[New-bugs-announce] [issue31722] _io.IncrementalNewlineDecoder doesn't inherit codecs.IncrementalDecoder

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

It is documented that io.IncrementalNewlineDecoder inherits codecs.IncrementalDecoder. And the Python implementation does. But the C implementation doesn't.

>>> issubclass(_pyio.IncrementalNewlineDecoder, codecs.IncrementalDecoder)
True
>>> issubclass(_io.IncrementalNewlineDecoder, codecs.IncrementalDecoder)
False
>>> issubclass(io.IncrementalNewlineDecoder, codecs.IncrementalDecoder)
False
