* Correct directionality when viewing diffs
* Correct arrows for Pager
* CSS/JS pages always 'en' (LTR)
* Messages on Special:Allmessages have lang and dir attributes based on the selected language
* Use ParserOptions()->getTargetLanguage() for setting the page language/direction
* Set headings on categories in user language/direction
* Only set language/direction when viewing a page (or editing but only preview and textarea)
For environments post r70783, they will need to rerender pages with __NOEDITSECTION__ or no headings (hopefully those will be simple pages).
There will be no extra parser cache misses for environments pre r70783.
Doing this allows skins to override doEditSectionLinks without poluting the parser cache or fragmenting the parser cache more.
As a side effect it eliminates the primary cause of user language based parser cache fragmentation.
Because this makes most old parser cache entries invalid $wgUseEditSectionTokens is provided so that large installations like Wikipedia can keep their old parser cache entries.
* Removed other usages of $wgUser in Parser stuff, as stated in doc
* Added mechanism to get an User object in Parser, based either on the object given in Paser::preSaveTransform() or the ParserOptions otherwise
use the same parsercache entry for articles without <math> tags.
The cache key format is kept as a fallback so the old cached entries can be reused.
Should boost parsercache hits, but it also makes easier to pollute the parsercache by tag hooks that behave
badly, directly using $wgUser or $wgLang.
Extensions hooking PageRenderingHash now see !edit=0 and the !printable=1 bits.
Fixes bug 24714 - Usage of {{#dateformat: }} in wikis without $wgUseDynamicDates can lead to unexpected results
Builds upon r70498, r70498, r70501, r70517, r70651, r70653, r70765, r70780.
Follow up r48544. Init ParserOptions::mIsPrintable in initialiseFromUser()
Move the "No edit section it's printable" from Parser to Article.
This leaves getIsPrintable() unused. Left there for extensions (none seems to be using it, could be removed).
The "even if the user has them on" comment wasn't accurate. The user preference only controls them via CSS.
Anyway, it would work as expected now if it got moved into ParserOptions. The setEditSection() no longer set it to true.
Remove the quickUserCan( 'edit' ) which is just a hidden way of calling $wgUser from the Parser to be explicitely
done in Article to disable the editsection. This results in quickUserCan being called once instead of twice if $wgUseETag == true;.
* Extended the return interface for tag hooks in a way analogous to the one for parser functions, allowing <nowiki> and <html> to specify that they want to be in the nowiki replacement array instead of the general replacement array.
* Removed ParserOptions::setUseTeX() and related. If <math> is going to be registered in firstCallInit(), then it needs to be stable across multiple parser calls and not change based on parser options. Only one extension caller.
In parserTests.inc:
* Fixed parser test failures due to $wgMathDirectory not being properly set up. The math directory of the host wiki was being used, leading to a parser test failure if it was not writable.
* Fixed message cache hack from r15502. Made parser tests not fail in the case where a tested message is overwritten by the local wiki. All tests now pass on my installation.
* Removed the namespace parameter from Linker::makeExternalLink(), added a generic associative array of attributes instead. Let the Parser decide whether to use rel=nofollow.
* Added an on-wiki external image whitelist. Items in this whitelist are
treated as regular expression fragments to match for when possibly
displaying an external image inline. Controlled by $wgEnableImageWhitelist
