Question

I have a service that spawns threads.
The threads are started by providing a target function.
It would appear that the thread doesn t "die" when the function ends. I know this because the thread makes some SSH connections with Paramiko (via Fabric), and if I do an lsof I see the SSH connections are still active after the function completes.
How can I make sure that a thread dies when its target function completes?

这方面的一个例子是,我正在与以下方面合作:

from time import sleep
from threading import Thread
from fabric.api import run, settings

def thread_func(host):
    with settings(host_string=host):
        run( ls -lht /tmp )

def spawn_thread(host):
    t = Thread(
        target=thread_func,
        args=(host,)
    )
    t.start()

spawn_thread( node1.example.com )
while True:
    sleep(1)

如果我在另一个终点站运行sudo lsof grep ssh<>>,而上述代码在限定的舱面一号内,则在Iknow之后仍可看到以下内容,即表面不应再存在:

Answer 1

你们是否相信你的布局,只是在指挥期间才这样做。也就是说,它应当做到等同。

背景

这一指挥线将打开一条遥远的炮弹,以控制步枪——直升机的指挥,然后关闭。

但是,我怀疑法布里图书馆可能做到:

东道国

host$ ls -lht /tmp . .

当然,这并不提供真实的情况,但有一些不同的选择,可以保持一种没有互动的连接。在某些情况下,这样做是可取的(例如,如果你在同一个东道国拥有许多指挥权,那么这种技术将重复现有的会议,而不是每次开新会议。查阅文件,以提出论据,使这种会议能够或能够分开进行。
