Subject: mdocml: Changing existing SQLite databases was utterly broken: 1) SQL
Date: Mon, 3 Jun 2013 18:51:15 -0400 (EDT) [thread overview]
Message-ID: <201306032251.r53MpFou010545@krisdoz.my.domain> (raw)
Log Message:
-----------
Changing existing SQLite databases was utterly broken:
1) SQL statements were only prepared when creating a new database.
2) We rely heavily on foreign_keys, but never enabled them.
