Puppet users - Aug 2013 - Trouble with ENC and static.pp : enabling ENC fails to find node even with default node in site.pp

I''m having some trouble with getting an ENC to work alongside site.pp:

Even with a ''default'' node definition, and an ENC that only
returns 0,
regardless of input, consistently results in a ''cannot find
node'' error.
 I''m wondering what I''ve missed here.

I''ve tried to reduce everything to a ''base case'': and
I''m running 3.2.4 on
the client and master both:

Here''s what I''m trying:

here''s my static node definition:

*site.pp:*
*node default {*
* notify { "static node definition": }*
*
*
*}*

and my puppet.conf without any node definition:

*puppet.conf*
*[master]*
*    node_terminus = plain*

works beautifully:

*[root@vacsld01target ~]# /usr/bin/puppet agent --onetime --daemonize 
--verbose --test*
*Info: Retrieving plugin*
*<snip>*
*Info: Caching catalog for vacsld01target.oss.central1.com*
*Info: Applying configuration version ''1377125492''*
*Notice: static node definition*
*Notice: /Stage[main]//Node[default]/Notify[static node 
definition]/message: defined ''message'' as ''static
node definition''*
*Notice: Finished catalog run in 0.05 seconds*


If I enable an ENC that only returns 0 regardless of input with the same 
site.pp configuration:

*puppet.conf*
[master]
*    node_terminus = exec*
*    external_nodes = /var/lib/puppet/null-nodes.py*
*    reports = store*
*    reportdir = /var/lib/puppet/reports*


*[root@vacslp01pmaster manifests]# cat /var/lib/puppet/null-nodes.py*
*#!/usr/bin/python*
*import sys*
*sys.exit(0)*

running the ENC by hand as user puppet:

*[root@vacslp01pmaster manifests]# sudo -u puppet 
/var/lib/puppet/null-nodes.py ; echo $?*
*0*


*restart puppetmaster*
*rerun the client*
*
*
*[root@vacsld01target ~]# /usr/bin/puppet agent --onetime --daemonize --test
*

Ok, I''ve got a workaround.  if I return some valid YAML in addition to
the
0 return value, everything works like poptarts:

*        null_obj = { ''vars'' : { ''emptyvar'':
''0''}}*
*        print yaml.dump(null_obj, Dumper = yaml.SafeDumper)*
*        exit(0)*

then the node definitions (including default node definitions) are found in 
site.pp:


*Notice: vacsld01target node definition*
*Notice: 
/Stage[main]//Node[vacsld01target.oss.central1.com]/Notify[vacsld01target 
node definition]/message: defined ''message'' as
''vacsld01target node
definition''*
*Notice: Finished catalog run in 0.24 seconds*
