Add suffix ID to memfd file name #9796

raphaelgavache · 2025-10-17T15:34:01Z

What Does This Do

Fix the memfd name to include a 8 byte suffix following spec. This suffix is going to be used by the agent for: DataDog/datadog-agent#41742

Matching system-test PR that passes with this java tracer DataDog/system-tests#5545
with failing system-test against current java latest commit

>           assert match, f"invalid file format: {out}"
E           AssertionError: invalid file format: /memfd:datadog-tracer-info- (deleted)
E             
E           assert None
