Bug 146321 – ruby gem_server failes with getnameinfo: ai_family not supported

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Roy Wright 2006-09-04 15:02:03 UTC]

If ruby-1.8.5 is compiled without IPV6, running gem_server will generate the following error:

2006-09-04 16:49:30] INFO  WEBrick 1.3.1
[2006-09-04 16:49:30] INFO  ruby 1.8.5 (2006-08-25) [i686-linux]
/usr/lib/ruby/1.8/webrick/utils.rb:63:in `getaddrinfo': getnameinfo: ai_family not supported (SocketError)
        from /usr/lib/ruby/1.8/webrick/utils.rb:63:in `create_listeners'
        from /usr/lib/ruby/1.8/webrick/server.rb:75:in `listen'
        from /usr/lib/ruby/1.8/webrick/server.rb:63:in `initialize'
        from /usr/lib/ruby/1.8/webrick/httpserver.rb:24:in `initialize'
        from /usr/bin/gem_server:351:in `new'
        from /usr/bin/gem_server:351

The cause is this line in /usr/lib/ruby/1.8/webrick/utils.rb:

      res = Socket::getaddrinfo(address, port,
                                Socket::AF_UNSPEC,   # address family
                                Socket::SOCK_STREAM, # socket type
                                0,                   # protocol
                                Socket::AI_PASSIVE)  # flag

The problem is the Socket::AF_UNSPEC which is apparently causing getaddrinfo to try some IPv6 processing.

What is needed is when -IPV6, to replace Socket::AF_UNSPEC with Socket::AF_INET to restrict getaddrinfo to IPv4:

      res = Socket::getaddrinfo(address, port,
                                Socket::AF_INET,   # address family
                                Socket::SOCK_STREAM, # socket type
                                0,                   # protocol
                                Socket::AI_PASSIVE)  # flag

Can you file a bug at the ruby bugs site so they can fix this directly in ruby?

I think the URL is  http://rubyforge.org/tracker/?func=add&group_id=426&atid=1698

Closed as UPSTREAM. I don't think we have time for this bug in the moment.
