Subject: [PATCH 1/6] clone|fetch: preserve mtime of modified manifest.js.gz
Date: Thu, 20 Oct 2022 08:43:09 +0000	[thread overview]
Message-ID: <20221020084314.1668067-2-e@80x24.org> (raw)
In-Reply-To: <20221020084314.1668067-1-e@80x24.org>

When we cull manifest.js.gz for ignored epochs, attempt to
preserve mtime of the updated manifest.js.gz since it can
be used to optimize future fetches.
