René Cannaò	37ce0525bb	Fix connection pool extraction: separate header, proper unit tests ... Fixes the Copilot-generated PR #5500 production code and test file: Production fixes: - Create standalone ConnectionPoolDecision.h header with the struct and function declarations (no circular dependency issues) - Include ConnectionPoolDecision.h in MySrvConnList.cpp and PgSQL_HostGroups_Manager.cpp to resolve compilation errors - Replace inline declarations in Base_HostGroups_Manager.h with #include "ConnectionPoolDecision.h" Test fixes: - Remove misplaced test from test/tap/tests/ (tested reimplemented copies of functions instead of the real code) - Add proper unit test at test/tap/tests/unit/connection_pool_unit-t.cpp using the test harness (test_globals.h, test_init.h) - 22 test cases covering eviction, throttling, pool state decisions, warming, and edge cases - Register in unit test Makefile	3 weeks ago

Wazir Ahmed	fc12e9a6ab	Add protocol label to connpool Prometheus metrics ... MySQL and PgSQL share the same metric family names for connection pool metrics. Since they have independent hostgroup ID namespaces, add a protocol label to distinguish metrics from each module. **Affected metrics:** - `proxysql_connpool_conns` - `proxysql_connpool_conns_total` - `proxysql_connpool_conns_queries_total` - `proxysql_connpool_conns_latency_us` - `proxysql_connpool_conns_status` - `proxysql_connpool_data_bytes_total` Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	1 month ago

Rene Cannao	ee85b11ad5	refactor: migrate prepare_v2 SIMPLE case in PgSQL_HostGroups_Manager.cpp ... Migrated 1 function with 2 prepare_v2 calls to RAII-based pattern in: - generate_pgsql_hostgroup_attributes_table(): 2 statements (statement1, statement2) The RAII pattern ensures automatic cleanup and eliminates manual (*proxy_sqlite3_finalize) calls.	2 months ago
Rene Cannao	854ab4fbb6	refactor: migrate generate_pgsql_hostgroup_attributes_table() to RAII prepare_v2 ... - Changed from raw pointer to smart pointer-based prepare_v2 - Fixes existing memory leak where statement was never finalized - RAII ensures automatic cleanup when function exits	2 months ago

Rene Cannao	e3026cbc6f	Fix wrong index in connection cleanup loops (MySQL and PgSQL) ... This commit fixes a bug where connection cleanup loops were removing the wrong connection from the pool. The loops checked each connection by index (i), but when an expired connection was found, they removed index 0 instead of index i. This caused: - Fresh connections at index 0 to be incorrectly deleted - Expired connections to remain in the pool Fixed files: - lib/Base_HostGroups_Manager.cpp:2603 (MySQL) - lib/MySQL_HostGroups_Manager.cpp:2939 (MySQL) - lib/PgSQL_HostGroups_Manager.cpp:2782 (PgSQL) The fix changes `remove(0)` to `remove(i)` to remove the correct connection. Related: #5094 (fixes similar issue in drop_all_idle_connections)	2 months ago
Rene Cannao	4aedacd83b	[skip-ci] Remove deprecated read_only_action implementations from MySQL and PgSQL HostGroups managers ... The old read_only_action() implementations were marked for deletion after 2025-07-14. These were replaced with new implementation that doesn't depend on the admin table. This change removes the deprecated code paths to clean up the codebase.	3 months ago

Rahim Kanji	ff50bb4ec1	Ensure PgSQL_Errors_statsvdestructor is invoked on delete #5112 ... Previously, deleting `PgSQL_Errors_stats` instances in TUs with only a forward declaration caused the destructor to be skipped, leaking member allocations. The fix ensures the full class definition is visible at delete sites.	7 months 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
