The more generic issue is that there's no way to "get all prefixes" from the Interwiki class, leading the API (and extensions) to just select * from interwiki, which doesn't necessarily work when the cache is being used (eg: WMF).

A) We need a getAllPrefixes() or similar method in Interwiki
B) It would be nice to have native write/edit/delete support for interwiki prefixes in the Interwiki class

Changing to General, this is not an API specific issue.

Introduce Interwiki::getAllPrefixes, fix interwikimap when iw cache is enabled

I have prepared a patch, which allows fetching interwiki map when caching is enabled.

It adds new fields to cache, so dumpInterwiki.php maintenance script needs to be run afterwards.

Raising importance, because several things rely on this and the bug causes serious damage.

Patch applied in r92528 (modified to work with current code).
