Rene Cannao	0ff2e38e22	Implement async GenAI module with socketpair-based non-blocking architecture ... - Add GenAI_RequestHeader and GenAI_ResponseHeader protocol structures for socketpair communication - Implement GenAI listener_loop to read requests from epoll and queue to workers - Implement GenAI worker_loop to process requests and send responses via socketpair - Add GenAI_PendingRequest state management to MySQL_Session/Base_Session - Implement MySQL_Session async handlers: genai_send_async(), handle_genai_response(), genai_cleanup_request() - Modify MySQL_Session genai handler to use async path when epoll is available - Initialize GenAI epoll fd in Base_Session::init() This completes the async architecture that was planned but never fully implemented (previously had only placeholder comments). The GenAI module now processes requests asynchronously without blocking MySQL threads.	1 month ago
Javier Jaramago Fernández	4b28bb6ced	Fix heap-after-use between 'PROXYSQL INTERNAL SESSION' and 'SHOW PROCESSLIST' ... Missing query cleanup in 'PROXYSQL INTERNAL SESSION' could lead to invalid memory accesses during 'SHOW PROCESSLIST' sessions scan.	4 months ago
Rahim Kanji	23a764eaac	Preserve implicit transactions with pipeline + FLUSH #5118 ... Previously, each extended-query block was terminated with a SYNC, which caused implicit transactions to commit prematurely. As a result, earlier write operations (INSERT/UPDATE/DELETE) could not be rolled back if a later statement in the same sequence failed. This change switches to libpq pipeline mode and replaces intermediate SYNC messages with FLUSH, ensuring that all client query frames execute as part of the same implicit transaction. A final SYNC is still issued to resynchronize the connection and make it safe for reuse in the pool.	5 months ago
