Brian Wellington 82ecc44b96 another micro-optimization. 2001-02-10 02:55:05 +00:00
Brian Wellington 319d2971f1 When the client informs the dispatcher of a received response, have the 
dispatcher copy the event instead of reusing the original one.

Brian Wellington 64e7f8541d optimization - if the compression table for a message is empty, don't 
hash and look up each label.

Brian Wellington 1c1f5e1911 The root node was added to the hashtable twice, which could lead to an 
infinite loop. [RT #840]

Brian Wellington 2d6a6174f1 micro-optimizations 2001-02-09 02:13:07 +00:00
Brian Wellington 65bc8f2af8 When assigning a bucket lock to an rbt node, use the hash of the full name, 
rather than the hash of the partial name stored in the node.  This more
evenly distributes nodes across locks.

This change only takes effect when DNS_RBT_USEHASH is defined, and also changes
the rbt so that the hashtable is created when the first node is created in the
tree, not after 64 nodes are added.

Andreas Gustafsson 97f26b88f6 removed more needless attaching and detaching of the blackhole ACL 2001-02-09 00:23:16 +00:00
Andreas Gustafsson a349fd680c removed all code for maintaining a 'goodness' value in the adb, 
since it was never used and Michael thinks 'it should probably be removed'.

Andreas Gustafsson aa23a35d81 733. [bug] Reference counts of dns_acl_t objects need to be 
locked but were not. [RT #801]

Bob Halley 22457624d3 deal with 0 TTL glue 2001-02-08 19:14:58 +00:00
Andreas Gustafsson 8ed67113ec there is no need for each dispatch to have a separate reference to 
the blackhole list; they can use the blackhole list of the dispatch
manager directly. This eliminates some unsafe unlocked accesses to
the reference count of the blackhole list dns_acl_t object

Brian Wellington c716477d2e don't free the structure twice (thanks, Andreas) 2001-02-05 20:29:56 +00:00
Brian Wellington 15bc0af6a1 chain_name() built the fully qualified name in a very inefficient way. 
Reversing the order of the concatenations makes it significantly faster.

Mark Andrews 8e68489885 722. [func] Allow n/named/server.cincrememtal loads to be canceled. 
721.   [cleanup]       Load manager and dns_master_loadfilequota() are no

Andreas Gustafsson 2571d4a73d make sanitation work when building into a separate build directory 
directly from a CVS tree [RT #765]; also removed code for removing "#line" directives and the

Andreas Gustafsson 8d5ec7195a new dns_master_load() option DNS_MASTER_NOINCLUDE 2001-01-30 23:12:27 +00:00
Andreas Gustafsson 651421a5db removed the "additional-data" option, since it was never 
fully implemented and because it causes "internal" to be a reserved word in
named.conf, causing problems for those using "internal" as an ACL name.
Since additional-data was never documented, the user-visible aspect of the
change is:

 718.   [cleanup]       "internal" is no longer a reserved word in named.conf.

Andreas Gustafsson dfa0badebe 715. [bug] Resolving some A6 chains could cause an assertion 
failure in adb.c. [RT #738]
 2001-01-30 05:56:58 +00:00
Brian Wellington 63ca494e7e Added the isc_refcount_t type, which is a generic locked reference counter, 
and make the rbtdb, zone, and view objects use it.
This should reduce contention on other locks, since (in the normal)
implementation, the reference count has its own lock.  In the future, it
should also be possible to implement an isc_refcount_t with atomic operations
instead of mutexes, which should also help performance.

Brian Wellington 94baac869a 712. [bug] Sending a large signed update message caused an 
assertion failure. [RT #718]

- Resetting a message should clear the TSIG/SIG(0) sections
- Rerendering a message if the first try returned USETCP should not call
  dns_message_settsigkey() again.

Brian Wellington 35f06ab0e6 Clients now listen on sockets instead of accepting queries from dispatchers. 
When a socket is shared by clients and query-source, the client hands off
responses to the dispatcher.

Brian Wellington 7b5172166d Waking up once a second to clean one bucket is excessive. Change the 
default values (and dependencies) so that the clenup routine is called once
ever 30 seconds and cleans 8-9 buckets.

Brian Wellington 9f7b524522 The forwarders statements in zones & views didn't work. 2001-01-25 21:10:18 +00:00
Brian Wellington 330705066b Wrap inet_ntop() and use that in the _totext() functions. The wrapper calls 
inet_ntop() and copies the output (but not the trailing null) into the buffer.
