Wikimedia Platform Engineering/MediaWiki Core Team/Check-ins/20140106

who: Brad, Nik, Bryan, Sumana, Ori, Chris, Greg, Aaron, Chad, Antoine

edit
  • Made cirrus primary for itwiki, wikidata, frwikisource, and all wikivoyages
  • Made cirrus secondary on dewiki and all wikibooks. Building now.
  • Made cirrus BetaFeature on more large wikis (frwiki, eswiki, ruwiki, and ptwiki)
  • Grabbing more small wikis Wednesday
  • enwiki as secondary next Monday unless Chad or Nik decide that is a bad idea this week.

DevOps

edit
  • Bryan has a Puppet module for Kibana (LogStash UI), now! Vetted by Antoine and Mark.
  • Ori is a jerk and has not merged Bryan’s Puppet commits for LogStash yet, but will do so today (or at Bryan’s earliest convenience).
  • Graphite is actually, really, totally migrated to tungsten in EQIAD. Now iterating on the setup to make improvements. Pairing with Faidon on this and tracking here: <https://etherpad.wikimedia.org/p/GraphiteTODO>
  • Scap: one more thing Aaron to get to before writing announce email.

Performance

edit
  • Added RunningStat (Ifedda276d) and MessagePack serialization (Id2833c5a9) to core.
  • Used by new Profiler implementation (I688e7231d). Gains: very efficient binary serialization. Data can be summarized in stages without fidelity. Measures variance and extrema (min / max) in addition to arithmetic mean and call count.
  • Domas agreed to Apache license for Mwprof, yay.
  • HHVM role in MediaWiki-Vagrant getting patches!
  • Submitted Tim’s xhprof calibration fix to HHVM: https://github.com/facebook/hhvm/pull/1488

(ori: please paste gerrit url so the lazy one can just click :D )
