Raw Blame History

From 4cace55bfbbc1439d08209641e49e886b7808f20 Mon Sep 17 00:00:00 2001
From: Eric Jolibois <em.jolibois@gmail.com>
Date: Mon, 19 Jul 2021 15:23:07 +0200
Subject: [PATCH 1/3] Add python 3.10 support (#2885)
* refactor: extra `BaseConfig` and `Extra` in dedicated `config` module
* refactor: clean useless `#noqa: F401`
* refactor: clean useless `#noqa: F811`
* refactor: replace enum check
Error with 3.10
> DeprecationWarning: accessing one member from another is not supported
* refactor: avoid using `distutils` directly
error with python 3.10
> DeprecationWarning: The distutils package is deprecated and slated
> for removal in Python 3.12.
> Use setuptools or check PEP 632 for potential alternatives
* fix: `__annotations__` always exists
* fix: origin of `typing.Hashable` is not `None`
* ci: add run with 3.10.0b2
* docs: add 3.10
* feat: support `|` union operator properly
`|` operator has origin `types.Union` (and not `typing.Union`)
* fix: enum repr is different with 3.10+
* fix: error message changed a bit
change from basic `__init__` to `test_hashable_required.<locals>.MyDataclass.__init__()` (with `__qualname__`)
* fix: always exists and is not inherited anymore
* fix: avoid calling `asyncio.get_event_loop` directly
With python 3.10, calling it results in
> DeprecationWarning: There is no current event loop
* fix(ci): do not run 3.10 on linux for now
For now it can not be compiled.
Let's just skip the check on linux for now instead of tuning the CI pipeline
* fix(ci): ignore DeprecationWarning raised by `mypy` on windows
* docs: add change file
(cherry picked from commit 4a54f393ad20ee91b51cd7a49ec46771ba4f8a18)
