Subject: [PATCH v5 2/2] diff-files: integrate with sparse index
Date: Fri, 10 Mar 2023 00:00:21 -0500 [thread overview]
Message-ID: <20230310050021.123769-3-cheskaqiqi@gmail.com> (raw)
In-Reply-To: <20230310050021.123769-1-cheskaqiqi@gmail.com>
Remove full index requirement for `git diff-files`
and test to ensure the index is not expanded in `git diff-files`.
The `p2000` tests demonstrate a ~96% execution time reduction for 'git
diff-files' and a ~97% execution time reduction for 'git diff-files'
for a file using a sparse index:
Test before after
