[New-bugs-announce] [issue20420] BufferedIncrementalEncoder violates IncrementalEncoder interface

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

The documentation of IncrementalEncoder.getstate() says:

"""
Return the current state of the encoder which must be an integer. The implementation should make sure that 0 is the most common state. (States that are more complicated than integers can be converted into an integer by marshaling/pickling the state and encoding the bytes of the resulting string into an integer).
"""

But implementation of BufferedIncrementalEncoder.getstate() is

    def getstate(self):
        return self.buffer or 0

self.buffer is "unencoded input that is kept between calls to encode()", e.g. a string.
