Contributing to SWUpdate

Contributions are welcome ! Please follow the following guideline for contributions.

Contribution Checklist

These are mostly general recommendations and are common practice in a lot of FOSS projects.

  • use git to manage your changes [recomended]

  • follow as much as possible kernel codestyle [recomended] Nevertheless, some rules are not so strict as in kernel. The maximum line length can be extended over 80 chars if this increase code readability.

  • add the required copyright header to each new file introduced [required]

  • add signed-off to all patches [required]

    • to certify the “Developer’s Certificate of Origin”, see below

    • check with your employer when not working on your own!

  • add version number for your patches if follow-up versions are requested [recomended]

    • Add a “Change from Vx” description under the commit message to take track of the history of the patch.

    • It is suggested to use excellent “patman” tool to manage patches series. This is part of U-Boot’s project (tools/patman), but it can be used in other projects, too.

  • check that your patches do not break build [required]

    • There is a set of configuration files in the configs/ directory. Please run a build for all files in the directory to ensure that SWUpdate is still buildable from configurations different as yours.

  • post patches to mailing list [required]

    • use git format-patch to generate your patches.

    • use git send-email if possible. This avoid corruptions due to the mailers

    • add a prefix [meta-swupdate] if patches are intended to the Yocto’s meta layer.

    • send patches inline, do not append them

    • no HTML emails!

  • do not use github Pull Request. github facilities are not used for this project. The review is done in a single place : the Mailing List. PR from github are ignored.

Patches are tracked by patchwork (see http://jk.ozlabs.org/projects/patchwork/). You can see the status of your patches at http://patchwork.ozlabs.org/project/swupdate/list.
