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	51fd51e3f5	fix: Add missing GenAI_Thread.h include and fix variables reference ... Added missing #include for GenAI_Thread.h in AI_Features_Manager.cpp to resolve the compilation error in debug mode. Also fixed the remaining reference to variables.ai_features_enabled which should now use GloGATH->variables.genai_enabled. This fixes the "make debug" build failure.	5 months 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	2888ee3f45	Fix gemini-code-assist recommendations and implement comprehensive anomaly detection tests ... - Fix retry logic to use is_retryable_error function for proper HTTP error handling - Add exception handling to get_json_int function with try-catch around std::stoi - Improve validate_numeric_range to use strtol instead of atoi for better error reporting - Fix Chinese characters in documentation (non-zero -> non-zero) - Replace placeholder tests with actual comprehensive tests for anomaly detection functionality - Create new standalone unit test anomaly_detector_unit-t.cpp with 29 tests covering: * SQL injection pattern detection (12 tests) * Query normalization (8 tests) * Risk scoring calculations (5 tests) * Configuration validation (4 tests) - All tests pass successfully, providing meaningful validation of core anomaly detection logic Thanks to gemini-code-assist for the thorough code review and recommendations.	5 months ago
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	5 months ago
Rene Cannao	49092e9c8d	test: Add unit tests for AI configuration validation ... This commit adds comprehensive unit tests for the AI configuration validation functions used in AI_Features_Manager. Changes: - Add test/tap/tests/ai_validation-t.cpp with 61 unit tests - Test URL format validation (validate_url_format) - Test API key format validation (validate_api_key_format) - Test numeric range validation (validate_numeric_range) - Test provider name validation (validate_provider_name) - Test edge cases and boundary conditions The test file is self-contained with its own copies of the validation functions to avoid complex linking dependencies on libproxysql. Test Categories: - URL validation: 15 tests (http://, https:// protocols) - API key validation: 14 tests (OpenAI, Anthropic formats) - Numeric range: 13 tests (min/max boundaries) - Provider name: 8 tests (openai, anthropic) - Edge cases: 11 tests (NULL handling, long values) All 61 tests pass successfully. Part of: Phase 4 of NL2SQL improvement plan	5 months ago
Rene Cannao	40b2608c2d	feat: Add configuration validation to AI_Features_Manager ... Add comprehensive validation for AI features configuration variables to prevent invalid states and improve error messages. Changes: - Add validate_url_format(): Checks for http:// or https:// prefix and host part - Add validate_api_key_format(): Validates API key format, checks for whitespace, minimum length, and incomplete key patterns (sk- with <20 chars, sk-ant- with <25 chars) - Add validate_numeric_range(): Validates numeric values are within min/max range - Add validate_provider_name(): Ensures provider is 'openai' or 'anthropic' - Update set_variable() to call validation functions before setting values Validated variables: - ai_nl2sql_provider: Must be 'openai' or 'anthropic' - ai_nl2sql_provider_url: Must have http:// or https:// prefix - ai_nl2sql_provider_key: No whitespace, minimum 10 chars - ai_nl2sql_cache_similarity_threshold: Range [0, 100] - ai_nl2sql_timeout_ms: Range [1000, 300000] (1 second to 5 minutes) - ai_nl2sql_max_cloud_requests_per_hour: Range [1, 10000] - ai_anomaly_similarity_threshold: Range [0, 100] - ai_anomaly_risk_threshold: Range [0, 100] - ai_anomaly_rate_limit: Range [1, 10000] - ai_vector_dimension: Range [128, 4096] This prevents misconfigurations and provides clear error messages to users when invalid values are provided. Fixes compilation issue by moving validation helper functions before set_variable() to resolve forward declaration errors.	5 months 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.	5 months ago
