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	20d6282a60	build(clean): ignore and remove generated MySQL parser artifacts Context: - Bison/Flex-generated parser files in `lib/` can be created locally during parser work. - These files are generated artifacts and should not be tracked. Changes: - Add generated parser artifacts to `.gitignore`: - `lib/MySQL_Lexer.yy.c` - `lib/MySQL_Parser.output` - `lib/MySQL_Parser.tab.c` - `lib/MySQL_Parser.tab.h` - Extend `lib/Makefile` `clean` target to remove the same generated files. Why: - Prevent accidental inclusion of regenerated parser outputs in feature commits. - Keep worktrees clean and make `make clean` deterministic for parser-related changes.	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
vramesha	15a4ed66e9	Optimize query logging performance (#5243 ) Detailed Changes: - Introduced LogBuffer and LogBufferThreadContext to implement per-thread buffering, reducing lock contention. - Replaced localtime() with localtime_r() for improved performance and thread safety during timestamp generation. - Implemented configurable sampling for event logs to reduce I/O overhead. - Added global configuration variables to control flush size, flush interval, and sampling rate for event and audit logs.	2 months ago
