Contributing to the AWS SDK for PHP

Thank you for your interest in contributing to the AWS SDK for PHP! We work hard to provide a high-quality and useful SDK for our AWS services, and we greatly value feedback and contributions from our community. Whether it's a new feature, correction, or additional documentation, we welcome your pull requests. Please submit your issues or pull requests through GitHub.

How to contribute

Before you send us a pull request, please be sure that:

  1. You're working from the latest source on the master branch.
  2. You check existing open, and recently closed, pull requests to be sure that someone else hasn't already addressed the problem.
  3. You create an issue before working on a contribution that will take a significant amount of your time.

Creating a Pull Request

  1. Fork the repository.
  2. In your fork, make your change in a branch that's based on this repo's master branch.
  3. Commit the change to your fork, using a clear and descriptive commit message.
  4. Create a pull request, answering any questions in the pull request form.

For contributions that will take a significant amount of time, open a new issue to pitch your idea before you get started. Explain the problem and describe the content you want to see added to the documentation. Let us know if you'll write it yourself or if you'd like us to help. We'll discuss your proposal with you and let you know whether we're likely to accept it.

Bug Reports

Bug reports are accepted through the Issues page.

Before Submitting:

  • Do a search through the existing issues to make sure it has not already been reported. If it has, comment your experience or +1 so we prioritize it.
  • If possible, upgrade to the latest release of the SDK. It's possible the bug has already been fixed in the latest version.

Writing the Bug Report:

Please ensure that your bug report has the following:

  • A short, descriptive title. Ideally, other community members should be able to get a good idea of the issue just from reading the title.
  • A detailed description of the problem you're experiencing. This should include:
    • Expected behavior of the SDK and the actual behavior exhibited.
    • Any details of your application environment that may be relevant.
    • Debug information, stack trace or logs.
  • If you are able to create one, include a Minimal Working Example that reproduces the issue.
  • Use Markdown to make the report easier to read; i.e. use code blocks when pasting a code snippet.

Feature Requests

Open an [issue][] with the following:

  • A short, descriptive title. Ideally, other community members should be able to get a good idea of the feature just from reading the title.
  • A detailed description of the the proposed feature.
    • Why it should be added to the SDK.
    • If possible, example code to illustrate how it should work.
  • Use Markdown to make the request easier to read;
  • If you intend to implement this feature, indicate that you'd like to the issue to be assigned to you.

Code Contributions

Code contributions to the SDK are done through Pull Requests. The list below are guidelines to use when submitting pull requests. These are the same set of guidelines that the core contributors use when submitting changes, and we ask the same of all community contributions as well:

  1. The SDK is released under the Apache license. Any code you submit will be released under that license. For substantial contributions, we may ask you to sign a Contributor License Agreement (CLA).
  2. We follow all of the relevant PSR recommendations from the PHP Framework Interop Group. Please submit code that follows these standards. The PHP CS Fixer tool can be helpful for formatting your code.
  3. We maintain a high percentage of code coverage in our unit tests. If you make changes to the code, please add, update, and/or remove tests as appropriate. Tests are run via make test command.
  4. Static code analysis with PHPStan is automatically run on the src directory for submitted pull requests. If there is a case that needs to be ignored by static analysis, please update the ignoreErrors section in the phpstan.neon config file in your PR, and point out why this case warrants ignoring.
  5. We may choose not to accept pull requests that change files in the src/data directory, since we generate these files based on our internal knowledge of the AWS services. Please check in with us ahead of time if you find a mistake or missing feature that would affect those files.
  6. If your code does not conform to the PSR standards, does not include adequate tests, or does not contain a changelog document, we may ask you to update your pull requests before we accept them. We also reserve the right to deny any pull requests that do not align with our standards or goals.
  7. If you would like to implement support for a significant feature that is not yet available in the SDK, please talk to us beforehand to avoid any duplication of effort.
  8. We greatly appreciate contributions to our User Guide. The docs are written as a Sphinx website formatted with reStructuredText (very similar to Markdown). The User Guide is located in another repository. Please go to the awsdocs/aws-php-developers-guide.
    repository to suggest edits for the User Guide.
  9. If you are working on the SDK, make sure to check out the Makefile for some of the common tasks that we have to do.

Changelog Documents

A changelog document is a small JSON blob placed in the .changes/nextrelease folder. It should be named a clearly and uniquely, akin to a branch name. It consists of a type, category, and description as follows:

[
    {
        "type": "feature|enhancement|bugfix",
        "category": "Target of Update",
        "description": "English language simple description of your update."
    }
]

Changelog Types

  • feature - For major additive features, internal changes that have outward impact, or updates to the SDK foundations. This will result in a minor version change.
  • enhancement - For minor additive features or incremental sized changes. This will result in a patch version change.
  • bugfix - For minor changes that resolve an issue. This will result in a patch version change.
  • documentation - For updates to guides and documentation files only. This will result in a patch version change.

Changelog Categories

A changelog document's category field should correspond to a Service subfolder of the src directory. If your update is for core components of the SDK, the category field should exist with the value set to an empty string "".
