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	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	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	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	4c788dcbb3	fix: signed/unsigned comparison warnings (-Wsign-compare) Fix two HIGH priority signed/unsigned comparison warnings: 1. MySQL_HostGroups_Manager.cpp:1792 - Change loop variable from 'int j' to 'unsigned int j' to match the unsigned comparison with servers->len. 2. MySQL_Thread.cpp:4357 - Cast int to size_t when comparing with getBufferSize() which returns size_t. These changes prevent potential logic errors from negative values being interpreted as large unsigned values. Found during compiler warning analysis with 'make debug'.	2 months ago

Rene Cannao	366164ab26	Fix #5272 : Add mysql-select_version_forwarding variable for SELECT VERSION() Since ProxySQL 3.0.4, SELECT VERSION() queries were intercepted and returned ProxySQL's mysql-server_version variable instead of proxying to backends. This broke SQLAlchemy for MariaDB which expects "MariaDB" in the version string. This commit adds a new variable `mysql-select_version_forwarding` with 4 modes: - 0 = never: Always return ProxySQL's version (3.0.4+ behavior) - 1 = always: Always proxy to backend (3.0.3 behavior) - 2 = smart (fallback to 0): Try backend connection, else ProxySQL version - 3 = smart (fallback to 1): Try backend connection, else proxy (default) The implementation includes: - New global variable mysql_thread___select_version_forwarding - New function get_backend_version_for_hostgroup() to peek at backend connection versions without removing them from the pool - Modified SELECT VERSION() handler to support all 4 modes - ProxySQL backend detection to avoid recursion Mode 3 (default) ensures SQLAlchemy always gets the real MariaDB version string while maintaining fast response when connections are available.	3 months ago
Javier Jaramago Fernández	6fea828e86	Improve logging in unexpected COM_PING packet handling Logging messages now include 'client address', 'session status' and 'data stream status'. Client address is also logged when OK packets are dispatched, this should help tracking if a client has received the expected packets or not.	4 months ago
Javier Jaramago Fernández	d0e88599ee	Add special handling for unexpected COM_PING packets Implements a workaround for the handling of unexpected 'COM_PING' packets received during query processing, while a resultset is yet being streamed to the client. Received 'COM_PING' packets are queued in the form of a counter. This counter is later used to sent the corresponding number of 'OK' packets to the client after 'MySQL_Session' has finished processing the current query.	4 months ago
Rene Cannao	5a7b22181f	Fix metrics collection for wait_timeout counters The get_status_variable() function was only scanning worker threads but ignoring auxiliary threads (idle threads) where timeout terminations are detected. This caused the timeout termination counter to show incorrect/zero values. - Added idle thread scanning to both overloaded versions of get_status_variable() function - Now properly collects metrics from both worker and idle threads - Fixes the issue where proxysql_mysql_timeout_terminated_connections_total showed zero despite actual timeout terminations Resolves the metrics reading issue identified in the previous commits.	4 months ago
Rene Cannao	dc4694d656	Refactor idle session scanning and improve test precision Code improvements: - Extract SESS_TO_SCAN_idle_thread constant to header file for better maintainability - Replace magic number 128 with named constant in idle_thread_to_kill_idle_sessions() - Improve code readability and consistency in session scanning logic Test enhancements: - Add mysql-poll_timeout configuration for more precise timeout testing - Reduce test sleep times to 13 seconds for faster test execution - Add diagnostic messages to clearly show timeout configurations in test output - Ensure tests properly validate timeout enforcement with precise timing The changes improve code maintainability and make tests more reliable and faster while maintaining accurate timeout validation.	4 months ago
Rene Cannao	0c5e75a064	Fix wait_timeout timeout calculations and add proper newline characters Key improvements: - Fix timeout comparison in MySQL_Thread::idle_thread_to_kill_idle_sessions() to prevent underflow - Use effective wait_timeout (minimum of global and session values) for idle timeout calculations - Add proper newline characters to proxy_warning messages for consistent log formatting - Increase test sleep times to account for global timeout enforcement - Fix session timeout test durations to properly test timeout behavior Technical changes: - Replace broken min_idle calculation with proper effective wait_timeout logic - Add std::min() usage to determine effective timeout from global and session values - Ensure warning messages end with newline characters for proper log formatting - Update test sleep durations to ensure proper timeout testing Resolves potential timeout calculation bugs and ensures consistent timeout enforcement behavior.	4 months ago

Rene Cannao	44aa606caa	Implement fast forward grace close feature to prevent data loss Problem: In fast forward mode, ProxySQL forwards packets directly from client to backend without buffering them. If the backend connection closes unexpectedly (e.g., due to server crash, network failure, or other issues), ProxySQL immediately closes the client session. This can result in data loss because the client may have sent additional data that hasn't been fully transmitted yet, as ProxySQL does not wait for the output buffers to drain. Solution: Implement a configurable grace period for session closure in fast forward mode. When the backend closes unexpectedly, instead of closing the session immediately, ProxySQL waits for a configurable timeout (fast_forward_grace_close_ms, default 5000ms) to allow any pending client output data to be sent. During this grace period: - If the client output buffers become empty, the session closes gracefully. - If the timeout expires, the session closes anyway to prevent indefinite hanging. Changes: - Added global variable mysql_thread___fast_forward_grace_close_ms (0-3600000ms) - Added session flags: backend_closed_in_fast_forward, fast_forward_grace_start_time - Added data stream flag: defer_close_due_to_fast_forward - Modified MySQL_Data_Stream::read_from_net() to detect backend EOF and initiate grace close if client buffers are not empty - Modified MySQL_Session::handler() FAST_FORWARD case to implement grace close logic with timeout and buffer checks - Added extensive inline documentation explaining the feature and its mechanics This prevents data loss in fast forward scenarios while maintaining bounded session lifetime.	5 months ago
