Rene Cannao	e762f91cda	MCP stats: add in-memory processlist filtering and PgSQL concurrency stress TAP Replace direct stats-schema reads in MCP show_processlist with in-memory processlist access via SQL3_Processlist query options. Add processlist query option types in proxysql_admin interfaces and implement filtering, sorting, and pagination post-processing in both MySQL and PgSQL thread implementations. Introduce configurable MCP cap mcp_stats_show_processlist_max_rows (default 200, max 1000), wire it through MCP variable loading, and expose it in default config. Expand Stats_Tool_Handler processlist handling to parse filter/sort arguments, enforce cap metadata, and return consistent MCP payload fields from in-memory snapshots. Add extensive doxygen documentation in the touched headers and source blocks to describe API contracts, filtering behavior, and runtime constraints. Add new TAP test mcp_pgsql_concurrency_stress-t that generates sustained concurrent PgSQL traffic (simple reads, read/write table workload, randomized pg_sleep) while polling MCP show_processlist and show_queries in parallel with filter and ordering assertions. Validation performed locally: mcp_pgsql_concurrency_stress-t (31 assertions) and mcp_show_queries_topk-t (12 assertions).	4 weeks 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).	4 weeks 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 weeks ago
Rene Cannao	200fdecb8d	Apply AI agent review fixes to PR #5374 Critical Fixes: - Fix NULL pointer dereferences in MySQL_Logger.cpp: * Add null checks for myds->myconn->parent in log_audit_entry() * Fix cleanup code in log_request() and log_audit_entry() * Change sprintf to snprintf for buffer safety - Remove redundant pthread_rwlock_init in debug.cpp: * filters_rwlock already initialized with PTHREAD_RWLOCK_INITIALIZER * Re-initialization caused undefined behavior per POSIX Major Improvements: - Add bounded wait helper wait_for_glo_mth() in proxysql_utils.h: * Replaces indefinite while loops with 10s timeout * Applied to 26 locations across 4 files Build System: - Require C++17 in Makefile (remove C++11 fallback): * Code uses C++17 structured bindings extensively * Cleanest solution vs adding fallback guards to 27+ locations Compilation fixes: - Add unistd.h include for usleep - Remove conflicting GloMyMon extern declaration Files changed: - Makefile - include/proxysql_utils.h - lib/MySQL_Logger.cpp - lib/debug.cpp - lib/MySQL_Monitor.cpp - lib/ProxySQL_Admin.cpp - lib/ClickHouse_Server.cpp - src/SQLite3_Server.cpp	1 month 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.	1 month ago

Rene Cannao	1af768f932	Fix critical issues in GenAI code (PR #5339 ) This commit addresses critical issues identified in the PR review: 1. Build system redundancy (src/Makefile): - Remove redundant PROXYSQLGENAI conditionals in linking commands - The flag doesn't affect linking, so simplify to PROXYSQLCLICKHOUSE only 2. Missing PROXYSQLGENAI guard (lib/Admin_Handler.cpp): - Add #ifdef PROXYSQLGENAI around MCP VARIABLES DISK commands - Ensures MCP commands are only available when GenAI is enabled 3. Broken retry logic (lib/LLM_Clients.cpp): - Remove misleading is_retryable_error() checks that used stale values - last_curl_code and last_http_code were never updated - Simplify to retry on empty responses only (documented limitation) - Fix thread-safety: use thread_local std::mt19937 instead of rand() 4. Resource leak (lib/MySQL_Tool_Handler.cpp): - Clean up previously created connections on init failure - Both mysql_init and mysql_real_connect error paths now clean up 5. Race condition (lib/Query_Tool_Handler.cpp): - Add missing pool_lock in find_connection() - Prevents race condition when accessing connection_pool Fixes identified by automated PR review agents.	1 month ago

Rene Cannao	03e58146ea	fix: Re-enable SQLite3DB::LoadPlugin() with allow_load_plugin flag This addresses an issue from PR #22 where LoadPlugin() was completely disabled. The function performs necessary initialization even when no plugin is loaded (initializes built-in sqlite3 function pointers). Changes: - Added `const bool allow_load_plugin = false` flag in LoadPlugin() - Modified `if (plugin_name)` to `if (plugin_name && allow_load_plugin == true)` - Re-enabled the LoadPlugin() call in LoadPlugins() The plugin loading code remains disabled (allow_load_plugin=false) while the function pointer initialization from built-in SQLite3 now works correctly.

Rene Cannao	245e61ee86	Make MCP_Threads_Handler a standalone independent class Remove unnecessary inheritance from MySQL_Threads_Handler. The MCP module should be independent and not depend on MySQL/PostgreSQL thread handlers. Changes: - MCP_Threads_Handler now manages its own pthread_rwlock_t for synchronization - Simplified init() signature (removed unused num/stack parameters) - Added ProxySQL_Main_init_MCP_module() call in main initialization phase - Include only standard C++ headers (pthread.h, cstring, cstdlib)	2 months 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	2 months ago

Rene Cannao	01d654692d	Integrate sqlite-rembed for text embedding generation Add support for sqlite-rembed Rust SQLite extension to enable text embedding generation from remote AI APIs (OpenAI, Nomic, Ollama, Cohere, etc.) within ProxySQL's SQLite3 Server. Changes: 1. Build system integration for Rust static library compilation - Rust toolchain detection in deps/Makefile - Static library target: sqlite3/libsqlite_rembed.a - Linking integration in lib/Makefile and src/Makefile 2. Extension auto-registration in Admin_Bootstrap.cpp - Declare sqlite3_rembed_init() extern C function - Register via sqlite3_auto_extension() after sqlite-vec 3. Documentation updates - doc/sqlite-rembed-integration.md: comprehensive integration guide - doc/SQLite3-Server.md: usage examples and provider list 4. Source code inclusion - deps/sqlite3/sqlite-rembed-source/: upstream sqlite-rembed v0.0.1-alpha.9 The integration follows the same pattern as sqlite-vec (static linking with auto-registration). Provides rembed() function and temp.rembed_clients virtual table for embedding generation. Build requires Rust toolchain (cargo, rustc) and clang/libclang-dev.	3 months ago
Rahim Kanji	c0f99c0e15	Refactor: Improved Prepared-Statement Cache Design (Lock-Free Hot Path) #5211 Concurrency and Memory Management * Lock-Free Ref Counting: Replaced global mutex-protected integer reference counts with `std::atomic<uint32_t>` within `PgSQL_STMT_Global_info`, eliminating lock contention during statement referencing. * Modern Ownership: Adopted std::shared_ptr<const PgSQL_STMT_Global_info> for global and local storage, providing automatic, thread-safe memory and lifecycle management. * Memory Optimization: Removed redundant auxiliary maps `global_id_to_stmt_names` and `map_stmt_id_to_info` from local and global statement managers respectively, reducing overall memory overhead. * Optimized Purging: Statement removal logic was simplified for efficiently identifying and cleaning up unused statements. Hot Path Performance (`BIND`, `DESCRIBE`, `EXECUTE`) * Bypassed Global Lookups: Local session maps now store the `shared_ptr` directly, removing the need to acquire the global lock and search the global map during hot path operations. * Direct Refcount Manipulation: Refcount modification functions now operate directly on the passed statement object, eliminating the overhead of searching the global map to find the object pointer based on statement id. Safety and Protocol Logic (`PARSE`) * Efficient Statement Reuse: Implemented a local fast path check for the unnamed statement (`""`), allowing immediate reuse of an identical query (same hash) upon re-parse, which bypasses global processing and locks. Cleanup * Cleaned up and class rename `PgSQL_STMT_Manager_v14` -> `PgSQL_STMT_Manager`.	4 months ago
