The ExtensionDistributor extension generates .tar.gz snapshots of extensions in the git repository and distributes them. It is intended for use on www.mediawiki.org. See Special:ExtensionDistributor to see how it works.

Installation edit

  • Download and move the extracted ExtensionDistributor folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/ExtensionDistributor
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'ExtensionDistributor' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration settings:

 * Configuration for the API client to use
 * Must have a 'class' key, can either be
 * "GithubExtDistProvider" or "GerritExtDistProvider"
 * Common parameters:
 *  'apiUrl' - API url to use with $EXT and $REF variables
 *  'tarballUrl' - API url where tarballs are located
 *  'tarballName' - Expected filename of tarballs
 *  'proxy' - Proxy to use (optional)
 * Github specific parameters:
 *  'token' - An OAuth token for authenticating requests
 * Gerrit specific parameters:
 *  'repoListUrl' - API url to fetch a list of repositories
 * @var array
$wgExtDistAPIConfig = false;

 * File to fetch list of extensions from, with one extension per line
 * Only needed for the Github provider
 * Example url: https://gerrit.wikimedia.org/mediawiki-extensions.txt
$wgExtDistListFile = false;

 * Supported branches/tags, master is the default (and shouldn't be removed)
$wgExtDistSnapshotRefs = array(

 * Snapshot branch/tag to default to
$wgExtDistDefaultSnapshot = 'master';

You'll need to set up some configuration for the extension to work. For Wikimedia's Gerrit instance, it would look like:

$wgExtDistAPIConfig = array(
	'class' => \MediaWiki\Extension\ExtensionDistributor\Providers\GerritExtDistProvider::class,
	'apiUrl' => 'https://gerrit.wikimedia.org/r/projects/mediawiki%2F$TYPE%2F$EXT/branches',
	'tarballUrl' => 'https://extdist.wmflabs.org/dist/$TYPE/$EXT-$REF-$SHA.tar.gz',
	'tarballName' => '$EXT-$REF-$SHA.tar.gz',
	'repoListUrl' => 'https://gerrit.wikimedia.org/r/projects/?p=mediawiki/$TYPE/',

$wgExtDistSnapshotRefs = array(

The Gerrit provider requires an independent tarball generator, the source code for the one running at extdist.wmflabs.org can be found: https://github.com/wikimedia/labs-tools-extdist
