Rene Cannao	4e39297ef9	Fix more Valgrind uninitialized value errors 1. Base_Thread.cpp: Initialize member variables in constructor - curtime, last_move_to_idle_thread_time, epoll_thread, shutdown, mysql_sessions were not initialized, causing uninitialized value use in ProcessAllMyDS_BeforePoll and ProcessAllMyDS_AfterPoll. 2. MySQL_Logger.cpp: Initialize query_ptr, query_len, and buf in MySQL_Event constructor. These fields were used without initialization, causing Valgrind errors in JSON serialization and other operations.	1 week ago
René Cannaò	fcaa904135	fix: crash on macOS/FreeBSD when running PostgreSQL queries Fix NULL pointer dereference in CopyCmdMatcher that caused ProxySQL to crash immediately when running any PostgreSQL query on macOS and FreeBSD systems. Root cause: copy_cmd_matcher was guarded by #ifdef IDLE_THREADS, but IDLE_THREADS is explicitly disabled on macOS (__APPLE__) and FreeBSD in proxy_defines.h. This caused the pointer to be NULL when accessed. The fix removes #ifdef IDLE_THREADS guards from copy_cmd_matcher since COPY command detection is a fundamental PostgreSQL feature for fast- forward mode and has no dependency on idle threads. Affected systems: macOS, FreeBSD (where IDLE_THREADS is disabled) Fixes: #5359	2 weeks ago

Rahim Kanji	4d91452fc5	Implement backend query cancellation for PostgreSQL #5136 Add support for PostgreSQL query cancellation and backend termination features to allow clients to cancel long-running queries and terminate connections through the standard PostgreSQL protocol. Features implemented: - Intercept pg_backend_pid() queries and return ProxySQL session thread ID - Intercept pg_terminate_backend() to terminate client connections asynchronously - Intercept pg_cancel_backend() to cancel queries on backend connections - Support Cancel Request protocol via separate connection with PID and secret key validation - Return BackendKeyData message on successful authentication with session thread ID and unique cancel secret key This enables clients to use standard PostgreSQL cancellation mechanisms (pg_cancel_backend, pg_terminate_backend, and Cancel Request protocol) while ProxySQL maintains proper session isolation and maps client requests to appropriate backend connections.	5 months ago

Rahim Kanji	1bcd09044b	Refactor Connection Reset Handling * Introduced startup parameters in PgSQL_Connection (removed default session parameters from PgSQL_Session) * Startup parameters are populated during both frontend and backend connection creation * Parameters provided via connection options are set as startup parameters * Backend connection parameter handling updated: only critical variables are now set via connection options to prevent interference with DISCARD ALL during connection reset; remaining parameters will be applied using individual SET commands	7 months ago
Rahim Kanji	24fecc1f6e	Add PostgreSQL extended query (prepared statement) support in ProxySQL This commit lays the groundwork for handling PostgreSQL’s extended query protocol (prepared statements) by introducing parsing, it's caching and execution framework stubs. - Implement Parse handling - Implement caching of parse (reuse) - Introduce Execute framework stub for future binding and execution logic.	8 months ago

Rahim Kanji	720441af20	Refactored and Optimized Query Cache with PgSQL Support * Added Query Cache Support for PgSQL: * Introduced new variables for PgSQL Query Cache management: * pgsql-query_cache_size_MB * pgsql-query_cache_soft_ttl_pct * pgsql-query_cache_stores_empty_result * pgsql-query_cache_handle_warnings (not yet utilized) * Overwriting Transaction Status: * Sending current transaction state to the client when a result is returned from the query cache. * This currently does not differentiate between normal and error transaction states—both are treated as active transaction states. * Cache Lifetime Management: Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries, ensuring proper memory deallocation and reducing complexity. * Unified Purging Logic: Refactored the query cache purging logic to use a single thread for both MySQL and PgSQL cache entries. * Code Cleanup: Removed unnecessary methods and data members to streamline the codebase and improve maintainability. * Performance Optimization: Improved memory management, reducing memory footprint and enhancing performance.	1 year ago
