Subject Re: [VOTE] Accept NuttX into the Apache Incubator
Date Thu, 05 Dec 2019 02:28:05 GMT

+1 (no binding)

    Hi folks,
    The [DISCUSS] thread on NuttX has died down.
    Accordingly, I would like to call a VOTE to accept NuttX into the
    Apache Incubator.
    Please cast your vote:
      [ ] +1, bring NuttX into the Incubator
      [ ] +0, I don't care either way
      [ ] -1, do not bring NuttX into the Incubator, because...
    The vote will open at least for 72 hours and only votes from the
    Incubator PMC are binding, but votes from everyone are welcome.
    NuttX is a mature, real-time embedded operating system (RTOS).  It has wide
    usage in IoT projects, control systems, robotics, drones, and many other
    systems.  Unique properties of NuttX are its strict adherence to standards
    and its scalability. NuttX follows the Unix standards as defined
    by (POSIX, ANSI, and others).  This allows for a high degree
    of portability. Scalability is supported through a configuration system
    that allows NuttX to run on the smallest embedded platforms and through
    high end single board computers.
    NuttX was released under a BSD 3-Clause license on February 17, 2007.  From
    that time until now it has been managed by a single person, Gregory Nutt.
    The user base of NuttX has grown to probably thousands of projects and
    perhaps a hundred active developments at any time.  The code base has grown
    to around 1.5 million lines of code (according to
    NuttX has benefited from this single person management because this has
    resulted in a consistent architecture and controlled growth.  But now it is
    time to open this project to the participation of others because this
    consistent architecture assures solid future growth, and because the
    magnitude of effort required to support the RTOS exceeds the capability of
    a single person, but also because users of NuttX require a stable road map
    going forward that does not depend on a single person.
    For these reasons, I propose that NuttX enter the Apache Incubator as a
    first step in opening the project to wider participation.
    =Initial Goals=
    The initial goal will be to move the existing BSD code base to Apache and
    integrate with the Apache development process and infrastructure. A primary
    goal of incubation will be to grow and diversify the NuttX community. We
    will convert that code base to the Apache license during incubation.
    =Current Status=
    As previously mentioned, NuttX is a mature, stable product in wide use in
    embedded products.
    We value meritocracy and we understand that it is the basis for an open
    community that encourages multiple companies and individuals to contribute
    and be invested in the project’s future. We will encourage and monitor
    participation and make sure to extend privileges and responsibilities to
    all contributors.
    Being a mature project, NuttX already has an extensive user base with many
    people who understand the software, who have committed hundreds of changes,
    and are happy to participate in the project.  I believe that with a little
    guidance and formalization, a PMC and a large group of experienced
    committers can quickly be established.
    NuttX has a large, active community.  Communication is via a Google group
    at!forum/nuttx where there are 395
    members as of this writing.  Code is currently maintained
    at at  Other communications are
    through Bitbucket issues and also via Slack for focused, interactive
    Keeping up with the communications, requests for help, issues, and
    contributions is more than a full time job at this time.
    ==Core Developers==
    NuttX was initially developed by Gregory Nutt, released as an open source
    project on February 17, 2007, and is still under active development.  There
    are several dozen, active, frequent contributors involved with the project.
    The core OS can be considered finished at this point, but development
    continues in specialized areas of networking, IoT, cryptography, tools, and
    other more specialized functions.
    NuttX is an original development with some small percentage of ported
    code.  It stands alone depends on no other projects.
    =Known Risks=
    ==Orphaned Products==
    We are committed to the future development of NuttX and understand that
    graduation to a TLP, while preferable, is not the only positive outcome of
    Should the NuttX project be accepted by the Incubator, the prospective PPMC
    would be willing to agree to a target incubation period of 2 years or less,
    knowing that every Incubator project incurs a certain cost in terms of ASF
    infrastructure and volunteer time.
    ==Inexperience with Open Source==
    None of the initial committers are Apache members and we will need some
    help in learning the Apache Way.
    ==Salaried Developers==
    It is expected that NuttX development will occur primarily on volunteer
    time, after hours.  One initial committer will be paid by Xiaomi. All
    initial committers are all equally passionate about the project.
    =Relationships with Other Apache Products=
    There is no relationship between NuttX and any other Apache Products.
    There were discussions with the Mynewt project in the past concerning use
    of some Mynewt IoT components within NuttX.  There is some possibility that
    those conversations could continue once NuttX has Apache licensing as well.
    =Required Resources=
    ==Mailing lists==
    The podling may also create a user mailing list, if needed.
    ==Source Control and Issue Tracking==
    NuttX current uses the Bitbucket infrastructure for development.  It is
    likely that the NuttX podling would switch to GitHub and would use Apache’s
    gitbox integration to sync between GitHub and Apache infrastructure. The
    podling would use GitHub issues and pull requests for community engagement.
    Current Resources
    * Initial source:
    * Wiki Page:
    * Google Group:!forum/nuttx
    =Source and Intellectual Property Submission Plan=
    The NuttX  source code in Bitbucket is currently licensed under the BSD
    3-clause license and the most copyrights are assigned to the author,
    Gregory Nutt. If NuttX becomes an Incubator project at the ASF, the project
    will transfer the source code and trademark ownership to the Apache
    Software Foundation via a Software Grant Agreement.
    =External Dependencies=
    None.  A small number of files within NuttX follow slightly different, but
    compatible licenses including BSD 2- and 4-clause, MIT, ISC, and Public
    NuttX has negligible cryptographic capabilities at present.  This is,
    however, and are where there will be extensive future growth.
