Change Details

T183242 asks for write operations to fail on connections to database replicas. But write operations should fail for all connections that obtained for the DB_REPLICA index, even if that connection is to a master database. This is useful to flush out errors early during development, considering that the typical development environment does not use database replicas.

MediaWiki should catch any attempts to write to a database replica. This addresses part of the requirement of T183242.
