Subject [jira] [Created] (FILEUPLOAD-211) [fileupload] fails with transfer-encoding: chunked when multi-part file section includes chunked data

Rob Smart created FILEUPLOAD-211:
------------------------------------

             Summary: [fileupload] fails with transfer-encoding: chunked when multi-part file
section includes chunked data
                 Key: FILEUPLOAD-211
                 URL: https://issues.apache.org/jira/browse/FILEUPLOAD-211
             Project: Commons FileUpload
          Issue Type: Bug
    Affects Versions: 1.2.2
         Environment: Tomcat 7, java 1.6, osx
            Reporter: Rob Smart
            Priority: Minor


When performing multi-part file upload using chunked data, if a multi-part section includes
separate data chunks it is not correctly parsed and causes FileUpload to throw "MalformedStreamException:
Stream ended unexpectedly"

Having chunked content within a multi-part boundaries is as far as I am aware valid.

The reason my client has chunked content within file boundaries is that an audio file is uploaded
as it is being recorded.

Example with chunked data within file boundary

POST /UploadServlet HTTP/1.1
User-Agent: test
Host: 192.168.1.2:9080
Connection: keep-alive
Transfer-Encoding: chunked
Content-Type:multipart/form-data; boundary=----WebKitFormBoundarykhPSttlPFVKSMhff

99
------WebKitFormBoundarykhPSttlPFVKSMhff
Content-Disposition: form-data; name="file"; filename="testfaces.wav"
Content-Type: application/octet-stream
