Subject: wrong split on Cygwin
On Cygwin the list of nameservers can be comma or space separated.

Could you paste a sample output? Also, this should have an accompanying test.

Can you support that assertion by pointing at some documentation? Where did the comma-separated list originate?

No, that's just what I got back from the call. Show quoted text
> Where did the comma-separated list originate?
I don't really know, but I believe that it's from DHCP. It only happens on a corporate network so far.

The string I got back was simply two numerical IPv4 addresses separated by a comma, which then failed to resolve of course. The DNS servers on that network have no names and I believe that setup comes in via DHCPv4, but I can't say for sure.

DNS servers never have names.

There seems to be no good definition of registry file syntax. From the scraps I dredged up, it seems that it may not even be consistent across all Windows versions. I note that the search list has been split on either space or commas since cygwin support appeared in 0.43 (2003). On the optimistic assumption that this is more widely applicable, I have applied that fix to all the splits. A dev release Net::DNS 1.00_01 was uploaded to CPAN this morning which should overcome the problem.

Well, it's supposed to be space separated but apaprently not always. I've looked it up in the registry again on my computer at work and currently it has a space as separator, but I'm both on a different computer and network in the meantime. Show quoted text

I can't tell how it would work with a comma since my build system has only a single entry in DhcpNameServer, but I built and tested 1.00_01 just fine on perl-5.22.0-RC2 on Cygwin. Will this become a normal release shortly? I'll build a new Perl for Cygwin plus all the distributions for Cygwin some time next week.

A little too late for your build, but the 1.01 release will follow very shortly now (likely within 1 week).

Still in time, thank you very much. Since there are literally hundreds of CPAN packages to update or rebuild and not all of them are maintained by myself, this takes quite a while.
