**** 0.66 Dec 30, 2009
Feature Truncation for Nameserver
fixes rt.cpan.org #33547 and #42744
TAKE CARE:
this feature may cause unexpected behavior for your nameservers
and can be turned off by setting Truncate to 0 during the creation
of the nameserver.
my $ns = Net::DNS::Nameserver->new(
Truncate => 0,
);
Net::DNS::Packet::truncate is a new method that is called from
within Net::DNS::Nameserver that truncates a packet according to
the rules of RFC2181 section 9.
Acknowledgement Aaron Crane for an elegant test and for
inspiration for a direction.
Feature: Added Net::DNS::Domain
Net::DNS::Domain is an attempt to introduce a consistent model
for representation of RFC 1035 <domain-name>s.
The class and its test script t/02-domain.t are included to be
exposed to various architectures.
The class and its methods may be subject to change, both in terms of
naming and functionality.
A contribution by Dick Franks
Fix improved fuzzy matching of CLASS and TYPE in the Question
constructor method.
A contribution by Dick Franks.

Fix rt.cpan.org #47265 (partial)
Frequently Net:DNS under Windows XP has a UDP problem which is
caused by a buggy implementation of SOCKS under Windows.
One liner added to not continue UDP processing when that happens.
Feature KX RR
Added support for the KX RR, RFC2230
The implementation is trivial since the KX inherits almost all of
its functionality by inheritance from the MX RR.
Fix NSAP RR string representation
RFC1706 specifies the masterfile format to have a leading "0x" and
optional dot. This was not how the RR was represented with the
rdatastr method (and hence string and print).
Fix rt.cpan.org #52307 AAAA v4compat parsing bug
Acknowledgement: BLBLACK
Fix AAAA dynamic update
Dynamic update of AAAA caused FORMERR on the prerequisite caused
by AAAA creating rdata even when an address was never specified.

NOTE rt.cpan.org # 40249
Release 0.62 introduced a feature to parse data inside a packet only
when needed. This can cause the following to happen:
Exception: corrupt or incomplete data at
/usr/lib/perl5/Net/DNS/RR.pm line 510.
caught at -e line 1
This may happen when you have undefined your packet data before all the
sections have been fully parsed. Such as in:
$packet = Net::DNS::Packet->new(\$data);
undef($data);
The workaround is to force parsing by calling the methods that
parse the data. e.g.
$packet = Net::DNS::Packet->new(\$data);
$packet->answer; $packet->additional; $packet->authority;
undef ($data)
Fix rt.cpan.org # 41076 and # 41071

The ReplyHandler now also receives a variable with an anonymous hash with the connection details. Variables
supplied to the Reply handler are: $qname, $qclass, $qtype, $peerhost, $query, $conn
The hash referenced by $conn contains the following buckets: sockhost, sockport, peerhost, and peerport.
Feature t/08-online.t and t/10-recurse.t
In particular environments a query for a.t. will resolve and or
middleboxes will replace DNS packet content for queries to the root.
A bunch of test is skipped when this (broken) environment is
detected.
Feature/Bug rt.cpan.org #22019
The initial fix for rt 22019 was to strip a trailing dot from all
attributes that were provided as argument for the
Net::DNS::RR::new_from_hash function. We have introduced
Net::DNS::stripdot, a function that will strip the dots of domain
names, taking into account possible escapes (e.g. labels like
foo\\\..). As a side effect the new_from_string method will now
convert possible spaces that are not trapped by some of the
new_from_string functions and convert them to \032 escapes.
For information: The internal storage of domain names is using
presentation format without trailing dots.
Bug
@EXPORT and @EXPORT_OK moved to a BEGIN block so that Net::DNS::SEC
can make use of exported functions
Feature/Bug
The Notify handler introduced in 0.63 did not set the OPCODE on the
reply appropriately. This has been solved generically by allowing the
"Headermask" that is returned as 4th element by the reply or notify
handler in the nameserver also allows for the opcode to be set.
e.g. as in return ("NXDOMAIN",[],[],[],{ opcode => "NS_NOTIFY_OP" }
);
*** 0.63, 8 Feb 2008
This version contains a Security Fix.
Feature NotifyHandler in Nameserver
The NotifyHandler is a new attribute to the nameserver used in the
same way as the ReplyHandler except that it is executed when the
opcode is NS_NOTIFY (RFC1996). It takes the same arguments as the
reply handler (i.e. $qname, $qclass, $qtype, $peerhost, and $query).
Corrections made in the documentation.

response (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-6341). Packet
parsing routines are now enclosed in eval blocks to trap exception
and avoid premature termination of user program.
Bug: mbox-dname and txt-dname were not allowed to be empty in the RP RR.
Fix by Peter Koch
*** 0.62, 28 December 2007
Features: Move of some functionality out of the Packet to the Question
and RR classes; parsing of elements in the packet is now performed
by calling the appropriate subclasses.
New methods were introduced:
* Net::DNS::Packet->parse()
* Net::DNS::RR->parse()
* Net::DNS::Question->parse()
The Packet class now defers parsing of authority/additional until
their content is really needed. This should cause a bit of
performance improvement.
Dick Franks is acknowledged for this Good Work (TM).
Added 20081216 see NOTE above under rt.cpan.org # 40249
Feature: the Net::DNS::Packet's answersize() method will from now on
ignore its arguments and just return the size of the packet.
Feature: The Net::DNS::RR->new() method used to call
Net::DNS::RR->new_from_data() whenever called with the appropriate
combination of arguments. That (undocumented) behavior has been deprecated.
Use Net::DNS::RR->new_from_data() directly if you depended on that.
Feature: Net::DNS::Packets unique_push now ignores the TTL in
comparison of uniqueness, this is closer to the intent of
RFC2181, but not yet fully compliant.

Dick Franks supplied an improved version of check_soa script which
performs a direct test of NCACHE TTL by looking up non-existent name and
reporting value if it exceeds 86400. Test is skipped unless minimumTTL is
above same threshold. Recent BIND implementations impose a ceiling on
NCACHE TTLs internally, so a large minimumTTL value is unlikely to have
damaging consequences at many sites.

Dick Franks supplied a cleaned up version of Question.pm.
Revised code deals with incomplete IPv6 address bug and accepts RFC4291
address prefix notation. IPv4/prefix also supported for completeness.
This involved a minor change to the API for reverse IP lookup. Changing
qtype to PTR is now performed for A and AAAA only. This allows queries
for NS and SOA records at interior nodes to be specified using the address
prefix. Type ANY queries now also produce the expected result.
Cleaned up TYPE/CLASS reversal code, exploiting fact that the intersection
of the sets of class and type names contains only one member (ANY).
Minor cleanup of remaining code.
Fix rt.cpan.org #22019

Feature NSEC3PARAM hook
A hook to load NSEC3PARAM when available has been added.
WARNING: Both NSEC3 and NSEC3PARAM are configured with their
experimental type codes.
Feature rt r24525
Net::DNS::Resolver depended on Net::IP (2268 Kb) which depends on
heavy module Math::BigInt (1780 Kb). Valery Studennikov suggested to
ship Net::DNS::Resolver::Base with its own copies of ip_is_ipv[4|6] and
supplied a patch with those functions stripped from Net::IP.
Note that the package still depends on Net::IP because
Net::DNS::Nameserver and a few tests depend on it.

Fix rt.cpan.org 20836, 20857, 20994, and 21402
These tickets all revolved around proper reverse mapping of IPv6
addresses.
Acknowledgments to Dick Franks who has provided elegant solutions and
cleaned a bit of code.
Note that directly calling Question->new() without arguments will
cause the qclass,qtype to be IN, A instead of ANY, ANY.
Net::DNS::Resolver's search() method would always gracefully
interpret a qname in the form of an IPv4 address. It would go out
and do a PTR query in the reverse address tree. This behavior has
also been applied to IPv6 addresses in their many shapes and
forms.
This change did two things, 1) root zone not implicitly added to
search list when looking up short name, 2) default domain appended
to short name if DEFNAMES and not DNSRCH.
Fix rt.cpan.org 18113
Minor error due to unapplied part of patch fixed.

Net::DNS::typesbyval() now confesses on undefined

Feature Implemented SPF (typecode 99).
The class completely inherits from Net::DNS::RR::TXT (the easiest
RR to implement ever).
Feature added rrsort() function.
Feature was requested by Eric Hall in rt.cpan.org 13392
This was a little tricky as I think that the sort functions are in
fact RR specific class attributes that should be accessed through
class methods. This is difficult to implement. I do think I found a
fairly clean manner. It does require a global variable in Net::DNS
to store the functions and some trickery when the sorting functions
are defined.
See Net::DNS and Net::DNS::RR documentation for details.
Defaults sorting functions are currently implemented in
SRV: default sort: low priority to high priority and for
same preference highest weight first.
weight: sort all RRs based on weight, highest first
priority: see default sort
MX: default sort: lowest preference first.

TCP fallback after V6 socket failure
Reworked Net::DNS::Base::Nameserver::send_tcp() to fallback to IPv4 when
possible. (change applied to SVN Revision 538).
Feature Cleanup duplicated code
axfr_send() and send_tcp() contained some duplicated code. I merged
this in one "helper" method _create_tcp_socket()
Fix AXFR persistent sockets colliding with query sockets.
I think that using the same persistent sockets for AXFR and
'ordinary' queries could lead to race conditions. Better safe than
sorry. For axfrs we create a different set of persistent sockets.
Note that this prevents performing a SOA query first and then using
the same socket for the zone transfer itself(in Net::DNS these are
different code paths). This behavior of SOA and transfer on the
same socket-- seems to be suggested by 1035 section 4.2.2:
"In particular, the server should allow the SOA and AXFR request
sequence (which begins a refresh operation) to be made on a
single connection."
Obviously, on the client side this behavior is not mandatory.
Fix rt.cpan.org 17596
The fixes and features above also fixed the timeout problem reported by
Paul Hoffman
Profiling
It turned out that each time we were calling

Using Net-DNS 0.53 on Win XP, it is unable to retrieve the
nameservers when the IP address of the interface is assigned by

RRSIGs verify and create failed for a number of RR types. The
error message showed something like:
Can't call method "dn_comp" on an undefined value
This was caused by an omission in the _canonicalRdata() method
in Net::DNS::RR that was inherited by all failing RR types.
Code was added to t/05-rr.t that will test signature creation
if Net::DNS::SEC is available and can be loaded.
Feature async nameserver behaviour.
In rt.cpan.org 14622 Robert Stone suggested:
The fact that it needs to take over the main running thread
limits its audience. Since many daemon programs are already
driven by a top level select loop, it seems useful to provide an
API for the user to integrate Net::DNS::Nameserver processing to
their own select loop.
He also supplied example code for which he is hereby acknowledged.
The patch was not used because simultaneously Robert Martin-Legène
supplied a patch to Nameservers.pm that allowed the same async
functionality through the use of loop_once method. Robert M-L's
code also carefully manages the TCP sockets, so that they can
deal with AXFRs.
Robert S. has been so kind to review Robert M-L's code and is hereby
kindly acknowledged.
NB. Since the code may be subject to change the documentation of the
loop_once method has been commented out.

Fix rt.cpan.org 13184:
Removed a 'stale' debug line (oops). A "stale" debug line may
cause clutter in log files which may cause false positives on log
analysis tools. Harmful enough to warrant a quick patch.
*** 0.50 June 8, 2005
No changes with respect to 0.49_03.
*** 0.49_03 June 1, 2005 (Version 0.50 release candidate 3)
Fix:
Concatenation of scalars caused modification of data because of
Perl's habit to treat scalars as utf characters instead of bytes.
Inserted use bytes pragma throughout the code base. DNS is done
in octets.
Feature:
Added "ignqrid" as an attribute to the Resolver.
use as:
ok (my $res=Net::DNS::Resolver->new(nameservers => ['127.0.0.1'],
port => 5354,
recurse => 0,
igntc => 1,
ignqrid => 1,
),
When the attribute is set to a non-zero value replies with the
qr bit clear and replies with non-matching query ids are
happily accepted. This opens the possibility to accept spoofed
answers. YOU CAN BURN YOURSELF WITH THIS FEATURE.
It is set to 0 per default and remains, except for this changes file
an undocumented feature.
*** 0.49_02 May 28, 2005 (Version 0.50 release candidate 2)
Fix: Smoking Gun tests for non-cygwin Win32.
Makefile.PL failed to produce a proper Makefile under win32.
(e.g. www,nntp.perl.org/group/perl.cpan.testers/210570)
I worked around that by moving the library into the base
directory of the distribution as the "subdir" section
seemed to be all funny.
Fix: rt.cpan.org#11931 (the off-topic part)
Sidney Markowitz spotted an awkward condition that rarely happens but is
significant enough to be dealt with.
In the send_udp method there are two loops: one over the nameservers
and one that waits for the sockets to come forward with data.
That second loop will sometimes timeout and then be entered with a
repeated query to the same nameserver. It occasionally happens that the
old packet arrives on the socket. That packet is discarded but the
loop does not return to the loop to wait for the remainder of the
timeout period for an answer on the second query, that may still arrive.
This has now been fixed.
Thanks to Sidney for the assessment of the problem and the fix.
*** 0.49_01 (Version 0.50 release candidate 1)
Fix: Makefile.PL: Minor tweak to recognize Mac OS X 10.4 not so relevant
since netdnslib is distributed with the code.
Feature: Calling the Net::DNS::Resolver::dnssec method with a non-zero
argument will set the udppacketsize to 2048. The method will
also carp a warning if you pass a non-zero argument when
Net::DNS::SEC is not installed.
Feature: IPv6 transport support
IPv6 transport has been added to the resolver and to the
nameserver code.
To use IPv6 please make sure that you have IO::Socket::INET6 version
2.01 or later installed.
If IPv6 transport is available Net::DNS::Resolver::Recurse will make
use of it (picking randomly between IPv4 and IPv6 transport) use
the force_v4() method to only force IPv4.
Feature: Binary characters in labels
RFC 1035 3.1:
Domain names in messages are expressed in terms of a sequence of
labels. Each label is represented as a one octet length field
followed by that number of octets. Since every domain name ends
with the null label of the root, a domain name is terminated by a
length byte of zero. The high order two bits of every length octet
must be zero, and the remaining six bits of the length field limit
the label to 63 octets or less.
Unfortunately dname attributes are stored strings throughout
Net::DNS. (With hindsight dnames should have had their own class
in which one could have preserved the wire format.).
To be able to represent all octets that are allowed in domain
names I took the approach to use the "presentation format" for
the attributes. This presentation format is defined in RFC 1035
5.1.
I added code to parse presentation format domain names that has
escaped data such as \ddd and \X (where X is not a number) to
wireformat and vice verse. In the conversion from wire format to
presentation format the characters that have special meaning in a
zone file are escaped (so that they can be cut-n-pasted without
pain).
These are " (0x22), $ (0x24), (0x28), ) (0x29), . (0x2e) , ;
(0x3b), @ (ox40) and \ (0x5c). The number between brackets
representing the ascii code in hex.
Note that wherever a name occurs as a string in Net::DNS it is
now in presentation format.
For those that dealt with 'hostnames' (subset of all possible
domain names) this will be a completely transparent change.
Details:
I added netdnslib which contains Net::DNS's own dn_expand. Its
implemented in C and the source is a hodgepodge of Berkeley based
code and snippets from ISC's bind9 distribution. The behavior, in
terms of which chars are escaped, is similar to bind9.
There are some functions added to DNS.pm that do conversion from
presentation and wire format and back. They should only be used
internally (although they live in EXPORT_OK.)
For esoteric test cases see t/11-escapedchars.t.
Fix: rt.cpan.org #11931
Applied the patch suggested by "Sidney". It is a practical workaround
that may not be portable to all versions of the OS from Redmond. See
the ticket for details.
*** 0.49 March 29, 2005
No changes wrt 0.48_03.
*** 0.48_03 March 22, 2005 (Version 0.49 release candidate 3)
Fix: Only remove leading zeros in the regular expressions for typesbyval
and classbyval methods. (patch by Ronald v.d. Pol)
Fix: Properly return an empty array in the authority, additional and answer
methods (patch by Ronald v.d. Pol)
Fix: rt.cpan.org #11930
Incorrect searchlist duplication removal in Net::DNS::Resolver::Win32
Patch courtesy Risto Kankkunen.
Problem: rt.cpan.org #11931
Win32.pm used the DNSRegisteredAdapters registry key to determine which
local forwarders to send queries to. This is arguably the wrong key as it
is used to identify the server which to send dynamic updates to.
A real fix for determining the set of nameservers to query has not been
implemented. For details see
https://rt.cpan.org/Ticket/Display.html?id=11931
*** 0.48_02 March 14, 2005 (Version 0.49 release candidate 2)
Fix: Bug report by Bernhard Schmidt (concerning a bug on the IPv6 branch).
The bug caused dname compression to fail and to create
compression pointers causing loops.
*** 0.48_01 March 7, 2005 (Version 0.49 release candidate 1)
Fix: rt.cpan.org #8882
No redundant lookups on SERVFAIL response
and #6149
Does not search multiple DNS servers
Net::DNS::Resolver will now use the other nameservers in the
list if the RCODE of the answer is not NOERROR (0) or NXDOMAIN
(3). When send() exhausted the last nameserver from the it will
return the answer that was received from the last nameserver
that responded with an RCODE.
The errorstring will be set to "RCODE: <rcode from last packet>"
Fix: rt.cpan.org #8803
TXT records don't work with semicolons
Since we are expecting "zonefile" presentation at input
a comment will need to be escaped ( \; ).
It could be argued that this is a to strict interpretation of
1035 section 5.1.
While working on this I discovered there are more problems with
TXT RRs. Eg; 0100 is a perfectly legal character string that
should be represented as "\000" in a zonefile. Net::DNS does
pass character strings with "non-ASCII" chars from the wire
to the char_str_lst array but the print functions do not
properly escape them when printing.
Properly dealing with zonefile presentation format and binary
data is still to be done.
Fix: rt.cpan.org Ticket #8483
eval tests for DNS::RR::SIG fail when using a die handler
(Thanks Sebastiaan Hoogeveen)
Patch applied.
Fix: rt.cpan.org: Ticket #8608
Net::DNS::Packet->data makes incorrect assumptions
Implemented the "pop" method for the question.
Since having a qcount that is not 1 is somewhat rare (it appears
in TCP AXFR streams) the ability to pop the answer from a question
has not been documented in the "pod"
Also fixed the incorrect assumption.
(Thanks Bruce Campbell.)
Fix: Ticket #11106
Incorrect instructions in README
Corrected in the README and in Makefile.PL
Olaf Kolkman took over maintenance responsibility from Chris
Reinhardt. This involved importing the code into another subversion
repository. I made sure the numbers jumped, but I did not have access
to the "original" subversion repository so I lost some of the history.
*** 0.48 Aug 12, 2004
Net::DNS is now stored in a subversion repository, replacing cvs.
As such the submodule version numbers have taken another big jump.
Luckily those numbers don't matter as long as they work.
Fixed a bug with Unknown RR types that broke zone signing [Olaf].
Added callback support to Net::DNS::Resolver::Recurse. The
demo/trace_dns.pl script demonstrates this.
Added a note regarding answers with an empty answer section to the
Net::DNS::Resolver::search() and Net::DNS::Resolver::query()
documentation.
The copyright notice for Net::DNS::RR::SSHFP was incorrect. That file
is Copyright (c) 2004 RIPE NCC, Olaf Kolkman.
*** 0.47_01 May 6, 2004
** NOTICE **
RR subclasses no longer pull in parts of Net::DNS; Net::DNS is assumed
to be up and running when the subclass is compiled. If you were using a
RR subclass directly, this may break your code. It was never documented
that you could use them directly however, so hopefully you never did...
Fixed bug where SRV records with a priority of 0 did not function
correctly. CPAN #6214
Calls to various constants where using the &NAME syntax, which is not
inlined. Changed to NAME().
Added SSHFP support. [Olaf]
CERT fixes. [Olaf]
*** 0.47 April 1, 2004
safe_push() is back in Net::DNS::Packet, due to the excellent debate
skills of Luis E Munoz. However, the name safe_push() is deprecated,
use the new name unique_push() instead.
Fixed a bug in Net::DNS::Nameserver which caused the class to build
packets incorrectly in some cases. [Ask Bjorn Hansen]
Error message cleanups in Net::DNS::typesbyname()
and Net::DNS::typesbyval() [Ask Bjorn Hansen]
Net::DNS::RR::new_from_hash() now works with unknown RR types [Olaf].
*** 0.46 February 21, 2004
IPv6 reverse lookups can now be done with Net::DNS::Resolver::search(),
as well as with query().
Hostnames can now be used in the 'nameservers' argument to
Net::DNS::Resolver->new()
*** 0.45_01 February 9, 2004
Net::DNS now uses UDP on windows.
Removed Net::DNS::Select from the package. IO::Select appears to work
on windows just fine.
Fixed a bug that caused MXes with a preference of 0 to function
incorrectly, reported by Dick Franks.
Net::DNS had a few problems running under taint mode, especially under
cygwin. These issues have been fixed. More issues with taint mode may
lie undiscovered.
Applied Matthew Darwin's patch added support for IPv6 reverse lookups to
Net::DNS::Resolver::query.
*** 0.45 January 8, 2004
No changes from 0.44_02.
** 0.44_02 January 3, 2004
The XS detection code was broken. We actually use the XS bits now.
Major cleanups/optimizations of the various RR subclasses. This release
of Net::DNS is over twice as fast at parsing dns packets as 0.44.
** NOTICE **
$rr->rdatastr no longer returns '; no data' if the RR record has no
data. This happens in $rr->string now.
Net::DNS::Packet::safe_push() no longer exists. The method is now only
available from Net::DNS::Update objects.
** 0.44_01 January 3, 2004
Net::DNS::RR objects were not playing nice with Storable, this caused
the axfr demo script to fail. Thanks to Joe Dial for the report.
** NOTICE **
This may cause RR objects that are already serialize to not deserialize
correctly.
Reply handlers in Net::DNS::Nameserver are now passed the query object.
Fixed a nasty bug in Nameserver.pm related to the qr bit. As Olaf
explained:
Replies are sent if the query has its "qr" bit set. The "qr" bit is an
indication that the packet is sent as a response to a query. Since
there are more implementations that suffer from this bug one can cause
all kinds of nasty ping-pong loops by spoofing the initial packet or
have an infinite query loop by spoofing a query from the localhost:53
address.
Various Win32/Cygwin cleanups from Sidney Markowitz.
*** 0.44 December 12, 2003
The Wrath of CPAN Release.
CPAN.pm doesn't understand the nature of revision numbers. 1.10 is
newer than 1.9; but CPAN.pm treats them as floats. This is bad.
All the internal version numbers in Net::DNS have been bumped to
2.100 in order to fix this.
No actual code changes in this release.
*** 0.43 December 11, 2003
Added warning of deprecation of Net::DNS::Packet::safe_push. This will
move into Net::DNS::Update, as Net::DNS::Update is now a proper subclass
of Net::DNS::Packet.
** 0.42_02 December 11, 2003
Fixed a long standing bug with zone transfers in the "many-answers" format.
CPAN #1903.
Added the '--online-tests' flag to Makefile.PL. This activates the online
tests without asking the user interactively. "--no-online-tests" turns
the tests off.
Cleaned up Makefile.PL a little. The "--pm" flag is now deprecated, use
"--no-xs" instead.
Added support for unknown RR types (rfc3597). Note for developers: the
typesbyname, typesbyval, classesbyname and classesbyval hashes should
not be used directly, use the same named wrapper functions
instead. [Olaf Kolkman]
Added two hashes for administrative use; they store which types are
qtypes and metatypes (rfc2929). [Olaf Kolkman]
** 0.42_01 November 30, 2003
Major work to get Net::DNS functioning properly on Cygwin by Sidney
Markowitz.
Fixed a bug in Net::DNS::Nameserver's error handling. CPAN #4195
*** 0.42 October 26, 2003
Fixed compilation problems on panther (Mac OS 10.3).
Fixed a bug in Net::DNS::Resolver::Recurse which allowed an endless
loop to arise in certain situations. (cpan #3969, patch
by Rob Brown)
Applied Mike Mitchell's patch implementing a persistent UDP socket.
See the Net::DNS::Resolver documentation for details.
*** 0.41 October 3, 2003
Added some documentation about modifying the behavior of Net::DNS::Resolver.
** 0.40_01 September 26, 2003
Fixed some uninitialized value warnings when running under windows.
Fixed a bug in the test suite that caused 00-version.t to fail with
certain versions of ExtUtils::MakeMaker. Thanks to David James, Jos
Boumans and others for reporting it.
Reply handlers in Net::DNS::Nameserver are now passed the peerhost.
(Assen Totin <assen@online.bg>)
Reply handlers in Net::DNS::Nameserver can now tweak the header bits
that the nameserver returns. [Olaf]
The AD header bit is now documented, and twiddlable. [Olaf]
The change log has been trimmed, entries for versions older than 0.21
have been removed.
** NOTICE **
Net::DNS::Resolver::axfr_old() has been removed from the package.
An exception will be thrown if you attempt to use this method. Use
axfr() or axfr_start() instead.
*** 0.40 September 1, 2003
Various POD tweaks.
** 0.39_02 August 28, 2003
Net-DNS-SEC updates, seems that IETF has been busy redefining DNSSEC.
[Olaf]
Added version to all the modules in the distribution.
** 0.39_01 August 12 2003
Added a META.yaml. The crystal ball says an upgrade to Module::Install may
be coming soon.
Changed how the versions of the various submodules were set. The CPAN
indexer cannot execute "$VERSION = $Net::DNS::VERSION". The single line
with the $VERSION assignment is pulled out of the file and eval'ed; at
that time, Net::DNS is not loaded. The submodules now pull their version
numbers out of CVS.
*** 0.39 August 7 2003
Fixed a bug on Win32 where some machines separated lists with commas,
not whitespace. Thanks to Jim White for pointing it out.
** 0.38_02 July 29 2003
Reworked the POD for Net::DNS::Resolver.
When parsing resolver configuration files, IPv6 addresses are now skipped,
as Net::DNS does not yet have IPv6 support.
** 0.38_01 Jun 22 2003
Broke Net::DNS::Resolver into separate classes. UNIX and Win32
classes are currently implemented. Many of the globals in
Net::DNS::Resolver no longer exist. They were never documented
so you never used them.... right?
Options to Net::DNS::Resolver->new() are now supported, including
using your own configuration file. See the Net::DNS::Resolver man
page for details.
Tweaked Net::DNS::RR::TXT to fail more gracefully when the quotes
in the data section are not balanced.
Add more tests (of course).
Moved next_id() from Resolver.pm to Header.pm (which is where it is
used).
Net::DNS::Select now uses $^O directly, this means that the second
argument to Net::DNS::Select::new() (the OS) is now ignored.
*** 0.38 Jun 5 2003
Various buglets fixed in the new Makefile.PL.
Use Dynaloader instead of XSLoader. Turns out that XSLoader is only
in more recent perls.
Added deprecation warning to Net::DNS::Resolver::axfr_old().
HP-UX fixes [cpan #2710], I don't have the name of the reporter/patcher.
*** 0.37 May 28 2003
Renamed the test C file to compile.c, test.c was confusing the 'make test'
target.
*** 0.36 May 28 2003
Removed Rob Brown's RPM stuff. Something odd happened in the 0.35 tarball
and at the moment I don't have the time to investigate.
*** 0.35 May 26 2003
POD fixes, added tests for POD.
*** 0.34_03 May 22 2003
Reworked Makefile.PL to try and detect if you have a working C compiler.
Added '--pm' and '--xs' command line options to Makefile.PL
Fixed linking problem on linux.
Tie::DNSHash removed from the package, see Tie::DNS from CPAN for a more
complete implementation of a DNS hash.
*** 0.34_02 May 21 2003
Net::DNS::Packet::dn_expand is now implemented using the function of the
same name from libresolv. This method of decompressing names is around
twice as fast as the perl implementation.
Applied Jan Dubois's patch to fix nameserver lookup on Windows 2000/95/98/ME.
*** 0.34 6 Mar 2003
Applied David Carmean's patch for handling more than one string in a
TXT RR's RDATA section.
Applied Net::DNS::Resolver::Recurse bug fixes from Rob Brown.
Added check of the answer's rcode in Net::DNS::Resolver::axfr_next().
Applied Kenneth Olving <kenneth.olving@eoncompany.com> Windows changes.
Applied patch from Dan Sully (daniel@electricrain.com) allowing multiple
questions to be part of a DNS packet.
*** 0.33 8 Jan 2003
Fixed 00-load.t to skip the Net::DNS::SEC modules. The test suite
should now pass if you have Net::DNS::SEC installed.
Fixed the regular expression in RR.pm to comply with the RFCs, turns
out we were _too_ paranoid. [Olaf]
*** 0.32 5 Jan 2003
Various cleanups for perl 5.004. Thanks to nathan@anderson-net.com
([cpan #1847])
Applied Olaf's SIG patch (thanks as always).
Win32 now looks at the environment variables when building the
configuration defaults. Thanks to net-dns-bug@oak-wood.co.uk
(That's the only name I have... [cpan #1819])
Added Rob Brown's Net::DNS::Resolver::Recurse module.
*** 0.31 17 Nov 2002
Applied Olaf's patch for an initialization bug in OPT.pm
Applied Rob Brown's patch for udp timeouts.
Added stuff from Rob Brown for making RPM creation easier.
Fixed a typo in FAQ.pod that was making apropos and whatis
grumpy. Thanks to Florian Hinzmann for pointing it out and a patch.
*** 0.30 7 Nov 2002
Applied Andrew Tridgell's (tridge@samba.org) patch for TKEY support.
Added Net::DNS::Packet->safe_push() to allow for automatically
checking for duplicate RRs being pushed into a packet. Inspired by Luis
Munoz.
Added more tests.
*** 0.29 2 Oct 2002
Fixed $_ from creeping out of scope in Resolver.pm. Thanks to
Ilya Martynov for finding the problem and the patch to fix it.
Fixed divide by zero bug there is no usable network interface(s).
Thanks to twilliams@tfcci.com, misiek@pld.ORG.PL (and one other
person that I can't seem to find the address of) for reports.
*** 0.28 20 Aug 2002
Fixed a bug in the new AUTOLOAD routines that made it impossible to set
attributes to '0'.
Fixed a bug in the RR patch that broke many updates.
*** 0.27 15 Aug 2002
Added (untested) support for perl 5.004.
We now allow whitespace at the beginning of a RR.
Fixed an issue that gave Net::DNS::SEC problems, %Net::DNS::RR::RR is now
in a scope that the Net::DNS::SEC hook can see it from.
Fixed SRV records.
Fixed debug message in Net::DNS::Resolver::bgread().
*** 0.26 5 Aug 2002
Fixed various bugs in the test suite.
Fixed warning in Net::DNS::RR::AUTOLOAD with perl 5.005.
