73016bd7ef In the case where an rdataset subtraction resulted in the nonexistence 
of the rrset, the subtraction code created a nonexistent rdataset
entry with an incorrect type (the "covers" part of the type was not
set).

535f453de3 The zone node cleaner did least serial number cleaning too soon, which 
could result in the incorrect deletion of the most recent version of a
node when a rollback occurred.

and set paused flag.

1398d0a72d chain->level_matches can be -1 in find_deepest_zonecut() if the node that 
was found is in the topmost tree; so compare > 0 rather than != 0.

cast RBTDB_RDATATYPE_{BASE,EXT}() to dns_rdatatype_t to shut up NT's CL.
The value of each is already suitably bit masked to dns_rdatatype_t size.

#undef IGNORE before making a new definition; CL's winbase.h defines it.

2nd parameter of allocate_version changed from "unsigned int serial" to
"rbtdb_serial_t serial" to have proper sizing when compiled as rbtdb64.c.

cast header->type in two function calls to dns_rdatatype_t.

3c24b4ebae addrdataset() now returns the existing rdataset in addedrdataset if the 
result is DNS_R_UNCHANGED.

Adjust find_deepest_zonecut() to deal with the new treatment of level_matches
by the RBT code.  These changes, combined with the RBT changes, fix a bug
where the wrong delegation was returned if the partial match was a terminal
node in the RBT.

Deal with wildcards of the form *.<zone_origin>.  This stops us from
treating the zone top as a delegation point if wildcards are present.

delegating_type() was erroneously returning true for type NS records in a
cache database.

b7a1d692a1 findnode() result code was still wrong. 1999-08-11 22:08:44 +00:00
Bob Halley
176f7a135e findnode() had design legacies from an older version of the RBT API. It 
also failed to handle the case where it had discovered that a node didn't
exist, had unlocked and relocked the tree (into write mode), and then had
attempted to add the node and got DNS_R_EXISTS as the result.  (I.e. someone
beat us in the race to create the node.)  In this case, an error would have
been returned.  The correct behavior is to succeed (being sure to increment
the node reference count).

87c5f9ae6e subtractrdataset() failed to initialize subresult to NULL 1999-06-30 13:22:44 +00:00
Bob Halley
c95819d75d If the first record in a header chain was marked IGNORE, add() would 
incorrectly treat it as if the IGNORE attribute were not set, and the add
would not work correctly.  Rdatasets marked IGNORE are now ignored.

subtractrdataset() also failed to ignore rdatasets, and didn't cover the
case where the rdataset was marked as nonexistent.
