How this works

  • Any serious bugs affecting wmf.20 should be added as subtasks beneath this one.
  • Any open subtask(s) block the train from moving forward.This means no further deployments until the blockers are resolved.
  • If something is serious enough to warrant a rollback then you should bring it to the attention of deployers on the #wikimedia-operations IRC channel.
  • For more info about deployment blockers, see Holding the train.

There was again T203566: ParserOutput cache incompatibility errors in 1.32.0-wmf.20 which is "just" a cache issue as I understand it. It only happens when the new version is rolled and disappear after that once the cache has been repopulated.

T203567: Warning: Invalid operand type was used: implode() expects a container as one of the arguments in /srv/mediawiki/php-1.32.0-wmf.20/includes/parser/ParserOutput.php on line 428 could potentially have been a blocker, but it does not seem to have much impact. The log spam is fairly limited and it is being looked at.

There are some spikes of memcached errors, that is mc2** hosts being rebooted in codfw.

I'm not sure T203661 should block the train. Cosmetic error which is irritating but not broken, and is self-correcting the next time the page is edited. Not to say we won't back-port a fix for it, but "stop the train" is (and should be) a higher bar.

ack, thanks for the feedback, I was being overly cautious.

Can we declare this Resolved? The wmf.20 is everywhere…

T203566 is still being worked on but, yeah, we have rolled out, and T203566 explicitly prevents us from rolling back as well (we tried..), so fine to close.

I have left it open indicating that some issues where still being working on. But yeah the stack looks more or less fine now.
