How this works

  • Any serious bugs affecting wmf.14 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.

FYI: This train will contain the code switching ParserCache from PHP serialization to JSON serialization: T263579
The code is disabled by default, thus it *should* be a no-op. We have also put significant efforts into testing backward and forward compatibility for this feature, see T264397 - a new serialization testing framework was made and we added few hundred tests for various combinations of versions, cached objects etc. In case the train needs to be reverted, we've already put compatibility code in there, so things should behave well after a revert. We feel fairly confident in this change, but please be aware anyways.

I'm taking over as backup train conductor.

Train's been at group2 for about 22 hours. I'm tempting fate by declaring this done.
