The jinja2 query() function (or lookup with wantslist=True, which is
the same thing) should always return a list.
However, if you combine a query with errors='ignore' and take the
error path, the current code returns a None value. This is important
in a case such as
- name: Conditional include file
import_tasks: '{{ item }}'
vars:
params:
files:
- path/file1.yaml
- path/file2.yaml
loop: "{{ q('first_found', params, errors='ignore') }}"
If neither file1.yaml or file2.yaml exist, this should do nothing by
returning an empty list to the loop. Currently if you run the above
task you'll get a rather unhelpful:
Invalid data passed to 'loop', it requires a list, got this instead: .
This change ensures that when a query ignores an error, it returns a
empty list. The errors='ignore' case is tested in several variants
with first_found. The extant (but deprecated) "skip: True" for
first_found doesn't seem to be explicitly tested; a test is added here
to avoid regressions before removal in 2.12.
This fixes a regression you'll hit if you follow the suggestion in the
deprecation message included with

It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy. More information on `the Ansible website <https://ansible.com/>`_. Design Principles ================= * Have a dead simple setup process and a minimal learning curve. * Manage machines very quickly and in parallel. * Avoid custom-agents and additional open ports, be agentless by leveraging the existing SSH daemon. * Describe infrastructure in a language that is both machine and human friendly. * Focus on security and easy auditability/review/rewriting of content. * Manage new remote machines instantly, without bootstrapping any software. * Allow module development in any dynamic language, not just Python. * Be usable as non-root. * Be the easiest IT automation system to use, ever. Use Ansible =========== You can install a released version of Ansible via ``pip``, a package manager, or our `release repository <https://releases.ansible.com/ansible/>`_. See our `installation guide <https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html>`_ for details on installing Ansible on a variety of platforms. Red Hat offers supported builds of `Ansible Engine <https://www.ansible.com/ansible-engine>`_. Power users and developers can run the ``devel`` branch, which has the latest features and fixes, directly. Although it is reasonably stable, you are more likely to encounter breaking changes when running the ``devel`` branch. We recommend getting involved in the Ansible community if you want to run the ``devel`` branch. Get Involved ============ * Read `Community Information <https://docs.ansible.com/ansible/latest/community>`_ for all kinds of ways to contribute to and interact with the project, including mailing list information and how to submit bug reports and code to Ansible. * Join a `Working Group <https://github.com/ansible/community/wiki>`_, an organized community devoted to a specific technology domain or platform. * Submit a proposed code update through a pull request to the ``devel`` branch. * Talk to us before making larger changes to avoid duplicate efforts. This not only helps everyone know what is going on, it also helps save time and effort if we decide some changes are needed. * For a list of email lists, IRC channels and Working Groups, see the `Communication page <https://docs.ansible.com/ansible/latest/community/communication.html>`_ Branch Info =========== * The ``devel`` branch corresponds to the release actively under development. * The ``stable-2.X`` branches correspond to stable releases. * Create a branch based on ``devel`` and set up a `dev environment <https://docs.ansible.com/ansible/latest/dev_guide/developing_modules_general.html#common-environment-setup>`_ if you want to open a PR. * See the `Ansible release and maintenance <https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html>`_ page for information about active branches. Roadmap ======= Based on team and community feedback, an initial roadmap will be published for a major or minor version (ex: 2.7, 2.8). The `Ansible Roadmap page <https://docs.ansible.com/ansible/devel/roadmap/>`_ details what is planned and how to influence the roadmap. Authors ======= Ansible was created by `Michael DeHaan <https://github.com/mpdehaan>`_ and has contributions from over 4000 users (and growing).
