Rahim Kanji	28931cd00d	* Replaced malloc with std::vector for safer memory management. ... * Marked functions ref_count_client and ref_count_server as noexcept since standard exceptions are not being handled and application crashes are acceptable in such cases.	9 months ago
Rahim Kanji	3619fa5d21	Added pgsql-max_stmts_per_connection variable	9 months ago
Rahim Kanji	7c71fe1a05	Prevent overwrite of named statements ... Previously, issuing a PARSE with an existing statement name would silently overwrite the prepared statement. This fix ensures that named prepared statements cannot be overwritten and will raise an error if redefined. Only unnamed statements (empty name) are allowed to be replaced on reissue.	9 months ago

Rahim Kanji	dd1c7441f3	* Use C++17 if-initializers for map lookups ... * Assert if client_stmt_name already exists in stmt_name_to_global_ids (PgSQL_STMTs_local_v14::client_insert) * Assert if client_stmt_name is already mapped to same global_stmt_id in global_id_to_stmt_names (PgSQL_STMTs_local_v14::client_insert) [only in Debug]	9 months ago
Rahim Kanji	b989fc2bad	Refined Bind Message parameter format, value handling, and result format iterator	9 months ago
Rahim Kanji	06383750b3	Fixed SonarQube warnings where applicable	9 months ago
Rahim Kanji	bc87d0d901	* For a Describe Portal message, peek at the next message in the extended query frame. If it is an Execute message, indicating that client is sending a Bind/Describe/Execute sequence ... skip processing the Describe Portal. This is because libpq automatically includes a Describe Portal during execution, and sending it again would be redundant. * Removed server_capabilities from PgSQL modules	9 months ago

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
