           Summary: [fileupload] FileUpload 2 gig File Size Limitation
           Product: Commons
           Version: 1.1 Final
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: File Upload
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: saden1@gmail.com

Looking through the FileUpload 1.1 code it looks like there is a limitation on
how big of a file can be received and processed. If you look at the readBodyData
method of the MultipartStream class you'll notice that an integer is being used
to keep a tally of the total number of bytes received when processing an
encapsulation. I recommend changing the type of the variable "total" to a long
in the readBodyData and wherever a tally of bytes received is done.

Created an attachment (id=17461)
 --> (http://issues.apache.org/bugzilla/attachment.cgi?id=17461&action=view)
total variable type changed from int to long

Here is a patch that that resolves the limitation (I think). This patch simply
changes type of the total variable from int to long.

Wow, I guess I never noticed that that Request.getContentLength returns an
integer. Still, the spec allows for getContentLength to return -1 (unknown
length) therefore the length of the content sent can be greater than 2 gig.

It's not quite that simple. The content length provided by the container (either
servlet or portlet) is also an integer, so there is a limitation in the
containers themselves. (See Request.getContentLength and
ActionRequest.getContentLength.)
