Separate Language static methods/members into service(s)
Closed, ResolvedPublic
Actions

Description

One service we would want is LanguageFactory to replace Language::factory(). Two questions:

  1. Do we want to put all the other static methods on LanguageFactory, or put them in a separate service? The name suggests that it's to make Language objects, not a collection of generic Language-related methods. SpecialPageFactory does have lots of other special-page-related methods.
  1. Some of the static methods are unlikely to ever need to track state, such as isWellFormedLanguageTag(). Is it okay to leave these static? I would figure that we may as well make them instance methods as well, in case at some future date they incorporate state like caching, but it seems a bit excessive to force dependency on a service just for that.

Just FYI there's also a new LanguageCode class that has some static methods related to validating language codes, I'm not sure whether isWellFormedLanguageTag() (I haven't looked at the method yet, just guessing based on the name) would belong there.

Bumped to high, since this blocks T231866: Circular dependency when creating service! ContentLanguage, which we should fix for 1.34

Remaining non-deprecated public static methods on Language:

  • isWellFormedLanguageTag()
  • getCodeFromFileName()
  • getMessagesFor()
  • getMessageFor()
  • getMessageKeysFor()

The getMessage() ones call the deprecated method getLocalisationCache(), and should just be deprecated. The other two are simple pure methods that are unlikely to ever need state unless we need to add caching, at which point we could move them someplace else if we want.

I think this can be resolved as soon as the getMessage*For() methods are deprecated.
