New submission from Michał Bartoszkiewicz <e...@navalgo.com>:
The following code, which seems reasonable:
import io
import pickle
class Pickler(pickle.Pickler):
def persistent_id(self, obj):
return super().persistent_id(obj)
Pickler(io.BytesIO()).dump(42)
crashes with:
RecursionError: maximum recursion depth exceeded while calling a Python object
It works perfectly when inheriting from pickle._Pickler (the Python
implementation).
