Next meeting on Oct 11 ** https://www.mediawiki.org/wiki/5_Minute_Demo#Recordings_and_Presenters * Parsoid Services (Core Platform) and Parsing team deployed code this week that implements HTML version (content) negotiation protocol alongwith a major version bump of Parsoid HTML from 1.8.0 to 2.0.0 ( https://www.mediawiki.org/wiki/Specs/HTML/2.0.0 ). As part of this, RESTBase + Parsoid will enforce the HTML version requested in the Accept header. If a version is requested that is different (^ semantics) than what is available in storage, RESTBase will ask Parsoid to get the appropriate version. If Parsoid cannot do that, it will return a HTTP 406. What does it mean for Parsoid clients? If you are requesting a really old version in your Accept header, you are very likely going to get a HTTP 406. If you request an older version (1.7 or 1.8), you will see an additional latency to your requests while Parsoid downgrades the HTML from the more up to date version. So, Parsoid clients should provide an accept header with the most up-to-date version of Parsoid HTML you can handle. Subsequently, you should update your code to handle the newer versions in a timely manner. A longer announcement and wiki docs will be coming out soon. == Audiences == === Contributors === ==== Community Tech ==== * Blocked by: * Blocking: * Updates: ** ==== Anti-Harassment Tools ==== * Blocked by: * Blocking: * Updates: ** ==== Editing ==== * Blocked by: * Blocking: ** Updates: ** ==== Growth ==== * Blocked by: * Blocking: * Updates: ** ==== Language ==== * Blocked by: None * Blocking: None * Updates: ** Content Translation v2 released! https://wikimediafoundation.org/2018/09/30/content-translation-version-two/ === Readers === ==== iOS native app ==== * Blocked by: * Blocking: * Updates: ** ==== Android native app ==== * Blocked by: * Blocking: * Updates: ** ==== Readers Web ==== * Blocked by: * Blocking: * Updates: ** Mobile website (MinervaNeue / MobileFrontend): *** Invest in the MobileFrontend & MinervaNeue frontend architecture https://www.mediawiki.org/wiki/Reading/Web/Projects/Invest_in_the_MobileFro… **** Add unit tests for util and mfExtend T203818 **** Bundle widgets and models with Webpack; enable headless Page and View tests T204867 T204786 **** Make test set up explicit T204885 **** Lint unsupported JavaScript in build products T203976 **** Move MainMenu click tracking schema from MobileFrontend to Minerva T204584 **** Merge skin option modules into a single ResourceLoader module and move enabled logic to client T167713 *** Page issues https://www.mediawiki.org/wiki/Reading/Web/Projects/Mobile_Page_Issues **** A/B test in progress T204609 **** Lots of cross-wiki QA and A/B test discussions *** Maintenance and bug fixes T205449 T202756 *** Advanced mobile contributions https://www.mediawiki.org/wiki/Reading/Web/Advanced_mobile_contributions **** Design and product continuing special pages work in Minerva ** PDF rendering (Proton) https://www.mediawiki.org/wiki/Reading/Web/PDF_Functionality *** Remaining work tracked in T186748 *** Html2pdf route should return promise T201158 T204055 T181623 *** Consistently represent asynchronous code execution T204055 ** SEO: where should Schema property 'sameAs' live?

Translations on hold until further notice

by Greg Grossmeier

tl;dr: Please refrain from adding new strings that require translations to MediaWiki and deployed extensions until further notice. Due to changes we are making in the way our translation systems process data we will be temporarily disabling the auto deployment of newly translated content until further notice. The goal of these changes will be to improve the evaluation of content submitted to our translation services. This means developers should not merge new translatable strings into MediaWiki Core nor Wikimedia deployed extensions until we re-enable the system. This is to prevent longer term issues where local wiki admins overwrite a string and thus prevent updates from new and improved translations. We apologize for any inconvenience this delay in service may cause and will alert you as soon as this maintenance is completed.

Discovery Weekly Update for the week starting 2018-10-01

by Chris Koerner

Hello again. It's been a while. This is the weekly update from the Search Platform team for the week starting 2018-09-17 through 2018-10-01. As always, feedback and questions welcome. == Discussions == === Search === * Implemented indexing statement values as part of main data in Wikidata, so that statement values are now searchable without special syntax [0] * Reindexed wikidata which also enables qualifier indexing [1] * Mathew worked on resolving an elasticsearch shard size alert by doing an in place reindex [2] * There was a lot of work done to investigate a brief outage of CirrusSearch (mw exception spike for api.php) [3], but it's resolved enough for now. * Gehel and others worked on refactoring puppet to support multiple elasticsearch instances on same node [4] * Erik worked on an issue where the text content of wiki page in search index can merge words making them unfindable [5] * Stas updated the search engine of Wikidata to enable searching by author name string [6] * David and Erik worked together on evaluating adding an image quality score to media search result ranking [7] * Stas added X-Search-Id to WikidataCompletionSearchClicks events [8] * David added a way to configure timeouts of autocomplete queries [9] * Erik upgraded saneitizer to constantly re-index documents [10] * David investigated why interwiki cache hit/miss was no longer reported (since 2017) and decided to drop the support for caching interwiki queries [11] * Mathew and Gehel worked on raising the alert level on disk space for old elasticsearch servers [12] * Erik worked to correct issues where the Cirrus MLT cache had a 0% hit rate on switchover [13] === WDQS === * Added new NTriples RDF dump (which makes it easier to do per-line processing) [14] * Internal cluster switched to Kafka events as change source, public cluster next [15] == Did you know? == * Different languages can have a different number of sounds they use; the set of sounds used in a particular language is called its “phonemic inventory”. [16] The numbers of sounds can range from 11 to over 140! Having more sounds than letters, or different sounds than the usual sound associated with a letter, can be the source of unusual orthographies and/or transliteration schemes—including "q" formerly being used as a vowel in Natqgu (now Natügu), a language of the Solomon Islands.

OOUI v0.29.2 released

by Volker E.

Hi everyone, last week we've released OOUI v0.29.0 and identified sequentially two issues on Beta-Cluster which we've addressed in v0.29.1 next day and v0.29.2 released yesterday. Bartosz Dziewoński took the chance and hardened the JS/PHP comparison test suite with former hotfix. Thanks to Pablo Grass of Wikimedia Deutschland and Petar Petkovic for help in identifying latter of those issues and Ed Sanders for instant fix! Key highlights of this release: - OOUI, similar to MediaWiki, now requires PHP 7 With this change we've also switched code to PHP 7 syntax in order to make code reusable between MediaWiki and OOUI (see below) - Deprecated CapsuleMultiselectWidget got dropped, which reduces widgets CSS by 8% percent after gzipping[0] Possible breaking changes: The following changes might cause breaking of your interface, please carefully consider if they affect your code. - Drop CapsuleMultiselectWidget, deprecated since v0.27.5. Use superior TagMultiselectWidget instead. - TextInputWidget: Drop support for `multiline: true`, deprecated in 0.22.2. Use MultilineTextInputWidget directly. - Consistently name document listeners[1] - Formally require PHP 7 -- Use PHP 5.6 variadic function syntax -- Use PHP 7 "\u{NNNN}" Unicode codepoint escapes[2] -- Use PHP 7 '??' operator instead of '?:' with 'isset()'[3] - Upgrade jQuery from 3.2.1 to 3.3.1 You can find details on additional new features & icons, code-level and accessibility changes, styling and interaction design amendments, and all improvements since v0.28.0 in the full changelog[4].

by Alexandros Kosiaris

Hello everyone, This is to inform you that there will be a datacenter switchover and switchback on the next few weeks. The timeline's are Services: Tuesday, September 11th 2018 14:30 UTC Media storage/Swift: Tuesday, September 11th 2018 15:00 UTC Traffic: Tuesday, September 11th 2018 19:00 UTC MediaWiki: Wednesday, September 12th 2018: 14:00 UTC Switchback: Traffic: Wednesday, October 10th 2018 09:00 UTC MediaWiki: Wednesday, October 10th 2018: 14:00 UTC Services: Thursday, October 11th 2018 14:30 UTC Media storage/Swift: Thursday, October 11th 2018 15:00 UTC For the duration of the switchover (1 month), deployers are kindly requested to refrain from large db schema changes and avoid deploying any kind of new feature that requires creation of tables. There will be a train freeze in the week of Sept 10th and Oct 8th. The net effect of the switchover and switchback for volunteers is expected to be some minutes of inability to save an edit. For readers, everything will be as usual. The tracking task for interested parties is https://phabricator.wikimedia.org/T199073 Regards, -- Alexandros Kosiaris <akosiaris(a)wikimedia.org>

MediaWiki 1.32 branch announcement

by Greg Grossmeier

Greetings! We are beginning the process of working on the 1.32 release of MediaWiki. The release is currently scheduled for Nov. We plan to create the REL1_32 branch on October 16 and to generate the first release candidate, so we will be requesting "pencils down" on October 15. In the meantime, if you have any open Phabricator tasks tagged with mw-1.32-release [0], please check to see if they are indeed blockers for the release. If not, please remove the mw-1.32-release tag from them. Conversely, if there are any blockers that are not tagged with mw-1.32.release, please tag them. Please feel free to reach out to me if you have any questions about this. We will be in the normal patch master + backport process from October 16 until the release in Nov. Thanks, Greg [0] https://phabricator.wikimedia.org/tag/mw-1.32-release/ -- | Greg Grossmeier GPG: B2FA 27B1 F7EB D327 6B8E | | Release Team Manager A18D 1138 8E47 FAC8 1C7D |
