You are under no obligation whatsoever to provide any bug fixes, patches, or upgrades to the features, functionality or performance of the source code ("Enhancements") to anyone; however, if you choose to make your Enhancements available either publicly, or directly to the project, without imposing a separate written license agreement for such Enhancements, then you hereby grant the following license: a non-exclusive, royalty-free perpetual license to install, use, modify, prepare derivative works, incorporate into other computer software, distribute, and sublicense such enhancements or derivative works thereof, in binary and source code form.
When contributing to Singularity, it is important to properly communicate the gist of the contribution. If it is a simple code or editorial fix, simply explaining this within the GitHub Pull Request (PR) will suffice. But if this is a larger fix or Enhancement, it should be first discussed with the project leader or developers.
Please note we have a code of conduct, described below. Please follow it in all your interactions with the project members and users.
- Bug fix PRs should be sent to both the master and development branches. Feature enhancements should only be submitted against the development branch.
- Follow the existing code style precedent. This does not need to be strictly defined as there are many thousands of lines of examples. Note the lack of tabs anywhere in the project, parentheses and spacing, curly bracket locations, source code layout, variable scoping, etc. and follow the project's standards.
- Ensure any install or build dependencies are removed before doing a build to test your PR locally.
- For any new functionality, please write a test to be added to Continuous
Integration (Travis) to test it (tests can be found in the
tests/directory). - The project's default copyright and header have been included in any new source files.
- Make sure you have implemented a local
make testand all tests succeed before submitting the PR. - All (major) changes to Singularity must be documented on singularityware.github.io. If your PR changes a core functionality, please include clear description of the changes in your PR so that the docs can be updated, or better, submit a sister PR to update the docs directly.
- If necessary, update the README.md, and check the
*.helpscripts under libexec/cli that provide the command line helper output. If you make changes to the internal Python API, make sure to check those changes into the libexec/python/README.md as well. - Is the code human understandable? This can be accomplished via a clear code style as well as documentation and/or comments.
- The pull request will be reviewed by others, and the final merge must be done by the Singularity project lead, @gmkurtzer (or approved by him).
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
Examples of behavior that contributes to creating a positive environment include:
- Using welcoming and inclusive language
- Being respectful of differing viewpoints and experiences
- Gracefully accepting constructive criticism
- Focusing on what is best for the community
- Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
- The use of sexualized language or imagery and unwelcome sexual attention or advances
- Trolling, insulting/derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing others' private information, such as a physical or electronic address, without explicit permission
- Other conduct which could reasonably be considered inappropriate in a professional setting
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project leader ([email protected]). All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
Project maintainers, contributors and users who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions with their involvement in the project as determined by the project's leader(s).
