Subject: [PATCHv6 31/31] merge-recursive: ensure we write updates for directory-renamed file
Date: Fri, 5 Jan 2018 12:27:11 -0800 [thread overview]
Message-ID: <20180105202711.24311-32-newren@gmail.com> (raw)
In-Reply-To: <20180105202711.24311-1-newren@gmail.com>
When a file is present in HEAD before the merge and the other side of the
merge does not modify that file, we try to avoid re-writing the file and
making it stat-dirty. However, when a file is present in HEAD before the
merge and was in a directory that was renamed by the other side of the
merge, we have to move the file to a new location and re-write it.
Update the code that checks whether we can skip the update to also work in
the presence of directory renames.
