Added an import that was missed in [8193]. Thanks Karen Tracey. Fixed #8143.

import os

import sha

from django.core.files.uploadedfile import UploadedFile

from django.http import HttpResponse, HttpResponseServerError

from django.utils import simplejson

from uploadhandler import QuotaUploadHandler

from django.utils.hashcompat import sha_constructor

def file_upload_view(request):

    """

            continue

        submitted_hash = form_data[key + '_hash']

        if isinstance(value, UploadedFile):

            new_hash = sha.new(value.read()).hexdigest()

            new_hash = sha_constructor(value.read()).hexdigest()

        else:

            new_hash = sha.new(value).hexdigest()

            new_hash = sha_constructor(value).hexdigest()

        if new_hash != submitted_hash:

            return HttpResponseServerError()
