I'd like to draw some attention to the current outstanding release blockers.
From https://phabricator.wikimedia.org/tag/mw-1.38-release/, 8 tasks as queried from https://phabricator.wikimedia.org/maniphest/query/2YXgSfsvECyO/#R
1. T261329 Prepare Parsoid for MW 1.38 (ideally) https://phabricator.wikimedia.org/T261329 2. T265518 Move Parsoid ServiceWorker.php and extension/src/Config into core https://phabricator.wikimedia.org/T265518 3. T302117 ZeroConf VE for MW 1.38 https://phabricator.wikimedia.org/T302117
Component: Parsoid. Assigned to: WMF Content Transformation, formerly known as Parsing team.
If this is finished in master, it may be worth checking that relevant docs are up-to-date, and that relevant changes have made it to the branch in time (or are backported).
4. T275246 Populate rev_actor and rev_comment_id https://phabricator.wikimedia.org/T275246
Component: MediaWiki-Revision-backend. Assigned to: WMF Platform Engineering (@tstarling).
Originally planned for MW 1.36. Last year, change 684142 https://gerrit.wikimedia.org/r/c/mediawiki/core/+/684142 implemented the migration.
I moved it to the MW 1.39 milestone as this isn't something we can (nor should) rush through code changes alone. Per Tim's comment https://phabricator.wikimedia.org/T275246#7512017, we should add this to the installer/updater after we've succesfully migrated WMF's.
5. T288686 WVUI's TypeaheadSearch should work with a non-default `$wgScriptPath` https://phabricator.wikimedia.org/T288686
Component: Vector 22. Assigned to: Readers Web.
The new Vector 22 skin isn't yet used by default, but it currently hardcodes WMF-specific configuration and is bundled the release. There is an open patch pending review.
6. T294612 Raw HTML from Language Converters' title conversion displayed https://phabricator.wikimedia.org/T294612
Component: MediaWiki-Parser, MediaWiki-Language-converter. Assigned to: WMF Content Transformation, formerly known as Parsing team.
A regression reported October, that appears unsolved in prod (the linked example still displays raw HTML) and currently set to block the release.
7. T295187 Chinese conversion no longer work in the table of content https://phabricator.wikimedia.org/T295187
Component: MediaWiki-Parser, MediaWiki-Language-converter. Assigned to: WMF Content Transformation (@cscott).
This appears to be resolved from my very rudimentary testing.
8. T303029 Revert ParsoidSiteConfigInit hook creation https://phabricator.wikimedia.org/T303029
Component: Parsoid. Assigned to: WMF Content Transformation, formerly known as Parsing team.
Best, -- Timo
