contributor guidelines
^^^^^^^^^^^^^^^^^^^^^^
Filing Bugs
-----------
Bugs should be filed on Launchpad, not GitHub: "https://bugs.launchpad.net/openstack-ansible"
When submitting a bug, or working on a bug, please ensure the following criteria are met:
* The description clearly states or describes the original problem or root cause of the problem.
* Include historical information on how the problem was identified.
* Any relevant logs are included.
* The provided information should be totally self-contained. External access to web services/sites should not be needed.
* Steps to reproduce the problem if possible.
Submitting Code
---------------
Changes to the project should be submitted for review via the Gerrit tool, following
the workflow documented at: "http://docs.openstack.org/infra/manual/developers.html#development-workflow"
Pull requests submitted through GitHub will be ignored and closed without regard.
Extra
-----
Tags:
If it's a bug that needs fixing in a branch in addition to Master, add a '\<release\>-backport-potential' tag (eg ``juno-backport-potential``). There are predefined tags that will autocomplete.
Status:
Please leave this alone, it should be New till someone triages the issue.
Importance:
Should only be touched if it is a Blocker/Gating issue. If it is, please set to High, and only use Critical if you have found a bug that can take down whole infrastructures.
Style guide
-----------
When creating tasks and other roles for use in Ansible please create then using the YAML dictionary format.
Example YAML dictionary format:
.. code-block:: yaml
- name: The name of the tasks
module_name:
thing1: "some-stuff"
thing2: "some-other-stuff"
tags:
- some-tag
- some-other-tag
Example **NOT** in YAML dictionary format:
.. code-block:: yaml
- name: The name of the tasks
module_name: thing1="some-stuff" thing2="some-other-stuff"
tags:
- some-tag
- some-other-tag
Usage of the ">" and "|" operators should be limited to Ansible conditionals and command modules such as the ansible ``shell`` module.
Issues
------
When submitting an issue, or working on an issue please ensure the following criteria are met:
* The description clearly states or describes the original problem or root cause of the problem.
* Include historical information on how the problem was identified.
* Any relevant logs are included.
* If the issue is a bug that needs fixing in a branch other than Master, add the ‘backport potential’ tag TO THE ISSUE (not the PR).
* The provided information should be totally self-contained. External access to web services/sites should not be needed.
* If the issue is needed for a hotfix release, add the 'expedite' label.
* Steps to reproduce the problem if possible.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
