* Fixed parse() arguments in getRevIncludes()
* Changed clearTagHook() to avoid preprocessed-xml cache corruption
* Check current version cache in getRevIncludes()
* Encapsulate index.php in wfIndexMain() (similar to r77873)
* Kill $wgArticle check in Exception, not necessary anymore
* Kill $wgArticle in Setup, also not necessary
* Add angry note about $wgArticle to rebuildFileCache.
* Remove note about $wgArticle in Parser since it's dying anyway
* Parser now only adds the redirect source to imagelinks, like it does in pagelinks
* ImagePage now shows the file redirects in-line with the normal "The following pages link to this file:"
** Added message linkstoimage-redirect
** Removed the separate file redirects section and removed associated message redirectstofile
** ImagePage::imageLinks will first fetch image links to the file, determine which are redirects, and if there are fewer links than the limit, fetch the redirect target links.
Added notes about the 'extended' return values from some of the hooks, which seems to be undocumented but is vaguely similar to what is documented for parser function callbacks. It doesn't look like a very safe interface, and could stomp on internal variables if one isn't careful. Needs to be better defined and doc'd.
setTransparentTagHook() seems to have been largely undocumented and is only used by the 'geoserver' extension currently. Is this considered obsolete? Should it be simply replaced by use of the frame & recursiveTagParse goodies, or is it still needed for something?
* (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* (bug 14202) $wgUseTeX has been superseded by the Math extension.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.
