Puppet users - May 2011 - The quantum effect when loading classes

Can anyone comment / expand upon
http://www.nico.schottelius.org/blog/puppet-sometimes-loads-a-class/

I am experiencing a case which may be related. We have an ENC, and recently
on our twice daily noop runs from cron, puppet has reported some servers
aren''t in sync because they do not have a certain module/class
(dns_server)
even though they are not subscribed to the dns_server module in the ENC

I can''t reproduce it from the command line (yay), so am stumped
debugging
the issue, however, our dns_server module is not standard, and is probably
causing the screw up

% cat modules/dns_server/manifests/init.pp
import "*.pp"
include dns_server

% ls -l modules/dns_server/manifests
total 56
-rw-r--r--   1 warbjoh  unxadmin   22296 Mar 15 18:38 dns_server.pp
-rw-r--r--   1 warbjoh  unxadmin     489 Mar 15 18:38 init.pp

I have modified the module by renaming dns_server.pp to init.pp and hence
removing the "import *.pp"

I am now waiting to see if that has fixed the issue, but if it has (I
suspect it will), why and how does this happen?

Thanks

John

Hi,

You should include the version number with your questions so we can narrow down
answers :)

First thing I would do is grep through manifest and look for any calls to the
classes in your module.

Also the syntax looks a bit odd to me. No doubt works but it is not the way
puppet recommends. I would put the class inside your init.pp (like you said
you''ve done now).

You can put some notifies in your module and see if you can get more debugging
info.

Apart from that I have nothing else to offer I''m afraid.

Cheers,
Den

You should avoid import in favor of include like this:

# modules/dns_server/manifests/init.pp
class dns_server {
  # actual contents of your dns_server class.
}

and then your ENC or site.pp just does "include dns_server".

Hi, 

Bit hard to make any real comment on the blog because we don''t have a
copy of the manifest (or test case), the version that exhibits the behavior or a
log to show what is occurring. Nor has he(or she) filed a bug report to my
knowledge.

If I experienced that sort of behaviour that''s what I''d do.
I''ve not seen that particular behaviour.

Cheers,
Den
