创建守护进程线程 [英] Create daemon thread

问题描述

我正在尝试在Windows下创建守护程序线程，但是我不知道我在做什么错.下面的代码充当普通线程:我没有看到"End run"写入控制台.有什么建议吗?

I'm trying to create a daemon thread under Windows, but I have no clue what am I doing wrong. The code below is acting as a normal thread: I don't see "End run" written to the console. Any suggestions?

def start(self):         
    self.isrunning = True        
    self.thread = threading.Thread(name="GPS Data", target=self.thread_run)
    self.thread.setDaemon(True)
    self.thread.run()
    print "End Run"


def thread_run(self):
    while self.isrunning:
        data  = self.readline()
        print(data)

推荐答案

以下内容:

self.thread.run()

应为:

self.thread.start()

否则，将在当前线程的上下文中而不是在新线程的上下文中调用thread_run().

Otherwise, thread_run() is getting called in the context of the current thread, and not in the context of a new thread.

thread_run()函数永远不会返回(因为self.isrunning永远不会更改)，并且代码也永远不会到达print语句.

The thread_run() function never returns (because self.isrunning never changes), and the code never reaches the print statement.
