Q3 goal/project check-in

edit

Consolidate deploy tools

edit
Migrate MediaWiki to scap3 - task T114313
    • no where near ;)
    • started forming a plan Friday Feb. 12th
    • still forming the experimenting plan
    • did get a lot of prereqs done (thanks to the Phabricator needs)
    • dropped the idea of using zsync (for l10n stuff) for now
    • looking into git-annex

Antoine: for l10n we have a task to use the plain .php file directly in hhvm but that exhausts hhvm caches quiet fast (no gc on hhvm)

Q2 Quarterly Goal hold over: Migrate all Service team owned services and MW deploys to scap3 - https://phabricator.wikimedia.org/T109926
    • unblocked thanks to the Phab related things (see above)
    • Tyler has a patch: making the service nodes hiera config available to use scap
      • after that is merged the ball is in the services court mostly
    • Marko/Services will be aware of this as of this coming Monday (Feb 22)
    • Getting services on Beta Cluster migrated to scap is the next obvious win
      • Services owners should own this migration as well - us supporting them
      • Then get Jenkins, on postmerge, to scap deploy on beta cluster deployment-tin
    • Tyler or someone to email Ops list after his patch is merged with the update and "yo, get migrating"


Differential Migration

edit
https://etherpad.wikimedia.org/p/diffuerential-weekly
Integrate Differential with our Continuous Integration infrastructure - task T31
  • we have scap running CI via Jenkins
  • stuff required for MW or OOUI is not in place yet
  • barrier is moving CI logic into the individual repos (?)
  • something something harbormaster (I missed what Mukunda said)
  • <insert huge zuul/dependent changes/pipeline/harbormaster discussion/pre-post-merge gate>
Shepherd the RFC - task T119908
  • not much, prereq is the above stuff on CI
Discuss at WikiDev16 - task T114320
  • done
Garner early adopter projects (goal: 1 project per WMF "team")

Reduce CI Wait time

edit
KPI: https://grafana.wikimedia.org/dashboard/db/releng-kpis?panelId=2&fullscreen

Not done / shifted. Worked on Oct-Dec 2015 completion instead ie migrate npm jobs task T119143

  • Services to Nodepool / NodeJS 4.3
  • Misc npm jobs (such as mediawiki)
  • Generic npm job

Lot of maintenance related workload (php55, generalize jobs, reviews, support) :-/

Not going to happen anytime soon. EOUTOFTIME
