Bug #113020 for Net-DNS: Resolve::Recurse Hangs

Mon Mar 14 17:04:45 2016 dwheeler [...] cpan.org - Ticket created

Subject:	Resolve::Recurse Hangs
Date:	Mon, 14 Mar 2016 14:04:29 -0700
To:	bug-net-dns [...] rt.cpan.org
From:	"David E. Wheeler" <dwheeler [...] cpan.org>

Noticed this when running tests: One some boxes, t/08-recurse.t hangs forever, sometimes after test 1, other times after test 7. Using Perl 5.20. Here’s a one-liner: perl -Ilib -MNet::DNS::Resolver::Recurse -E 'Net::DNS::Resolver::Recurse->new->query_dorecursion( "www.net-dns.org", "A" )' I can’t figure out what it’s problem is. It doesn’t *alway* hang, and on some boxes I have, it never hangs. But it does on my Mac (OS X 10.11.2 El Capitan) and on our CentOS 7 VMs. Is there some way to get that test to time out and skip if it times out?

I am unable to repeat your observation on my dev kit, and have a feeling that this may be another manifestation of RT#112860. Do any of your boxes fail reliably? Is there any correlation of the failing boxes with those exhibiting RT#112860? Have you the time and inclination to help get to the bottom of this?

Could be. Show quoted text

Yes. Show quoted text

I don’t think so. All of them exhibited RT-112860; only a subset exhibits RT-113020. Show quoted text

Sure. What do you need me to do? D

I guess we should focus on 112860. Show quoted text

Not sure yet, but I will think about it and cook a patch
