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)	3 weeks 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.	1 month ago
Rene Cannao	3fe8a48f70	Fix genai variable handling and add API key masking ... - Add has_variable() method to GenAI_Threads_Handler for variable validation - Add genai- prefix check in is_valid_global_variable() - Auto-initialize NL2SQL converter when genai-nl2sql_enabled is set to true at runtime - Make init_nl2sql() public to allow runtime initialization - Mask API keys in logs (show only first 2 chars, rest as 'x')	1 month ago
Rene Cannao	527bfed297	fix: Migrate AI variables to GenAI module for proper architecture ... This commit fixes a serious design flaw where AI configuration variables were not integrated with the ProxySQL admin interface. All ai_* variables have been migrated to the GenAI module as genai-* variables. Changes: - Added 21 new genai_* variables to GenAI_Thread.h structure - Implemented get/set functions for all new variables in GenAI_Thread.cpp - Removed internal variables struct from AI_Features_Manager - AI_Features_Manager now reads from GloGATH instead of internal state - Updated documentation to reference genai-* variables - Fixed debug.cpp assertion for PROXY_DEBUG_NL2SQL and PROXY_DEBUG_ANOMALY Variable mapping: - ai_nl2sql_enabled → genai-nl2sql_enabled - ai_anomaly_detection_enabled → genai-anomaly_enabled - ai_features_enabled → genai-enabled - All other ai_* variables follow the same pattern The flush functions automatically handle all variables in the genai_thread_variables_names array, so database persistence works correctly without additional changes.

Rene Cannao	ae4200dbc0	Enhance AI features with improved validation, memory safety, error handling, and performance monitoring ... - Rename validate_provider_name to validate_provider_format for clarity - Add null checks and error handling for all strdup() operations - Enhance error messages with more context and HTTP status codes - Implement performance monitoring with timing metrics for LLM calls and cache operations - Add comprehensive test coverage for edge cases, retry scenarios, and performance - Extend status variables to track performance metrics - Update MySQL session to report timing information to AI manager	1 month ago
Rene Cannao	897d306d2d	Refactor: Simplify NL2SQL to use only generic providers ... Remove Ollama-specific provider code and use only generic OpenAI-compatible and Anthropic-compatible providers. Ollama is now used via its OpenAI-compatible endpoint at /v1/chat/completions. Changes: - Remove LOCAL_OLLAMA from ModelProvider enum - Remove ai_nl2sql_ollama_model and ai_nl2sql_ollama_url variables - Remove call_ollama() function from LLM_Clients.cpp - Update default configuration to use OpenAI provider with Ollama URL - Update all documentation to reflect generic-only approach Configuration: - ai_nl2sql_provider: 'openai' or 'anthropic' (default: 'openai') - ai_nl2sql_provider_url: endpoint URL (default: Ollama OpenAI-compatible) - ai_nl2sql_provider_model: model name - ai_nl2sql_provider_key: API key (optional for local endpoints) This simplifies the codebase by removing a separate code path for Ollama and aligns with the goal of avoiding provider-specific variables.	1 month ago
Rene Cannao	4f45c25945	docs: Add comprehensive doxygen comments to NL2SQL headers and LLM_Clients ... - Add file-level doxygen documentation with @file, @brief, @date, @version - Add detailed class and method documentation with @param, @return, @note, @see - Document data structures (NL2SQLRequest, NL2SQLResult, ModelProvider) - Add section comments and inline documentation for implementation files - Document all three LLM provider APIs (Ollama, OpenAI, Anthropic)	1 month ago
Rene Cannao	d9346fe64d	feat: Add AI features manager foundation ... - Add AI_Features_Manager coordinator class - Add AI_Vector_Storage interface (stub) - Add Anomaly_Detector class (stub for Phase 3) - Update includes and main initialization	1 month ago
