Re: [Puppet Users] Quick question about types/providers

2015-03-02 Thread Peter Berghold
Turned out restarting the puppet master was the solution.  Drove me insane
for a while, but now all but a couple of things have started to work.  I've
posted about one of them in a separate thread.

 Generally, I'd like to second John's general advice: Do restart your
 Puppet processes to make sure that changes to your Ruby code take effect.

 Yes, this is basically a getter/setter pair.

 However, the idempotency is implemented closer to the type layer. The
 transaction code will check whether properties are out of sync, and
 invoke the provider = methods to take action if necessary.

 On this higher level, your assertion should hold true. But I'm not sure
 if that's what you were asking.

[Puppet Users] Quick question about types/providers

2015-02-27 Thread Peter Berghold
Using the example of the file provider that is bundled with puppet here is
a sniglet of code that I've zoomed in on:

 def mode
if stat = resource.stat
  return (stat.mode  00).to_s(8)
else
  return :absent
end
  end

  def mode=(value)
begin
  File.chmod(value.to_i(8), resource[:path])
rescue = detail
  error = Puppet::Error.new(failed to set mode #{mode} on
#{resource[:path]}: #{detail.message})
  error.set_backtrace detail.backtrace
  raise error
end
  end

can I guess that the first def mod is what is referred to as a getter and
second is a setter?Can I stretch that inference to say that if the
value being passed to the setter is the same as what the getter is seeing
it won't be set again?

Re: [Puppet Users] Quick question about types/providers

2015-02-27 Thread Peter Berghold
So, I wrote my type and its provider.

Have a bunch of params and of course the first one I try to use
  newparam(:ipv4listen) do
desc the ipv4listen param
  end

doesn't seem to be seen by the Puppet infrastructure.

Error: Could not retrieve catalog from remote server: Error 400 on SERVER:
Invalid parameter ipv4listen on Bindconfigure[MOB_OAM_SVC] at
/etc/puppet/environments/POC/modules/multibind/manifests/mob_oam_svc.pp:22
on node CLIENT
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

So obviously I'm missing something here...

Thoughts?   Wish there was an equivalent to Perl's Data::Dumper that would
let me see what parameters Puppet things are defined.
