Quaterly Goals for Q4[edit]

Program 1: Outcome 5: Objective 1: Maintain existing shared Continuous Integration infrastructure[edit]

Migrate away from Nodepool - task T190097
Migrate MediaWiki PHPUnit tests to Shipyard (docker-based CI) (~40% of Nodepool usage) - task T183512
Add Composer support to Blubber - task T186547
Add Python/Tox support to Blubber - task T186545
Add Ruby/Gem/Bundler/Rake support to Blubber - task T188950


Program 3: Outcome 1: Objective 2: Identify and find stewards for high-priority/high use code segment orphans[edit]

Broad role out of Code Stewardship model.
Update Maintainers/Developers page with currently known Code Stewards.
Use Code Stewardship review process to address gaps.
Deploy dashboard of Code Stewardship Coverage
  • Setup meetings for RelatedSites stewardship kickoff.
  • Reviewed Q4 candidates


Program 3: Outcome2: Objective 2: Define and implement a process to regularly address technical debt across the Foundation[edit]

Roll out of technical debt reduction approaches.
Identify early adopter engineering teams to test approaches.
  • Identified Search Platform and Platform as first two "early adopter" teams to engage with.

Program 6: Outcome 2: Objective 2: Prove viability of testing staged service containers alongside MediaWiki extension containers[edit]

Add Composer support to Blubber - task T186547
Small, standalone, MediaWiki containers built using Blubber
Limited scope with: Debian Stretch, php7, composer dependencies, Mariadb, Apache (or last two with standalone containers)
Build MW base containers upon branch cut at master branch point from core
    • Messing with Blubber/Composer and MediaWiki core but it's unclear how viable Composer-based dependency installation will be
Build ext specific containers using MW image as base
