Contributing to FLUFFI

Contributions to FLUFFI are always welcome. This document explains the general requirements for contributions and the recommended preparation steps. It also sketches the typical integration process of patches.

1) Contribution Checklist

  • use git to manage your changes [recommended]

  • add the required copyright header to each new file introduced, see licensing information [required]

  • structure patches logically, in small steps [required]

    • one separable functionality/fix/refactoring = one patch
    • do not mix those three into a single patch (e.g., first refactor, then add a new functionality that builds onto the refactoring)
    • after each patch, the tree still has to build and work. Do not add even temporary breakages inside a patch series (helps when tracking down bugs)
    • use git rebase -i to restructure a patch series

  • base patches on top of latest master or - if there are dependencies - on next (note: next is an integration branch that may change non-linearly)

  • 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 fixes: to all bug-fix commits [recommended]

    • the fixes: tag format shall be: Fixes: 12-byte-hash ("subject of bug-introducting commit")
    • if you are unsure of the bug-introducing commit do not add a fixes: tag - no fixes: tag is better than a wrong fixes: tag.

  • post follow-up version(s) if feedback requires this

  • send reminder if nothing happens after about a week

2) Developer's Certificate of Origin 1.1

When signing-off a patch for this project like this

Signed-off-by: Random J Developer <random@developer.example.org>

using your real name (no pseudonyms or anonymous contributions), you declare the following:

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.
