From 8cc705eabcea0436ba51ff5eb87aafa82521d2b4 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Thu, 1 Nov 2001 14:23:28 +0000 Subject: [PATCH] SF bug #477059 (my own): __del__ on new classes vs. GC. When moving objects with a __del__ attribute to a special list, look for __del__ on new-style classes with the HEAPTYPE flag set as well. (HEAPTYPE means the class was created by a class statement.) --- Modules/gcmodule.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/Modules/gcmodule.c b/Modules/gcmodule.c index 0badc23a4d..a0522a0952 100644 --- a/Modules/gcmodule.c +++ b/Modules/gcmodule.c @@ -241,7 +241,9 @@ move_finalizers(PyGC_Head *unreachable, PyGC_Head *finalizers) for (; gc != unreachable; gc=next) { PyObject *op = FROM_GC(gc); next = gc->gc.gc_next; - if (PyInstance_Check(op) && PyObject_HasAttr(op, delstr)) { + if ((PyInstance_Check(op) || + PyType_HasFeature(op->ob_type, Py_TPFLAGS_HEAPTYPE)) && + PyObject_HasAttr(op, delstr)) { gc_list_remove(gc); gc_list_append(gc, finalizers); } -- 2.40.0
