When using the --schema option post-db maintenance scripts should not be run as they talk to the database directly and do not use DatabaseUpdater. Currently if you use the Flow or WikiData extensions and pass --schema without an already initialized database it will error out since their maintenance scripts are trying to talk to an empty databse. The use case for --schema is within jenkins to log the sql that was used within the test instance.
Thanks Erik, I have posted on wikitech-l: arlier 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/

Change 142383 abandoned by Hashar: Revert "Use mw-run-update-script.sh script" Reason: Will hack the bin/mw-run-update-script.sh slave script instead. This way we don't have to update all the jobs in Jenkins. https://gerrit.wikimedia.org/r/142383
Change 142386 had a related patch set uploaded by Hashar: Skip update.php --schema for now https://gerrit.wikimedia.org/r/142386
Change 142386 merged by jenkins-bot: Skip update.php --schema for now https://gerrit.wikimedia.org/r/142386
update.php --schema is now commented out. The bug in core is still valid though.
