Message 415127 - Python tracker (original) (raw)

The attached _PyList_AppendTakeRef.diff has the ceval.c, but this implementation:

int _PyList_AppendTakeRef(PyListObject *self, PyObject *newitem) { assert(self != NULL && newitem != NULL); assert(PyList_Check(self)); Py_ssize_t len = PyList_GET_SIZE(self); Py_ssize_t allocated = self->allocated; assert((size_t)len + 1 < PY_SSIZE_T_MAX); if (allocated > len) { PyList_SET_ITEM(self, len, newitem); Py_SET_SIZE(self, len + 1); return 0; } if (list_resize(self, len + 1) < 0) { Py_DECREF(newitem); return -1; } PyList_SET_ITEM(self, len, newitem); return 0; }
