Wazir Ahmed	daa0b2037e	fix: Use consistent value representation in MCP query rules `mcp_query_rules` and `runtime_mcp_query_rules` uses different representations for the same fields, causing the web UI to always report config differences even after loading to runtime. - Use `-1` sentinel for nullable int fields (`flagOUT`, `timeout_ms`, `log`) so `NULL` values from main are preserved when written to runtime, following the `MySQL QP_rule_t` pattern. - Serialize `re_modifiers` bitmask back to `VARCHAR` (`1→"CASELESS"`) to match the format used in main table - Update `evaluate_mcp_query_rules()` to handle tri-state log field Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	1 month ago
Rene Cannao	70647fb426	fix: Remove unused legacy mcp-mysql_* variables These variables were deprecated in favor of profile-based routing but were never removed from the code. They existed in the struct definition, getters, and setters but were not consumed anywhere - Query_Tool_Handler uses target_auth_map via mcp_auth_profiles and mcp_target_profiles. Removed: - mcp-mysql_hosts, mcp-mysql_ports, mcp-mysql_user, mcp-mysql_password, mcp-mysql_schema from MCP_Thread.h struct - Variable names from mcp_thread_variables_names array - Initialization, cleanup, getters, and setters in MCP_Thread.cpp - Documentation in doc/MCP/VARIABLES.md	1 month ago

Rene Cannao	90462f6d5a	ffto: harden MySQL/PgSQL observer state handling and align tests/docs Address outstanding review findings for FFTO on v3.0-ff_inspect and tighten protocol-state correctness for both engines. MySQL FFTO - Restrict on_close() reporting to true in-flight states and always clear query tracking state after close. - Add explicit active-query cleanup helpers and invoke them on state transitions to IDLE. - Preserve accounting on mid-resultset server ERR packets by reporting current query in READING_COLUMNS/READING_ROWS before reset. - Keep prepared-statement lifecycle cleanup robust (pending prepare cleared on prepare completion paths). MySQL session integration - Extract duplicated FAST_FORWARD client FFTO feed logic into observe_ffto_client_packet() and reuse it from all call sites. PostgreSQL FFTO - Replace regex-based CommandComplete parsing with lightweight token parsing, including NUL/whitespace trimming and strict numeric validation. - Add queued tracking for pipelined extended-protocol executes so query text and response attribution stay aligned under Parse/Bind/Execute pipelining. - Distinguish finalize semantics (execute-finalize on CommandComplete vs sync-finalize on ReadyForQuery) and centralize finalize/activation helpers. - Add frontend Close ('C') handling to evict statement/portal mappings. - Harden client/server message parsing with additional length checks. - Extend affected-row command tag coverage to COPY and MERGE. TAP tests - Stabilize test plans for failure paths by replacing early returns with a fail-and-skip-remaining flow and shared cleanup labels. - Ensure both MySQL and PgSQL FFTO tests preserve planned assertion counts under setup/prepare/execute failures. Documentation - Align FFT0 design doc state/response descriptions with current implementation (ReadyForQuery handling, pipelined queueing, supported PG command tags). - Fix wording/typo issues in protocol section. Validation performed - make -C lib -j4 - make -C test/tap/tests test_ffto_mysql-t test_ffto_pgsql-t -j4 Runtime execution of the two TAP binaries remains environment-dependent (admin endpoint connectivity required).	1 month ago

Rene Cannao	1c25787b88	Introduce {mysql,pgsql}-query_processor_first_comment_parsing variable (#5384 ) This universal fix allows controlling when the first comment of a query is processed relative to the query rules. By setting this variable to 1, ProxySQL-specific annotations (like GTID) can be parsed immediately, allowing subsequent query rules to strip them from the query string. This prevents prepared statement cache bloat and improves backend statement reuse when annotations with unique literals are used.	2 months 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	c126e63a23	mcp stats: refresh stats tables under admin mutex before direct reads Problem MCP stats tools were querying stats.* tables directly through admindb. Unlike admin-session SQL, that path bypassed GenericRefreshStatistics() and could return stale or empty data for runtime-populated tables. What changed - Updated Stats_Tool_Handler::execute_admin_query() to mirror admin-session semantics for stats reads: - acquire GloAdmin->sql_query_global_mutex - optionally invoke ProxySQL_Admin::GenericRefreshStatistics(sql, ..., false) - execute admindb statement - release sql_query_global_mutex - Added strict input validation and explicit lock/unlock error reporting. - Added refresh_before_query parameter (default true) to avoid duplicate refresh passes for secondary count queries. - Switched secondary COUNT(*) calls in show_processlist/show_queries/ show_errors/show_query_rules to refresh_before_query=false. Documentation - Expanded Doxygen in include/Stats_Tool_Handler.h for execute_admin_query() to document locking, refresh behavior, and performance tradeoff. - Added detailed Doxygen above the execute_admin_query() implementation in lib/Stats_Tool_Handler.cpp. Testing - Added TAP integration test test/tap/tests/mcp_stats_refresh-t.cpp. - The test injects a synthetic stale marker row into stats.stats_mysql_global, calls /mcp/stats show_status, and verifies the marker disappears after refresh-before-read. - Added helper-level Doxygen in the test for setup/parsing behavior. Build verification - Compiled lib object: make -C lib obj/Stats_Tool_Handler.oo - Compiled TAP target: make -C test/tap/tests mcp_stats_refresh-t - Direct runtime execution of the TAP test in this workspace could not fully run because no local admin listener was available (connection to 127.0.0.1:6032 failed).	2 months ago

Rene Cannao	0aa3c5e153	fix(pgsql-eventslog): harden event ownership and keep newest rows in memory table Problem 1: - `PgSQL_Event::set_error()` stored borrowed pointers from connection-owned strings. - This could create lifetime hazards before/around event serialization and buffering. Fix: - Add explicit ownership tracking for error fields via `free_error_on_delete`. - Make `set_error()` duplicate incoming SQLSTATE/error strings. - Free owned error strings in destructor when the event does not own all fields. - Keep copy-constructor behavior for deep-copied buffered events and disable copy-assignment to avoid accidental shallow assignment. Problem 2: - `processEvents()` could repopulate `stats_pgsql_query_events` using the beginning of the drained batch after retention pruning. - This keeps older rows instead of the most recent rows when truncation is required. Fix: - Insert the tail of the drained batch (`events.end() - numEventsToInsert`) so memory table retention always preserves latest events. - Tighten row retention arithmetic using `size_t` to avoid signed/unsigned mismatch in keep/delete calculations.	2 months ago

Rene Cannao	caf324f911	logger: harden buffered logging flush/rotation semantics This commit addresses three correctness regressions introduced by thread-local log buffering in PR #5364 (query logging performance): 1) stale logfile pointer/UAF race during concurrent rotate/close 2) stale logfile-open state after close 3) non-global flush behavior in admin/format-switch paths What was fixed - Make `flush_and_rotate()` consume the current logfile pointer under lock - Signature changed from `std::fstream` to `std::fstream&` - Prevents dereferencing a stale stream pointer captured before lock acquisition while another thread rotates/closes the file - Updated declaration/definition and all call sites - Add explicit synchronization for cross-thread buffer draining - Added `LogBufferThreadContext::buffer_lock` - Any path that appends or flushes a thread buffer now locks this mutex - Guarantees force-flush from admin/config paths cannot race with worker-thread appends on the same context - Restore global forced flush semantics where required - Extended `MySQL_Logger::flush` and `PgSQL_Logger::flush` to `flush(bool force = false)` - `force=false`: preserves existing low-overhead worker-loop behavior (per-thread timeout-based flush) - `force=true`: snapshots all known thread contexts and drains both events/audit buffers regardless of timeout - `flush_log()` now calls `flush(true)` before file rotation, so admin flush and format-switch operations no longer miss pending thread buffers - Avoid unintended rotation during forced draining - In `force=true` path, flush uses `rotate_fn=nullptr` - Drains buffered payload into the current file first - `flush_log()` then performs one controlled rotate/open step - Fix logfile state tracking after close - `events_close_log_unlocked()` and `audit_close_log_unlocked()` now set `logfile_open=false` when the stream is closed - Prevents write paths from treating a closed stream as open - Remove per-thread-context dependency during metadata header write - `events_open_log_unlocked()` now uses a local `LogBuffer` for metadata emission in format=1 instead of reusing a thread context buffer - Keeps open/rotate path independent from worker context lifecycle - Keep callers consistent and non-duplicative - Since `flush_log()` now force-drains internally, removed redundant explicit `flush()` calls from: - MySQL/PgSQL `eventslog_format` switch handlers - `ProxySQL_Admin::flush_logs` Behavioral outcome - No stale stream pointer use when close/rotate interleaves with flush - No false-positive logfile-open state after close - `FLUSH LOGS` and eventslog format switch now drain all known thread buffers before rotating, preventing dropped/misplaced buffered records Validation - Built modified objects directly - Ran full debug build with GENAI enabled: make clean && export PROXYSQLGENAI=1 && make debug -j24 Build completed successfully.	2 months ago

Rene Cannao	9685cdaa4b	mcp discovery: enforce target-scoped run model and add protocol-aware static harvesting (mysql+pgsql) Refactor the MCP query/discovery stack to remove prototype-era MySQL-only assumptions and make discovery/catalog semantics explicitly target-scoped. This commit is intentionally not backward compatible with legacy single-target catalog metadata. Key implementation details: - Discovery_Schema: - runs table now stores target_id, protocol, and server_version - resolve_run_id() now requires target_id and resolves schemas within target scope - create_run() now records target/protocol/server version - added legacy schema detection + destructive catalog table rebuild when old runs layout is found - fixed resultset lifetime/escaping issues in target-aware run resolution - New PostgreSQL static harvester: - added PgSQL_Static_Harvester class and build wiring - harvests schemas/objects/columns/indexes/fks/view definitions into Discovery_Schema - maps pg metadata to object_id-based insert APIs used by Discovery_Schema - Query_Tool_Handler: - constructor simplified to catalog_path only (no mcp-mysql_* runtime ctor deps) - discovery.run_static now requires target_id and dispatches protocol-aware harvester at runtime - catalog., agent.run_start, and llm. tool contracts now require target_id when resolving run_id - all run_id resolution call sites switched to resolve_run_id(target_id, ...) - list_schemas catalog query now scoped by target_id via runs join - digest logging path now resolves run_id in target context - ProxySQL_MCP_Server: - updated Query_Tool_Handler construction to new signature - Docs updated: - added explicit target_id scoping guidance for discovery/catalog/agent/llm workflows - clarified protocol-aware routing and noted legacy examples still present in large script docs Build validation: - Recompiled changed objects with PROXYSQLGENAI=1: - Query_Tool_Handler.oo - Discovery_Schema.oo - PgSQL_Static_Harvester.oo - ProxySQL_MCP_Server.oo	2 months ago
Rene Cannao	f4bc1943fb	mcp query diagnostics: restore strict ONLINE requirement and explain target non-executable failures This change does two things: 1) Reverts executable-target policy to strict ONLINE backend status - Query target resolution in Query_Tool_Handler is restored to require UPPER(status)='ONLINE' in runtime_mysql_servers/runtime_pgsql_servers. - This matches expected semantics: non-ONLINE backends should not be considered executable MCP targets. 2) Replaces generic non-executable errors with actionable diagnostics - Added Query_Tool_Handler::format_target_unavailable_error(target_id). - All query-tool paths that previously returned the generic: 'Target is not executable by this handler' now return a reasoned error with context, including: - target_id - protocol - hostgroup_id - auth_profile_id - concrete reason (for example: empty db_username in auth profile, or no ONLINE backend in runtime_*_servers) - Internal logs in get_connection()/get_pgsql_connection() now emit the same detailed reason. 3) Improves MCP endpoint failure logging with SQL/target context - In MCP_JSONRPC_Resource::handle_tools_call(), failed tool calls now log: - endpoint/tool/error - full arguments payload (existing) - additional parsed details when present: target_id, schema, sql (trimmed for safety) - This makes it explicit what SQL was requested when a tool call fails before execution. 4) Protocol normalization retained for robustness - MCP_Threads_Handler::load_target_auth_map() lowercases protocol values when loading runtime profile joins. - This avoids protocol-casing drift causing inconsistent routing behavior. Build validation: - Successfully recompiled modified objects: - lib/obj/Query_Tool_Handler.oo - lib/obj/MCP_Endpoint.oo - lib/obj/MCP_Thread.oo Resulting behavior expected on next test run: - If a target is non-executable, the response and logs will state exactly why (ONLINE/backend/auth reason), instead of a generic error. - Failure logs will also include the attempted SQL text (for tool calls that carry sql arguments), clarifying whether a backend query was actually executed or blocked before execution.	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
