File download doesn't stop

Description

Hello everybody,

with the latest FileZilla version on Windows I've
noticed a problem while I was downloading the German
version of the Wikipedia DVD from a download mirror. It
seems that there is a wrap around of an 32 bit variable
because FileZilla keeps downloading over and over. The
GUI reaches 100% but it is still downloading and after
a few hours I had a file of 20 GB on my harddisk.
Please download the following file and test it for
yourself.

ftp://ftp.freenet.de/pub/filepilot/windows/bildung/wikipedia/Wikipedia_3.3_big.iso
(7.5 GB)

Best regards

Michael

FileZilla stores filesizes as 64bit integers, I've
previously tested it with files over 4GB in size and found
no problems.

However, since you provided a link to the file, I could run
some tests with the server. It seems that the server does
not support resume of large files, there is a 32 bit integer
overflow in the server itself.

In the next major version of FileZilla, I'll add a small
test to detect this particular problem.

Please try to download the file from a different mirror.

I've implemented a resume check in FileZilla 3.
(http://filezilla-project.org/nightly.php)

If you would the file from download from above server and
there's a disconnect in between so FileZilla has to resume,
FileZilla will detect that the server cannot properly resume
the file and abort.
