command string good in subprocess.Popen(string) fails inprocess.Process(string)

[Earl Eiland]

The command string consists of "filename.exe instruction1 instruction2
...." It works in subprocess, but in process, returns the error "can't
find the file instruction1".

How do I pass command line instructions in process.Process? I tried a
list ['filename.exe', 'instruction1 instruction2 ...'] with the same
result.

If you're wondering why I'm switching, it's because I'm working with a
poorly behaved 3rd party program that causes a severe memory leak, and I
need the process modules timed "wait(n)" method (or write my own).

Where are you getting this "process" module from? It's not standard:

c:\>python
Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)] on win32

import process

Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named process

from Trent Mick tr****@ActiveState.com:
"You might be able to use or borrow code from my process.py module.
process.py is very similar to Python 2.4's subprocess. It provides a
ProcessOpen class (similar to subprocess' Popen). A ProcessOpen instance
has wait() and kill() methods that work fine on Windows. Under the hood
they are using the Win32 API WaitForSingleObject() and
TerminateProcess() functions."

Few here have ever heard of it, I suspect. Maybe you should ask Trent
for help?

The docs (in the form of the Powerpoint presentation on his site, which
I'm reading using OpenOffice) suggest maybe you should be using
['filename.exe', 'instruction1', 'instruction2', ...] instead...
