Incoming/Needs attention

[edit]
  • TRAIN, train, train
    • how do developers convey that they've triaged the logs?
    • Lars: Commenting on the train task
    • Brennen: Don't have to come to the meeting, but still need to check train logs
    • Dan: as a train deployer, I think the most valuable thing is knowing that the dashboard is "curated"
      • Dashboard here being mediawiki-new-errors
    • Lars: when there's a logspam or some other problem, the people involved with the code are awake and available -- mostly speaking about someone from the team being available.
    • Antoine: generic mw-error dashboard is pretty usable currently. One-off errors still show up. Adding a filter can be tricky for some messages.
    • Ahmon: best filter is a nag to fix it
    • Antoine: didn't know how to reach out to CPT -- wasn't even aware that their name changed to PET -- couldn't find those folks
    • Lars: update to developers maintainers page
    • Jeena: PHP vs JavaScript errors -- I don't think those should be seperate. There are a lot of different tabs to keep open when running train so JS errrors are extra
    • Ahmon: consolidated dashboards, hardest thing to figure out who does what. Sometimes people are quick, sometimes you can't find anyone


Book club/Lunch and Learn

Monthly reflection on accomplishments - Feb '21 edition

[edit]
https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Monthly_notable_accomplishments
Add as you have them!
  • PipelineLib fully working on releases-jenkins.wikimedia.org
  • Rust introduction talk (not strictly RelEng business)
  • logspam-watch minimum hits consolidation feature

Standup!

[edit]

Ahmon

[edit]
  • Updates:
    • Added 'minimum hits' mod to logspam-watch to collapse errors than occur less than the minimum number of times.
    • https://github.com/dancysoft/mw-k8s-dev ready for Joe (and others) to check out. It builds a multiversion mediawiki image with operations/mediawiki-config (which hacks).
    • Need to work with somebody in the MW devel team to discuss offline l10n file generation (currently not possible without terrible hacks)
  • Blocked by:
    • N/A
  • Blocking:
    • Nothing hopefully


Antoine

Brennen

[edit]
  • Blocked by:
    • Nothing. (Well, maybe slightly by Nebraska, but it's not too bad.)
  • Blocking:
    • Owe some code review, as usual.
  • Updates:

Dan

[edit]
  • Blocked by:
    • Train dread
  • Blocking:
  • Updates:
    • Limited bandwidth due to train dread and daughter being sick though the latter looks ok now.
    • Jeena and Ahmon, I came up with a syntax and possible implementation for list comprehensions in pipelinelib config that might support the multiversion build in a generalized way. Would love input if we all have time this week. Otherwise async or next Monday

Jeena

[edit]
  • Blocked by:
  • Blocking:
    • mediawiki-docker reviews
    • local-charts review
  • Updates:
    • Working on the following:
    • pipelinelib credentials
    • mw-on-k8s secrets
    • dev sat survey
    • local dev (see blocking)
    • starting mw-expedition to learn more about mw development

Lars

[edit]
  • Blocked by:
    • nope?
  • Blocking:
    • nope?
  • Updates:
    • Been trying to get Scap tests run under Python3 on Debian 9 (stretch).
      • No luck so far. pip refuses to install some of the dependencies.
      • I don't like Python anymore.
      • If we could switch production to current Debian stable that would be nice, thankyouverymuch
