Ansible when statements NOT WORKING when checking the ansible_os_family fact

[vma...@gigware.com]

Ok so I have this code(using version 2.0.1.0 of ansible):
<pre>

---

- hosts: localhost

  become: yes

  gather_facts: yes

  vars:

    version: "6.5.5"

  vars_files:

    - vars/{{ ansible_os_family }}.yml

  roles:

    - role: ubuntu_packages

      tags: ubuntu_packages

      when: ansible_os_family == "Debian"

    - role: redhat_packages

      tags: redhat_packages

      when: ansible_os_family == "RedHat"

    - role: windows_packages

      tags: windows_packages

      when: ansible_os_family == "Windows"

</pre>

But when I run it using ansible-playbook foo.yml, Im getting:
<pre>

PLAY ***************************************************************************

TASK [setup] *******************************************************************

ok: [localhost]

TASK [ubuntu_packages : include_vars] ******************************************

ok: [localhost] => (item=/root/scanner/ubuntu_packages/vars/Ubuntu_14.yml)

TASK [ubuntu_packages : Gather_ec2_facts] **************************************

ok: [localhost]

TASK [ubuntu_packages : debug] *************************************************

ok: [localhost] => {

    "file_url_full": "VARIABLE IS NOT DEFINED!"

}

TASK [redhat_packages : include_vars] ******************************************

fatal: [localhost]: FAILED! => {"failed": true, "msg": "No file was found when using with_first_found. Use the 'skip: true' option to allow this task to be skipped if no files are found"}

NO MORE HOSTS LEFT *************************************************************

        to retry, use: --limit @scanner.retry

PLAY RECAP *********************************************************************

localhost                  : ok=4    changed=0    unreachable=0    failed=1

</pre>

In other words the "when" statement is simply ignored when chosing the role and it executes the RedHat role right after the Ubuntu role although it shouldn't since ansible_os_family is Debian and if the when statement would work then there should be no error here. Seems like a serious bug in ansible.

Note: Tests are being done on ubuntu 14.04

I guess you just need to use "include" instead of "role:", then the
when-statement should work...

Conditionals are working as intended, it is not possible to make 'roles' conditional, any when: clause will be added to the tasks of the role, but do NOT prevent the import of the role itself.
