Fork a Respository

A 'fork' on GitHub is your own personal copy of a repository. GitHub's guide to forking a repository is available here. You will need a fork to contribute to Desired State Configuration Resources for VMware since only the maintainers have the ability to push to the official repositories.

Clone your Fork

You will want to clone your fork so that you can edit code locally on your machine. GitHub's guide to cloning is available here.

Create a Working Branch

Your fork is your personal territory. You may set it up however best suits your workflow, but we recommend that you set up a working branch separate from the default master branch. Creating a working branch separate from the default master branch will allow you to create other working branches off of master later while your original working branch is still open for code reviews. Limiting your current working branch to a single issue will also both streamline the code review and reduce the possibility of merge conflicts.

The Git guide to branching is available here.

Make Code Changes

If you are creating new DSC Resource for VMware, you need to get familiar with the following guidelines: Coding Guidelines Pay attention to any new code merged into the master branch of the official repository. If this occurs, you will need to pick-up these changes in your fork.

Submit a Pull Request

A pull request (PR) allows you to submit the changes you made in your fork to the official repository.

To open a pull request, go to the Pull Requests tab of either your fork or the official repository.

Click the New Pull Request button.

The base is the repository and branch the pull request will be merging into. The target is the repository and branch the pull request will be merging from. For Desired State Configuration Resources for VMware, always create a pull request with the base as the master branch of the official repository. The target should be your working branch in your fork.

Once you select the correct base and target, you can review the file and commits that will be included in the pull request by selecting the tabs below the Create Pull Requests Button.

If GitHub tells you that your branches cannot automatically be merged, you probably have merge conflicts. These should be fixed before you submit your pull request.

Once you are ready to submit your pull request, click the Create Pull Request button.

Pull Request Title

The title of your PR should describe the changes it includes in one line. Simply putting the issue number that the PR fixes is not acceptable. If your PR deals with one specific resource, please prefix the title with the resource name followed by a colon. If your PR fixes an issue please do still include "(Fixes #issue number)" in the title. For example, if a PR fixes issues number 11 and 16 which adds the Ensure parameter to the VMHostTpsSettings resource, the title should be something like: "VMHostTpsSettings: Added Ensure parameter (Fixes #11, #16)".

If you open a pull request with the wrong title, you can easily edit it by clicking the Edit button.

Pull Request Description

The description of your PR should include a detailed report of all the changes you made. If your PR fixes an issue please include the number in the description. Please tag anyone you would specifically like to see this PR with the @ symbol followed by their GitHub username (e.g. @sgerginov).

Once you are satisfied with the title, description and file changes included, submit the pull request.

Get your Code Reviewed

Only maintainers can review your code and only maintainers can merge your code. If you have specific maintainers you want to review your code, be sure to tag them in your pull request.

Reviewing Pull Requests

Pull requests should not be reviewed while tests are failing. If you are confused why tests are failing, tag a maintainer or ask the community for help.

Making Review Comments

Some things to pay attention to while reviewing:

  • Does the code logic make sense?
  • Does the code structure make sense?
  • Does this make the resource better?
  • Is the code easy to read?
  • Do all variables, parameters, and functions have descriptive names? (e.g. no $params, $args, $i, $a, etc.)
  • Does every function have a help comment?
  • Does the code follow the Coding Guidelines?
  • Has the author included test coverage for their changes?

Proposing DSC Resources

Each proposed new DSC Resource should be announced via an Issue. The proposed resources will be reviewed by the maintainers of the repository. The person who proposes the new resource can start developing it right after it is approved by the maintainers of the repository or leave it to other contributors who want to work on the new resource.

For more complex resources it may be neccessary to have more than one contributor working on it - this will be reviewed by the maintainers: how many people are needed for the development of the resource.

Everyone who wants to contribute to new resources can volunteer - For example if the person who submitted the issue needs assistance or does not have time to continue working on the resource.

If the assignee of the Issue has any questions, they can ask a maintainer or other members from the community.

When the assignee is ready with the new Resource, PR should be opened which will then be reviewed by the maintainers.
