* (bug 16129) Transcluded special pages expose strip markers when they output parsed messages
Also adding some related documentation during my travels around the code
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.
* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable
math conversion after upgrading, obtain the Math extension from SVN or from
http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php:
require_once "$IP/extensions/Math/Math.php";
This is an initial stab, and a few things remain to be cleaned up:
* messages need to be moved from core to extension
* MW_MATH_* constants should be moved to the extension from core
* old back-compat math names interfaces using those constants should be removed from message files
* classic edit toolbar's math button should be added from the extension (or else dropped) -- currently there's not a clean hook, but could do it by JS
* couple of things like the 'armourMath' function on Language & LanguageConverter may want to be redone just as an unconditional, if that's simpler.
Setting $wgUseTeX alone will no longer have any affect. The var's still there for the moment as a few bits still need to be fully moved out from core.
* Made FlaggedRevs specify files by sha1,timestamp to handle renames with no redirects. This makes them handled as well as templates in this regard. (bug 27836)
* Moved BeforeGalleryFindFile hook to proper place (don't trigger for non-NS_FILE titles)
* Removed unused mRevisionId field from ImageGallery
* Removed old hotfix from makeMediaLinkObj(); all the current callers would crash beforehand if the title was null anyway
* Updated hook docs (some prior params were missing)
* Broke some long lines and cleaned up some whitespace
* TODO: track file info in core rather than fr_fileSHA1Keys and ugly, duplicated, queries. This should be easy to do now.
Also fixed a bug in ParserOutput when no option is used; otherwise getUsedOptions() will return false and throw warnings in ParserOptions::optionsHash().
* Fixed several obvious bugs in the $wgCiteCacheReferences helper functions, missed due to inadequate testing.
* Don't save complete Title objects to memcached, they contain cached data with a short lifetime.
* Fixed a doc comment.
* It was not necessary to preserve the $stripState->general->setPair() interface since it wasn't used by any extensions.
* Moved StripState to its own file.
* Refactored serialiseHalfParsedText() and unserialiseHalfParsedText() so that the bulk of the functionality is in the relevant modules, instead of using scary direct access to object member variables. Made it support the new StripState. It seemed like a lot of work to go to to support an "emergency optimisation" feature in Cite. Cite updates will be in a subsequent commit.
* Fixed spelling of serialiseHalfParsedText() and unserialiseHalfParsedText(), there is unavoidable interface breakage anyway, due to cache object versioning.
* Moved transparent tags to their own function, as requested in a fixme comment.
* Added documentation for markerSkipCallback().
* Removed OnlyIncludeReplacer, unused since MW 1.12.
Only used used when amenableparser is passed; the user can now define the page used for {{PAGENAME}} and related stuff instead of being hardcoded to "API"
