Cross-language distributed trace E2E test

qualify internal
6 files changed
  • test_cross_language_trace_e2e.py 201-line E2E test: TypeScript client sends W3C traceparent header, Python server continues the span — asserts trace_id/parent_id linkage
  • cross_language_server.py 94-line test server that extracts and echoes trace context
  • __init__.py Package init for E2E backends
  • e2e_cross_language_client.ts 104-line TypeScript E2E client that initiates the trace and sends the traceparent header
  • 2026-03-25-cross-language-distributed-tracing-e2e.md 583-line design and implementation doc for cross-language trace test
  • pyproject.toml Added E2E test dependencies and markers
  • E2E test validates W3C trace context propagation across language boundaries. TypeScript client sends a request with traceparent header; Python server extracts trace_id/parent_id from the incoming context and returns them. Test asserts the trace ID matches, confirming distributed trace linkage. qualify internal

Cross-signal isolation resilience test

qualify internal
1 file changed
  • test_cross_signal_isolation.py 137-line test: verifies that a log exporter timeout storm cannot starve the traces or metrics executor
  • Dedicated cross-signal isolation test exercises the scenario where log exports block continuously at timeout; asserts that traces and metrics workers continue to process their queues independently. qualify internal
