Separate context tracking from tracing on http client instrumentations by amarziali · Pull Request #10782 · DataDog/dd-trace-java

amarziali · 2026-03-10T11:19:29Z

What Does This Do

Separates HTTP header injection (context propagation) from span lifecycle management by gating injectContext() calls behind ad-hoc context tracking advices.

It's mostly a Claude generated PR that I supervised.
