python之在 multiprocessing.Process() 中调用 subprocess.Popen() 时管道损坏

我在从 multiprocessing.Process() 中进行 shell 调用时遇到问题。该错误似乎来自 Git，但我无法弄清楚为什么它只发生在 multiprocessing.Process() 中。请注意，下面是一个演示正在发生的事情的示例......在实际代码中，Process() 中还有很多事情......但我正在使用 Popen 进行 shell 调用作为它的一部分:

#!/usr/bin/python 
 
import os 
import shutil 
from multiprocessing import Process 
from subprocess import Popen 
 
def run(): 
    cmd_args = ['git', 'clone', 'git@github.com:derks/test.git', 'test-repo-checkout'] 
    res = Popen(cmd_args) 
    res.wait() 
 
# clean 
if os.path.exists('./test-repo-checkout'): 
    shutil.rmtree('./test-repo-checkout') 
 
print "\n--- this doesnt work" 
process = Process(target=run) 
process.start() 
process.join() 
 
print "\n--- this does work" 
run() 

结果是:

$ python test.py 
 
--- this doesnt work 
Cloning into test-repo-checkout... 
Warning: untrusted X11 forwarding setup failed: xauth key data not generated 
Warning: No xauth data; using fake authentication data for X11 forwarding. 
fatal: write error: Broken pipe 
 
--- this does work 
Cloning into test-repo-checkout... 
Warning: untrusted X11 forwarding setup failed: xauth key data not generated 
Warning: No xauth data; using fake authentication data for X11 forwarding.

任何帮助都会很棒...我对多处理模块还是陌生的，直到现在才遇到任何问题。

请您参考如下方法:

Hrm，我刚刚意识到我在 Python 2.6.1 上运行....在 2.6.4 上运行相同的示例没有有同样的问题。看起来像是已在 Python 中修复的错误。
