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 three storage backends (SQL, CDB, 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)

Given the array returned by getAllPrefixes(), build a PHP hash which can be given to \Cdb\Reader\Hash() as $this->cdbData, ie as the value of $wgInterwikiCache.
This is used to construct mock interwiki lookup services for testing (in particular, parsertests).
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. |
