Rene Cannao	77fe2addd4	feat: wire PgBouncer compat into ProxySQL admin and CLI (#5564 , #5565 ) Integration of PgBouncer migration tooling into ProxySQL core: 1. Admin command (Admin_Handler.cpp): - IMPORT PGBOUNCER CONFIG FROM '/path' [DRY RUN] [IGNORE WARNINGS] - Parses PgBouncer config, converts to SQL, executes against admin DB - DRY RUN returns converted SQL as a result set - Strict mode (default) fails on unmappable parameters - IGNORE WARNINGS allows partial conversion 2. PgBouncer SHOW commands (Admin_Handler.cpp): - Intercepts SHOW POOLS/STATS/SERVERS/CLIENTS/DATABASES/USERS/CONFIG/ VERSION/STATE/LISTS on PgSQL admin port - Translates to equivalent ProxySQL SQL with PgBouncer-exact columns - SHOW EXTENDED variant adds ProxySQL-specific columns - Unsupported commands return descriptive error messages - Only active on PgSQL sessions (if constexpr guard) 3. proxysql-cli mode (main.cpp): - Detects argv[0] == "proxysql-cli" at start of main() - Routes to proxysql_cli_main() which never starts the daemon - Symlink: ln -s proxysql proxysql-cli 4. Headers copied to include/ following ProxySQL convention.	4 days ago

René Cannaò	9850d9daeb	Fix stats_global substring collision and reload failure tracking 1. stats_global strstr match: add exclusion guards for stats_mysql_global and stats_pgsql_global to prevent spurious stats___global() calls and unnecessary ssl_mutex contention on every MySQL/PgSQL global stats query. 2. TLS reload failure tracking: set tls_last_load_ok=false and update tls_load_count/tls_last_load_timestamp on non-bootstrap reload failures. Previously, a failed PROXYSQL RELOAD TLS would leave stale SUCCESS status in stats_global.	2 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	5d45d17456	mcp stats: split connection metrics from debug free-pool snapshots Refactor MCP stats connection tools so operational pool metrics remain lightweight while debug-level free-connection details are exposed through a dedicated gated tool. Changes in this commit: - Updated stats tool catalog and dispatch to add show_free_connections and keep show_connections focused on per-server pool metrics only. - Removed free-connection payload from show_connections and added explicit compatibility error when callers still pass detail=true, with guidance to use show_free_connections. - Implemented show_free_connections using in-memory hostgroup manager snapshots (MySQL and PgSQL) with hostgroup/server filtering and summary counters. - Added MCP runtime variable mcp-stats_enable_debug_tools (default false), including variable registration, getter/setter handling, and config default in proxysql.cfg. - Added extensive doxygen comments across modified code paths to document behavior, rationale, filters, and output contracts. - Added TAP coverage in mcp_show_connections_commands_inmemory-t for: show_commands baseline, show_connections aggregate-only contract, debug tool gating behavior, and enabled-path validation for show_free_connections on both MySQL and PgSQL. - Registered the new TAP test in test groups.	2 months ago
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).	2 months 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	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	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	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.	2 months ago
