Rene Cannao	c2f678a9de	feat: implement release tiers and feature guards for v3.0, v3.1, and v4.0 This commit introduces a structured release tier system controlled by environment variables, allowing three distinct ProxySQL versions to be built from the same codebase while maintaining a clear upgrade path. Key Changes: - Tier 1 (v3.0.x Stable): Default build including bug fixes and core enhancements. - Tier 2 (v3.1.x Innovative): Enabled via PROXYSQL31=1. Adds FFTO and TSDB. - Tier 3 (v4.0.x AI/MCP): Enabled via PROXYSQLGENAI=1. Adds the AI stack. Implementation Details: - Makefile: Implemented dynamic versioning logic that increments the minor version for v3.1 and the major version for v4.0. Added tier documentation. - Feature Guards: Introduced PROXYSQLFFTO and PROXYSQLTSDB guards across ProxySQL_Admin, ProxySQL_Statistics, REST API, and HTTP server. - FFTO: Guarded Fast Forward Traffic Observer in MySQL and PgSQL sessions, including thread-local variables and configuration parameters. - TSDB: Guarded the entire Time Series Database subsystem, including SQLite table definitions, background loops, and REST API endpoints. - Build Fixes: * Fixed 'proxy_debug_func' linkage by adding extern "C" and moving the definition outside of DEBUG guards to ensure non-debug builds link correctly. * Corrected misplaced/nested DEBUG and PROXYSQLFFTO guards. * Verified build stability for all tiers (unset, PROXYSQL31=1, PROXYSQLGENAI=1).	1 month ago

Rene Cannao	1c25787b88	Introduce {mysql,pgsql}-query_processor_first_comment_parsing variable (#5384 ) This universal fix allows controlling when the first comment of a query is processed relative to the query rules. By setting this variable to 1, ProxySQL-specific annotations (like GTID) can be parsed immediately, allowing subsequent query rules to strip them from the query string. This prevents prepared statement cache bloat and improves backend statement reuse when annotations with unique literals are used.	2 months ago

Rene Cannao	366164ab26	Fix #5272 : Add mysql-select_version_forwarding variable for SELECT VERSION() Since ProxySQL 3.0.4, SELECT VERSION() queries were intercepted and returned ProxySQL's mysql-server_version variable instead of proxying to backends. This broke SQLAlchemy for MariaDB which expects "MariaDB" in the version string. This commit adds a new variable `mysql-select_version_forwarding` with 4 modes: - 0 = never: Always return ProxySQL's version (3.0.4+ behavior) - 1 = always: Always proxy to backend (3.0.3 behavior) - 2 = smart (fallback to 0): Try backend connection, else ProxySQL version - 3 = smart (fallback to 1): Try backend connection, else proxy (default) The implementation includes: - New global variable mysql_thread___select_version_forwarding - New function get_backend_version_for_hostgroup() to peek at backend connection versions without removing them from the pool - Modified SELECT VERSION() handler to support all 4 modes - ProxySQL backend detection to avoid recursion Mode 3 (default) ensures SQLAlchemy always gets the real MariaDB version string while maintaining fast response when connections are available.	3 months ago

Rene Cannao	44aa606caa	Implement fast forward grace close feature to prevent data loss Problem: In fast forward mode, ProxySQL forwards packets directly from client to backend without buffering them. If the backend connection closes unexpectedly (e.g., due to server crash, network failure, or other issues), ProxySQL immediately closes the client session. This can result in data loss because the client may have sent additional data that hasn't been fully transmitted yet, as ProxySQL does not wait for the output buffers to drain. Solution: Implement a configurable grace period for session closure in fast forward mode. When the backend closes unexpectedly, instead of closing the session immediately, ProxySQL waits for a configurable timeout (fast_forward_grace_close_ms, default 5000ms) to allow any pending client output data to be sent. During this grace period: - If the client output buffers become empty, the session closes gracefully. - If the timeout expires, the session closes anyway to prevent indefinite hanging. Changes: - Added global variable mysql_thread___fast_forward_grace_close_ms (0-3600000ms) - Added session flags: backend_closed_in_fast_forward, fast_forward_grace_start_time - Added data stream flag: defer_close_due_to_fast_forward - Modified MySQL_Data_Stream::read_from_net() to detect backend EOF and initiate grace close if client buffers are not empty - Modified MySQL_Session::handler() FAST_FORWARD case to implement grace close logic with timeout and buffer checks - Added extensive inline documentation explaining the feature and its mechanics This prevents data loss in fast forward scenarios while maintaining bounded session lifetime.	5 months ago
Lisandro Pin	6cb522283d	Implement a ignore_min_gtid_annotation global variable for ProxySQL When true, all `min_gtid` query annotations are ignored; see https://proxysql.com/documentation/query-annotations/ for details. This is useful on ProxySQL setups with multiple layers, where some layers mandate GTID-based routing while others don't.	5 months ago
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	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.	6 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.	7 months ago
