Subject: [PATCH v2 5/7] merge-recursive: add merge function arg to 'merge_recursive_generic'
Date: Wed, 27 Apr 2022 18:16:16 +0000 [thread overview]
Message-ID: <4537d473b937b182cd79b2f3c5673b75d92cab23.1651083378.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1171.v2.git.1651083378.gitgitgadget@gmail.com>
From: Victoria Dye <vdye@github.com>
Replace the hardcoded 'merge_recursive()' function used by the
'merge_recursive_generic()' with a caller-specific merge function. This will
allow us to use 'merge_ort_recursive()' (and therefore avoid the index
expansion of 'merge_recursive()') in commands that perform merges with
'merge_recursive_generic()', such as 'git stash pop'.
Note that this patch is strictly a refactor; all callers still use
'merge_recursive()', and any changing to 'merge_ort_recursive()' will be
done in a later commit.
