简单来说,它kill的原理是设置一个flag位,然后线程在执行下一句python语句检测到这个位被设置了之后,就会自行退出,以达到kill的目的。 另外还有一种更容易理解的flag置位的实现方式: classKillableThread(threading.Thread): def__init__(self): threading.Thread.__init__(self) ...
下面是网址:https://stackoverflow.com/questions/323972/is-there-any-way-to-kill-a-thread 开始进入正题: 多线程 首先线程中进行退出的话,我们经常会使用一种方式:子线程执行的循环条件设置一个条件,当我们需要退出子线程的时候,将该条件置位,这个时候子线程会主动退出,但是当子线程处于阻塞情况下,没有在循环...
然而,还有一些使用场景中你真的需要kill掉一个线程:比如,当你封装了一个外部库,但是这个外部库在长时间调用,因此你想中断这个过程。 解决方案 ·貳 接下来的方案是允许在python线程里面raise一个Exception(当然是有一些限制的)。 def_async_raise(tid,exctype):'''Raises an exception in the threads with id ...
You must terminate a thread from the outside, but Python doesn’t let one thread brutally kill another, so you need a controlled-termination idiom. Solution A frequently asked question is: How do I kill a thread? The answer is: You don’t. Instead, you kindly ask it to go away. Th...
