In #2267 I noticed the new in-memory zone loader doesn't support
the case where RRSIG is added without having the corresponding
covered RRset. It's almost a broken setup, but I actually intended to
allow such cases originally. That may become a more practical issue
when we support incremental updates (after IXFR-in or DDNS), where
there may be some intermediate state that only RRSIGs are added first
and we cannot predict whether/when the covered RRset comes.

But I didn't support that case in #2267 because from a quick look it
would break some assumption in the finder implementation.

So this ticket will fix both the loader and the finder:

  • the loader just allows this case. It should be an easy update to InMemoryClient::Loader class (of #2267).
  • handle this case in the finder. If, for example, a lookup of results in an RRSIG-only rdataset (which covers type A), it should return NXRRSET.
