Detailed Description

InterwikiLookup implementing the "classic" interwiki storage (hardcoded up to MW 1.26).

This implements two levels of caching (in-process array and a WANObjectCache) and two storage backends (SQL and plain PHP arrays).

All information is loaded on creation when called by $this->fetch( $prefix ). All work is done on replica DB, because this should never change (except during schema updates etc, which aren't wiki-related)

Since: 1.28

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Interwiki\ClassicInterwikiLookup::__construct	(	Language	$contLang,
		WANObjectCache	$objectCache,

	)

Parameters

Language	$contLang	Language object used to convert prefixes to lower case
WANObjectCache	$objectCache	Cache for interwiki info retrieved from the database
HookContainer	$hookContainer
ILoadBalancer	$loadBalancer
int	$objectCacheExpiry	Expiry time for $objectCache, in seconds
bool \| array	$interwikiData	The pre-generated interwiki data, or false to use the database.
int	$interwikiScopes	Specify number of domains to check for messages: 1: Just local wiki level 2: wiki and global levels 3: site level as well as wiki and global levels

Member Function Documentation

◆ buildCdbHash()

static MediaWiki\Interwiki\ClassicInterwikiLookup::buildCdbHash	(	array	$allPrefixes,
		int	$scope = `1`,
		?string	$thisSite = `null`
	)

static

Given the array returned by getAllPrefixes(), build a PHP hash which can be given to self::__construct() as $interwikiData, i.e.

as the value of $wgInterwikiCache. This is used to construct mock interwiki lookup services for testing (in particular, parsertests).

Parameters

array	$allPrefixes	An array of interwiki information such as would be returned by ::getAllPrefixes()
int	$scope	The scope at which to insert interwiki prefixes. See the $interwikiScopes parameter to ::__construct().
	?string	$thisSite The value of $thisSite, if $scope is 3.
