Rene Cannao	c2f678a9de	feat: implement release tiers and feature guards for v3.0, v3.1, and v4.0 This commit introduces a structured release tier system controlled by environment variables, allowing three distinct ProxySQL versions to be built from the same codebase while maintaining a clear upgrade path. Key Changes: - Tier 1 (v3.0.x Stable): Default build including bug fixes and core enhancements. - Tier 2 (v3.1.x Innovative): Enabled via PROXYSQL31=1. Adds FFTO and TSDB. - Tier 3 (v4.0.x AI/MCP): Enabled via PROXYSQLGENAI=1. Adds the AI stack. Implementation Details: - Makefile: Implemented dynamic versioning logic that increments the minor version for v3.1 and the major version for v4.0. Added tier documentation. - Feature Guards: Introduced PROXYSQLFFTO and PROXYSQLTSDB guards across ProxySQL_Admin, ProxySQL_Statistics, REST API, and HTTP server. - FFTO: Guarded Fast Forward Traffic Observer in MySQL and PgSQL sessions, including thread-local variables and configuration parameters. - TSDB: Guarded the entire Time Series Database subsystem, including SQLite table definitions, background loops, and REST API endpoints. - Build Fixes: * Fixed 'proxy_debug_func' linkage by adding extern "C" and moving the definition outside of DEBUG guards to ensure non-debug builds link correctly. * Corrected misplaced/nested DEBUG and PROXYSQLFFTO guards. * Verified build stability for all tiers (unset, PROXYSQL31=1, PROXYSQLGENAI=1).	1 month ago
Wazir Ahmed	5421a382ab	fix: Load TSDB variables from disk during startup - TSDB variables stored on disk were not being loaded into runtime during startup. Add the missing `flush_tsdb_variables___database_to_runtime()` and invoke it during init. - Inline the existing load/save wrappers in the header as thin delegations to the underlying flush functions Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	1 month ago

Rene Cannao	70b61a86e3	MCP stats: implement in-memory show_queries Top-K path Replace stats table reads in show_queries with Query Processor in-memory aggregation to avoid stale/empty admin-db snapshots.\n\nIntroduce Top-K digest filtering primitives and wire them into Stats_Tool_Handler so filtering/sorting/limit are executed against live digest memory. Add runtime MCP variable mcp-stats_show_queries_max_rows with validation, defaulting, and configuration plumbing, plus cap metadata in the tool response.\n\nEnforce configurable hard cap semantics while preserving deterministic ordering and pagination behavior for MCP clients. Add internal DEBUG validator path (PROXYSQLTEST 56) in admin tests to stress generated digest data and validate the Top-K/filter pipeline against in-memory state.\n\nKeep the validator callable from startup/testing workflows without depending on MCP linkage. Add TAP coverage in test/tap/tests/mcp_show_queries_topk-t.cpp for:\n- MCP endpoint setup and reachability\n- digest generation + optional DEBUG internal validator\n- payload validation and cap metadata assertions\n- descending count order validation\n- match_digest_text filter verification\n\nMake payload parsing backward-compatible in TAP (direct tool result object and legacy wrapped success/result payloads).	2 months ago

Rene Cannao	6a788e48c4	mcp: make /mcp/query self-healing when targets/backends appear after startup Problem addressed: - MCP query endpoint could stay unusable with 'Tool Handler not initialized' after restart/reload flows. - This was triggered when Query_Tool_Handler could not build an executable pool at init time (for example profiles loaded before ONLINE servers), leaving runtime commands like 'LOAD MCP QUERY RULES FROM MEMORY' blocked behind a NULL query tool handler. - Users had to manually toggle MCP enablement to recover, which is the opposite of expected self-healing behavior. What this commit changes: 1) Query_Tool_Handler pool init is now resilient and idempotent - init_connection_pool() now starts with close() so reinitialization fully resets stale mysql/pgsql pool state before rebuilding from runtime profile + server tables. - If no executable targets are available, init_connection_pool() now returns success with a warning instead of hard failure. This allows the query tool handler (and /mcp/query endpoint) to stay initialized even before backends are ready. 2) Lazy auto-rebuild on first query usage - get_connection() and get_pgsql_connection() now: - refresh target registry before resolution, - attempt to use an existing pooled connection, - if unavailable, trigger a full pool rebuild (init_connection_pool()) and retry once. - This provides automatic recovery when hostgroups/servers/profiles are loaded or changed after MCP startup, without requiring manual MCP disable/enable. 3) Admin runtime rule load path attempts MCP recovery - load_mcp_query_rules_to_runtime() now detects NULL query tool handler and calls load_mcp_server() once before failing. - This turns a hard, immediate admin error into a self-recovery attempt consistent with MCP runtime semantics. Behavioral impact: - /mcp/query endpoint remains online even when there are temporarily zero executable targets. - As soon as compatible runtime targets/backends exist, run_sql_readonly/explain_sql can recover automatically on demand. - LOAD MCP QUERY RULES TO/FROM RUNTIME no longer fails immediately on first NULL handler condition; it retries after MCP server recovery. Validation performed: - Recompiled modified objects successfully: - lib/obj/Query_Tool_Handler.oo - lib/obj/ProxySQL_Admin.oo - Full TAP runtime test execution is not possible in this sandbox due blocked local TCP socket creation; validation should be run in the normal test environment where ProxySQL/MySQL/PGSQL are reachable.	2 months ago
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.	2 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.	2 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.	2 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.	2 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.
