Hello, Earlier today I slightly changed how Jenkins run the MediaWiki extension job. Specifically the way the database is updated. We used to simply: php maintenance/update.php I wanted to log the SQL queries behind added to the database and the script has a --schema option to do just that. So Jenkins now: php maintenance/update.php --schema update_sql.log sleep 1 php maintenance/update.php The sleep is needed because --schema still write to the update_log database. The two runs ends up having the same ul_key in the table since it just vary by timestamp (so if two run occurs in the same second, the second has a duplicate key error). There should be a better fix, but sleep 1 works ™ Flow had an issue with the tests failing because --schema still run the post-db maintenance script (might be the cause of above problem). Erik Bernhardson figured out a temporary workaround for Flow: https://gerrit.wikimedia.org/r/#/c/142303/ The issue is tracked by https://bugzilla.wikimedia.org/67163 Any help welcome! -- Antoine "hashar" Musso
