Subject: [PATCH 6/6] lib/load_config: deallocate / NULL database on fatal error
Date: Sat, 23 Oct 2021 10:22:38 -0300 [thread overview]
Message-ID: <20211023132238.1864400-7-david@tethera.net> (raw)
In-Reply-To: <20211023132238.1864400-1-david@tethera.net>
This fixes a potential memory leak, and makes the behaviour of
notmuch_database_load_config (somewhat) consistent with
n_d_{open,create} with config.
