[issue23093] repr() on detached stream objects fails

[Martin Panter]

New submission from Martin Panter:

Patch to fix the underlying issue I mentioned in msg230955. After calling detach() on one of the BufferedIOBase wrappers or a TextIOWrapper, most operations will raise an exception. My patch ensures the following operations are still usable, because they are documented and it doesn’t make sense to disable them:

repr(stream)
stream.encoding
stream.errors
stream.line_buffering
