All of it in table form:

Quarterly Goals[edit]

Program 1: Outcome 5: Milestone 1: Develop and migrate to a JavaScript-based browser testing stack[edit]

Due: End of this quarter
What: Specific improvements to the now canonical framework, see: task T182421, notably:
Upgrade webdriverIO to version 4.9
Investigate replacing nodemw with mwbot
Video recording for Selenium tests in Node.js
Task: task T182421
* no major updates this past week: Z's been sick over the holdiays, sadly

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

Draft requirements for a Kubernetes based solution for CI - task T183513
Migrate MediaWiki PHPUnit tests to Shipyard (docker-based CI) (~40% of Nodepool usage) - task T183512
    • most npm jobs are migrated. Gotta handle the /deploy repositories that have a node_modules commited in
    • PHPUnit not started yet
  • Unify production and CI docker image build process - task T177276
    • npm from the Debian package (1.4.x) does not support running behind a proxy task T183569. Prevents building npm based Docker container on contint1001.

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

Due: End of quarter

Nothing new to report

Quaterly non-goal "Work"[edit]

Program 1: Outcome 1: Objective 1: Scap (Tech Debt Sprint FY201718-Q2)[edit]

  • Need to get the scap CI situation figured out because of repeated breakage of scap in beta. Two competing needs:
    • Need a place to test scap changes
    • Other teams use scap in beta to test their own deployments

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

Program 1: Outcome 6: Milestone 1: Maintain Gerrit[edit]

Program 1: Outcome 6: Milestone 2: Maintain Phabricator[edit]

Streamline logspam workflows by adding some integration with phabricator
Store git-lfs (and other phab uploads) in swift: task T182085

Program 1: Outcome 5: Objective 1: MW Nightlies server[edit]

  • We're building non-security nightlies! (not quite stable enough to announce to public yet)
    • \o/
  • Working with security team to figure out best way to manage patches with minimal overhead
  • any changes to weekly branch cut process coming soon?

Other work[edit]

  • Working on a Hive query to find out how many unique users are hitting WikipediaMobileFirefoxOS in a month
select count(distinct ip) from webrequest where year = 2017 and month = 12 and uri_host = '' and uri_path = '/WikipediaMobileFirefoxOS/index.html';
^^^ Seems like it over-counts, given how frequently mobile IPs can change ^^^
  • More apache docroot cleanup
