Hello! I'm trying do write a method, which will then proceed differently based on parameter passed to it. The problem is that I cannot define class based on string in variable, BUT, which is funny but confusing, I CAN use this variable in editfiles section without problems! It seems, that arguments passed to methods are created AFTER classes section was evaluated. Any ideas, what to do about that? Passing class to method possibly would solve my problem of course, but then whole idea of using methods in my system (I'd like to use them, because they could very clearly isolate some components - ie.: to play with Kerberos you have one method, and you can play with it only via parameters defined by desiger of module). Of course I can use few methods as well, but still this strange behaviour of cfengine is at best confusing...
My configuration looks like this:
cfagent.conf:
---
control:
IfElapsed = ( 0 )
actionsequence = ( methods )
methods:
TestMethod(doit)
action=method.cfm
returnvars=null
returnclasses=null
server=localhost
---
method.cfm:
---
control:
MethodName = ( TestMethod )
MethodParameters = ( arg1 )
IfElapsed = ( 0 )
actionsequence = ( editfiles )
classes:
ParameterClass = ( Regcmp(.*doit.*,${arg1}) )
editfiles:
any::
{ /tmp/somefile
AutoCreate
EmptyEntireFilePlease
InsertLine "var1 = ${arg1}"
}
ParameterClass::
{ /tmp/somefile2
AutoCreate
AppendIfNoSuchLine "Class was defined"
}
alerts:
ReturnVariables(null)
ReturnClasses(null)
---
And /tmp/somefiles2 is never created. But if I define variable locally
in control section of method, and assign to in string "doit" (ie.: arg1
= ( doit ) ) everything works like it suppose to work.
Here is a diagnostic output from cfengine:
