Editor retention: Editing tools
In January, the team worked primarily on reviewing and cleaning-up the code deployed
in December. They spent time with their colleagues in the Parsoid team planning the next phase of development, which is aimed at making the VisualEditor the default editor for all Wikipedias from July 2013. The alpha version of the VisualEditor on mediawiki.org and the English Wikipedia was updated twice (1.21-wmf7
), fixing a number of bugs reported by the community and making some adjustments to the link inspector’s functionality based on feedback.
In January, the Parsoid
team did some Spring cleaning and bug fixing. The serialization subsystem was overhauled: it now features simpler and more robust separator handling. Selective serialization was rewritten to deal with content deletions. It also features DOM diff-based change detection that does not rely on client-side change marking. Support for non-English wikis and local configurations was also improved a lot, and will likely stabilize in the next weeks. The team also discussed and documented the longer-term Parsoid / MediaWiki strategy in the Parsoid roadmap
. The performance-oriented C++ port was deprioritized in favor of DOM-based performance improvements and HTML storage. The basic idea behind storing (close to) fully processed HTML is to speed things up by doing no significant parsing on page view at all. In the longer term, VisualEditor-only wikis can avoid a dependency on Parsoid by switching to HTML storage exclusively. Overall, the plan is to leverage the Parsoid-generated HTML/RDFa DOM format inside MediaWiki core to enable better performance and editing capabilities in the future.
Editor engagement features
This month, we stepped up development on the Notifications project Echo
and updated our first experimental release on mediawiki.org. Ryan Kaldari and Benny Situ improved the user experience for core features such as the badge, fly-out, all-notifications page and email notifications, and started developing new features such as bundling
and web preferences
. Luke Welling completed work on HTML email and started development of a more robust job queue
. Fabrice Florin led discussions about the Echo product plan, and new features
under consideration, while Vibha Bamba designed new components of the user experience. We plan to develop some of these features and notifications in coming weeks, and are aiming for a first release on the English Wikipedia by the end of March; in the meantime, you can try the current version
on mediawiki.org. We are also recruiting for a software engineer
to join our team and work with us on this and other editor engagement projects.
Flow entered the product design phase in early January. OPW intern
Kim Schoonover began user research
regarding how user-to-user talk pages are handled, and collected data about the difficulties that new (and existing) users have when using them. Engineering discussions started about potential back-end and scaling difficulties, the possible use of Wikidata’s ContentHandler
, and the evaluation of Wikia’s MessageWall. A plan for community engagement was proposed and accepted, with a consultation about the problems faced planned for early February, with experienced and newer users alike.
This month, our team updated Article Feedback v5
and discussed its release with communities in the English, French and German Wikipedias. Developer Matthias Mullie completed a major code refactoring, which is now being reviewed. He also developed a final set of new features
, such as simpler moderation tools and better filters, to be tested next month. Dario Taraborelli and Aaron Halfaker posted a feedback evaluation report, which suggests that about 39% of the feedback collected in their study can be used to improve articles (see also their other study results
). Oliver Keyes responded to community questions in a request for comments
about future deployments on the English Wikipedia, with a final decision expected next month. Fabrice Florin led product planning and discussed a possible deployment on the French Wikipedia
and with the German Wikipedia
, currently evaluating the tool in an ongoing pilot
with a vote expected in May. Once our development is complete and communities reach their decisions for each project, we expect to release Article Feedback v5 on a range of Wikimedia sites in coming months.
Editor engagement experiments
Editor engagement experiments
In January, the Editor Engagement Experiments team (“E3”) planned its goals for the quarter
, which ends in March. We also made progress on the following projects which are included in that plan.
First up, we launched guided tours
on the English Wikipedia, including a test tour to demonstrate the capabilities of the extension, and a tour associated with the “onboarding new Wikipedians
” (aka GettingStarted) project. In addition to tours created by the team, the extension
supports community-created tours. Note that unlike many other projects by the E3 team, guided tours are planned as a permanent addition to Wikipedia, with each tour implementation considered to be experimental. (For example: the “getting started” tour will be delivered via a split A/B test.)
While building guided tours, the team also A/B tested the Getting Started
landing page and task list, measuring the effect it had on driving new contributions. Several rounds of analysis were completed and published on Meta (round 1
, round 2
), with the conclusion that the onboarding experience is leading to small but statistically significant increases in new English Wikipedians attempting to edit, as well as saving their first edit. In addition to measuring the effects of the guided tour associated with this project, immediate plans are to redesign the landing page and add additional task types, to entice more new contributors.
Work also continued on refining the reliability and precision of the data collected from EventLogging
. In particular, we migrated EventLogging to a dedicated database, and began collecting server-side events in addition to client-side, to support work such as measuring account creations on desktop and mobile. January also saw the heavy use of the new User Metrics API
, in order to complete cohort analysis of onboarding users and for metrics reported at the Board presentation
on the Foundation’s year-to-date progress. Development of the API continues, and a public announcement is expected for early March. Last but not least, a call was put out for a part-time Technical Writer
to work on documenting both of these pieces of infrastructure.
2012 Wikimedia fundraiser
January marks the official end of the 2012 fundraiser. The team spent the entirety of the month cleaning up and recovering from the very successful months of November and December, auditing the donations, and writing tools that will help the team run continuous auditing in the future.
GeoData Storage & API
After its soft launch in December, GeoData was officially announced
this month. Work on improvements and bug fixing continues. The Special:Nearby page, which has been deployed to an experimental version of the site, represents the first major use of this feature on mobile projects. We hope to use it to help contributors identify articles in need of photos.
The push to get MobileFrontend
up and running on Beta Labs is well underway. We’ve also added test cases for Wikipedia Zero
and we are planning a community test event for Mobile Upload and Commons in February.
Mobile Web Photo Upload
This month, the mobile web team finished up work on the watchlist feature and kicked off a 3-month sprint on photo uploads. The focus in January was on developing basic uploading infrastructure: uploading images to Commons under a single Creative Commons license. We also built out the UX/UI design for a call to action on articles lacking images in the lead section. Through this workflow, users can upload an image to Commons and add a thumbnail of the image to the appropriate article on their local Wikipedia or sister project, in one simple step. We also developed a mobile uploads page where contributors can see their recent uploads and potentially donate more images from their mobile device to Commons. These features are currently live on the Beta mobile site and are set to be released to the full mobile site in February.
January marked the first month of the Apps team’s existence. Yuvaraj Pandian has started work with Brion Vibber on iOS and Android-based apps to upload photos to Commons. Both platforms are being developed concurrently and will have feature parity. Shankar Narayan joined us and and will be supporting the team for all design needs. While the first iteration of the Commons App isn’t scheduled to finish until February 8th, the team has already created two skeleton apps that can upload, share and show the user’s contributions. The team will be spending their next iteration tweaking workflows and styling the app. We also released new versions of the Wikipedia app on iOS and Android in order to bring it into compliance for legal privacy/disclaimer issues.
During January, Wikimedia was awarded a grant
in the Knight News Challenge for our work in expanding Wikimedia mobile projects. Part of this grant will be used for Wikipedia Zero and the SMS/USSD
projects to improve access to knowledge in the developing world. In addition, we’ve partnered with VimpelCom
to provide Wikipedia Zero to at least 100 million additional customers this year.
During January, we’ve begun to explore ways to reduce the memory and processor requirements of our J2ME app, to increase the number of phones that can use this application.
Wikipedia over SMS & USSD
We are finishing work on capturing the metrics from the SMS server to learn usage numbers and determine how many sessions are completed.
were deployed in January on a modified schedule, due to holidays and because of the data center migration. Deployments have returned to their usual fortnightly schedule.
was rewritten in early January. While this was primarily done to support the data center migration
, this was the first time ExtensionDistributor had received any signification attention since the migration to Git. The new version now utilizes the Github API to generate extension snapshots. We hope that the new version will be more reliable for users. SVN-based extensions are no longer supported, but this is not expected to impact many users since these extensions are largely unmaintained (all popular and active extensions have long since moved to Gerrit). As always, these extensions will remain in SVN should anyone still want the code.
Jan Gerber continues bugfixing and refining TimedMediaHandler, mainly focusing on operational improvements to make more efficient use of our server infrastructure.
Sam Reed helped the Wikidata deployment, deploying the Wikibase Client extension to Wikipedia in Hungarian, Hebrew, and Italian. Chris Steipp reviewed the Wikidata team’s work to extend AbuseFilter for use with structured data. Aaron Schulz worked with Daniel Kinzler on job queue improvements.
Wikivoyage officially launched
on January 15. Most of the Wikimedia Foundation’s involvement was completed in November, but some minor bugfixing was done in support of the official launch.
NFS for uploads/thumbnails has been unmounted from all Apache servers and the NFS back-end configuration was removed from MediaWiki; all files now only use Swift. A workaround has been added for the Swift back-end class when used with Ceph, so that temporary URLs can be used (for making video thumbnails for example). A Python script to copy files into Ceph has been run and is being worked on. Various issues have been reported in Ceph’s bug tracker and are being looked at by the developers.
Lua development was put on hold through the Ashburn data center migration. We’ve now resumed work on Lua, with Brad Jorsch and Tim Starling making more functions available in Lua that are currently already available in template parser functions.
A patch to allow moving the DB job queue to another cluster is under review. An experimental redis-based job queue patch also exists in gerrit.
Incremental architectural improvements
Code was merged to support more complex data structures (lists, sets) in memcached (with atomic updates).
Admin tools development
The team mainly focused this month on improving the AbuseFilter extension, which is now working on the Wikidata
site after support was added for other content types (as defined using ContentHandler
). There was some significant work done on blocking abusive proxies and abuse limits, and some additional progress made on global AbuseFilters, user renaming and the interface for Stewards to mass-lock user accounts
Security auditing and response
The team continued to respond to reported vulnerabilities, began a security review of fundraising extensions, and continued reviews of Wikidata features.
We started to schedule opportunities for community testing events
. Echo, AFTv5, and VisualEditor are all current candidates for testing. A week-long focus on VisualEditor’s support for non-Latin characters
uncovered at least one major issue causing data loss, and another one with tool-assisted Chinese input.
The main use for the Beta Cluster in January was to test git-deploy
. Zeljko Filipin continues to run regular tests there. Antoine Musso, Max Semenik, and Andrew Bogott are setting up MobileFrontend to run on Beta for testing purposes.
Antoine Musso worked with several MediaWiki extension authors to ensure that the unit tests for those extensions are run by Jenkins and that they work. He hopes to have all extensions that run on the Wikimedia production cluster fully operational by the end of February. Antoine also integrated PHP CodeSniffer
into our automated test runs.
Architecture and configuration for browser testing are now stable, and the focus shifted to increasing test coverage by making existing tests more extensive and covering new features. An example is the Math extension
, which was briefly broken after the data center migration. The team has also instituted a weekly pair-programming session every Friday.
Kraken (Analytics Cluster)
In January, we built automated data collection and analysis workflows for mobile page views by country by device, and we wrote Pig User-Defined Functions
for device detection using the dClass library
. We also migrated all our analytics repositories to the official Wikimedia github account
. We set up Riemann
for real-time cluster monitoring, and solved the packet loss issue that happened when storing data.
The team made performance improvements and added new visualizations. Bar, line, and geo plots can now be built ad hoc from arbitrary data. Evan Rosen’s Grantmaking and Programs dashboard was migrated to this new version of Limn. Current work includes a collaboration with the E3 team to provide visualizations, and development of a MediaWiki extension that will allow creation and editing of graphs.
This month, a first bugday was held
, targeting bug reports which had not seen any changes for more than one year, resulting in about 30 tickets being updated. In addition, some cleanup work (decreasing the number of unprioritized bug reports and going through open reports in “ASSIGNED” status for more than a year) took place. Andre Klapper worked on small Bugzilla code changes
and published initial information on Bugzilla usage per development team
. Community members were invited to join the MediaWiki Group Bug Squad
. Furthermore, some problems due to data center migration
were investigated, and it was discussed how to improve interaction on Bugzilla tickets that need handling by the Operations team (who mostly prefers to use the RT
Six Outreach Program for Women
interns started on January 3rd and will work full time until April. Mariya
is working on a discussion among third-party MediaWiki users
has completed the Bug Squad group proposal
and a first Bug Day. Priyanka
created a script
and plans to move to Git
is on schedule following her project plan
is learning about Flow
and the basics of interactive design as indicated by her mentor. Teresa
has completed a solid base
for her extension and is working on the main functionality. She hit a snag with her work environment this week, but is still on track with her proposed timeline. The Google Summer of Code 2013
page was created, a pre-planning discussion
started on wikitech-l, and LevelUp
matchmaking for the first quarter of 2013 is nearly done.
provided communications support
to the engineering team, notably around the data center migration
and associated banners
. He started to organize and clean up the MediaWiki version pages (like MediaWiki 1.21/wmf7
) to make them more useful for tech ambassadors
, by highlighting the most important changes, improving translatability and adding navigation. He also prepared and organized translations for the How to report a bug
and How to contribute
pages, to facilitate the involvement of volunteers who don’t necessarily communicate in English. Last, he created a Project:Calendar
to consolidate and centralize announcements for all events
, to make opportunities for participation more visible. Events around a particular topic (like QA, testing and bugs
) can still be selectively transcluded, using Labeled Section Transclusion
Volunteer coordination and outreach
The MediaWiki groups
and San Francisco
were officially approved by the Wikimedia Affiliations Committee
, and are the first Wikimedia User Groups
created. We helped the Editor Engagement
team organize a sprint to test Echo
, but our plans to collaborate further with the Editor Engagement and Mobile
teams were delayed; Quim Gil proposed a different approach
combining regular, time-based QA
and bug management
activities, in the form of QA weekly goals
. Two such events (non-Latin character testing in VisualEditor
and a review of old bugs
) happened in January, and more are scheduled. Heavy work was done with Chris McMahon to improve the top QA pages
, although some problems remain
. Template:MediaWiki News
is now manually synced with social media
, bringing fresh updates to the mediawiki.org homepage
page. Quim also took the lead on organizing the Wikipedia Engineering Meetup
January 17th. He prepared an intro to MediaWiki & Wikimedia tech contributions
, which he tested at FOSDEM
, designed to be reused by other presenters. Last, we confirmed that technical projects are eligible to Individual Engagement Grants
