New submission from Yury Selivanov: Looks like we have a refleak somewhere in the system that typing.py is exposing.
The following code exposes the refleak: def test_refleak(self): T = typing.TypeVar('T') class C(typing.Generic[T], typing.Mapping[int, str]): ... The change that first triggered the leak is 8f0df4db2b06. I'm not an expert in typing.py, but I suspect that the real bug must be somewhere in CPython core. Guido, do you have any idea how 8f0df4db2b06 could trigger this? ---------- components: Library (Lib) messages: 280407 nosy: gvanrossum, ned.deily, serhiy.storchaka, yselivanov priority: release blocker severity: normal stage: needs patch status: open title: refleak in typing.py type: behavior versions: Python 3.6, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28649> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
