Contributing to Ansible
=======================
2012-09-18 04:55:06 +02:00
It is required that you read the following information to learn how to contribute to this project.
Branch Info
===========
2012-09-18 04:55:06 +02:00
Here's how to understand the branches.
* The devel branch corresponds to the latest ongoing release
* Various release-X.Y branches exist for previous releases
* All feature work happens on the development branch.
* Major bug fixes will be made to the last release branch only
* See CHANGELOG.md for release notes to track each release.
Patch Instructions
==================
Contributions to the core and modules are greatly welcome.
* Required Process:
* Submit github pull requests to the "ansible/devel" branch for features
* Fixes for bugs may also be submitted to "ansible/release-X.Y" for the last release
* Make sure "make tests" passes before submitting any requests.
* Bonus points:
* Joining the mailing list
* Fixing bugs instead of sending bug reports.
* Using squash merges

* Updating the "rst/*" files in the "docsite/" directory and "docs/" manpage content
* Adding more unit tests
* Avoid:
* Sending patches to the mailing list directly.
* Sending feature pull requests to the 'release' branch instead of the devel branch
* Sending pull requests to mpdehaan's personal ansible fork.
2012-09-18 04:55:06 +02:00
* Sending pull requests about more than one feature in the same pull request.
* Whitespace restructuring
* Large scale refactoring without a discussion on the list
Coding Standards
================
We're not too strict on style considerations, but we require:
* python 2.6 compliant code, unless in ansible modules, then python *2.4* compliant code (no 'with', etc)
* 4-space indents, no tabs except in Makefiles
* under_scores for method names and variables, not camelCase
* GPLv3 license headers on all files, with copyright on new files with your name on it
* no single-line if statements, deeply nested list comprehensions, or clever use of metaclasses -- keep it simple
* comments where appropriate
Testing Requirements
====================
Automation tests are run by "make tests" and contain a mixture of integration and "unit" level tests. To run the tests you need the following:
* nose must be installed - https://nose.readthedocs.org/en/latest/
* ansible tests require paramiko, PyYAML python modules, and python 2.6+.
* Some tests require additional components (facter, ohai) and will be skipped if not available.
* Your user environment should allow "ssh 127.0.0.1"
without a password - so a key held in ssh-agent and an authorized_keys entry.

If your module does not require any additional dependencies beyond ansible-core, it is a good idea to write some
tests for the module.
