Revision: 114429
Author:   reedy
Date:     2012-03-22 19:43:00 +0000 (Thu, 22 Mar 2012)
Log Message:
-----------
* (bug 34212) ApiBlock/ApiUnblock allow action to take place without a token 
parameter present

* (bug 35317) CSRF in Special:Upload
Revert r56793, which removed the CSRF check for Special:Upload for normal file
uploads. Cross-site posting of file uploads without user interaction has been
possible since at least as early as Chrome 8 (late 2010) and Firefox 6 (mid
2011). 

Commonist has used api.php since version 0.4.0 (April 2010), and the API
already requires an edit token, so Commonist 0.4.0+ is not affected by this
change.

* (bug 34907) Fix for CSRF vulnerability due to mw.user.tokens. Patch by Roan
Kattouw and Tim Starling.
* Filter out private modules early in ResourceLoader::makeResponse() and just
pretend they weren't specified. This means these modules cannot be loaded
through load.php . This filtering must not happen in makeModuleResponse(),
because that would break inlining.
* Force inlining of private modules in OutputPage::makeResourceLoaderLink(),
disregarding $wgResourceLoaderInlinePrivateModules
* Remove $wgResourceLoaderInlinePrivateModules
* Remove special treatment of private modules ($private) in
ResourceLoader::makeResponse() and sendResponseHeaders(), because we're not
allowing private modules to be loaded through here any more
* Remove identity checks in ResourceLoaderUserOptionsModule and
ResourceLoaderUserCSSPrefsModule, they didn't make a lot of sense before but
they're certainly useless now.
* Factored out error comment construction in ResourceLoader.php and stripped
comment terminations from exception messages. I didn't find an XSS
vulnerability but it looked scary.

* (bug 35315) XSS in CharInsert, forged strip markers
