Rene Cannao	998bd82387	MCP TAP startup: fix tool-handler initialization order, improve MCP PROFILES observability, and seed monitor users This change fixes recurring MCP TAP failures where `/mcp/query` returned: Tool Handler not initialized for endpoint: query and where backend monitor auth failures flooded logs. Problem summary - MCP server startup can occur before runtime target/auth profiles and backend server mappings are loaded. - If that happens, Query_Tool_Handler initialization sees no executable targets and remains NULL. - MCP endpoint resources bind the handler pointer at creation time, so a NULL query handler at startup breaks `/mcp/query` until server restart. Code changes 1) Add explicit admin command logging for MCP PROFILES commands - Added `Received <command>` logging in the MCP PROFILES command block, matching behavior of other admin command handlers. - File: `lib/Admin_Handler.cpp` 2) Trigger MCP server refresh after `LOAD MCP PROFILES TO RUNTIME` - After copying profiles into runtime and rebuilding target/auth map, call `ProxySQL_Admin::load_mcp_server()`. - This allows MCP to self-heal when profiles become available after initial startup. - File: `lib/Admin_Handler.cpp` 3) Restart MCP server when query handler is missing - Extended `ProxySQL_Admin::load_mcp_server()` restart checks to include: - running server + `query_tool_handler == NULL` - Restart reason now includes tool handler initialization mismatch. - File: `lib/ProxySQL_Admin.cpp` 4) Fix TAP configurator load order to avoid early MCP startup - Reordered `test/tap/tests/mcp_rules_testing/configure_mcp.sh` runtime sequence: - `LOAD MYSQL SERVERS TO RUNTIME` - `LOAD PGSQL SERVERS TO RUNTIME` (best effort) - `LOAD MCP PROFILES TO RUNTIME` - `LOAD MCP VARIABLES TO RUNTIME` (last) - This ensures MCP starts only after routing/auth context is present. 5) Seed monitor credentials in AI local infra pre-hook - Added backend user/role creation for default monitor credentials `monitor/monitor`: - MySQL: create user + monitor-relevant grants - PostgreSQL: create role + `pg_monitor` + DB connect grants - Reduces monitor auth noise in local AI TAP dockerized setup. - File: `test/tap/groups/ai/pre-proxysql.bash` 6) Mark new TAP phase scripts executable - `test_phase10_eval_explain.sh` - `test_phase11_pgsql_target.sh` Expected outcome - MCP query endpoint no longer stays stuck with an uninitialized tool handler after TAP configuration. - MCP query-rules admin commands stop failing due to missing Query_Tool_Handler. - MCP profile command flow is visible in logs for easier debugging. - Local AI TAP infra no longer emits continuous monitor authentication failures for default monitor credentials.	4 months ago
Rene Cannao	af0411bd46	MCP: add target-aware rules/stats tests, explain_sql rule coverage, and AI local docker TAP infra This commit completes end-to-end MCP query-rules validation for multi-target routing and introduces a self-contained TAP infra for the `ai` group that can run both in Jenkins and manually. Main MCP/runtime changes: - Extended MCP query-rule matching context to include both `target_id` and resolved backend `username`. - Added `target_id` column to `mcp_query_rules` and `runtime_mcp_query_rules` table definitions. - Extended `stats_mcp_query_rules` to include `username` and `target_id` alongside `rule_id` and `hits`. - Updated load/save/runtime refresh paths to persist and rehydrate the expanded MCP rule schema. - Wired the rule engine into `explain_sql` so MCP rules apply consistently across `run_sql_readonly` and `explain_sql`. - Included startup-order fix in `src/main.cpp` to initialize MCP/GenAI thread handlers early, preventing startup crashes in PROXYSQLGENAI builds. Test coverage changes: - Updated existing MCP TAP phases to assert target-aware and username-aware behavior: - `test_phase4_stats.sh` - `test_phase6_eval_block.sh` - Added new MCP TAP phases: - `test_phase10_eval_explain.sh` (rule engine coverage for `explain_sql`) - `test_phase11_pgsql_target.sh` (pgsql target routing/rule/stats coverage; graceful skip if no pgsql target is configured) - Updated `test_mcp_query_rules-t.sh` runner to execute new phases. AI group isolated infra (manual + CI compatible): - Added `test/tap/groups/ai/docker-compose.yml` with MySQL 9.0 and PostgreSQL 16 backends. - Added lifecycle scripts: - `docker-compose-init.bash` - `docker-compose-destroy.bash` - `pre-proxysql.bash` - `post-proxysql.bash` - Extended `test/tap/groups/ai/env.sh` with local default ports/credentials/target IDs used by MCP TAP tests. - Added `test/tap/groups/ai/README.md` documenting manual execution flow outside Jenkins. Outcome: - MCP tests now validate routing-aware rule enforcement and stats attribution for both MySQL and PostgreSQL targets. - The `ai` TAP group can be run with an isolated local backend stack without relying on external Jenkins infra repositories.	4 months ago
Rene Cannao	013864b36f	MCP: introduce profile-based target/auth routing and unified LOAD/SAVE MCP PROFILES commands This commit introduces the core MCP routing architecture that decouples client-facing target selection from backend connection details. Architecture introduced: - New MCP auth profile table to store backend credentials/policy (`mcp_auth_profiles`). - New MCP target profile table to map opaque `target_id` -> protocol/hostgroup/auth profile (`mcp_target_profiles`). - Runtime mirrors for both profile tables. Behavioral changes: - MCP query tools resolve execution context by `target_id` and route internally by protocol + hostgroup. - Client no longer needs backend-specific connection details; only logical target identifiers. - Unified admin commands for profile lifecycle management: - `LOAD MCP PROFILES TO/FROM MEMORY/RUNTIME/DISK` - `SAVE MCP PROFILES TO/FROM MEMORY/RUNTIME/DISK` Design goals: - Support multi-backend MCP execution (MySQL + PostgreSQL) behind one endpoint. - Provide server-side credential management and cleaner operational model. - Replace legacy one-backend POC configuration with scalable target/auth abstractions. Result: - MCP routing is now dynamic, protocol-agnostic at the client layer, and fully managed through profile tables and unified load/save commands.	4 months ago

Rene Cannao	3c85c593cf	Add GloMTH initialization wait to all monitor and server threads Fix race condition where threads were accessing GloMTH before it was fully initialized, causing Valgrind errors in get_variable_int() and related functions. Added wait loop pattern (while GloMTH==NULL { usleep(50000); }) followed by usleep(100000) to ensure GloMTH is fully initialized before use: In lib/MySQL_Monitor.cpp: - monitor_connect(), monitor_ping(), monitor_read_only() - monitor_group_replication(), monitor_galera(), monitor_replication_lag() - monitor_AWS_Aurora_thread_HG(), monitor_aws_aurora() - init_mysql_thread_struct() In src/SQLite3_Server.cpp: - SQLite3_Server_session_handler In lib/ProxySQL_Admin.cpp: - admin_session_handler In lib/ClickHouse_Server.cpp: - ClickHouse_Server_session_handler The pattern ensures threads wait for GloMTH initialization during startup, then check for NULL during shutdown to exit cleanly.	5 months ago
Rene Cannao	ee7ee0b387	Fix multiple Valgrind-reported uninitialized memory issues 1. MySQL_Logger.cpp: Add NULL checks for myconn->parent before accessing address/port. Client connections (frontend) have parent=NULL, causing uninitialized value reads when logging. 2. debug.cpp: Add NULL check for GloVars.global.gdbg_lvl before accessing debug level configuration. Prevents use of uninitialized data when proxy_debug_func is called before init_debug_struct() completes. 3. ProxySQL_Admin.cpp: Add NULL checks for debug filter database fields before constructing filter strings. Prevents undefined behavior when constructing std::string from NULL pointers.	5 months ago

Rene Cannao	3ab964010d	Add protocol labels to Query Cache metrics and enable PostgreSQL QC metrics This commit resolves the prometheus metric collision between MySQL and PostgreSQL Query Cache instances by creating separate metric maps with protocol labels and using compile-time type trait selection. Changes: - Add #include <type_traits> to Query_Cache.cpp - Create qc_metrics_map_mysql with { "protocol", "mysql" } labels (8 metrics) - Create qc_metrics_map_pgsql with { "protocol", "pgsql" } labels (8 metrics) - Modify Query_Cache constructor to use if constexpr with std::is_same_v to select the appropriate metrics map based on derived type - Enable GloPgQC metrics export in update_modules_metrics() This allows MySQL and PostgreSQL query cache metrics to coexist without collision, following the same pattern as Thread Handler metrics.

Rene Cannao	709649232b	fix: Address AI code review concerns from PR #19 This commit addresses valid concerns raised by coding agents (Gemini, Copilot, CoderabbitAI): 1. Fix stats_mcp_query_digest naming conflict (ProxySQL_Admin.cpp): - Made reset and non-reset paths mutually exclusive using else block - Prevents both flags from being true, matching MySQL pattern - Ensures reset takes precedence over non-reset 2. Fix INSERT OR REPLACE sync issue (Admin_Handler.cpp): - Added DELETE before INSERT OR REPLACE in LOAD/SAVE MCP QUERY RULES - Prevents stale rules from persisting when syncing disk <-> memory - Ensures deleted source rows are also removed from target 3. Fix integer division truncation for timeout (Query_Tool_Handler.cpp): - Changed timeout_ms/1000 to (timeout_ms+999)/1000 for ceiling division - Ensures sub-second timeouts (e.g., 500ms) become at least 1 second - Prevents zero-second timeouts from causing unexpected behavior 4. Remove confusing comment (Discovery_Schema.cpp): - Simplified column count comment to be clear and accurate Note: The re_modifiers parsing code already correctly handles VARCHAR "CASELESS" to int conversion (lines 2414-2425), so that review comment was already addressed.	5 months ago

Rene Cannao	5a85ef04f6	Fix MCP variables persistence and add DISK command support This commit fixes several issues with MCP (Model Context Protocol) variables not being properly persisted across storage layers and adds support for DISK commands. Changes: 1. lib/Admin_FlushVariables.cpp: - Fixed flush_mcp_variables___runtime_to_database() to properly insert variables into runtime_global_variables using db->execute() with formatted strings (matching admin pattern) - Fixed SQL format string to avoid double-prefix bug (qualified_name already contains "mcp-" prefix) - Fixed lock ordering by releasing outer wrlock before calling runtime_to_database with use_lock=true, then re-acquiring - Removed explicit BEGIN/COMMIT transactions to match admin pattern 2. lib/Admin_Handler.cpp: - Added MCP DISK command handlers that rewrite commands to SQL queries: * LOAD MCP VARIABLES FROM DISK -> INSERT OR REPLACE INTO main.global_variables * SAVE MCP VARIABLES TO DISK -> INSERT OR REPLACE INTO disk.global_variables * SAVE MCP VARIABLES FROM MEMORY/MEM -> INSERT OR REPLACE INTO disk.global_variables - Separated DISK command handlers from MEMORY/RUNTIME handlers 3. lib/ProxySQL_Admin.cpp: - Added flush_mcp_variables___runtime_to_database() call to stats section to ensure MCP variables are repopulated when runtime_global_variables is cleared and refreshed 4. tests/mcp_module-t.cpp: - Added verbose diagnostic output throughout tests - Added section headers and test numbers for clarity - Added variable value logging and error logging All 52 MCP module tests now pass.	6 months 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	6 months ago
