I agree with Chris that the issue of not hanging is independent of the question what to do about the cycle. The ExitStack issue that brought this issue about is now fixed in ExitStack (see issue25786, issue27122). If we take a step back from that, the situation is this: SetObject's cycle detection loop is intended to prevent the creation of new cycles when adding a new context link. It hangs when the exception chain has a pre-existing cycle. That pre-existing cycle is arguably a bug, and I'm not sure it's SetObject's job to do anything about it. So I would suggest to: (1) Make it not hang, ASAP because this is a bug in SetObject. (2) Leave the cycle alone. ---------- nosy: +iritkatriel _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue25782> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
