Hello,
The more complicated my puppet scripts gets, the more ordering issue i meet.
Here is a simple thing:
I use a default backup policy for the nodes in my backup classe and then, in
the node i try to override the defined
default but even if they are done one after the other i got an error to say that
the override is triggered before the
default:
include backup
Backupset[''myserver-backup''] {
inclure => "[''/etc'',
''/usr/local/etc'']",
exclure => "[''/tmp'',
''/var/tmp'', ''/var/log'',
''/proc'']",
retention => ''4'',
rsyncversion => ''29+''
}
and i got:
err: Could not retrieve configuration: Parameter exclure is already set on
Backupset[myserver-backup] by myserver at
/etc/puppet/manifests/./os/vpsv2.pp:43
i have to create a new class for each node that inherits the backup class where
i override the Backupset and this just
feel strange to me as the include should setup the Backupset and then i should
be able to override it (this is what
"seems"(tm) logical to me ) :)
how can this ressource be set with the override syntax if the overrided one
does not exist yet ? I would have
expected an error if puppet see the ressources in this order but not a message
saying the ressource is allready having
the parameter xxx setup :)
i had the same issue of ordering things with the tag() function and i wanted
to know how any of you solve those
issues about ordering things in puppet ?

from the test i made it seems that overriding a defined type that contain
virtual ressource does not ovveride them.
I have
define backupset( $periode=''1'',
$rsyncversion=''29+'',
$retention=''4'',
$utilisateurbackup=''aqbackup'',
$blackout=''1-6'',
$backupshare="[''/'']",
$mainhostname=''none'',
$inclure="[''/etc'',
''/usr/local/etc'']",
$exclure = "[''/tmp'',
''/var/tmp'', ''/var/log'',
''/proc'',
''/dev'',''/home/*/.spamassassin/bayes*'']",
$administrateur= ''me'',
$utilisateurs='' '' ) {
$sdl = "
"
@@file { "/etc/BackupPC/serveurs/$fqdn":
content => "$fqdn 0
$administrateur $utilisateurs $sdl",
owner => backuppc,
group => www-data,
mode => 640
}
}
and if i overide $utilisateurs with
Backupset[''blah''] {
utilisateurs => ''otherman''
}
it does not seem to work . If i replace by a template with the very same
content (in erb syntax) it works.
@@file { "/etc/BackupPC/serveurs/$fqdn":
content =>
template("/var/puppet/templates/backuphost.pl"),
owner => backuppc,
group => www-data,
mode => 640
}
works ok.

If the backupset instance is defined in the ''backup'' class, then you shouldn''t be able to override it unless you''re in a subclass of that class.> how can this ressource be set with the override syntax if the > overrided one does not exist yet ? I would have expected an error > if puppet see the ressources in this order but not a message saying > the ressource is allready having the parameter xxx setup :)Overrides are very late-binding; they only get evaluated when the resource is evaluated as a defined type or when the resource is about to get sent to the client. It''s done this way specifically to avoid ordering issues.> i had the same issue of ordering things with the tag() function and > i wanted to know how any of you solve those issues about ordering > things in puppet ?Tags are explicitly file-ordered, which I agree is a bug but I have no idea how to fix it. I expect the closest we''ll come to solving this is the node-mapping application discussed on the dev list, which will provide a list of tags that will be set before the configuration is parsed at all. I have no timeline on getting this done, though. -- Sabbagh''s Second Law: The biggest problem with communication is the illusion that it has occurred. --------------------------------------------------------------------- Luke Kanies | http://reductivelabs.com | http://madstop.com

You''ve got a definition that creates an exported resource. You''re saying you cannot override that definition; can you define "does not seem to work" here? Do you get an error, or does it just fail? Can you reproduce the problem using virtual resources in a simple configuration? When you say that changing to a template makes it "work", can you explain? There''s something that I''m missing entirely here. I don''t know what problem you''re having. -- Think twice before you speak, and then you may be able to say something more insulting than if you spoke right out at once. - Evan Esar --------------------------------------------------------------------- Luke Kanies | http://reductivelabs.com | http://madstop.com
By the way, in trying to reproduce some of the problems you were
having, I found that virtual defined resources and definitions
wrapping virtual resources (which are syntactically equivalent to
exported resources) did not work as I expect.
I just committed some code that revamps it considerably and should
work better.
At this point, I would not be surprised if you could not get desired
behaviour with definitions wrapping exported resources.

When i override the @@file it does not override the ''content'' of it if the content is a simple string like "$utilisateurs". If i replace the string by template() the template used being the very same thing (ie <%= utilisateurs %> ) then the overriding works. so having content => "$utilisateurs" or content => template(bmah) does not provide the same result when you override the ressource (it works as espected when you just set the ressource, this is a problem in overriding it). The second is overriden correctly and the first is not. -- Cordialement, Ghislain _______________________________________________ Puppet-users mailing list Puppet-users@madstop.com https://mail.madstop.com/mailman/listinfo/puppet-users
