René Cannaò	efedd93c92	Rename stats_global to stats_proxysql_global to avoid strstr substring collision stats_global is a substring of stats_mysql_global and stats_pgsql_global, causing the strstr-based dispatch to match incorrectly. Exclusion guards don't work either because a query referencing both tables would suppress the stats_proxysql_global refresh. Renaming to stats_proxysql_global follows the existing naming convention (stats_mysql_global, stats_pgsql_global) and eliminates the substring collision entirely.	3 weeks ago

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

Rene Cannao	6db089883e	fix(admin): improve PGSQL eventslog dump failure reporting and stats insert path Admin command behavior: - `DUMP PGSQL EVENTSLOG ...` returned `OK 0` when `GloPgSQL_Logger` was null. - This masked unavailable logger state from operators. Change: - Return an explicit admin error (`PgSQL logger not initialized`) when logger is unavailable. - Preserve normal `OK` response path when logger is present. Stats path behavior: - PgSQL logger metrics insertion into `stats_pgsql_global` used per-row string formatting and `execute()` calls. Change: - Replace per-row dynamic SQL construction with a prepared-statement row insert path. - Reuse `sqlite3_global_stats_row_step()` for consistent binding/reset semantics.	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	7c0ff770f6	refactor: migrate prepare_v2 SIMPLE cases in ProxySQL_Admin_Stats.cpp Migrated all prepare_v2 calls to RAII-based pattern in 5 functions: - stats___mysql_processlist(): 2 statements (statement1, statement32) - stats___pgsql_processlist(): 2 statements - stats___mysql_free_connections(): 2 statements - stats___mysql_query_rules(): 2 statements - stats___mysql_query_digest(): 2 statements And removed manual finalization calls for all functions. The RAII pattern ensures automatic cleanup and eliminates manual (*proxy_sqlite3_finalize) calls.	2 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`.	5 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.	10 months ago
