From 2ba5b35620cadd6bf85ff4c7b98cedfa2efd9575 Mon Sep 17 00:00:00 2001 From: Bartosz Burda Date: Wed, 4 Mar 2026 17:35:13 +0100 Subject: [PATCH 01/13] feat(discovery): add layered MergePipeline with field-group merge Introduce MergePolicy (AUTHORITATIVE/ENRICHMENT/FALLBACK), FieldGroup enums, MergeReport diagnostics, DiscoveryLayer interface and LayerOutput struct. Implement MergePipeline core with single-layer passthrough and multi-layer field-group merge with conflict resolution. --- src/ros2_medkit_gateway/CMakeLists.txt | 6 + .../discovery/discovery_layer.hpp | 64 +++ .../discovery/merge_pipeline.hpp | 82 ++++ .../discovery/merge_types.hpp | 87 ++++ .../src/discovery/merge_pipeline.cpp | 422 ++++++++++++++++++ .../test/test_merge_pipeline.cpp | 321 +++++++++++++ 6 files changed, 982 insertions(+) create mode 100644 src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_layer.hpp create mode 100644 src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/merge_pipeline.hpp create mode 100644 src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/merge_types.hpp create mode 100644 src/ros2_medkit_gateway/src/discovery/merge_pipeline.cpp create mode 100644 src/ros2_medkit_gateway/test/test_merge_pipeline.cpp diff --git a/src/ros2_medkit_gateway/CMakeLists.txt b/src/ros2_medkit_gateway/CMakeLists.txt index 835d05ec..62b932be 100644 --- a/src/ros2_medkit_gateway/CMakeLists.txt +++ b/src/ros2_medkit_gateway/CMakeLists.txt @@ -92,6 +92,7 @@ add_library(gateway_lib STATIC src/discovery/discovery_manager.cpp src/discovery/runtime_discovery.cpp src/discovery/hybrid_discovery.cpp + src/discovery/merge_pipeline.cpp # Discovery models (with .cpp serialization) src/discovery/models/app.cpp src/discovery/models/function.cpp @@ -325,6 +326,10 @@ if(BUILD_TESTING) ament_add_gtest(test_runtime_linker test/test_runtime_linker.cpp) target_link_libraries(test_runtime_linker gateway_lib) + # Add merge pipeline tests + ament_add_gtest(test_merge_pipeline test/test_merge_pipeline.cpp) + target_link_libraries(test_merge_pipeline gateway_lib) + # Add capability builder tests ament_add_gtest(test_capability_builder test/test_capability_builder.cpp) target_link_libraries(test_capability_builder gateway_lib) @@ -488,6 +493,7 @@ if(BUILD_TESTING) test_plugin_manager test_log_manager test_log_handlers + test_merge_pipeline ) foreach(_target ${_test_targets}) target_compile_options(${_target} PRIVATE --coverage -O0 -g) diff --git a/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_layer.hpp b/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_layer.hpp new file mode 100644 index 00000000..22d107eb --- /dev/null +++ b/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_layer.hpp @@ -0,0 +1,64 @@ +// Copyright 2026 bburda +// +// Licensed under the Apache License, Version 2.0 (the "License");

Includes multi-match detection, binding conflict reporting, orphan node warnings, and deterministic namespace matching. Wire MergePipeline into HybridDiscoveryStrategy replacing the ad-hoc merge logic. --- src/ros2_medkit_gateway/design/index.rst | 1 - .../discovery/discovery_manager.hpp | 5 + .../discovery/hybrid_discovery.hpp | 88 ++--- .../discovery/manifest/runtime_linker.hpp | 36 +- .../discovery/merge_pipeline.hpp | 19 ++ .../discovery/runtime_discovery.hpp | 16 +- .../src/discovery/discovery_manager.cpp | 47 ++- .../src/discovery/hybrid_discovery.cpp | 127 ++----- .../src/discovery/manifest/runtime_linker.cpp | 203 +++++++----- .../src/discovery/merge_pipeline.cpp | 35 ++ .../src/discovery/runtime_discovery.cpp | 123 +++---- src/ros2_medkit_gateway/src/gateway_node.cpp | 51 ++- .../test/test_merge_pipeline.cpp | 73 +++++ .../test/test_runtime_linker.cpp | 310 +++++++++++++----- 14 files changed, 650 insertions(+), 484 deletions(-) diff --git a/src/ros2_medkit_gateway/design/index.rst b/src/ros2_medkit_gateway/design/index.rst index ea0ad6ae..7b9886d0 100644 --- a/src/ros2_medkit_gateway/design/index.rst +++ b/src/ros2_medkit_gateway/design/index.rst @@ -55,7 +55,6 @@ The following diagram shows the relationships between the main components of the } class RuntimeDiscoveryStrategy { - + discover_node_components(): vector + discover_synthetic_components(): vector + discover_topic_components(): vector - config_: RuntimeConfig diff --git a/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_manager.hpp b/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_manager.hpp index 0b33f35a..6a76dca1 100644 --- a/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_manager.hpp +++ b/src/ros2_medkit_gateway/include/ros2_medkit_gateway/discovery/discovery_manager.hpp @@ -17,7 +17,9 @@ #include "ros2_medkit_gateway/discovery/discovery_enums.hpp" #include "ros2_medkit_gateway/discovery/discovery_strategy.hpp" #include "ros2_medkit_gateway/discovery/hybrid_discovery.hpp" +#include "ros2_medkit_gateway/discovery/layers/runtime_layer.hpp" #include "ros2_medkit_gateway/discovery/manifest/manifest_manager.hpp" +#include "ros2_medkit_gateway/discovery/merge_types.hpp" #include "ros2_medkit_gateway/discovery/models/app.hpp" #include "ros2_medkit_gateway/discovery/models/area.hpp" #include "ros2_medkit_gateway/discovery/models/common.hpp" @@ -349,6 +351,9 @@ class DiscoveryManager { std::unique_ptr manifest_manager_;

From 8a582005de3b7b3ab2cc95605cc46d98064968f7 Mon Sep 17 00:00:00 2001 From: Bartosz Burda Date: Wed, 4 Mar 2026 18:51:33 +0100 Subject: [PATCH 04/13] feat(discovery): add plugin integration, config, and /health reporting Integrate IntrospectionProviders as pipeline layers with priority ordering and batch registration. Add YAML configuration for merge pipeline gap-fill. Expose MergeReport and LinkingResult in GET /health endpoint. Pass merged entity context (IntrospectionInput) to plugin layers before discover(). Add comprehensive documentation for merge pipeline architecture, policies, gap-fill options, and merge report diagnostics. --- docs/config/discovery-options.rst | 104 +++++ docs/tutorials/manifest-discovery.rst | 73 ++- docs/tutorials/plugin-system.rst | 10 +- src/ros2_medkit_fault_manager/CMakeLists.txt | 2 + src/ros2_medkit_gateway/CMakeLists.txt | 2 + .../config/gateway_params.yaml | 20 + .../design/architecture.puml | 29 +- src/ros2_medkit_gateway/design/index.rst | 74 ++- .../discovery/discovery_layer.hpp | 9 + .../discovery/discovery_manager.hpp | 49 +- .../discovery/hybrid_discovery.hpp | 8 +- .../discovery/layers/plugin_layer.hpp | 6 +- .../discovery/layers/runtime_layer.hpp | 6 + .../discovery/merge_pipeline.hpp | 10 +- .../discovery/merge_types.hpp | 36 +- .../discovery/runtime_discovery.hpp | 4 +- .../plugins/plugin_manager.hpp | 6 + .../providers/introspection_provider.hpp | 5 +- .../src/discovery/discovery_manager.cpp | 40 +- .../src/discovery/hybrid_discovery.cpp | 14 +- .../src/discovery/layers/plugin_layer.cpp | 43 +- .../src/discovery/layers/runtime_layer.cpp | 12 +- .../src/discovery/merge_pipeline.cpp | 77 +++- .../src/discovery/runtime_discovery.cpp | 6 +- src/ros2_medkit_gateway/src/gateway_node.cpp | 33 ++ .../src/http/handlers/health_handlers.cpp | 30 +- .../src/plugins/plugin_manager.cpp | 14 + .../test/test_auth_manager.cpp | 4 +- .../test/test_health_handlers.cpp | 8 + .../test/test_merge_pipeline.cpp | 429 +++++++++++++++++- .../test/test_runtime_linker.cpp | 29 ++ .../test_scenario_discovery_hybrid.test.py | 11 + 32 files changed, 1096 insertions(+), 107 deletions(-) diff --git a/docs/config/discovery-options.rst b/docs/config/discovery-options.rst index 4d5a307f..e4261216 100644 --- a/docs/config/discovery-options.rst +++ b/docs/config/discovery-options.rst @@ -87,6 +87,98 @@ The ``min_topics_for_component`` parameter (default: 1) sets the minimum number of topics required before creating a component.
