Contributing to Ohai
We are glad you want to contribute to Ohai!
We utilize Github Issues for issue tracking and contributions. You can contribute in two ways:
- Reporting an issue or making a feature request here.
- Adding features or fixing bugs yourself and contributing your code to Ohai.
We have a 3 step process that utilizes Github Issues:
- Sign or be added to an existing Contributor License Agreement (CLA).
- Create a Github Pull Request.
- Do Code Review with the Chef Engineering Team or Chef Core Committers on the pull request.
Ohai is built to last. We strive to ensure high quality throughout the Ohai experience. In order to ensure this, we require a couple of things for all pull requests to Ohai:
- Tests: To ensure high quality code and protect against future regressions, we require all the
code in Ohai to have at least unit test coverage. See the spec/unit
directory for the existing tests and use
bundle exec rake specto run them.
- Green Travis Run: We use Travis CI in order to run our tests continuously on all the pull requests. We require the Travis runs to succeed on every pull request before being merged.
In addition to this it would be nice to include the description of the problem you are solving with your change. You can use the Issue Template in the description section of the pull request.
The code review process happens via Github pull requests. See this article if you're not familiar with Github Pull Requests.
Once you a pull request, the Chef Engineering Team or Chef Core Committers will review your code and respond to you with any feedback they might have. The process at this point is as follows:
- 2 thumbs-ups are required from the Chef Engineering Team or Chef Core Committers for all merges.
- When ready, your pull request will be tagged with label
Ready For Merge.
- Your patch will be merged into
masterincluding necessary documentation updates and you will be included in
CHANGELOG.md. Our goal is to have patches merged in 2 weeks after they are marked to be merged.
If you would like to learn about when your code will be available in a release of Ohai, read more about the Release Process.
Contributor License Agreement (CLA)
Licensing is very important to open source projects. It helps ensure the software continues to be available under the terms that the author desired.
Chef uses the Apache 2.0 license to strike a balance between open contribution and allowing you to use the software however you would like to.
The license tells you what rights you have that are provided by the copyright holder. It is important that the contributor fully understands what rights they are licensing and agrees to them. Sometimes the copyright holder isn't the contributor, such as when the contributor is doing work for a company.
To make a good faith effort to ensure these criteria are met, Chef requires an Individual CLA or a Corporate CLA for contributions. This agreement helps ensure you are aware of the terms of the license you are contributing your copyrighted works under, which helps to prevent the inclusion of works in the projects that the contributor does not hold the rights to share.
It only takes a few minutes to complete a CLA, and you retain the copyright to your contribution.
Chef Obvious Fix Policy
Small contributions such as fixing spelling errors, where the content is small enough to not be considered intellectual property, can be submitted by a contributor as a patch, without a CLA.
As a rule of thumb, changes are obvious fixes if they do not introduce any new functionality or creative thinking. As long as the change does not affect functionality, some likely examples include the following:
- Spelling / grammar fixes
- Typo correction, white space and formatting changes
- Comment clean up
- Bug fixes that change default return values or error codes stored in constants
- Adding logging messages or debugging output
- Changes to ‘metadata’ files like Gemfile, .gitignore, build scripts, etc.
- Moving source files from one directory or package to another
Whenever you invoke the “obvious fix” rule, please say so in your commit message:
------------------------------------------------------------------------ commit 370adb3f82d55d912b0cf9c1d1e99b132a8ed3b5 Author: danielsdeleo <email@example.com> Date: Wed Sep 18 11:44:40 2013 -0700 Fix typo in config file docs. Obvious fix. ------------------------------------------------------------------------
Ohai Issue Tracking is handled using Github Issues.
If you are familiar with Ohai and know the component that is causing you a problem or if you have a feature request on a specific component you can file an issue in the corresponding Github project. All of our Open Source Software can be found in our Github organization.
Otherwise you can file your issue in the Ohai project and we will make sure it gets filed against the appropriate project.
In order to decrease the back and forth in issues, and to help us get to the bottom of them quickly we use the below issue template. You can copy/paste this template into the issue you are opening and edit it accordingly.
### Version: [Version of the project installed] ### Environment: [Details about the environment such as the Operating System, cloud provider, etc...] ### Scenario: [What you are trying to achieve and you can't?] ### Steps to Reproduce: [If you are filing an issue what are the things we need to do in order to repro your problem?] ### Expected Result: [What are you expecting to happen as the consequence of above reproduction steps?] ### Actual Result: [What actually happens after the reproduction steps?]
Our primary shipping vehicle is operating system specific packages that includes all the requirements of Chef and Ohai. We call these Omnibus packages
We also release our software as gems to Rubygems but we strongly recommend using the Chef packages, since they are the only combination of native libraries and gems required by Ohai that we test throughly.
Our version numbering closely follows Semantic Versioning standard. Our standard version numbers look like X.Y.Z which mean:
- X is a major release, which may not be fully compatible with prior major releases
- Y is a minor release, which adds both new features and bug fixes
- Z is a patch release, which adds just bug fixes
We frequently make
beta releases with version numbers that look like
X.Y.Z.beta.1. These releases are still well tested but not as
throughly as Minor or Patch releases.
We do a
Minor release approximately every 3 months and
Patch releases on a when-needed
basis for regressions, significant bugs, and security issues.
Announcements of releases are available on Chef Blog at the time of release
Ohai is made possible by a strong community of developers and system administrators in the Chef community. If you have any questions or if you would like to get involved in the community you can check out:
