为什么asyncio的事件循环会抑制Windows上的KeyboardInterrupt?

问题描述

我有一个非常小的测试程序，除了执行asyncio事件循环外，什么也没有做:

I have this really small test program which does nothing apart from a executing an asyncio event loop:

import asyncio
asyncio.get_event_loop().run_forever()

当我在Linux上运行该程序并按 + 时，该程序将正确终止，并出现KeyboardInterrupt异常.在Windows上，按 + 不会执行任何操作(已在Python 3.4.2中进行了测试). time.sleep()的简单无限循环即使在Windows上也可以正确地提高KeyboardInterrupt:

When I run this program on Linux and press +, the program will terminate correctly with a KeyboardInterrupt exception. On Windows pressing + does nothing (tested with Python 3.4.2). A simple inifinite loop with time.sleep() raises the KeyboardInterrupt correctly even on Windows:

import time
while True:
    time.sleep(3600)

为什么异步事件循环会抑制Windows上的KeyboardInterrupt?

Why does the asyncio's event loop suppress the KeyboardInterrupt on Windows?

推荐答案

确定是一个错误.
