* Removed some backtracking regexes with an O(N^2) worst case, replaced with StringUtils::delimiterReplace(). There is a beneficial functional difference: /*/ is no longer considered to be a complete CSS comment.
* Changed the parser strip state from an array to an object. This should hopefully avoid the PHP bugs with array references. StripState uses the new ReplacementArray to do the replacements, thereby supporting FSS.
* Removed DatabaseFunctions.php from the default startup sequence. Moved wfGetDB() to GlobalFunctions.php.
* Introduced the SiteStats class, with a collection of cached site stats accessor functions.
* Removed all global functions from Parser.php, they don't belong there.
* Made LanguageConverter use the new ReplacementArray class instead of managing its own FSS objects.
Purging was using getViewUrl(), which is a generated thumbnail for SVG and other render-only formats.
Switched to using getUrl(), which returns the file itself. The thumb will be separately covered as is.
Somebody changed the parameters and return value of Image->thumbUrl()
and didn't update all uses. Silly of them!
Also add a paranoia check on urls in the list in SquidUpdate
And don't redefine the socket options constants when called a second time
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.
* Deleted DatabaseMysql.php, no longer necessary, database classes are autoloaded.
* Moved wfGetMimeMagic() to MimeMagic::singleton()
* Fixed a couple of __CLASS__.'::'.__FUNCTION__ things.
* 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.
You can now feed both local relative URLs and fully-qualified URLs to the
squid purge functions; local URLs will have $wgInternalServer prepended
if needed. This avoids the broken URLs produced by other functions prepending
it when it wasn't always needed.
