As an open-source project, we welcome and encourage the community to submit patches directly to project HAXM. In our collaborative open source environment, standards and methods for submitting changes help reduce the chaos that can result from an active development community.

This document explains how to submit patches to the project so your patch will be accepted quickly in the codebase.

Licensing is very important to open source projects. It helps ensure the software continues to be available under the terms that the author desired.

Project HAXM uses a BSD-3-Clause license, as found in the LICENSE in the project's GitHub repo.

A license tells you what rights you have as a developer, as provided by the copyright holder. It is important that the contributor fully understands the licensing rights and agrees to them. Sometimes the copyright holder isn't the contributor, such as when the contributor is doing work on behalf of a company.

To make a good faith effort to ensure licensing criteria are met, project HAXM requires the Developer Certificate of Origin (DCO) process to be followed.

The DCO is an attestation attached to every contribution made by every developer. In the commit message of the contribution (described more fully later in this document), the developer simply adds a Signed-off-by statement and thereby agrees to the DCO.

When a developer submits a patch, it is a commitment that the contributor has the right to submit the patch per the license. The DCO agreement is shown below and at https://developercertificate.org.

    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.

The DCO requires that a sign-off message, in the following format, appears on each commit in the pull request:

Signed-off-by: Haxmus Jones <[email protected]>

You are required to use your real name in the sign-off message.

The DCO text can either be manually added to your commit body, or you can add either -s or --signoff to your usual Git commit commands. If you forget to add the sign-off you can also amend a previous commit with the sign-off by running git commit --amend -s. If you've pushed your changes to GitHub already you'll need to force push your branch after this with git push -f.

Note:

The name and email address of the account you use to submit your PR must match the name and email address on the Signed-off-by line in your commit message.
