Getty is a asynchronous network I/O library in golang. Getty is based on "ngo" whose author is sanbit(https://github.com/sanbit).
In getty there are two goroutines in one connection(session), one handle network read buffer tcp stream/udp packet/websocket package,

the other handle logic process and write response into network write buffer. If your logic process may take a long time, you should start a new logic process goroutine by yourself in codec.go:(Codec)OnMessage.

You can also handle heartbeat logic in codec.go:(Codec):OnCron. If you use tcp, you should send hearbeat package by yourself, and then invoke session.go:(Session)UpdateActive to update its active time. Please check whether the tcp session has been timeout or not in codec.go:(Codec)OnCron by session.go:(Session)GetActive.

Whatever if you use websocket, you do not need to care about hearbeat request/response because Getty do this task in session.go:(Session)handleLoop by sending/received websocket ping/pong frames. You just need to check whether the websocket session has been timeout or not in codec.go:(Codec)OnCron by session.go:(Session)GetActive.
