Javier Jaramago Fernández	5c3a063775	Fix digest comment removal for queries over 'query_digests_max_query_length' Due to a typo/confusion, the boundary being used for comments check was 'd_max_len' instead of 'q_len'. This prevented the correct detection of a comment start when the query exceeded 'query_digests_max_query_length' which determines the value for 'd_max_len'.	10 months 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	1 year ago

René Cannaò	eb7a0e37f1	Moved legacy code away from c_tokenizer.cpp mysql_query_digest_and_first_comment() moved into c_tokenizer_legacy.cpp . c_tokenizer_legacy.cpp is present but not compiled, here for reference only.	2 years ago

Javier Jaramago Fernández	1b06049c41	Remove final query delimiter ';' from query digests Only the delimiter present at the end of the digest will be removed. Delimiters found in the middle of the full digest, like in the case of multi-statements should be preserved.	4 years ago

--global	44d6e48c7b	Fix conditional jumps based on uninitialized memory at 'process_cmnt_type_1' Solved previously left TODOs, removed faulty logic for whitespace processing for comments using position 'res_cur_pos'. This position shall not be used because points to yet uninitialized memory, last position with copied query data should always be 'res_cur_pos-1'. Because of it, removing the extra logic based on 'res_cur_pos' should be harmless.	4 years ago

--global	14fd17a491	Fix conditional jumps based on uninitialized memory at 'process_cmnt_type_1' Solved previously left TODOs, removing legacy code performing a filtering and addition of whitespaces while processing comments. This filtering or addition should be performed during 'stage_1_parsing' main processing loop if 'query_digests_keep_comment' is 'false' and within 'process_cmnt_type_1' otherwise.	4 years ago
