[Pythonmac-SIG] py2app run errors

[William Kyngesburye]

I have a python script that sets a couple environment vars and runs a  
shell script in a Terminal window.  It works when run from a Terminal  
with 'python doshell.py'.  But when packaged into an app with py2app  
I get errors.

Here's a simplified version (doshell.py):

#!/usr/bin/env python

import sys
import os

base = os.path.dirname(sys.argv[0])

# options used by myshell.sh (can't use args)
os.environ['STARTBASE'] = base
os.environ['MYOPTION'] = 'shelloption'

shellrun = base + '/myshell.sh'

os.execlp('open', 'open', '-a', 'Terminal.app', shellrun)

# continue doing python stuff...


The error I get:

Traceback (most recent call last):
   File "/Users/Shared/src/myshell/dist/doshell.app/Contents/ 
Resources/__boot__.py", line 137, in ?
     _run('doshell.py')

2006-08-10 12:11:34.919 CommandDroplet[409] doshell Error
An unexpected error has occurred during execution of the main script


I've built the app with the semi_standalone option, and the  
myshell.sh script is also installed in the app with the resources  
option in py2app.  Built completely standalone, same error, except  
that the os.py lines have no path.

I tried using spawnlp instead, but in the Terminal AND in the py2app  
application I get the error:

RegisterProcess failed (error = -50)


I'm just getting my feet wet with Python, so I wouldn't be surprised  
if I did something wrong here.  Maybe there's a better way to run the  
shell script in a Terminal.  Maybe something is wrong with argv[0]  
when run from the app so the path to run the shell script is wrong.   
The error isn't very helpful.
