Subject: [PATCH 6/7] v2writable: don't verify tip if reindexing
Date: Fri, 25 Dec 2020 10:21:14 +0000	[thread overview]
Message-ID: <20201225102115.6745-7-e@80x24.org> (raw)
In-Reply-To: <20201225102115.6745-1-e@80x24.org>

We only rely on git-rev-parse to resolve symbolic names ("HEAD")
to a SHA-* git commit ID.  We'll assume any git commit IDs we
get from SQLite DBs are valid and let "git-log" fail if it
isn't.
