Rene Cannao	81c53896bc	Fix MCP module TAP test failures ... - Add MCP variables to load_save_disk_commands map for LOAD/SAVE commands - Add MCP variable validation in is_valid_global_variable() for SET commands - Implement has_variable() method in MCP_Threads_Handler - Add CHECKSUM command handlers for MCP VARIABLES (DISK/MEMORY/MEM) Test results improved from 28 passed / 16 failed to 49 passed / 3 failed. Remaining 3 failures are test expectation issues (boolean representation).	1 month ago
Rene Cannao	87fff9e046	Add MCP (Model Context Protocol) module skeleton ... Add new MCP module supporting multiple MCP server endpoints over HTTPS with JSON-RPC 2.0 protocol skeleton. Each endpoint (/mcp/config, /mcp/observe, /mcp/query, /mcp/admin, /mcp/cache) is a distinct MCP server with its own authentication configuration. Features: - HTTPS server using existing ProxySQL TLS certificates - JSON-RPC 2.0 skeleton implementation (actual protocol TBD) - 5 MCP endpoints with per-endpoint auth configuration - LOAD/SAVE MCP VARIABLES admin commands - Configuration file support (mcp_variables section) Implementation follows GenAI module pattern: - MCP_Threads_Handler: Main module handler with variable management - ProxySQL_MCP_Server: HTTPS server wrapper using libhttpserver - MCP_JSONRPC_Resource: Base endpoint class with JSON-RPC skeleton	1 month ago
Rene Cannao	efe0d4fe61	Add extensive doxygen documentation for vacuum_stats and stats_pgsql_stat_activity ... This commit documents: 1. The vacuum_stats() function's purpose, behavior, and the reason why stats_pgsql_stat_activity is excluded from bulk deletion operations 2. The fact that stats_pgsql_stat_activity is a SQL VIEW (not a table) and attempting DELETE on it would cause SQLite error: "cannot modify stats_pgsql_stat_activity because it is a view" The documentation explains: - Why TRUNCATE stats_mysql_query_digest triggers vacuum_stats(true) - Why both MySQL and PostgreSQL tables are cleared regardless of protocol - How the view is automatically cleared via its underlying table stats_pgsql_processlist - The importance of keeping the view excluded from deletion lists	2 months ago

Wazir Ahmed	5219d4be93	processlist: Prevent crash due to SQLITE_TOOBIG ... - Add new mysql/pgsql variable `processlist_max_query_length`. - Min: 1K - Max: 32M - Default: 2M - Truncate current query based on the configuration before inserting into `stats_*_processlist` tables. - Refactor/fix code related to other processlist configurations. 1. `session_idle_show_processlist` value was not updated in `ProxySQL_Admin.variables`. 2. Pass processlist config as an argument to `MySQL_Threads_Handler::SQL3_Processlist` instead of using thread-local variables. Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	4 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	7 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.	1 year ago
