[issue27623] int.to_bytes() and int.from_bytes(): raise ValueError when bytes count is zero

[Martin Panter]

Martin Panter added the comment:

I’m not familiar with the implementation, but it does seem like this should be fixed within _PyLong_AsByteArray().

Also, what about int.from_bytes(b"", ..., signed=True)? There are existing tests for this case, but it seems like it should be an error, rather than returning zero.
