Extension inventory

This page serves to inventory and assess the mix of extensions that are in use for the DCS wiki. Code for "regular" extensions are hosted on Gerrit at the WMF (which is also mirrored to GitHub) with documentation at https://www.mediawiki.org/wiki. Code for the DCS extensions is in the private Debt Compliance GitHub repo; and the Organic Design extensions are in the 'MediaWiki' tree of the Organic Design GitHub repo.

"Regular" Extensions

Extension	Used by WMF projects?	What does it do?	Maintenance / Last release	Used by Meza	Used by QualityBox	Alternative Extension
CirrusSearch	YES	Extends the core search for MediaWiki to be able to use Elasticsearch	Continuous	Yes	Yes
Cite	Bundled	Provides <references /> and <ref></ref> tags	Continuous	Yes	Yes
CiteThisPage	Bundled	Provides Cite This Page Special Page.	Continuous	No	Yes	UNUSED
ConfirmEdit	Bundled	Adds CAPTCHAs for page saves and other user actions to protect against spam and password-guessing	Continuous	No	Yes	UNUSED
Elastica	YES	Base Elasticsearch functionality by providing the Elastica library; required by CirrusSearch.	Continuous	Yes	Yes
Gadgets	Bundled	Provides a way for users to pick JavaScript or CSS based "gadgets" that other wiki users provide.	Continuous	No	Yes	UNUSED
ImageMap	Bundled	The ImageMap extension allows clickable image maps.	Continuous	Yes	Yes	UNUSED
InputBox	Bundled	The InputBox extension adds already created HTML forms to wiki pages.	Continuous	Yes	Yes	UNUSED
Interwiki	Bundled	The Interwiki extension adds the "Special:Interwiki" page to MediaWiki, to view and edit the interwiki table, and a log of any actions made with it.	Continuous	Yes	Yes	UNUSED
LocalisationUpdate	Bundled	allows to update the localizations for MediaWiki messages at any time, without needing to upgrade the MediaWiki software.	Continuous	No	No	UNUSED
Nuke	Bundled	The Nuke extension makes it possible for sysops to mass delete pages.	Continuous	No	Yes	For whatever reason, the DCSNuke extension intercepts page requests for the Nuke special page. DCSNuke has no added functionality. The DCSNuke code is roughly equivalent to the REL1_20 release of Nuke; and the current Nuke extension offers more functionality. I thought that potentially the reason to use a cloned extension was to totally customize the interface language strings, but that's not the case. Remove DCSNuke.

Custom DCS Extensions

Extension	Purpose	Last release	Confirm used? + notes
DcsAmmendments	Adds ammendments section to DCS loan pages. Sysop (only) can add/delete/edit/re-order (up/down) the ammendments; UX implemented in JavaScript. Extends the API with the same functions. Adds new log type: amendments; and logs all actions.	Jan 2018 - new sort functionality ready for testing	yes
DcsBaskets	purpose?	release?	yes
DcsCommon	https://github.com/debtcompliance/mediawiki/wiki/Extensions#dcscommon	Cookie handling was added on June 14, 2017. The code (the cookie.js part) is from a project called js-cookie. So, we could update that code. Or, we could replace it with internal functions so we don't rely on 3rd party code. See the API documentation for mw.cookie (Does not use the $wgCookieSecure configuration variable since 'detect' could not work with ResourceLoaderStartUpModule; as module cache is not fragmented by protocol.) The mw.cookie (JavaScript) code is syntactically and functionally similar to the server-side cookie API (`WebRequest#getCookie` and `WebResponse#setcookie`). https://www.mediawiki.org/wiki/Manual:Hooks/UserSetCookies is deprecated as of REL1_27, and session-handling extensions should be subclassing CookieSessionProvider. $wgSessionProviders The class creates methods for outputting messages, notices, dates, getting raw content. It loads some javascript (through resource loader). That javascript could more easily be maintained as MediaWiki:Common.js? although there may be load order issues. The JS defines like-named methods with varying features. E.g. Check if the passed page title string is in a loan namespace, returns boolean. Note that this function only checks if the namespace is in the list of all loan namespaces, it doesn't do any checks for whether the namespace is in use, or whether the title is in a DCS_TOC article like the DcsCommon::isLoanPage PHP function. The series of extensions create DcsInit() (in DcsEmailLink), DcsBlockPageAccess(), and DcsReady() hook functions. DcsReady() implementations are different across different classes from Basket to DcsSingleSignOn.	The 'common' extension creates a singleton instance of the DcsCommon class that does a bunch of things according to notes in the wiki. The permissions shouldn't really be hidden away in the class code. They should simply be in LocalSettings.php. onUserGetRights() is a big function. The 'self:cache' is mostly called in connection with 'isLocal'. Any true caching should just be offloaded to APC and memcache. Although there is no 'dcs' table in the database on dcsTemporary, the setData() method is used throughout the codebase so should update wiki about where this data is stored.
