Here is a current snapshot of the bug.

Category: Windows
Status: Open

Summary: [windows] os.popen doens't kill subprocess when interrupted

Details: Hi, in the following script I liked to make an interface to the
contig program(http://www.sysinternals.com)

As the popen invocation can be a long time process (since it walks
recursively trough directories) I press CTRL-C sometimes and the contig
continues to run.

I use Python 2.0 (BeOpen version) under WinNT 4.0(SP 4)

Maybe I made a mistake in the following script ?

-------------------------------------------------

#! /usr/bin/env python

import sys;
import os;
import re;

content = ""

mm = re.compile("Processing (.+)?:\nFragments: (\d+)?");

output = os.popen("contig -a -s *.*");

while(1):
  line = output.readline();
	
  if line == '':
    break
	
    content += line;


status = output.close()

if status:
  print("Error contig : "+`status`+"("+os.strerror(status)+")");
  sys.exit(12);

print mm.findall(content)

Comment:
Poor Mark.  I assign anything with "popen + Windows" to you, because you're
the only one who ever makes progress on them <wink>.  Offhand, I can't see
how Ctrl+C directed at Python *could* interrupt a spawned process.
