Queue_size not passed on topic subscribe

[smamessier]

On topic subscribe, queue_size is simply ignored. On the Websocket server side however, it is read as "msg.queue_length". So adding this line

queue_length: this.queue_size

should fix it.

Around line 1150 in Roslib.js

      if (this.subscribeId) { return; }
      this.ros.on(this.name, this._messageCallback);
      this.subscribeId = 'subscribe:' + this.name + ':' + (++this.ros.idCounter);
      this.ros.callOnConnection({
        op: 'subscribe',
        id: this.subscribeId,
        type: this.messageType,
        topic: this.name,
        compression: this.compression,
        throttle_rate: this.throttle_rate,
        queue_length: this.queue_size /* Added */
      });
    };
