Upcoming events
There are many opportunities for you to get involved and contribute to MediaWiki and technical activities to improve Wikimedia sites, both for coders and contributors with other talents.

For a more complete and up-to-date list, check out the Project:Calendar.

Work with us
Are you looking to work for Wikimedia? We have a lot of hiring coming up, and we really love talking to active community members about these roles.

Announcements

 * Monte Hurd joined the Mobile engineering group as Software Engineer in the Apps team (announcement).
 * Brandon Black joined the Operations team as Dev/Ops Engineer (announcement).
 * Erik Bernhardson joined the Features team as Features Engineer (announcement).
 * Nischay Nahata joined the Features team as Features Contractor (announcement).

Technical Operations
Site infrastructure
 * Several large wikis were migrated to MariaDB, with positive results. A new class of redis servers were deployed in support of the migration of our asynchronous job queuing infrastructure from MySQL to redis, enabling us to better meet the demands of Wikidata and Echo. New file uploads are now being written to Ceph in Eqiad, in addition to Swift in pmtpa, in support of a potential migration. The current plan is to open up the Eqiad Ceph cluster for 'reads' the second week of May. Currently 'reads' are served by the Tampa Swift cluster.
 * With the core cluster migrated to Eqiad, we are now working on the miscellaneous server cluster. As part of the cleanup, we retired servers as well.

Data Dumps
 * New tools for import of partial or full content into a new wiki have been released. A step-by-step walkthrough of their use has been added to the documentation for users of the dumps on Meta.
 * True incremental dumps are now a GSOC proposal and several students have applied for this project.
 * The logging table XML dump on Wikidata was taking days to run, due in part to the high volume of edits there, much more than even the English Wikipedia. Most of those edits wind up being recorded as autopatrol in the log, making it already about half the size of the logging table for the English Wikipedia. Breaking up the database query into smaller batches works around the issue.

Wikimedia Labs
 * Work on tool labs is progressing nicely. 32 bots/tools have been added to the tools project. Most of the functionality of Toolserver should now be available in tool labs.
 * Database replication is still being worked on, but is progressing well. The pre-labs replication databases are being replicated to, and the Redactatron application has been finished, allowing us to mark tables as ok to replicate. Our current roadmap is for database replication to be accessible by the time of the Amsterdam Hackathon.
 * Instance creation performance greatly improved this month by replacing the generic Ubuntu cloud images with our own custom images that pre-installs and pre-configures most of what an initial puppet run would handle. Work on single-instance MediaWiki continued this month, making the initial MediaWiki installation more robust and handling a number of legal issues (such as showing the terms of use, using proper logos, linking to a proper privacy policy, etc.).
 * Work began on adding Ajax interactivity to the OpenStackManager interface. Currently changes are in for reboot and get console output actions for managing instances. A more reasonable project filter change using jQuery Chosen has been added as well.
 * Work on replacing glusterfs is mostly done. Two projects have been switched to use the new NFS server and the rest will be switched next month.
 * Work has begun on upgrading OpenStack from the essex to the folsom release. Our testing environment has been upgraded and production tests are currently ongoing. During the OpenStack summit, work was done to push the Moniker DNS application into OpenStack incubation to be added as a supported OpenStack project. Ryan Lane gave a talk during the OpenStack summit about the state of OpenStack's user committee, along with Tim Bell of CERN and JC Martin of eBay. Work on the user committee is in hopes of making OpenStack easier to use and upgrade, which should increase the frequency of updates in Labs.

Editor retention: Editing tools
VisualEditor  edit In April, the team continued their work on the major new features that will be added in the coming months. Our objective is for VisualEditor to be the default editor for all Wikipedia users, capable of letting them edit the majority of content without needing to use the wikitext editor, in July 2013. This means we have been focussed on four substantial areas of work: adding support for references, templates, categories and media items. During this time the main area of our work was editing around images, which is now designed and partially implemented in our experimental code, and around categories, which is almost complete and nearly ready for deployment. The deployed alpha version of VisualEditor was updated thrice (1.22-wmf1, 1.22-wmf2 and 1.22-wmf3), adding speed improvements, user interface improvements and work on the back-end to better support the new features, and fixing a number of bugs. We also were able to [//blog.wikimedia.org/2013/04/25/visualeditor-alpha-in-15-languages/ deploy the VisualEditor to fourteen more Wikipedias as an opt-in alpha] (and, later, Vietnamese Wikipedia too), which has let the community give us feedback on what works and is broken, and identifying language- and locale-specific issues we are now fixing. Parsoid  edit In April, the Parsoid team successfully deployed the cumulative work done over the last four months. This includes support for non-English wiki configurations, a rewritten serialization subsystem based on server-side DOM diffs, category link and basic template parameter editing support and a long list of fixes and improvements.

Several other features for the July release are on track. The specification for extensions containing templates and templates containing extensions were fleshed out and are currently being implemented. Similarly, our specs for images and thumbnails were vastly improved so that we will soon support full editing for all parameters.

We also improved our code quality and testing infrastructure.

In preparation for the July release, we did more benchmarking and capacity planning. A caching strategy that avoids overwhelming the API with requests was developed, hardware to run Parsoid was ordered and work on the implementation started.

Editor engagement features
Echo (Notifications)  edit In April, we deployed Notifications on the English Wikipedia and mediawiki.org. This first release aims to inform users about new activity that affects them on Wikipedia, such as talk page messages, page reviews, mentions, edit reverts or thanks. Ryan Kaldari developed a new feature that lets users mark all notifications as read, and updated the fly-out and archive page, based on designs from Vibha Bamba. Benny Situ completed the bundling feature and developed some of the first metrics dashboards, in collaboration with Dario Taraborelli. Luke Welling continued to develop HTML email notifications and a notifications mailbox. Fabrice Florin managed the product development and release of this notification system, and coordinated its socialization on the English Wikipedia with Oliver Keyes. We're also grateful to Steven Walling and Matt Flaschen from our E3 team for developing the Welcome and Getting started notifications. To learn more, visit the project portal, read the FAQ page and join the discussion on the talk page. Article feedback  edit In April, we deployed the final release version of Article Feedback v5 on the English, French and German Wikipedias. Developer Matthias Mullie updated the back-end software in order to re-enable the tool on the English Wikipedia, and fixed a number of bugs reported on the German Wikipedia. Fabrice Florin worked with Pau Giner, Oliver Keyes and community members to simplify the feedback page, as well as finalize feedback links, auto-archive and opt-in features. Learn more in this project update. To enable feedback on articles you watch on the English Wikipedia, simply add the 'Article Feedback 5' category to these pages. For more tips on how to use this version, visit the testing page, and let us know what you think on the Article Feedback Talk page. We are now wrapping up development for this project, and will collect community suggestions for the next few months to prepare for upcoming votes on the French and German Wikipedias later this year. Flow Portal/Project information  edit Design work continues and several discussions were had about what constitutes a minimum viable product for the first iteration of Flow. Brandon Harris is now building an interactive prototype to help describe multiple functions.

Editor engagement experiments
Editor engagement experiments  edit In April, the Editor Engagement Experiments (E3) team focused first and foremost on its account creation and login redesigns in MediaWiki core. The first phase of the launch invited editors and readers on all Wikimedia projects to test the new forms on an opt-in basis, to identify bugs and localization issues across our many wikis. We expect to release these as the default forms in May, pending any final blockers.

For the team's Onboarding new Wikipedians project, we completed quantitative analysis of the latest version of the GettingStarted landing page, and began prototyping a new landing page and navigation system for usability testing prior to further development and launch, which is expected in early May as well.

On the analytics and infrastructure front, the team handed off the product roadmap for the User Metrics API to the Analytics team and colleagues in the Grantmaking and Programs department. Ori Livneh, in support of the data analysis needs on the team, began work supporting a Foundation instance of IPython Notebook.

Last but not least, the E3 team held its second Quarterly Review session, and began work planning its next high-level goals for the April–June quarter.

Language engineering
Language tools  edit translatewiki.net home page development continues but was deprioritized due to development efforts around changes to the Universal Language Selector. The Mediawiki Language Engineering Bundle (MLEB) was released on April 30; updates include localization updates to Babel, Translate extension improvements, Xliff file format support, and easy access to message tools menu for the translation editor. Please note that MLEB is no longer compatible with Mediawiki 1.19. A Divehi language web font was also added. Specifications for the Language Coverage Matrix dashboard were designed. An internationalization test strategy was presented to and reviewed by the team. Milkshake <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Milkshake/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Milkshake" data-statuspage="Milkshake/status" data-entrydate="2013-04-monthly">The development team added a Divehi language web font to jQuery.webfont, and several contribution patches to jQuery.ime were merged. Redesign suggestions from the Product team on the Universal Language Selector (ULS) were reviewed by interaction designer Pau Giner and accepted by the development team. Changes include the launch workflow for ULS, as well as changes to display settings and font settings workflows for logged-in users. Development to reflect these changes is in progress and expected to be completed and tested for deployment in May. Language engineering communications and outreach <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Language engineering communications and outreach/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Language engineering communications and outreach" data-statuspage="Language engineering communications and outreach/status" data-entrydate="2013-04-monthly">Highlights of this month's communications and outreach activities by the team include UX testing with community members for ULS changes by Pau Giner, blog posts on team programs including the Language Mavens, translatewiki.net home page, translation UX improvements. The team also held office hours with the community as well as a successful bug triage focused on translate bugs.

Mobile
Wikimedia Apps/Commons <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Wikimedia Apps/Commons/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Wikimedia Apps/Commons" data-statuspage="Wikimedia Apps/Commons/status" data-entrydate="2013-04-monthly">The Wikimedia Commons Android app is available in the Google Play store, and we also added categorization support. Its iOS counterpart is available in iTunes. Wikipedia Zero <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Wikipedia Zero/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Wikipedia Zero" data-statuspage="Wikipedia Zero/status" data-entrydate="2013-04-monthly">We deployed Mobile Web's MobileFrontEnd-ZeroRatedMobileAccess decoupling code to production. We also started the next point release to support more object-friendly JSON-backed carrier preferences, updated carrier preferences, fixed UI button rendering bug, and documented configuration parameters. Last, we added content to wiki pages, and prepared for the migration of non-embargoed content to public wikis. Mobile design/Uploads <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Mobile design/Uploads/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Mobile design/Uploads" data-statuspage="Mobile design/Uploads/status" data-entrydate="2013-04-monthly">In April, we experimented with a login/signup call to action for logged-out users from our in-article upload feature. This resulted in a huge spike in new user contributions; however, the quality of the uploads was lower than anticipated, and the quantity of inappropriate uploads was a burden on the Commons community. In light of this, we disabled the login/signup call to action, allowing only existing Wikimedians to see and use the upload feature. We are still on target to reaching our fiscal year target of 1,000 unique uploaders a month and, when gated to existing users, the quality of the uploads has vastly improved: 3/4th of the files are retained on Commons, as compared to less than 1/4 when brand-new users were uploading. To create a more focused uploading workflow and let mobile uploaders discover more articles to illustrate, we also created a Nearby view on the beta site, showing users a list of articles near them and highlighting the ones that need images. We expect to release this to the full mobile web site next month.

MediaWiki Core
Auth systems <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Auth systems/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Auth systems" data-statuspage="Auth systems/status" data-entrydate="2013-04-monthly">During April, the team primarily focused on implementing SUL v2, which will fix issues that users are having with new security features in recent browser releases. SUL v2 is ready for testing and deployment is targeted for early May. In addition, the team worked toward a final design specification for OAuth and will begin working on that pending the successful deployment of SUL v2. Search <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Search/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Search" data-statuspage="Search/status" data-entrydate="2013-04-monthly">Code has been instrumented (and will soon be deployed) to log more data to allow root cause analysis of the spurious "Zero results" issue. Some log analysis was also done. The Puppet configuration on beta was updated to limit lucene-search-2 memory usage on Labs. MediaWiki 1.21/Roadmap <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="MediaWiki 1.21/Roadmap/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="MediaWiki 1.21/Roadmap" data-statuspage="MediaWiki 1.21/Roadmap/status" data-entrydate="2013-04-monthly">The 1.21 deployment cycle to Wikimedia wikis is complete, and the MediaWiki 1.21 tarball is being prepared for release, with a target release date of May 15. Mark Hershberger recently released MediaWiki 1.21rc4.

Git/Conversion <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Git/Conversion/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Git/Conversion" data-statuspage="Git/Conversion/status" data-entrydate="2013-04-monthly">We deployed a first iteration of a Bugzilla integration plugin, which provides notifications to Bugzilla when changes are made in Gerrit. We’ve increased the memory allocated to Gerrit, as well as deployed a couple of other stability fixes; both of these changes should provide some minor performance and stability improvements to users. Finally, we’ve deployed a new version of Gerrit that includes superior garbage collection support. This drastically improved the compression of repositories on-disk, which has resulted in a wide range of improvements for all users for all operations, from cloning to pushing to commenting on changes. Multimedia <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Multimedia/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Multimedia" data-statuspage="Multimedia/status" data-entrydate="2013-04-monthly">Differently-sized video thumbnails now only require one reference thumbnail (for the time position) to be generated. This helps to avoid expensive decoding to derive thumbnails. The Score extension was deployed on April 22nd. It allows users to create and document musical scores on Wikimedia sites. Wikidata deployment <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Wikidata deployment/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Wikidata deployment" data-statuspage="Wikidata deployment/status" data-entrydate="2013-04-monthly">After a minor delay due to some job queue and infrastructure migration work, Wikidata Phase II was deployed to all Wikipedia sites. This allows editors to reference and display content from Wikidata inside infoboxes. Lua scripting <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Lua scripting/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Lua scripting" data-statuspage="Lua scripting/status" data-entrydate="2013-04-monthly">Some bugs were fixed and internationalization changes merged this month; no major changes were made. The community continues to develop Lua-based templates, such as the citation templates on the English Wikipedia. Site performance and architecture <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Site performance and architecture/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Site performance and architecture" data-statuspage="Site performance and architecture/status" data-entrydate="2013-04-monthly">All job queues were migrated to JobQueueRedis off of the main DB clusters. Improvements were made to the category update queries to reduce lock exceptions that users often encountered when deleting files. This works via a new transaction callback hook added to the core database class, which can be used to resolve similar problems. Admin tools development <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Admin tools development/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Admin tools development" data-statuspage="Admin tools development/status" data-entrydate="2013-04-monthly">This month the team mostly worked on Single User Login finalisation, after which all user accounts will be global across all of Wikimedia's public wikis, allowing for cross-wiki notifications and better tools for editors. This will require all user accounts to be uniquely named and not conflict with other accounts. The global account renaming tool neared initial completion, and the global and local blocking based on XFF was finished and deployed. Work on designing a global CheckUser tool was postponed due to lack of resources. Security auditing and response <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Security auditing and response/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Security auditing and response" data-statuspage="Security auditing and response/status" data-entrydate="2013-04-monthly">We released the MediaWiki 1.19.5 and 1.20.4 security releases on April 15th.

This will help us with earlier detection of bugs introduced into master (such as ). Mark Bergsma and Antoine Musso refined the Varnish configuration for MobileFrontend, and further refined the configuration of the search functionality. Continuous integration <span class="plainlinks noprint mw-statushelper-editlink" style="margin: 0 0 0 1em; font-size:80%; background:#e4e4e4;" data-statuspage="Continuous integration/status" data-entrydate="2013-04-monthly"> edit <div style="margin: 0 0 0 2em;" class="mw-statushelper-entry" id="Continuous integration" data-statuspage="Continuous integration/status" data-entrydate="2013-04-monthly">In April, the Jenkins/Zuul platform encountered several issues such as the gating job running tests against the current version of the branch instead of the to-be-merged change. Antoine Musso solved several performances issues by using tempfs and a new SSD drive and upgrading Zuul to the latest upstream version.

Timo Tijhof overhauled the automatically generated MediaWiki documentation for JavaScript and PHP with Doxygen 1.7. He also fixed the duplicate test runs that happened in specific cases. Finally he set up QUnit tests for the VisualEditor extension; if this proves successful, QUnit runs will be generalized to all extensions.

Mark Holmquist improved the Jenkins jobs that track Parsoid regressions tests.

Finally, we've added linters for several languages: Python, Ruby and even Yaml. If your git repositories are missing a lint check, please contact us or file in a bug against Wikimedia > Continuous Integration.

On the technical side, Wikimedia Bugzilla's "See Also" field now also supports adding GitHub URLs and adding RequestTracker URLs, and the "Bugzilla Weekly Report" email sent to wikitech-l now includes a list of open issues with highest priority, plus more fine-grained statistics for the number of open tickets. Andre Klapper started drafting guidelines on Bugzilla administration and access restrictions, and updated the recommendations for checking Wikimedia forums (Village Pumps etc.) as sources of feedback on problems. Furthermore, he published an initial version of a Greasemonkey script that provides common one-click stock answers for Village Pumps where software issues might get reported first before being transferred to Bugzilla.

He supported QA and bug management events, organized a tech talk for 3 tech projects receiving Wikimedia grants, and completed the survey about best times for volunteering (which got 33 answers). He spoke at the Bay Area Linux User Group with Daniel Zahn, Rob Lanphier and Brian Wolff, and requested a proposal from Bitergia to automate the generation of Community metrics.

The Kiwix project is funded and executed by Wikimedia CH.


 * In April, we released for the first time Kiwix for Android. This version doesn't provide as many features as the desktop app, but it works well with all ZIM files. Two Kiwix developers will attend Wikimania and have started preparing for a a small hackathon, two presentations and a permanent booth.

Wikidata
The Wikidata project is funded and executed by Wikimedia Deutschland.


 * The team hit a big milestone with the deployment of the first iteration of phase 2 of Wikidata on all remaining Wikipedias (it had been enabled on 11 Wikipedias previously). Qualifiers were also enabled on Wikidata, making it possible to add additional information to certain data. Wikipedians are now able to make use of the data available on Wikidata in articles, allowing the data to be collaboratively collected, curated and used by all Wikipedias.
 * The team also fixed a few issues to make it possible to use Wikidata with Internet Explorer 8, and worked on the time datatype. Together with bot owners, they massively improved the time it takes for Wikidata changes to show up in the recent changes and watchlists on Wikipedia sites. The code and architecture got an external professional review; the reviewers were quite happy with the quality of the code base and gave useful tips for improvements.

Future

 * The engineering management team continues to update the Deployments page weekly, providing up-to-date information on the upcoming deployments to Wikimedia sites, as well as the engineering roadmap, listing ongoing and future Wikimedia engineering efforts.
