The inheritance from io.RawIOBase seems fine.

I have a patch that appears to fix this bug http://bugs.python.org/file12361/urllib-chunked.diff but I'm not sure about its interaction with the io module and RawIOBase. Is there a new IO expert who could take a look at it for me?

It simply ignores the fact that it's reading a chunked response and includes the chunked header data is payload data. The original bug was reported in September, but no one noticed it. It was reported again recently.

http://bugs.python.org/issue3761 http://bugs.python.org/issue4631 I suspect we'd want to get a 3.0.1 out as soon as this is fixed, but that's not my call. Jeremy
