Here is a short overview of changes and associated default configuration variables (most everything is off by default) also see ~soon to be updated~: http://www.mediawiki.org/wiki/Media_Projects_Overview
= Upload Improvements =
==Upload API ==
* Based on the early work of Bryan Tong and others it adds the upload option to the api.
* We rewrite Special:Upload page to include use the new refactoring
* Added in token checks in both the SpecialUpload.php page so avoids DOS / xss copy-by-url JavaScript based cross site POST file submissions
== Copy by URL==
$wgAllowCopyUploads = false;
* http class rewrite includes a new http background download see: includes/HttpFunctions.php
* spins off a php process that calls: maintenance/http_session_download.php
* pushes updates to the session and gives the user a progress bar on http copy uploads from other server progress (using js2 upload interface) (if not using the js2 upload interface it does the request in-place but the download is limited to the php ini timeout time)
== Firefogg ==
* Firefogg enables resumable upload by chunks
* progress indicators and conditional invokation (js2 system)
* and of-course client side transcoding.
= Script Server =
$wgEnableScriptLoader = false;
* off by default if $wgEnableScriptLoader is turned on script files are grouped, gziped, cached etc.
for more info see: http://www.mediawiki.org/wiki/Extension:ScriptLoader
* Includes some early skin js include fixes (skin/script system still lots of love)
* Includes a "javascript class autoloader" this is packaged into mwEmbed so that the mwEmbed library can work in stand alone mode (while retaining localization and script serving) (one such application is the make page for firefogg.org : http://www.firefogg.org/make/index.html )
* The file that contains the autojavascript loading classes is: js2/php/jsAutoloadLocalClasses.php
* One can use this auto class loading dependency system with extensions and add-ons but I need to better document that.
= js2 system / mwEmbed=
$wgEnableJS2system = false
* includes initial rewrite towards more jquery based javascript code
* especially for the Special:Upload page.
* Also the edit page include support for the "add-media-wizard"
* includes dependency loader for javascript that optionally takes advantage of the script-loader
* remote embedding of javascript interfaces (like embedding video, or commons media searching)
* $wgDebugJavaScript = false; .. .this variable lets you always get "always fresh javascript". When used with the script-loader it does not minify the script-loader output.
= mwEmbed =
* Will commit a separate patch to oggHandler that conditionally outputs <video tag> to use the new javascript video player.
** mv_embed player includes: play-head, volume control, remote embedding, oggz-chop support across plugins.
* add-media-wizard adds easy inserts of media to pages (with import)
== jQuery==
* we include a base install of jQuery, jQuery ui and some plugins.
* all the javascript classes are in the scriptloader so its easy to load any set of jquery ui components that you may need using the script-server. You get a callback so you can then execute js with dependencies loaded.
== other stuff ==
there is a bit more code in js2 that pertains to sequence editing, timed text display and basic image editing. We include a base import of pixastic-lib & pixastic-editor... will work with the pixastic developer to try and ensure upstream compatibility on our usage of the library for in-browser photo and sequence manipulation.
* New WantedQueryPage class for all of these Wanted*s, moved some identical methods to it
* Removed sortDescending() because it was already defined as returning true @ QueryPage, no need to duplicate
* forced intval() for the "value" field in QueryPage::recache() since some pages select page_title for it, which is incompatible with "integer"
* changed Special:Unusedimages' query to return the UNIX timestamp rather than raw img_timestamp for the "value" field, the latter has the TS_POSTGRES format on PostgreSQL and is also incompatible with "integer", code taken from Special:Ancientpages
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.
* Used the new functions in the relevant places throughout the core. Where this was not possible, used wfMsgNoTrans() to avoid double-parsing.
* Calling wfEscapeWikiText() on a title before passing it to a message is unnecessary and causes bugs. The best idea is to let the message do its own escaping. Removed wfEscapeWikiText() from the caller of addedwatchtext, removedwatchtext, deletedtext, protect-text, nosuchusershort and movepage-moved. Updated all message files to use <nowiki>$1</nowiki> where appropriate in these messages.
* Removed unnecessary empty message handling from semiprotectedpagewarning
* Removed nonsense warning about the output of wfMsg() not being safe for inclusion in HTML.
* Changed wfShellExec() to use passthru/ob_get_contents instead of exec(). This avoids corruption of whitespace in the response.
* Added $wgValidateAllHtml feature, to optionally validate HTML on output.
* Fixed missing newline in cascadeprotected in MessagesEn.php
* Belatedly updated addedwatchtext to take account of the new "monobook" skin. No unwatch link in the sidebar anymore.
* 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.
