Technology-wide planning[edit]

Q3 goal/project check-in[edit]


Continuous Integration Infrastructure modernization[edit]

Gather requirements for new CI system - task T153270
  • Need to dust off specifications that we worked on early, use to evaluate deployment pipeline
  • Evaluation of Pearson Deployment Pipeline continues
    • k8s infra being build on ci-staging
    • plugin (god help us all) is installed and ready
  • Random aside: can MediaWiki Config live in a containerized world?
    • No. Maybe.
  • Update from Antoine on yesterday's (Tuesday's) CI backlog
    • tl;dr: tons of jobs flooding the system, not directly due to the migration of jobs that happened on Monday (which was a 10% increase)

Migrate MediaWiki deploys to scap3 (part 2 — This time, it's personal; A.K.A Scappy Strikes Back)[edit]

Build fanout support in scap3[edit]

Have a clear course of action to get actionables done by end of quarter (sync git data to proxies post-canary check and just prior to using proxies; also need some minor puppet tweaks for some symlinks and a new vhost)
Lots of stuff getting done in scap3-MW-MVP (https://phabricator.wikimedia.org/project/view/1823/ )
Gotta fix up the mergeMessageFileList crap (extension-list)
rewriting updateWikiversions as scap plugin
Improved lock handling


Non-Quarterly goal work[edit]

Browser tests[edit]

  • T139740 Port Selenium tests from Ruby to Node.js
    • Almost there. No major changes to the commit in the last few weeks. I really think somebody should just push the big red +2 button. We can fix the minor things later.
  • T159945 Selenium/WebdriverIO tests in JavaScript/Node.js
    • Submitted skill share session for Vienna hackathon.
  • T158074 Update Ruby tests to Selenium 3
    • Done as far as we are concerned. 3 repositories left to teams to update.
  • T152963 Increase in failures caused by Saucelabs
    • Looks like T160086 (Upgrade Cucumber from version 1 to version 3) is the simplest way to rerun tests
  • T1331 Remove lines from Gemfile that are used by RVM
    • Done. An intern did all the work, Antoine and me were reviewing.

    • migrate PHP 5.3 jobs to PHP 5.5 (due end of march)
    • Think about getting more Jenkins instances (beta, one for browser tests, maybe tools-labs)
