Detailed Description

InterwikiLookup backed by the interwiki database table or $wgInterwikiCache.

By default this uses the SQL backend (interwiki database table) and includes two levels of caching. When parsing a wiki page, many interwiki lookups may be required and thus there is in-class caching for repeat lookups. To reduce database pressure, there is also WANObjectCache for each prefix.

Optionally, a pregenerated dataset can be statically set via $wgInterwikiCache, in which case there are no calls to either database or WANObjectCache.

Member Function Documentation

◆ buildCdbHash()

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

static

Build an array in the format accepted by $wgInterwikiCache.

Given the array returned by getAllPrefixes(), build a PHP array 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.
