New submission from Łukasz Langa <luk...@langa.pl>: Consider the following:
>>> it = iter(range(2**32 + 2)) >>> for _ in range(2**32): ... _ = next(it) >>> it2 = pickle.loads( ... pickle.dumps(it) ... ) >>> assert next(it) == next(it2) This assert currently fails because the reduce method for range iterator objects serializes to `int` instead of `long`. (note that running this example might take tens of minutes on your box) ---------- messages: 400360 nosy: lukasz.langa priority: normal severity: normal stage: patch review status: open title: Pickling a range iterator with an index of over sizeof(int) stores an invalid index type: behavior versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45018> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
