Callouts[edit]


Technology[edit]

Analytics[edit]

  • Blockers: none
  • Updates
    • Working full steam to hit our goal of having a backend for wikistats 2.0 to support editing metrics (unique devices and pageviews are alredy supported on ui). It is looking like we are going to split our current druid cluster (6 hosts) into two clusters: one private, one public so restbase services connect to public cluster. The security concerns arising from this decision will probably make the goal spill into next quarter but we will have an alpha next quarter if no suprises arise.
    • We have use differential for 1 quarter and we are going back to gerrit, not much value added.
    • Eventlogging purging progressing much too slowly, it is becoming clear we cannot sustain mysql backend for EventLogging, we are prioritizing sunsetting mysql, replacing it with a better EventLogging analytics experience on the Hadoop cluster
    • Removing outdated instrumentation of events from EventLogging that are now automagically available via eventbus, like “page create”. https://gerrit.wikimedia.org/r/#/c/379137/

Audiences[edit]

Readers[edit]

Multimedia[edit]

  • Pushing out 3D to test/test2 today (Wednesday)
  • Need read-only time on s4 for a schema change related to 3D (adding a new media type)
  • Beginning work on MediaInfo extension for Wikibase, which will continue for some time.

iOS native app[edit]

Discovery[edit]

  • Putting together plan for automating portal deployments
Maps[edit]
  • nodejs 6.11 done
  • Figuring out what to do with code no one on the team is in charge of

Web[edit]

  • Turning off OCG. Investigating using chromium for printing.

Reading Infrastructure[edit]

  • MCS: Dealing with sectioning issues before Parsoid adds <section> tags
  • Reading Lists: finishing RESTBase part; MediaWiki part going through security review

Contributors[edit]

Global Collaboration[edit]

Language[edit]
  • Blocked:
  • Blocking:
  • Updates:
    • CX-VE work continue: saving, restoring.
    • cxserver now using readable and splitted registry files.
Collaboration[edit]


Parsing[edit]

  • New linter category coming up
    • html5-misnesting: This triggers when misnested tags behave different in Tidy vs. HTML5 (<span> is notably one of them).
  • Repeat update from last week as an FYI
    • Heads up for Parsoid clients (VE, CX, Flow, MCS)
      • <section> wrapping code is now out of WIP and in review ( https://gerrit.wikimedia.org/r/#/c/364933/ ) -- please test your code to make sure you can handle <section> wrappers. If necessary, you can pre-process the DOM to strip out <section> tags. Parsoid's output is guaranteed to preserve template wrapping semantics with / without <section> tags. Parsoid can also accept DOMs with / without <section> tags (for serializing back to wikitext).
      • We plan to switch Parsoid DOM output to use <figure-inline> tags instead of <span> for inline images ( https://gerrit.wikimedia.org/r/#/c/370227/ ) -- please test your code to make sure you can handle the new markup. VE can handle this.

Community Tech[edit]

  • Blocking: none
  • Blocked by: none
  • Report:
    • Currently populating ip_changes
    • Working on GlobalPreferences
    • HTML5 sections IDs are in stage 1 population

Services[edit]

  • Not attending
  • Blockers: none
  • Updates
    • All mobile traffic served from the new Cassandra 3 cluster exclusively
    • Preparing to test Parsoid with Cassandra 3

Technical Operations[edit]

  • Blocked:
    • Flow dumps speed issue still, waiting on Collab Team T164262
  • Blocking:
    • None
  • Updates
    • Resuming Asia DC work
    • Salt removal ongoing, almost fully done
    • Possibly fixed a long standing varnish issue with mailbox lags

Scoring Platform[edit]

  • Blocked by: none.
  • Blocking: Still blocking ORES deployment to the new cluster.
  • Updates:
    • Working on the statistics-derived thresholds changes, on the MediaWiki side now. This is a blocker to us releasing the next major version of ORES. Deployment will be messy since the new code breaks v1 of the API.

Search Platform[edit]

RelEng[edit]

Fundraising Tech[edit]

  • Quieting down error logs by fixing small bugs
  • Refining fraud detection
  • Handling more conflicts in CiviCRM contact deduplication
