How Can I Contribute Bug and Feature Patches?

You can use the GitHub Pull Request model to submit a bug patch or feature patch.

• Fork it
• Create a branch (git checkout -b my_markup)
• Commit your changes (git commit -am “My changes”)
• Push to the branch (git push origin my_markup)
• Create a Pull Request to this repository from your new branch

It is understood that your patch addresses an open issue in GitHub. Update the issue with a full description of what you have done, describe your tests, and include a link to the Pull Request. When your patch is reviewed, it may be accepted “as-is” or you may be asked to make changes. Code commits (after review) will be implemented as named commits.

How Can I Contribute New Functional Components?

Before entering a new issue following the Feature Request process, first check if there is already an open issue addressing a similar feature. Describe your work plan and the resources you are planning to allocate in the issue. Then you should bring it up for discussion on the Community Forum. Other developers may have suggestions, and this ensures that the new feature is aligned with the roadmap and other features being developed. It is important to be sure that you’re not doing redundant work.

New features can be:

• Enhancements in the OpenNebula core distribution. These should be contributed by following the process to contribute feature patches.
• New interfaces and drivers that extend platform support. New tools, interfaces and drivers that broaden the platform technologies and services with which OpenNebula can interface are published on the Add-ons catalog. These may be incorporated into the main OpenNebula distribution after an incubation process. Visit our Add-on section for more information about how to contribute new Add-ons or contribute to an existing Add-on
