Rene Cannao	e3026cbc6f	Fix wrong index in connection cleanup loops (MySQL and PgSQL) This commit fixes a bug where connection cleanup loops were removing the wrong connection from the pool. The loops checked each connection by index (i), but when an expired connection was found, they removed index 0 instead of index i. This caused: - Fresh connections at index 0 to be incorrectly deleted - Expired connections to remain in the pool Fixed files: - lib/Base_HostGroups_Manager.cpp:2603 (MySQL) - lib/MySQL_HostGroups_Manager.cpp:2939 (MySQL) - lib/PgSQL_HostGroups_Manager.cpp:2782 (PgSQL) The fix changes `remove(0)` to `remove(i)` to remove the correct connection.

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.	3 months ago
Rene Cannao	b965fc6df4	Fix PROXYSQLGENAI build - resolve circular includes and missing headers This commit fixes compilation errors when building with PROXYSQLGENAI=1: Header file fixes: - Add missing #endif /* PROXYSQLGENAI */ before header guards in multiple headers - Remove #include cpp.h from GenAI headers to avoid circular dependencies Source file fixes: - Add #include proxysql.h to GenAI .cpp files that were missing it - Add #include Static_Harvester.h to Query_Tool_Handler.cpp for forward decl Build system fixes: - Remove vec.o from libproxysql.a (it's linked separately in src/Makefile) - Prevents duplicate symbol errors during linking Test files: - Rename MCP test files with .sh suffix to prevent make clean deletion Both build modes now work: - make build_lib_debug (without GenAI) - PROXYSQLGENAI=1 make build_lib_debug (with GenAI)	3 months ago

Rene Cannao	3ccfa2bcc1	Address AI code review feedback for PR #5313 This commit addresses concerns raised by AI code reviewers (gemini-code-assist, Copilot, coderabbitai) on the initial security fixes. Critical fixes: - Fix lock.release() → lock.unlock() in GenAI_Thread.cpp worker_loop (lock.release() detaches without unlocking, causing deadlock) - Add missing early return after schema validation failure in Query_Tool_Handler.cpp Code quality improvements: - Improve escape_string() memory management in MySQL_Tool_Handler.cpp: - Use std::string instead of new[]/delete[] for buffer management - Check return value of mysql_real_escape_string() for errors - Remove redundant validation checks in validate_sql_identifier functions (character class loop already rejects unsafe characters) - Add backslash escaping to escape_string_literal() for defense-in-depth - Improve column list validation in MySQL_Tool_Handler sample_rows(): - Replace blacklist approach with proper column identifier parsing - Allow qualified identifiers (table.column) - Allow AS aliases (column AS alias) - No longer rejects legitimate column names containing "JOIN" These changes improve robustness while maintaining the security posture of the original SQL injection fixes.	3 months ago
Rene Cannao	c914feb230	Fix security issues identified in PR #5312 code review This commit addresses critical and important security vulnerabilities found during comprehensive code review of the Gen AI features merge. Critical fixes: - SQL injection vulnerabilities in MySQL_Tool_Handler.cpp: - Added validate_sql_identifier() for schema/table validation - Added escape_string() for MySQL string escaping using mysql_real_escape_string - Fixed list_tables(), describe_table(), sample_rows(), sample_distinct() - SQL injection vulnerabilities in Query_Tool_Handler.cpp: - Added validate_sql_identifier_sqlite() for identifier validation - Added escape_string_literal() for SQLite string escaping - Fixed list_tables tool and catalog.get_relationships function - Use-after-free race condition in GenAI_Thread: - Changed shutdown_ from int to std::atomic<int> for proper memory ordering - Added additional shutdown check in worker_loop after popping request Important fixes: - Buffer overflow risks from sprintf usage: - Converted all sprintf() calls to snprintf() in GenAI_Thread.cpp - Converted sprintf() to snprintf() in MySQL_Session.cpp - Worker loop shutdown race condition: - Added shutdown check after popping request from queue - Properly clean up client_fd when shutdown is detected These fixes ensure: 1. All user input is properly validated before use in SQL queries 2. String values are properly escaped using database-specific escaping 3. Thread-safe shutdown with proper memory ordering guarantees 4.

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. TODO: Revisit plugin loading safety mechanism to allow actual plugin loading.	3 months ago

Rene Cannao	ffe5690360	fix: Address coderabbitai review - use-after-free, missing responses, SQL injection Fix issues identified by coderabbitai review: 1. Admin_Handler.cpp: Fix typo in strncasecmp for LOAD MCP QUERY RULES - Line 2365 had "LOAD MCP RULES FROM DISK" instead of "LOAD MCP QUERY RULES FROM DISK" 2. Admin_Handler.cpp: Fix use-after-free and missing client response - Removed l_free(ql,q) which freed q before caller used it - Added send_error_msg_to_client calls on all error paths - Added send_ok_msg_to_client call on success path - Changed return value from true to false (to match handler pattern) - Applied to both LOAD MCP QUERY RULES and SAVE MCP QUERY RULES handlers 3. ProxySQL_Admin_Stats.cpp: Fix sprintf SQL injection in stats___mcp_query_rules - Replaced sprintf with prepared statement using positional parameters - Changed from char query with malloc/free to sqlite3_stmt with prepare_v2 - Both columns now bound as parameters (?1, ?2)	3 months ago
Rene Cannao	5ece563514	fix: Correct SQL prepared statement API usage and template variable access Fix compilation errors in the SQL injection fixes: 1. ProxySQL_Admin_Stats.cpp: Use public statsdb->prepare_v2() API - Changed from direct proxy_sqlite3_prepare_v2() calls with statsdb->db - statsdb->db is private, must use public prepare_v2(query, &stmt) method 2. Admin_Handler.cpp: Add SPA cast for template function access - Added ProxySQL_Admin SPA=(ProxySQL_Admin )pa; declaration - Changed all admindb->execute to SPA->admindb->execute - Removed unused 'error' and 'success' variables The build now completes successfully.	3 months ago
Rene Cannao	9f07e9631e	fix: Use prepared statements in ProxySQL_Admin_Stats to prevent SQL injection Fix two SQL injection vulnerabilities identified by coderabbitai in ProxySQL_Admin_Stats.cpp by converting sprintf/snprintf interpolation to SQLite prepared statements. 1. stats___mcp_query_digest (lines 2581-2636): - Changed from sprintf with format string to prepared statement - digest_text field now properly bound as parameter (was unsafe) - All 10 columns now use positional parameters (?1-?10) 2. stats___mcp_query_tools_counters (lines 1587-1635): - Changed from snprintf with unescaped fields to prepared statement - Fixed incorrect table name logic (was appending _reset incorrectly) - All 8 columns now use positional parameters (?1-?8) These changes prevent SQL injection when resultset fields contain quotes, backslashes, or other SQL metacharacters.	3 months ago
Rene Cannao	3bcee22700	fix: Execute MCP query rules DELETE+INSERT as explicit transaction Fix multi-statement execution in Admin_Handler.cpp for MCP query rules. The previous code built a single SQL string with "DELETE ...; INSERT ..." but SQLite only executed the first statement. Changed to execute statements as an explicit transaction: 1. BEGIN 2. DELETE FROM target_table 3. INSERT OR REPLACE INTO target_table SELECT * FROM source_table 4. COMMIT (or ROLLBACK on error) Applied to both: - LOAD MCP QUERY RULES FROM DISK/TO MEMORY - SAVE MCP QUERY RULES TO DISK Addresses coderabbitai review comment.	3 months ago
Rene Cannao	188aef90fe	fix: Use delete instead of free for SQLite3_result in load_mcp_query_rules_to_runtime Change free(resultset) to delete resultset in ProxySQL_Admin::load_mcp_query_rules_to_runtime. SQLite3_result is a C++ class allocated with new, so it must be deallocated with delete, not free(). Using free() causes undefined behavior and memory leaks. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	bbc04974f1	fix: Fix mysql_query failure path and affected_rows race condition Fix two issues in Query_Tool_Handler's execute_query functions: 1. mysql_query() failure path now returns immediately after return_connection() instead of continuing to process on bad state. 2. Capture affected_rows BEFORE return_connection() to avoid race condition. Previously, mysql_affected_rows() was called after return_connection(), potentially accessing a stale connection. Apply fixes to both execute_query() and execute_query_with_schema(). Addresses coderabbitai review comments.	3 months ago
Rene Cannao	b3edc6524b	fix: Escape SQL strings in harvest_view_definitions Add escape_sql_string() helper function that doubles single quotes to prevent SQL injection when strings are used in SQL string concatenation. Update harvest_view_definitions to use this function for view_def, schema_name, and view_name. This prevents SQL injection in the UPDATE statement that stores view definitions in the catalog. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	6835713f11	fix: Correct column indexes in build_quick_profiles Fix off-by-one errors in row->fields indices. The SELECT clause returns: object_id(0), schema_name(1), object_name(2), object_type(3), engine(4), table_rows_est(5), data_length(6), index_length(7), has_primary_key(8), has_foreign_keys(9), has_time_column(10) But the code was reading from fields[3..9] instead of [4..10]. Added comment documenting the correct column order. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	e9abee625b	fix: Execute prepared statement in execute_parameterized_query The execute_parameterized_query function in RAG_Tool_Handler was creating a prepared statement and binding parameters, but then executing the raw query string instead of the prepared statement. This completely bypassed the parameter binding, making the function useless for preventing SQL injection. Changed to use vector_db->execute_prepared(stmt, ...) to execute the bound statement instead of the raw query, so the bound parameters are actually used. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	6305537ba8	fix: Use delete instead of free for SQLite3_result deallocation Change free(resultset) to delete resultset in Query_Tool_Handler (extract_schema_name function). SQLite3_result is a C++ class allocated with new, so it must be deallocated with delete, not free(). Using free() causes mixed allocator UB. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	5e121399aa	fix: Add AFTER UPDATE trigger to keep catalog_fts index in sync for upserts Add catalog_au AFTER UPDATE trigger in MySQL_Catalog that mirrors the delete+insert pattern used in catalog_ad/catalog_ai. This keeps the FTS index current when upserts occur (INSERT OR REPLACE ... ON CONFLICT ... DO UPDATE), since the UPDATE doesn't trigger INSERT/DELETE triggers. The trigger first deletes the old entry from catalog_fts then inserts the new entry, ensuring the full-text search index stays synchronized with the catalog table. Addresses coderabbitai review comment.	3 months ago
Rene Cannao	5dd5dbe6b7	fix: Add missing assert(proxy_sqlite3_bind_blob) in sqlite3db.cpp Add assert(proxy_sqlite3_bind_blob) to the assertion block in SQLite3DB::LoadPlugin to ensure the symbol is provided by plugins. Without this, if a plugin fails to provide the symbol, the code will crash at runtime with no safety check. proxy_sqlite3_bind_blob is actively used in Anomaly_Detector.cpp:765 to bind embeddings.

Rene Cannao	709649232b	fix: Address AI code review concerns from PR #19 This commit addresses valid concerns raised by coding agents (Gemini, Copilot, CoderabbitAI): 1. Fix stats_mcp_query_digest naming conflict (ProxySQL_Admin.cpp): - Made reset and non-reset paths mutually exclusive using else block - Prevents both flags from being true, matching MySQL pattern - Ensures reset takes precedence over non-reset 2. Fix INSERT OR REPLACE sync issue (Admin_Handler.cpp): - Added DELETE before INSERT OR REPLACE in LOAD/SAVE MCP QUERY RULES - Prevents stale rules from persisting when syncing disk <-> memory - Ensures deleted source rows are also removed from target 3. Fix integer division truncation for timeout (Query_Tool_Handler.cpp): - Changed timeout_ms/1000 to (timeout_ms+999)/1000 for ceiling division - Ensures sub-second timeouts (e.g., 500ms) become at least 1 second - Prevents zero-second timeouts from causing unexpected behavior 4. Remove confusing comment (Discovery_Schema.cpp): - Simplified column count comment to be clear and accurate Note: The re_modifiers parsing code already correctly handles VARCHAR "CASELESS" to int conversion (lines 2414-2425), so that review comment was already addressed.	3 months ago

Rahim Kanji	9b66224df1	Fix critical double-free bug, SQL injection vulnerability, and hardcoded path This commit addresses three issues identified by code review: 1. CRITICAL: Fix double-free bug in MCP server restart logic - Remove manual handler deletions in Admin_FlushVariables.cpp - ProxySQL_MCP_Server destructor already properly cleans up all handlers - Previously caused crashes when toggling SSL mode or changing port - Simplified restart: delete server (destructor cleanup) → create new server - Verified with 10+ rapid SSL toggles without crashes 2. HIGH: Fix SQL injection vulnerability in catalog search - Rewrite MySQL_Catalog::search() to use prepared statements - Use parameter binding (proxy_sqlite3_bind_text/bind_int) for user input - Escape single quotes in FTS5 MATCH clause (doesn't support parameters) - Tested against multiple injection attempts (single quote, backslash, comments, UNION SELECT, kind/tags parameter injection) - All 21 catalog tests still pass with new implementation 3. MEDIUM: Fix hardcoded user-specific path in config - Revert datadir from user-specific absolute path to /var/lib/proxysql - Ensures portability across different environments Testing: - SSL toggle: 7 tests passed (HTTP↔HTTPS, port changes, stress test) - SQL injection: 10 tests passed (various injection attempts blocked) - Catalog functionality: 21 tests passed (FTS5, BM25 ranking, etc.) - Total: 38 tests passed, 0 failed Fixes issues identified in GitHub PR #16 review.	3 months ago
Rahim Kanji	f7397f633c	Fix catalog search to use FTS5 and enhance test suite The catalog_fts FTS5 virtual table was being created but the search() function was using slow LIKE queries instead of FTS5 MATCH operator. Changes to lib/MySQL_Catalog.cpp: - Use FTS5 MATCH with INNER JOIN to catalog_fts when query provided - Add BM25 relevance ranking (ORDER BY bm25(f) ASC) - Significant performance improvement: O(log n) vs O(n) Changes to scripts/mcp/test_catalog.sh: - Add 8 new FTS5-specific tests (CAT013-CAT020): - Multi-term search (AND logic) - Phrase search with quotes - Boolean operators (OR, NOT) - Prefix search with wildcards - Kind and tags filter combinations - Relevance ranking verification - Add SSL/HTTP support with auto-detection - New options: --ssl, --no-ssl, MCP_USE_SSL env var - Fix endpoint path: /query -> /mcp/querywq	3 months ago
Rene Cannao	f449c4236f	fix: Improve question learning fallback and error logging Two bug fixes for the question learning feature: 1. Fallback to most recent agent_run across all schemas - get_last_agent_run_id() now falls back to the most recent agent_run_id across ALL runs if none exists for the specific run_id - This allows adding questions even when the current schema's discovery didn't include an agent run - Adds logging to show when fallback is used 2. Fix error message extraction for query_tool_calls logging - Fixed bug where error messages weren't being extracted correctly - The old code checked for result["error"]["message"] but create_error_response only has result["error"] (no nested "message" field) - Now correctly extracts result["error"] as a string when present - This ensures failed tool calls are properly logged with error messages This fixes the issue where llm.question_template_add would fail with "No agent run found" even when agent runs exist for other schemas.	3 months ago
Rene Cannao	5b502c0864	feat: Add question learning capability to demo agent Add ability for the demo agent to learn new questions and add them to the catalog, making it smarter over time. Changes: - Added get_last_agent_run_id() function to Discovery_Schema: - Queries agent_runs table for the most recent agent_run_id for a run_id - Returns 0 if no agent runs exist for the schema - Updated llm.question_template_add handler: - Made agent_run_id optional (defaults to 0 when not provided) - When agent_run_id <= 0, auto-fetches last agent_run_id for the schema - Returns helpful error if no agent run exists for the schema - Returns agent_run_id in response for visibility - Updated llm.question_template_add tool schema: - Moved agent_run_id from required to optional parameters - Updated description to explain auto-fetch behavior - Updated demo_agent_claude.sh prompt: - Added llm.question_template_add to available tools - Added Step 4: "Learn from Success" to workflow - Added explicit instruction to ALWAYS LEARN new questions - Added example showing learning workflow - Expanded from 4 steps to 5 steps to include learning Now the demo agent can: 1. Search for existing questions 2. Reuse SQL if a good match exists 3. Generate new SQL if no good match 4. LEARN new questions by adding them to the catalog 5. Present results This enables continuous learning - the more users interact with it, the smarter it becomes.	3 months ago
Rene Cannao	ee74384c79	fix: Prevent llm.search from returning huge object lists in list mode When llm.search is called with an empty query (list mode) to retrieve all available questions, include_objects=true was returning full object schemas for all related objects, resulting in massive responses that could fill the LLM's context and cause rejections. Fix: include_objects now only works when query is non-empty (search mode). When query is empty (list mode), only question templates are returned without object details, regardless of include_objects setting. This makes semantic sense: - Empty query = "list all questions" → just titles/bodies (compact) - Non-empty query = "search for specific questions" → full details including object schemas (for answering the question) Changes: - Modified fts_search_llm() to check !query.empty() before fetching objects - Updated tool schema description to clarify this behavior	3 months ago
Rene Cannao	7e522aa2c0	feat: Add schema parameter to run_sql_readonly with per-connection tracking Add optional schema parameter to run_sql_readonly tool that allows queries to be executed against a specific schema, independent of the default schema configured in mcp-mysql_schema. Changes: - Added current_schema field to MySQLConnection structure to track the currently selected schema for each connection in the pool - Added find_connection() helper to find connection wrapper by mysql pointer - Added execute_query_with_schema() function that: - Uses mysql_select_db() instead of 'USE schema' SQL statement - Only calls mysql_select_db() if the requested schema differs from the current schema (optimization to avoid unnecessary switches) - Updates current_schema after successful schema switch - Updated run_sql_readonly handler: - Extracts optional 'schema' parameter - Calls execute_query_with_schema() instead of execute_query() - Returns error response when query fails (instead of success) - Updated tool schema to document the new 'schema' parameter This fixes the issue where queries would run against the default schema (configured in mcp-mysql_schema) instead of the schema being queried, causing "Table doesn't exist" errors when the default schema differs from the discovered schema.	3 months ago
Rene Cannao	ee13e4bf13	feat: Add include_objects parameter to llm_search for complete object retrieval Enhance the llm_search MCP tool to return complete question template data and optionally include full object schemas, reducing the need for additional MCP calls when answering questions. Changes: - Added related_objects column to llm_question_templates table - Updated add_question_template() to accept and store related_objects JSON array - Enhanced fts_search_llm() with include_objects parameter: - LEFT JOIN with llm_question_templates to return example_sql, related_objects, template_json, and confidence - When include_objects=true, fetches full object schemas (columns, indexes) for all related objects in a single batch operation - Added error checking for SQL execution failures - Fixed fts_search_llm() get_object() call to pass schema_name and object_name separately instead of combined object_key - Updated Query_Tool_Handler: - Added is_boolean() handling to json_int() helper to properly convert JSON boolean true/false to int 1/0 - Updated llm.search handler to extract and pass include_objects parameter - Updated llm.question_template_add to extract and pass related_objects - Updated tool schemas to document new parameters This change allows agents to get all necessary schema information in a single llm_search call instead of making multiple catalog_get_object calls, significantly reducing MCP call overhead.	3 months ago
Rene Cannao	1b42cfbd27	feat: Add empty query support to llm_search for listing all artifacts Changes: - fts_search_llm(): Empty query now returns all artifacts (list mode) - Update llm.search tool: query parameter is now optional - Tool description mentions empty query lists all artifacts - Add body field to llm_search results - Update demo script: Add special case for "What questions can I ask?" This enables agents to retrieve all pre-defined question templates when users ask what questions are available, instead of inferring questions from schema.	3 months ago
Rene Cannao	5668c86809	fix: Implement FTS indexing for LLM artifacts and fix reserved keyword issue - Rename llm_search_log column from \"limit\" to \"lmt\" to avoid SQL reserved keyword - Add FTS inserts to all LLM artifact upsert functions: - add_question_template(): index question templates for search - add_llm_note(): index notes for search - upsert_llm_summary(): index object summaries for search - upsert_llm_domain(): index domains for search - upsert_llm_metric(): index metrics for search - Remove content='' from fts_llm table to store content directly - Add <functional> header for std::hash usage This fixes the bug where llm_search always returned empty results because the FTS index was never populated.	3 months ago
Rene Cannao	2250b762a3	feat: Add query_tool_calls table to log MCP tool invocations Add query_tool_calls table to Discovery Schema to track all MCP tool invocations via the /mcp/query/ endpoint. Logs: - tool_name: Name of the tool that was called - schema: Schema name (nullable, empty if not applicable) - run_id: Run ID from discovery (nullable, 0 if not applicable) - start_time: Start monotonic time in microseconds - execution_time: Execution duration in microseconds - error: Error message (null if success) Modified files: - Discovery_Schema.cpp: Added table creation and log_query_tool_call function - Discovery_Schema.h: Added function declaration - Query_Tool_Handler.cpp: Added logging after each tool execution	3 months ago
Rene Cannao	8a395b9b47	style: Add spaces around commas in SQL CREATE TABLE statements Format column definitions in CREATE TABLE IF NOT EXISTS statements to have a space before and after each comma (e.g., " , "). This allows ProxySQL Admin to properly display multi-line table schemas. Modified files: - Discovery_Schema.cpp - MySQL_Catalog.cpp - AI_Features_Manager.cpp	3 months ago
Rene Cannao	7c93280174	fix: Escape SQL reserved keyword 'limit' in llm_search_log table The column name 'limit' conflicts with SQL reserved keyword. Escaped as "\"limit\"" to fix table creation.	3 months ago
Rene Cannao	77643859e3	feat: Add timing columns to stats_mcp_query_tools_counters Extend the stats_mcp_query_tools_counters table with timing statistics (first_seen, last_seen, sum_time, min_time, max_time) following the same pattern as stats_mysql_query_digest. All timing values are in microseconds using monotonic_time(). New schema: - tool VARCHAR - schema VARCHAR - count INT - first_seen INTEGER (microseconds) - last_seen INTEGER (microseconds) - sum_time INTEGER (microseconds - total execution time) - min_time INTEGER (microseconds - minimum execution time) - max_time INTEGER (microseconds - maximum execution time)	3 months ago
Rene Cannao	fb66af7c1b	feat: Expose MCP catalog database in ProxySQL Admin interface The MCP catalog database is now accessible as the 'mcp_catalog' schema from the ProxySQL Admin interface, enabling direct SQL queries against discovered schemas and LLM memories.	3 months ago
