Javier Jaramago Fernández	25d5681c61	Fix potential overflow for 'sqlite3_status' memory metrics ... The previous call have been replaced by 'sqlite3_status64' when querying 'SQLITE_STATUS_MEMORY_USED' to avoid potential integer overflows.	12 months ago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.	12 months ago

Rahim Kanji	720441af20	Refactored and Optimized Query Cache with PgSQL Support ... * Added Query Cache Support for PgSQL: * Introduced new variables for PgSQL Query Cache management: * pgsql-query_cache_size_MB * pgsql-query_cache_soft_ttl_pct * pgsql-query_cache_stores_empty_result * pgsql-query_cache_handle_warnings (not yet utilized) * Overwriting Transaction Status: * Sending current transaction state to the client when a result is returned from the query cache. * This currently does not differentiate between normal and error transaction states—both are treated as active transaction states. * Cache Lifetime Management: Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries, ensuring proper memory deallocation and reducing complexity. * Unified Purging Logic: Refactored the query cache purging logic to use a single thread for both MySQL and PgSQL cache entries. * Code Cleanup: Removed unnecessary methods and data members to streamline the codebase and improve maintainability. * Performance Optimization: Improved memory management, reducing memory footprint and enhancing performance.	2 years ago
