Revision history for Net::DNS
=============================
*** 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 NO ERROR (0) or NAME
ERROR (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 error string 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 presentation format 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. e.g.; '0100' (a character string content represented in
hex) is a perfectly legal and should be represented as "\000" in
presentation format. 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.
Some tests with TXT RRs added to 07-misc.t
Properly dealing with zone file 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
Reinardt. 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::Recuse. 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 Monoz. 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' arguement 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
lay 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
avalible 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 presistant 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 twiddleable. [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 seperated 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 seperate 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 envirement 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 aropos 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 creaping 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 pat that broke many updates.
*** 0.27 15 Aug 2002
Added (untested) support for perl 5.004.
We now allow whitespace at the begining 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.
