Rene Cannao	b965fc6df4	Fix PROXYSQLGENAI build - resolve circular includes and missing headers ... This commit fixes compilation errors when building with PROXYSQLGENAI=1: Header file fixes: - Add missing #endif /* PROXYSQLGENAI */ before header guards in multiple headers - Remove #include cpp.h from GenAI headers to avoid circular dependencies Source file fixes: - Add #include proxysql.h to GenAI .cpp files that were missing it - Add #include Static_Harvester.h to Query_Tool_Handler.cpp for forward decl Build system fixes: - Remove vec.o from libproxysql.a (it's linked separately in src/Makefile) - Prevents duplicate symbol errors during linking Test files: - Rename MCP test files with .sh suffix to prevent make clean deletion Both build modes now work: - make build_lib_debug (without GenAI) - PROXYSQLGENAI=1 make build_lib_debug (with GenAI)	1 month ago
Rene Cannao	48bc7dd7bf	Merge v4.0 GenAI features into v3.0 with conditional compilation ... This commit merges the experimental v4.0 GenAI/MCP features into the stable v3.0 branch using conditional compilation. All v4.0 features are disabled by default and only enabled when PROXYSQLGENAI=1 is set at compile time. Changes: Build System: - Modified main Makefile to pass PROXYSQLGENAI flag to sub-makefiles - Modified deps/Makefile to conditionally build sqlite-vec and sqlite-rembed - Modified lib/Makefile to add PSQLGA flag and include GenAI object files - Modified src/Makefile to add PSQLGA flag and conditional linking Headers (wrapped with #ifdef PROXYSQLGENAI): - All 20 new GenAI header files in include/ - Modified cpp.h, proxysql_glovars.hpp, proxysql_admin.h - Modified ProxySQL_Admin_Tables_Definitions.h for GenAI/MCP tables Source Files: - All 22 new GenAI source files in lib/ wrapped with #ifdef PROXYSQLGENAI - Modified src/main.cpp for conditional global variables and init/shutdown - Modified Admin_Handler.cpp for conditional command handlers - Modified Admin_Bootstrap.cpp for conditional table registration - Modified Admin_FlushVariables.cpp for conditional variable flushing - Modified ProxySQL_Admin.cpp for conditional admin methods - Modified ProxySQL_Admin_Stats.cpp for conditional MCP stats functions - Modified proxy_sqlite3_symbols.cpp to always compile (needed by core) - Modified MySQL_Session.cpp for conditional GenAI function calls Test Files: - Renamed test_mcp_query_rules-t to test_mcp_query_rules-t.sh - Renamed test_mcp_rag_metrics-t to test_mcp_rag_metrics-t.sh - Modified anomaly_detection-t.cpp for conditional test execution Usage: # Build without GenAI (v3.0 mode - default) make clean && make build_deps -j$(nproc) && make build_lib -j$(nproc) && make build_src -j$(nproc) # Build with GenAI (v4.0 mode) make clean && PROXYSQLGENAI=1 make build_deps -j$(nproc) && PROXYSQLGENAI=1 make build_lib -j$(nproc) && PROXYSQLGENAI=1 make build_src -j$(nproc)	1 month ago
Rene Cannao	c86a048d9c	Implement MCP multi-endpoint architecture with dedicated tool handlers ... This commit implements Option 1 (Multiple Tool Handlers) for the MCP module, where each of the 5 endpoints has its own dedicated tool handler with specific tools. ## Architecture Changes - Created MCP_Tool_Handler base class interface for all tool handlers - Each endpoint now has its own dedicated tool handler: - /mcp/config → Config_Tool_Handler (configuration management) - /mcp/query → Query_Tool_Handler (database exploration) - /mcp/admin → Admin_Tool_Handler (administrative operations) - /mcp/cache → Cache_Tool_Handler (cache management) - /mcp/observe → Observe_Tool_Handler (monitoring & metrics) ## New Files Base Interface: - include/MCP_Tool_Handler.h - Base class for all tool handlers Tool Handlers: - include/Config_Tool_Handler.h, lib/Config_Tool_Handler.cpp - include/Query_Tool_Handler.h, lib/Query_Tool_Handler.cpp - include/Admin_Tool_Handler.h, lib/Admin_Tool_Handler.cpp - include/Cache_Tool_Handler.h, lib/Cache_Tool_Handler.cpp - include/Observe_Tool_Handler.h, lib/Observe_Tool_Handler.cpp Documentation: - doc/MCP/Architecture.md - Comprehensive architecture documentation ## Modified Files - include/MCP_Thread.h, lib/MCP_Thread.cpp - Added 5 tool handler pointers - include/MCP_Endpoint.h, lib/MCP_Endpoint.cpp - Use tool_handler base class - lib/ProxySQL_MCP_Server.cpp - Create and pass handlers to endpoints - lib/Makefile - Added new source files ## Implementation Status - Config_Tool_Handler: Functional (get_config, set_config, list_variables, get_status) - Query_Tool_Handler: Functional (wraps MySQL_Tool_Handler, all 18 tools) - Admin_Tool_Handler: Stub implementations (TODO: implement) - Cache_Tool_Handler: Stub implementations (TODO: implement) - Observe_Tool_Handler: Stub implementations (TODO: implement) See GitHub Issue #8 for detailed TODO list.
