add database API methods needed for loading rdatasets into memory (currentversion, beginload, endload), plus the methods used by zone_postload() for zone consistency checks (getoriginnode, find, findnode, findrdataset, attachnode, detachnode, deletedata). the QP trie doesn't support the find callback mechanism available in dns_rbt_findnode() which allows examination of intermediate nodes while searching, so the detection of wildcard and delegation nodes is now done by scanning QP chains after calling dns_qp_lookup(). Note that the lookup in previous_closest_nsec() cannot return ISC_R_NOTFOUND. In RBTDB, we checked for this return value and ovewrote the result with ISC_R_NOMORE if it occurred. In the qpzone implementation, we insist that this return value cannot happen. dns_qp_lookup() would only return ISC_R_NOTFOUND if we asked for a name outside the zone's authoritative domain, and we never do that when looking up a predecessor NSEC record. named-checkzone is now able to load a zone and check it for errors, but cannot dump it. |
