Scrum of ScrumsEdit

This weekEdit

Release EngineeringEdit

  • Blocking
  • Blocked
  • Updates
    • [MW Train] Reminder! This is your last few weeks of deployments for the year/quarter! No non-emergency deploys starts the week of December 18th. [wiki][email]
    • [MW Train] The post mortem for T181006 (Watchlist and RecentChanges failure due to ORES on frwiki and ruwiki) is scheduled for December 7th.
    • [Sunsetting WG] Meeting with Victoria and Toby tomorrow (Wednesday).
    • [nodejs browser tests] CirrusSearch and Mobile are active with migrations.
    • [nodejs browser tests] Investigation of using mwbot instead of nodemw (javascript api interfaces to MW). CirrusSearch uses mwbot. We use nodemw (maintained by a Wikia engineer).
    • [ruby] We will upgrade rubocop (Ruby linter/static analyzer) across the corpus of extensions due to a security issue (pointed out by the new Github security issue notification service). We (WMF production and CI) are not affected by the issue AND we have officially deprecated our ruby browser test stack (where 99% of all rubocup uses/dependencies are) BUT we’ll do it :) [wiki][email]
    • [techdebt] Wider conversations regarding SLAs/stewardship of components/software:
    • [techdebt] 2nd of the 3 tech debt series of blog posts (after the 0th introduction one on Code Health) is in drafting.
    • [CI] We’ve migrated almost all of the tox (python) jobs to the new container based CI infra.

Last weekEdit

  • Blocking
  • Blocked
  • Updates
  • [Team vacations] Mukunda is out all week. Dan is only working on Monday. And of course Thurs/Fri for all US staff.
  • [MediaWiki Train] Catching up after last week’s delay due to the wikidata database crash. No MW train this week after we’ve caught up on Monday. [wiki] [email]
  • [Offsite] More team offsite logistics. Will be doing some cross team gathering with Reading (who we’re sharing a hotel/couple days overlap with).
  • A lot of Gerrit repository and Github mirror administration this past week.
  • [Phabricator] Caused and fixed a degradation of Phabricator’s search functionality last Wednesday night/Thursday morning (15th and 16th). We apologize if you were affected by this. [wiki] [email]
