First lets start with a suggestion. there a lot function that return a
class, mabye a new function:
- LISA_CLUSTER expression => getenv_class("LISA");
Which set the class LISA_CLUSTER if the variable is defined. We now use
getenv and strcmp to do this
I am reading a lot of documentation but i am a bit lost. You must read
carefully what is for the community edition and what is for the other
versions. I find this a bit confusing. Baer in mind i must get acquainted
with the new syntax.
I am trying to switch from cfengine2 to cfengine3. We make use of the
PrepModule to set some useful GLOBAL classes with the aid of a script. Just
print/echo +<class> to stdout. Can this be accomplished with cfengine3.
I am using cfengine community edition 3.0.4 and i get this error/warning.
But the class can not be true, because the environent variable is set.
{{{
!! Redefinition of a constant variable "CLUSTER"
Promise (version 1.0.1) belongs to bundle 'g' in file
'/var/lib/cfengine3/inputs/promises.cf' near line 51
!! Redefinition of a constant variable "cluster_file"
Promise (version 1.0.1) belongs to bundle 'g' in file
'/var/lib/cfengine3/inputs/promises.cf' near line 52
}}}
the promises.cf file:
{{{
bundle common g
{
vars:
"lisa" string => getenv("LISA_CLUSTER","1");
LISA_CLUSTER::
"CLUSTER" string => "LISA";
"cluster_file" string => "lisa.cf";
!LISA_CLUSTER::
"CLUSTER" string => "NOT LISA";
"cluster_file" string => "common.cf";
classes:
"LISA_CLUSTER" expression => strcmp("$(lisa)","1");
}
This is due the fact that vars is evaluated sooner the class is set. What i
want is to import files based on a class that is not known. Or is there a
better syntax for cf3 that i did not find.
