[chef] notifying one resource from a provider

[Jesse Campbell < >]

For one of my projects, I need to be able to tell the deploy resource how to restart a service.

Currently, I do it like this:

  unless new_resource.restart_command
    new_resource.restart_command do
      run_context.resource_collection.find(:service => "tomcat6").run_action(:restart)
    end
  end

the trouble with this approach is that tomcat6 gets restarted immediately when deploy triggers a restart. Instead, I want deploy to "notify" tomcat6 to restart at the end of the chef run.

what function can be called to add something to the notification stack?

I'm thinking something like this, but no idea if it would work?

  unless new_resource.restart_command
    new_resource.restart_command do
      run_context.notifies_delayed(Chef::Resource::Notification.new(:service => "tomcat6", :restart, self))
    end
  end

Thanks!
