Subject: [PATCH 02/10] extsearchidx: avoid needless alternates rewrite in ALL.git
Date: Sat, 7 Nov 2020 10:56:52 +0000 [thread overview]
Message-ID: <20201107105700.12586-3-e@80x24.org> (raw)
In-Reply-To: <20201107105700.12586-1-e@80x24.org>
As with fill_alternates in V2Writable, we do not need to update
$GIT_DIR/objects/info/alternates if nothing is changed.
