Jochen Wiedmann resolved FILEUPLOAD-145.
----------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.3
         Assignee: Jochen Wiedmann

A FileSizeLimitExceededException was deferred until the complete file has been 
uploaded. Additionally, the FileSizeLimitException is now thrown immediately, 
if the attachments headers contain a content-length value, which exceeds the 
configured limit. (It is unlikely, that browsers send such a header, but one 
can try.)



> setFileSizeMax validation is happening after ENTIRE file gets uploaded

> The LimitedInputStream *IS* correctly raising a 
> FileUploadBase.FileSizeLimitExceededException in the event of a too-large 
> file.  HOWEVER, the exception isn't getting *processed* until AFTER all of 
> the data is read.  This is because of what appears to be a bug in 
> MultipartStream.ItemInputStream.close() (or a bug in close handling after the 
> FileSizeLimitExceededException is raised).  After the LimitedInputStream 
> correctly raises the file size exception, someone attempts to close the 
> MultipartStream, but the close() method repeatedly calls 'makeAvailable()' 
> which ends up reading the rest of the file upload data anyways, REGARDLESS of 
> the size limit exception being raised.
