Scrum of Scrums[edit]

Delete #Blocked-on-Continuous-Integration tag in favor of using #Blocked-On-Releng https://phabricator.wikimedia.org/T95310 Unlikely anyone will ever look at https://phabricator.wikimedia.org/tag/blocked-on-continuous-integration/

Beta Cluster stability[edit]

https://phabricator.wikimedia.org/project/board/497/?order=priority
Quarterly Priority: Green nightly builds on staging: https://phabricator.wikimedia.org/T88701
Quarterly Priority: Stable uptime metrics of the Staging cluster: https://phabricator.wikimedia.org/T88705

Tyler is working on rcstream

  • For context, has been setup by _joe_ (ops) and ori (dev)

Test history[edit]

Quarterly Priority: By team test history: https://phabricator.wikimedia.org/T88706

Isolated CI instances[edit]

https://phabricator.wikimedia.org/tag/continuous-integration/board/?order=priority
Quarterly Priority: Disposable VMs - https://phabricator.wikimedia.org/T47499
  • Couple meetings with Andrew B and Chase P last week
  • First server being installed in labs (labnodepool1001 https://phabricator.wikimedia.org/T95045 )
  • Antoine to refine architecture
  • We might end up setting up a brand new CI infra (Zuul + Jenkins + NodePool) in parallel of the current one then migrate
  • Our Jenkins is unpuppetized / manually configured. OpenStack has puppet manifests, should we invest time in killing that tech debt?
  • Browser tests targetting beta been broken for a day or so. Should be fine now. - the stupid bool/string DNS issue


MediaWiki Releases[edit]

Quarterly Priority: Release MediaWiki 1.25: https://phabricator.wikimedia.org/T88709
Tests broken on master!! https://phabricator.wikimedia.org/T95282 (THIS IS A BLOCKER)
  • Master do not pass tests on MediaWiki Vagrant. People rely on Jenkins passing so they probably never run tests in Vagrant.
  • Jenkins/CI stuck to PHPUnit 3.6.x for now, since we run jobs on different branches including REL1_19
    • PHPUnit job will eventually switch to composer which would bring whatever PHPUnit version devs want
  • Error: 1146 Table 'wiki.unittest_user' doesn't exist ()
    • Happens to me a ton on my Local machine. Some teardown does not happen when tests are abruptly ended with CTR+C and the unit test tables are left behind
    • Same happen with sqlite search index tables sometime.


  • Cutting REL1_25 has impacts on CI (see integration/config.git)
  • When is the branch cut?
    • Today by 23:59:59 Pacific
