From 7bfb42d5b7721ca26e33050d025fec5c43c00058 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Mon, 5 Dec 2016 17:04:32 +0100 Subject: Issue #28858: Remove _PyObject_CallArg1() macro Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue. --- Include/abstract.h | 5 +---- Modules/_asynciomodule.c | 6 +++--- Modules/_collectionsmodule.c | 3 ++- Modules/_elementtree.c | 11 ++++++----- Modules/_pickle.c | 2 +- Modules/_sre.c | 2 +- Modules/pyexpat.c | 2 +- Objects/abstract.c | 2 +- Objects/fileobject.c | 2 +- Objects/genobject.c | 2 +- Objects/typeobject.c | 6 +++--- Python/_warnings.c | 2 +- Python/codecs.c | 2 +- Python/errors.c | 2 +- Python/sysmodule.c | 2 +- 15 files changed, 25 insertions(+), 26 deletions(-) diff --git a/Include/abstract.h b/Include/abstract.h index 900ef23..3dfac65 100644 --- a/Include/abstract.h +++ b/Include/abstract.h @@ -338,10 +338,7 @@ xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx*/ _PyObject_FastCallDict((func), (args), (nargs), NULL) #define _PyObject_CallNoArg(func) \ - _PyObject_FastCall((func), NULL, 0) - -#define _PyObject_CallArg1(func, arg) \ - _PyObject_FastCall((func), (PyObject **)&(arg), 1) + _PyObject_FastCallDict((func), NULL, 0, NULL) PyAPI_FUNC(PyObject *) _PyObject_Call_Prepend(PyObject *func, PyObject *obj, PyObject *args, diff --git a/Modules/_asynciomodule.c b/Modules/_asynciomodule.c index 4e8f74a..ea02a5e 100644 --- a/Modules/_asynciomodule.c +++ b/Modules/_asynciomodule.c @@ -257,7 +257,7 @@ future_get_result(FutureObj *fut, PyObject **result) return -1;
