Editor retention: Editing tools
In December, the VisualEditor team worked to continue the improvements to the stability and performance of the system, and to add new features. The deployed version of the code was updated three times (1.23-wmf6
). Most of the team’s focus was on major new features and fixing bugs. There is now basic support for rich copy-and-paste from external sources into VisualEditor, and a basic tool to insert characters not available on users’ keyboards. Work also continued on a dialog for quickly adding citation templated references, and on some major infrastructure changes, splitting out the core of VisualEditor from the MediaWiki-specific items like the transclusion editor.
In December, the relentless Parsoid team continued squashing bugs and incompatibilities; see our deployments page
for details. During the node 0.10 migration, we ran into some issues caused by changed garbage collector behavior, and rolled back to 0.8. We spent some time investigating and fixing this; initial testing on our round-trip testing setup indicates that this is now fixed.
Our testing infrastructure is now exercising the entire stack including the web server, which will help to make sure that we also catch issues in HTTP libraries before deployment.
We wrote several RFCs about embracing a service architecture
, PHP bindings for services
, a general-purpose storage service
based on our Rashomon revision store, and a public content API based on this
Part of the team worked on a new PDF rendering infrastructure using Parsoid HTML, node and PhantomJS. Part of the team has also been mentoring two Outreach Program for Women (OPW) interns.
In December, we deployed Flow to a few selected pages in production (Talk:Flow
on mediawiki.org) and collected feedback about the features and design to date from the community. The results of the feedback period are summarized at Flow/Research#Experienced Users
. Throughout the feedback period, we worked on implementing design changes – such as a more compact view of the board and different affordances for topic and post actions, as well as different visualizations of history information – based on the comments of users testing the software. We also began a straw poll about launching Flow as a beta trial in the discussion spaces of WikiProject Breakfast, WikiProject Hampshire, and WikiProject Video Games on English Wikipedia. Based on the outcome of these polls, we hope to deploy Flow to those pages in January.
In December, the Growth team spent time working on product development and research for upcoming Wikipedia article creation
improvements. First and foremost, the team fulfilled a request from the English Wikipedia community to launch the new Draft namespace
there. Pau Giner and others on the team simultaneously began design work on future improvements to drafts functionality (see blog post
), including recruiting for usability testing sessions.
Wikipedia Education Program
In December, we improved and fixed issues with the current Education Program extension, and continued preliminary work towards a new version of the software. We added a message on Special:Contributions about users’ participation in courses, fixed a bug involving course undeletion and tweaked related styling, addressed a breaking change in core, improved i18n (in collaboration with Language Engineering) and began work on notifications for course-related events. We also fleshed out more ideas about the new version and possible synergies with other existing and proposed functionality, and reached out to other teams for input on this.
We’ve continued our aggressive roll-out of Cirrus as a Beta Feature. You can search now 52% of pages including Commons and Wikidata via CirrusSearch. We’ve fallen back somewhat on our goal to make Cirrus the primary search engine. Right now, we only handle about 1.5% of search traffic. While we will be switching more wikis over to Cirrus as the primary search back-end in January, the theme of the month really is adding Cirrus as a Beta Feature to more wikis, including the English Wikipedia. We’re not sure how many wikis we’ll be able to add before we consider ourselves out of hardware space. We’re planning on 50% more servers in February so we’ll likely be able to finish adding wikis then.
Site performance and architecture
The team wrapped up the Puppetization of Graphite and its migration to Ashburn, and configured Travis CI to run MediaWiki’s test suite under HHVM on each commit to core. They also added an initial HHVM role for MediaWiki-Vagrant and re-wrote MediaWiki’s profiling data aggregator to be more performant. Prior to the rewrite, it was constantly saturated and would drop data; the rewrite reduced average CPU utilization by more than two thirds.
The team implemented performance fixes for CentralAuth to reduce the number of calls by anonymous users.
Wikimania Scholarships app
All critical functionality and several stretch goals were reached for the “final” version, which deployed to production on 2013-12-19. Chad Horohoe stepped in in the final days leading up to launch and helped save the i18n features that were scheduled to be scrapped due to time constraints. Siebrand Mazeland and the wonderful volunteers at translatewiki.net are providing translations at a rapid pace. Bryan Davis also put in some extra hours to clean up the look and feel of the application with a new Bootstrap-based theme. The application period for Wikimania 2014 will open at 2014-01-06T00:00:00Z and continue until 2014-02-17T23:59:59Z. The team will continue to monitor and support the product through the application period, and the subsequent review and approval process of the Scholarship Committee.
Security auditing and response
We continued to respond to reported security issues, and completed security reviews of Flow, the Wikimania Scholarships app, and the GLAM Wiki Toolset.
Admin tools development
The team made several small improvements, including log entries, the addition of global groups to Special:CentralAuth, and the addition of global edit count to Special:MultiLock.
Release & QA
In December, the latest and greatest version of MediaWiki was released, 1.22
. This was lead by Mark Hershberger and Markus Glaser, working as the MediaWiki release team, along with help from the Wikimedia Foundation Release and QA team (specifically Greg Grossmeier and Antoine Musso). Of course, this was only possible because of the great work by all of the MediaWiki developers.
The QA team, along with Multimedia team, is working on API level tests starting with UploadWizard. This is close to being done. Another API level testing activity is Parsoid, with help from VE and CI (Antoine) teams.

In December, the Quality Assurance team worked particularly closely with the Mobile team, both supporting automated testing and also helping fix issues with Beta labs and with Jenkins. We continued to work with the teams from Language engineering, VisualEditor, Flow, Multimedia, Wikidata, and Search, as well as participated in the Google Code-In event. We are in the process of creating new support not only for automated browser testing, but also for API testing, test data creation, and monitoring of both test and production environments.
Parsoid on the Beta cluster is now based on the
repository and is properly self-updating whenever a change is merged in that repository via a Jenkins job
. Beta labs played a key role in finding and fixing some significant errors that, in combination, were causing users to see 503 errors in production, particularly on large pages and for Mobile users. For one thing, some timeouts on the Varnish caches had been set too low. We had increased those for the text Varnish servers but had not done so for Mobile Varnish servers. A tricky bug was also causing parts of large pages to be parsed multiple times. Last, the browser tests that incurred the 503 errors should have been capable of ignoring them. Thanks to Beta labs, the Varnish server timeouts are now correct, the multiple-parsing bug is addressed and the browser tests for MobileFrontend are running correctly.
Besides ongoing regression testing of Wikipedia features in cross-browser tests, in December we made the first steps for new abilities like testing geolocation for Mobile tests, testing and monitoring upload ability in production, adding the ability to create test data via the API, running tests in PhantomJS on the WMF Jenkins server, and monitoring the Beta labs test environment for fatal errors.
Quim Gil and Andre Klapper continued to run and coordinate Google Code-In
for Wikimedia. Andre’s draft for a Bugzilla etiquette
received lively feedback and discussion. On the technical side, Daniel Zahn prepared the migration of bugzilla.wikimedia.org to WMF’s new data center
by turning the existing rudimentary Bugzilla puppet code into a puppet module
and automatically generating documentation on doc.wikimedia.org
. As part of this preparation, Daniel and Andre also eliminated nearly all Perl CPAN modules (in Bugzilla’s
subfolder) on the new server by using default distribution packages instead. Furthermore, Andre worked on a preliminary patch
to display some common queries on the Bugzilla front page.
Project management tools review
Andre Klapper and Guillaume Paumier kicked off an evaluation of Wikimedia’s project management tools
. Guillaume prepared a consultation page
with topics for stakeholders and improved it together with Andre. It will initially be sent to the teampractices
mailing list and individual stakeholders. To facilitate getting input, talking to individual stakeholders via Hangouts and holding an IRC discussion
are also considered.
Wikimedia’s first participation in the Google Code-In
program required a lot of dedication from the ECT members, and about a dozen of mentors and other contributors helping creating and reviewing tasks. Students completed about 200 tasks. The GCI inertia and the lessons learned will help us organize a better gateway for new contributors, which was a main reason for us to join this program. We also believe that the experience acquired will help us make future editions as successful with less work.
Round 7 of the FOSS Outreach Program for Women
started and all projects and on track so far:
We joined Facebook Open Academy almost at the last minute thanks to a reminder from developer Tyler Romeo. Six projects were accepted, which will be developed by teams of university students during the first half of 2014:
In December, Guillaume Paumier
‘s primary focus was on creating and assigning tasks for the Google Code-in
program, mentoring students and reviewing their work. They worked on writing discovery reports
, adding TemplateData
to widely-used Wikipedia templates, and converting manually-translated pages on mediawiki.org to pages using the Translate extension. Guillaume also continued to provide ongoing communications support
for the engineering staff, and assemble and publish the weekly technical newsletter
, which is now delivered across wikis using MassMessage
. Last, he compiled readability metrics
for all past issues of the newsletter, as well as translation and subscribers
Volunteer coordination and outreach
We reached all our goals for submissions at FOSDEM
in Brussels (February 1−2): a fully scheduled Wikis devroom
, a main track session (The Wikipedia Stack
) by Erik Moeller, and the Wikimedia stand
coordinated by Dimitar Dimitrov
. Our hiring process for a technical writer contractor
was unsuccessful. After screening dozens of candidates and interviewing several of them, our three final candidates declined for various reasons. Without time to hire a writer before the Architecture Summit 2014
, we decided to hold the search for now.
In December, Mark Holmquist and Gergő Tisza updated the beta version of the Media Viewer
, based on new designs by Pau Giner. This new version
now features next and previous arrows, as well as faster image load and an enhanced metadata panel, as shown on this demo page
Fabrice Florin managed product development, spearheaded the team’s Multimedia Quarterly Review meeting
, hosted more roundtable discussions
and presented a Multimedia Vision 2016
to get more community feedback about our goals, with help from volunteer Aaron Arcos.
Bryan Davis, Aaron Schulz and other team members helped Dan Entous and David Haskiya release a first version of the GLAM Toolset
for batch uploads by museum curators. We also started work on fixing bugs for the Upload Wizard, which we’ll aim to improve as our primary focus this quarter.
Last but not least, we are delighted to welcome Gilles Dubuc, who is joining our multimedia team
as senior software engineer. To discuss these features and keep up with our work, we invite you to join the multimedia mailing list
In late December, the Analytics team partnered with Operations to enable log delivery over Kafka (distributed message bus). All logs from the edge caches serving mobile traffic are now delivered via Kafka into a data warehouse on our Hadoop infrastructure. We’re seeing 3−4K messages per second, with a maximum of 8K/sec over Christmas. This is a significant step towards our goals of building an infrastructure that can be used for analysis of all of our page views.
The team added a small but important feature to Wikimetrics in December: the ability to authenticate against MediaWiki OAuth. This allows users to sign up for Wikimetrics without relying on a third party for authentication and is an early adoption of MediaWiki OAuth.
The team continues to spend a large amount of time on data quality. The primary effort in December was in isolating and fixing an error in WikiStats that inflated page views from July to December by a significant amount. The error was patched in early December and the statistics were recalculated. There were also issues with Wikipedia Zero traffic and an outage caused by a single point of failure in the legacy infrastructure.
Research and Data
This month, we kicked off a series of monthly research showcases as an opportunity for the team to share what we’re learning about Wikimedia editors and projects, and new features and programs the Foundation is rolling out. Aaron Halfaker presented research on anonymous editors
. The first showcase was targeted at an internal audience but we’re considering making future showcases open to anyone via a public stream.
the cause and impact of major over-reporting on page views in the last months of 2013. We filtered bogus traffic from the data, and published updated reports
We also continued work on metrics standardization
the rationale for this project and the results of the initial round of analysis we conducted.
This month also saw the completion of the third volume of the research newsletter
, which this year covered a total of 196 publications reviewed by volunteer contributors. A retrospective of research covered in the newsletter in 2013 will be published later in January.
