connection.isRetrying not working for me (sort of)

[Greg Fausak]

I have the javascript code:

var connection = new autobahn.Connection({

         url: '%s',

         realm: '%s'

      });

connection.onclose = function (session) {

    console.log('Session to database closed');

    if(connection.isRetrying == true) {

        document.getElementById("info").innerHTML = '<p>Autobahn Connection Closed (retrying)</p>';

    } else {

        document.getElementById("info").innerHTML = '<p>Autobahn Connection Closed (forever)</p>';

    };

};

I tried to debug this for a while.  I was just killing the router, which triggered the onclose. The problem I was seeing was my javascript was picking up connection.isRetrying == false.

It appears that when the connection first goes down, isRetrying is false.  Then, after the first retry, isRetrying is true. What is the proper way to determine if my connection will be retried?

Hi Greg,

try:

connection.onclose = function (details) {
   console.log(details.will_retry);
}

You can also (manually) stop automatic retrying by returning true from above handler.

Cheers,

Tobias,

I tried the following code:

connection.onclose = function (details) {

    console.log('will_retry ', details.will_retry);

...

Here is the console log for that message:

will_retry  undefined 

Maybe my autobahn.min.js file is old?

I get 'true', with version 0.9.5.

That's weird.

When I just log the value of 'details' I get 'lost', like details is just a string.

The source ...

         // fire app code handler
         //
         if (self.onclose) {
            var details = {
               reason: self._session_close_reason,
               message: self._session_close_message,
               retry_delay: next_retry.delay,
               retry_count: next_retry.count,
               will_retry: next_retry.will_retry
            };
            try {
               // Connection.onclose() allows to cancel any subsequent retry attempt
               var stop_retrying = self.onclose(reason, details);
            } catch (e) {
               log.debug("Exception raised from app code while firing Connection.onclose()", e);
            }
         }

 

So I had the function declared with one argument(details) instead of two (reason,details).

I just have:

connection.onclose = function (reason, details) {
  console.log(details.will_retry)
  console.log("Connection lost: " + reason);
}

[Greg Fausak]

that's what it was, my code:

connection.onclose = function (details) {

    console.log('will_retry ', details.will_retry);

did not declare the first argument.

thx,
