IPv6 support about rabbitmq-c HOT 5 CLOSED

Seems like this would be an easy feature to add. I will look into it.

from rabbitmq-c.

Note for myself when I get around to actually doing the work:

@bodgit - I've created a patch to support IPv6, but I have no way to test it (IPv6 is turned off at work, and my router at home doesn't support it either). If you have a broker running on a machine capable of IPv6, could you try building the code referenced in #26, and run one of the examples and connect over IPv6 and verify what I did was correct.

If it works I'll merge it.

I've just tried connecting with `amqp_consumer' and it seems to work with both a hostname and a literal IPv6 address.

It seems to prefer the IPv4 address first for a host that resolves to both address types (but that could be something to do with my client host), but if the IPv4 connect fails then it retries with the IPv6 address and succeeds.

Good to see it appears to work.

The code attempts to connect to the different endpoints in the order that getaddrinfo returns them in. The manpage for getaddrinfo says the ordering is defined in RFC 3484, and I'm not sure how to apply all the rules to understand why the IPv4 address gets tried before the IPv6 address.
