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)

WANObjectCache$objectCacheCache for interwiki info retrieved from the database
HookContainer$hookContainer
ILoadBalancer$loadBalancer
int$objectCacheExpiryExpiry time for $objectCache, in seconds
bool | array$interwikiDataThe pre-generated interwiki data, or false to use the database.
int$interwikiScopesSpecify number of domains to check for messages:

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$allPrefixesAn array of interwiki information such as would be returned by ::getAllPrefixes()
int$scopeThe scope at which to insert interwiki prefixes. See the $interwikiScopes parameter to ::__construct().
?string$thisSite The value of $thisSite, if $scope is 3.
Returns
array A PHP associative array suitable to use as $wgInterwikiCache

◆ fetch()

MediaWiki\Interwiki\ClassicInterwikiLookup::fetch (   $prefix)

Fetch an Interwiki object.

Parameters
string$prefixInterwiki prefix to use
Returns
Interwiki|null|bool

◆ getAllPrefixes()

MediaWiki\Interwiki\ClassicInterwikiLookup::getAllPrefixes (   $local = null)

Returns all interwiki prefixes.

Parameters
string | null$localIf set, limits output to local/non-local interwikis
Returns
array[] Interwiki rows, where each row is an associative array

◆ invalidateCache()

MediaWiki\Interwiki\ClassicInterwikiLookup::invalidateCache (   $prefix)

Purge the in-process and object cache for an interwiki prefix.

Parameters
string$prefix

Implements MediaWiki\Interwiki\InterwikiLookup.

◆ isValidInterwiki()

MediaWiki\Interwiki\ClassicInterwikiLookup::isValidInterwiki (   $prefix)

Check whether an interwiki prefix exists.

Parameters
string$prefixInterwiki prefix to use
Returns
bool Whether it exists

◆ resetLocalCache()

MediaWiki\Interwiki\ClassicInterwikiLookup::resetLocalCache ( )

Resets locally cached Interwiki objects.

This is intended for use during testing only. This does not invalidate entries in the persistent cache, as invalidateCache() does.
