python - 停止tornado.TCPServer而不等待连接关闭

Question

tornado.tcpserver.TCPServer.stop 的文档说:

Requests currently in progress may still continue after the server is stopped

但是，为了测试稳健性，我想模拟服务器的完全崩溃。

有没有一种首选方法可以突然终止tornado.TCPServer？特别是，我想不优雅地终止所有打开的套接字。

编辑

所以我认为 stop 不会完全终止现有连接。以下代码打印 1, 2

from tornado import gen
from tornado.ioloop import IOLoop
from tornado.tcpserver import TCPServer
from tornado.tcpclient import TCPClient

port = 9000

class Server(TCPServer):
    @gen.coroutine
    def handle_stream(self, stream, address):
        while True:
            bytes = yield stream.read_bytes(5)
            yield stream.write(bytes)

server = Server()
server.listen(port)

@gen.coroutine
def client():
    client = TCPClient()
    stream = yield client.connect('127.0.0.1', port)
    yield stream.write(b'Hello')
    result = yield stream.read_bytes(5)
    assert result == b'Hello'
    print(1)

    server.stop()

    yield stream.write(b'Hello')
    result = yield stream.read_bytes(5)
    assert result == b'Hello'
    print(2)

IOLoop.current().run_sync(client)

Answer 1

TCPServer.stop 正是您想要的；您引用的评论是一个警告，表明 TCPServer 不会尝试正常关闭。
