c569a0e4d5 1582. [bug] rrset-order failed to work on RRsets with more 
than 32 elements. [RT #10381]

507102c95a In dns_compress_invalidate(), cctx->table cannot be NULL, since it's part of 
the cctx structure.

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

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

5d18f1205a remove the call to dns_name_getlabel(), since the dns_name_toregion() macro 
is faster.

1c33761bcf Minor optimization - use the number of labels in the prefix as the loop 
counter, not the number of labels in the name.

575737b964 Rewrite the name compression code to use a hashtable instead of an RBT and 
avoid allocating memory in most cases.  This increases performance by
about 225% on the rc query test (~305 q/s to 990 q/s).

942d1a339b Decompression contexts now take a type instead of the "strict" boolean 
value - the type can be "any", "strict", or "none".  This fixes potential
problems with compression in unknown rr types.

40f53fa8d9 Trailing whitespace trimmed. Perhaps running "perl util/spacewhack.pl in your 
own CVS tree will help minimize CVS conflicts.  Maybe not.
Blame Graff for getting me to trim all trailing whitespace.

1a69a1a78c Megacommit of dozens of files. 
Cleanup of redundant/useless header file inclusion.

ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
   /*
    * This is a comment.
    */

35c0626628 Don't ever send GLOBAL16 compression, not even if edns>=1. Since the 
edns1 I-D has expired, no one knows what edns level 1 will mean, and it may end up not
implying support for GLOBAL16.  We are still liberal in what we accept; GLOBAL16
is accepted in packets we receive.

94a08e09db Check for edns1 and strict decompression once and for all in 
dns_[de]compress_setmethods instead of separately in every caller

09f22ac5b0 Redundant header work, mostly removing <dns/result.h> from installed

6e49e91bd0 103. [func] libisc buffer API changes for <isc/buffer.h>: 
Added:
                                isc_buffer_base(b)          (pointer)
                                isc_buffer_current(b)       (pointer)
                                isc_buffer_active(b)        (pointer)
                                isc_buffer_used(b)          (pointer)
                                isc_buffer_length(b)            (int)
                                isc_buffer_usedlength(b)        (int)
                                isc_buffer_consumedlength(b)    (int)
                                isc_buffer_remaininglength(b)   (int)
                                isc_buffer_activelength(b)      (int)
                                isc_buffer_availablelength(b)   (int)
                        Removed:
                                ISC_BUFFER_USEDCOUNT(b)
                                ISC_BUFFER_AVAILABLECOUNT(b)
                                isc_buffer_type(b)
                        Changed names:
                                isc_buffer_used(b, r) ->
                                        isc_buffer_usedregion(b, r)
                                isc_buffer_available(b, r) ->
                                        isc_buffer_available_region(b, r)
                                isc_buffer_consumed(b, r) ->
                                        isc_buffer_consumedregion(b, r)
                                isc_buffer_active(b, r) ->
                                        isc_buffer_activeregion(b, r)
                                isc_buffer_remaining(b, r) ->
                                        isc_buffer_remainingregion(b, r)

                        Buffer types were removed, so the ISC_BUFFERTYPE_*
                        macros are no more, and the type argument to
                        isc_buffer_init and isc_buffer_allocate were removed.
                        isc_buffer_putstr is now void (instead of isc_result_t)
                        and requires that the caller ensure that there
                        is enough available buffer space for the string.

eca5913a47 Made calls to dns_rbt_find{name,node} compatible with the just-committed 
changes to rbt.c by passing a NULL pointer for the dns_name_t that
receives the full name of the node that is found.  There is probably something
better to do, but this just keeps things compiling.

587fc7b519 Revised dns_rbt_findname and dns_rbt_findnode to find the closest match 
when an exact match cannot be found.  This changed the calling interface,
which necessitated changes to rbtdb.c and compress.c.

518be7faab dns_name_cat() -> dns_name_concatenate() 
Changed behaviour so that it is intuitive w.r.t. absolute names.
	If 'prefix' is absolute then 'suffix' must be NULL.
	If 'prefix' or 'suffix' is absolute then the result is absolute.
