Handle Flash IOError 2038 and 1000 (how?)

[Eegee]

Hello,

I'm not quite sure if I should post this to the forum or post it here, but I think it is a feature request, so here goes...

I'm trying PLUpload 2.1(.1), but cannot seem to catch certain Flash errors. I tried a lot of debugging and adding code, but I cannot get enough grasp on the code because of my lack of experience with Flash development and moxie internals. :-o

I would like to have Flash I/O Error # 2038 and Error # 1000 (out of memory) captured by moxie, and then routed through to plupload and jquery.ui.plupload, just like plupload.HTTP_ERROR eventually gets handled to output an error message, when the receiving server isn't listening.

Error # 1000 gets thrown when clicking on the upload button, trying to chunk-upload a file that is too large for Flash to handle at that moment (for instance a 2 GB file). Then I would like to see the same error message as for IMAGE_MEMORY_ERROR, 'Runtime ran out of available memory.'. Now the file just stays in the queue, looking as if it is still processing.

Error # 2038 gets thrown after selecting a file that is larger than uint.MAX_VALUE (cq Number, 4294967295), on the following code lines:

flash.net::FileReference/get size()
at com::Blob()[D:\Users\user\Documents\GitHub\moxie\src\flash\src\com\Blob.as:62]
at com::File()[D:\Users\user\Documents\GitHub\moxie\src\flash\src\com\File.as:36]
at com::FileInput/onDialogEvent()[D:\Users\user\Documents\GitHub\moxie\src\flash\src\com\FileInput.as:150]

I think this error could be best handled in onDialogEvent, but I don't have enough experience in Flash development to implement it properly.

So I added an uncaughtErrorHandler in Moxie.as (ugly, but I had to try something) like so:

private function uncaughtErrorHandler(event:UncaughtErrorEvent):void
{
    if (event.error is Error)
    {
        var error:Error = event.error as Error;
        _fireEvent(uid + "::Exception", { name: getQualifiedClassName(error).replace(/^[^:*]::/, ''), code: error.errorID });
    }
    else if (event.error is ErrorEvent)
    {
        var errorEvent:ErrorEvent = event.error as ErrorEvent;
        _fireEvent(uid + "::Exception", { name: getQualifiedClassName(errorEvent).replace(/^[^:*]::/, ''), code: errorEvent.errorID } );
    }
    else
    {
        // a non-Error, non-ErrorEvent type was thrown and uncaught
    }
}

and in _init, adding the line:

loaderInfo.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR, uncaughtErrorHandler);

Then I tried capturing the exceptions in RuntimeClient.js (moxie.js), line 72, the commented line:

/*runtime.bind('Exception', function() { });*/

which probably also isn't a good idea since it is commented out...

I do get those two exceptions # 2038 and # 1000 in this anonymous function (in argument 2), but I don't know handle it further to get it passed to jquery.ui.plupload. I tried lots of trigger('Error') / RuntimeError etc, but I realise I'm kind of fooling around trying, not having enough experience.

I've used plupload 1.5.7 previously, and this could handle Flash error 2038 more how I would want it, adding an error on top of the widget.

Davit, could you please shed your light on how to handle these Flash errors? I understand this might not be an easy task, for me it sure isn't (I'm trying hard the last few days, to no avail :-/ ) but I'm hoping you have some time to investigate.

If you require more information, please say so and I will try to provide it.

That's quite an investigation there actually. I will look into it. Thanks for your time and efforts.
