Hi guys, So, now that GCD sources are supported (go Ernie!), I just thought I'd play with a simple echo server example in MacRuby: require 'socket' q = Dispatch::Queue.concurrent m = Dispatch::Queue.main hostname = "localhost" port = 25000 s = TCPServer.open(hostname, port) src = Dispatch::Source.new(Dispatch::Source::READ, s, 0, q) { |src| client = s.accept # XXX Would like to actually get this from src, rather than grabbing the server socket object directly client.puts(Time.now.ctime) client.puts "Closing down, Bunkie!" client.close } m.run The line with the XXX is the issue I'm trying to figure out. If I look at src.handle or src.data, I end up getting an integer which looks like a fd, not the original TCPSocket instance I passed in, which means I can't call the accept method on it. Is there some secret to getting at the original handle? Thanks! - Jordan
