* Removed permissions check from WikiPage::doUpdateRestrictions() and left it for callers, resolves the todo from documentation
* Inverted $expiry and $reason parameter between WikiPage::doUpdateRestrictions() and WikiPage::updateRestrictions() for more consistency; WikiPage::doUpdateRestrictions() also requires all parameters to be passed
* WikiPage::doUpdateRestrictions() returns a Status object instead of bool for the older one; only possible error at the moment is a read-only database
* Updated core calls to these functions
* Made maintenance scripts using it simply protect all actions returned by Title::getRestrictionTypes() instead of hardcoded 'edit' and 'move'
* This also means that protect.php can be used to protect a non-existing page for creation
* WikiPage::getParserOutput() requires a ParserOptions object (and optionally the revision ID) instead of an User object, removes an hidden dependency on $wgLang. For this reason, WikiPage::isParserCacheUsed() now also uses a ParserOptions object instead of an User object (doesn't change anything in the code except the variable name and it's not called in extensions)
* Moved PoolWorkArticleView to WikiPage.php and added an entry in the AutoLoader and moved output-related stuff directly in Article::view() so that in can be shared with WikiPage::getParserOutput() (removes code duplication, etc.)
* Added the revision ID to the PoolCounter key so that it knows which revision is being parsed and doesn't wait for another parse operation with same options but different revisions
* Removed Article::doViewParse(), Article::tryDirtyCache() and Article::getOutputFromWikitext() since they are now integrated in PoolWorkArticleView and Article::view() and there are no callers in extensions. This also fixes a bug since Article::doViewParse() will get another ParserOptions instance with special options set in Article::view() not be repercuted.
* Updated DifferenceEngine to use the new system
* Updated docs/memcached.txt to correct method names
* Moved the page check if oldid was given from Article::fetchContent() to Article::getOldidIDFromRequest() so that it's done directly when executing Article::view(); this should not happen though for normal view requests since oldid and related are checked in MediaWiki::parseTitle()
* Removed $oldid parameter from Article::fetchContent() and always use the oldid parameter passed either in the constructor or the request; also changed call from Article::loadContent() to Article::fromContent() since the former is now only a redirect to the latter
* Moved the 'read' permission check to the beginning of Article::view() since the Title is now correct directly after calling Article::getOldID()
* Merged the two calls to the parser cache and make WikiPage::isParserCacheUsed() also return true when the latest revision id is given. Article::setOldSubtitle() is still called when the oldid is passed to display the "You are view the current revision of this article".
* Also moved the non-existing page check a bit up to avoid running a good part of useless code when the page doesn't exist
* Merged two calls to Title::quickUserCan( 'edit' ) to set edit sections to false
* Make OutputPage::setSubtitle(), OutputPage::addSubtitle() and OutputPage::appendSubtitle() accept a Message object in addition to a string
* Added new method OutputPage::addSubtitle() to replace appendSubtitle() and marked it as deprecated
* Clear the subtitles when showing an error page
* Always show the subtitle from Article::viewRedirect() when showing a page; left the parameter for use in EditPage
* Make Article::setOldSubtitle() add two subtitles and has to set "display:inline;" for the three possible divs to avoid too many spacing
* Removed the six different backlink subtitles and added one new message 'backlinksubtitle' to replace them and added OutputPage::addBacklinkSubtitle() to factorise common code
* Changed EditPage's view source to show "View source for <Page>" with the same backlink in subtitle for consistency with other back links and page titles
* (bug 26020) Setting $wgEmailConfirmToEdit to true no longer removes diffs from recent changes feeds
* Added second parameter to Title::userCan() and Title::quickUserCan() to allow callers to pass the User object to use for checks; this changes Title::userCan()'s second parameter from "do expensive queries" flag to User, but all callers should have been updated in r102183
* Updated callers that might throw a PermissionsError to use getUserPermissionsErrors() instead and pass the error array to the exception
* Refactored duplicate code in missingPermissionError()
* Moved Title::isNamespaceProtected() a bit upper and Title::userCanRead() near Title::userCan() to have related functions in the same location
* Some minor refactoring in permission-related functions in Title
* This replaces OuputPage::loginToUse() functionnality, made it simply throw a PermissionsEror exception and updated all calls in core
* Same for the check in SpecialUpload::execute(), EditPage::userNotLoggedInPage() and EditPage::noCreatePermission()
* Throw the same exception in EditPage::attemptSave() whether the user is logged in or not and let OuputPage::showPermissionsErrorPage() decide which message to display
* Replaced call to deprecated OutputPage::blockedPage() in SpecialUpload
* Displayed messages are the same as now, except the title is always "loginreqtitle"
* 'nocreatetitle' and 'uploadnologin' messages are still used by extensions, so I kept them, but the message 'whitelistedittitle' is not used anymore and has been removed
* Use the new 'cannotdelete-title' message for the title on error instead of "internal error"
* Don't use OutputPage::showFatalError() but add the content by "normal" methods (related to the item above)
* Don't use the $DeleteReason and $DeleteReasonList member variables in Article and FileDeleteForm but local variables since they are not used anywhere else
* Moved down some variable definitions near where they are used so that they are only set when they will actually be used
* Same for the setPageTitle() call with 'delete-confirm' message in Article::delete() that is now in Article::confirmDelete()
* Added missing "true" as fourth parameter of WikiPage::doDeleteArticle() call that was missing
* Factorised getTitle() and getUser() calls
* Salt token with array( 'delete', 'page title' )
* PermissionsError now calls OutputPage::showPermissionsErrorPage() to display the error (this is needed to make the item above work correctly)
* Removed the override of the HTML title in OutputPage::showPermissionsErrorPage() so that it shows "Permission errors - Sitename" instead of simply "Permission errors" for consistency with the other things
* Pass the error array returned by Title::getUserPermissionsErrors() to PermissionsError where available
* Converted direct calls to OutputPage::showPermissionsErrorPage() to throw an PermissionsError error instead
* Added 'action-rollback' message that will be displayed when accessing action=rollback without sufficient rights
* Changed getRestriction() in subclasses of Action to return null when they previously returned 'read' so that user rights can be check with Title::getUserPermissionsErrors()
* Reordered checks to do first user rights, then block (if needed) and finally read only (also if needed) so that users don't think the error is temporary when they both don't have right and the database is locked
* Removed OutputPage::setPageTitleMsg() and OutputPage::setHTMLTitleMsg() and make OutputPage::setPageTitle() and OutputPage::setHTMLTitle() accept a Message object
* Updated core calls (including some that I missed last time because of non-matching case)
* Added Message::setContext() and use it in RequestContext so that I don't need to duplicate the call in OutputPage
* Yes, I'm calling $this->msg() on places and then setting the context one more time in OutputPage::setPageTitle() or OutputPage::setHTMLTitle(), but at least I won't be confused about which objects $
* Rewrote class and split into three classes: a base class, and html cache and a more generic cache to be used later.
* The new classes now use RequestContext.
* Renamed fetchPageText() -> fetchText().
* Split out new saveText() function from saveToFileCache().
* Various other cleanups and fixes.
Also fixed backwards setting of $wgDisableCounters in rebuildFileCache.php.
* Do additional validation and is_array() check in LanguageConverter
* Make redirects be in content language again (remove from Title->getPageLanguage())
* Pass title object from ParserCache to ParserOptions->optionsHash
* Made variant tabs hidden on special pages (has no or sometimes wrong/inconsistent effect there; plus it's mainly in the user language)
* Made redirects be in content language again (remove from Title->getPageLanguage())
* Moved generateReason() to WikiPage. This fixes the PureWikiDeletion ext too.
* Make Checkpoint ext call getRawText() as doEdit() does. Aalso, WikiPage doesn't have fetchContent().
* Call getAutosummary() statically in doEdit().
* Fixed outdated code comment.
* Fixed title used in unit test.
