[Python-Dev] Re: C new-style classes and GC

[Jeremy Hylton]

I'm willing to believe there is a new and better way, but I don't think
I know what it is.  How do we change this code, written using the old
PyObject_GC_New() to do things the new way?

Jeremy

PyObject *
PyDict_New(void)
{
	register dictobject *mp;
	if (dummy == NULL) { /* Auto-initialize dummy */
		dummy = PyString_FromString("<dummy key>");
		if (dummy == NULL)
			return NULL;
#ifdef SHOW_CONVERSION_COUNTS
		Py_AtExit(show_counts);
#endif
	}
	mp = PyObject_GC_New(dictobject, &PyDict_Type);
	if (mp == NULL)
		return NULL;
	EMPTY_TO_MINSIZE(mp);
	mp->ma_lookup = lookdict_string;
#ifdef SHOW_CONVERSION_COUNTS
	++created;
#endif
	_PyObject_GC_TRACK(mp);
	return (PyObject *)mp;
}
