Also make a few changes to the functions available. SpecialPageFactory::resolveAlias() now takes an optional subpage and returns array(<name>,<subpage>). Similarly merge getPage() and getPageByAlias(). There were many examples of (extensions particularly) making dubious assumptions about the presence or absence of subpages or canonical-ness.
I didn't deprecate SpecialPage::getTitleFor() as it's got over six hundred calls. I'm rather undecided on the best position of getPage()/executePath(). Although the latter needs cleanup anyway.
This fixes the more general problem that the imageinfo returned with stashed uploads was inaccurate, since it was relying on
code that only worked with non-stashed files.
So, I had to:
- move the ApiQueryStashImageInfo module into core. Which others had asked for anyway, and was anticipated sometime later.
- add lines to AutoLoader and ApiQuery to accomodate the new module
- add an ugly if/then to UploadBase -- based on the type of uploaded file, it will use a different API module to simulate a getImageInfo call.
I left a TODO that this situation wasn't ideal, but the way things are now, imageInfo is constructed by the API modules, when it should probably
really be the File modules. Then the API can wrap that info into various formats.
- add a few new lines to the tests to check imageinfo information in both regular and stashed upload files
* Introduced a "cache mode" concept to simplify the header generation code, and to avoid odd results when conflicting cache header requests are received from submodules, or at least to formalise the handling of such cases.
* Made the cache mode private by default, so that code written in ignorance of caching tends to be safe. If different query modules are used in a single request, private caching is preferred over public caching.
* Removed the "must-revalidate" option from all CC headers, this is really specific to page views with a hacked squid in front, I don't think it's applicable here.
* Made the watchlist module private. This is really the definition of private data. There's nothing in the HTTP spec that says the URL for a CC:public request is private and can't be leaked. CC:private provides protection against unknown proxy behaviour.
* In ApiQueryAllmessages: avoid calling $wgLang->getCode() to check if it's necessary to make a new $wgLang when lang= is specified, since this is the only thing that unstubs $wgUser.
* Removed "FIXME: should this check $user instead of $wgUser?" Answer is no.

the rest of MW on principle, but I'm not gonna bother myself." --Roan
