Subject [jira] Created: (FILEUPLOAD-141) Remove FileItems if FileUploadBase.parseRequest() fails
Date Mon, 23 Jul 2007 10:55:32 GMT
Remove FileItems if FileUploadBase.parseRequest() fails

                 Key: FILEUPLOAD-141
             Project: Commons FileUpload
          Issue Type: Improvement
    Affects Versions: 1.2
         Environment: commons-fileupload is used for parsing multipart/form-data POST requests
in servlets.
OS: Linux
            Reporter: Marcus Klein

If the method FileUploadBase.parseRequest() throws a FileUploadException, the already parsed
FileItem objects are not accessible and removed by the garbage collector. Now expect a fileupload
that fills the servers hard disc with FileItems until no space is left on the device. The
method parseRequest() throws a FileUploadException and there are several FileItem objects
that still exist in the device because the garbage collector does not run and removes them.
This causes failing fileuploads until the garbage collector runs and removes the lost FileItem
objects. I suggest calling FileItem.delete() on all FileItem objects created in the method
FileUploadBase.parseRequest() if the method is left with a FileUploadException.
