From 34d7a7b7edda3deb9133fbcaa1cedbc62db154d0 Mon Sep 17 00:00:00 2001 From: "Cornelius A. Ludmann" Date: Thu, 20 Nov 2025 16:04:27 +0000 Subject: [PATCH 01/13] feat: add OpenTelemetry tracing with build and package spans Add OpenTelemetry infrastructure for distributed tracing with support for W3C Trace Context propagation from CI systems. - Add telemetry package with tracer initialization, shutdown, and trace context parsing - Implement OTelReporter with build and package span creation - Add CLI flags: --otel-endpoint, --trace-parent, --trace-state - Capture build metrics, package timing, and GitHub Actions context - Thread-safe concurrent package builds with RWMutex - Graceful degradation when tracing fails - Comprehensive tests with in-memory exporters - Documentation in docs/observability.md and README.md Closes CLC-2106 Co-authored-by: Ona --- README.md | 57 +++++ cmd/build.go | 51 +++++ docs/README.md | 1 + docs/observability.md | 258 +++++++++++++++++++++ go.mod | 10 +- pkg/leeway/reporter.go | 256 +++++++++++++++++++++ pkg/leeway/reporter_otel_test.go | 340 ++++++++++++++++++++++++++++ pkg/leeway/telemetry/tracer.go | 182 +++++++++++++++ pkg/leeway/telemetry/tracer_test.go | 189 ++++++++++++++++ 9 files changed, 1341 insertions(+), 3 deletions(-) create mode 100644 docs/README.md create mode 100644 docs/observability.md create mode 100644 pkg/leeway/reporter_otel_test.go create mode 100644 pkg/leeway/telemetry/tracer.go create mode 100644 pkg/leeway/telemetry/tracer_test.go diff --git a/README.md b/README.md index 2e70d4ae..a5f182fd 100644 --- a/README.md +++ b/README.md @@ -598,6 +598,63 @@ variables have an effect on leeway: - `LEEWAY_YARN_MUTEX`: Configures the mutex flag leeway will pass to yarn.

This improves testability and follows separation of concerns. Changes: - InitTracer now takes endpoint as parameter: InitTracer(ctx, endpoint) - Remove confusing env var manipulation in cmd/build.go - Simplify test (no need to manipulate environment) - Make configuration flow clearer: flag → function parameter Benefits: - Easier to test (no env var side effects) - Clearer API (explicit parameter vs implicit env var) - Consistent with other reporters (e.g., SegmentReporter) - No circular dependency between flag default and env var Co-authored-by: Ona --- cmd/build.go | 9 ++------- pkg/leeway/telemetry/tracer.go | 7 +++---- pkg/leeway/telemetry/tracer_test.go | 13 ++----------- 3 files changed, 7 insertions(+), 22 deletions(-) diff --git a/cmd/build.go b/cmd/build.go index 91c23ec8..1dc54323 100644 --- a/cmd/build.go +++ b/cmd/build.go @@ -325,13 +325,8 @@ func getBuildOpts(cmd *cobra.Command) ([]leeway.BuildOption, cache.LocalCache, f if otelEndpoint, err := cmd.Flags().GetString("otel-endpoint"); err != nil { log.Fatal(err) } else if otelEndpoint != "" { - // Set environment variable for InitTracer if not already set - if os.Getenv("OTEL_EXPORTER_OTLP_ENDPOINT") == "" { - os.Setenv("OTEL_EXPORTER_OTLP_ENDPOINT", otelEndpoint) - } - - // Initialize tracer - tp, err := telemetry.InitTracer(context.Background()) + // Initialize tracer with the provided endpoint + tp, err := telemetry.InitTracer(context.Background(), otelEndpoint) if err != nil { log.WithError(err).Warn("failed to initialize OpenTelemetry tracer") } else { diff --git a/pkg/leeway/telemetry/tracer.go b/pkg/leeway/telemetry/tracer.go index ab11433c..69dce2ad 100644 --- a/pkg/leeway/telemetry/tracer.go +++ b/pkg/leeway/telemetry/tracer.go @@ -17,12 +17,11 @@ import ( ) // InitTracer initializes the OpenTelemetry tracer with OTLP HTTP exporter. -// It reads the OTEL_EXPORTER_OTLP_ENDPOINT environment variable for the endpoint. +// The endpoint parameter specifies the OTLP endpoint URL (e.g., "localhost:4318"). // Returns the TracerProvider which must be shut down when done. -func InitTracer(ctx context.Context) (*sdktrace.TracerProvider, error) { - endpoint := os.Getenv("OTEL_EXPORTER_OTLP_ENDPOINT") +func InitTracer(ctx context.Context, endpoint string) (*sdktrace.TracerProvider, error) { if endpoint == "" { - return nil, xerrors.Errorf("OTEL_EXPORTER_OTLP_ENDPOINT not set") + return nil, xerrors.Errorf("OTLP endpoint not provided") } // Create OTLP HTTP exporter diff --git a/pkg/leeway/telemetry/tracer_test.go b/pkg/leeway/telemetry/tracer_test.go index 9ba00502..4eb5ed78 100644 --- a/pkg/leeway/telemetry/tracer_test.go +++ b/pkg/leeway/telemetry/tracer_test.go @@ -2,7 +2,6 @@ package telemetry import ( "context" - "os" "testing" "go.opentelemetry.io/otel/trace" @@ -168,17 +167,9 @@ func TestFormatTraceContext_Invalid(t *testing.T) { } func TestInitTracer_NoEndpoint(t *testing.T) { - // Save and restore environment - oldEndpoint := os.Getenv("OTEL_EXPORTER_OTLP_ENDPOINT") - defer func() { - _ = os.Setenv("OTEL_EXPORTER_OTLP_ENDPOINT", oldEndpoint) - }() - - _ = os.Unsetenv("OTEL_EXPORTER_OTLP_ENDPOINT") - - _, err := InitTracer(context.Background()) + _, err := InitTracer(context.Background(), "") if err == nil { - t.Error("InitTracer() should fail when OTEL_EXPORTER_OTLP_ENDPOINT is not set") + t.Error("InitTracer() should fail when endpoint is empty") } } From cace799cc9557216a144a88774b248e505bd327d Mon Sep 17 00:00:00 2001 From: "Cornelius A.
