Dear Team of Net::DNS,
there is a Bug in Net/DNS/Resolver/Base.pm, that can be fixed using the
patch attached to this email.
Version of Net-DNS used: 0.78
Issue: The constructor "sub new" does not properly copy the $defaults
hash reference, before making changes, therefore independent
Net::DNS::Resolver objects affect each other.
The fix is to simply apply a deep copy on the $defaults hash ref.
Example code triggering the bug:
# ------------------------------------------------------------------
use Net::DNS;
my $resolver = new Net::DNS::Resolver (
nameservers => ['some-non-existing-ns.'],
recurse => 0,
);
my $resolver2 = new Net::DNS::Resolver (
nameservers => ['ns1.hexonet.net.'],
recurse => 0,
debug => 1
);
$resolver2->query("www.hexonet.net.");
# ------------------------------------------------------------------
$resolver2 does not work, as 'ns1.hexonet.net.' doesn't get resolved.
(because the $resolver constructor above overwrote the $defaults).
$resolver2 works however, when removing $resolver, or applying the patch.
Please let me know, if you need further infos. And thanks a lot for
maintaining Net::DNS + Net::DNS::SEC!
Best,
- jens
