Xen devel - Sep 2006 - Question about ACMError

Hi all,

Could you teach me about the behavior of xm commands when 
''ACMError'' occurred?

I am testing the behavior of xm commands with wrong arguments. 
When I tested xm commands related to security (xm *label/*policy), 
I found that some of them.
 - return 0,
 - show ACMError''s Traceback messages.

Are these results specifications or bugs?

Example:
# xm cfgbootpolicy xyz
ACMError: Illegal policy name ''xyz''
# echo $?
0
# xm addlabel xyz dom acm-test1.conf
ACMError: No active policy. Policy must be specified in command line.
Traceback (most recent call last):
  File "//usr/lib/python/xen/xm/addlabel.py", line 129, in main
    security.err("No active policy. Policy must be specified in command
line.")
ACMError: ''No active policy. Policy must be specified in command
line.''
# echo $?
0

Best regards,
 Kan

Hi Kan,

I will fix this :-)

Catching the exception is ok, but exiting without error code is not.

Thanks!
Reiner
