Brian Wellington f24c135e09 738. [bug] If a non-threadsafe sdb driver supported AXFR and 
received an AXFR request, it would deadlock or die
                        with an assertion failure.
(also some other cleanups)

Brian Wellington 100d0d2ec6 Use a refcount instead of an explicit mutex and integer. 2001-02-13 03:57:06 +00:00
Andreas Gustafsson 8126e45e8c do dns_request_t cancel processing through a control event to 
ensure that dns_dispatch_removeresponse() is called from the correct task
[RT #844]

Brian Wellington 9f708f9014 isc_mem_stats() should print memory statistics even when there are no 
allocated blocks at the time it's called.

Brian Wellington 55f3daa4ea When parsing a message, add an offsets table to each name. Also allow callers 
rendering a message to get temporary offsets tables to attach to names added
to the message.
 2001-02-13 01:02:59 +00:00
Brian Wellington 31efcf6478 Build the offsets table in dns_name_fromwire() while parsing the name, not 
by calling set_offsets.

Andreas Gustafsson ea16b37d71 install refcount.h 2001-02-12 23:11:05 +00:00
Brian Wellington 1f7f8d5c07 Add isc_socket_sendto2() and isc_socket_recv2(). These versions take 
a partially constructed event and flags.  The flags can include
ISC_SOCKFLAG_IMMEDIATE, which means that if the operation completes, the
event is filled in and not sent.
 2001-02-12 21:43:17 +00:00
Brian Wellington a13ca8a125 Add ISC_R_INPROGRESS (operation in progress) 2001-02-12 20:03:16 +00:00
Brian Wellington 29daf5bc77 The suffix returned by dns_compress_findglobal() is never used, so remove it. 2001-02-12 18:07:52 +00:00
Brian Wellington 0c264c9094 The prefix and suffix names used in name compression don't need offset tables, 
since they're never used.  Not having offset tables makes filling in their
contents more efficient.
 2001-02-12 05:22:34 +00:00
Brian Wellington cdc50af0bf In the towire_* and additionaldata_* routines, add an offsets table to names 
passed into dns_name_toregion().  This is effectively free, and reduces the
number of calls to set_offsets() and dns_name_clone() in name compression.

Mark Andrews 9b6398efdf re-do #734 2001-02-12 03:03:40 +00:00
Andreas Gustafsson 6cefb74b2b dns_dispatch_removeresponse() failed to document the 
requirement that it is only called from the task where the
response entry being removed delivers its events (Michael
agrees that this is indeed a requirement)

Brian Wellington 7c3996209b fix a "statement is unreachable" warning 2001-02-11 00:52:31 +00:00
Brian Wellington 7222f9f321 The optimization to avoid compares after hashtable matches didn't work when 
the matched node contained multiple labels.
 2001-02-10 22:46:24 +00:00
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.
 2001-02-10 02:00:11 +00:00
Brian Wellington 64e7f8541d optimization - if the compression table for a message is empty, don't 
hash and look up each label.
 2001-02-10 01:18:19 +00:00
Andreas Gustafsson 1d625775ee note that max_size and target_size apply only when 
ISC_MEM_USE_INTERNAL_MALLOC is set

Andreas Gustafsson dd0ef1a9d3 removed the unused and undocumented functions 
isc_mem_preallocate(), isc_mem_valid(), isc_mem_setsplit(), and
isc_mem_restore()

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

Mark Andrews 80aba3d49a 734. [bug] An attempt to re-lock the zone lock could occur if 
the zone was shutdown during a zone tranfer. [RT #830]

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 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

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
