My C compiler gives me a warning which on inspection I believe about an uninitialized variable usage at cPickleCache.c line 392. The code is static PyObject * cc_invalidate(ccobject *self, PyObject *args) { PyObject *inv, *key, *v; int i; if (PyArg_ParseTuple(args, "O!", &PyDict_Type, &inv)) { for (i=0; PyDict_Next(inv, &i, &key, &v); ) if (key==Py_None) { /* Eek some nitwit invalidated everything! */ for (i=0; PyDict_Next(self->data, &i, &key, &v); ) _invalidate(self, key); break; } else _invalidate(self, key); PyDict_Clear(inv); } else { PyErr_Clear(); UNLESS (PyArg_ParseTuple(args, "O", &inv)) return NULL; if (PyString_Check(inv)) _invalidate(self, key); /*possible error*/ else if (inv==Py_None) /* All */ for (i=0; PyDict_Next(self->data, &i, &key, &v); ) _invalidate(self, key); else { int l; -- Robin Becker
