* Wrote two concrete implementations. LBFactory_Simple is for general installations. LBFactory_Multi will replace the runtime configuration used on Wikimedia and allow load-balanced connections to any DB.
* Ported Special:Userrights, CentralAuth and OAI audit to the LBFactory system.
* Added ForeignDBViaLBRepo, a file repository which uses LBFactory.
* Removed $wgLoadBalancer and $wgAlternateMaster
* Improved the query group concept to allow failover and lag control
* Improved getReaderIndex(), it will now try all servers before waiting, instead of waiting after each.
* Removed the $fail parameter to getConnection(), obsolete.
* Removed the useless force() function.
* Abstracted the replication position interface to allow for future non-MySQL support.
* Rearranged Database.php. Added a few debugging features.
* Removed ancient benet-specific hack from waitForSlave.php
* dumpUploads.php options now actually supported
* wfRelativePath() no longer includes spurious ".." when base path is "/"
* wfRelativePath() now returns full path for differing Windows drives
* Put "not yet written" in the title attribute of red links, so that readers unfamiliar with the site might guess what the colour means.
* Fixed minor bugs and refactored code in the vicinity of EditPage::edit().
* Used the new functions in the relevant places throughout the core. Where this was not possible, used wfMsgNoTrans() to avoid double-parsing.
* Calling wfEscapeWikiText() on a title before passing it to a message is unnecessary and causes bugs. The best idea is to let the message do its own escaping. Removed wfEscapeWikiText() from the caller of addedwatchtext, removedwatchtext, deletedtext, protect-text, nosuchusershort and movepage-moved. Updated all message files to use <nowiki>$1</nowiki> where appropriate in these messages.
* Removed unnecessary empty message handling from semiprotectedpagewarning
* Removed nonsense warning about the output of wfMsg() not being safe for inclusion in HTML.
* Changed wfShellExec() to use passthru/ob_get_contents instead of exec(). This avoids corruption of whitespace in the response.
* Added $wgValidateAllHtml feature, to optionally validate HTML on output.
* Fixed missing newline in cascadeprotected in MessagesEn.php
* Belatedly updated addedwatchtext to take account of the new "monobook" skin. No unwatch link in the sidebar anymore.
This avoids PHP warning notices when given not-quite-valid input, such as "http://en.wikipedia.org{{localurl:Talk:Wet_Tropics_of_Queensland/Comments|action=edit}}"
Add $wgStatsMethod to control how (and whether) to update the stats.
Setting to 'cache' (the default) gives the previous behavior of updating in $wgMemc.
Setting to 'udp' sends a line to the UDP profiling host.
Setting to false or 'disabled' or whatever will disable it.
* Fixed #tag behaviour in preprocess()
* Fixed #tag quote stripping regex
* Made MessageCache::getMessage() never transform its result, that is now left up to the caller.
* A few other minor changes
format=raw is an HTML injection machine like action=raw but without any safeguards; it's trivial to create JavaScript exploits which hit at least Internet Explorer.
There's no reason to add a whole new danger point here when you've got machine-readable structure already... please do not add this raw formatter back.
* Removed the hardcoding of the link parameter ($1), let the message control the destination.
* Removed the hardcoded talk page links. They can be easily re-added if desired, though, and added per-wiki.
* Removed the $3 and $4 parameters
* Fixed wfEscapeWikiText() to do "]" as well as "[", so sigs with "]" won't break links
* Updated a parser test case for the escaping change
* accepts 'yes' as well as 'on' and 'true'
* accepts negative and non-1 integers, as well as garbage characters after the number (as C atoi() function for nonzero result)
* JavaScript video player based loosely on Greg Maxwell's player
* Image page text snippet customisation
* Abstraction of transform parameters in the parser. Introduced Linker::makeImageLink2().
* Made canRender(), mustRender() depend on file, not just on handler. Moved width=0, height=0 checking to ImageHandler::canRender(), since audio streams have width=height=0 but should be rendered.
Also:
* Automatic upgrade for oldimage rows on image page view, allows media handler selection based on oi_*_mime
* oi_*_mime unconditionally referenced, REQUIRES SCHEMA UPGRADE
* Don't destroy file info for missing files on upgrade
* Simple, centralised extension message file handling
* Made MessageCache::loadAllMessages non-static, optimised for repeated-call case due to abuse in User.php
* Support for lightweight parser output hooks, with callback whitelist for security
* Moved Linker::formatSize() to Language, to join the new formatTimePeriod() and formatBitrate()
* Introduced MagicWordArray, regex capture trick requires that magic word IDs DO NOT CONTAIN HYPHENS.
* Ported file delete/restore to the filerepo framework. Some user-visible changes in error reporting.
* $wgSaveDeletedFiles has been removed, the feature is now enabled unconditionally. Added a "deleted" directory for the default location, protected by a .htaccess file and the practical obscurity of content hashes.
* Fixed bug 2735: "Preview" shown in title bar for action=submit on special pages
* Removed "restore" links from the deletion log embedded in Special:Undelete
* Added img_sha1/oi_sha1 fields, preserved through upload, delete and restore
* Referenced the new oi_metadata etc. fields to preserve metadata across upload and delete/restore.
