Contributing to Apache Commons Math
|
|
======================
|
|
|
|
You have found a bug or you have an idea for a cool new feature? Contributing code is a great way to give something back to
|
|
the open source community. Before you dig right into the code there are a few guidelines that we need contributors to
|
|
follow so that we can have a chance of keeping on top of things.
|
|
|
|
Getting Started
|
|
---------------
|
|
|
|
+ Make sure you have a [JIRA account](https://issues.apache.org/jira/).
|
|
+ Make sure you have a [GitHub account](https://github.com/signup/free).
|
|
+ If you're planning to implement a new feature it makes sense to discuss you're changes on the [dev list](https://commons.apache.org/mail-lists.html) first. This way you can make sure you're not wasting your time on something that isn't considered to be in Apache Commons Math's scope.
|
|
+ Submit a ticket for your issue, assuming one does not already exist.
|
|
+ Clearly describe the issue including steps to reproduce when it is a bug.
|
|
+ Make sure you fill in the earliest version that you know has the issue.
|
|
+ Fork the repository on GitHub.
|
|
|
|
Making Changes
|
|
--------------
|
|
|
|
+ Create a topic branch from where you want to base your work (this is usually the master/trunk branch).
|
|
+ Make commits of logical units.
|
|
+ Respect the original code style:
|
|
+ Only use spaces for indentation.
|
|
+ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
|
|
+ Check for unnecessary whitespace with git diff --check before committing.
|
|
+ Make sure your commit messages are in the proper format. Your commit message should contain the key of the JIRA issue.
|
|
+ Make sure you have added the necessary tests for your changes.
|
|
+ Run all the tests with `mvn clean verify` to assure nothing else was accidentally broken.
|
|
|
|
Making Trivial Changes
|
|
----------------------
|
|
|
|
For changes of a trivial nature to comments and documentation, it is not always necessary to create a new ticket in JIRA.
|
|
In this case, it is appropriate to start the first line of a commit with '(doc)' instead of a ticket number.
|
|
|
|
Submitting Changes
|
|
------------------
|
|
|
|
+ Sign the [Contributor License Agreement][cla] if you haven't already.
|
|
+ Push your changes to a topic branch in your fork of the repository.
|
|
+ Submit a pull request to the repository in the apache organization.
|
|
+ Update your JIRA ticket and include a link to the pull request in the ticket.
|
