Rahim Kanji	a89291c9a9	Added query logging support for PostgreSQL	7 months ago
Rahim Kanji	a7df0d3b3c	Fixed clang compilation	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

Wazir Ahmed	0a336de048	Add validation for `LOAD * FROM CONFIG` ... - Add validation methods for `mysql_users`, `pgsql_users`, `mysql_servers`, `pgsql_servers` and `proxysql_servers` - Check for duplicates and mandatory fields - Return descriptive error messages to clients when validation fails Signed-off-by: Wazir Ahmed <wazir@proxysql.com> Co-authored-by: takaidohigasi <takaidohigasi@gmail.com>	8 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.	8 months ago
Rahim Kanji	205f970ffa	Append NoData for DESCRIBE(Portal) on SET/RESET/DISCARD/DEALLOCATE	8 months ago
Rahim Kanji	031d362aab	Add STMT prefix to ASYC DESCRIBE status	8 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

Rahim Kanji	9a5fa148c8	Inject implicit Sync if simple query arrives before extended query cycle is completed ... When a simple query arrives while extended query messages are pending, we now: - inject an implicit Sync, - process all extended query messages, - then execute the simple query, - and send ReadyForQuery only after the simple query completes.	8 months ago
Rahim Kanji	be2ae45950	Merge branch 'v3.0' into 'v3.0_extended_query_protocol_phase_2'	8 months ago
Rahim Kanji	abd19113c0	Fix RequestEnd: avoid updating internal state when query failed on backend ... RequestEnd was applying state changes (session variable restore, rollback-to-savepoint, multiplexing toggle for temp tables/sequences) even when the query failed to execute on the backend connection. This caused internal state to diverge from the actual backend state. Fix: - Add success/failure flag to RequestEnd calls. - Restrict state-changing logic to Simple Query and Prepared Execute. - Ensure logic only runs when the query executed successfully on backend. This keeps internal state aligned with the backend connection state.	8 months ago
Rahim Kanji	96c989a854	* Replaced virtual RequestEnd method with CRTP (static polymorphism) ... * Removed multi_pkt from PgSQL_session	8 months ago

Rahim Kanji	7a1852fb92	Skip Describe Portal results unless client explicitly requests it ... PQsendQueryPrepared always emits Bind -> Describe Portal -> Execute, which led to RowDescription being included in the result set even when the client never sent a Describe message. This caused clients to receive row descriptions they did not request. Changes: - Skip including RowDescription when the client did not send Describe. - If the client explicitly sent Describe followed by Execute, continue to skip redundant execution of Describe but include RowDescription once. This ensures RowDescription is only sent when requested, aligning behavior with protocol expectations.	8 months ago
Rahim Kanji	8a3bab5002	Ensure consistent handling of NoData packets in PQsendQueryPrepared ... The PQsendQueryPrepared function transmits the sequence BIND -> DESCRIBE(PORTAL) -> EXECUTE -> SYNC. However, libpq does not indicate whether the DESCRIBE PORTAL step produces a NoData packet for commands such as INSERT, DELETE, or UPDATE. In these cases, libpq returns PGRES_COMMAND_OK, whereas SELECT statements yield PGRES_SINGLE_TUPLE or PGRES_TUPLES_OK. This update explicitly appends a NoData packet to the result in order to provide consistent behavior across query types.	8 months ago

Rahim Kanji	bc87d0d901	* For a Describe Portal message, peek at the next message in the extended query frame.

Javier Jaramago Fernández	6f2798abe0	Fix memory leak in 'ProxySQL_Admin::stats___mysql_global' - Closes #4976 ... The resource leak was associated to prepared statements (sqlite3_stmt). Since the detection of these leaks is tricky, because the resources held by 'SQLite3' never lose their references, a helper type ('stmt_unique_ptr') and a safer variation for 'prepare_v2' have been introduced. This helper type should automatically handle the lifetime of the statements, avoiding these kind of leaks in the future. The non-safe alternative has been flagged as 'deprecated', so it can be easily identified in later refactors or slowly removed during development.	10 months ago

René Cannaò	f9575b7ee9	Addressing minor issue on Readyset Monitoring ... - Renamed ReadySet to Readyset - fixed incorrect status variable - added missing newlines	12 months ago
René Cannaò	d641ca89be	First POC for integration with ReadySet ... Monitor is able to detect if a backend is a ReadySet server, and it enables special monitoring. The special monitoring hacks replication lag checks: a ReadySet server is "monitored for replication lag" , but it has a special query and a special handler. The query for check is "SHOW READYSET STATUS" , and the `Status` line is processed: * Online: the backend is configured as ONLINE * Maintenance* : the backend is configured as OFFLINE_SOFT * anything else, or failed check: SHUNNED A new monitor table is also added: `readyset_status_log` . It has a similar structure of `mysql_server_replication_lag_log` , but instead of storing `repl_lag` (replication lag) the full output of `SHOW READYSET STATUS` is saved as a JSON (that can be queried using `JSON_EXTRACT()`	12 months ago
