From aa8c20c9c6e6f97f383599a96b3008ff5587088b 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 b7b11b7b..6aad8e8c 100644 --- a/README.md +++ b/README.md @@ -593,6 +593,63 @@ 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 a64253c24eb8798db348895edba71dae3a81dded Mon Sep 17 00:00:00 2001 From: "Cornelius A.

Ludmann" Date: Tue, 25 Nov 2025 15:27:14 +0000 Subject: [PATCH 13/13] feat: add nested phase spans for OpenTelemetry tracing Add PhaseAwareReporter optional interface to enable phase-level span creation without breaking existing reporters. Phase spans are created as children of package spans for detailed build timeline visualization. Changes: - Define PhaseAwareReporter interface with phase start/finish methods - Implement phase span tracking in OTelReporter - Modify executeBuildPhase to call phase-aware reporters via type assertion - Remove phase duration attributes (now captured in nested spans) - Add comprehensive phase span tests - Update documentation with span hierarchy and phase attributes Closes CLC-2107 Co-authored-by: Ona --- README.md | 17 ++ docs/observability.md | 28 ++- pkg/leeway/build.go | 10 + pkg/leeway/reporter.go | 87 ++++++- pkg/leeway/reporter_otel_phase_test.go | 329 +++++++++++++++++++++++++ pkg/leeway/reporter_otel_test.go | 55 ++--- 6 files changed, 485 insertions(+), 41 deletions(-) create mode 100644 pkg/leeway/reporter_otel_phase_test.go diff --git a/README.md b/README.md index 7d4141c7..a8759082 100644 --- a/README.md +++ b/README.md @@ -613,6 +613,23 @@ leeway build :my-package The OpenTelemetry SDK automatically reads standard `OTEL_EXPORTER_OTLP_*` environment variables. +## Span Hierarchy + +Leeway creates a nested span hierarchy for detailed build timeline visualization: + +``` +leeway.build (root) +├── leeway.package (component:package-1) +│ ├── leeway.phase (prep) +│ ├── leeway.phase (build) +│ └── leeway.phase (test) +└── leeway.package (component:package-2) + ├── leeway.phase (prep) + └── leeway.phase (build) +``` + +Each phase span captures timing, status, and errors for individual build phases (prep, pull, lint, test, build, package). + **For detailed configuration, examples, and span attributes, see [docs/observability.md](docs/observability.md).** # Provenance (SLSA) - EXPERIMENTAL diff --git a/docs/observability.md b/docs/observability.md index 8a02c441..29561488 100644 --- a/docs/observability.md +++ b/docs/observability.md @@ -19,14 +19,24 @@ OpenTelemetry tracing in leeway captures: ``` Root Span (leeway.build) ├── Package Span 1 (leeway.package) +│ ├── Phase Span (leeway.phase: prep) +│ ├── Phase Span (leeway.phase: pull) +│ ├── Phase Span (leeway.phase: lint) +│ ├── Phase Span (leeway.phase: test) +│ ├── Phase Span (leeway.phase: build) +│ └── Phase Span (leeway.phase: package) ├── Package Span 2 (leeway.package) +│ ├── Phase Span (leeway.phase: prep) +│ └── Phase Span (leeway.phase: build) └── Package Span N (leeway.package) + └── ... ``` - **Root Span**: Created when `BuildStarted` is called, represents the entire build operation - **Package Spans**: Created for each package being built, as children of the root span +- **Phase Spans**: Created for each build phase (prep, pull, lint, test, build, package) as children of package spans -Build phase durations (prep, pull, lint, test, build, package) are captured as attributes on package spans, not as separate spans. +Phase spans provide detailed timeline visualization and capture individual phase errors.
