杀死孩子 [英] Killing children

问题描述

我正在编写一个必须生成某些进程的应用程序然后

以后再杀掉它们。

他们正在运行时，它不需要说话或听他们，但有停止和启动按钮和停止

按钮应该停止一切通过开始按钮开始。


在Linux上有很多方法可以做到这一点，但这个项目必须在cygwin下运行
。到目前为止，我在cygwin下完成的唯一工作就是做一个os.system来启动这个过程然后

解析ps输出并使用os.kill来查找ps b / b
找到的进程。这在许多方面都不尽如人意。


我无法让os.spawnl正确启动进程。

我正在使用pexpect，与测试程序一起工作得很好，但不需要生成需要生成的实际流程的
。我做了一点点

玩过程模块，但没有让它工作正常。


有没有人有更好的主意？

这在某些情况下是成功的：


if sys.platform ==''win32''：

def _kill（pid，sig）：

'' ''''pid实际上是句柄，但这就是os.spawn *返回的内容

Win32'''''

导入win32api

win32api.TerminateProcess（pid，0）#sign sig，0返回

进程代码

import os

os。 kill = _kill

del _kill

它需要win32api，我不知道这一切将如何工作

cygwin（我不要用）。基本上它允许你以独立于平台的方式使用os.kill（）

（前提是你只关心
Linux和Windows NT / XP / 2K ;-)。

嗨劳拉，


多么糟糕的主题！ ;-)


我有时会使用os.system和pskill
http://www.sysinternals.com/ntw2k/freeware/pskill.shtml - 这应该是

做你想要的。


我从一些产卵变种IIRC获得了我的pid。这应该比通过名称杀死或解析ps输出更可靠（因为你可能

如果有多个进程有相同的话，就会杀死错误的进程

name）。


你的产卵究竟什么不合适？你可以发布你正在使用的产生

电话吗？


干杯，

Stefan

win32api似乎没有出现在cygwin上。

I''m writing an application that has to spawn some processes and then
kill them later. It doesn''t need to talk or listen to them while
they''re running, but there are stop and start buttons and the stop
button should stop everything that gets started by the start button.

There are lots of ways to do this on Linux, but this project has to
run under cygwin. So far, the only thing I''ve gotten to work at all
under cygwin is doing an ''os.system'' to start the process and then
parsing the "ps" output and using os.kill on the processes that ps
finds. This is unsatisfactory in a number of ways.

I have been unable to get os.spawnl to start the processes correctly.
I was using pexpect, which worked fine with test programs, but not
with the actual processes that need to be spawned. I did a little bit
of playing with the "process" module but didn''t get it working right.

Does anyone have a better idea?

This has been successful in some cases:

if sys.platform == ''win32'':
def _kill(pid, sig):
''''''pid is actually handle, but that''s what os.spawn* returns on
Win32''''''
import win32api
win32api.TerminateProcess(pid, 0) # ignore sig, 0 is return
code for process
import os
os.kill = _kill
del _kill
It requires win32api, and I don''t know how that all will work with
cygwin (which I don''t use). Basically it lets you use os.kill()
in a platform-independent fashion (provided you care only about
Linux and Windows NT/XP/2K ;-).

Hi Laura,

what a terrible subject line! ;-)

I sometimes use os.system with pskill from
http://www.sysinternals.com/ntw2k/freeware/pskill.shtml - this should
do what you want.

I do get my pid from some spawn-variant, IIRC. This should be more
reliable than killing by name or parsing ps output (since you might
kill the wrong process if there are multiple processes with the same
name).

What exactly doesn''t work with your spawning? Could you post the spawn
call you''re using?

Cheers,
Stefan

win32api doesn''t seem to be there on cygwin.
