Add logging utility module by PerfectSlayer · Pull Request #10879 · DataDog/dd-trace-java

PerfectSlayer · 2026-03-17T20:00:20Z

What Does This Do

This PR introduces an :logging-utils module for RatelimitedLogger and IOLogger.
Additionally, Spock tests were migrated to JUnit.

Motivation

The goal is to move them away from the :internal-api module so they can be reused in various components without having to rely on the global internal APIs.

Additional Notes

The PR is split in 3 PR:

the 1st one creates the module (move of the existing code)
the 2nd one migrate the tests (dedicated commit to ease the review)
the 3rd one is the refactoring to use the new module instead of the class from internal API (again, to ease the review due to the multiple package updates needed)

Thanks for the fix!

Don't we have a gradle task for this case? Should it have been capture by CI?

FYI looking at the final dd-java-agent jar, two copies of RatelimitedLogger and IOLogger are ending up in the jar:
Don't we have a gradle task for this case? Should it have been capture by CI?

I recall we should have something like:

> Task :dd-java-agent:generateAgentJarIndex
[main] WARN datadog.trace.bootstrap.AgentJarIndex - Detected duplicate content 'dd-trace-core.version' under 'appsec', already seen in trace. Ensure your content is under a distinct directory.
.....

Or it is something different?
I like the idea to capture that on CI 👍

PerfectSlayer · 2026-03-18T14:13:34Z

Yeah, it remembers it too now.
I wonder too if it would be useful on CI or if it will flake 🤔 (but I can see why there should be other cases when we would allow it). Nonetheless, it's still useful to not break the build by default as you may want duplication when experimenting with refactoring.

We can show warnings on PRs and fail in Merge Queue?

PerfectSlayer · 2026-03-18T14:39:40Z

We can show warnings on PRs and fail in Merge Queue?

We already run different tasks on PR check vs MQ. So we can have a proper task that would fail we trigger on MQ pipelines only.

PerfectSlayer · 2026-03-18T16:04:14Z

adding this patch should fix the duplicate content:
