`@src/compute-plane-services/request-trace-uploader/internal/health/health_test.go`:
- Around line 15-26: Update the three httptest.NewRequest calls in
health_test.go, the call at metrics_test.go:28, and the call in service_test.go
to use httptest.NewRequestWithContext(context.Background(), ...), adding context
imports where needed. Preserve each request’s existing method, URL, and body.
In
`@src/compute-plane-services/request-trace-uploader/internal/service/service_test.go`:
- Around line 24-29: Update the test covering the closed and active
request-trace segments to query the /metrics endpoint after initialization and
assert that the pending-segment metric reports exactly one. Keep the existing
HTTP status checks while verifying the discovery result through the metrics
response.
In
`@src/compute-plane-services/request-trace-uploader/internal/service/service.go`:
- Around line 36-38: Update the error returns in the service initialization and
discovery paths, including the metrics.New call and the locations corresponding
to lines 72-73, 81-83, and 111-112, to wrap each underlying error with %w and
concise operation-specific context while preserving the original errors.
- Around line 114-120: Configure ReadHeaderTimeout, ReadTimeout, WriteTimeout,
and IdleTimeout on the http.Server created in the service startup flow before
ListenAndServe runs, using the service’s established timeout configuration or
appropriate bounded durations.

135-138: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winStop the HTTP server before returning on refresh failure.
If
s.Refresh()fails afterListenAndServe()starts,Runreturns but leaves the listener goroutine active. The health endpoint can continue to report ready state, and the caller cannot safely reuse the configured address.Set readiness false and shut down the server with a bounded context before returning the refresh error. Add a regression test that verifies the listener closes after a periodic refresh failure.
As per path instructions, add tests for code changes.

- Around line 143-151: Update the HTTP server construction in Service.httpServer
to wrap the existing Handler with route-normalized middleware for health and
metrics endpoints, providing structured request logs, tracing, and bounded
nvcf_* RED metrics. Use stable route labels rather than raw request paths or
request-derived data, and preserve the existing timeout settings and handler
behavior.

Why
Dynamo request tracing writes request-trace segments locally. NVCF needs a focused uploader image with a testable foundation before the existing deployment script can be replaced.
What changed
request-trace-uploaderGo service and OCI image target.REQUEST_TRACE_UPLOADER_DROP_NCA_IDS, a normalized audit payload drop-list configuration. The future transform will apply it; this scaffold does not alter records./metricsroute. The remaining listener is health-only and usesHEALTH_ADDR.Customer Release Notes
Not customer visible.
Plan Summary
Not applicable. The image is build-only. No release registration, publishing configuration, workload sidecar injection, or deployment rollout is included.
Usage
Build the image target with
bazel build //src/compute-plane-services/request-trace-uploader/cmd:image.Testing
GOWORK=off GOCACHE=/private/tmp/request-trace-uploader-go-cache go test ./...fromsrc/compute-plane-services/request-trace-uploaderbazel --output_user_root=/private/tmp/nvcf-request-trace-uploader-bazel test //src/compute-plane-services/request-trace-uploader/...Notes
The existing script remains the production uploader. Later work is split under #1004: direct BYOO OTLP logs, traces, and metrics in #1046; initial S3 upload in #1047; durable lifecycle in #1050; configurable policy in #1051; NCA payload drop transform in #1048; documentation in #1052; and future NVCA injection in #1049.
References
Relates to #1004

Dependencies
