The Go programming language
c83b838641
added ReadFrom/WriteTo for packet protocols like UDP. simplified the net.Conn interface. added new net.PacketConn interface for packet protocols. implemented proper UDP listener. cleaned up LocalAddr/RemoteAddr methods - cache in netFD. threw away various unused methods. an interface change: introduced net.Addr as a network address interface, to avoid conversion of UDP host:port to string and back for every ReadFrom/WriteTo sequence. another interface change: since signature of Listener.Accept was changing anyway, dropped the middle return value, because it is available as c.RemoteAddr(). (the Accept signature predates the existence of that method.) Dial and Listen still accept strings, but the proto-specific versions DialTCP, ListenUDP, etc. take net.Addr instead. because the generic Dial didn't change and because no one calls Accept directly (only indirectly via the http server), very little code will be affected by these interface changes. design comments welcome.
