[Yum-devel] urlgrabber and rrdns

[Johnny Hughes]

When using urlgrabber against an rrdns name, I am seeing that it picks 1
IP address from the list an overwhelming percentage of the time.

I have tested 2.9.6 and 2.9.7 urlgrabber and both exhibit this trait.

Using a simple script to grab a url from a webserver that is tied to a
rrdns with several names, 1 IP came up more than 95% of the time on
every test.

Pinging the the same rrdns list in a loop script ends up with the
distribution of IPs as you would expect ... nearly a 50-50 split for 2
IPs, a 1/3 split for 3 etc.

I think that the desired effect if you have more than 1 IP address
returned would be to take the first listed IP address ... or if that is
not possible, at least a random IP address from an RRDNS list.

I am not sure if this is a urlgrabber issue or whatever resolves the
URL's name in python, but I don't think it is the desired behavior.

Thanks,
Johnny Hughes
