Wikimedia Platform Engineering/MediaWiki Core Team/Check-ins/20140421

who: Nik, Bryan, Chad, Chris, Greg, Tim, Dan, Ori, Aaron, RobLa regrets: Brad

Bug escalation

• JobQueue::push returns void, return value is used in code

Quarterly Review

Review action items here: https://www.mediawiki.org/wiki/Wikimedia_MediaWiki_Core_Team/Quarterly_review,_April_2014/Notes

Search

• Disk repartitioning complete (minus mgmt problem with elastic1008)
  • Search to go beta for remaining 42 wikis week of 28th (sooner? plz?)
• Snapshot stuff progressing well
• First UI/UX work being turned from mockup into some changes

Performance / HHVM

• Profiler refactoring (Aaron)
• Set domain=tld; on GeoIP cookie -- https://gerrit.wikimedia.org/r/#/c/127131/
• Mass TIFF upload incident and changes in response
• Deprecated ResourceLoaderGetStartupModules; escalated issue to Multimedia team in <http://lists.wikimedia.org/pipermail/multimedia/2014-April/000267.html>. Team requested extra time. OK.
• Closed some HHVM bugs that don’t occur on >= 3.0, ready for job runners except for Lua (Aaron)
• 6 LuaSandbox tests pass
• Logging in on beta-hhvm works now.
• Aaron brainstorming about MultimediaViewer API requests (solution might also help for CDN only thumbnails)
• GlobalCssJs cache invalidation
• Noticed and escalated regression in page save performance in VE: https://bugzilla.wikimedia.org/show_bug.cgi?id=64171

HHVM app server stack:

• Option 1: migrate from apache 2.2 + mod_php to apache 2.4 + mod_proxy_fcgi
• Option 2: have text varnishes talk directly with HHVM
  • We use Apache as a process supervisor and URL rewriting; HHVM’s built-in server does both.
  • <domas> well, at FB it is something like browser -> spdy -> edge-slb -> spdy -> origin-slb -> http -> hhvm

paravoid: maybe having a discussion with Sara regarding ABI stability and how we would ideally like to perform hhvm upgrades without rebuilding all extensions

Deployment tooling / RelEng

• Quarterly Review on the 30th
  • https://www.mediawiki.org/wiki/Wikimedia_Release_and_QA_Team/Quarterly_review,_April_2014
• Scap is now deploying MediaWiki in beta
  • Small cleanup changes happening now (moving source dir to local disk; puppet cruft)
  • Should be done this week

SecurePoll

• Dan is still trying to sync up with Brad about the slow development on this.

ContactForm for trademark

• Brad has done three of the four points that Yana wanted changing. Dan is talking to Yana about the last point, which is harder to do for technical reasons.

Security

• 1.22.6 tarball coming soon (thurs?), fixes 63251
• Global rename user - https://gerrit.wikimedia.org/r/#/c/92468/25
