1e9efeeb22 986. [bug] 'additional-from-auth no;' did not work reliably 
in the case of queries answered from the cache.

06a960c681 971. [func] 'try-edns' can be use to disable edns on all queries. 2001-08-30 05:52:18 +00:00

135c1c53b8 don't INSIST() that calling dns_db_find() on the root hints 
only binds the rdataset when returning ISC_R_SUCCESS, because that's not the case -
for example, if the root hints are '. 300 IN CNAME .', DNS_R_CNAME is returned and
the rdataset is bound

5465e5f7dd query_getzonedb() formatted the domain name and class being queried 
for at least once for every query to authoritative data, whether or not a log
message was actually printed, which adversely affected query performance

3242899a56 818. [bug] Certain pathological responses to ANY queries could 
cause an assertion failure. [RT #1218]

aed6a8ed2e 805. [bug] When using "forward only", missing root hints should 
not cause queries to fail. [RT #1143]

55ddb88e53 803. [bug] Treat all SIG queries as if they have the CD bit set, 
otherwise no data will be returned [RT #749]

b0390aab30 783. [bug] Following CNAMEs could cause an assertion failure 
when either using an sdb database or under very
                        rare conditions.

40fab71b52 When querying for ANY at a zone apex, don't add NS records to the authority 
section, since they're already in the answer section.

b270a97754 Fix a case where the client could theoretically not free a temporary name. 
It'll never happen, since dns_rdata_tostruct() cannot fail when passed a NULL
mctx, but it's more correct this way.

f915bbfc2d rdatas constructured by query_addcnamelike() always had

3d76b54512 Don't create a timer for every incoming query - only create it for updates, 
notifies, and recursive queries.

75534b6392 optimization: when deciding whether to do v6 syntheis, check the query type 
before the ACL because it's usually faster that way

d29da750d2 statistics counting was slowing down the server. Make client.c:count_query() 
inline and remove dns_stats_ncounters(), which just returned the public
constant DNS_STATS_NCOUNTERS.

634784cb66 701. [func] Root hints are now fully optional. Class IN 
views use compiled-in hints by default, as
                        before.  Non-IN views with no root hints now
                        provide authoritative service but not recursion.
                        A warning is logged if a view has neither root
                        hints nor authoritative data for the root. [RT #696]

576f85e5fd 673. [func] The server can now convert RFC1886-style recursive 
lookup requests into RFC2874-style lookups, when
                        enabled using the new option "allow-v6-synthesis".

b23f160d5b simplified handling of the query type, removing the final 
vestiges of support for multiple queries per packet, in preparation
for AAAA synthesis code which needs to know the query type earlier
than it was previously available

ec772e873b 651. [func] The AD bit in responses now has the meaning

6d5032f9a2 Micro-optimizations: 
- use the DNS_NAME_INIT macro in name.c
	- create dns_name_copy() and use it instead of dns_name_concatenate()
	  when doing a copy.

d3be9a9c6e 583. [func] "rndc querylog" will now toggle logging of 
queries, like "ndc querylog" in BIND 8.

ab13b279ae revert the change of 1.151->1.152 - it is more important to log

include the class in query log messages
