Flash File Uploader

[bcoffin]

I'm using the file.upload feature of AS3 to show upload progress and it seems i'm creating a server side process that just grows and grows in memory demand. Uploading a 110MB file draws close to 720MB of memory at the time that i canceled the upload. Any suggestions?

 

I've removed LOADS of peripheral functionality from this to simplify.

But this is the meat+potatoes of the actionscript that's doing the upload (and spiking server memory):

_root.onEnterFrame = function() {
if (this.getBytesLoaded()/this.getBytesTotal()>0.99) {
	_root.onEnterFrame = function() {
		//trace ("onEnterFrame called");
	};
}
};

var m:MovieClip = this;
var a:Boolean = false;

import flash.net.FileReference;
var selected_file = undefined;
var filetype = undefined;

//used later in case typing fails*
var file_monitor = new Object();


setSelected = function (file) {
selected_file = file;
file_name.text = file.name;
};

file_monitor.onSelect = function(file) {

>>> buncha tests here removed
} else if (file.name) {
	setSelected(file);
} else {
	alert("Please select a file to upload.");
}

};

file_monitor.onOpen = function(file) {
progress_bar.setStatus("Uploading...");
time_started = getTimer();
};
file_monitor.onProgress = function(file, bytesLoaded, bytesTotal) {
progress_bar.setProgress(bytesLoaded,bytesTotal,getTimer()-time_started);
};

var file = new flash.net.FileReference();
file.addListener(file_monitor);


upload_btn.onRelease = function() {
upload_file("upload.php?custom_flags=values");
};
upload_file = function (dst) {
	file.upload(dst);
};

 

thanks for any suggestions/theories

Don't use Flash to check the progress. I recently made some file upload application similar to flickr's but avoided using Flash. I used Javascript to get the progress via uploadprogress_get_info().

 

Here's something with an explanation:

By the way, are you setting up _root manually? This is AS3 right?

Why not use Flash?

I can't access that link you provided.

Yes, _root is the root.
