Summary: subprocess on Windows: extra windows
Initial Comment:
My understanding was that subprocess.py was supposed to be
backwards compatible with at least Python 2.3 if not 2.2. Wanting
subprocess and backwards compatibility, I grabbed the subprocess.py
from 2.4b1, changed the import if so that win32api was used (since I
had no _subprocess library!) and found several problems, of which
this is is the mildes:
when using subprocess.Popen on Windows I get one or more windows
called C:\WINNT\system32\CMD.EXE popping up. Sometimes they
stick around, other times they are only around for a short time. Note
that I don't see this probem using os.popen3 (on the
other hand, os.popen3 has inferior error handling).
The following code is one example:
from subprocess import *
Popen("ds9 -title foo", shell=True, cwd="C:\Program Files\ds9\")
