Why

Dynamo request tracing writes request trace segments locally. NVCF needs a focused uploader image with a durable, testable foundation before the existing deployment script can be replaced.

What changed

  • Adds the build-only request-trace-uploader Go service and OCI image target.
  • Preserves the current trace and audit segment naming contract, active-segment exclusion, local health endpoints, and bounded upload policy configuration.
  • Adds a typed upload-client boundary plus scan, metric, configuration, and local-readiness tests. The initial implementation neither submits data nor deletes segments.
  • Adds REQUEST_TRACE_UPLOADER_DROP_NCA_IDS, a normalized audit payload drop list. It retains minimal correlation records for matches when the future transform is added; it does not drop segments or modify data in this scaffold.

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

  • go test ./... from src/compute-plane-services/request-trace-uploader
  • bazel test //src/compute-plane-services/request-trace-uploader/...
  • bazel build //src/compute-plane-services/request-trace-uploader/cmd:image

Notes

Follow-up work will add the supported S3 client, durable state transitions, and deployment wiring. The current script remains the production uploader. The future transform must carry a matching request drop decision to later response records that omit an NCA header.

References

Closes #1004

Related Pull Requests

None.

Dependencies

Uses the repository-standard github.com/prometheus/client_golang v1.23.2. Its Apache-2.0 license is already represented in repository dependency notices; no NOTICE update is needed.

Summary by CodeRabbit

  • New Features

    • Added a request-trace uploader service scaffold with configurable startup validation, health and readiness endpoints, Prometheus metrics, segment discovery, and graceful shutdown.
    • Added support for identifying closed trace and audit segments while excluding active segments.
    • Added container packaging and Bazel build/test integration.
  • Documentation

    • Added operational documentation covering configuration, supported segments, readiness behavior, build commands, and sensitive-data logging restrictions.

📝 Walkthrough

Walkthrough

Added the initial request-trace-uploader Go sidecar scaffold. It validates configuration, discovers closed trace and audit segments, exposes health and Prometheus endpoints, tracks discovery state, and builds a Bazel-managed OCI image. Upload and deletion remain unimplemented.

Changes

Request Trace Uploader

Layer / File(s) Summary
Configuration contract
src/compute-plane-services/request-trace-uploader/go.mod, src/compute-plane-services/request-trace-uploader/internal/config/*
Added environment-based configuration, validation, defaults, retry policies, NCA ID normalization, warnings, and tests.
Segment discovery and upload boundary
src/compute-plane-services/request-trace-uploader/internal/segment/*, src/compute-plane-services/request-trace-uploader/internal/upload/*
Added trace and audit segment discovery that excludes active segments. Added the upload client interface and status types without an implementation.
Health and metrics endpoints
src/compute-plane-services/request-trace-uploader/internal/health/*, src/compute-plane-services/request-trace-uploader/internal/metrics/*
Added readiness and liveness handlers and bounded Prometheus metrics with registration and exposition tests.
Service initialization and runtime
src/compute-plane-services/request-trace-uploader/internal/service/*
Added directory and secrets validation, discovery refresh, readiness changes, HTTP endpoints, periodic refresh, shutdown handling, and integration tests.
Executable, image, and repository integration
.github/workflows/bazel.yml, go.work.bazel, src/compute-plane-services/request-trace-uploader/{AGENTS.md,BUILD.bazel,CLAUDE.md,README.md}, src/compute-plane-services/request-trace-uploader/cmd/*
Added Bazel workspace and CI integration, project guidance, executable startup handling, and a distroless_go OCI image target.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to 2f7cc

The PR adds a new request-trace uploader service without deploying it or changing the current production uploader. Before activation, the service should add HTTP connection timeouts and required request telemetry to avoid resource exhaustion and improve diagnosis; merge is reasonable with explicit owner follow-up.

Instrument the uploader HTTP endpoints.

The new /livez, /readyz, and /metrics handlers are served without structured request logs, tracing, or bounded RED metrics. Add the repository-standard instrumentation at the service boundary and cover it with tests, without logging request bodies, credentials, or unbounded identifiers.

golangci-lint noctx analyzer httptest.NewRequest NewRequestWithContext

💡 Result:

The noctx linter in golangci-lint enforces the use of context-aware functions when performing HTTP operations [1][2]. Specifically, for httptest.NewRequest, the linter requires the use of httptest.NewRequestWithContext to ensure that requests are associated with a context.Context [3][4]. When noctx is enabled, it flags calls to httptest.NewRequest with the message: "must not be called. use net/http/httptest.NewRequestWithContext" [3]. Similarly, it flags net/http.NewRequest in favor of net/http.NewRequestWithContext [3]. To resolve these linter warnings, you should replace the standard constructors with their context-aware counterparts: 1. Replace httptest.NewRequest(method, target, body) with httptest.NewRequestWithContext(ctx, method, target, body) [3]. 2. Replace http.NewRequest(method, url, body) with http.NewRequestWithContext(ctx, method, url, body) [3][5]. If you encounter these warnings in test files where you prefer to use a simple context.Background(), you have a few options: - Update the code to use the context-aware variant explicitly (recommended) [4][5]. - If you specifically want to ignore these warnings in test files, you can configure an exclude-rule in your .golangci.yml file [6]: yaml issues: exclude-rules: - path: _test\.go linters: - noctx The noctx linter has been updated periodically to cover more functions, such as the addition of httptest.NewRequestWithContext detection in recent versions [7]. Using the context-aware versions is considered a best practice in Go to ensure proper cancellation and timeout propagation for network requests [1][3].

Use context-aware test requests in all five service tests.

Replace the three calls in health_test.go, the call in metrics_test.go, and the call in service_test.go with httptest.NewRequestWithContext(context.Background(), ...). Add the required context imports.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the discovery result through the metrics endpoint.

The test creates a closed segment and an active segment, but it only checks HTTP status codes. It passes if Refresh includes the active segment or fails to update backlog metrics. Assert that /metrics reports one pending segment after initialization.

Add operation context when propagating service errors.

These boundaries return errors without identifying the failed service operation. Wrap each error with %w and concise context. This preserves the originating error and makes startup and discovery failures actionable.

Set HTTP server timeouts.

Without timeout fields, clients can hold HTTP connections indefinitely. Configure ReadHeaderTimeout, ReadTimeout, WriteTimeout, and IdleTimeout to bound resource use.

Proposed fix
-	server := &http.Server{Addr: s.config.MetricsAddr, Handler: s.Handler()}
+	server := &http.Server{
+		Addr:              s.config.MetricsAddr,
+		Handler:           s.Handler(),
+		ReadHeaderTimeout: 5 * time.Second,
+		ReadTimeout:       15 * time.Second,
+		WriteTimeout:      15 * time.Second,
+		IdleTimeout:       60 * time.Second,
+	}
