Hello,
I'm running into a strange situation with getting incorrect
returncodes / exit status from python subprocess.call. I'm using a
python script (runtime 2.6.1 on windows) to automate the deploy of
java applications to glassfish application server. Below is an example
of using a subprocess call to test the success / failure of the
glassfish CLI tool "asadmin"
Example.py:
----------------------
import sys
from subprocess import *
try:
retcode = call("c:/glassfish/bin/asadmin.bat " + "list-system-
properties --host mydomain --port 4848 --user admin server-01",
shell=True)
if retcode < 0:
print >>sys.stderr, "Child was terminated by signal", -retcode
else:
print >>sys.stderr, "Child returned", retcode
except OSError, e:
print >>sys.stderr, "Execution failed:", e
----------------------
However, when I execute it, it gets the same returncode whether it
fails or succeeds (0).

When I execute this manually from the cmd.exe and I check the
%errorlevel% it returns the correct levels:

-------------------------------------
I'm guessing that returncode isn't the same thing as exit status? Is
there a way to get exit status using a subprocess function instead of
returncode? Is this the right way to go about this?
Thanks for any direction / advice you can provide.
Andrew
