 $root_passwd  only has value if someone has defined it. So, i.e:
 
 nodes.pp 
 nodea {

 nodeb {

Maybe its just a typo in your mail, but you set $root_passwd and test
$root_password.

 When I run the client in nodeb, and add a notify of root_password, I see
 that nodeb's root_password has a value and it's serviceA!?!?

This can happen when you have set the var in top scope (nodes.pp
directly or in site.pp) or you have some missing bracket somewhere and
your nodedefinition still works magically while scope is totally mixed up
(happened to me a few times)

that was what happened. Someone defined it at node's top, and it
became a global defined var.

[Puppet Users] variables with no value

2010-12-10 Thread Arnau Bria 
Hi all,

We'd like to share a class, and do something like:

class common_defaults {
[...]
 user { 'root':
   ensure  = present,
   password= $root_password ? {
  'serviceA'= 'passwdA',
  default   = 'passwdB',
 },
[...]
}

$root_passwd  only has value if someone has defined it. So, i.e:

nodes.pp 
nodea {
$root_passwd=serviceA
include common_defaults
}

nodeb {
include common_defaults
}


so, we'd like nodea to has passwdA and nodeb to have the default value
passwdB. I've tried with default and '' empty var, but I does not works
neither.

When I run the client in nodeb, and add a notify of root_password, I see
that nodeb's root_password has a value and it's serviceA!?!?

I'm quite lost here, I've been reading variable scope section in
puppet's doc, but it talks about class inheritance, not class
including. I don't understand why the var has a value, I've not found
any ref about value of not defined varibales.

Could anyone give a hand on this?

TIA,
Arnau

Hi,

could you be a little less cryptic about the node definitions? (I
understand there may be privacy issues, but the above is censored too
drastically.)

Is it possible they overlap in some way?

Cheers,
Felix

 Hi,
Hi,

Each node has its own classes, and they share 3, but only one
(that one) has a variable. So, each node have other includes,
but they don't overlap, diff services, diff classes.

We could simply as my previously example.
is the selctor correct?

   password= $root_password ? {
  'serviceA'= 'passwdA',
  default   = 'passwdB',
 },

I mean, the default has any sense? if not default but ''? 
because if that selcetor should work, the problem is somewhere else and
we must carefully check our includes.

The selector looks fine. You stated that your notify showed that nodeB
uses a variable value it should not use.

Break the manifests down to the most simple subset that shows this
misbehaviour, then post that. (But you will probably stumble upon an
error in the process, anyway.)

Ok.

Yep. But I thought that it could be caused by the selector, cause it's
my first one where default covers non-defined var case.

Yep, I'll try the simplest example in my test server and come back.

Many thanks for your reply.
