 Contributing to VOLTHA
 ======================

 We'd love to accept your patches and contributions to the VOLTHA project. There are
 just a few small guidelines you need to follow.

 Contributor License Agreement
 -----------------------------

 Contributions to this project must be accompanied by a Contributor License
 Agreement. You (or your employer) retain the copyright to your contribution,
 this simply gives us permission to use and redistribute your contributions as
 part of the project. Head over to the `ONF CLA <https://cla.opennetworking.org/>`_ to see
 your current agreements on file or to sign a new one.

 You generally only need to submit a CLA once, so if you've already submitted one
 (even if it was for a different project), you probably don't need to do it
 again.

 Guides, Rules and Best Practices
 --------------------------------

 VOLTHA follows `Google's Engineering Practices <https://google.github.io/eng-practices/>`_,
 `Golang Formatting Guide <https://go.dev/doc/effective_go#formatting>`_. Use these documents as a guide when
 writing, submitting or reviewing code.
 VOLTHA uses gerrit to submit, review, tests and finally merge patches.

 Submitting Code
 +++++++++++++++

 Some additional points for developers:

  - Submit your changes early and often.  Code and design review input
    with corrections early in the process prevent huge changes later.
  - Please open a `jira ticket <https://jira.opencord.org/projects/VOL>`_ describing the issue/feature.
  - While checking in changes please preface the commit message with
    `[VOL-<jira_number]` e.g. `[VOL-4550]` to automatically link changesets,
    jenkins jobs, etc making them self-documenting for discussions.

 Steps to successful PRs
 +++++++++++++++++++++++

  1. Checkout the code base and prepare your patch.
  2. Workflow to modify VOLTHA code through gerrit is identical to `onos-classic`
     and is described in `Sample Gerrit Workflow page <https://wiki.onosproject.org/display/ONOS/Sample+Gerrit+Workflow>`_
  3. Before submitting your patch via `git review` please pre-screen your changes to ensure code quality.

  .. list-table:: Patch Pre-Screening
     :widths: 10, 40

     * - Command
       - Description
     * - `make lint <https://docs.voltha.org/master/howto/code/linting.html>`_
       - Syntax check source for problems
     * - make sca
       - Static Code Analysis
     * - make test
       - Invoke VOLTHA test suite(s)
     * - make help
       - Show available targets, bulk source cleanup needed for `make lint` to check everything by default.

  4. Submitting your patch will initiate a `jenkins job <https://jenkins.opencord.org>`_ to validate changes.
     Wait for job completion status before proceeding.

     - Job completion status will be sent to you asynchronously in email.
     - For direct monitoring `review comment history for your patch <https://gerrit.opencord.org/q/status:open+-is:wip>`_.
     - Search for `Jenkins Technical User <https://gerrit.opencord.org/c/voltha-docs/+/33952>`_ and click a job entry.
     - In the top grey navigation bar, following "Dashboard", click the test suite name to view the active job dashboard history `verify_voltha-docs_unit-test <https://jenkins.opencord.org/job/verify_voltha-docs_unit-test/>`_.

     If testing fails please fix your patch with step 3 an then repeat 2 and 3, as necessary.

     **Passing CI verification is mandatory.**

     If the CI check does not start or fails and you believe the issue is
     un-related to a changeset you can re-trigger by commenting on the
     patch with `recheck`.

     If failures persist `ask for assistance <https://wiki.opennetworking.org/display/COM/VOLTHA>`_ in slack or a mailing list.

  5. When comments are made to your patch please make the appropriate fixes and then
     amend your commit with `git commit --amend` and re-upload to gerrit with `git review`.

  6. Await review. Everyone can comment on code changes, but only Core contributors
     can give final review approval. **All changes must get at least one
     approval**. Join one of the `communication channels <https://wiki.opennetworking.org/display/COM/VOLTHA>`_
     to request a review or to bring additional attention to your patch.

 Versioning
 ++++++++++

 All of the VOLTHA components and the charts include a VERSION file that specifies
 the version of the service, library, protobuf, test suite included in the repository.
 The VERSION is in the format and follows the `SemVer principles <https://semver.org>`_
 VOLTHA also follows the guidelines on how to increment versions as described in the
 `SemVer specification <https://semver.org/#semantic-versioning-specification-semver>`_.

 Each increment of the VERSION file in a patch automatically triggers publishing of the repository
 artifact, e.g. docker images, with that tag.
 In VOLTHA we also use a `x.y.z-dev` format which identifies a non-released component (what is `master`).
 When a patch is merged with the `-dev` suffix in the VERSION file no artifact is published except for `master`
 docker images. The `-dev` suffix should be removed when a feature being worked on and the component
 is ready for release.

 We expect contributions to the VOLTHA codebase to follow these rules when submitting a patch
 and the same rules to be enforced by reviewers during the core review process.


 Core Contributors
 -----------------

 Anyone with a Gerrit account can open new issues, comment on existing issues, or
 contribute code by opening a review.

 A **“core contributor”** is someone who can manage, approve and
 merge patches, and create new branches in the main repository.

 Core contributors are responsible for maintaining the quality of contributions
 to the codebase. The goal of this program is to have a diverse group of
 individuals whose expertise in aggregate covers the entire project.

 The benefits of being a core contributor include:
  - Increased influence of the direction of the project
  - The ability to create branches in the main repository and after others approve it
    merge your own code
  - Community recognition and visibility for their contributions and expertise.

 Becoming a Core Contributor
 +++++++++++++++++++++++++++

 Core contributor candidates need to have a demonstrated proficiency with the
 VOLTHA codebase and a track record of code reviews.  Members of the Technical
 Steering Team (TST) and existing core contributors will regularly invite people
 to become new core contributors. Nominations can also be made (including
 self-nominations) to the VOLTHA TST (`voltha-tst@opennetworking.org`) at any time.

 A good nomination will include details about who the person is (including their email
 and Github and/or Gerrit username) and outline their experience with the VOLTHA codebase
 and project at large.
 Nominations are intended to start a conversation that results in a decision to
 make the person a core contributor – anyone whose nomination is not initially
 approved is encouraged to gain more experience with code submission and code
 review in order to gain further mastery over the codebase. Partial approval is
 also possible (e.g. a person may be granted the ability to handles patches only
 on a certain repository), and full approval may be granted after the contributor
 has gained more experience.

 New core contributors will be assigned a mentor that is either a TST member or
 existing core contributor. The mentor will serve as the primary point of contact
 to help onboard the new core contributors and answer any questions they have
 with their new responsibilities. The mentor is not the only point of contact,
 and core contributors should feel free to reach out to others if and when they
 have questions or concerns.

 Guidelines for Core Contributors
 ++++++++++++++++++++++++++++++++

 Contributions in VOLTHA can should be merged after two different +1 arrive on a
 given patch-set that is verified by CI as well.
 For your own contributions, you now have the ability to approve and merge your
 own code, pending that you received two other positive reviews.
 For larger or potentially controversial reviews, please give the
 community an opportunity (at least a few business days) to review your
 contribution. Please always ask for comments on the #voltha-dev Slack channel.
 **With great power comes great responsibility; please don't abuse
 this privilege.**

 All Core Contributors have +2 and merge capabilities on all the repositories related
 to the VOLTHA project, but we expect that they are responsible and exercise their
 privilege **only** on patches and repositories they have expertise in and are comfortable reviewing and merging.

 To help patchset verification the VOLTHA test infrastructure offers Per-Patchset Verification Jobs
 triggered by specific keyword used in the patch. More information can be found in the
 `testing automation page <https://docs.voltha.org/master/testing/voltha_test_automation.html#per-patchset-verification-jobs>`_
 We suggest Core contributors to use these triggers when they would like more checks on a patch they are uncertain about
 or that might have differences when applied to hardware pods.

 VOLTHA follows `Google’s best practices for code review <https://google.github.io/eng-practices/review/reviewer/>`_.
 You should apply these guidelines strictly and with confidence when reviewing
 submissions.

 If you are unsure about something in an issue or a review, leave a comment
 that outlines your concerns. If a resolution is difficult to reach in the
 comments section, the TST meetings are a good place to raise your concerns and
 have a discussion.
