StreamingBody Issue in Record Mode

Today I had the problem with the following code in record mode:

            stdout_key = self._s3.Object(bucket_name='somebucket',
                                         key='{}/stdout'.format(location))
            result_output = stdout_key.get()['Body'].read()

No matter what, result_output was always ''. After some digging, I was able to determine that the stream was already read.

(Pdb) test = stdout_key.get()['Body']
(Pdb) test._raw_stream.tell()
5

Important note: the tests run fine and work as expected when in playback mode, and the content of the StreamingBody is saved correctly to the cassette.

My assumption: Placebo is read()ing the StreamingBody while in record mode so that it can save it to the cassette.

Is there any way we can still present the results correctly? I’d like to avoid having my tests fail in record mode and then pass during playback mode. 😛
