User style to reduce Gerritbot comments on Phabricator
by Bartosz Dziewoński 08 Jan '26

08 Jan '26

Do your eyes glaze over when trying to make sense of Phabricator tasks with a long and troubled history of patches? Do you struggle to find the real people in the sea of automated bot comments? I've made myself a user style to compact the Gerritbot comments on Phabricator. You might like it too: https://userstyles.world/style/13140/wikimedia-phabricator-reduce-gerritbot… (See screenshots and installation instructions there.) -- Bartosz Dziewoński

Struggling with Online Classes? Here's a Reliable Help Option!
by course fpx 19 Nov '25

19 Nov '25

Hey everyone, I’ve noticed a lot of students (including myself) struggling with the pressure of online classes, deadlines, and quizzes — especially with platforms like Capella FlexPath, WGU, and others. If you're overwhelmed, there’s a service I recently came across called Online Classes Help. They assist with everything from discussion posts and assignments to full course completion. Super helpful for those juggling jobs or other responsibilities! Whether you need one-time help or ongoing support, this could really reduce your stress and help you maintain a good GPA. Just make sure to use it ethically — as a support tool, not a shortcut! Has anyone else tried such services? Would love to hear your experiences. Cheers! fpr more info :https://coursefpx.com/online-class-help/

Forthcoming maintenance to irc.wikimedia.org - Moving to ircstream
by Moritz Mühlenhoff 30 Sep '25

30 Sep '25

Hi all, we're moving irc.wikimedia.org to a new infrastructure [1]. This service is unrelated to the IRC network (Libera) we use for real time discussions. Instead irc.wikimedia.org is an IRC service for broadcasting recent changes events from public Wikimedia wikis to be used by various bots connected to per-wiki IRC channels. irc.wikimedia.org should not be used for any new bots (which should rather use Eventstreams[2]), but we still have various important bots relying on the legacy IRC-based infrastructure. The current setup is full of technical debt and ultimately based on a patched version of a very old release of ircd-ratbox with a relay service written in Python 2. We are replacing it with a modern standalone implementation in Python, which broadcasts IRC notifications in a format compatible to what is currently in use by the legacy setup: https://github.com/paravoid/ircstream Last week during the SRE Infrastructure Foundations hackathon the ircstream production setup was created. All our tests have been successful, so on Thursday October 10 at 08:00 UTC we'll switch the irc.wikimedia.org DNS name to the new setup. No changes are needed to any bots, but if you run into any issues after the switch, please notify us in the #wikimedia-sre-foundations IRC channel or leave a note at https://phabricator.wikimedia.org/T376014. Cheers, Luca, Simon and Moritz Footnotes: [1] https://wikitech.wikimedia.org/wiki/Irc.wikimedia.org [2] https://wikitech.wikimedia.org/wiki/Event_Platform/EventStreams_HTTP_Service

Maintenance scripts are moving to Kubernetes
by Reuven Lazarus 23 Jul '25

23 Jul '25

Hi all, With MediaWiki at the WMF moving to Kubernetes, it's now time to start running manual maintenance scripts there. Any time you would previously SSH to a mwmaint host and run mwscript, follow these steps instead. The old way will continue working for a little while, but it will be going away. What's familiar: Starting a maintenance script looks like this: rzl@deploy2002:~$ mwscript-k8s --comment="T341553" -- Version.php --wiki=enwiki Any options for the mwscript-k8s tool, as described below, go before the --. After the --, the first argument is the script name; everything else is passed to the script. This is the same as you're used to passing to mwscript. What's different: - Run mwscript-k8s on a deployment host, not the maintenance host. Either deployment host will work; your job will automatically run in whichever data center is active, so you no longer need to change hosts when there’s a switchover. - You don't need a tmux. By default the tool launches your maintenance script and exits immediately, without waiting for your job to finish. If you log out of the deployment host, your job keeps running on the Kubernetes cluster. - Kubernetes saves the maintenance script's output for seven days after completion. By default, mwscript-k8s prints a kubectl command that you (or anyone else) can paste and run to monitor the output or save it to a file. - As a convenience, you can pass -f (--follow) to mwscript-k8s to immediately begin tailing the script output. If you like, you can do this inside a tmux and keep the same workflow as before. Either way, you can safely disconnect and your script will continue running on Kubernetes. rzl@deploy2002:~$ mwscript-k8s -f -- Version.php --wiki=testwiki [...] MediaWiki version: 1.43.0-wmf.24 LTS (built: 22:35, 23 September 2024) - For scripts that take input on stdin, you can pass --attach to mwscript-k8s, either interactively or in a pipeline. rzl@deploy2002:~$ mwscript-k8s --attach -- shell.php --wiki=testwiki [...] Psy Shell v0.12.3 (PHP 7.4.33 — cli) by Justin Hileman > $wmgRealm = "production" > rzl@deploy2002:~$ cat example_url.txt | mwscript-k8s --attach -- purgeList.php [...] Purging 1 urls Done! - Your maintenance script runs in a Docker container which will not outlive it, so it can't save persistent files to disk. Ensure your script logs its important output to stdout, or persists it in a database or other remote storage. - The --comment flag sets an optional (but encouraged) descriptive label, such as a task number. - Using standard kubectl commands[1][2], you can check the status, and view the output, of your running jobs or anyone else's. (Example: `kube_env mw-script codfw; kubectl get pod -l username=rzl`) [1]: https://wikitech.wikimedia.org/wiki/Kubernetes/Kubectl [2]: https://kubernetes.io/docs/reference/kubectl/quick-reference/ What's not supported yet: - Maintenance scripts launched automatically on a timer. We're working on migrating them -- for now, this is for one-off scripts launched by hand. - If your job is interrupted (e.g. by hardware problems), Kubernetes can automatically move it to another machine and restart it, babysitting it until it completes. But we only want to do that if your job is safe to restart. So by default, if your job is interrupted, it will stay stopped until you restart it yourself. Soon, we'll add an option to declare "this is idempotent, please restart it as needed" and that design is recommended for new scripts. - No support yet for mwscriptwikiset, foreachwiki, foreachwikiindblist, etc, but we'll add similar functionality as flags to mwscript_k8s. Your feedback: Let me know by email or IRC, or on Phab (T341553 <https://phabricator.wikimedia.org/T341553>). If mwscript-k8s doesn't work for you, for now you can fall back to using the mwmaint hosts as before -- but they will be going away. Please report any problems sooner rather than later, so that we can ensure the new system meets your needs before that happens. Thanks, Reuven, for Service Ops SRE

Watchlist
by יגאל חיטרון 31 May '25

31 May '25

Hi. Was there any change of code right now? Saturday 19:00 UTC. Because I suddenly get a huge hole in my Watchlist, because of client-js .mw-rcfilters-collapsed.mw-special-Watchlist .mw-rcfilters-head { min-height: 220px; } I can, of course, add mw.util.addCSS('.client-js .mw-rcfilters-collapsed.mw-special-Watchlist .mw-rcfilters-head {min-height:initial !important}') but I'd really be glad to know from whence it came. Thank you.

OpenSearch can now be used in Wikimedia CI
by Jakob Warkotsch 28 May '25

28 May '25

Hi everyone, The CI MediaWiki jobs can now have OpenSearch enabled. This is useful for testing anything involving advanced search functionality provided by CirrusSearch. The first CI job to make use of this feature is the Wikibase api-testing suite (by setting QUIBBLE_OPENSEARCH=true via a config patch <https://gerrit.wikimedia.org/r/c/integration/config/+/1150758>). As a result we are now able to properly end-to-end test its search endpoints. At the moment, OpenSearch is only included in Quibble images 1.14.1+ based on Debian Bullseye. The work for this was largely tracked in T386691 <https://phabricator.wikimedia.org/T386691>. Cheers, Jakob -- Jakob Warkotsch Software Developer Wikimedia Deutschland e.

Upcoming Codex 2.0 release
by Anne Tomasevich 27 May '25

27 May '25

The Design System Team (DST)[0] is preparing to release the next major version of Codex, the design system for Wikimedia. Codex has evolved significantly since the first major version release in late 2023: expanding the toolkit with a number of new components[1], tokens[2] and icons[3], introducing alternative color modes[4], adding a proper i18n system[5], refactoring components to be compatible with native browser validation[6], supporting the creation of a PHP implementation of the component library[7], refreshing the documentation, and (finally) getting a unique logo. With the upcoming introduction of a revised typography scale and customizable font modes[8] along with a handful of other breaking changes, DST has determined this to be an appropriate time for another major version release. ==== Timeline ==== DST plans to first release a release candidate (rc) of version 2.0.0 that will include all known breaking changes. It is anticipated that only one rc version will be released, but if major issues are discovered, there will be additional rcs until the build is considered stable enough to be the official major version. - v2.0.0-rc.1 will be released on 29 April 2025 and ride the deployment train the week of 5 May 2025 - v2.0.0 will be released on 13 May 2025 and ride the train the week of 19 May 2025 ==== Breaking Changes ==== Codex 2.0 will include a number of breaking changes that need to be addressed in downstream code to avoid compatibility issues. These are detailed in full along with guidance on how to prepare for the release at https://www.mediawiki.org/wiki/Codex/Release_Timeline/2.0#Breaking_changes. If you are using Codex for a feature actively deployed in Wikimedia production, please check to see if the breaking changes apply to your code. DST has already opened Phabricator tasks for known areas that need to be updated based on codesearch but this is likely not comprehensive. Thank you to everyone who has contributed to the development of Codex throughout its 1.0 lifespan! We look forward to seeing its use in Wikimedia projects continue to grow as it further evolves through this next major iteration.
