Remove FileItems if FileUploadBase.parseRequest() fails
-------------------------------------------------------
Key: FILEUPLOAD-141
URL: https://issues.apache.org/jira/browse/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.
