Subject: [PATCH v3 01/15] diff --color-moved: add perf tests
Date: Wed, 27 Oct 2021 12:04:08 +0000 [thread overview]
Message-ID: <8fc8914a37b3c343cd92bb0255088f7b000ff7f7.1635336262.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.981.v3.git.1635336262.gitgitgadget@gmail.com>
From: Phillip Wood <phillip.wood@dunelm.org.uk>
Add some tests so we can monitor changes to the performance of the
move detection code. The tests record the performance of a single
large diff and a sequence of smaller diffs.
Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk>
