python多线程join方法导致不能接收信号今天写一个小工具，开启多个线程，在子线程里循环执行任务，发现不能退出程序，然后折腾了半天，还是退出不了，最后发现，原来是个bug 阅读详情

对于threadA.joion(timeout)的理解，很多资料上面都说是等待时间超时
但是具体是什么超时？是threadA开始运行的时候就开始计时呢？
我做了一个例子



class Sleeper extends Thread{

    private int duration;

    

    public Sleeper(String name,int sleepTime){

        super(name);

        duration = sleepTime;

        start();

    }

    

    public void run(){

        try{

            sleep(duration);

        }catch(InterruptedException e){

        }

    }

}



class Joiner extends Thread{

    private Sleeper sleeper;

    public Joiner(String name,Sleeper sleeper){

        super(name);

        this.sleeper = sleeper;

        start();

    }

    public void run(){

        try{

            sleeper.join(5);

        }catch(InterruptedException e){

            System.out.println("time out!!");

        }

        System.out.println(getName()+" join completed");

    }

}



public class Joining{

    public static void main(String[] args){

        Sleeper sleepy = new Sleeper("Sleepy",1500),

                grumpy = new Sleeper("Grumpy",1500);

        Joiner  dopey = new Joiner("Dopey",sleepy),

                doc = new Joiner("Doc",grumpy);

        

    }

}
