in Wikibase/client/tests/phpunit/integration/includes/DataAccess/Scribunto/WikibaseLibraryInProcessEntityCacheTest.php:
provideLuaData is a non-static dataProvider function. It can't be made static without also changing files in other extensions:
- extensions/Scribunto
- tests/phpunit/Engines/LuaCommon/LuaEngineTestBase.php
- tests/phpunit/Engines/LuaCommon/LuaEngineUnitTestBase.php
- extensions/Capiunto
- tests/phpunit/output/BasicRowTest.php
- tests/phpunit/output/BasicTest.php
To avoid breaking CI, this change needs to happen in a multistep process across the affected repos.
