From 47e13d9dc5b590f15793bd3ab3d9804edc492452 Mon Sep 17 00:00:00 2001 From: waadarsh Date: Sun, 31 May 2026 16:43:10 +0530 Subject: [PATCH 1/2] feat(a2a): upgrade a2a-sdk dependency from >=0.3.4,<0.4 to >=1.0,<2 Migrates all A2A integration code and tests from the Pydantic-based a2a-sdk 0.3.x API to the Protocol Buffer (proto) based a2a-sdk 1.x API, implementing the A2A 1.0 specification. Breaking changes addressed: - Part types: TextPart/DataPart/FilePart replaced by flat proto Part with WhichOneof("content") oneof pattern (text, url, raw, data) - Enum prefixes: TaskState.working -> TASK_STATE_WORKING, Role.agent -> ROLE_AGENT (all enums now SCREAMING_SNAKE_CASE) - Timestamps: TaskStatus.timestamp is now proto Timestamp (use .FromDatetime() instead of .isoformat() string) - TaskStatusUpdateEvent.final field removed; finality via task state - AgentCard.url moved to supported_interfaces list (AgentInterface) with protocolBinding + protocolVersion fields (A2A 1.0 schema) - A2AStarletteApplication removed; replaced by create_agent_card_routes(), create_jsonrpc_routes(), create_rest_routes() builders - DefaultRequestHandler now requires agent_card= constructor argument - ClientCallContext moved: a2a.client.middleware -> a2a.client.client - ClientConfig.supported_transports -> supported_protocol_bindings - TransportProtocol enum values now uppercase (JSONRPC, HTTP_JSON) - Client send_message() takes SendMessageRequest proto and yields StreamResponse (use .WhichOneof("payload") to dispatch) - proto Struct metadata: use "in" + subscript instead of .get() - AgentCard construction: use json_format.ParseDict() not **dict - v1 SDK requires Task enqueued before TaskStatusUpdateEvent Files changed: pyproject.toml, 16 source files, 15 test files All 299 a2a unit + integration tests pass (2 skipped for removed A2AFastAPIApplication which has no 1.x equivalent).

Also fix proto Task construction (remove 'kind' field, use Role.ROLE_USER enum). All 301 a2a tests now pass with 0 skipped. --- .../a2a/integration/test_client_server.py | 62 +++++++++---------- 1 file changed, 31 insertions(+), 31 deletions(-) diff --git a/tests/unittests/a2a/integration/test_client_server.py b/tests/unittests/a2a/integration/test_client_server.py index b1ef8eaa00..24386db43a 100644 --- a/tests/unittests/a2a/integration/test_client_server.py +++ b/tests/unittests/a2a/integration/test_client_server.py @@ -18,6 +18,10 @@ from unittest.mock import AsyncMock from a2a.server.request_handlers import DefaultRequestHandler as RequestHandler +from a2a.server.routes import create_agent_card_routes +from a2a.server.routes import create_jsonrpc_routes +from a2a.server.routes import create_rest_routes +from a2a.server.routes.fastapi_routes import add_a2a_routes_to_fastapi from a2a.types import Message as A2AMessage from a2a.types import Part as A2APart from a2a.types import Part @@ -26,6 +30,7 @@ from a2a.types import Task from a2a.types import TaskState from a2a.types import TaskStatus +from fastapi import FastAPI from google.adk.a2a.agent.interceptors.new_integration_extension import _NEW_A2A_ADK_INTEGRATION_EXTENSION from google.adk.a2a.converters.to_adk_event import MOCK_FUNCTION_CALL_FOR_REQUIRED_USER_INPUT from google.adk.a2a.executor.config import A2aAgentExecutorConfig @@ -673,10 +678,6 @@ async def mock_run_async(**kwargs): assert artifacts_by_name["artifact2"].parts[0].text == "artifact content" -@pytest.mark.skip( - reason="Requires A2AFastAPIApplication removed in a2a-sdk v1; " - "needs full rewrite using v1 route builders" -) @pytest.mark.asyncio async def test_user_follow_up_sends_task_id_with_input_required(): """Test that client follow-up sends the same task_id.""" @@ -686,34 +687,35 @@ async def test_user_follow_up_sends_task_id_with_input_required(): mock_task = Task( id=task_id, context_id=context_id, - kind="task", status=TaskStatus( state=TaskState.TASK_STATE_INPUT_REQUIRED, message=A2AMessage( message_id="mocked-message-id-789", - role="user", + role=Role.ROLE_USER, parts=[Part(text="Input required")], ), ), - metadata={_NEW_A2A_ADK_INTEGRATION_EXTENSION: True}, ) + mock_task.metadata[_NEW_A2A_ADK_INTEGRATION_EXTENSION] = True + + completed_task = Task( + id=task_id, + context_id=context_id, + status=TaskStatus(state=TaskState.TASK_STATE_COMPLETED), + ) + completed_task.metadata[_NEW_A2A_ADK_INTEGRATION_EXTENSION] = True mock_handler = AsyncMock(spec=RequestHandler) # First call returns input_required, second call completes - mock_handler.on_message_send.side_effect = [ - mock_task, - Task( - id=task_id, - context_id=context_id, - kind="task", - status=TaskStatus(state=TaskState.TASK_STATE_COMPLETED), - metadata={_NEW_A2A_ADK_INTEGRATION_EXTENSION: True}, - ), - ] + mock_handler.on_message_send.side_effect = [mock_task, completed_task] - app = A2AFastAPIApplication( - agent_card=agent_card, http_handler=mock_handler - ).build() + app = FastAPI() + add_a2a_routes_to_fastapi( + app, + agent_card_routes=create_agent_card_routes(agent_card), + jsonrpc_routes=create_jsonrpc_routes(mock_handler, rpc_url="/"), + rest_routes=create_rest_routes(mock_handler), + ) agent = create_client(app, streaming=False) session_service = InMemorySessionService() @@ -757,25 +759,20 @@ async def test_user_follow_up_sends_task_id_with_input_required(): assert params_2.message.task_id == task_id -@pytest.mark.skip( - reason="Requires A2AFastAPIApplication removed in a2a-sdk v1; " - "needs full rewrite using v1 route builders" -) @pytest.mark.asyncio async def test_user_follow_up_sends_task_id_with_input_required_legacy_impl(): - """Test that client follow-up sends the same task_id.""" + """Test that client follow-up sends the same task_id (no ADK extension metadata).""" task_id = "mocked-task-id-123" context_id = "mocked-context-id-456" mock_task = Task( id=task_id, context_id=context_id, - kind="task", status=TaskStatus( state=TaskState.TASK_STATE_INPUT_REQUIRED, message=A2AMessage( message_id="mocked-message-id-789", - role="user", + role=Role.ROLE_USER, parts=[Part(text="Input required")], ), ), @@ -788,14 +785,17 @@ async def test_user_follow_up_sends_task_id_with_input_required_legacy_impl(): Task( id=task_id, context_id=context_id, - kind="task", status=TaskStatus(state=TaskState.TASK_STATE_COMPLETED), ), ] - app = A2AFastAPIApplication( - agent_card=agent_card, http_handler=mock_handler - ).build() + app = FastAPI() + add_a2a_routes_to_fastapi( + app, + agent_card_routes=create_agent_card_routes(agent_card), + jsonrpc_routes=create_jsonrpc_routes(mock_handler, rpc_url="/"), + rest_routes=create_rest_routes(mock_handler), + ) agent = create_client(app, streaming=False) session_service = InMemorySessionService()
