Subject: [PATCH 1/5] test: add two known broken tests for missing config files
Date: Sat, 23 Oct 2021 06:24:47 -0300	[thread overview]
Message-ID: <20211023092451.1403141-2-david@tethera.net> (raw)
In-Reply-To: <20211023092451.1403141-1-david@tethera.net>

The documentation claims that the database will be set to NULL in this
case, but it is currently not happening. Based on a reproducer [1]
from Austin Ray.
