I installed pdns-3.0-pre.20110318.2073 from source and converted
from sqlitebackend to sqlite3backend. I'm afraid it shows exactly
the same behaviour.
That is, records are inserted in sqlite3 like this:
345324|373|foo wiki._http._tcp.example.com|SRV|0 80 bar.example.com.|120|0|||
and querying for them results in this being logged:
Received a malformed qdomain from 2001:7b8:2ff:9c::2, 'foo wiki._http._tcp.example.com': sending servfail
Also as a separate issue, sqlite escaping is still not being done
correctly, as per
(Short story is that sqlite does not escape anything except "'",
which it escapes with another "'", not "\".)
