How to catch nanomsg timeout ? about node-nanomsg HOT 6 CLOSED

hi @GrimDev, sndtimeo and rcvtimeo aren't going to emit either of those events.

All they are designed to do is delay send or recv operations on the socket.

Can you paste your code so we can take a look?

from node-nanomsg.

Thanx for your quick reply.

See my code bellow (coffee script)

// I create my socket in pair
console.log "init"
@socket = nano.socket("pair")
addr = "tcp://0.0.0.0:1665"
sock = @socket.bind addr

// Set snttimeo and rcvtimeo at 100
@socket.sndtimeo(100)
@socket.rcvtimeo(100)

// I do a ping each 30 sec
ping = =>
version = @protocolVersion
msgType = 20
message = 0
phone = 0
message = [version,msgType,message,param].join ":"
@socket.send message

setInterval ping, 30000

// Now I want to execute function when timeout occurs
@socket.on "I dont know what I can put here" , -> #my function

I tryed socket.on "error", "timeout", "survey-timeout", but didnt work.

Oh I'm sorry I can't understand coffee, can u please translate into JS!

Yes.

This is the translation

// Init socket
var addr, ping, sock, socket;
socket = nano.socket("pair");
addr = "tcp://0.0.0.0:1665";
sock = this.socket.bind(addr);

// Params
this.socket.sndtimeo(100);
this.socket.rcvtimeo(100);

// Ping function
ping = function() {
var message, msgType, phone, version;
version = _this.protocolVersion;
msgType = 20;
message = 0;
phone = 0;
message = [version, msgType, message, param].join(":");
return _this.socket.send(message);
}
setInterval(ping, 30000);

// Catch timeout
socket.on("timeout", function() {
console.log("Timeout catched !");
})

Timeout has a special meaning in JS that doesn't apply here.

maybe we should think about changing the language in the docs to "delay" to avoid that confusion in the future.

There's no timeout event that will fire here, it's just setting a silent delay on the socket I/O operation.

OK

I understood rcvtimeo and sndtimeo was the delay timeout, but I thought a timeout event is throw when it occurs.

I'll do a ping/pong to detect deconnections.

Thx for your replies.
