The first line should include + the issue number in the form "(#XXXX) Rest of message". + + - The body should provide a meaningful commit message, which: + + - uses the imperative, present tense: "change", not "changed" or + "changes". + + - includes motivation for the change, and contrasts its + implementation with the previous behavior. + + - Make sure that you have tests for the bug you are fixing, or + feature you are adding. + + - Make sure the test suites passes after your commit: + `bundle exec rspec spec/acceptance` More information on [testing](#Testing) below + + - When introducing a new feature, make sure it is properly + documented in the README.md + + * Submission: + + * Pre-requisites: + + - Make sure you have a [GitHub account](https://github.com/join) + + - [Create a ticket](https://tickets.puppetlabs.com/secure/CreateIssue!default.jspa), or [watch the ticket](https://tickets.puppetlabs.com/browse/) you are patching for. + + * Preferred method: + + - Fork the repository on GitHub. + + - Push your changes to a topic branch in your fork of the + repository. (the format ticket/1234-short_description_of_change is + usually preferred for this project). + + - Submit a pull request to the repository in the puppetlabs + organization. + +The long version +================ + + 1. Make separate commits for logically separate changes. + + Please break your commits down into logically consistent units + which include new or changed tests relevant to the rest of the + change. The goal of doing this is to make the diff easier to + read for whoever is reviewing your code. In general, the easier + your diff is to read, the more likely someone will be happy to + review it and get it into the code base. + + If you are going to refactor a piece of code, please do so as a + separate commit from your feature or bug fix changes. + + We also really appreciate changes that include tests to make + sure the bug is not re-introduced, and that the feature is not + accidentally broken. + + Describe the technical detail of the change(s). If your + description starts to get too long, that is a good sign that you + probably need to split up your commit into more finely grained + pieces. + + Commits which plainly describe the things which help + reviewers check the patch and future developers understand the + code are much more likely to be merged in with a minimum of + bike-shedding or requested changes. Ideally, the commit message + would include information, and be in a form suitable for + inclusion in the release notes for the version of Puppet that + includes them. + + Please also check that you are not introducing any trailing + whitespace or other "whitespace errors". You can do this by + running "git diff --check" on your changes before you commit. + + 2. Sending your patches + + To submit your changes via a GitHub pull request, we _highly_ + recommend that you have them on a topic branch, instead of + directly on "master". + It makes things much easier to keep track of, especially if + you decide to work on another thing before your first change + is merged in. + + GitHub has some pretty good + [general documentation](http://help.github.com/) on using + their site. They also have documentation on + [creating pull requests](http://help.github.com/send-pull-requests/). + + In general, after pushing your topic branch up to your + repository on GitHub, you can switch to the branch in the + GitHub UI and click "Pull Request" towards the top of the page + in order to open a pull request. + + + 3. Update the related GitHub issue. + + If there is a GitHub issue associated with the change you + submitted, then you should update the ticket to include the + location of your branch, along with any other commentary you + may wish to make. + +Testing +======= + +Getting Started +--------------- + +Our puppet modules provide [`Gemfile`](./Gemfile)s which can tell a ruby +package manager such as [bundler](http://bundler.io/) what Ruby packages, +or Gems, are required to build, develop, and test this software. + +Please make sure you have [bundler installed](http://bundler.io/#getting-started) +on your system, then use it to install all dependencies needed for this project, +by running + +```shell +% bundle install +Fetching gem metadata from https://rubygems.org/........ +Fetching gem metadata from https://rubygems.org/.. +Using rake (10.1.0) +Using builder (3.2.2) +-- 8><-- many more --><8 -- +Using rspec-system-puppet (2.2.0) +Using serverspec (0.6.3) +Using rspec-system-serverspec (1.0.0) +Using bundler (1.3.5) +Your bundle is complete! +Use `bundle show [gemname]` to see where a bundled gem is installed. +``` + +NOTE some systems may require you to run this command with sudo. + +If you already have those gems installed, make sure they are up-to-date: + +```shell +% bundle update +``` + +With all dependencies in place and up-to-date we can now run the tests: + +```shell +% rake spec +``` + +This will execute all the [rspec tests](http://rspec-puppet.com/) tests +under [spec/defines](./spec/defines), [spec/classes](./spec/classes), +and so on. rspec tests may have the same kind of dependencies as the +module they are testing. While the module defines in its [Modulefile](./Modulefile), +rspec tests define them in [.fixtures.yml](./fixtures.yml). + +Some puppet modules also come with [beaker](https://github.com/puppetlabs/beaker) +tests. These tests spin up a virtual machine under +[VirtualBox](https://www.virtualbox.org/)) with, controlling it with +[Vagrant](http://www.vagrantup.com/) to actually simulate scripted test +scenarios. In order to run these, you will need both of those tools +installed on your system. + +You can run them by issuing the following command + +```shell +% rake spec_clean +% rspec spec/acceptance +``` + +This will now download a pre-fabricated image configured in the [default node-set](./spec/acceptance/nodesets/default.yml), +install puppet, copy this module and install its dependencies per [spec/spec_helper_acceptance.rb](./spec/spec_helper_acceptance.rb) +and then run all the tests under [spec/acceptance](./spec/acceptance). + +Writing Tests +------------- + +XXX getting started writing tests. + +If you have commit access to the repository +=========================================== + +Even if you have commit access to the repository, you will still need to +go through the process above, and have someone else review and merge +in your changes. The rule is that all changes must be reviewed by a +developer on the project (that did not write the code) to ensure that +all changes go through a code review process. + +Having someone other than the author of the topic branch recorded as +performing the merge is the record that they performed the code +review. + + +Additional Resources +==================== + +* [Getting additional help](http://puppetlabs.com/community/get-help) + +* [Writing tests](http://projects.puppetlabs.com/projects/puppet/wiki/Development_Writing_Tests) + +* [Patchwork](https://patchwork.puppetlabs.com) + +* [General GitHub documentation](http://help.github.com/) + +* [GitHub pull request documentation](http://help.github.com/send-pull-requests/) + |
