feat: add nested phase spans for OpenTelemetry tracing#323
Merged
Conversation
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 <no-reply@ona.com>

CompositeReporter didn't implement PhaseAwareReporter, so the type assertion in executeBuildPhase failed silently and phase spans were never created. Co-authored-by: Ona <no-reply@ona.com>
Phase spans were nesting under each other because the package context was being updated to the phase context. Keep the original package context so all phases are direct children of the package span. Co-authored-by: Ona <no-reply@ona.com>
Track phase contexts so GetPackageContext returns the active phase context when a phase is running. This ensures child operations like go test tracing create spans under the test phase span. Co-authored-by: Ona <no-reply@ona.com>
SBOM phase was handled inline without calling PhaseAwareReporter. Co-authored-by: Ona <no-reply@ona.com>

Description
Add individual spans for each build phase (prep, pull, lint, test, build, package) as children of package spans. This enables detailed timeline visualization in tracing backends to identify which phases are slow.
