440906ce59 INSIST that the rdataset is unassociated. 2001-08-27 03:58:44 +00:00

163e27991b Revert part of the ISC_MAGIC/ISC_MAGIC_VALID change. Because 
common.impmagic is not the first four bytes of the struct,
ISC_MAGIC_VALID() cannot be used.

4e9d4ceadf Take two of new semantics for ANY queries at zone cut points. Now doing 
an ANY query at a zone cut point will return a delegation, except if
DNS_DBFIND_GLUEOK is set, in which case DNS_R_ZONECUT will be returned as
before.  Someday it would probably be a good idea to get rid of DNS_R_ZONECUT
entirely and just return DNS_R_GLUE in that case, but I was afraid to do
that now since it might break things.  These changes pass all system tests.

0d205b805a backed out changes to handling of DNS_DBFIND_VALIDATEGLUE 
option in previous commit - they broke DNS_DBFIND_GLUEOK lookups,
causing several of the system tests to fail

17ed6b7945 when subtracting a nonempty rdataset from a nonexistent rdataset 
and the DNS_DBSUB_EXACT flag, dns_db_subtractrdataset() should return
DNS_R_NOTEXACT, not DNS_R_UNCHANGED.

ed1c40264e sigh. do not set the lock from node->locknum until being sure node is not null 2001-04-20 21:22:09 +00:00
David Lawrence
a0e1f68e14 Now that no_references() reacquires the node lock after deleting the node, 
all of its callers need to maintain a reference to the lock that doesn't
involve looking at node->locknum after no_references() was called.

383b800c62 Fixed up iteration problems related to name cleaning. In a nutshell, 
the node at the end of a chain always needed to have its reference
count incremented, not only when the iterator was paused.  [RT #1007]

85e80b5b69 Remove name/node from the rbtdb in no_references(). 
Iterator uses 'cleaning' flag to expire nodes.

c274e542ad The fixes to return the SIG of a DNAME RR missed one place where 
search.zonecut was set, and consequently we were accessing
search.zonecut_sigrdataset without initializing it.

f4b5a0f434 When a query matched a DNAME in a secure zone, the server did not return the 
signature of the DNAME.  [RT #915]

A query should not match a DNAME whose trust level is pending.  [RT #916]

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.

63ca494e7e Added the isc_refcount_t type, which is a generic locked reference counter, 
and make the rbtdb, zone, and view objects use it.
This should reduce contention on other locks, since (in the normal)
implementation, the reference count has its own lock.  In the future, it
should also be possible to implement an isc_refcount_t with atomic operations
instead of mutexes, which should also help performance.

18d110413c Move dns_dnssec_iszonekey to dns_zonekey_iszonekey, to make the rbtdb not 
require all of dst to be linked in.

6d5032f9a2 Micro-optimizations: 
- use the DNS_NAME_INIT macro in name.c

f8abaa0fae Used a unsigned int rather than a boolean to indicate subtrations making 
the API more consistant between dns_db_{add,subtract}rdataset(),
dns_rdataslab_{merge,subtract}().

Adjust previous CHANGES to reflect above as this is not yet end user visible.

Add missing CHANGES entry for add/merge.

012c6d0b91 585. [func] dns_db_addrdataset() and and dns_rdataslab_merge() 
now support 'exact' additions in a similar manner to
                        dns_db_subtractrdataset() and dns_rdataslab_subtract().

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()),

b55c30f2de 525. [func] New arguement 'exact' for dns_db_subtractrdataset(), 
and dns_rdataslab_subtract() requesting that the RR's
                        must exist prior to deletion.  DNS_R_NOTEXACT is
                        returned if the condition is not met.

7da0286b54 get rid of isc_random_t -- use a wrapper around rand() instead that doesn't do as much work. Also, implement isc_random_jitter(), used to generate a value between a min, max, with a provided jitter value. 2000-09-06 02:40:00 +00:00
