This week[edit]

Release Engineering[edit]

  • 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.
    • #mw-1.30-release MediaWiki 1.30 is about to be released in the next few days, so last call for any blockers people might have...you know...forgotten

Last week[edit]

  • 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: https://www.mediawiki.org/wiki/Talk:Development_policy/Code_Stewardship
    • [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.
