Team discussions

edit
  • Performance team stuff

MediaWiki-Core-Profiler provides the essential instrumentation needed for the above profiling.

https://www.mediawiki.org/wiki/Manual:Profiling

- Develop and maintain MediaWiki-Core-Profiler component. - Owner for its code review and issue tracker. - Owner for local development recipe. https://www.mediawiki.org/wiki/MediaWiki-Docker/Configuration_recipes/Profiling

WikimediaDebug is a browser plugin for Firefox/Chrome, which serves as the primary user interface for developers, managers, and volunteers to debug, stage, or verify deployments in production. Its code is simple and standalone, requiring no internal knowledge of our production services. https://wikitech.wikimedia.org/wiki/WikimediaDebug

This is the interface for developers to interact with: XHGui and Excimer, for profiling (listed above), Logstash, for access your own diagnostic messages (SRE/O11y), Scap, for staging code and config changes (RelEng), Varnish, for server routing (SRE/Traffic).

Responsibilities:

- Maintain and develop the WikimediaDebug browser extension (JavaScript+CSS, no dependencies). - Owner for code review and issue tracker. - Owner for releases, to appstore and Wikitech-l announcements. - Owner for user manual (wikitech doc page).

Collab sync

  • test.wikimedia.org -> k8s + closewikis + group0 wikis
    • Termination signals—traffic gets routed even though they're terminated
    • k8s deployment to canaries failed and it kept rolling—soft errors for now
  • releases host switchover - Eoghan is looking for a collaborator to plan switchover. Jaime?
    • Ensure: latest - issue of this being a general antipattern has come up
      • GitLab packages?
      • Signed tags?
      • Set commit/tag in puppet
      • Select hieradata out of strict ops/puppet control
