Hi,
I have noticed a very strance problem with my current puppet setup on
one of the nodes.
This is very peculiar problem indeed.
I have class php which looks like this:
# Class: php$major
#
# This module manages php$major installation for CentOS 5
#
class php (
$major = $php::params::major,
$package_ensure = $php::params::package_ensure,
$timezone = $::timezone,
) inherits php::params {
# packages from CentOS base
package { 'php':
ensure => $package_ensure,
name => "php${major}",
}
package { 'php-cli':
ensure => $package_ensure,
name => "php${major}-cli",
}
package { 'php-common':
ensure => $package_ensure,
name => "php${major}-common",
}
file { '/etc/php.d/timezone.ini':
ensure => file,
owner => root,
group => root,
mode => '0644',
content => template('php/timezone.ini.erb'),
require => Package['php-common'],
}
}
Now, I have many subclases for php modules, like this one:
# Class: php::mod::bcmath
class php::mod::bcmath (
$major = $php::major,
$package_ensure = $php::package_ensure,
) inherits php {
package { 'php-bcmath':
ensure => $package_ensure,
name => "php${major}-bcmath",
}
}
It's obvious that this class inherits class php.
Now, I have a following classes that include the php:
class system::templates::php {
include ::php
include ::php::mod::bcmath
}
But I also have a class system::php ,which only brings
/etc/php.d/system.ini :
class system::php {
file { '/etc/php.d/system.ini': }
}
Now, strange thing is, if system::php is present, puppet does automatic
include on every node that has some of the php::mod::* included...
But if I rm -f system/manifests/php.pp, not a single node reports an
error...
So, it's obvious that system::php is being pulled in catalog somehow, I
presume by the 'inherits php' code from php submodules. I have alot of
other code around, so I didn't (yet) try to code up the minimal possible
code that causes this behaviour... But sure as hell this is unintended
in my case...
I was pretty cautious in specifying top scope in numeros occasions when
including or requiring classes, but this time I thing that 'inherits'
bit me...
Has anyone had similar problems? Should I change my classes code in some
way to avoid this kind of issues in the future?
