- name: Fail if migration version is not validated (first-time onboarding)
  ansible.builtin.fail:
    msg: >-
      This playbook now uses a migration validation system to help you stay aware of breaking changes.

      It appears that you haven't configured the `matrix_playbook_migration_validated_version` variable yet.

      Please review the changelog (https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/CHANGELOG.md)
      and then add the following to your vars.yml file:

      matrix_playbook_migration_validated_version: {{ matrix_playbook_migration_expected_version }}
  when: "matrix_playbook_migration_validated_version == ''"

- name: Fail if migration version is outdated
  ansible.builtin.fail:
    msg: |-
      Your validated migration version ({{ matrix_playbook_migration_validated_version }}) is behind the expected version ({{ matrix_playbook_migration_expected_version }}).

      The following breaking changes have been introduced since your last validation:

      {% for item in matrix_playbook_migration_breaking_changes | selectattr('version', '>', matrix_playbook_migration_validated_version) | sort(attribute='version') %}
      - {{ item.version }}: {{ item.summary }} ({{ item.changelog_url }})
      {% endfor %}

      After reviewing the above changes and adapting your setup, update your vars.yml:

      matrix_playbook_migration_validated_version: "{{ matrix_playbook_migration_expected_version }}"
  when: "matrix_playbook_migration_validated_version != '' and matrix_playbook_migration_validated_version < matrix_playbook_migration_expected_version"
