Contributing to Envoy

Looking to contribute something to Envoy? Here's how you can help.

Please take a moment to review this document in order to make the contribution process easy and effective for everyone involved.

Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue or assessing patches and features.

Using the issue tracker

The issue tracker is the preferred channel for bug reports, features requests and submitting pull requests, but please respect the following restrictions:

  • Please do not derail or troll issues. Keep the discussion on topic and respect the opinions of others.

  • Please do not post comments consisting solely of "+1" or "👍". Use GitHub's "reactions" feature instead. We reserve the right to delete comments which violate this rule.

    However, as we know, we are all software engineers that like being funny hence doing it on purpose. Please also refrain from that kind of behaviour.

Issues and labels

Our bug tracker utilizes several labels to help organize and identify issues. Here's what they represent and how we use them:

  • Documentation & Javadoc- Issues regarding the documentation of Envoy
  • Enhancement & Feature - Issues suggesting a new feature
  • Maven - Issues concerned with Maven problems
  • Bug - Issues concerned with a general bug

For a complete look at our labels, see the project labels page.

Bug reports

A bug is a demonstrable problem that is caused by the code in the repository. Good bug reports are extremely helpful, so thanks!

Guidelines for bug reports:

  1. ensure your problem isn't caused by a simple error in your own code.

  2. Use the GitHub issue search — check if the issue has already been reported.

  3. Check if the issue has been fixed — try to reproduce it using the latest master or development branch in the repository.

  4. Isolate the problem — ideally create a reduced test case and a live example.

A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? These details will help people to fix any potential bugs.

Example:

Short and descriptive example bug report title

  1. This is the first step
  2. This is the second step
  3. Further steps, etc.

Any other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).

Feature requests

Feature requests are welcome. But take a moment to find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Please provide as much detail and context as possible.

Pull requests

Good pull requests—patches, improvements, new features—are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.

Please ask first before embarking on any significant pull request (e.g. implementing features, refactoring code, porting to a different language), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.

Please adhere to the coding guidelines used throughout the project (indentation, accurate comments, etc.) and any other requirements (such as test coverage).

Adhering to the following process is the best way to get your work included in the project:

  1. Download, clone or Fork the project, using https://github.com/informatik-ag-ngl/envoy-common/as Remote.

  2. If you cloned a while ago, get the latest changes from upstream:

    git checkout master
    git pull upstream master
    

    Or, if your IDE of choice supports this, simply use pull

  3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:

    git checkout -b <topic-branch-name>
    

    Or, simply use "New branch" if your IDE supports this

  4. Commit your changes in logical chunks. Please adhere to these git commit message guidelines or your code is unlikely be merged into the main project. Use Git's interactive rebase feature to tidy up your commits before making them public.

  5. Locally merge (or rebase) the upstream development branch into your topic branch:

    git pull [--rebase] upstream master
    
  6. Push your topic branch up to your fork:

    git push origin <topic-branch-name>
    
  7. Open a Pull Request with a clear title and description against the master branch.

Code guidelines

Java

Please use the formatter provided with this project. Especially before saving. For best results, select the option "format code" in the "Save Actions" tab in Preferences in Eclipse, so that you never accidentally forget it. Every public function (not annotated with @Override) must be delivered with Javadoc. For best project-appropriate Javadoc please take a look at the other functions which are all already equipped with Javadoc.
