8126e45e8c do dns_request_t cancel processing through a control event to 
ensure that dns_dispatch_removeresponse() is called from the correct task

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

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.

31efcf6478 Build the offsets table in dns_name_fromwire() while parsing the name, not 
by calling set_offsets.

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.

29daf5bc77 The suffix returned by dns_compress_findglobal() is never used, so remove it. 2001-02-12 18:07:52 +00:00

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.

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.

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)

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.

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

9a3ee1570d "hard" errors in accept() were handled really badly. They were logged 
twice, and the socket object for the new socket was never destroyed,
causing the server to hang on exit (if multithreaded) or dump core on exit
(if singlethreaded).  Now the only difference between "hard" and "soft" errors
is that the latter are not logged.

8dab78b566 as a workaround for various OS bugs, do not INSIST() that 
accept() returns a valid peer address; instead just log an ugly error message
and continue if the peer address is left unchanged or insane by accept()

f96ad6baf5 Only check to make sure that the full number of bytes were sent if the 
send operation succeeded.  I'm still not convinced that send_done() works
correctly, but making other changes that look correct causes assertion failures.
