From f83d38687fec2239c517037453ed4a2191279796 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Fri, 28 Jan 2022 00:14:04 +0100 Subject: [PATCH] Port to Python 3.11 (#410) * Replace "arg == Py_None" with Py_IsNone(arg) * Replace arg->ob_type with Py_TYPE(arg) * Replace "Py_TYPE(obj) = type" with Py_SET_TYPE(obj, type). * Copy pythoncapi_compat.h from: https://github.com/pythoncapi/pythoncapi_compat * pythoncapi_compat.h provides Py_SET_TYPE() and Py_IsNone() to old Python versions.
