jenkins-bot has submitted this change and it was merged. ( https://gerrit.wikimedia.org/r/340860 ) Change subject: resourceloader: Add purgeModuleDeps.php maintenance script .. resourceloader: Add purgeModuleDeps.php maintenance script Based on cleanupRemovedModules.php. Update both to use safer batching, based on known selection instead of recursing until the table is empty (which may end up deleting new rows from live traffic).
