drop index if exists IndexBuildsOnFinishedBusy;
Remove obsolete Builds columns and provide accurate "Running builds" This removes the "busy", "locker" and "logfile" columns, which are no longer used by the queue runner. The "Running builds" page now only shows builds that have an active build step. 2015-10-27 14:37:17 +00:00			`alter table Builds drop column busy, drop column locker, drop column logfile;`

Ignore non-existence of IndexBuildsOnFinishedBusy Apparently for some reason not all Hydra installations had this index. Another -1 for non-declarative schema definition languages. 2015-10-28 13:08:47 +00:00			`drop index if exists IndexBuildsOnFinishedBusy;`
