This MediaWiki Train Deployment is scheduled for the week of Monday, February 17th:

Backports only.Branch wmf.20 and deploy to Group 0 Wikis.Deploy wmf.20 to Group 1 Wikis.Deploy wmf.20 to all Wikis.No deployments on fridays

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.
  • If you have a risky change in this week's train add a comment to this task using the Risky patch template
  • For more info about deployment blockers, see Holding the train.

After the deployment we observed some Kafka consumer lag for the udp-logging_info topic:

It recovered and then started alarming again. From what I can see there are a lot of messages like:

Use of ResourceLoaderSkinModule::getAvailableLogos with $wgLogoHD set instead of $wgLogos was deprecated in MediaWiki 1.35. [Called from ResourceLoaderSkinModule::getAvailableLogos in \/srv\/mediawiki\/php-1.35.0-wmf.20\/includes\/resourceloader\/ResourceLoaderSkinModule.php at line 339]
