Beta Cluster stability

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

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

Isolated CI instances

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

• https://www.mediawiki.org/wiki/Continuous_integration/meetings
  • Tuesdays at 14:00 UTC / 7:00am PST
  • Basically to get Antoine in habit of triaging / reporting. Might eventually move it at a better time for SF

MediaWiki Releases

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
