3f6a666894 Clean up zoneinfo when freeing the entry. This makes more sense, since 
we will always want to do this anyway, and less code duplication means less
places to forget to do it.

25811a89c6 Added dst_digest (a wrapper around digest functions), and dst_s_md5 (an 
internal wrapper around MD5).  Modified hmac-md5 code to use dst_s_md5.

7c03787452 INSIST uint16 range for a call to dns_compress_rollback with int argument. 
Cast int c to char c; it was already range limited.

Cast isc_buffer_uint16 int argument to uint16; it was already range checked.

Cast isc_buffer_uint8 int argument to uint8; it was already range checked.

f0131db6c3 INSIST rdata.length < 65536 before using it in a call to isc_buffer_putuint16. 
I was not entirely sure that all paths to the places where the INSISTS are
would have guaranteed that the unsigned int rdata.length was in the range
of an unsigned short.

Cast bitshifts to isc_uint8_t in encode_win32(); yes, dear compiler, we know
there is a loss of precision.  That's exactly what we want to happen here.

2f6040ed67 Store CNAMEs and their SIGs (if any) in their own name structure on the 
name list.  I.e. do not mix CNAMEs with non-CNAME data.  Do the same thing
for DNAMEs.

92712379fc Updated documentation for chains, level_matches and level_count. 
Updated documentation for dns_rbt_findnode to describe more what
happens with various return values, and that the chain points to the
DNSSEC predecessor for all non-error returns.

New documentation for dns_rbtnodechain_{prev,next}.

Updated documentation for other dns_rbtnodechain_*.

692cae8634 The authority section wasn't being marked for caching. 1999-10-16 20:34:04 +00:00
David Lawrence
401fc772b1 Major: 
deletion bug fixed that could orphan a large section of the tree.  the
  "parent" argument to rotate_left or rotate_right was sometimes not
  really the parent of the rotation vertex, because the parent's parent
  was not correctly reidentified after a rotation done on the parent.

Minor:
  forward static declaration of dns_rbt_printnodename, useful in debugging.

  level_matches set correctly for exact match in dns_rbt_findnode (it was
  one too few, but this was minor because as yet level_matches is only
  used by other code when a partial match was made.

  insist 'node' is a child of 'parent' in rotate_left and rotate_right

  compare a pointer explicitly to NULL that was just "if (pointer)"

  "would would" in a comment changed to just one "would".

added tkey.c.  tkey.c needs some config help before it can be added.
