78d78f05d9 556. [func] The DNSSEC OK bit in the EDNS extended flags 
is now implemented.  Responses to queries without
                        this bit set will not contain any DNSSEC records.

04ab4ecb27 Remove name limits and counter from dig; there's no obvious way to count 
names out of message_parse when PRESERVE_ORDER is set.

c03bb27f06 532. [func] Implement DNS UPDATE pseudo records using 
DNS_RDATA_UPDATE flag.

 531.   [func]          Rdata really should be initalized before being
                        assigned to (dns_rdata_fromwire(), dns_rdata_fromtext(),
                        dns_rdata_clone(), dns_rdata_fromregion()),

digrc filename print length shouldn't be 132

d7a2e05112 Changes which were made on the release branch when Brian and I were reviewing 
dig's code, but never made it down to the mainline.  These are fixes to some
potential bugs Brian noticed.

88aa63f566 Make option processing case sensitive. 
Remove -w option; default xfr's to +nocomments, +noquestion.  Remove wiring
around repeated comment printing, so xfr's with +comments will cause
comment headers to be printed per packet, producing same result as -w
gave.

d97ea44061 Cause -m (memory debugging) option in dig to actually function. 2000-10-16 19:00:01 +00:00
Brian Wellington
e2babfac17 dig now calls isc_mem_stats() only if -m was specified, not if 
isc_mem_debugging was set elsewhere.
 2000-10-13 22:55:50 +00:00
Michael Sawyer
233514c1da Add +besteffort option to dig (on by default) which will cause the 
message parser to accept somewhat malformed packets.
 2000-10-13 17:54:00 +00:00
Michael Sawyer
dc570b92f6 Add support for proposed ZONE and VIEW opt attributes. These are currently 
hidden behind #ifdef's, since no OPT code number has yet to be assigned
by the IANA.  They are also not quite complete in all regards; VIEW
options are understood and ignored.  ZONE options are understood and
acted upon, though some of the error cases aren't quite right.

Remove doubled isc_mem_stats in dighost.c

Update todo list.

Change literal 255's to DNS_NAME_MAXWIRE in name.c
 2000-10-11 17:44:18 +00:00

a6368669a6 '-p' is already taken, -p port. Use '-w' (wire) to print out the packet. 2000-10-03 04:29:08 +00:00
Michael Sawyer
d2792acfaf Add (presently undocumented) -p option to show the begin of each DNS packet, 
useful for AXFR's and similar replies.  (requested by GDIB)

f900be2190 Dig, et al: 
When you have more than 1 nameserver to send queries to,
	send them one at a time with a 1 second wait between transmissions
	instead of just flooding them all out at once.

e412ae947d 482. [bug] nslookup: a plain "server" or "lserver" should be 
treated as a lookup.

strsep() has slightly different semantics to strtok(), use static function
to skip empty tokens.
 2000-09-21 12:25:43 +00:00

This is a fix for the race condition in dig.  It seems to work well, except
there's a memory leak I can't quite track down.  Michael and I will look at
it on the plane ride tommorow, and commit a change via modem once we arrive
in PA.  We'll also be doing general code cleanup.

7efc8c3f69 Megacommit of many files. 
Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const.  Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.

Minor other ISC style cleanups.
