Pairing (#together / #byob) / Weekly Triages

Good opportunity: "Upgrade beta-cluster caches to jessie"

• https://phabricator.wikimedia.org/T98758

 ** Tyler, Dan, Chad!

Need to create instances and prepare patches for mediawiki-config and puppet. Then a good 2 hours sprint to switch all beta cluster caches from Trusty to Jessie. #together

Scrum of Scrums

no news is good news :)

Beta Cluster

https://phabricator.wikimedia.org/project/board/497/?order=priority

• Request for admin rights on http://fa.wikipedia.beta.wmflabs.org/ - https://phabricator.wikimedia.org/T100251
  • Closed but good question
  • Delegate the hell out of this task

Deployment Cabal

• Big goal for next quarter (discuss, change, etc):
  • deploy services! Restbase
    • current RESTBase deployment workflow: https://wikitech.wikimedia.org/wiki/RESTBase
    • general service deployment workflow: https://wikitech.wikimedia.org/wiki/User:Mobrovac/Service_Deployment
  • should allow batches (specify via config or at runtime)
  • should run checks (what do those look like?)
  • should roll back
  • should get running in deployment-prep by quarter's end (no explicit dependencies on ops—ops feedback throughout [obvs])
  • keep deployment cabal group running as a means of sanity checks
  • RelEng code: Tyler, Chad, Mukunda—Dan to facilitate discussion

Isolated CI instances

https://phabricator.wikimedia.org/tag/continuous-integration/board/?order=priority

Quarterly Priority: Disposable VMs - https://phabricator.wikimedia.org/T47499

• Access request
  • https://phabricator.wikimedia.org/T102133
• wikitech/OpenStackManager upgrade
  • instance creation/deletion now doable via puppet/nova, enabling nodepool to create new instances that work

Phabricator

• Upstream phabricator has merged a giant bunch of UI changes, I'm a little scared to pull it
  • see: https://secure.phabricator.com/
  • Will probably push the last version from them before the merge, and give them a few days to patch things before we pull the major changes.
  • Regardless, eventually we've got to bite the bullet. I expect some people to hate the new UI, it's a fairly drastic difference
    • I don't think it's all that different. Only thing I expect people to gripe over is the smaller font choices.

• Repo reading via https on Phab now available!
  • I also discovered that phabricator's repo hosting over https doesn't scale well to very large repositories. Workaround: use ssh. I don't think ours are big enough to worry but there's that.
    • We need to figure out more here and see if it's fixable.

Other Work

• make-wmf-branch is now resumable - https://phabricator.wikimedia.org/T101935
  • Gonna test it today ( though hopefully it won't fail and require resuming )
