The DCO2 project accepts contributions via GitHub pull requests. This document outlines the process to help get your contribution accepted.
Feature requests, bug reports, and support requests all occur through GitHub issues and discussions. If you would like to file an issue, view existing issues, or comment on an issue please engage with issues at https://github.com/cncf/dco2/issues. You can create new discussions, view existing ones and comment on them at https://github.com/cncf/dco2/discussions.
All changes to the source code and documentation are made through GitHub pull requests. If you would like to make a change to the source, documentation, or other component in the repository please open a pull request with the change.
If you are unsure if the change will be welcome you may want to file an issue first. The issue can detail the change and you can get feedback from the maintainers prior to starting to make the change.
You can find the existing pull requests at https://github.com/cncf/dco2/pulls.
The DCO2 project uses a Developers Certificate of Origin (DCO) to sign-off that you have the right to contribute the code being contributed. The full text of the DCO reads:
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
1 Letterman Drive
Suite D4700
San Francisco, CA, 94129
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
Every commit needs to have signoff added to it with a message like:
Signed-off-by: Joe Smith <joe.smith@example.com>
Git makes doing this fairly straight forward. First, please use your real name (sorry, no pseudonyms or anonymous contributions).
If you set your user.name and user.email in your git configuration, you can sign your commit automatically with git commit -s or git commit --signoff.
Signed commits in the git log will look something like:
Author: Joe Smith <joe.smith@example.com>
Date: Thu Feb 2 11:41:15 2018 -0800
Update README
Signed-off-by: Joe Smith <joe.smith@example.com>
Notice how the Author and Signed-off-by lines match. If they do not match the PR will be rejected by the automated DCO check.
If more than one person contributed to a commit than there can be more than one Signed-off-by line where each line is a signoff from a different person who contributed to the commit.
