On the top of my swfupload.js there is this comment:
* SWFUpload Revision 7.0 by Jacob Roberts, Oct 2007, http://linebyline.blogspot.com

I was looking for the official site, but on google i've found only the oldsite, then I've downloaded it from here: http://swfupload.praxion.co.za/

I think it's not a problem of set_time_limit related cause the upload is right, i can see my large files (over 150Mb) uploaded correctly.

I'll do a try, you can confirm is the right version of swfupload?

Thank you very much, Bye

edit: I've downloaded the 2.0.1 version, I've tried the demo and it works, can you suggest me what type of debug can I do?
There's a way to see the comunication between tha flash object and the php file?

thank you again

re-edit:
I've tried to modify the application demo.
If in the upload.php file I put :

move_uploaded_file($_FILES['Filedata']['tmp_name'], 'd:/test.avi');

(the location of the uploaded file will be in another disk different from the one that stores the php temp dir where the files goes)

The time consumed in this operation is approx 40 seconds, and after this time I find my file in the right location, but it seems that the uploadSuccess function don't wait enough.

Can you try for me?
I've did this try:

file upload.php

<?php
set_time_limit(0);
sleep(60);
echo "UPLOAD COMPLETED";


Then I called it with my browser, and after 60 seconds I can se the echo, no errors regarding timeout.

Then I tried with the application example, calling this upload.php and if I reduce the number of seconds I can see the result of the uploadSuccess function.

Thank you

Now I've switched to version 2.0.1, the flash8 version seems to fire everytime the function uploadSuccess, but if the time of wait is long I receive "undefined" in server data.

The flash 9 version, doesn't wait for the response and doesn't fire the upload success function.

Have you did my try?

Simply put a sleep(60) on the upload.php of the application demo example..

Thank you very much.

bye

You got time to try ?
I'm going to close the project and I've to solve it.

Sorry, I don't want to be impolite...

Hi there,

I'm having the same problem... although the solution posted here doesn't sound that appealing to me, and my problem seems to be showing up round the 5MB mark!

I do think it could have something to do with the response time... The reason I suspect this is that I am doing a lot of image processing once the file is uploaded, and before I send a response. This can take up to a minute with some files because I'm extracting exif, as well as creating thumbnails for pdfs, psds, tiffs, etc. This could explain why some people are experiencing problems with 150mb files, and i'm experiencing problems with 5mb files. Everything works perfectly fine with smaller files.

fyi:
- I am using rails
- the problem occurs on windows/linux regardless
- tested on on ff, ie, safari. Problem exists on all of them.
- the file is uploaded, processed, and stored correctly, but communication between flash and the server seems to be cut at some point.

Thanks,
Jonzo.

I did a little bit of testing. I found that after about 30 seconds of no activity Flash terminates the connection (at least on its end). It looks like the PHP script finishes and returns its output. It looks like PHP still thinks the connection is open.

It's just one flash bug after another. A quick Google search and review of the ActionScript documentation did not turn up any information.

My recommendation is to avoid doing a lot of processing on the file. I would do something like what gianiaz suggested. But I'd probably allow the file upload to finish and return properly and then use AJAX to begin the post-processing stuff (by calling some other script that will do this).

Another solution is to return some data every 10 seconds or so. Implementing this depends on your server-side language and server configuration. But, I was able to make the Application Demo survive a "sleep" of 5 minutes using the following:

<?php
set_time_limit(0);

echo "I finished working for: " . ($times_to_loop * $time_to_sleep) . " seconds";
?>


The server output will look like: "..............................I finished working for: 300 seconds". In my uploadSuccess handler I have to remove all the "." characters from the beginning of my server_data.

Implementing this in a real application might be difficult.

Hi, I've quite the same problem with the 2.0.2

I've isolated the multi-instance demo script (flash8) with the nice graceful degradation plugin ! (real cool stuff !)

The upload is 100% fine with 7~8Mo files
Up to this size, the script shows "Complete"
(my upload bandwidth stays busy for a couple of seconds after)

Just tested the 2.1 Beta... same thing...
Note : the debug module says (after the upload network activity stopped) that the upload is in progress and cannot upload another file

And finally, there's no file in my folder !!!

How to know if this is a problem of server or plugin ?
Is there a soluce ?
Thanks for help

I'm not familiar with the Rails particulars. The issue is that you have a 30 second timeout in which to complete all server side processing. There are 2 general solutions:

1) Send data before the 30 second timeout (flushing buffers, etc).
2) Do the long running process in a separate thread and allow the main request to return. The downside is that if there is an error you can't return it.

You may also want to check your server's script execution limits. In PHP the default is 30 seconds and you could be running into an issue there as well.

@gyphie 1) : I'm not able to flush buffers, I think this is not intended in Rails.
@gyphie 2), @jonzo : Sure, this is a possible solution but it's quite much work to switch our upload-area to async processing. I will drop this task to my todo-list
@gyphie 30-sec-timeout : IMHO there is no such limit in Rails.

I will try gianiaz's solution, but I'm not sure wheter I understand it.
His "checkUpdate()" function ( "interval = setInterval('checkUpload('')', 3000);" ) does an AJAX call, but via JavaScript, not via the open Flash-connection to the server ... I'll give it a try ...

Thanks for your answers,

Hi All,

I have been working on the same problem with SWFUpload (which is awesome!)...

I am uploading some files and running a long processing step immediately after upload. This step is essential to the functionality, so I would prefer to process after each upload, rather than to make it into a second step. I do not mind having users wait a couple minutes to run this long process.

I am running into this 30 second timeout/upload problem. What I have been trying is to send data so the SWFUpload does not close its connection. I am doing this as follows (pseudocode):

def create
extract = Thread.new { doExtract }
hack = Thread.new {
loop do
if extract.alive?
#do something
# ???? #
sleep 5
else
break
end
end
}
end

So basically, I spawn two threads, with the second one checking to see every 5 sec, if the extract thread is still alive. The problem is, I don't know what command to use to send something back to avoid termination. I tried outputting to the console using (and even trying to flush the buffer):
puts "Alive"
$stdout.flush

but to no avail -- what call do I need to make here in order to tell the uploader to not terminate?

Thanks!
