New function to assist resolving renames in-core only X-Git-Tag: v1.7.4-rc0~101^2~18 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=2ff739f9d2fd2f34e7a7bfb9b5f2d1d2b2ec5326;p=git.git merge-recursive: New function to assist resolving renames in-core only 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.
