Subject: [PATCH 06/10] merge-ort: copy and adapt merge_3way() from merge-recursive.c
Date: Fri, 18 Dec 2020 05:51:23 +0000 [thread overview]
Message-ID: <611141f24af2c8d706fbf2dc6ef776ca61391e41.1608270687.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.815.git.1608270687.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
Take merge_3way() from merge-recursive.c and make slight adjustments
based on different data structures (direct usage of object_id
rather diff_filespec, separate pathnames which based on our careful
interning of pathnames in opt->priv->paths can be compared with '!='
rather than 'strcmp').
