Greg to copy to etherpad after meeting: https://etherpad.wikimedia.org/p/Scrum-of-Scrums

Incoming from last week[edit]

  • Blocking:
    • Fundraising Tech: CRM tests still regularly failing due to full mysql partition on integration hosts. Possible fix noted by Eileen on https://phabricator.wikimedia.org/T205950
      • ACTION: Tyler to comment on the task with his proposal

Outgoing this week (wrong section heading is on purpose for copy/pasting into Scrum of Scrums etherpad[edit]

Release Engineering[edit]

  • Blocked by:
  • Blocking:
  • Updates:
    • Train Health:
      • Last week: 1.33.0-wmf.1 deployment blockers https://phabricator.wikimedia.org/T206655
        • Six blockers closed, one opened on friday after conclusion of the train
        • Group1 was delayed until Thursday and Group2 finally happened late Thursday evening.
        • Otherwise it was a mostly uneventful train. The blockers were perhaps more worrisome than destructive, no outages occurred.
      • This week: 1.33.0-wmf.2 deployment blockers https://phabricator.wikimedia.org/T206656
      • Next week:
    • Log Health:

Other work[edit]

Selenium[edit]

Gerrit[edit]

  • Upgrade this week barring anything strange from the mailing lists

Phabricator[edit]

  • I've implemented a prototype extension that can map urls like https://phabricator.wikimedia.org/train/1.33.0-wmf.1/ to the corresponding train blockers task.
    • This will also support /train/current to map to the currently active train.
    • This can also support other task-series schemes such as /swat/2018-10-31.1/
