Hello...
Please CC me on replies as I am not subscribed, thank you.
Resending, because the archives show the message mangled... Sorry, if you
receive this twice.
I am the co-maintainer of the Debian package of dnspython. A user forwarded me
the attached patch (just rediffed against 1.3.5, as the current Debian
version is 1.3.4).
It seems that in dns/resolver.py in function query() the nameservers are
queried, but even in the event of a useful response dnspython uses the "don't
pound the nameservers" wait.
The attached patch fixes this by breaking out of the while loop, if response
"is not None" before executing the wait.
I am not quite sure, whether this actually is the right way to fix the
problem, or if there actually is a problem, but the patch makes sense to me,
so I forward it here.
Patrick
