Puppet users - Mar 2007 - some questions regarding inhert, unless/onlyif and notify on recursive objects

hello, 

i''m just playing around with the really great puppet to learn the
syntax
and see what it can do. i''m using puppet 0.22.1 on debian etch.

i created a aide class to distribute a modified aide.conf.d directory
and if not already done initialize the database (yes this should
probably be better organized and databas initialization should be
performed as the last step):

class aide {

        package { "aide":
                ensure => installed,
        }

        exec { "update-aide.conf":
                cwd => "/tmp",
                path => "/bin:/usr/bin:/sbin:/usr/sbin",
                command => "/usr/sbin/update-aide.conf",
        }

        exec { "aide.wrapper --init":
                cwd => "/tmp",
                path => "/bin:/usr/bin:/sbin:/usr/sbin",
                command => "if test ! -f /var/lib/aide/aide.db.new ;
then /usr/bin/aide.wrapper --init; fi",
                creates => "/var/lib/aide/aide.db.new",
                onlyif => "test ! -f /var/lib/aide/aide.db.new",
                subscribe => Exec["update-aide.conf"],
                notify =>
Exec["cp /var/lib/aide/aide.db.new /var/lib/aide/aide.db"],
        }

        exec { "cp /var/lib/aide/aide.db.new /var/lib/aide/aide.db":
                cwd => "/tmp",
                path => "/bin:/usr/bin:/sbin:/usr/sbin",
                command => "if test ! -f /var/lib/aide/aide.db ;
then /bin/cp /var/lib/aide/aide.db.new /var/lib/aide/aide.db; fi",
                onlyif => "test ! -f /var/lib/aide/aide.db",
        }

        file { "/etc/aide/aide.conf.d":
                source =>
"puppet://$puppetmaster/files/global/aide/aide.conf.d",
                recurse => "true",
                backup => false,
                ignore => ".svn",
                notify => Exec["update-aide.conf"],
        }
}

first problem:

"update-aide.conf" always gets called. even if no file has changed in
"/etc/aide/aide.conf.d" puppetd detects a change and notifies
update-aide.conf exec:

debug: //base_node/aide/Exec[update-aide.conf]: Changing returns
debug: //base_node/aide/Exec[update-aide.conf]: 1 change(s)
debug: //base_node/aide/Exec[update-aide.conf]: Executing
''/usr/sbin/update-aide.conf''

is it possible to enhance the debug level to actually see what that
change is supposed to be ? there''s no notice line about a change in the
debug log.

second problem:

onlyif/unless don''t work on notify/subscribe.
just realized this is fixed in 0.22.2+

third problem:

i''m using something like:

node ''base_node'':{

}

node ''node1.my.domain'' inherits base_node {

}

which works fine. it does not work if i also quote base_node:

node ''node1.my.domain'' inherits ''base_node''
{

}
Syntax error at ''base_node''
at /etc/puppet/manifests/nodes/node1.my.domain.pp

is this a bug in the parser or intended ?    

besides these small problems great work :-).

You should add ''refreshonly => true'' to the specification
of this
script.

The logging for ''exec'' isn''t as good because
it''s not really a
resource.  The work is done by the ''returns'' property, which
isn''t
really a property of course, which is the logging is weird.

The problem is that you need to enable refreshonly.

It''s a bug in the parser.  I''d appreciate it if you''d
file it as such.
