Description Daniel Kinzler 2014-06-16 13:24:07 UTC 
The automatic resolution of double-redirects relies on title-based redirects; but at present, knowing the target title is not sufficient for creating an EntityContent representing a redirect, which also needs the entity ID to be redirected.
Comment 1 Daniel Kinzler 2014-07-30 12:44:21 UTC 
EntityHandle::makeRedirectContent() always fails, since an EntityRedirect needs to know it's own ID. Because of this, the generic method of creating redirects, as used by MediaWiki core, will fail.

Some manual testing revealed to following:

* EntityView can not display entities that *reference* double-redirects (critical, filed as bug 68852)
* maintenance/fixDoubleRedirects.php will skip and report double-redirects of entities.
* Creating a chain of redirects using wbcreateredirect works as expected.
* Automatic creation of redirects on page moves is not an issue, since entity pages cannot be moved.

investigation complete, remaining task is bug 68852.
