I tried writing a type to handle a cobbler repository (because it is the
first thing cobbler wants to see if you start to define a system).
However, I have two problems:
1) (this is a theoretical question for now)
If I understand types (for now without providers) correctly, if I have a
property ensure, it needs a "def retrieve" which returns the current
state of the resource. These returned states should match the "newvalue"
definitions I provide in the source. So if I have
newvalue :present
newvalue :absent
newvalue :insync
with accompanying code, the following should work for retrieve:
def retrieve
ret=`cobbler repo list | \
grep -qE '(^|[[:space:]])#{resource[:name]}([[:space:]]|$)';\
echo $?`
if ( not ret == 0)
:absent
else
if insync?
:insync
else
:present
end
end
end
(As long as I have a working insync? definition)
Is this correct so far? If I defined insync? inside the same newproperty
(:ensure in this case), should I access it as done above, or should I
use "self.insync?" or something else?
2)
I defined retrieve as listed above (full source of the cobbler_repo.rb
is at http://mail.incase.de/cobbler_repo.rb, it surely isn't the best
code I ever wrote, but I can't see why it shouldn't work) and I get:
Tue Oct 07 15:14:02 +0200 2008
//Node[testinst01]/cobbler/Cobbler_repo[CentOS5_i386] (err): Failed to
retrieve current state of resource: wrong number of arguments (1 for 0)
Any hint what I did wrong? What passes one argument to which
function/method and what do I have to do to resolve this. I'm really at
a loss here.
regards,
Sven
