The way to determine tcp/unix may be not so right.

[ckrissun]

Take a look at this:

  n := "tcp"
  if strings.Contains(cfg.Addr, "/") {
      n = "unix"
  }

When cfg.Addr equals to ./server.sock, everything is ok. But what happen when cfg.Addr is server.sock? Absolutely, something goes wrong.

I notice that, when net.ResolveTCPAddr returns an error, then we can say cfg.Addr is a unix address

  n := "tcp"
  if _, err := net.ResolveTCPAddr("tcp", cfg.Addr); err != nil {
      n = "unix"
  }

Thanks!

I see some other apps use above way to select tcp network and don't think it is a big problem because the config address is set by yourself, if you set invalid, dial will be error, you will be responsible for your configuration.

Thanks you!

Yeah, I see. It's really the user's responsibility to do that. Maybe I just want to make everything right as possible as i can. Thank you.
