client don't try reconnect

[2547409617]

hi,
I run ping pong example, first run server and then run client, all is ok.
I kill server, and run server again, client don't try reconnect.
I hope client will try reconnect if network is disconnect.

Remove reconnect=5 from the example.

Hi, I guess you're using Tcp or FramedTcp right? The way it works is how TCP works.

TCP does know about reconnections. Once the channel is closed by one side (i.e, when you kill the server), the connection is considered closed for the other endpoint. If you want a reconnection mechanism, you should implement this on top of Tcp by yourself. i.e, trying to connect again after some incremental period or similar.

The way I got around this is to have the handler instantiation and listener.for_each into a loop block, you can then handle reconnection logic on exit.

e.g. the below will just wait 5 seconds, then try to reconnect

loop {
  let (handler, listener) = node::split::<()>();

  let server = handler.network().connect(...)?;

  listener.for_each(move |event| match event {
    NodeEvent::Network(net_event) => match net_event {
      NetEvent::Disconnected(_endpoint) => {
        // do anything you want to do before exiting the listener...
        handler.stop();
      }
      _ => {}
    }
  });

  // at this point, the client has disconnected, so do anything you want to do such as waiting a few seconds before reconnecting...
  std::thread::sleep(std::time::Duration::from_secs(5));
}

That way you can easily implement your own re-connection logic (exponential fallback, max # of retries etc.)

Thanks for your solution!

In addition to the above answer, you can also use signals with a timer (send_with_timer) to create new connections inside the for_each and avoid disconnecting the listener.
