define new namespaces in extensions.
Without the hook the list could be initialised too early and some namespaces
would be left undefined. Was causing problems at translatewiki.net.
Now those two together define the set of namespaces used in the wiki.
$wgExtraNamespaces is for user configuration and overrides, while
$wgCanonicalNamespaceNames is for extension adding their own namespaces.
No code should access those two directly for reading. Instead they should use
MWNamespace::getCanonicalNamespaces.
Also fixed indentation with spaces to tabs in Language.php
This is a global search and replace of NS_IMAGE and NS_IMAGE_TALK with NS_FILE and NS_FILE_TALK respectively in all core files, excluding those already updated in step 1 (r44004).
* Parser tests updated. 14 failing parser tests before the change, added one, and the same 14 failing parser tests are remaining
* added namespace aliases for Image and Image_talk for backward compatibility purposes
* Add MWNamespace::hasSubpages() and use that instead of $wgNamespacesWithSubpages everywhere
* Put early returns first, and don't else { } the rest of the code
* @ingrouo -> @ingroup (whoops!)
* Fix doxygen warnings
* Remove duplicate definition of $wgMetaNamespaceTalk in DefaultSettings.php, thanks to VasilievVV for pointing this out
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.
Currently in experimental mode, use $wgAllowImageMoving to enable it.
Known issues:
* Doesn't work with rev_deleted
* May also have some security and caching issues.
* PHP 5.3 compatibility fix for wfRunHooks() called with no parameters
An autoloaded 'Namespace' class alias is retained for compatibility with
extensions which haven't updated to the new class name... however they too
will break on PHP 5.3. Yay!
