Train status and happenings[edit]

Quarterly Goals for Q4[edit]


TEC1 (Maint): Outcome 1 / Output 1.1[edit]

GOAL: Undeploy the CodeReview extension.
WHO: James, need help from CPT
  • James will ping CPT about this this week (April 8th)
    • … and again w/c 15 April.
    • … and again w/c 6 May (in SoS).
    • … and again w/c 27 May (in SoS).

TEC1 (Maint): Outcome 1 / Output 1.1[edit]

GOAL: Setup 1-3 of the CI WG options (Zuul v3, Argo, GitLab)
  • Focus on a couple noteworthy repos: e.g.,
    • core
    • extensions
    • ops/puppet
  • Maybe setup in serial, i.e., a week per evaluation
  • Questions:
    • RelEng/Extended working group?
      • At least in the WG eval it was good to have non-familiar people
      • But maybe with the setup of options it might be beneficial to have experienced with current setup people.
      • Folks outside the original working group to join-in to setup options; people TBD
    • Do we need a rubric before we do this prototyping? (yes)
      • DONE lars to work on rubric week of 2019-04-01
        • See email 2019-04-08
    • CI arch doc in team google drive now, open for feedback
  • 2019-05-06: Feedback from Android. Working on an arch document. Do in Q1?

TEC3 (Pipeline): Outcome 1 / Output 1.2[edit]

GOAL: Instrument Quibble for data collection
WHO: Mukunda, Antoine

TEC3 (Pipeline): Outcome 1 / Output 1.2[edit]

GOAL: Create a graph where time is spent and make a prioritized list for improvements.
WHO: Mukunda, Antoine
  • Blocked

TEC3 (Pipeline): Outcome 1 / Output 1.2[edit]

GOAL: Prepare the Deployment Pipeline for changes to our CI tooling.
WHO: ???, ???
  • Blocked by not having new CI tooling yet

TEC3 (Pipeline): Outcome 3 / Output 3.1[edit]

GOAL: Create a .pipeline/config.yaml standard to give users more control over how their tests are run in the pipeline and allow the easy saving of artifacts at pipeline completion. (RelEng)
WHO: Dan, Tyler, ???
  • Implementation is working, but in testing a Blubber .pipeline/config.yaml there are some glaring deficiencies
  • Long term concerns about Groovy implementation include:
    • Dependencies on Jenkins and many plugins
    • Groovy CPS is a huge pain to debug and it's rarely clear that CPS is the issue when things go awry; Instead, the code just executes in unexpected ways.

TEC3 (Pipeline): Outcome 3 / Output 3.1[edit]

Adopt more services into Deployment pipeline - task T212801
Wikidata Termbox SSR, Kask for Session Storage Service, cpjobqueue (stretch), ORES (stretch)
WHO: Dan, Tyler, Lars

There are tasks: https://phabricator.wikimedia.org/T220403

  • changeprop

  • Wikidata Termbox SSR
  • Kask for Session Storage Service
  • cpjobqueue (stretch)

TEC12 (DevProd): Outcome 1 / Output 1.1[edit]

GOAL: Provide an "Official" Docker base image for local development of MediaWiki based on the production tooling.
WHO: Jeena, Brennen
  • Done for MediaWiki, for some values of "done" and "MediaWiki". Production-likeness needs considerable work.

TEC13 (Code Health): Outcome 1 / Output 3[edit]

GOALs: Presentation/session(s) at the Wikimedia Hackathon on the current state of Code Health projects (technical debt and code stewardship)

TEC13 (Code Health): Outcome 1 / Output 1.1[edit]

Publish a re-imagination of the Review Queue process.
Develop and implement metrics around task and code-review responsiveness
WHO: Greg, JR (and Andre)
  • Closed call for participation in Code Review workgroup. Working on scheduling kickoff meeting.

= TEC13 (Code Health): Outcome 4 / Output 4.2[edit]

Expand SonarQube reporting into CI infrastructure
Perform SonarQube analysis on all extensions
Engage user communities in direct feedback solicitation
WHO: JR, Zeljko, Code Health Metrics
  • We currently have 6 extensions in the new pipeline, will be at 10 within the week. Planning to push for the rest of extensions starting next week.
  • Core is not currently in a state to be added due to extended unit test run times. Project (non CHMWG) underway to seperate unit for integration tests.
  • Looking to expand to other areas of analysis such as Python/SCAP. This will require some wramp up and assistance from others.

Other non-goal work[edit]
