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).	4 weeks ago
Rahim Kanji	e723082a1b	Refactored Query Processor Architecture ... - Introduced separate query processors for MySQL and PostgreSQL. - Removed unnecessary GTID logic from `PgSQL_Session`. - Added a command counter for PostgreSQL queries. - Refactored `Query_Processor` to serve as a base class containing core functionalities applicable to both MySQL and PostgreSQL. Changes: - Removed GTID-related code from `PgSQL_Logger` and `PgSQL_Session`: - bool with_gtid; - char gtid_buf[128]; - int gtid_hid; - Added new PostgreSQL-specific tables: - `pgsql_query_rules`, `pgsql_firewall_whitelist_rules`, `pgsql_query_rules_fast_routing` - `runtime_pgsql_query_rules`, `runtime_pgsql_firewall_whitelist_rules`, `runtime_pgsql_query_rules_fast_routing` - Added PostgreSQL-related variables: pgsql_thread___commands_stats pgsql_thread___query_digests pgsql_thread___query_digests_lowercase pgsql_thread___query_digests_no_digits pgsql_thread___query_digests_replace_null pgsql_thread___query_digests_normalize_digest_text pgsql_thread___query_digests_track_hostname pgsql_thread___query_digests_keep_comment pgsql_thread___query_digests_max_digest_length pgsql_thread___query_digests_max_query_length pgsql_thread___query_digests_grouping_limit pgsql_thread___query_digests_groups_grouping_limit pgsql_thread___enable_load_data_local_infile pgsql_thread___auditlog_filename pgsql_thread___auditlog_filesize pgsql_thread___eventslog_filename pgsql_thread___eventslog_filesize pgsql_thread___eventslog_default_log pgsql_thread___eventslog_format pgsql_thread___firewall_whitelist_errormsg pgsql_thread___firewall_whitelist_enabled pgsql_thread___query_processor_iterations pgsql_thread___query_processor_regex	2 years ago
