Below is the code from the Django view that I used with mod_python and
then with mod_wsgi, no such silliness:
--
class DownloadIterWrapper:
def __init__(self, stream, chunk_size=1024 ** 2):
self.stream = stream
self.chunk_size = chunk_size
def next(self):
data = self.stream.read(self.chunk_size)
if not data:
raise StopIteration
return data
def __iter__(self):
return self
...
response = HttpResponse(DownloadIterWrapper(download),
mimetype=file_info.get_mime(download))
download.seek(0)
return response
