2018 week 26 1.32-wmf.10 Changes wmf/1.32.0-wmf.10

This MediaWiki Train Deployment is scheduled for the week of Monday, June 25th:

Monday June 25thTuesday, June 26thWednesday, June 27thThursday, June 28thFriday
Backports only.Branch wmf.10 and deploy to Group 0 Wikis.Deploy wmf.10 to Group 1 Wikis.Deploy wmf.10 to all Wikis.No deployments on fridays

How this works

  • Any serious bugs affecting wmf.10 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.

Now cdb-rebuild failed on mwdebug2002 due to lack of disk space.

Since the sync succeeded other than cdb update on mwdeploy2002, I'm going to move ahead with group0 today.

Manually cleaned up old deployments (wmf.3, wmf.4, wmf.5) to ensure enough disk space. I'm re-syncing now.

I think commons data loss occurring from Wednesday could be related to train? T198177

Current plan for today's train rollout is mentioned in {T198350#4322794}. It'll be a graduated rollout of (group1 - commonswiki), then commonswiki, then time for thorough verification that the issue is resolved, then group2 time permitting.
