Version 0.51 has been released and is available from CPAN.

Version 0.50 contained a "stale" debug line that prints cruft to STDOUT. (See rt.cpan.org #13184). That cruft may end up in log files and trigger log file analyzers.

Bug reports are welcomed through rt.cpan.org.

Version 0.50 has been released and is available from CPAN.

Main differences between version 0.49 and 0.50 are:

• IPv6 transport for the Resolver and the Nameserver classes. This is provided that you have Socket6 and IO::Socket::INET6 installed.
• Binary label support for domain names.
• No dependency on the systems libresolv, which caused differences in behavior with respect to binary labels and caused all these compile bugs on Tiger. Net::DNS now commes with its own library, that currently only contains dn_expan().

Bug reports are welcomed through rt.cpan.org.

Version 0.49_03 has been released and is available from CPAN.

During development of some other code I ran into a hard to reproduce and system depended bug that was caused by Perl’s behavior to treat characters as unicode as soon as it thinks that is relevant. I introduced the "use bytes;" pragma throughout the code to cope with this.

Another minor modification is the ignqrid flag in Net::DNS::Resolver. In the default situation the Resolver will drop packets with the QR bit cleared (this is a good thing, see draft-arends-dnsext-qr-clarification) and if the ID on the response does not match that on the query, that helps protecting against spoofs. When ignqrid is set the packets with QR cleared or an ID mismatch are accepted. Use with care.

Unless critical bugs are found I will not touch this code and track the cpan testers page to see if the beast PASSes the test on a couple of platforms.

Talking about cpan testers, it is of great use as a troubleshooting tool for these pre-releases. Read Becoming a CPAN Tester with CPANPLUS and configure your system to send those reports.

Over the weekend I uploaded Net::DNS version 0.49_02 to CPAN.

This version contains a fix for a compile error on Win32 systems that showed up through the CPAN testers system.

This version also addresses the situation that when a resolver would have timed out on a first query but the answer on that first query would arrive during a retry the resolver would throw away that first packet (which is intended) and then not wait for the answer for the second query to appear. This is a significant effect in some environments. Thanks to Sidney Markovitz for the assessment of the problem and suggestions for a fix.

I have just uploaded Net::DNS version 0.49_01 to CPAN.

This is a release candidate for 0.50 and features IPv6 support, a number of tweaks for proper binary label support.

Net::DNS now come with its own c-library (which only contains dn_expand for now) and ends the need for relying on libresolv.a.

See the Changes file for details.

I have just released Net::DNS::SEC 0.12_01. This version fixes a few minor bugs, slightly changes the Net::DNS::SEC::Keyset->verify method and has its documentation updated to refer to RFC4033, 4034 and 4035.

Download the package from CPAN or from the download section of the site.

Net::DNS version 0.49 is available from CPAN.

There have not been changes between version 0.48_03 and this release.

For the changes since 0.48 see the Changes file.

If there is not a flood of bugs I will start moving the IPv6 code and the support for binary content on to the trunk and prepare for version 0.50 during the next few months.

I have just uploaded 0.48_3.

The most significant change is in Win32.pm where a bug has been caused by reading a wrong registry key. It is known that this code still has problems. For details see ticket 11931 in rt.cpan.org. The bottom line is that if we need to reliably find the list of nameservers we will need to do a call to a windows library. Since I failed to get Win32:API working with cygwin I figured that the important prerequisite to get a portable fix was missing and I stalled the ticket. I am open to suggestions and contributions.

Without feedback and new urgent bug-fixes the plan is track CPAN test to make sure nothing is broken release version 0.49.

I have just uploaded version 0.48_2 to CPAN.

Version 0.48_1 contained a bug causing wrong domain name pointers. The bug was spotted by Bernard Schmidt who found it in the IPv6 branch. The bug was painful enough to bump to 0.48_2.

If no new bugs are found I plan to release version 0.49 once I’ve seen sufficient positive CPAN Tests.

0.48_1

Version 0.48_1, a prerelease for 0.49, has been pushed to CPAN and should be available shortly.

This version contains a number of bug fixes. If the Perl Testers do not find any major flaws this package will be published as version 0.49
