Hi,

I’m trying to notify handlers using vars in its name. If same role is called twice with diffferent vars - handlers start duplicating.

# role1/handlers/main.yml

- name: restart var1  
shell: echo restart var1

- name: restart var2  
shell: echo restart var2

# role1/tasks/main.yml

- shell: echo hi  
notify:
- restart {{ var }}

# playbook.yml

- hosts: localhost  
gather\_facts: no  
roles:
- role: role1  
var: var1
- role: role1  
var: var2

Output I get:

192.168.33.10 : ok=6 changed=6 unreachable=0 failed=0

I expect that each handler will be called only once. Having 3 role definitions will result in 9 notifications (3 per each handler)  
Ansible: latest 1.3 HEAD

Is that a bug or my configuration problem?

Well a handler could be parameterized, so … it depends.

We have talked about a way for the new role dependencies to require a role that could be included only once (by some intelligence built into the meta/ information in the role) that would allow you to require some\_other role that defined the handler in one place.
