How to contribute to Phinx

Phinx relies heavily on external contributions in order to make it the best database migration tool possible. Without the support of our 130+ contributors, we wouldn't be where we are today! We encourage anyone to submit documentation enhancements and code.

Issues, feature requests, and bugs should be submitted using the Github issue tool: https://github.com/cakephp/phinx/issues.

This document briefly outlines the requirements to contribute code to Phinx.

Considerations

Before you submit your pull request take a moment to answer the following questions.

Answering 'YES' to all questions will increase the likelihood of your PR being accepted!

  • Have I implemented my feature for as many database adapters as possible?
  • Does my new feature improve Phinx's performance or keep it consistent?
  • Does my feature fit within the database migration space?
  • Is the code entirely my own and free from any commercial licensing?
  • Am I happy to release my code under the MIT license?
  • Is my code formatted using the PSR-2 coding standard?

Note: We accept bug fixes much faster into our development branch than new features.

Getting Started

Great, so you want to contribute. Let's get started:

  1. Start by forking Phinx on GitHub: https://github.com/cakephp/phinx

  2. Clone your repository to a local directory on your development box.

  3. If you do not have Composer set up already, install it:

    curl -sS https://getcomposer.org/installer | php

  4. Change to your Phinx clone directory and pull the necessary dependencies:

    php composer.phar install

  5. Copy the phpunit.xml.dist template to phpunit.xml:

    cp phpunit.xml.dist phpunit.xml

    And change the configuration to suit your environment. If you are not using any particular adapter you can disable it in the phpunit.xml file.

  6. Run the unit tests locally to ensure they pass:

    php vendor/bin/phpunit --config phpunit.xml

  7. Write the code and unit tests for your bug fix or feature.

  8. Add any relevant documentation.

  9. Run the unit tests again and ensure they pass.

  10. Open a pull request on the Github project page. Ensure the code is being merged into master.

Getting Started with docker

If you do not wish to install MySQL and Postgres locally to run unit tests install docker-compose for your platform.

  1. Download all images, build and start development container:

    docker-compose run --rm phinx

  2. Install dependencies:

    composer update

  3. Run unittest:

    vendor/bin/phpunit

Documentation

The Phinx documentation is stored in the docs directory using the RestructedText format. All documentation merged to master is automatically published to the Phinx documentation site available at http://docs.phinx.org.
