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

René Cannaò	aaf83eec78	Finalizing the support for more session variables ... Initial support for `SET SESSION TRANSACTION READ ONLY` or `READ WRITE`. Extended `SET` parser to support also `SET SESSION TRANSACTION`. Hostgroup Manager doesn't kill backend connections in case of error 1231. `autocommit` is set at session level but also on MySQL client connection. Added several debugging entries. Several `handler_again___verify_backend_*` functions are disabled if `locked_on_hostgroup` is enabled.	7 years ago

Brice Figureau	fccef7f64e	Parse multiple variable (simple) SET commands ... The current parser for SET in MySQL_Session is not able to parse multiple variables SET commands like: SET sql_mode='TRADITIONAL', NAMES utf8 COLLATE unicode_ci This patch introduces a simple regex based parser for all variation of simple variables. This is not a generic SET parser, though.	8 years ago
