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	In use? Alternatives?
CirrusSearch	Yes	Extends the core search for MediaWiki to be able to use Elasticsearch	Continuous	Yes	Yes	Yes
Cite	Bundled in the official tarball release of MediaWiki (aka 'the download').	Provides <references /> and <ref></ref> tags	Continuous	Yes	Yes	UNUSED
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	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. So, for example, a search box on a page or category with many subpages; preconfigured to "Search this space".	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.
ParserFunctions	Bundled	Enhances the wikitext parser with helpful functions, mostly related to logic and string-handling.	Continuous maintenance	Yes	Yes	Yes
PdfHandler	Bundled	The PdfHandler extension shows uploaded pdf files in a multipage preview layout. With the Proofread Page extension, pdfs can be displayed side-by-side with text. This allows users to transcribe books and other documents.	Continuous	Disabled	Yes	UNUSED
PipeEscape	Bundled	The Pipe Escape extension allows for pipe characters in parser function arguments (and template argument calls) avoid being interpreted as an argument delimiter. This is primarily for the purpose of using wiki tables (or parts thereof) inside parser function calls or templates.	Old but stable	Yes	Yes	Included via DcsSetup
Poem	Bundled	The Poem extension allows easy formatting of poems and similar material within Wikitext. Once the extension is enabled, you can put any block of text within <poem></poem> tags	Continuous updates	No	Yes	UNUSED
Renameuser	Bundled	The Renameuser extension provides a special page which allows authorized users to rename user accounts. This will cause page histories, etc. to be updated. If you want to rename an account "into" another, already existing one, you need the User Merge and Delete extension.	Continuous updates	No	Yes	UNUSED
SimpleMathJax	No, WMF uses the Math extension	The SimpleMathJax extension enables MathJax, a Javascript library, for typesetting TeX formula in MediaWiki inside math environments. This extension will load resources from cdnjs.cloudflare.com on all wiki pages that have math or chem tags.	Regular maintenance	Yes	Yes	included by DcsSetup.php
SpamBlacklist	Bundled	The SpamBlacklist extension prevents edits that contain URLs whose domains match regular expression patterns defined in specified files or wiki pages and registration by users using specified email addresses. When someone tries to save a page, SpamBlacklist checks the text against a (potentially very large) list of illegal host names. If there is a match, the extension displays an error message to the user and refuses to save the page.	Continuous updates	No	No	UNUSED
SyntaxHighlight_GeSHi (now known simply as SyntaxHighlight)	Bundled	Provides rich formatting of source code using the <syntaxhighlight> tag. It is powered by the Pygments library and supports hundreds of different programming languages and file formats.	continuous updates	Yes	Yes	UNUSED
TitleBlacklist	Bundled	Combat spam and vandalism. Allows wiki administrators to block the creation, movement and upload of pages, the title of which matches one or more regular expressions, as well as blocking creation of accounts with matching usernames. (Prevent account creation by "he who shall not be named" or prevent pages like "Sh*t".	1.5.0 (2014-03-29) some oversight by WMF	No	No	UNUSED
WikiEditor	Bundled	The WikiEditor extension provides an improved interface for editing wikitext. It is the wikitext editing interface that Wikipedia started using in 2010 for desktop users, and so it is sometimes called the "2010 wikitext editor".	0.5.1 (2016-04-15) some oversight by WMF	Yes	Yes	Yes

Custom DCS Extensions

Extension	Purpose	Last release	Example usage + 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	https://clienttest.dm.dcstemporary.com/ARCA14:1.5_Time_References
DcsBaskets	This extension allows the utilization column of the Baskets tables to be edited directly using AJAX and saving values into 'basket' tables rather than in the traditional wiki-text revision tables.	1.4.3, 2018-05-25	"Baskets" can be found in the hierarchy list of the leftnav under the 'Compliance' folder. The page name, by convention, is 'Baskets' e.g. https://clienttest.dm.dcstemporary.com/Baskets This is really neat, and very advanced. However, now that Visual Editor is available, I'd suspect that the user experience of editing large tables in Visual Editor would be much better. Replace Baskets with Visual Editor
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.	recent	pervasive
DcsComplianceChecklist	Provides a dropdown list of loans and responsibility terms by which the table can be filtered on the Checklist page (by convention). The parser function creates the page contents and form controls.	recent (2017 - 2018)	e.g. https://clienttest.dm.dcstemporary.com/Checklist
DcsComplianceChecklist2	purpose?	release?	only used in the checktest subdomain, or when `wgLocalTesting`; intention is to use a timestamp condition
DcsEmailLink	Allows you to send a link to a page in the wiki. Activated by the "Email Link" item in the primary navigation across the top of the page. Similar to the "Email Page" extension by Aran, which is also used.	11 months ago	visit any page
DcsExportTerms	Allows terms to be downloaded in Comma Separated Value (CSV) format. CSV is easily imported to a spreadsheet.	recent	Visit https://clienttest.dm.dcstemporary.com/Category:Terms and you will see a "Export Terms" action in the primary navigation across the top of the page.
DcsFindTitle	helps to find a title regardless of case-sensitivity of the system.	recent	integrates with the API, however I'm unsure where it's visible/usable to the user. I believe it's used from the Ruby side to create links that will match a wiki page even if there is a case mismatch. If you wish to navigate to https://clienttest.dm.dcstemporary.com/ARCA14:TOC but request https://clienttest.dm.dcstemporary.com/arca14:toc instead, you'll get a 404 Not Found error. If you request https://clienttest.dm.dcstemporary.com/arca14:toc?action=findtitle then you will be redirected to the proper article.
DcsGroupAdmin	Leverages the DcsBlockPageAccess hook to allow/disallow access to files and namespaces.	recent	https://clienttest.dm.dcstemporary.com/Special:DcsGroupAdmin/equality
DcsJobAdmin	See Background info on Background jobs. Creates a Special Page Special:DcsJobAdmin where you can start a new job; or view current and historical jobs. Each job type loads it's own form into the Admin page. The job runner extends the Maintenance class, and loops over running jobs to provide some progress reporting. It saves the most recent 10 jobs to a 'history' list. There are functions in the code for: Return a list of the currently running jobs sorted by start time. Add a job to the 'history' list of jobs executed (list is limited to 10 items). Get a 'history' list of the last 10 jobs Get job data (both current and history) shell_exec() to the process table to find DcsJobRunner. Return the currently running jobs by Process ID (PID) register the PHP code classes for each job type: Change Namespace EditTest Import ImportXML Links PhpTest ReplaceText UpgradeAttachments Each (or almost all?) PHP file is backed by a perl file which was the basis for the PHP development. Everything is written twice because it all started back when the best framework for handling MediaWiki jobs was a perl bot framework. Things have changed significantly over the recent past for MediaWiki's job queue. According to the documentation, it allows you to manage jobs. But, I'm wondering how much this is actually used? The job queue should be run automatically by cron, and the administrative user shouldn't have to worry about it really. If there is a usage pattern where job execution is time sensitive, there is a use for an Admin function; but I'm curious about the usage patterns that create large or numerous jobs. Otherwise, set wgJobRunRate to zero, and put it into cron `0 0 * * * root /usr/bin/php /var/www/example.com/www/w/maintenance/runJobs.php > /var/log/runJobs.log 2>&1`	2018-05-25	yes
DcsLoanPages	creates "backlinks" which are links to content that contain a particular keyword or phrase found in a loan document. It also creates the "< Prev" and "Next >" navigation links (called 'breadcrumbs' in the code, but actually these are 'pager' links not breadcrumbs).	recent	If you go to a page like https://clienttest.dm.dcstemporary.com/ARCA14:Agreement You will see a large section of content called 'Index to ARCA14 pages containing "Agreement"" So, in other words, it's a list of links to pages of the ARCA14 loan that have the word "Agreement" in them. These links are created by the extension.
DcsNamespaces	Manages the segregation of loan documents into their own separate namespaces. Also provides some functionality around moving/deleting/renaming namespaces via the https://clienttest.dm.dcstemporary.com/Special:DcsNamespaces special page.	recent	e.g. https://clienttest.dm.dcstemporary.com/Special:DcsNamespaces
DcsNuke	purpose?	release?	yes. REPLACE with standard Nuke extension
DcsSearch	Extends the Elasticsearch backend with additional business logic, and new features and UX (saving search "favorites" and indexing link paths traversed in connection with a search query). See https://github.com/debtcompliance/mediawiki/wiki/Search-&-sorting	a year ago	e.g. See the "heart" symbol next to the search box which implements the "favorites" feature.
DcsSection	Allows for loan documents to be imported into the wiki as multiple articles. Creates a 'section reference' capability.	in progress (v2)
DcsSection2	purpose?	release?	NO - at least not on the development machine which is a clone of production.
DcsSingleSignOn	Create a master/slave relationship with the Ruby on Rails application as the authentication and group mangement source; with the MediaWiki application synchronizing user information into it's local database.	2017 major update	For testing, you can access /wiki/extensions/dcs/DcsSingleSignOn/testLogin.php
DcsSkin	Custom 'style' to match DCS website / frontend	recent	Yes
DcsTitle	Extends the regular MediaWiki title object class. Creates a custom cache of the TOC.	recent	yes
DcsUploadedFiles	Creates a special page listing all the files uploaded to loan documents orderd by loan namepsace then by article	a year ago	https://clienttest.dm.dcstemporary.com/Special:DcsUploadedFiles
DcsUserDisable	Adds 'enable/disable' links to the User list	a year ago	https://clienttest.dm.dcstemporary.com/Special:ListUsers Why not use the Special:Block functionality built into core?I believe it's every bit as accessible through the API and thus could be used from QAR.
DcsWatchComments	Adds subscription to talk pages.	release?	When I view my normal MediaWiki 'WatchList', I don't see any loan talk pages added. I only see my user page.
