I would use full os.fstat here since it doesn't simply to figure out what fstat is and where it comes from. Also look on the other imports from stdlib.

self.headers[hdrs.CONTENT_LENGTH] = str(size)
self.chunked = False
else:
self.chunked = True
if hasattr(data, 'mode'):
if data.mode == 'r':
raise ValueError('file {!r} should be open in binary mode'
