Want to contribute? Great! You can do so through the standard GitHub pull request model. For large contributions we do encourage you to file a ticket in the GitHub issues tracking system prior to any code development to coordinate with the pcg_gazebo development team early in the process. Coordinating up front helps to avoid frustration later on.
Your contribution must be licensed under the Apache-2.0 license, the license used by this project.
Include a copyright notice and license in each new file to be contributed, consistent with the style used by this project. If your contribution contains code under the copyright of a third party, document its origin, license, and copyright holders.
This project tracks patch provenance and licensing using the Developer Certificate of Origin 1.1 (DCO) from developercertificate.org and Signed-off-by tags initially developed by the Linux kernel project.

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.
With the sign-off in a commit message you certify that you authored the patch or otherwise have the right to submit it under an open source license. The procedure is simple: To certify above Developer's Certificate of Origin 1.1 for your contribution just append a line
Signed-off-by: Random J Developer <[email protected]>
to every commit message using your real name or your pseudonym and a valid email address.
If you have set your user.name
and user.email
git configs you can
automatically sign the commit by running the git-commit command with the -s
option. There may be multiple sign-offs if more than one developer was
involved in authoring the contribution.
Another option to automatically add the Signed-off-by:
is to once use the
command
git config core.hooksPath .githooks
in your pcg_gazebo working directory. This will then add the Signed-off-by:
line
automatically.
For a more detailed description of this procedure, please see SubmittingPatches which was extracted from the Linux kernel project, and which is stored in an external repository.
Often employers or academic institution have ownership over code that is written in certain circumstances, so please do due diligence to ensure that you have the right to submit the code.
If you are a developer who is authorized to contribute to pcg_gazebo on behalf of your employer, then please use your corporate email address in the Signed-off-by tag. Otherwise please use a personal email address.
Each contributor is responsible for identifying themselves in the NOTICE file, the project's list of copyright holders and authors. Please add the respective information corresponding to the Signed-off-by tag as part of your first pull request.
If you are a developer who is authorized to contribute to pcg_gazebo on behalf of your employer, then add your company / organization to the list of copyright holders in the NOTICE file. As author of a corporate contribution you can also add your name and corporate email address as in the Signed-off-by tag.
If your contribution is covered by this project's DCO's clause "(c) The contribution was provided directly to me by some other person who certified (a) or (b) and I have not modified it", please add the appropriate copyright holder(s) to the NOTICE file as part of your contribution.
