Framework spans created inside handlers are now parented directly under the caller's span. Changes: - core/_tracing.py: Add request_context(), remove request_span() - core/_base.py: Simplify AgentServerHost.request_context() wrapper - invocations/_invocation.py: Remove span creation/attrs/end logic - responses/_endpoint_handler.py: Same simplification - Remove agent_type from enrichment processor (no invoke_agent span) - Update all tests to validate context propagation without server span Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../azure/ai/agentserver/core/_base.py | 47 +-- .../azure/ai/agentserver/core/_tracing.py | 110 ++----- .../selfhosted_invocation.py | 8 +- .../tests/test_tracing.py | 62 ---- .../tests/test_tracing_e2e.py | 168 ++++------- .../ai/agentserver/invocations/_invocation.py | 101 +------ .../tests/test_span_parenting.py | 90 +++--- .../tests/test_tracing.py | 277 +++++------------- .../responses/hosting/_endpoint_handler.py | 133 +-------- .../tests/contract/test_tracing.py | 46 ++- 10 files changed, 240 insertions(+), 802 deletions(-) diff --git a/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/_base.py b/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/_base.py index 44bacb0b86a9..6625a6cf2d1a 100644 --- a/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/_base.py +++ b/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/_base.py @@ -328,55 +328,24 @@ def _build_server_version(self) -> str: # Tracing (for protocol subclasses) # ------------------------------------------------------------------ - #: Default instrumentation scope for tracing spans. - #: Protocol subclasses should override this per the spec. - _INSTRUMENTATION_SCOPE = "Azure.AI.AgentServer" - @contextlib.contextmanager - def request_span( + def request_context( self, headers: Any, - request_id: str, - operation: str, - *, - operation_name: Optional[str] = None, - session_id: str = "", - end_on_exit: bool = True, ) -> Any: - """Create a request-scoped span with this host's identity attributes. + """Extract W3C trace context and attach as the current OTel context. - Delegates to :func:`_tracing.request_span` with pre-populated - agent identity from environment variables. + Delegates to :func:`_tracing.request_context`.

This caused the first E2E test to always fail in CI. Fix: Add a session-scoped autouse fixture that sends a dummy span and polls until App Insights confirms ingestion (up to 360s). Real tests then run against a 'warm' pipeline with fast ingestion. Also restores test_handler_span_in_appinsights which is no longer flaky.
