Re: commons fileupload

[Robert J. Carr]

Well, I set my 'setSizeThreshold()' to a fairly large number (2^24 or 
16,777,216 or 16MB, far larger than the size of my file), but it is 
still doubling in size when uploaded.

Again, strangely, I'm getting two files written, one automatically
(which I thought would be gone now?) and one manually.
The one written automatically (upload_0000002.xml) is correct (about 
1MB); a copy of the file I uploaded.  Another file, which was created 
with this line:

item.write(File.createTempFile("portaltest-", null));

Comes back as twice the size, about 2MB, as portaltest-63344.tmp.

I can/will hook up a tcp monitor, but the problem with that is, I'm
sending up a lot of data, at least 1MB of XML.  Whenever I do small
files, say ~100KB, it works fine.  So, here are my questions:

1) If I'm setting the 'setSizeThreshold()' large enough, why is it 
*still* writing out a temp file to disk?  Is this normal?

2) The documentation for 'getSizeThreshold()' says:  "Returns the size 
threshold beyond which files are written directly to disk. The default 
value is 1024 bytes".  But when I do a 'getSizeThreshold()' I get 10240. 
 Is the documentation simply stale?

3) What happens between when the uploaded file is temporarily written to 
disk, and when the 'parseRequest()' is called?  Between these two events 
is when the size problems seem to manifest.

Thanks-

Mike/Martin-

I will hook up a monitor (I'm familiar with tcpmon) but as I 
explained, it
seems to be beyond that point, as the file is written to disk correctly
when done automatically, but then written incorrectly when done manually
(or when referred to).


What's strange, though, is that nobody else has reported this kind of
problem, and the difference between the servlet and portlet code is
miniscule. The size of a file item is determined from the content itself by
the same code for both cases.

I've read about a file-writing size threshold, and perhaps this is
configurable?


Yes, it is. You can call the setSizeThreshold method on the file item
factory. See the user guide for an example.

 As I also explained, the problem only seems to happen with
large files, when they are written to disk and pass this threshold.  Not
an ideal fix, but if I just move this threshold up considerably higher,
I'm guessing it would work, and would at least allow me to see something
different.

I'll try that, and attach the moitor, and report my results.  Thanks for
the time.
