Contributions are always welcome. Before contributing please read the
code of conduct and search the issue tracker; your issue may have already been discussed or fixed in main. To contribute,
fork this repository, commit your changes, and send a Pull Request.
Note that our code of conduct applies to all platforms and venues related to this project; please follow it in all your interactions with the project and its participants.
Feature requests should be submitted in the Issue tracker, with a description of the expected behavior & use case, where they’ll remain closed until sufficient interest, e.g. 👍 reactions, has been shown by the community. Before submitting an Issue, please search for similar ones in the closed issues.
When contributing, keep in mind that New Relic customers (that's you!) are running many different versions of Java, some of them pretty old. Changes that require the newest version of Java will probably be rejected, especially if they replace something backwards compatible.
Be aware that the instrumentation needs to work with a wide range of versions of the instrumented modules, and that code that looks nonsensical or overcomplicated may be that way for compatibility-related reasons. Read all the comments and check the related tests before deciding whether existing code is incorrect.
If you’re planning on contributing a new feature or an otherwise complex contribution, we kindly ask you to start a conversation with the maintainer team by opening up a Github issue first.
As new dependencies have to be shaded and licensed for distribution, any additional dependency would have to add significant value.
- Use the style provided in the project.
- We encourage you to reduce tech debt you might find in the area. Leave the code better than you found it.
The tests can be run with ./gradlew test. Note that this runs unit tests, functional tests, and individual instrumentation module tests, so this is extremely time-consuming.
For more information, refer to the README.
We expect that all new code has robust unit test coverage, and any functional changes should also be covered by tests. Because the Java agent must support Java 7, we are using JUnit 4. We expect reasonable test coverage for any changed paths, but there’s no specific metric (such as through jacoco) at this time.
