Is there a way for a puppet agent run to "know" that the version of a package has changed ?

If the version update is done in the run, you can get a notify event from the package resource.

My use-case is when the update is done outside of Puppet.

The package in question is the mysql family. When the version of the software changes, you probably need to run "mysql_upgrade" to upgrade the database system tables.

The problem is that I need to know the version of the package from two different states.
I could do something kloooodjy like output the version to a text file and then read it back and compare it, but I was hoping for a more elegant solution.

You're looking for the meta-attribute “audit”.

package { 'my_sql_database':
  ensure => present,
  name   => 'mysqld',
  audit  => 'ensure',
}

Package['my_sql_database'] ~> Exec['mysql_upgrade']

exec { 'mysql_upgrade':
  command     => '/usr/bin/mysql_upgrade -y',
  refreshonly => true,
}

PS: OK, this doesn't let you know, which version puppet previously recorded and what version it is now.
