Scrum of scrums/2017-09-27

= 2017-09-27 = contact: https://www.mediawiki.org/wiki/Wikimedia_Engineering

Callouts

 * Selenium Ruby framework deprecation (September) https://phabricator.wikimedia.org/phame/post/view/75/selenium_ruby_framework_deprecation_september/
 * Discovery: Maps: Figuring out what to do with code no one on the team is in charge of
 * New linter category coming up - html5-misnesting - which triggers when misnested tags behave different in Tidy vs. HTML5 (  is notably one of them).
 * 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
 * Please resolve comments that can be resolved in proposal of redesign of Scrum of Scrums meeting: https://docs.google.com/document/d/11gMloAKqtOJsKaDhpx_oIE8-vXvJs7pyLsDhqikaG08/edit?ts=59b0e080

Analytics

 * 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 * Removing outdated instrumentation of events from EventLogging that are now automagically available via eventbus, like “page create”.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/

Multimedia

 * 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

 * Blocked by: none
 * Blocking: none
 * Updates:
 * Finally released 5.6.1 with minor bug fixes ( https://phabricator.wikimedia.org/project/view/2898/ )
 * Continuing work on 5.7.0 ( https://phabricator.wikimedia.org/project/view/2899/ ) - Onboarding updates, Improved analytics, iOS 11 support, iPhone X support

Discovery

 * Putting together plan for automating portal deployments

Maps

 * nodejs 6.11 done
 * Figuring out what to do with code no one on the team is in charge of

Web

 * Turning off OCG. Investigating using chromium for printing.

Reading Infrastructure

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

Language

 * Blocked:
 * Request services in help to debug: https://phabricator.wikimedia.org/T173801 This again blocks cxserver deployment(s)
 * Blocking:
 * Updates:
 * CX-VE work continue: saving, restoring.
 * cxserver now using readable and splitted registry files.

Collaboration

 * Updates
 * RCFilters:
 * Features
 * - WLFilters: Live update and View newest
 * - RCFilters: Make 'lastRevision' filter include non-rev types
 * Bug fixes
 * - RCFilters: restore watch/unwatch link
 * - RCFilters: Make the interface not jump around while loading
 * - RCFilters: Don't grey out results area when initializing, unless there's a default saved query
 * Performance
 * - RCFilters: Cache ChangesListSpecialPage::buildChangeTagList
 * - RCFilters: Log performance data
 * - RCFilters: Don't load all of OOUI
 * - RCFilters: Make live update polling configurable

Parsing

 * New linter category coming up
 * html5-misnesting: This triggers when misnested tags behave different in Tidy vs. HTML5 ( is notably one of them).
 * Repeat update from last week as an FYI
 * Heads up for Parsoid clients (VE, CX, Flow, MCS)
 * 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 wrappers. If necessary, you can pre-process the DOM to strip out tags. Parsoid's output is guaranteed to preserve template wrapping semantics with / without tags. Parsoid can also accept DOMs with / without tags (for serializing back to wikitext).
 * We plan to switch Parsoid DOM output to use  tags instead of 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.

Scoring Platform

 * 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
