Editor retention: Editing tools
In June, the VisualEditor team completed the major new features that we prioritised over the past few months, in preparation for making VisualEditor available to most Wikipedia users in July. We have built an editor that is capable of letting users edit the majority of content without needing to use wikitext — text support, as well as adding and editing inclusions of references, templates, categories and media items. The deployed alpha of VisualEditor was updated four times as part of the transition to weekly deployments (1.22-wmf6
), with several mid-deployment releases as the code was developed to patch urgent issues. Part of this involved running an A/B test for new user accounts on the English Wikipedia, with half of the users getting opt-in to VisualEditor ahead of the wider release. Generally, there were a number of user interface improvements, and fixing a number of bugs uncovered by the community.
Early this month, we deployed Parsoid to the new cluster and started to track all edits and template / image updates from all Wikipedia sites, which is close to the full load we’ll see when VE is deployed to all of them. Our earlier optimization work paid off as the Parsoid cluster and the associated Varnish caches are handling the load very well. The extra load we put on the API cluster is low enough to not cause a problem. As expected, the VisualEditor deployment to the English Wikipedia hardly showed up in the load graphs.
Despite being very short-staffed this month (only two full-time developers), the absence of performance issues left us enough time for a lot more polishing before the VisualEditor release on July 1. As a result, the release went very well with clean diffs on almost all pages.
While more work is left to do, it is now clear that we have fundamentally achieved our goal of a clean translation between WikiText and HTML + RDFa. This does not only enable visual HTML editing, but also makes Wikipedia’s content easily accessible in a standardized format. It also opens up new opportunities for MediaWiki’s core architecture, which we’ll pursue this fiscal year.
Editor engagement features
In June, we released more features and bug fixes for Notifications on the English Wikipedia and mediawiki.org. Ryan Kaldari added a confirmation button for the ‘Thanks feature
‘, and updated notification fly-outs to show diff links
for talk page and interactive notifications, based on a design by Vibha Bamba. Benny Situ continued development of HTML Email notifications
and deployed a variety of feature updates. Erik Bernhardson developed a special ‘Suppressed’ content feature, while Matthias Mullie developed a range of new metrics dashboards
. Dario Taraborelli and Aaron Halfaker ran a week-long A/B test of new user activity
; results show that new users who received Echo notifications made more edits than those who did not, but their edits were reverted slightly more often. Fabrice Florin led the planning process for Notifications, as outlined in the 2013 roadmap
, and hosted a day-long roundtable discussion
to improve editor engagement features in collaboration with Wikipedia users (see Echo demo and Q&A video on YouTube
). Later this summer, we plan to start deploying Notifications on more wiki projects, starting with Meta and the French Wikipedia. To learn more, visit the project portal
, read the FAQ page
and join the discussion on the talk page
In June, we deployed final features and bug fixes for the Article Feedback Tool
(AFT5) on the English
Wikipedias. Matthias Mullie released an opt-in feature
to enable or disable feedback on a page, based on designs by Pau Giner and specifications by Fabrice Florin. In collaboration with Dario Taraborelli, Matthias also developed an updated set of metrics dashboards
showing how the new moderation tools are being used: for example, about half of moderated feedback is marked as ‘no action needed’, while about a tenth is marked as ‘useful’ (these results are generally consistent across different languages
). The team also supported a wider deployment of AFT5 on over 40,000 articles on the French Wikipedia, as well as a poll by the German community, which elected not to adopt the tool. Now that feature development has ended for this project, we plan to make AFT5 available to other wiki projects in coming weeks, as outlined in the release plan
. For tips on how to use Article feedback, visit the testing page

Editor engagement experiments
Editor engagement experiments
In June, the Editor Engagement Experiments (E3) team continued work on its experiments related to onboarding new Wikipedians
, and launched several new extensions to Wikimedia projects.
First, the new Campaigns extension
was added to all wikis. This analytics tool helps identify internal or external sources of new registrations, by adding a “campaign” name to the signup page URL. This month, E3 began running campaigns to learn about how many anonymous editors sign up on the top 10 Wikipedias, as well as how many sign up via the invitation to “Join Wikipedia” on the login page (see the list of active campaigns
and analysis). Another piece of analytics infrastructure by the team is the new CoreEvents extension
, which houses logging of MediaWiki core activity, like preference updates and page saves across all projects.
For the Getting Started
project, the team conducted usability testing (see results and documentation
) of new designs. E3 also refactored and refined the guided tours
extension in June, including adding usability enhancements like new interface animations, support for community tours, and bug fixing. The team also planned and began work on an experiment to deliver guided tours
to all first-time editors.
The team also assisted with A/B testing and research for VisualEditor
before its July 1 launch date, assisting with experimental design, EventLogging instrumentation, and other work. After the VisualEditor launch, E3 started a week-long micro-survey of newly-registered users
on English Wikipedia, to give us a first systematic look at the gender diversity of those creating accounts.
2012 Wikimedia fundraiser
The initial work on the Adyen payments gateway was finally completed and deployed to production, though we have not yet used the gateway in a campaign. Plans for a mobile fundraising campaign and workflow continued to move forward: We expect to do the first mobile-targeted campaign in mid to late July. Some last-minute tweaking was done to the payments cluster in preparation for the resumption of continuous fundraising on July 1, coinciding with the start of the fiscal year. Payments listener (thulium) deploy was completed, db1013 was moved into the firewalled fundraising cluster and rebuilt as a fundraising QA server, and work continued on the new CiviCRM server (barium). Fundraising backups were overhauled.
In June, the Platform Engineering group switched to a weekly deployment cycle
for MediaWiki to the Wikimedia Foundation servers. This means that we have almost halved our previous cycle of 2 weeks. As such, we are progressing through wmfXX versions of MediaWiki at a faster rate now. In June, MediaWiki versions 1.22-wmf6 through wmf9 were branched and deployed.
Chad Horohoe and Christian Aistleitner upgraded our Gerrit instance from a pre-release version of 2.6 to a pre-release version of 2.7 on the last week of June. They’ve additionally published a new version of the Bugzilla/Gerrit integration plugin. Details about new functionality can be found in the Gerrit 2.7 draft release notes
In June, we started expanding our multimedia team: Fabrice Florin joined as product manager, and Brian Wolff began a summer contract as software engineer. We started work on improving the display of images in galleries and are now planning our next development steps in consultation with community members. Some of the first features under consideration include file curation and feedback tools, as well as media viewers, new video formats and other platform improvements, to be prioritized based on user feedback and technical feasibility. We are also recruiting for two more positions: a multimedia systems engineer
and a senior software engineer
. Please spread the word about this unique opportunity to create a richer multimedia experience for Wikipedia and MediaWiki sites!
Admin tools development
In June, the team worked on making the last changes to enable global AbuseFilter rules, and on the global account renaming tool. Some additional work was done on Single User Login finalisation
, which will mean that all user accounts will be global across all of Wikimedia’s public wikis, and so allowing for cross-wiki notifications and better tools for editors.
Work has pretty much shifted from supporting MWSearch/lsearchd to investigating and implementing Solr. Nik Everett and Chad Horohoe have begun writing an extension
to implement Solr searching for MediaWiki, and we’ve gotten a lot of the initial basic functionality completed. Peter Youngmeister and Andrew Bogott will be handling the operations tasks for the new setup. Initial operations tasks will involve packaging Solr 4 and working with Chad to puppetize the whole design. Additionally, we’re going to do some investigation into ElasticSearch, as it’s been suggested as an alternative to Solr.
In June, the team worked with the Wikimedia Foundation’s user experience team to improve SUL2. The improvements were pushed to test wikis on July 1, and will be rolled out to other wikis in July. Implementation of OAuth is well underway, and planned for roll-out in July as well.
A Labs instance of MediaWiki running on HipHop is now available at http://hhvm.wmflabs.org
Security auditing and response
The team continued to respond to reported security issues, and gave security-oriented tech talks on emerging DoS techniques and using OWASP’s ZAP tool for vulnerability scanning.
This month saw a QA focus on automated browser tests. Besides creating new tests and new builds, and reporting issues identified by tests, we conducted a training session in San Francisco to create automated tests for the Wikilove feature. We continue to support all WMF software development projects, with the VisualEditor being a particular focus in June.
Max Semenik wrote a script to synchronize CSS from production on beta. Steinsplitter and Antoine Musso fixed the AbuseFilter configuration to have a global list of filters on the labswiki
. Filters should be configured there and will be used by all the wikis. The PHP fatal errors catched by the wmerrors extension are now sent to the beta udp2log instance. That will largely improve our troubleshooting process.
Timo Tijhof and Antoine Musso triaged continuous integration bugs. Antoine has setup a Jenkins slave and migrated most jobs on it. It will be very easy to add new servers.
This month, the QA team added new browser tests for UniveralLanguageSelector and for Mobile (contributed by the Language engineering and Mobile engineering teams, respectively), as well as browser test contributions from volunteers. We created new builds in Jenkins to run browser tests against IE10. We created tests for VisualEditor, including some with our intern with the Outreach Program for Women.
We made significant progress with our preparations for replacing udp2log with Kafka in our logging infrastructure. The C library librdkafka
has now support for the 0.8 protocol, there is a first version of varnishkafka
ready that will replace varnishncsa, the Apache Kafka project released their first beta of Kafka 0.8, and we have a Debianized
version. We keep on adding new metrics
and alerts to monitor all the different parts of the webrequest dataflows into Kraken. We expect to keep making improvements in the coming months, until we have a fully reliable data pipeline into Kraken. We also continued our efforts of moving Kraken out of beta: we puppetized Zookeeper
, and the Hadoop client nodes for Hive, Pig and Sqoop
. We started reinstalling the Hadoop Datanode workers with a fully puppetized Hadoop installation; so far, we have replaced 3 nodes, and we’ll replace the other seven in the coming weeks. Last, we enabled Jenkins continuous integration for the Grantmaking & Evaluation dashboards.
Analytics Visualization, Reporting & Applications
This month, we completed the end-user documentation
of UserMetrics (v1). We rebranded UserMetrics as Wikimetrics, and we will slowly start to use that as the new name when referring to UserMetrics v2 or UserMetrics replatforming. We focused on laying out the foundation of Wikimetrics: a new database design, a new job queue design and lots of unit tests. In addition, we started working on porting over some of the features of UserMetrics v1 (like the ‘namespace edits’ metric and UI components), we added user roles (so users can only see their own metrics) and authentication using OAuth. Last, we fixed some minor issues in UserMetrics v1, among which handling of user names with comma, single and double quotes.
We delivered many following analyses in June, including one of Arabic cohort using UMAPI v1. Erik Zachte provided an analysis of Commons uploaders, and we provided the Wikipedia Zero team with a number of datasets to help them in tracking adoption of the Wikipedia Zero project across the globe. We supported the VisualEditor and Editor Engagement teams with experimental design, data modeling and data analysis for two controlled experiments: a test of the impact of impact of notifications
and a first test
of the impact of Visual Editor on new contributors. The tests were carried out in June and the reports are being updated with the results of the analysis. We started using the EE-dashboard instance on Labs to host dashboards related to editor engagement projects, that were previously hosted on the Toolserver (see the metrics
dashboards for the English Wikipedia). Last, we worked with the Features engineering team to expand MediaWiki’s instrumentation and collect data on cluster-wide user preference changes
and edit-related events
to support VisualEditor analysis.
published the Bugzilla administrator policy
and documented for which specific tasks
Bugzilla admin rights are actually needed (which might be also helpful for other projects using Bugzilla). He started publishing weekly “Bugzilla tips and best practices”
blog posts and reproposed introducing a “PATCH AVAILABLE” status
in Bugzilla (as requested by several developers at the Amsterdam Hackathon) whilst work is ongoing to fulfill prerequisites. On the code side of Bugzilla, a new Bugzilla frontpage
went live, providing useful links. Furthermore, the misleading term “login” was replaced by “email address”
, it is now possible to set the “Assigned” status directly
when filing a new bug report, and smaller issues with the “Weekly Bugzilla Report” email sent to the wikitech-l mailing list were fixed. In Bugzilla’s taxonomy, open tickets in the dormant “Wiktionary tools” product were retriaged and the product closed for new bug entry, and Security-related components in Bugzilla were reorganized after a meeting with the Wikimedia Foundation’s security engineer.
The 20 Google Summer of Code
and the 1 Outreach Program for Women
interns have completed the bonding period
(with 3 exceptions, 2 of them justified) and they are now working on their projects. One OPW accepted candidate declined her participation due to a job offer. Monthly status updates are available for these projects:
We also met with SocialCoding4Good, who are relaunching their activities, and we refreshed the Wikimedia page. We expect this to become a regular channel for new technical contributors working in corporations with social/training programs.
In June, work on this topic mostly focused on perennial activities like Tech news
and ongoing communications support to engineering staff, as Guillaume Paumier
was lent to the VisualEditor deployment effort, working on communications, documentation and liaising with the French Wikipedia.
Volunteer coordination and outreach
The decision of focusing on fewer activities better executed and based on demand seems to be working out, although it’s too soon to confirm the trend. Browser test automation is the number one priority to recruit new contributors, and any help to succeed here is welcome. We created the QA mailing list
as an umbrella to host people and discussions focusing on software quality assurance in all its aspects. We have more than 40 subscribers and an initial flow of activity. We had a successful first Browser Test Automation Workshop
, with 40 participants in San Francisco and a few more online; we will iterate on this model. We have also helped organizing a Tech Talk on Attack vectors & MediaWiki and OWASP ZAP
, and the upcoming Solr-based Search
. The project to get automated community metrics
based on vizGrimoire
and provided by Bitergia
has been approved, and a first prototype can be seen at http://korma.wmflabs.org
. The project starts effectively on July 1 and includes a one-year period of maintenance. We agreed with the Analytics
team that they will assume the responsibility of this area during this period.
