From 64ee819c126b1709cf51fc89a75b197111f6df3c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20F=C4=85ferek?= Date: Sun, 14 Dec 2025 14:08:08 +0100 Subject: [PATCH 1/3] feat(#77): add REST API endpoints for fault management Gateway REST API Endpoints for fault management. Adds FaultManager class that interfaces with ros2_medkit_fault_manager services and exposes fault operations via REST API. New REST endpoints: - GET /api/v1/components/{id}/faults - list faults (REQ_INTEROP_012) - GET /api/v1/components/{id}/faults/{code} - get fault (REQ_INTEROP_013) - POST /api/v1/components/{id}/faults - report fault - DELETE /api/v1/components/{id}/faults/{code} - clear fault (REQ_INTEROP_015) Changes: - Add FaultManager class with service clients for fault_manager - Integrate FaultManager into GatewayNode - Add fault endpoint handlers to RESTServer - Add 'faults' capability to root endpoint - Add integration tests (test_55-63) with fault_manager_node - Update Postman collection and README with Faults folder --- postman/README.md | 15 + ...os2-medkit-gateway.postman_collection.json | 114 +++++++ src/ros2_medkit_gateway/CMakeLists.txt | 3 + .../ros2_medkit_gateway/fault_manager.hpp | 100 ++++++ .../ros2_medkit_gateway/gateway_node.hpp | 8 + .../ros2_medkit_gateway/rest_server.hpp | 5 + src/ros2_medkit_gateway/package.xml | 2 + src/ros2_medkit_gateway/src/fault_manager.cpp | 234 ++++++++++++++ src/ros2_medkit_gateway/src/gateway_node.cpp | 5 + src/ros2_medkit_gateway/src/rest_server.cpp | 296 +++++++++++++++++- .../test/test_integration.test.py | 147 ++++++++- 11 files changed, 914 insertions(+), 15 deletions(-) create mode 100644 src/ros2_medkit_gateway/include/ros2_medkit_gateway/fault_manager.hpp create mode 100644 src/ros2_medkit_gateway/src/fault_manager.cpp diff --git a/postman/README.md b/postman/README.md index f2f98c7..d871b6f 100644 --- a/postman/README.md +++ b/postman/README.md @@ -35,6 +35,11 @@ All endpoints are prefixed with `/api/v1` for API versioning. - ✅ DELETE `/api/v1/components/{component_id}/configurations/{param}` - Reset parameter to default value - ✅ DELETE `/api/v1/components/{component_id}/configurations` - Reset all parameters to default values +### Faults Endpoints (Fault Management) +- ✅ GET `/api/v1/components/{component_id}/faults` - List all faults for a component +- ✅ GET `/api/v1/components/{component_id}/faults/{fault_code}` - Get specific fault details +- ✅ DELETE `/api/v1/components/{component_id}/faults/{fault_code}` - Clear a fault + ## Quick Start ### 1.

Fix fault filtering to use prefix matching for namespace hierarchy (allows querying by namespace e.g. /perception/lidar matches /perception/lidar/lidar_sensor) - Add LIDAR Fault Workflow folder to Postman collection with 8-step example demonstrating complete fault management lifecycle -
