Start integrating for MediaWiki for production early
Satisfies the need for a build step
Current status: l10n cache rebuilding updates. Currently depends on a full MediaWiki installation. Did a deep dive on rebuildLocalisationCache.php with xdebug.
Clears resourceloader cache as part of rebuild, but is likely incorrect since we update Wikiversions *after* l10n update
Scap purges cache for resourceloader as well post update -- that seems correct
removing resourceloader purge from rebuildLocalisationCache removes the need for a database connection
the next step is localisation hooks, but no production extensions use those hooks
deprecating those hooks, removing the resourceloader clearing, makes the l10nupdate much faster (hopefully), but it's a deep rabbithole
Feedback for image building
Scratch images in registries to integrate images later on
Process is database independent if we remove the ResourceLoader cache clear (doesn't seem like a good thing to do in that process anyhow)
No production-deployed extensions actually implement the two hooks defined by LC rebuild
These things mean it may be more possible to factor out LC rebuild from MW into a separate/faseter (maybe non-MW-PHP specific) process and compile LC files earlier in an MW image building pipeline
Done they do :)
