Subject: [PATCH 15/22] lib/open: check for split configuration when creating database.
Date: Sun, 14 Mar 2021 11:02:10 -0300	[thread overview]
Message-ID: <20210314140217.183425-16-david@tethera.net> (raw)
In-Reply-To: <20210314140217.183425-1-david@tethera.net>

The main functionality will be tested when notmuch-new is converted to
support split configuration. Here only the somewhat odd case of split
mail root which is actually symlinked to the database path is tested.
