Such originaldb would be empty for an instance used just for regression testing and could in fact only contain the objectcache table. If it's a developer machine he would use the originaldb for local testing, but a nigthly would not need to (in fact, errors trying to access those missing tables would be useful for detecting errors in the isolating system). _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
