New submission from Antoine Pitrou: This experimental patch proposes to defer generator cleanup to the frame itself. In this scheme, the generator frame's tp_clear throws the GeneratorExit if necessary, so as to call cleanup code. The generator doesn't have any tp_del anymore, as it is now impossible to resurrect a generator (the frame, though, can be resurrected; I have to add a test for that).
The net effect is that generators caught in a reference cycle can always be reclaimed, and their cleanup code is run in a valid frame. ---------- components: Interpreter Core files: gen2.patch keywords: patch messages: 187482 nosy: benjamin.peterson, ncoghlan, pitrou priority: normal severity: normal stage: patch review status: open title: Generator cleanup without tp_del type: enhancement versions: Python 3.4 Added file: http://bugs.python.org/file29959/gen2.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17807> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
