New submission from Serhiy Storchaka: Some time ago Victor proposed in issue16445 a large patch (275 changes) which replaces "Py_DECREF(expr); expr = NULL;" to safer "Py_CLEAR(expr);". That patch contained was so large because it included cases where expr is just a local variable, which are safe in general.
Here are much simpler patches which make replacements only for complex expressions. These patches (as Victor patch) are generated automatically by the Coccinelle tool (http://coccinelle.lip6.fr/). ---------- components: Extension Modules, Interpreter Core files: py_clear.spatch messages: 209640 nosy: asvetlov, haypo, serhiy.storchaka, skrah priority: normal severity: normal stage: patch review status: open title: Use Py_CLEAR to safe clear attributes type: crash versions: Python 2.7, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file33793/py_clear.spatch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20437> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
