…5925) * create starlette package (#45754) - added type spec model generation - add model validator generation - creating a server * Lusu/response 0317 (#45757) * trying * generate contract models * add validator generator * fix model generation * add more unit tests * fix conflict * refined model generation * Lusu/response 0317 rename (#45764) * trying * generate contract models * add validator generator * fix model generation * add more unit tests * fix conflict * refined model generation * renamed the pacakge * response server apis (#45807) * create response * cancel and delete * fix options * remove old path * add samples * update pyproject * refining host * refined builders and hosting * refined package structur * remove unused code * add keep alive * fix minors * fix pytests * add file headers * add docstring for hosting * add conftest * add docstring * exclude scripts * add dev_requirement * fix build * fix build * fix generate models * fix pylint build * add ResponseIncompleteReason * refined stream * fix mypy * add ci * fix build * fix keyword * fix stream with background * ensure all contract cases covered * refined _rounting.py * fix stream payload * fix pylint * fix build * refining orchestrator * refining storing * add foundry storage provider * update response handler to decorator * remove dataclass * fix build * fix sphinx * try fix langchain-azure-ai version * Add agent server hosting and invocation packages (#45916) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Refactor responses package to leverage hosting for server hosting and route registration (#45921) Replace the standalone map_responses_server() function with a class-based ResponseHandler that plugs into AgentServer, following the same pattern as InvocationHandler. This enables multi-protocol composition, unified tracing via TracingHelper, automatic health probes, graceful shutdown delegation, and the x-platform-server identity header via hosting middleware. - Add ResponseHandler class with @create_handler decorator pattern - Integrate hosting's TracingHelper for OTel spans, W3C propagation, baggage - Fix Starlette 1.0.0 middleware compatibility in hosting _base.py - Add MultiProtocol sample showing both protocols on one AgentServer - Update all tests to use AgentServer + ResponseHandler pattern Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * [agentserver-responses] refining response orchestration (#45923) * use handler docorator and refining orchestration * refining orchestration * refined orchestration * fixed conflict and handler registration * [agentserver][responses] fix replay stuck (#45930) * use handler docorator and refining orchestration * refining orchestration * refined orchestration * fixed conflict and handler registration * fix replay * Lusu/response refining (#45936) * fixed docstirng. refined ResponseContext * refined context * add payload helpers * use dict for contract * Lusu/response refining (#45944) * fixed docstirng. refined ResponseContext * refined context * add payload helpers * use dict for contract * fix inmemory * fix helper and sample * rename -hosting to -core (#45946) * rename AgentHost (#45948) * Remove redundant default_fetch_history_count_value from ResponsesServerOptions Agent-Logs-Url: https://github.com/Azure/azure-sdk-for-python/sessions/eb08ee65-6dda-4937-ad91-45bb84a768cd Co-authored-by: lusu-msft <68949729+lusu-msft@users.noreply.github.com> * remove old -af and -lg from ci * fix multiprotocol sample * address PR #45925 review comments for -core and -invocations - Remove non-spec constants (AGENT_LOG_LEVEL, AGENT_GRACEFUL_SHUTDOWN_TIMEOUT) - Fix CHANGELOG: correct API names, add breaking changes section - Fix README env vars: add FOUNDRY_PROJECT_ARM_ID/SESSION_ID, remove non-spec - Wrap TracingHelper init in try/except for resilience - Add Python 3.14 classifier to pyproject.toml files - Move response header setting into try block for safety - Add input validation/sanitization for invocation_id and session_id - Add async function validation to handler decorators Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * add streaming and multi-turn invocation samples aligned to .NET - streaming_invoke_agent: SSE streaming with token-by-token output - multiturn_invoke_agent: session-based multi-turn conversations Aligns Python samples to the four .NET patterns: Sample1 (echo) -> simple_invoke_agent Sample2 (LRO) -> async_invoke_agent Sample3 (SSE) -> streaming_invoke_agent Sample4 (multi-turn) -> multiturn_invoke_agent Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * add FoundryEnrichmentSpanProcessor to enrich all spans with agent identity Register a span processor on the global TracerProvider so that gen_ai.agent.name, gen_ai.agent.version, gen_ai.agent.id, and microsoft.foundry.project.id are added to ALL spans — including those created by underlying frameworks (HTTP clients, LLM SDKs, etc.) — as required by the container image spec. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * resolving comments * [agentserver] remove nested methods in samples (#45977) * remove future import * remove nested funtion in samples * fix merge * fix apistub * update typespec and generated models * fix helper * remove output_message * rename health endpoint from /healthy to /readiness Per updated container spec, agentservice expects /readiness. Updated route, method name, docstrings, README, samples, and all tests across -core, -invocations, and -responses. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * update otel (#46003) * add _on_ending method to FoundryEnrichmentSpanProcessor The latest opentelemetry-sdk added _on_ending to the SpanProcessor interface, causing AttributeError at runtime. Add the required no-op method to fix compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * Implement S-047 (x-agent-response-id header) and S-048 (agent_session_id resolution and stamping) Agent-Logs-Url: https://github.com/Azure/azure-sdk-for-python/sessions/40114cbe-e583-4912-abc7-75c551a7e12c Co-authored-by: ankitbko <3169316+ankitbko@users.noreply.github.com> * Add unit tests for S-047 (Response ID Resolution) and S-048 (Session ID Resolution) Agent-Logs-Url: https://github.com/Azure/azure-sdk-for-python/sessions/40114cbe-e583-4912-abc7-75c551a7e12c Co-authored-by: ankitbko <3169316+ankitbko@users.noreply.github.com> * Add CHANGELOG.md, set __version__, remove wildcard import, fix README private imports, simplify model access in samples Agent-Logs-Url: https://github.com/Azure/azure-sdk-for-python/sessions/40114cbe-e583-4912-abc7-75c551a7e12c Co-authored-by: ankitbko <3169316+ankitbko@users.noreply.github.com> * Address code review feedback: clean up test, add comment for partition hint priority, add invalid header test Agent-Logs-Url: https://github.com/Azure/azure-sdk-for-python/sessions/40114cbe-e583-4912-abc7-75c551a7e12c Co-authored-by: ankitbko <3169316+ankitbko@users.noreply.github.com> * [response] update validator and minor fix (#46029) * update otel * refined readme * updated model validator * fix model * deleted MAF and langchain adapter * fixed broken tests * Replace static-method classes with module-level functions and add tracing dupe protection Thread 17: Replace ErrorResponse.create() with create_error_response() and AgentLogger.get() with get_logger() module-level functions. Updated all call sites across core, invocations, and responses packages. Thread 18: Added Breaking Changes section to CHANGELOG.md documenting the API renames, removed constants, and health endpoint rename. Thread 21: Added module-level sentinel flags to _setup_trace_export, _setup_log_export, _setup_otlp_trace_export, and _setup_otlp_log_export to prevent duplicate exporters across multiple TracingHelper instantiations. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Replace raw httpx with azure.core.AsyncPipelineClient in Foundry provider Migrated FoundryStorageProvider from raw httpx.AsyncClient to azure.core.AsyncPipelineClient, gaining built-in retry, logging, distributed tracing, and bearer-token authentication via AsyncBearerTokenCredentialPolicy. - Removed manual _auth_headers() — handled by pipeline policy - Removed http_client constructor parameter — pipeline is internal - Updated _foundry_errors.py to use azure.core.rest.HttpResponse - Removed httpx from pyproject.toml dependencies - Updated all unit tests to mock send_request instead of httpx methods Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Replace getattr(request, 'model', None) with request.model in README CreateResponse always has a model attribute, so the defensive getattr is unnecessary boilerplate. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove azure-ai-agentserver-responses from this PR Responses package has been split into a separate PR on the agentserver/responses branch for independent review and iteration. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Restore azure-ai-agentserver-agentframework and azure-ai-agentserver-langgraph from main These packages were inadvertently removed in an earlier commit. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix invoke_agent span parenting so framework child spans nest correctly (#46069) Add set_current_span/detach_context to TracingHelper so the invoke_agent span is attached as the active OTel context span. This ensures child spans created by framework handlers are parented under invoke_agent instead of appearing as siblings. - TracingHelper.set_current_span() attaches the span to context - TracingHelper.detach_context() restores the previous context - InvocationHandler propagates span_token through both streaming and non-streaming cleanup paths - Added test_span_parenting.py to verify parent-child relationship Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * added dev status inactive classifier * added log handler to root logger * Refactor AgentHost → AgentServerHost(Starlette) mixin inheritance Major architecture change per johanste's review: Core package: - Renamed AgentHost → AgentServerHost - Now inherits from Starlette directly (IS-A ASGI app) - Removed register_routes(), _build_app(), lazy app property - Routes, lifespan, and middleware set up in __init__ via super() - run()/run_async() use self as ASGI app Invocations package: - Renamed InvocationHandler → InvocationAgentServerHost - Now inherits from AgentServerHost - __init__ calls super() then extends self.routes - No more server parameter — this IS the server - Decorators are instance methods on the host User-facing API change: Before: server = AgentHost(); inv = InvocationHandler(server) After: app = InvocationAgentServerHost() Multi-protocol via diamond inheritance: class MyHost(InvocationHost, ResponsesHost): pass Updated all samples, READMEs, and tests. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Pass routes via super().__init__() instead of post-init mutation Routes are now collected by each mixin and passed up through super().__init__(routes=...) rather than appending to self.routes after construction. This avoids relying on Starlette's internal mutable routes list and ensures all routes are registered at Starlette initialization time. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Simplify _tracing.py: remove leaf_customer_span_id and baggage, fold methods Reduced _tracing.py from 1009 to 390 lines: - Removed leaf_customer_span_id baggage mechanism (_parse_baggage_key, _override_parent_span_id, _extract_context baggage override) - Removed set_baggage/detach_baggage/set_current_span/detach_context - Replaced start_request_span + manual context with request_span(end_on_exit=False) using start_as_current_span — child spans are correctly parented - Folded span_name, build_span_attrs, _prepare_request_span_args, span(), start_span() into a single request_span() context manager - TracingHelper public API is now: request_span, end_span, record_error, trace_stream - Updated invocations to use simplified tracing (removed baggage_token, span_token) - Removed baggage constants from InvocationConstants - Removed _parse_baggage_key tests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Fix span parenting tests: use TestClient instead of ASGITransport Starlette's TestClient runs synchronously in the same thread context, so OTel ContextVar propagation works correctly. HTTPX's ASGITransport runs the ASGI app in a different async context where ContextVars don't propagate, causing span parenting to break in tests only.
