[New-bugs-announce] [issue19012] liburl2: bad proxy configuration throws "getaddrinfo" error

[Sjoerd]

New submission from Sjoerd:

I'm sorry for providing very little information, but I don't have the system at hand anymore. Therefore I will try to reproduce what I know, hoping that you recognise the problem. If not, I will get back to the system and try to obtain the necessary information.

Calling liburl2.openurl('http://www.google.com') gave me an getaddrinfo error. Therefore, I checked my DNS configuration, which seemed okay and I issued a socket.getaddrinfo('www.google.com'), which correctly returned an IP address. Finally, I found out that I had an old, non-existing (?) proxy configuration in the Windows registry (that indeed turned up when calling liburl2.getproxies()). Removing the proxy configuration from my Windows registry solved the problem.

Is it preliminary to conclude that the getaddrinfo error may actually mean several things (not only a simple getaddrinfo problem)? If so, I suggest that the error message be broadened ("DNS lookup or proxy problem"), because it took me several hours to find the proxy problem.
