Identifying an area to contribute
|
||
|
|
---------------------------------
|
||
|
|
There are several ways to identify an area where you can contribute to Corda:
|
||
|
|
|
||
|
|
* Browse issues labelled as ``HelpWanted`` on the
|
||
|
|
`Corda JIRA board <https://r3-cev.atlassian.net/issues/?jql=labels%20%3D%20HelpWanted>`_
|
||
|
|
|
||
|
|
* Any issue with a ``HelpWanted`` label is considered ideal for open-source contributions
|
||
|
|
* If there is a feature you would like to add and there isn't a corresponding issue labelled as ``HelpWanted``, that
|
||
|
|
doesn't mean your contribution isn't welcome. Please reach out on the Corda Slack channel (see below) to clarify
|
||
|
|
|
||
|
|
* Check the `Corda GitHub issues <https://github.com/corda/corda/issues>`_
|
||
|
|
|
||
|
|
* It's always worth checking in the Corda Slack channel (see below) whether a given issue is a good target for your
|
||
|
|
contribution. Someone else may already be working on it, or it may be blocked by an on-going piece of work
|
||
|
|
|
||
|
|
* Ask in the `Corda Slack channel <http://slack.corda.net/>`_
|
||
|
|
|
||
|
|
Making the required changes
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
1. Create a fork of the master branch of the `Corda repo <https://github.com/corda/corda>`_
|
||
|
|
2. Clone the fork to your local machine
|
||
|
|
3. Make the changes, in accordance with the :doc:`code style guide </codestyle>`
|
||
|
|
|
||
|
|
Testing the changes
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Running the tests
|
||
|
|
^^^^^^^^^^^^^^^^^
|
||
|
|
Your changes must pass the tests described :doc:`here </testing>`.
|
||
|
|
|
||
|
|
Building against the master branch
|
||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
|
You may also want to test your changes against a CorDapp defined outside of the Corda repo. To do so, please follow the
|
||
|
|
instructions :doc:`here </building-against-master>`.
|
||
|
|
|
||
|
|
Merging the changes back into Corda
|
||
|
|
-----------------------------------
|
||
|
|
|
||
|
|
1. Create a pull request from your fork to the master branch of the Corda repo
|
||
|
|
2. Complete the pull-request checklist in the comments box:
|
||
|
|
|
||
|
|
* State that you have run the tests
|
||
|
|
* State that you have included JavaDocs for any new public APIs
|
||
|
|
* State that you have included the change in the :doc:`changelog </changelog>` and
|
||
|
|
:doc:`release notes </release-notes>` where applicable
|
||
|
|
* State that you are in agreement with the terms of
|
||
|
|
`CONTRIBUTING.md <https://github.com/corda/corda/blob/master/CONTRIBUTING.md>`_
|
||
|
|
|
||
|
|
3. Request a review from a member of the Corda platform team via the `Corda Slack channel <http://slack.corda.net/>`_
|
||
|
|
4. Wait for your PR to pass all four types of continuous integration tests (integration, API stability, build and unit)
|
||
|
|
|
||
|
|
* Currently, external contributors cannot see the output of these tests. If your PR fails a test that passed
|
||
|
|
locally, ask the reviewer for further details
|
||
|
|
|
||
|
|
5. Once a reviewer has approved the PR and the tests have passed, squash-and-merge the PR as a single commit
