It seams to me that there is no deadlock detection in mediawiki software I sometimes get mysql-errors because of deadlocks, so I hope the deadlock detection could be made better so that normal users does not see error pages and do not know what to do hopefully this helps http://dev.mysql.com/doc/refman/5.0/en/innodb-deadlocks.html
DaSch, do you still see this in more modern versions of MediaWiki?
MediaWiki can't really detect mysql DB engine level deadlocks, that's the responsibility of the DB. What MediaWiki can do is avoid holding locks for excessive time and use up-front locking in some cases to reduce the chance of deadlocks. They will not be eliminated completely.
