New submission from Min RK: Reference counts appear to be ignored at process cleanup, which allows inter-dependent `__del__` methods to hang on exit. The problem does not seem to occur for garbage collection of any other context (functions, etc.).
I have a case where one object must be cleaned up after some descendent objects. Those descendents hold a reference on the parent and not vice versa, which should guarantee that they are cleaned up before the parent. This guarantee is satisfied by Python 3.3 and below, but not 3.4. The attached test script hangs at exit on most (not all) runs on 3.4, but exits cleanly on earlier versions. ---------- components: Interpreter Core files: tstgc.py messages: 217168 nosy: minrk priority: normal severity: normal status: open title: refcounts not respected at process exit versions: Python 3.4 Added file: http://bugs.python.org/file35041/tstgc.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21351> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
