I've noticed a potential bug and wanted to see if anyone else can replicate it, or has also seen it. When creating a socket with getaddrinfo, with the address family set to AFUNSPEC and the host set to localhost, the socket binds to IPv4 instead of IPv6. When using the FQD of the machine it binds to IPv6. I've tested the same code on two different machines, and the one running python 2.3.3 works as it should, but the python 2.3.4 doesn't.

Can you show the code fragment that you use? socket.getaddrinfo does never ever create sockets; only socket.socket does. So you apparently somehow use the results of getaddrinfo to create the socket. As getaddrinfo may return multiple results, you somehow need to select one of the results to create the socket, but you don't explain which result you use. A code snippet would answer the question.

Anyone seen this? Can you replicate the error? Any help would be appreciated. Oh yeah, I'm running on FC2 on the 2.3.4 machine and redhat 8 on the 2.3.3 machine.

I can imagine a code fragment where this happens, but I hardly can see an error here.

Regards, Martin
