From 27580c1fb5e8cb756304f523006d832d2e3532e7 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 1 Dec 2016 14:43:22 +0100 Subject: Replace PyObject_CallFunctionObjArgs() with fastcall * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507. --- Modules/_elementtree.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Modules/_elementtree.c') diff --git a/Modules/_elementtree.c b/Modules/_elementtree.c index 71245c23d9..f3e1e9f227 100644 --- a/Modules/_elementtree.c +++ b/Modules/_elementtree.c @@ -2457,7 +2457,7 @@ treebuilder_append_event(TreeBuilderObject *self, PyObject *action, PyObject *event = PyTuple_Pack(2, action, node); if (event == NULL) return -1; - res = PyObject_CallFunctionObjArgs(self->events_append, event, NULL); + res = _PyObject_CallArg1(self->events_append, event); Py_DECREF(event); if (res == NULL) return -1; -- cgit v1.2.1
