AutobahnJS Chrome Close

[Jason Yates]

Hi,

I'm using AutobahnJS 0.8.2 with the below connection code. This works perfectly in FireFox and in Chrome for the most-part, however when we loose connection to the WS server for whatever reason, FireFox seems to trigger the error function and logs an error to console and auto-reconnects but Chrome does nothing. It simply silently drops the connect to the WS server and dies.

   // Start a connection

    var conn = new ab.connect('wss://127.0.0.1:443', function(session) {

        // Log an error

        conn.onerror = function(e) {

            console.log('WebSocket error: ' + e.data);

        };

        // Subscribe to a topic

        session.subscribe('topic', function(topic, data) {

            

        });

    }, function (code, reason, detail) {

        // Log to console

        console.log('WebSocket error: ' + reason);

    }, {

        'skipSubprotocolCheck': true,

        'maxRetries': 60,

        'retryDelay': 1000

    });

I need to get the same behaviour in chrome (i.e the auto-reconnect) as I have in firefox. Any ideas?

Thanks

Hi,

Is anybody able to provide any suggestions? I've done as much testing as I can and Chrome simply doesn't seem to notice that the socket connection has gone away.

Thanks

Things you can try:

1) enable max logging and compare logs FF/Chrome. maybe it reveals
something.

ab.debug(true, true, true);

https://github.com/tavendo/AutobahnJS/blob/wamp1/autobahn/autobahn.js#L264


2) get the non-minimized version, and modify this line

https://github.com/tavendo/AutobahnJS/blob/wamp1/autobahn/autobahn.js#L611

adding console.log there.

probably recent chrome versions changed their behavior.

thing is: the WS API has two hooks

socket.onclose
socket.onerror

and browser beh. might differ


3) guess you are aware that you are using an old AutobahnJS (WAMP1). we
are no longer using this ourselfes. what I can say is: the current
version of Autobahn (0.9.3) _does_ automatically reconnect, on FF and
Chrome, and also via WSS

and it only hooks into socket.onclose:

https://github.com/tavendo/AutobahnJS/blob/master/package/lib/connection.js#L261

which means: 2) isn't a convincing explanation.


4) before loosing even more time, you might try AutobahnJS current
against a WAMP2 server in your network/browser env.

even if that (WAMP2) is not what you want, it might help us track down
whats going on. since, as mentioned, this (AB current) definitely works
with automatic reconnects on chrome.
