Subject: "Helpful" DNS servers break t/head_ok.t (with patch)
Download (untitled) / with headers
text/plain 621b
DNS servers that return their own advertising host for an unknown host break t/head_ok.t. I just discovered Qwest doing this to me. I see there is a check, but the check isn't working. I think the problem is that a full URL is being passed to gethostbyname(), it will always fail. It should be just the domain name. Also its an obviously invalid domain as it contains a trailing dot. Finally, the domain tested at the top isn't the domain tested at the bottom. I removed the unnecessary BEGIN blocks and constant, it made working with the code complicated. If necessary, I can turn DNS breaking back on to verify.

Your patch had probs with not interpolating $NONEXISTENT, but I have fixed it. Also, it only skips one block, not the whole test.

It seems that is no longer honoring the bugtracker resource in META.yml. I'll poke them about it. -- If you want the truth to stand clear before you, never be for or against. The struggle between "for" and "against" is the mind's worst disease. -- Sent-ts'an
