SWFUpload IO Error?

Question

Flask

Hello!

The problem is the following. There is a website book.studia52.ru where anyone can fill out a form and place an order. In addition to entering data, he must upload a photo and archive. The download is done using a flash drive.

Some people keep getting an IO error on boot and I can't figure out why. Based on feedback, I'm assuming this problem is only on Vista. When testing on the seven and XP, such an error never occurred. On whist, it sometimes appears, but when you try again, everything is ok.

Used SWFUpload 2.2.0, SWFUpload 2.5.0, Uploadify 2.1.4. The error doesn't go anywhere. Tested on Vista in Firefox, Chrome and IE. The error can appear in any. It does not depend on the file size.

The site is written in Python, using the Flask microframework.

There is an IO Error in the Apache logs, but it does not apply to loading (if the flash drive gives an error when loading a file, nothing appears in the logs).

Naturally, I googled this problem. But I didn't find an answer. mod_security is not used. There is no authentication.

Tried several times to upload files here demo.swfupload.org/v250beta3/ , no errors. But not the fact that everything is fine there. If there is an error, I will write.

Thanks for the help!

Answer 1

There was such a problem on habrastore due to the fact that the file size was exceeded (meaning the width or height)

Answer 2

Try to send the file in chunks and collect on the server side. It helped me at one time with the same damned IOError from Uploadify.

Answer 3

And what does SWFUpload itself write in the debug console?
Once there was a similar problem, but it was related to IDN domains (.РФ)

Answer 4

I also saw the same problem. At random, I determined that the antivirus was the culprit, in my case, KIS. When the antivirus was disabled, everything worked without problems.
