* Add @addtogroup tags to various classes, to try and group conceptually-related classes together.
* Add brief descriptions to various Special pages, thanks to Phil Boswell.
* Moving some docs to be right above the classes they represent, so that they are picked up.
* 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.
* 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.
* This will allow the backend text storage to use different id numbers
* Revisions noting metadata changes can be added to history without duplicating text
(implemented for page move)
This changes the revision table schema and requires running update.php
or maintenance/archives/patch-rev_text_id.sql on existing test wikis.
PostgreSQL table defs are still not in sync, so not updated.
* Removed 'fuzzy title search', it's not been maintained and generally produces unexpected and unwanted results
* Separated search guts (in SearchEngine) from display/control (in SpecialSearch)
* Extracted MySQL3 and MySQL4 variants to subclasses
* Added PHPUnit tests for MySQL3 and MySQL4 search engines, which try to use temporary tables to fiddle in (if configured)
* comments n stuff
