TypeError: 'Buffer' does not support the buffer interface

When using pypy 3.8 I get the error mentioned in the title. This doesn't seem to happen on pypy 3.9. Do you know what might be going on?

To reproduce, save the following contents as compress.py:

from io import BytesIO
from cramjam import snappy

compressed = snappy.compress_raw(b"123")
BytesIO(compressed)

And then you can use the following Dockerfile:

FROM pypy:3.8-bullseye

RUN pip install cramjam
COPY compress.py /

RUN pypy compress.py

Note: Change the dockerfile to use pypy:3.9-bullseye to see that it works in 3.9

Thanks for the reproducer!
I'll try to have a look this weekend.

Regarding this and the related issue, not ignoring.. just busy. 😅

[scottbelden]

No worries. I completely understand. And I worked around it by just using 3.9.

Came to my attention that pypy3.8 isn't developed any longer and now w/ #144 in, it tests pypy3.9 and 3.10 so this ought to be fixed now in v2.8.2 for the supported pypy versions.
