FileUpload temp files never get removed also they get tracked
Hi,
I'm using the FileUpload Component. The component creates temporary files
"upload....tmp".
I set some breakpoints to see what happens.
In DiskFileItem i can see that the File is added to the FileCleaner:
FileCleaner.track(tempFile, this);
but the File never gets removed from Disk.
I also added the apache commons FileCleanerCleanup -Listener to my web.xml.
<listener-class>
org.apache.commons.fileupload.servlet.FileCleanerCleanup
</listener-class>
Is this a bug or am i missing something?
If it's a bug, is there a workaround?
Thanks for any suggestions.
I'm using wicket 1.4.17

Hi,
I don't remember how 1.4.x works exactly in this code but for 1.5 we
improved it by creating an interface
org.apache.wicket.util.file.IFileCleaner which is configured in
org.apache.wicket.settings.IResourceSettings#setFileCleaner().
By default it uses Apache-Commons FileCleaningTracker which uses a
Thread to do its work. But now Google AppEngine users can provide
their own impl if needed too.
org.apache.wicket.protocol.http.WebApplication#internalDestroy() calls
IFileCleaner#destroy() so it should clean when the app is going down.
Put a breakpoint in
org.apache.wicket.util.file.FileCleaningTracker.Reaper#run() and see
what happens.

Thanks for your reply Martin!
After i declared the commons FileCleaner interface in my web.xml the file
was removed after my session timed out. Obviously i was just to impatient.
It also went through the breakpoint in the reaper thread.
I thin this functionality is enough for my needs.
Thank you!
