[python-win32] win32 pipes and CreateProcess

[Drew Whitehouse]

Hi,

I'm investigating some problems I'm having with win32 process creation
and in the course of investigating the matter I've noticed this
behavior ...

If you modify the example in win32/demos/pipes/runproc.py so that the test is

if __name__ == '__main__':

    import time
    while 1:
        p = Process()
        exe = win32api.GetModuleFileName(0)
        p.run(exe + ' cat.py')
        time.sleep(1)

It crashes with ....

$ python runproc.py
Read on stdout:  'hmmmmm\r\n'
Read on stderr:  'Blah...'
Read on stdout:  'hmmmmm\r\n'
Read on stderr:  'Blah...'
Traceback (most recent call last):
  File "runproc.py", line 111, in ?
    time.sleep(1)
pywintypes.api_error: (6, 'CloseHandle', 'The handle is invalid.')

Any ideas ?

-Drew
