Contributing to the PHP Library for MongoDB

Initializing the Repository

Developers who would like to contribute to the library will need to clone it and initialize the project dependencies with Composer:

$ git clone https://github.com/mongodb/mongo-php-library.git
$ cd mongo-php-library
$ composer update

In addition to installing project dependencies, Composer will check that the required extension version is installed. Directions for installing the extension may be found here.

Installation directions for Composer may be found in its Getting Started guide.

Testing

The library's test suite uses PHPUnit, which should be installed as a development dependency by Composer.

The test suite may be executed with:

$ vendor/bin/phpunit

The phpunit.xml.dist file is used as the default configuration file for the test suite. In addition to various PHPUnit options, it defines required MONGODB_URI and MONGODB_DATABASE environment variables. You may customize this configuration by creating your own phpunit.xml file based on the phpunit.xml.dist file we provide.

Testing on HHVM

By default, the PHPUnit script relies on the php interpreter for your shell (i.e. #!/usr/bin/env php). You can run the test suite with HHVM like so:

$ hhvm vendor/bin/phpunit

Documentation

Documentation for the library lives in the docs/ directory and is built with tools in the related mongodb/docs-php-library repository. The tools repository is already configured to reference our sources.

That said, any changes to the documentation should be tested locally before committing. Follow the following steps to build the docs locally with the tools repository:

  • Clone the mongodb/docs-php-library tools repository.
  • Install giza, as noted in the tools README.
  • Sync your working copy of the documentation to the source/ directory with rsync -a --delete /path/to/mongo-php-library/docs/ source/.
  • Build the documentation with giza make publish. You can suppress informational log messages with the --level warning option.
  • Generated documentation may be found in the build/master/html directory.

Releasing

The follow steps outline the release process for a maintenance branch (e.g. releasing the vX.Y branch as X.Y.Z).

Ensure PHP version compatibility

Ensure that the library test suite completes on supported versions of PHP and HHVM.

Transition JIRA issues and version

All issues associated with the release version should be in the "Closed" state and have a resolution of "Fixed". Issues with other resolutions (e.g. "Duplicate", "Works as Designed") should be removed from the release version so that they do not appear in the release notes.

Check the corresponding ".x" fix version to see if it contains any issues that are resolved as "Fixed" and should be included in this release version.

Update the version's release date and status from the Manage Versions page.

Update version info

The PHP library uses semantic versioning. Do not break backwards compatibility in a non-major release or your users will kill you.

Before proceeding, ensure that the master branch is up-to-date with all code changes in this maintenance branch. This is important because we will later merge the ensuing release commits up to master with --strategy=ours, which will ignore changes from the merged commits.

A version constant may be added at a later date (see: PHPLIB-131). For now, there is nothing to update.

Tag release

The maintenance branch's HEAD will be the target for our release tag:

$ git tag -a -m "Release X.Y.Z" X.Y.Z

Push tags

$ git push --tags

Merge the maintenance branch up to master

$ git checkout master
$ git merge vX.Y --strategy=ours
$ git push

The --strategy=ours option ensures that all changes from the merged commits will be ignored.

Publish release notes

The following template should be used for creating GitHub release notes via this form.

The PHP team is happy to announce that version X.Y.Z of our MongoDB PHP library is now available. This library is a high-level abstraction for the PHP 5, PHP 7, and HHVM drivers (i.e. [`mongodb`](http://php.net/mongodb) extension).
