squid-deb-proxy should advertise and use IPv6 addresses

Thanks for the branch!

When testing this on my quantal box without any special configuration for ipv6 I get:
..
sudo apt-get update
[sudo] password for egon:
Ign https://private-ppa.launchpad.net precise InRelease
Ign https://private-ppa.launchpad.net precise InRelease
Ign http://ppa.launchpad.net precise InRelease
Err http://ppa.launchpad.net precise Release.gpg
  Something wicked happened resolving 'fe80::f094:52ff:fedc:e1bf:8000' (-9 - Address family for hostname not supported)
...

I look what might cause this now.

Also happens with fully updated quantal.

I have identified the issue here. apt is using a form of the getaddinfo which refuses to use addresses where we do not have a public address in that address family. The branch has been updated to include the same checks. Please test :)

This bug was fixed in the package squid-deb-proxy - 0.6.4

  [ Andy Whitcroft ]
  * squid-deb-proxy: advertise on IPv6 (LP: #1021298)
   - add IPv6 stanza to avahi configuration
   - add IPv6 link local addresses to default acls
  * squid-dev-proxy-client: support IPv6 addressing when offered under avahi
   - switch to python script to allow validation of the addresses against
     the public address families we have on our interfaces (uses the same
     algorithm used in apt to avoid "something wierd" errors)
   - look for IPv6 then IPv4 addresses in avahi browse responses
   - stop using the incoming interface specifier to imply address type
     use address form itself
   - format IPv6 addresses using the http://[address]:port/ form
