Scrum of Scrums[edit]

https://phabricator.wikimedia.org/project/board/64/
Blocked on us: https://phabricator.wikimedia.org/maniphest/query/h7YTCBTJsepS/#R

https://phabricator.wikimedia.org/T111259 closed

    • Went under the radar. Turns out the root cause got fixed by @Maxsem in MediaWiki core a few days/weeks before ;-)


Blocked on ops (sorta):
Refactor phabricator module in puppet to remove git tag pinning behavior https://phabricator.wikimedia.org/T125851
(resolved) scap::target should use scap's debian package instead of trebuchet https://phabricator.wikimedia.org/T127215


Other Team Business[edit]

Q3 goal/project check-in[edit]

Reduce CI Wait time[edit]

KPI: https://grafana.wikimedia.org/dashboard/db/releng-kpis?panelId=2&fullscreen
  • mediawiki-core-npm migrated to mediawiki-core-npm-node4.3 (ie Nodepool)
  • mediawiki services jobs being migrated. Mathoid pending on devs, Graphoid on some puppet work
  • Nodepool needs a few cherry picks, hopefully this week
  • Nodepool upgrade blocked on python-shade

Consolidate deploy tools[edit]

Migrate MediaWiki to scap3 - task T114313
Q2 Quarterly Goal hold over: Migrate all Service team owned services and MW deploys to scap3 - https://phabricator.wikimedia.org/T109926

HTTP server tests for scap

  • probably have a winner now
  • smart git http server in python, forked and modified
  • good performance over the other ones we tested
  • https://github.com/thcipriani/gpack/pull/1 - lets get this repo into phabricator.
    • Should we just merge it directly into scap? it's MIT licensed and very self-contained.
      • Tyler: I'd vote merge into scap unless there are folks with specific objections

Updated package with bugfixes for AQS (permissions issues mostly)

  • AQS is Yes Done
  • Marko was on vacation last week, will check in on what's next with him today

Working on a packaging pipeline with Antoine

  • using Jenkins etc (http://jenkins-debian-glue.org/ shell wrappers around cowbuilder / git build-package ) + aptly for publishing
  • working on setting up Beta to automatically deploy packages from a repo

Goal: make it reusable. Will be an intensive for ops to migrate the .deb repositories to Differential.

Differential Migration[edit]

https://etherpad.wikimedia.org/p/diffuerential-weekly
Integrate Differential with our Continuous Integration infrastructure - task T31
Shepherd the RFC - task T119908
Discuss at WikiDev16 - task T114320
Garner early adopter projects (goal: 1 project per WMF "team")


Other Work[edit]

Browser tests cleanup of red tests[edit]

Going well, the red line is going down without decreasing the green line much, see https://integration.wikimedia.org/ci/view/BrowserTests/view/-Dashboard/ The creation of jobs is now configured in the repos themselves via a yaml file (!!!), mostly there


beta cluster[edit]

Clean up job queue (200k stall jobs) https://phabricator.wikimedia.org/T128357 Maybe need a second jobrunner instance or run more jobs on the existing one
