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)	5 months 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)	5 months ago
Rene Cannao	a3f0bade4e	feat: Convert NL2SQL to generic LLM bridge ... - Rename NL2SQL_Converter to LLM_Bridge for generic prompt processing - Update MySQL protocol handler from /* NL2SQL: */ to /* LLM: */ - Remove SQL-specific fields (sql_query, confidence, tables_used) - Add GENAI_OP_LLM operation type to GenAI module - Rename all genai_nl2sql_* variables to genai_llm_* - Update AI_Features_Manager to use LLM_Bridge - Deprecate ai_nl2sql_convert MCP tool with error message - LLM bridge now handles any prompt type via MySQL protocol This enables generic LLM access (summarization, code generation, translation, analysis) while preserving infrastructure for future NL2SQL implementation via Web UI + external agents.	5 months ago
Rene Cannao	3f44229e28	feat: Add MCP AI Tool Handler for NL2SQL with test script ... Phase 5: MCP Tool Implementation for NL2SQL This commit implements the AI Tool Handler for the MCP (Model Context Protocol) server, exposing NL2SQL functionality as an MCP tool. **New Files:** - include/AI_Tool_Handler.h: Header for AI_Tool_Handler class - Provides ai_nl2sql_convert tool via MCP protocol - Wraps NL2SQL_Converter and Anomaly_Detector - Inherits from MCP_Tool_Handler base class - lib/AI_Tool_Handler.cpp: Implementation - Implements ai_nl2sql_convert tool execution - Accepts parameters: natural_language (required), schema, context_tables, max_latency_ms, allow_cache - Returns JSON response with sql_query, confidence, explanation, cached, cache_id - scripts/mcp/test_nl2sql_tools.sh: Test script for NL2SQL MCP tool - Tests ai_nl2sql_convert via JSON-RPC over HTTPS - 10 test cases covering SELECT, WHERE, JOIN, aggregation, etc. - Includes error handling test for empty queries - Supports --verbose, --quiet options **Modified Files:** - include/MCP_Thread.h: Add AI_Tool_Handler forward declaration and pointer - lib/Makefile: Add AI_Tool_Handler.oo to _OBJ_CXX list - lib/ProxySQL_MCP_Server.cpp: Initialize and register AI tool handler - Creates AI_Tool_Handler with GloAI components - Registers /mcp/ai endpoint - Adds cleanup in destructor **MCP Tool Details:** - Endpoint: /mcp/ai - Tool: ai_nl2sql_convert - Parameters: - natural_language (string, required): Natural language query - schema (string, optional): Database schema name - context_tables (string, optional): Comma-separated table list - max_latency_ms (integer, optional): Max acceptable latency - allow_cache (boolean, optional): Check semantic cache (default: true) **Testing:** Run the test script with: ./scripts/mcp/test_nl2sql_tools.sh [--verbose] [--quiet] See scripts/mcp/test_nl2sql_tools.sh --help for usage.
