Re: ReturnsZero(): command does not return zero. Is classcreatedwith value of false?

[Mark . Burgess]

The following works fine for me:


control:

actionsequence = ( editfiles )

classes:

  xxx = ( ReturnsZero(/bin/true) )
  yyy = ( ReturnsZero(/bin/false) )

alerts:

 xxx::

   "true worked!!"

 yyy::

   "false didn't work!!"


i.e. it prints one message "true worked".

Can someone provide more info about what has changed
in cfengine here? I cannot see any differences and the
code of 2.0.7 and 2.1.5 look the same at first glance.
