Doxygen documentation update:
* Changed alls @addtogroup to @ingroup. @addtogroup adds the comment to the group description, but doesn't add the file, class, function, ... to the group like @ingroup does. See for example http://svn.wikimedia.org/doc/group__SpecialPage.html where it's impossible to see related files, classes, ... that should belong to that group.
* Added @file to file description, it seems that it should be explicitely decalred for file descriptions, otherwise doxygen will think that the comment document the first class, variabled, function, ... that is in that file.
* Removed some empty comments
* Removed some ?>
Added following groups:
* ExternalStorage
* JobQueue
* MaintenanceLanguage
One more thing: there are still a lot of warnings when generating the doc.
* Verified Preprocessor_Hash against Preprocessor_DOM with a differential fuzz test.
* Improved the utility of Parser_DiffTest by synchronising strip markers and allowing for loose object comparison.
* Abstracted PPDStack to make it usable in Preprocessor_Hash.
* Stabilise timestamps generated by the parser to avoid diff test false positives
* Fixed msgnw bug. Use RECOVER_ORIG.
* Fixed editintro bug. Cloning the parser in MessageCache has some side-effects that need to be corrected.
* Fixed typo in Parser_DiffTest.php
* General improvements to preprocessorFuzzTest.php
* Fixed breakage of XML output feature in Special:ExpandTemplates
* Made it possible to configure the parser class being used, via $wgParserConf.
* Moved defines from the top of Parser.php to either class constants or Defines.php
* Added Parser_DiffTest, a differential parser class for regression testing
* Added Parser_OldPP, a parser class which operates like the parser before this commit. I made one breaking change: a bugfix to avoid losing whitespace when adding MWTEMPLATESECTION markers.
* Made internal tidy work with PHP 5
* Added the ability to supply a hook for template fetching via ParserOptions. This is handy for testing.
* Updated parserTests.txt to account for the various breaking changes I made. Removed a few parser tests that no longer test for anything useful.
