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	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	d2c333dcfd	Special handling of PostgreSQL DateStyle in ProxySQL ... - DateStyle consists of two values: a format and an order (e.g., ISO, MDY). Unlike other parameters, DateStyle can be set with one or both values, and the missing value retains its previous setting. Examples: SET DateStyle TO 'ISO, MDY' → Format: ISO, Order: MDY SET DateStyle TO 'ISO' → Format: ISO, Order remains unchanged i.e MDY SET DateStyle TO 'DMY' → Format remains unchanged i,e ISO, Order: DMY SET DateStyle TO 'Postgres' → Format: Postgres, Order remains unchanged i.e DMY Improved RESET statements and DEFAULT parameter values handling - Enhance RESET and DEFAULT value handling: • When a parameter is RESET or set to DEFAULT, ProxySQL now first checks if a value is provided in the connection options. • If a connection value is specified, it is applied; otherwise, the parameter falls back to the value defined by the corresponding pgsql-default_* variable.	1 year ago
