CHANGES

 401.	[func]		Added simple database API.

 400.	[bug]		SIG(0) signing and verifying was done incorrectly.
			[RT #249]

 399.	[bug]		When reloading the server with a config file
			containing a syntax error, it could catch an
			assertion failure trying to perform zone
			maintenance on, or sending notifies from,
			tentatively created zones whose	views were
			never fully configured and lacked an address 
			database and request manager.

 398.	[bug]		"dig" sometimes caught an assertion failure when
			using TSIG, depending on the key length.

 397.	[func]		Added utility functions dns_view_gettsig() and
			dns_view_getpeertsig().

 396.	[doc]		There is now a man page for "nsupdate" 
			in doc/man/bin/nsupdate.8.

 395.	[bug]		nslookup printed incorrect RR type mnemonics
			for RRs of type >= 21 [RT #237].

 394.	[bug]		Current name was not propagated via $INCLUDE.

 393.	[func]		Initial answer while loading (awl) support.
			Entry points: dns_master_loadfileinc(),
			dns_master_loadstreaminc(), dns_master_loadbufferinc().
			Note: calls to dns_master_load*inc() should be rate
			be rate limited so as to not use up all file
			descriptors.

 392.	[func]		Add ISC_R_FAMILYNOSUPPORT.  Returned when OS does
			not support the given address family requested. 

 391.	[clarity]	ISC_R_FAMILY -> ISC_R_FAMILYMISMATCH.

 390.	[func]		The function dns_zone_setdbtype() now takes
			an argc/argv style vector of words and sets 
			both the zone database type and its arguments,
			making the functions dns_zone_adddbarg()
			and dns_zone_cleardbargs() unnecessary.

 389.	[bug]		Attempting to send a reqeust over IPv6 using 
			dns_request_create() on a system without IPv6
			support caused an assertion failure [RT #235].

 388.	[func]		dig and host can now do reverse ipv6 lookups.

 387.	[func]		Add dns_byaddr_createptrname(), which converts
			an address into the name used by a PTR query.

 386.	[bug]		Missing strdup() of ACL name caused random
			ACL matching failures [RT #228].

 385.	[cleanup]	Removed functions dns_zone_equal(), dns_zone_print(),
			and dns_zt_print().

 384.	[bug]		nsupdate was incorrectly limiting TTLs to 65535 instead
			of 2147483647.

 383.	[func]		When writing a master file, print the SOA and NS
			records (and their SIGs) before other records.

 382.	[bug]		named -u failed on many Linux systems where the
			libc provided kernel headers do not match
			the current kernel.

 381.	[bug]		Check for IPV6_RECVPKTINFO and use it instead of
			IPV6_PKTINFO if found. [RT #229]

 380.	[bug]		nsupdate didn't work with IPv6.

 379.	[func]		New library function isc_sockaddr_anyofpf().

 378.	[func]		named and lwresd will log the command line arguments
			they were started with in the "starting ..." message.

 377.	[bug]		When additional data lookups were refused due to 
			"allow-query", the databases were still being
			attached causing reference leaks.

 376.	[bug]		The server should always use good entropy when
			performing cryptographic functions needing entropy.

 375.	[bug]		Per-zone "allow-query" did not properly override the
			view/global one for CNAME targets and additional
			data [RT #220].

 374.	[bug]		SOA in authoritative negative responses had wrong TTL.

 373.	[func]		nslookup is now installed by "make install".

 372.	[bug]		Deal with Microsoft DNS servers appending two bytes of
			garbage to zone transfer requests.

 371.	[bug]		At high debug levels, doing an outgoing zone transfer
			of a very large RRset could cause an assertion failure
			during logging.

 370.	[bug]		The error messages for rollforward failures were
			overly terse.

 369.	[func]		Support new named.conf options, view and zone 
			statements: 

				max-retry-time, min-retry-time, 
				max-refresh-time, min-refresh-time, max-names.

 368.	[func]		Restructure the internal ".bind" view so that more
			zones can be added to it.

 367.	[bug]		Allow proper selection of server on nslookup command
			line.

 366.	[func]		Allow use of '-' batch file in dig for stdin.

 365.	[bug]		nsupdate -k leaked memory.

 364.	[func]		Added additional-from-{cache,auth}

 362.	[bug]		rndc no longer aborts if the configuration file is
			missing an options statement. [RT #209]

 361.	[func]		When the RBT find or chain functions set the name and
			origin for a node that stores the root label
			the name is now set to an empty name, instead of ".",
			to simplify later use of the name and origin by
			dns_name_concatenate(), dns_name_totext() or
			dns_name_format().

 360.	[func]		dns_name_totext() and dns_name_format() now allow
			an empty name to be passed, which is formatted as "@".

 359.	[bug]		dnssec-signzone occasionally signed glue records.

 358.	[cleanup]	Rename the intermediate files used by the dnssec
			programs.

 357.	[bug]		The zone file parser crashed if the argument
			to $INCLUDE was a quoted string.

 356.	[cleanup]	isc_task_send no longer requires event->sender to
			be non-null.

 355.	[func]		Added isc_dir_createunique(), similar to mkdtemp().

 354.	[doc]		Man pages for the dnssec tools are now included in
			the distribution, in doc/man/dnssec.

 353.	[bug]		double increment in lwres/gethost.c:copytobuf().
			(RT# 187)

 352.	[bug]		Race condition in dns_client_t startup could cause
			an assertion failure.

 351.	[bug]		Constructing a response with rcode SERVFAIL to a TSIG
			signed query could crash the server.

 350.	[bug]		Also-notify lists specified in the global options
			block were not correctly reference counted, causing
			a memory leak.

 349.	[bug]		Processing a query with the CD bit set now works
			as expected.

 348.	[func]		New named.conf boolean values 'glue-from-auth' and
			'glue-from-cache' now supported in view and global
			options statement.

 347.	[bug]		Don't crash if when an argument is left off
			options in dig.

 346.	[func]		Add support for .digrc config file, in the
			user's current directory

 345.	[bug]		Large-scale changes/cleanups to dig:
			* Significantly improve structure handling
			* Don't pre-load entire batch files
			* Add name/rr counting/limiting
			* Fix SIGINT handling
			* Shorten timeouts to match v8's behavior

 344.	[bug]		When shutting down, lwresd sometimes tried
			to shut down its client tasks twice,
			triggering an assertion.

 343.	[bug]		Although zone maintenance SOA queries and
			notify requests were signed with TSIG keys
			when configured for the server in case,
			the TSIG was not verified on the response.

 342.	[bug]		The wrong name was being passed to
			dns_name_dup() when generating a TSIG
			key using TKEY.

 341.	[func]		Support 'key' clause in named.conf zone masters
			statement:

				masters {
					10.0.0.1 port 666 key "foo";
					10.0.0.2 ;
				};

 340.	[bug]		The top-level COPYRIGHT file was missing from
			the distribution.

 339.	[bug]		DNSSEC validation of the response to an ANY
			query at a name with a CNAME RR in a secure
			zone triggered an assertion failure.

 338.	[bug]		lwresd logged to syslog as named, not lwresd.

 337.	[bug]		"dig" did not recognize "nsap-ptr" as an RR type
			on the command line.

 336.	[bug]		"dig -f" used 64 k of memory for each line in
			the file.  It now uses much less, though still
			proportionally to the file size.

 335.	[bug]		named would occasionally attempt recursion when
			it was disallowed or undesired.

 334.	[func]		Added hmac-md5 to libisc.

 333.	[bug]		The resolver incorrectly accepted referrals to
			domains that were not parents of the query name,
			causing assertion failures.

 332.	[func]		New function dns_name_reset().

 331.	[bug]		Only log "recursion denied" if RD is set. (RT #178)

 330.	[func]		New function isc_log_wouldlog().

 329.	[func]		omapi_auth_register() now takes a size_t argument for
			the length of a key's secret data.  Previously
			OMAPI only stored secrets up to the first NUL byte.

 328.	[func]		Added isc_base64_decodestring().

 327.	[bug]		rndc.conf parser wasn't correctly recognising an IP
			address where a host specification was required.

 326.	[func]		'keys' in an 'inet' control statement is now
			required and must have at least one item in it.
			A "not supported" warning is now issued if a 'unix'
			control channel is defined.

 325.	[bug]		isc_lex_gettoken was processing octal strings when
			ISC_LEXOPT_CNUMBER was not set.

 324.	[func]		In the resolver, turn EDNS0 off if there is no
			response after a number of retransmissions.
			This is to allow queries some chance of succeeding
			even if all the authoritative servers of a zone
			silently discard EDNS0 requests instead of
			sending an error response like they ought to.

 323.	[bug]		dns_rbt_findname() did not ignore empty rbt nodes.
			Because of this, servers authoritative for a parent
			and grandchild zone but not authoritative for the
			intervening child zone did not correctly issue
			referrals to the servers of the child zone.

 322.	[bug]		Queries for KEY RRs are now sent to the parent
			server before the authoritative one, making
			DNSSEC insecurity proofs work in many cases
			where they previously didn't.

 321.	[bug]		When synthesizing a CNAME RR for a DNAME
			response, query_addcname() failed to intitialize
			the type and class of the CNAME dns_rdata_t,
			causing random failures.

 320.	[func]		Multiple rndc changes: parses an rndc.conf file,
			uses authentication to talk to named, command
			line syntax changed.  This will all be described
			in the ARM.

 319.	[func]		The named.conf "controls" statement is now used
			to configure the OMAPI command channel.

 318.	[func]		dns_c_ndcctx_destroy() could never return anything
			except ISC_R_SUCCESS; made it have void return instead.

 317.	[func]		Use callbacks from libomapi to determine if a
			new connection is valid, and if a key requested
			to be used with that connection is valid.

 316.	[bug]		Generate a warning if we detect an unexpected <eof>
			but treat as <eol><eof>.

 315.	[bug]		Handle non-empty blanks lines. (RT #163)

 314.	[func]		The named.conf controls statement can now have
			more than one key specified for the inet clause.

 313.	[bug]		When parsing resolv.conf, don't terminate on an
			error.	Instead, parse as much as possible, but
			still return an error if one was found.

 312.	[bug]		Increase the number of allowed elements in the
			resolv.conf search path from 6 to 8.  If there
			are more than this, ignore the remainder rather
			than returning a failure in lwres_conf_parse.

 311.	[bug]		lwres_conf_parse failed when the first line of
			resolv.conf was empty or a comment.

 310.	[func]		Changes to named.conf "controls" statement (inet
			subtype only)

			  - support "keys" clause

				controls {
				   inet * port 1024
					allow { any; } keys { "foo"; }
				}

			  - allow "port xxx" to be left out of statement,
			    in which case it defaults to omapi's default port
			    of 953.

 309.	[bug]		When sending a referral, the server did not look
			for name server addresses as glue in the zone
			holding the NS RRset in the case where this zone
			was not the same as the one where it looked for
			name server addresses as authoritative data.

 308.	[bug]		Treat a SOA record not at top of zone as an error
			when loading a zone. (RT #154)

 307.	[bug]		When canceling a query, the resolver didn't check for
			isc_socket_sendto() calls that did not yet have their
			completion events posted, so it could (rarely) end up
			destroying the query context and then want to use
			it again when the send event posted, triggering an
			assertion as it tried to cancel an already-canceled
			query.	(RT #77)

 306.	[bug]		Reading HMAC-MD5 private key files didn't work.

 305.	[bug]		When reloading the server with a config file
			containing a syntax error, it could catch an
			assertion failure trying to perform zone
			maintenance on tentatively created zones whose
			views were never fully configured and lacked
			an address database.

 304.	[bug]		If more than LWRES_CONFMAXNAMESERVERS servers
			are listed in resolv.conf, silently ignore them
			instead of returning failure.

 303.	[bug]		Add additional sanity checks to differentiate a AXFR
			response vs a IXFR response. (RT #157)

 302.	[bug]		In dig, host, and nslookup, MXNAME should be large
			enough to hold any legal domain name in presentation
			format + terminating NULL.

 301.	[bug]		Uninitalised pointer in host:printmessage(). (RT #159)

 300.	[bug]		Using both <isc/net.h> and <lwres/net.h> didn't work
			on platforms lacking IPv6 because each included their
			own ipv6 header file for the missing definitions.  Now
			each library's ipv6.h defines the wrapper symbol of
			the other (ISC_IPV6_H and LWRES_IPV6_H).

 299.	[cleanup]	Get the user and group information before changing the
			root directory, so the administrator does not need to
			keep a copy of the user and group databases in the
			chroot'ed environment.	Suggested by Hakan Olsson.

 298.	[bug]		A mutex deadlock occurred during shutdown of the
			interface manager under certain conditions.
			Digital Unix systems were the most affected.

 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
			an assertion failure.

 296.	[bug]		"make install" from a separate build directory
			failed unless configure had been run in the source
			directory, too.

 295.	[bug]		When invoked with type==CNAME and a message
			not constructed by dns_message_parse(),
			dns_message_findname() failed to find anything
			due to checking for attribute bits that are set
			only in dns_message_parse().   This caused an
			infinite loop when constructing the response to
			an ANY query at a CNAME in a secure zone.

 294.	[bug]		If we run out of space in while processing glue
			when reading a master file and commit "current name"
			reverts to "name_current" instead of staying as
			"name_glue".

 293.	[port]		Add support for FreeBSD 4.0 system tests.

 292.	[bug]		Due to problems with the way some operating systems
			handle simultaneous listening on IPv4 and IPv6
			addresses, the server no longer listens on IPv6
			addresses by default.  To revert to the previous
			behavior, specify "listen-on-v6 { any; };" in
			the config file.

 291.	[func]		Caching servers no longer send outgoing queries
			over TCP just because the incoming recursive query
			was a TCP one.

 290.	[cleanup]	+twiddle option to dig (for testing only) removed.

 289.	[cleanup]	dig is now installed in $bindir instead of $sbindir.
			host is now installed in $bindir.  (Be sure to remove
			any $sbindir/dig from a previous release.)

 288.	[func]		rndc is now installed by "make install" into $sbindir.

 287.	[bug]		rndc now works again as "rndc 127.1 reload" (for
			only that task).  Parsing its configuration file and
			using digital signatures for authentication has been
			disabled until named supports the "controls" statement,
			post-9.0.0.

 286.	[bug]		On Solaris 2, when named inherited a signal state
			where SIGHUP had the SIG_IGN action, SIGHUP would
			be ignored rather than causing the server to reload
			its configuration.

 285.	[bug]		A change made to the dst API for beta4 inadvertently
			broke OMAPI's creation of a dst key from an incoming
			message, causing an assertion to be triggered.	Fixed.

 284.	[func]		The DNSSEC key generation and signing tools now
			generate randomness from keyboard input on systems
			that lack /dev/random.

 283.	[cleanup]	The 'lwresd' program is now a link to 'named'.

 282.	[bug]		The lexer now returns ISC_R_RANGE if parsed integer is
			too big for an unsigned long.

 281.	[bug]		Fixed list of recognized config file category names.

 280.	[func]		Add isc-config.sh, which can be used to more
			easily build applications that link with
			our libraries.

 279.	[bug]		Private omapi function symbols shared between
			two or more files in libomapi.a were not namespace
			protected using the ISC convention of starting with
			the library name and two underscores ("omapi__"...)

 278.	[bug]		bin/named/logconf.c:category_fromconf() didn't take
			note of when isc_log_categorybyname() wasn't able
			to find the category name and would then apply the
			channel list of the unknown category to all categories.

 277.	[bug]		isc_log_categorybyname() and isc_log_modulebyname()
			would fail to find the first member of any category
			or module array apart from the internal defaults.
			Thus, for example, the "notify" category was improperly
			configured by named.

 276.	[bug]		dig now supports maximum sized TCP messages.

 275.	[bug]		The definition of lwres_gai_strerror() was missing
			the lwres_ prefix.

 274.	[bug]		TSIG AXFR verify failed when talking to a BIND 8
			server.

 273.	[func]		The default for the 'transfer-format' option is
			now 'many-answers'.  This will break zone transfers
			to BIND 4.9.5 and older unless there is an explicit
			'one-answer' configuration.

 272.	[bug]		The sending of large TCP responses was canceled
			in mid-transmission due to a race condition
			caused by the failure to set the client object's
			"newstate" variable correctly when transitioning
			to the "working" state.

 271.	[func]		Attempt to probe the number of cpus in named
			if unspecified rather than defaulting to 1.

 270.	[func]		Allow maximum sized TCP answers.

 269.	[bug]		Failed DNSSEC validations could cause an assertion
			failure by causing clone_results() to be called with
			with hevent->node == NULL.

 268.	[doc]		A plain text version of the Administrator
			Reference Manual is now included in the distribution,
			as doc/arm/Bv9ARM.txt.

 267.	[func]		Nsupdate is now provided in the distribution.

 266.	[bug]		zone.c:save_nsrrset() node was not initalized.

 265.	[bug]		dns_request_create() now works for TCP.

 264.	[func]		Dispatch can not take TCP sockets in connecting
			state.	Set DNS_DISPATCHATTR_CONNECTED when calling
			dns_dispatch_createtcp() for connected TCP sockets
			or call dns_dispatch_starttcp() when the socket is
			connected.

 263.	[func]		New logging channel type 'stderr'

				channel some-name {
					stderr;
					severity error;
				}

 262.	[bug]		'master' was not initalized in zone.c:stub_callback().

 261.	[func]		Add dns_zone_markdirty().

 260.	[bug]		Running named as a non-root user failed on Linux
			kernels new enough to support retaining capabilities
			after setuid().

 259.	[func]		New random-device and random-seed-file statements
			for global options block of named.conf. Both accept
			a single string argument.

 258.	[bug]		Fixed printing of lwres_addr_t.address field.

 257.	[bug]		The server detached the last zone manager reference
			too early, while it could still be in use by queries.
			This manifested itself as assertion failures during the
			shutdown process for busy name servers (RT #133).

 256.	[func]		isc_ratelimiter_t now has attach/detach semantics, and
			isc_ratelimiter_shutdown guarantees that the rate
			limiter is detached from its task.

 255.	[func]		New function dns_zonemgr_attach().

 254.	[bug]		Suppress "query denied" messages on additional data
			lookups.

	--- 9.0.0b4 released ---

 253.	[func]		resolv.conf parser now recognises ';' and '#' as
			comments (anywhere in line, not just as the beginning).

 252.	[bug]		resolv.conf parser mishandled masks on sortlists.
			It also aborted when an unrecognized keyword was seen,
			now it silently ignores the entire line.

 251.	[bug]		lwresd caught an assertion failure on startup.

 250.	[bug]		fixed handling of size+unit when value would be too
			large for internal representation.

 249.	[cleanup]	max-cache-size config option now takes a size-spec
			like 'datasize', except 'default' is not allowed.

 248.	[bug]		global lame-ttl option was not being printed when
			config structures were written out.

 247.	[cleanup]	Rename cache-size config option to max-cache-size.

 246.	[func]		Rename global option cachesize to cache-size and
			add corresponding option to view statement.

 245.	[bug]		If an uncompressed name will take more than 255
			bytes and the buffer is sufficiently long,
			dns_name_fromwire should return DNS_R_FORMERR,
			not ISC_R_NOSPACE.  This bug caused cause the
			server to catch an assertion failure when it
			received a query for a name longer than 255
			bytes.

 244.	[bug]		empty named.conf file and empty options statement are
			now parsed properly.

 243.	[func]		new cachesize option for named.conf

 242.	[cleanup]	fixed incorrect warning about auth-nxdomain usage.

 241.	[cleanup]	nscount and soacount have been removed from the
			dns_master_*() arguement lists.

 240.	[func]		databases now come in three flavours: zone, cache
			and stub.

 239.	[func]		If ISC_MEM_DEBUG is enabled, the variable
			isc_mem_debugging controls whether messages
			are printed or not.

 238.	[cleanup]	A few more compilation warnings have been quieted:
			+ missing sigwait prototype on BSD/OS 4.0/4.0.1.
			+ PTHREAD_ONCE_INIT unbraced initializer warnings on
				Solaris 2.8.
			+ IN6ADDR_ANY_INIT unbraced initializer warnings on
				BSD/OS 4.*, Linux and Solaris 2.8.

 237.	[bug]		If connect() returned ENOBUFS when the resolver was
			initiating a TCP query, the socket didn't get
			destroyed, and the server did not shut down cleanly.

 236.	[func]		Added new listen-on-v6 config file statement.

 235.	[func]		Consider it a config file error if a listen-on
			statement has an IPv6 address in it, or a
			listen-on-v6 statement has an IPv4 address in it.

 234.	[bug]		Allow a trusted-key's first field (domain-name) be
			either a quoted or an unquoted string, instead of
			requiring a quoted string.

 233.	[cleanup]	Convert all config structure integer values to unsigned
			integer (isc_uint32_t) to match grammer.

 232.	[bug]		Allow slave zones to not have a file.

 231.	[func]		Support new 'port' clause in config file options
			section. Causes 'listen-on', 'masters' and
			'also-notify' statements to use its value instead of
			default (53).

 230.	[func]		Replace the dst sign/verify API with a cleaner one.

 229.	[func]		Support config file sig-validity-interval statement
			in options, views and zone statements (master
			zones only).

 228.	[cleanup]	Logging messages in config module stripped of
			trailing period.

 227.	[cleanup]	The enumerated identifiers dns_rdataclass_*,
			dns_rcode_*, dns_opcode_*, and dns_trust_* are
			also now cast to their appropriate types, as with
			dns_rdatatype_* in item number 225 below.

 226.	[func]		dns_name_totext() now always prints the root name as
			'.', even when omit_final_dot is true.

 225.	[cleanup]	The enumerated dns_rdatatype_* identifiers are now
			cast to dns_rdatatype_t via macros of their same name
			so that they are of the proper integral type wherever
			a dns_rdatatype_t is needed.

 224.	[cleanup]	The entire project builds cleanly with gcc's
			-Wcast-qual and -Wwrite-strings warnings enabled,
			which is now the default when using gcc.  (Warnings
			from confparser.c, because of yacc's code, are
			unfortunately to be expected.)

 223.	[func]		Several functions were reprototyped to qualify one
			or more of their arguments with "const".  Similarly,
			several functions that return pointers now have
			those pointers qualified with const.

 222.	[bug]		The global 'also-notify' option was ignored.

 221.	[bug]		An uninitialized variable was sometimes passed to
			dns_rdata_freestruct() when loading a zone, causing
			an assertion failure.

 220.	[cleanup]	Set the default outgoing port in the view, and
			set it in sockaddrs returned from the ADB.
			[31-May-2000 explorer]

 219.	[bug]		Signed truncated messages more correctly follow
			the respective specs.

 218.	[func]		When an rdataset is signed, its ttl is normalized
			based on the signature validity period.

 217.	[func]		Also-notify and trusted-keys can now be used in
			the 'view' statement.

 216.	[func]		The 'max-cache-ttl' and 'max-ncache-ttl' options
			now work.

 215.	[bug]		Failures at certain points in request processing
			could cause the assertion INSIST(client->lockview
			== NULL) to be triggered.

 214.	[func]		New public function isc_netaddr_format(), for
			formatting network addresses in log messages.

 213.	[bug]		Don't leak memory when reloading the zone if
			an update-policy clause was present in the old zone.

 212.	[func]		Added dns_message_get/settsigkey, to make TSIG
			key management reasonable.

 211.	[func]		The 'key' and 'server' statements can now occur
			inside 'view' statements.

 210.	[bug]		The 'allow-transfer' option was ignored for slave
			zones, and the 'transfers-per-ns' option was
			was ignored for all zones.

 209.	[cleanup]	Upgraded openssl files to new version 0.9.5a

 208.	[func]		Added ISC_OFFSET_MAXIMUM for the maximum value
			of an isc_offset_t.

 207.	[func]		The dnssec tools properly use the logging subsystem.

 206.	[cleanup]	dst now stores the key name as a dns_name_t, not
			a char *.

 205.	[cleanup]	On IRIX, turn off the mostly harmless warnings 1692
			("prototyped function redeclared without prototype")
			and 1552 ("variable ... set but not used") when
			compiling in the lib/dns/sec/{dnssafe,openssl}
			directories, which contain code imported from outside
			sources.

 204.	[cleanup]	On HP/UX, pass +vnocompatwarnings to the linker
			to quiet the warnings that "The linked output may not
			run on a PA 1.x system."

 203.	[func]		notify and zone soa queries are now tsig signed when
			appropriate.

 202.	[func]		isc_lex_getsourceline() changed from returning int
			to returning unsigned long, the type of its underlying
			counter.

 201.	[cleanup]	Removed the test/sdig program, it has been
			replaced by bin/dig/dig.


	--- 9.0.0b3 released ---

 200.	[bug]		Failures in sending query responses to clients
			(e.g., running out of network buffers) were
			not logged.

 199.	[bug]		isc_heap_delete() sometimes violated the heap
			invariant, causing timer events not to be posted
			when due.

 198.	[func]		Dispatch managers hold memory pools which
			any managed dispatcher may use.	 This allows
			us to avoid dipping into the memory context for
			most allocations.  [19-May-2000 explorer]

 197.	[bug]		When an incoming AXFR or IXFR completes, the
			zone's internal state is refreshed from the
			SOA data.  [19-May-2000 explorer]

 196.	[func]		Dispatchers can be shared easily between views
			and/or interfaces.  [19-May-2000 explorer]

 195.	[bug]		Including the NXT record of the root domain
			in a negative response caused an assertion
			failure.

 194.	[doc]		The PDF version of the Administrator's Reference
			Manual is no longer included in the ISC BIND9
			distribution.

 193.	[func]		changed dst_key_free() prototype.

 192.	[bug]		Zone configuration validation is now done at end
			of config file parsing, and before loading
			callbacks.

 191.	[func]		Patched to compile on UnixWare 7.x.  This platform
			is not directly supported by the ISC.

 190.	[cleanup]	The DNSSEC tools have been moved to a separate
			directory dnssec/ and given the following new,
			more descriptive names:

			      dnssec-keygen
			      dnssec-signzone
			      dnssec-signkey
			      dnssec-makekeyset

			Their command line arguments have also been changed to
			be more consistent.  dnssec-keygen now prints the
			name of the generated key files (sans extension)
			on standard output to simplify its use in automated
			scripts.

 189.	[func]		isc_time_secondsastimet(), a new function, will ensure
			that the number of seconds in an isc_time_t does not
			exceed the range of a time_t, or return ISC_R_RANGE.
			Similarly, isc_time_now(), isc_time_nowplusinterval(),
			isc_time_add() and isc_time_subtract() now check the
			range for overflow/underflow.  In the case of
			isc_time_subtract, this changed a calling requirement
			(ie, something that could generate an assertion)
			into merely a condition that returns an error result.
			isc_time_add() and isc_time_subtract() were void-
			valued before but now return isc_result_t.

 188.	[func]		Log a warning message when an incoming zone transfer
			contains out-of-zone data.

 187.	[func]		isc_ratelimter_enqueue() has an additional arguement
			'task'.

 186.	[func]		dns_request_getresponse() has an additional arguement
			'preserve_order'.

 185.	[bug]		Fixed up handling of ISC_MEMCLUSTER_LEGACY.  Several
			public functions did not have an isc__ prefix, and
			referred to functions that had previously been
			renamed.

 184.	[cleanup]	Variables/functions which began with two leading
			underscores were made to conform to the ANSI/ISO
			standard, which says that such names are reserved.

 183.	[func]		ISC_LOG_PRINTTAG option for log channels.  Useful
			for logging the program name or other identifier.

 182.	[cleanup]	New commandline parameters for dnssec tools

 181.	[func]		Added dst_key_buildfilename and dst_key_parsefilename

 180.	[func]		New isc_result_t ISC_R_RANGE.  Supersedes DNS_R_RANGE.

 179.	[func]		options named.conf statement *must* now come
			before any zone or view statements.

 178.	[func]		Post-load of named.conf check verifies a slave zone
			has non-empty list of masters defined.

 177.	[func]		New per-zone boolean:

				enable-zone yes | no ;

			intended to let a zone be disabled without having
			to comment out the entire zone statement.

 176.	[func]		New global and per-view option:

				max-cache-ttl number

 175.	[func]		New global and per-view option:

				additional-data internal | minimal | maximal;

 174.	[func]		New public function isc_sockaddr_format(), for
			formatting socket addresses in log messages.

 173.	[func]		Keep a queue of zones waiting for zone transfer
			quota so that a new transfer can be dispatched
			immediately whenever quota becomes available.

 172.	[bug]		$TTL directive was sometimes missing from dumped
			master files because totext_ctx_init() failed to
			initialize ctx->current_ttl_valid.

 171.	[cleanup]	On NetBSD systems, the mit-pthreads or
			unproven-pthreads library is now always used
			unless --with-ptl2 is explicitly specified on
			the configure command line.  The
			--with-mit-pthreads option is no longer needed
			and has been removed.

 170.	[cleanup]	Remove inter server consistancy checks from zone,
			these should return as a seperate module in 9.1.
			dns_zone_checkservers(), dns_zone_checkparents(),
			dns_zone_checkchildren(), dns_zone_checkglue().

			Remove dns_zone_setadb(), dns_zone_setresolver(),
			dns_zone_setrequestmgr() these should now be found
			via the view.

 169.	[func]		ratelimiter can now process N events per interval.

 168.	[bug]		include statements in named.conf caused syntax errors
			due to not consuming the semicolon ending the include
			statement before switching input streams.

 167.	[bug]		Make lack of masters for a slave zone a soft error.

 166.	[bug]		Keygen was overwriting existing keys if key_id
			conflicted, now it will retry, and non-null keys
			with key_id == 0 are not generated anymore.  Key
			was not able to generate NOAUTHCONF DSA key,
			increased RSA key size to 2048 bits.

 165.	[cleanup]	Silence "end-of-loop condition not reached" warnings
			from Solaris compiler.

 164.	[func]		Added functions isc_stdio_open(), isc_stdio_close(),
			isc_stdio_seek(), isc_stdio_read(), isc_stdio_write(),
			isc_stdio_flush(), isc_stdio_sync(), isc_file_remove()
			to encapsulate nonportable usage of errno and sync.

 163.	[func]		Added result codes ISC_R_FILENOTFOUND and
			ISC_R_FILEEXISTS.

 162.	[bug]		Ensure proper range for arguments to ctype.h functions.

 161.	[cleanup]	error in yyparse prototype that only HPUX caught.

 160.	[cleanup]	getnet*() are not going to be implemented at this
			stage.

 159.	[func]		Redefinition of config file elements is now an
			error (instead of a warning).

 158.	[bug]		Log channel and category list copy routines
			weren't assigning properly to output parameter.

 157.	[port]		Fix missing prototype for getopt().

 156.	[func]		Support new 'database' statement in zone.

				database "quoted-string";

 155.	[bug]		ns_notify_start() was not detaching the found zone.

 154.	[func]		The signer now logs libdns warnings to stderr even when
			not verbose, and in a nicer format.

 153.	[func]		dns_rdata_tostruct() 'mctx' is now optional.  If 'mctx'
			is NULL then you need to preserve the 'rdata' until
			you have finished using the structure as there may be
			references to the associated memory.  If 'mctx' is
			non-NULL it is guaranteed that there are no references
			to memory associated with 'rdata'.

			dns_rdata_freestruct() must be called if 'mctx' was
			non-NULL and may safely be called if 'mctx' was NULL.

 152.	[bug]		keygen dumped core if domain name argument was omitted
			from command line.

 151.	[func]		Support 'disabled' statement in zone config (causes
			zone to be parsed and then ignored). Currently must
			come after the 'type' clause.

 150.	[func]		Support optional ports in masters and also-notify
			statements:

				masters [ port xxx ] { y.y.y.y [ port zzz ] ; }

 149.	[cleanup]	Removed usused argument 'olist' from
			dns_c_view_unsetordering().

 148.	[cleanup]	Stop issuing some warnings about some configuration
			file statements that were not implemented, but now are.

 147.	[bug]		Changed yacc union size to be smaller for yaccs that
			put yacc-stack on the real stack.

 146.	[cleanup]	More general redundant header file cleanup.  Rather
			than continuing to itemize every header which changed,
			this changelog entry just notes that if a header file
			did not need another header file that it was including
			in order to provide its advertized functionality, the
			inclusion of the other header file was removed.	 See
			util/check-includes for how this was tested.

 145.	[cleanup]	Added <isc/lang.h> and ISC_LANG_BEGINDECLS/
			ISC_LANG_ENDDECLS to header files that had function
			prototypes, and removed it from those that did not.

 144.	[cleanup]	libdns header files too numerous to name were made
			to conform to the same style for multiple inclusion
			protection.

 143.	[func]		Added function dns_rdatatype_isknown().

 142.	[cleanup]	<isc/stdtime.h> does not need <time.h> or
			<isc/result.h>.

 141.	[bug]		Corrupt requests with multiple questions could
			cause an assertion failure.

 140.	[cleanup]	<isc/time.h> does not need <time.h> or <isc/result.h>.
