First: We like to encourage you to contribute to the repository. If you're unsure or afraid of anything, just ask or submit the issue or pull request anyways. You won't be yelled at for giving your best effort. The worst that can happen is that you'll be politely asked to change something. We appreciate any sort of contributions, and don't want a wall of rules to get in the way of that.
However, for those individuals who want a bit more guidance on the best way to contribute to the project, read on. This document will cover what we're looking for. By addressing all the points we're looking for, it raises the chances we can quickly merge or address your contributions.
Before opening a new issue or pull request, we do appreciate if you take some time to search for possible duplicates, or similar discussions on HashiCorp Discuss. On GitHub, you can scope searches by labels to narrow things down.
To ensure that the Vagrant community remains an open and safe space for everyone we also follow the HashiCorp community guidelines. When contributing to Vagrant, please respect these guidelines.
Tip: We have provided a GitHub issue template. By respecting the proposed format and filling all the relevant sections, you'll strongly help the Vagrant collaborators to handle your request the best possible way.
- The issue is reported.
- The issue is verified and categorized by Vagrant collaborator(s). Categorization is done via GitHub tags for different dimensions (like issue type, affected components, pending actions, etc.)
- Unless it is critical, the issue is left for a period of time, giving outside contributors a chance to address the issue. Later, the issue may be assigned to a Vagrant collaborator and planned for a specific release milestone
- The issue is addressed in a pull request or commit. The issue will be referenced in the commit message so that the code that fixes it is clearly linked.
- The issue is closed. Sometimes, valid issues will be closed to keep the issue tracker clean. The issue is still indexed and available for future viewers, or can be re-opened if necessary.
- The issue is locked. After about 30 days the issue will be locked. This is done to keep issue activity in open issues and encourge users to open a new issue if an old issue is being encountered again.
Thank you for contributing! Here you'll find information on what to include in your Pull Request (“PR” for short) to ensure it is reviewed quickly, and possibly accepted.
Before starting work on a new feature or anything besides a minor bug fix, it is highly recommended to first initiate a discussion with the Vagrant community (either via a GitHub issue or HashiCorp Discuss). This will save you from wasting days implementing a feature that could be rejected in the end.
No pull request template is provided on GitHub. The expected changes are often already described and validated in an existing issue, that obviously should be referenced. The Pull Request thread should be mainly used for the code review.
Tip: Make it small! A focused PR gives you the best chance of having it accepted. Then, repeat if you have more to propose!
The Vagrant port to Go is currently in an alpha state and under heavy development. Please refer to this issue before starting or submitting pull requests related to Vagrant Go.
A Vagrantfile is provided that should take care setting up a VM for running the rspec tests. If you only need to run those tests and don't also want to run a development version of Vagrant from a host machine then it's recommended to use that.
There are a few prerequisites for setting up a development environment with Vagrant. Ensure you have the following installed on your machine:
- git
- bsdtar
- curl
It's nice to have a way to control what version of ruby is installed, so you may want to install rvm, chruby or rbenv. For Windows ruby installer is recommended.
Clone Vagrant's repository from GitHub into the directory where you keep code on your machine:
$ git clone --recurse-submodules https://github.com/hashicorp/vagrant.git
Next, move into the newly created ./vagrant directory.
$ cd ./vagrant
All commands will be run from this path. Now, run the bundle command to install the Ruby dependencies:
$ bundle install
You can now run Vagrant by running bundle exec vagrant from inside that directory.
Add the generated binstubs to your PATH
$ export PATH=/path/to/my/vagrant/binstubs
Install go using the method of your choice.
Build the Vagrant go binary using make
$ make
This will generate a ./vagrant binary in your project root.
Once you're confident that your upcoming changes will be accepted:
- In your forked repository, create a topic branch for your upcoming patch.
- Usually this is based on the main branch.
- Checkout a new branch based on main;
git checkout -b my-contrib mainPlease avoid working directly on themainbranch.
- Make focused commits of logical units and describe them properly.
- Avoid re-formatting of the existing code.
- Check for unnecessary whitespace with
git diff --checkbefore committing. - Tests are required in each pull request. There are some exceptions like docs changes and dependency constraint updates.
- Assure nothing is broken by running manual tests, and all the automated tests.
Vagrant uses rspec to run tests. Once your Vagrant bundle is installed from Git repository, you can run the test suite with:
bundle exec rake
This will run the unit test suite, which should come back all green!
If you are developing Vagrant on a machine that already has a Vagrant package installation present, both will attempt to use the same folder for their configuration (location of this folder depends on system). This can cause errors when Vagrant attempts to load plugins. In this case, override the VAGRANT_HOME environment variable for your development version of Vagrant before running any commands to be some new folder within the project or elsewhere on your machine. For example, in Bash:
export VAGRANT_HOME=~/.vagrant-dev
You can now run Vagrant commands against the development version:
bundle exec vagrant
Vagrant also comes with an acceptance test suite that does black-box tests of various Vagrant components. Note that these tests are extremely slow because actual VMs are spun up and down. The full test suite can take hours. Instead, try to run focused component tests.
To run the acceptance test suite, first copy vagrant-spec.config.example.rb
to vagrant-spec.config.rb and modify it to valid values. The places you
should fill in are clearly marked.
Next, see the components that can be tested:
$ rake acceptance:components
cli
provider/virtualbox/basic
...
Then, run one of those components:
$ rake acceptance:run COMPONENTS="cli"
...
- Push your changes to a topic branch in your fork of the repository.
- Open a PR to the original repository and choose the right original branch you want to patch (main for most cases).
- If not done in commit messages (which you really should do) please reference and update your issue with the code changes.
- Even if you have write access to the repository, do not directly push or merge your own pull requests. Let another team member review your PR and approve.
- You are welcome to submit your PR for commentary or review before it is fully completed. Please prefix the title of your PR with "[WIP]" to indicate this. It's also a good idea to include specific questions or items you'd like feedback on.
- Sign the HashiCorp CLA. If you haven't signed the CLA yet, a bot will ask you to do so. You only need to sign the CLA once. If you've already signed the CLA, the CLA status will be green automatically.
- The PR is categorized by Vagrant collaborator(s), applying GitHub tags similarly to issues triage.
- Once you believe your PR is ready to be merged, you can remove any "[WIP]" prefix from the title and a Vagrant collaborator will review.
- One of the Vagrant collaborators will look over your contribution and either provide comments letting you know if there is anything left to do. We do our best to provide feedback in a timely manner, but it may take some time for us to respond.
- Once all outstanding comments have been addressed, your contribution will be merged! Merged PRs will be included in the next Vagrant release. The Vagrant contributors will take care of updating the CHANGELOG as they merge.
- We might decide that a PR should be closed. We'll make sure to provide clear reasoning when this happens.
We require all contributors to sign the HashiCorp CLA.
In simple terms, the CLA affirms that the work you're contributing is original, that you grant HashiCorp permission to use that work (including license to any patents necessary), and that HashiCorp may relicense your work for our commercial products if necessary. Note that this description is a summary and the specific legal terms should be read directly in the CLA.
The CLA does not change the terms of the standard open source license used by our software such as MPL2 or MIT. You are still free to use our projects within your own projects or businesses, republish modified source, and more. Please reference the appropriate license of this project to learn more.
To sign the CLA, open a pull request as usual. If you haven't signed the CLA yet, a bot will respond with a link asking you to sign the CLA. We cannot merge any pull request until the CLA is signed. You only need to sign the CLA once. If you've signed the CLA before, the bot will not respond to your PR and your PR will be allowed to merge.
