Get Ansible ongoing notify list

I'm looking for a way to get the list (possibly an ansible system variable) that would contain current handler notifications triggered by a playbook.

In other words, at some point in a role, I would like to add a "when" condition to a task that would test if a "restart notification" has not been sent yet -> do this task when restart is not in the notification list

Any idea ?

Thanks a lot!

I finally came to a solution, quite acceptable, using facts.

I use a handler to set a fact and another one to perform the restart. I associate both of them with the listen parameter to the same notification.

Besides, a reload handler performs the reload only when that fact is not defined or set to false.

- name: Register restart Logstash
  set_fact:
    restart_notified: true
  listen: "Restart Logstash"

- name: Restart Logstash service
  systemd:
    name: logstash
    daemon_reload: true
    state: restarted
  listen: "Restart Logstash"

- name: Reload Logstash
  systemd:
    name: logstash
    daemon_reload: true
    state: reloaded
  when: restart_notified is not defined or not restart_notified

I then use where needed, either Restart Logstash or Reload Logstash, and only one is performed, restart or reload, but never both.
