"Unspecified error" from _process

Question

"Unspecified error" from _process

Closed this issue 13 years ago · 8 comments

I've got a program working great in Firefox and Chrome but in Internet Explorer 8 on Windows XP, I get an "Unspecified Error" on line 3872 (of the uncompressed version). It seems that this._req is undefined? What am I missing?

Incidentally, how do I get JSJaC to NOT delay several seconds before sending messages?

Sorry, guess that's a hard one. You're not "missing" anything. I remember I had such an issue some years ago at one of my customers but unfortunately I can't remember exactly how we solved the issue. It was not an error with jsjac itself but somewhat about how and when all things are being initialized. Are you using the onload event to start using jsjac?

Incidentally, how do I get JSJaC to NOT delay several seconds before sending messages?

Is this also IE8 only or does it happen to you on any platform?

Found the problem. I was running my web application on www.lockaby.org but my HTTP-BIND path was on im.lockaby.org. This configuration apparently works with Firefox and Chrome but NOT Internet Explorer. I changed it to be on the same host in the same domain and now it works.

As for the delay, that happens on every platform. It sends the post eventually, but only after it hits the 30 second timeout. Is there a way to force the connection to flush its buffer?

No sorry, there's no such thing. There must be some problem with your setup still. JSJaC flushes it's queue every 100ms or such automatically (you can tweak this value by changing JSJAC_CHECKQUEUEINTERVAL).

Further information: jsjac will wait until the server sends something -- such as a presence notification -- then start a new connection where the first thing it does is send the message before it too closes. Then a third notification starts. So the timeline is like this:

client sends a message, nothing happens
long connection terminates because server pushes something to the client
new long connection started
client finally actually sends the message from step 1 and the long connection terminates again
new long connection
go to step 1

I'm skeptical that it is a configuration issue on my end because there were no problems when I was using strophe, but strophe but I didn't like strophe for reasons left unsaid.

This behavior has been reported to me several times but I haven't been able to ever reproduce it myself with jsjac. Funny thing is that I had this behavior with strophe some time ago.

Which version of jsjac are you using exactly? Please try setting the property 'timerval' when creating the JSJaCHttpBindingConnection like:

var con = JSJaCHttpBindingConnection({'httpbase': '/http-bind/', 'timerval': 1});

Also please show me exactly which arguments you're passing to the inherit method.

As properties of args to inherit() you must also set

polling
inactivity
requests

as returned by the initial response from the BOSH service.

So your code might look like this:

args = new Object();
args.username = username;
args.domain = domain;
args.resource = resource;
args.sid = '';
args.rid = parseInt();
args.polling = parseInt();
args.inactivity = parseInt();
args.requests = parseInt();
connection.inherit(args);

It may also be necessary to set the 'wait' attribute as well.

Answer 8 · 2011-08-30T23:00:33.000Z

Sure enough, setting those three properties made it work the way I expected it. Unfortunately, my client didn't give them to me, so I set them to 0, 30 and 2, respectively.

Thanks for your help.
