杀死python3.X中的所有进程和线程 [英] Killing all processes and threads in python3.X

问题描述

我正在编写一个UI包装器，以使用esptool.py读取一些信息

I'm writing a UI wrapper for reading some info using esptool.py

我有两个活动线程:UI和处理-SerialReader. UI类具有对SerialReader的引用，并且在获取退出命令时应停止SerialReader.

I have two active threads: UI and procesing - SerialReader. UI class has reference to the SerialReader and should stop SerialReader when it gets the exit command.

问题是我调用esptool命令，该命令陷入尝试通过串行连接读取数据的问题.

The problem is that I call esptool command which gets stuck in trying to read data over serial connection.

class SerialReaderProcess(threading.Thread):

    def __init__(self, window):
        super().__init__()
        self.window = window
        self.logger = window.logger
        self.window.set_thread(self)
        self._stop_event = threading.Event()

    def run(self):
        ...
        #read chip id
        esptool.main(['chip_id'])
        ...

    def stop(self):
        self._stop_event.set()

    def stopped(self):
        return self._stop_event.is_set()

我想要的是杀死该程序的所有活动进程.当我调用关闭UI并调用serialReaderProcess.stop()时，它不会停止该过程.我可以在控制台上看到esptool的输出.

What I want is to kill all active process of this program. When I call close the UI and call serialReaderProcess.stop() it doesn't stop the process. I can see the output of esptool on the console.

我不在乎是否中断任何事情，没有数据会被破坏.

I don't care if I interrupt anything, no data can be corrupted.

我尝试sys.exit(0)无济于事. 我已经研究了问题，但是找不到解决方案.

I've tried sys.exit(0) to no avail. I've researched the problem but couldn't find a solution.

操作系统是Ubuntu，我不在乎跨平台功能，但是它们会很好

The OS is Ubuntu and I don't care about cross-platform features, but they would be nice

推荐答案

如注释中所述，将线程设置为Daemon可以解决问题:

As stated in comments, setting the thread as Daemon solved the problem:

super().__init__(daemon=True)

程序退出时，守护进程线程将自动终止.

Daemon threads are automatically killed when the program quits.
