* Use Xml::* functions instead of wf* ones
* Call wfDeprecated() in MessageCache::disableTransform(), MessageCache::enableTransform(), MessageCache::setTransform() and MessageCache::getTransform()
* 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
* 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.
* Convert "$dbw =& wfGetDB( DB_MASTER );" --> "$dbw = wfGetDB( DB_MASTER );"
* convert "$skin =& $wgUser->getSkin();" --> "$skin = $wgUser->getSkin();"
For the time being have not changed the function definitions of wfGetDB() or User::getSkin() [i.e. they are still both return-by-ref], so as to ensure the interface does not change for extensions [some of which may still be trying to run on PHP4 environments]. However presumably at some point this can be changed too.
Also includes tiny tweak to newlines in parserTests - will show 1 rather than 2 newlines between the "Reading tests from" strings when in quiet mode.
* removing unused local vars
* removing used global declarations
* adding FIXMEs against extract() calls and lines that seem to be using uninitialized variables
* adding some array() declarations.
* removing some unused global declarations.
* removing or commenting out or adding comments for unused local vars.
* Adding one or two local var declarations.
* Declaring $matches array passed to preg_match() / preg_match_all() as array() before using [not required, just have a slight preference for the explicitness].
* remove one or two pass-by-reference function declarations where the value is not modified.
* Adding some braces to if-else blocks.
* In Parser.php, stripstrate is now an object rather than an array as per r17820, so we no longer need ask for a reference to it (as in "$x =& $this->mStripState;"), and in fact it's probably just simpler to get rid of $x altogether.
* Moving some preg regexes from "" quoting to '' quoting to stop static analyzer whinging about bad escape sequences.
... up to "LinksUpdate.php" in the includes/ directory.
Caches for wikis with table prefixes will be lost on upgrade, caches for wikis without table prefixes will be preserved. Custom cache keys in extensions can be migrated at leisure. Extensions which write to core cache keys should be migrated ASAP, as I have done with Special:Makesysop.
* Because we define the messages 'january-gen', 'february-gen', etc. as the genitive forms of months in Langauge::mMonthGenMsgs, I created them in the English file. This should fix the test of {{CURRENTMONTHNAMEGEN}} in the parser tests (currently seems to output "<january-gen>"), and should fix the wrong output of checkLanguage.php and transstat.php, which think that these messages are obsolete.
* Using the genitive forms of the months in Hebrew
* (bug 6939) Update to Indonesian localisation (id) #31
* Made lines from initialiseMessages() appear as list items during installation
* Moved the bulk of the localisation data from the Language*.php files to the Messages*.php files. Deleted most of the Languages*.php files.
* Introduced "stub global" framework to provide deferred initialisation of core modules.
* Removed placeholder values for $wgTitle and $wgArticle, these variables will now be null during the initialisation process, until they are set by index.php or another entry point.
* Added DBA cache type, for BDB-style caches.
* Removed custom date format functions, replacing them with a format string in the style of PHP's date(). Used string identifiers instead of integer identifiers, in both the language files and user preferences. Migration should be transparent in most cases.
* Simplified the initialisation API for LoadBalancer objects.
* Removed the broken altencoding feature.
* Moved default user options and toggles from Language to User. Language objects are still able to define default preference overrides and extra user toggles, via a slightly different interface.
* Don't include the date option in the parser cache rendering hash unless $wgUseDynamicDates is enabled.
* Merged LanguageUtf8 with Language. Removed LanguageUtf8.php.
* Removed inclusion of language files from the bottom of Language.php. This is now consistently done from Language::factory().
* Add the name of the executing maintenance script to the debug log. Start the profiler during maintenance scripts.
* Added "serialized" directory, for storing precompiled data in serialized form.
* Made autoloader work for unserialize()
* Made XmlFunctions.php and HttpFunctions.php autoloadable modules, via Http:: and Xml::
* Made Image class autoloadable, global functions moved to ImageFunctions.php where they can be loaded on every invocation.
* Removed some unnecessary require_once() calls
* Deferred $wgValidSkinNames initialisation
* Fixed a couple of silly construct/initialise splits. My idea from C++ experience, bad practice in PHP.
* Deferred skin initialisation in ParserOptions
* Removed $wgMwRedir during an attempt to make MagicWord autoloadable. Didn't complete that, but removing the global is still the right direction.
* remove require_once() throughout whole code, yet left in few places
* move global functions in HttpUtils, ProxyTools, Credits to class methods
* php5 only: __autoload() now used, combined with class->file map and require()
* move initialization of $wgValidSkinNames to Skin::getSkinNames()
* few more changes that will surely break stuff.
