Patrick Williams | 2194f50 | 2022-10-16 14:26:09 -0500 | [diff] [blame] | 1 | From f83d38687fec2239c517037453ed4a2191279796 Mon Sep 17 00:00:00 2001 |
| 2 | From: Victor Stinner <vstinner@python.org> |
| 3 | Date: Fri, 28 Jan 2022 00:14:04 +0100 |
| 4 | Subject: [PATCH] Port to Python 3.11 (#410) |
| 5 | |
| 6 | * Replace "arg == Py_None" with Py_IsNone(arg) |
| 7 | * Replace arg->ob_type with Py_TYPE(arg) |
| 8 | * Replace "Py_TYPE(obj) = type" with Py_SET_TYPE(obj, type). |
| 9 | * Copy pythoncapi_compat.h from: |
| 10 | https://github.com/pythoncapi/pythoncapi_compat |
| 11 | * pythoncapi_compat.h provides Py_SET_TYPE() and Py_IsNone() to old |
| 12 | Python versions. |
| 13 | |
| 14 | Upstream-Status: Backport [https://github.com/pybluez/pybluez/commit/5096047f90a1f6a74ceb250aef6243e144170f92] |
