Maintenance Blog

Dear all,

We have a candidate for the 85th release of Net::DNS which will be version 1.08.

This release has a single new feature that enables registering a handler for UPDATE requests in custom name servers.

Makefile.PL will more actively try to detect ineffective install locations due to existing Net::DNS installs earlier in the search path, and will report more clearly about this specific situation.

Besides this, we’ve decided to finally drop support for Perl versions before 5.6. Supporting only 5.6 and later allowed for a major (early) spring-clean of all the pre-5.6 workarounds and outdated language features and makes the code base easier to read, understand and maintain.

For a complete overview see the Changes file.

Please review this candidate carefully. If no issues arise, the actual release will follow Monday the 20th of February 2017.

Dear all,

We have just released version 1.03 of Net::DNS::SEC.

This release has no core code changes whatsoever. It contains only an altered Makefile.PL that avoids problems with old MakeMaker and improved unit tests to get 100% coverage! and to address issues arising from incompatible versions of prerequisite.

For a complete list of changes and bugfixes see the CHANGES file.

We have a new release, version 1.06 of Net::DNS.

– Parsing of scoped IPv6 has been fixed when IO::Socket::IP is used (regression since 1.05).
– Interfering middle boxes will no longer be able to hang recursive lookups and interfere with unit tests.
– Linking of CNAMEs to its target address records with resolver->nameservers() will be done case insensitive.

This release also includes updated error reporting resulting from discussion and comments from the mailing list:

• axfr() in list context returns the complete zone if successful. If an error occurs, an empty list is returned with errorstring() indicating the reason.
• axfr() in scalar context returns an iterator if successful. If a connection failure occurs, undef is returned with errorstring() indicating the reason. The iterator will raise an exception if the transfer can not be completed.
• Resolver documentation has been clarified to make explicit that errorstring() is valid immediately after an error and meaningless otherwise.

We have a second candidate for the upcoming 1.06 bugfix release of Net::DNS. A list of bugfixes can be found in Changes.

This release candidate includes changes resulting from discussion and comments from the mailing list on error handling with zone transfers. Resulting in:

• axfr() in list context returns the complete zone if successful. If an error occurs, an empty list is returned with errorstring() indicating the reason.
• axfr() in scalar context returns an iterator if successful. If a connection failure occurs, undef is returned with errorstring() indicating the reason. The iterator will raise an exception if the transfer can not be completed.
• Resolver documentation has been clarified to make explicit that errorstring() is valid immediately after an error and meaningless otherwise.

In the process of reducing code complexity and improving code coverage of the unit tests, the value of errorstring() is with this release candidate *meaningless* when not consulted directly after failure, similar to the predefined perl variable $! (see perlvar). Testing successful zone transfer by testing errorstring() for a value that it was known to have before the transfer, will no longer work.

Please review this candidate carefully. In particular with respect to error handling. If now issues arise, the actual release will follow Friday the 27th of May.

We have a candidate for the upcoming 1.06 bugfix release of Net::DNS.

– Parsing of scoped IPv6 has been fixed when IO::Socket::IP is used (regression since 1.05).
– Interfering middle boxes will no longer be able to hang recursive lookups and interfere with unit tests.
– errorstring() results for non-errors has been restored (“regression” since 1.05)

Besides these bugfixes, this release
– has better TSIG error reporting
– has better Resolver.pm documentation
– and has great coverage results!

If no issues arise, the actual release will follow Monday the 25th of April 2016.

We have a new release, version 1.05 of Net::DNS.

This release deals with a few ticket from request tracker.

– TSIG algorithm names will be compared case insensitive again (bug since 1.02).
– Makefile.PL will issue a warning when an earlier version of Net::DNS (before 1.01) was installed on a different (architecture dependent) location.
– The asynchronous support functions (bgsend / bgread) now support transparent retry over TCP with truncated UDP packets.

Also support for the SMIMEA resource record was added.

We have a new release, version 1.04 of Net::DNS.

This is a emergency recovery and bugfix release.

The 1.03 release of Net::DNS addressed some longstanding request tracker issues (TCP and persistent sockets for bg(send|read|isreead)), but unfortunately in such a way that dependent modules broke.

This release has fixes to make those dependent modules work again without losing the aforementioned work.

To support us in this effort we have started to do regression testing of dependent modules ourselves, by running the dependent module’s test suite against a new Net::DNS. The results of these tests are put online here: https://www.net-dns.org/regression/.
