Rene Cannao	253591d262	Add experimental GenAI EMBED: query support for MySQL ... This commit adds experimental support for generating embeddings directly from MySQL queries using a special EMBED: syntax. Changes: - Add MYDS_INTERNAL_GENAI to MySQL_DS_type enum for GenAI connections - Add handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY___genai_embedding() - Implement EMBED: query detection and JSON parsing for document arrays - Build CSV resultset with embeddings (1 row per document, 1 column) - Add myconn NULL check in MySQL_Thread for INTERNAL_GENAI type - Add "debug_genai" name to debug module array - Remove HAVE_LIBCURL checks (libcurl is always statically linked) - Use static curl header: "curl/curl.h" instead of <curl/curl.h> - Remove curl_global_cleanup() from GenAI module (should only be in main()) Query format: EMBED: ["doc1", "doc2", ...] Result format: 1 row per document, 1 column with CSV embeddings Error handling uses MySQL ERR_Packet instead of resultsets.	3 months ago
Rene Cannao	1da9e384d2	Add poll() fallback for GenAI module when epoll is not available ... This change adds compile-time detection and fallback to poll() on systems that don't support epoll(), improving portability across different platforms. Header changes (include/GenAI_Thread.h): - Make sys/epoll.h include conditional on #ifdef epoll_create1 Implementation changes (lib/GenAI_Thread.cpp): - Add poll.h include for poll() support - Add EPOLL_CREATE compatibility macro (epoll_create1 or epoll_create) - Add #include <poll.h> for poll() support - Update init() to use pipe() for wakeup when epoll is not available - Update register_client() to skip epoll_ctl when epoll is not available - Update unregister_client() to skip epoll_ctl when epoll is not available - Update listener_loop() to use poll() when epoll is not available The compile-time detection works by checking if epoll_create1 is defined (Linux-specific glibc function since 2.9). On systems without epoll, the code falls back to using poll() with a pipe for wakeup signaling.	3 months ago
Rene Cannao	960704066d	Implement real GenAI module with embedding and rerank support ... Header changes (include/GenAI_Thread.h): - Add GenAI_EmbeddingResult, GenAI_RerankResult, GenAI_RerankResultArray structs - Add GenAI_Document, GenAI_Request structures for internal queue - Add 5 configuration variables: genai_threads, genai_embedding_uri, genai_rerank_uri, genai_embedding_timeout_ms, genai_rerank_timeout_ms - Add status variables: threads_initialized, active_requests, completed_requests, failed_requests - Add public API methods: embed_documents(), rerank_documents() - Add client management: register_client(), unregister_client() - Add threading components: worker threads, listener thread, epoll Implementation changes (lib/GenAI_Thread.cpp): - Implement move constructors/destructors for result structures - Initialize default values for variables (threads=4, embedding port 8013, rerank port 8012, timeout 30s) - Implement get_variable/set_variable with validation for all 5 variables - Implement call_llama_batch_embedding() using libcurl - Implement call_llama_rerank() using libcurl - Implement embed_documents() public API (single or batch) - Implement rerank_documents() public API with top_n parameter - Implement register_client() for socket pair integration - Implement listener_loop() and worker_loop() for async processing - Add proper error handling and status tracking Debug integration (include/proxysql_structs.h): - Add PROXY_DEBUG_GENAI to debug_module enum	3 months ago
Rene Cannao	c476f56f97	Add initial GenAI module placeholder ... Implement a new GenAI module for ProxySQL with basic infrastructure: - GenAI_Threads_Handler class for managing GenAI module configuration - Support for genai- prefixed variables in global_variables table - Dummy variables: genai-var1 (string) and genai-var2 (integer) - Config file support via genai_variables section - Flush functions for runtime_to_database and database_to_runtime - Module lifecycle: initialization at startup, graceful shutdown - LOAD/SAVE GENAI VARIABLES admin command infrastructure Core functionality verified: - Config file loading works - Variables persist in global_variables table - Disk save/load via SQL works - Module initializes and shuts down properly Related files: - include/GenAI_Thread.h: New GenAI thread handler class - lib/GenAI_Thread.cpp: Implementation with dummy variables - lib/Admin_Handler.cpp: Added GENAI command vectors and handlers - lib/Admin_FlushVariables.cpp: Added genai flush functions - lib/ProxySQL_Admin.cpp: Added init_genai_variables() and load_save_disk_commands entry - include/proxysql_admin.h: Added function declarations - lib/Makefile: Added GenAI_Thread.oo to build - src/main.cpp: Added module initialization and cleanup - src/proxysql.cfg: Added genai_variables configuration section	3 months ago
