From 64de7911d2938fc3601fec39c08008465b9d4f6f Mon Sep 17 00:00:00 2001 From: Nick Cao Date: Tue, 7 Feb 2023 17:12:50 +0800 Subject: [PATCH] python: enum: fix build for Python 3.11 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Python 3.9 introduced Py_SET_SIZE function to set size instead of relying on Py_SIZE() as a macro [3.9]. Python 3.10 started to encourage to use Py_SET_SIZE instead of assigning into return value of Py_SIZE [3.10]. Python 3.11 flips the switch, turn Py_SIZE into a function [3.11], thus Py_SIZE(obj) will be a rvalue. We need to use Py_SET_SIZE to set size now.
