New submission from Kristján Valur Jónsson <krist...@ccpgames.com>:
The GC module currently relies only on the presence of a __del__ method to decide if an object can be safely collected at all. Also, there is a special case for generator objects. This patch allows any object to call an api during its traversal, PyObject_GC_Collectable(), to indicate whether it is fit to be collected at this time, overriding any presence of a __del__ method or not. This mechanism is being put in place in stackless python 2.7 because tasklets cannot always be collected depending on their runtime state, and I thought this might be a useful addition for regular python, especially since there already is such a dynamic special case for generator objects. ---------- components: Interpreter Core files: gc_collectable.patch keywords: needs review, patch, patch messages: 109099 nosy: krisvale priority: normal severity: normal status: open title: Allow objects to decide if they can be collected by GC type: feature request versions: Python 3.2 Added file: http://bugs.python.org/file17838/gc_collectable.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9141> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
