Python可以杀死继续运行的子进程吗？ [英] Can Python kill a child process that keeps on running?

问题描述

假设我们用Popen生成子进程。我正在考虑一个

可执行文件，就像编译的C程序一样。

假设它应该运行一分钟，但它只是继续运行

并继续。 Python有没有办法杀死它？


这不是假设的;我现在正在这样做，并且它的工作非常好，但是我希望能够处理这种连续状态。我是

使用Windows 2000，但我希望我的程序可以移植到linux。


谢谢

在linux上它很容易做到，只需设置报警信号。在windows上

使用python.org

发布你不能做到这一点并不是那么微不足道，你需要使用win32在低级别的C API中查找

扩展名或ctypes。 AFAIK扭曲包< http://twistedmatrix.com>

有一些代码可以帮助你。另请参阅buildbot来源

< http://buildbot.sf.net>使用扭曲。 Buildbot与你有相同的问题，它需要杀死逃跑或无响应

进程。

这是坏消息。不管怎么说，还是要谢谢你;坏消息比没有新闻好。

但是，请注意，taht ctypes计划是2.5

发行版的一部分，所以虽然可能没有是一个独立于平台的方式来实现你的目标，你可以在没有外部

扩展的情况下实现你的目标。

Suppose we spawn a child process with Popen. I''m thinking of an
executable file, like a compiled C program.
Suppose it is supposed to run for one minute, but it just keeps going
and going. Does Python have any way to kill it?

This is not hypothetical; I''m doing it now, and it''s working pretty
well, but I would like to be able to handle this run-on condition. I''m
using Windows 2000, but I want my program to be portable to linux.

Thanks

On linux it''s pretty easy to do, just setup alarm signal. On windows
it''s not so trivial to the point you cannot do it using python.org
distribution, you will need to poke in low level C API using win32
extensions or ctypes. AFAIK twisted package <http://twistedmatrix.com>
has some code to help you. Also take a look at buildbot sources
<http://buildbot.sf.net> that uses twisted. Buildbot has the same
problem as you have, it needs to kill run away or non-responding
processes.

That is bad news. Thanks anyway; bad news is better than no news.

Note, however, taht ctypes is planned to be a part of the 2.5
distribution, so while there may not be a platform-independent way to
achieve your goals you will at leats be able to do so without external
extensions.
