Use `semantic versioning `__. -- Build with ``pipx run build`` -- Sign the packages with gpg ``gpg --detach-sign -a dist/python_can-X.Y.Z-py3-none-any.whl``. -- Upload with twine ``twine upload dist/python-can-X.Y.Z*``. +* You can monitor the release status on: + `PyPi `__, + `Read the Docs `__ and + `GitHub Releases `__. diff --git a/doc/installation.rst b/doc/installation.rst index ff72ae21b..822de2ce0 100644 --- a/doc/installation.rst +++ b/doc/installation.rst @@ -21,6 +21,13 @@ Install the ``can`` package from PyPi with ``pip`` or similar:: $ pip install python-can[serial] +Pre-releases +------------ + +The latest pre-release can be installed with:: + + pip install --upgrade --pre python-can + GNU/Linux dependencies ---------------------- From e4d605b1d7b3a645c01ed3f064f7bc76410c5acc Mon Sep 17 00:00:00 2001 From: zariiii9003 <52598363+zariiii9003@users.noreply.github.com> Date: Wed, 23 Jul 2025 21:20:29 +0200 Subject: [PATCH 4/7] minor type annotation fixes --- can/bus.py | 3 +-- can/interfaces/virtual.py | 12 ++++-------- 2 files changed, 5 insertions(+), 10 deletions(-) diff --git a/can/bus.py b/can/bus.py index 0d031a18b..f053c4aa7 100644 --- a/can/bus.py +++ b/can/bus.py @@ -11,7 +11,6 @@ from time import time from types import TracebackType from typing import ( - Any, Callable, Optional, Union, @@ -69,7 +68,7 @@ class BusABC(metaclass=ABCMeta): @abstractmethod def __init__( self, - channel: Any, + channel: Optional[can.typechecking.Channel], can_filters: Optional[can.typechecking.CanFilters] = None, **kwargs: object, ): diff --git a/can/interfaces/virtual.py b/can/interfaces/virtual.py index aa858913e..6b62e5ceb 100644 --- a/can/interfaces/virtual.py +++ b/can/interfaces/virtual.py @@ -12,22 +12,18 @@ from copy import deepcopy from random import randint from threading import RLock -from typing import TYPE_CHECKING, Any, Optional +from typing import Any, Optional from can import CanOperationError from can.bus import BusABC, CanProtocol from can.message import Message -from can.typechecking import AutoDetectedConfig +from can.typechecking import AutoDetectedConfig, Channel logger = logging.getLogger(__name__) # Channels are lists of queues, one for each connection -if TYPE_CHECKING: - # https://mypy.readthedocs.io/en/stable/runtime_troubles.html#using-classes-that-are-generic-in-stubs-but-not-at-runtime - channels: dict[Optional[Any], list[queue.Queue[Message]]] = {} -else: - channels = {} +channels: dict[Optional[Channel], list[queue.Queue[Message]]] = {} channels_lock = RLock() @@ -58,7 +54,7 @@ class VirtualBus(BusABC): def __init__( self, - channel: Any = None, + channel: Optional[Channel] = None, receive_own_messages: bool = False, rx_queue_size: int = 0, preserve_timestamps: bool = False, From 9b4b1a50b1267468e0ce57d666db465b17683ca0 Mon Sep 17 00:00:00 2001 From: zariiii9003 <52598363+zariiii9003@users.noreply.github.com> Date: Wed, 23 Jul 2025 22:15:54 +0200 Subject: [PATCH 5/7] add missing `install` cmd --- doc/development.rst | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/doc/development.rst b/doc/development.rst index 4ee3da5e5..62378fd34 100644 --- a/doc/development.rst +++ b/doc/development.rst @@ -122,7 +122,7 @@ Step-by-Step Contribution Guide python -m venv .venv .venv\Scripts\activate # On Windows source .venv/bin/activate # On Unix/macOS - python -m pip --upgrade pip + python -m pip install --upgrade pip pip install -e . --group dev 3. **Make Your Changes** From 91b50d671ee9fd466889f8f19d909883307b7daa Mon Sep 17 00:00:00 2001 From: zariiii9003 <52598363+zariiii9003@users.noreply.github.com> Date: Wed, 23 Jul 2025 22:34:48 +0200 Subject: [PATCH 6/7] disable free-threaded tests, TestThreadSafeBus::test_send_periodic_duration is flaky --- .github/workflows/ci.yml | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 66a37f926..8c3bb407f 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -20,8 +20,10 @@ jobs: "py310", "py311", "py312", - "py313", "py313t", - "py314", "py314t", + "py313", + "py314", +# "py313t", +# "py314t", "pypy310", "pypy311", ] From 26ea51f30895527dca5f4b2caba352260f2ea4f7 Mon Sep 17 00:00:00 2001 From: zariiii9003 <52598363+zariiii9003@users.noreply.github.com> Date: Thu, 24 Jul 2025 01:05:40 +0200 Subject: [PATCH 7/7] update docs as requested by review --- doc/development.rst | 102 ++++++++++++++++++++++---------------------- 1 file changed, 50 insertions(+), 52 deletions(-) diff --git a/doc/development.rst b/doc/development.rst index 62378fd34..97c175ada 100644 --- a/doc/development.rst +++ b/doc/development.rst @@ -77,53 +77,57 @@ Step-by-Step Contribution Guide 2. **Set Up Your Development Environment** - You can use either `pipx `__ or `uv `__ - to install development tools.
