mediawiki-extensions-AbuseF.../Views/AbuseFilterViewEdit.php
Andrew Garrett 695a2aad56 Fixes from bug 19135:
* Load abuse filter data from the master for edits, prevents unintended reversion in the case of replication lag.
* Load explicit field list, preventing another issue seen on Wikimedia and described in the comments.
