Author	SHA1	Message	Date
René Cannaò	d963232ce0	Ignore tracking of session_track_system_variables ... Adding variable session_track_system_variables to `ignore_vars` Also added `@@session.` and `@@global.` in the parser for SET statements (parse1v2) See issue #4839	12 months ago
Javier Jaramago Fernández	f260e2ee9f	Fix 'mysqld_error.h' include using deps path	2 years ago
Javier Jaramago Fernández	b91b6b8f9f	Add list of special permitted variables tracking errors - Closes #4591 ... This list hold tracking errors that in practice are equivalent to ER_UNKNOWN_SYSTEM_VARIABLE and that we want to handle in the same way.	2 years ago
René Cannaò	699fe7efcd	Moved proxysql_find_charset_* functions out of MySQL_Thread.cpp	2 years ago
Rahim Kanji	a3d29863e8	Adding SET TRANSACTION ISOLATION LEVEL * support	3 years ago

René Cannaò	c0fdf02b78	Fixed various compiler warnings	4 years ago
René Cannaò	d20683c589	Merge pull request #3702 from sysown/v2.x-variables ... Improvements on how MySQL variables are processed	4 years ago
René Cannaò	ba929e2851	Improved handling of sql_big_selects variable	4 years ago
René Cannaò	e983fc6827	Adding support for more MySQL variables ... New variables supported: - lc_messages - lc_time_names - long_query_time - max_execution_time - max_heap_table_size - max_sort_length - optimizer_prune_level - optimizer_search_depth - optimizer_switch - sort_buffer_size - sql_big_selects - timestamp - tmp_table_size Note: sql_big_selects is still not fully supported when combined with max_join_size. In set testing TAP ,set large max_execution_time. If max_execution_time is too small, the TAP test may fails because the queries will timeout.	4 years ago
René Cannaò	9ee636395d	Remove poor optimization to disable wsrep_sync_wait #3723 ... Fix inappropriate optimization in detecting backend version and handling of wsrep_sync_wait	4 years ago
René Cannaò	2ba9c401f1	Bug fixes in the new implementation of tracking mysql variables ... Better parsing of SET SQL_LOG_BIN . SQL_LOG_BIN is now managed by the same functions that handle boolean variables instead of the now deprecated MySQL_Session::handler_WCD_SS_MCQ_qpo_Parse_SQL_LOG_BIN() For naming convention, enum value SQL_LOG_BIN was renamed to SQL_SQL_LOG_BIN In MySQL_Thread we also deprecated match_regexes[0] , previously used to parse `set sql_log_bin`. Functions Variable::fill_server_internal_session() and Variable::fill_client_internal_session() seems to handle sql_log_bin as a special value. This exception was removed. Fixed a bug in MySQL_Session::generate_proxysql_internal_session_json() where when backend variables needed to be generated, fill_client_internal_session() was incorrectly called instead of fill_server_internal_session() , leading to incorrect values reported by `PROXYSQL INTERNAL SESSION`	4 years ago
René Cannaò	497ef76478	Merge branch 'v2.x' into v2.x-variables	4 years ago
René Cannaò	d335bfb899	Improvements on how MySQL variables are processed ... Deprecated variables: - net_write_timeout Renamed set_testing-t.csv to set_testing-t.csv.obsolete , and removed net_write_timeout from set_testing-t.csv Variables added to ignore list: - net_write_timeout - net_buffer_length - read_buffer_size - read_rnd_buffer_size Added support for quoting with backtick Renamed `enum variable_name` into `enum mysql_variable_name` for better readibility `enum mysql_variable_name` has variable names alphabetically ordered after SQL_NAME_LAST_LOW_WM `mysql_tracked_variables` has variable names alphabetically ordered after SQL_NAME_LAST_LOW_WM A lot of new variables added in `mysql_tracked_variables` , although not all tracked yet (TODO) In `MySQL_Variables::MySQL_Variables()`: - if `internal_variable_name` in `mysql_tracked_variables` is NULL , it will be automatically initialized - it performs some sanity check between `enum mysql_variable_name` and `mysql_tracked_variables` Testing: - refactored code in set_testing-t.cpp and set_testing-multi-t.cpp - added set_testing-240-t.cpp to test improvements in 2.4.0 - generate_set_session_csv to automatically create set_testing-240.csv used by set_testing-240-t	4 years ago

In handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY_qpo() Changing the default of exit_after_SetParse from false to true.

René Cannaò	c28deb7c7d	Generalize the use of session variables ... Added new array mysql_tracked_variables[] that defines the tracked variables. Ideally, tracking a new session variable will requires adding only a couple of lines of code. Removed session variables from mysql_thread_variables_names: - now both MySQL_Threads_Handler::get_variables_list() and MySQL_Threads_Handler::has_variable() rely on mysql_tracked_variables[] Simplified MySQL_Variables, as it now also uses mysql_tracked_variables[] . Simplify parser in MySQL_Session Generalized code to handle two variables together: - sql_auto_is_null - sql_safe_updates Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size Migrating more session variables to new algorithm - collation_connection - net_write_timeout - max_join_size	6 years ago
