On this REL1_42 backport, CI is failing (full console) with lots of errors like this:
1) Wikibase\Client\Tests\Integration\Hooks\EchoNotificationsHandlersTest::testWikibaseHandleChange Error: Class "Wikibase\Repo\WikibaseRepo" not found /workspace/src/extensions/EntitySchema/src/EntitySchema.ServiceWiring.php:33 /workspace/src/vendor/wikimedia/services/src/ServiceContainer.php:447 /workspace/src/vendor/wikimedia/services/src/ServiceContainer.php:411 /workspace/src/includes/MediaWikiServices.php:356
I assume this is an unintended consequence of T367156 – we’re pulling EntitySchema into the Wikibase client-only CI job, even though EntitySchema only supports client-only Wikibases since REL1_43.
MediaWiki 1.42 is supposed to be supported until June 2025, so it would be nice if we could fix this.
