Puppet users - Jul 2011 - Node or site.pp for global variables without dynamic lookup

Hi all,

I am working on rewriting my entire puppet environment and try to
''fix'' ''Dynamic lookup'' as it will be
deprecated in some time, but even
after reading quite some docs and on the forum, it''s not really clear
to me.

What I have read so far, is that each variable must be fully-qualified
or parameterized in a class.
As a quick ''fix'' I thought I might just make them all
fully-qualified,
but that doesn''t seem to work within my current setup

This is the way I already had configured my nodes
node ''prodserver.mydomain.com'' inherits node
''prd'' which inherits node
''basenode

node ''prodserver.mydomain.com'' inherits prd {
 ....
} # End node

node prd inherits basenode {
  $gblvar_zone = ''prd''
} # End node

node basenode {
  $gblvar_puppetserver = ''puppet.mydomain.com''
  $gblvar_domain = ''mydomain.com''
  .....
} # End node

Normally I would reference these variables in other classes like "$
{gblvar_zone}", but as this is a Dynamic lookup, I redefined them as
"$
{::gblvar_zone}" or $::gblvar_zone. This however does not work.

If I remove the lines from the node  and put it site.pp
eg: $gblvar_zone = ''prd''
it works fine.

I really love the way I can inherit from nodes and define new or
overrule existing variables.

Is this a bug that $::varx works only from site.pp or is it by design
and do I need to find another way to inherit and overrule variables ??
or can I just put all global variables in site.pp

Regards,
Rene

Node scope is not global scope.  But, more interesting:

I have been experimenting with puppet 2.7.1.
It turns out that parameterized classes can inherit from other 
parameterized classes.
Also, hashes behave well, can be passed as arguments, and can be 
augmented on the fly.
Hashes that act as structures, that can be passed around and modified, 
make puppet
feel like a ''real'' programming language.

See attached.
