There was a problem hiding this comment.
Is this sound? I see LookupIterator::Next() has a DCHECK_NE(JSPROXY, state_) but if I read JSObject::AllCanRead() right, it can stop at a JSPROXY instance. It seems like the logic should be:
if (has_access) it->Next();There was a problem hiding this comment.
The access check is on the object_template, which is created by the embedder. We cannot configure templates as JSProxies. I'd say it's sound.

This fix is needed to use the GenericNamedPropertyDescriptorCallback on the global object in node_contextify.cc.
5.6 is not maintained anymore, therefore not backmerged upstream.
