Wazir Ahmed	5219d4be93	processlist: Prevent crash due to SQLITE_TOOBIG ... - Add new mysql/pgsql variable `processlist_max_query_length`. - Min: 1K - Max: 32M - Default: 2M - Truncate current query based on the configuration before inserting into `stats_*_processlist` tables. - Refactor/fix code related to other processlist configurations. 1. `session_idle_show_processlist` value was not updated in `ProxySQL_Admin.variables`. 2. Pass processlist config as an argument to `MySQL_Threads_Handler::SQL3_Processlist` instead of using thread-local variables. Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	6 months ago

Rahim Kanji	03b63f6857	Fix ParameterStatus capitalization for DateStyle, TimeZone, and IntervalStyle ... These parameters use capitalized names in PostgreSQL for historical reasons. ProxySQL now sends them using canonical capitalization to ensure client compatibility.	7 months 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.	7 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.	7 months ago

Rahim Kanji	7d5fe54230	Refactor: unify result handling for Parse and Describe ... Previously, Parse and Describe each had their own query result handling paths. This duplicated a lot of logic and also failed to handle some cases correctly—for example, Notice messages returned by the server during extended-protocol queries. Keeping these separate paths would be hard to maintain and prone to bugs. The simple-query result handling is already mature, optimized, and covers all the necessary cases. Reusing it for Parse and Describe makes behavior consistent across simple and extended query flows, while also reducing duplicate code.	8 months ago

Javier Jaramago Fernández	d49a96dade	Enforce 'CLIENT_DEPRECATE_EOF' capability match for fast-forward ... - Ensures matching for 'CLIENT_DEPRECATE_EOF' capability when creating or acquiring backend conns for 'fast-forward' sessions. - Since 'CLIENT_DEPRECATE_EOF' capability isn't enforced on backend connections for regular sessions, a mismatch between client and backend capabilities is possible. A verification has been introduced when a session switches to 'fast-forward', in case of capabilities mismatch, an error is logged and client disconnected.	1 year ago

Javier Jaramago Fernández	100630fba5	Second iteration on PostgreSQL monitoring POC ... This commit packs multiple fixes/improvements: - Added READONLY support for PostgreSQL. - Major rework for queries and statements used on monitoring checks: + Checks/Actions rewrote for single instance checks. + Reuse of prepared statements instance of re-preparation. - Fixed missing error handling in connection creation state machine. - Fixed connection rotation in connection pool (now FIFO). - Added support for configurable batching in scheduler thread, via '*_interval_window' variables. These variables allows to define the burstiness of the scheduling within the processing interval. - Added new config variable 'pgsql-monitor_dbname'. Allows to control which 'db' will be target by monitoring connections. - Several fixes for 'poll' timeout computation for worker threads. - Fixed edge cases for current interval detection. - Reduced deviation in scheduling intervals computation. - Refactored and simplified connection event handling. - Improved error messages for monitoring actions. - Replaced several invalid uses of 'mysql_thread___monitor_*' in favor or new 'mysql_thread___monitor_*' variables. - Honor '-M' argument for disabling monitoring support.	1 year ago
