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	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
Javier Jaramago Fernández	1f47834306	Added conditional 'grave accents' outside capturing group to 'VAR_P1' regex matching variable name #3479	5 years ago
Javier Jaramago Fernández	a0020a43f2	Improved 'VAR_VALUE_P1' regex for 'SetParser::parse1' fixing several issues ... 1. Introduced extra paranethesis at the beggining and end of the regex for maching queries surrounded by them like: `( SELECT ... )`. 2. Added explicit SELECT at the beggining to mach queries starting with `SELECT`. 2. Introduced a new 'OR' in the first part of the regex: `|(?:NULL)` in order to avoid collapsing NULL values followed by commas without spaces. 3. Improved final section of the regex `(?:)` that was previously macthing with multiple empty groups, inducing a complete collapse of the initial query into an empty value in case of not matching the initial capturing group. With the new one, in case of emtpy value the external parenthesis are matched, for being remove later from the value.	5 years ago
