exception hook的执行流程大致如下: 如图所示,在hook过程中需要多次对hook点指令和hook点的下一条指令进行修改,由此造成在执行效率上的损耗。 首先我们需要将hook点指令替换为一条不合法的异常指令,当程序执行到该位置时进程会接收到信号SIGILL(illegal instruction),然后进入到我们注册的SIgnal Handler中,在信号处理函里...

Errorinsys.excepthook:Original exception was: 想了一下,原来是子线程还没退出,主线程就退出了,需要确保主线程等待所有子线程退出后再退出,如果主线程比子线程早结束,子线程就会中断,抛出这个异常。简单加个sleep,就没有报错了,当然,比较好的方法是给每个线程都加了一把锁,直到线程运行结束,再释放这个锁。同时在...
