René Cannaò	bf4c7578e9	Various bug fixes related to deprecated mysql-default_ variables ... Extended `mysql_variable_st` to add a new variable `is_global_variable`. Using this variable we define the global variables. Modified `mysql_tracked_variables[]` to also specify `is_global_variable`. Removed `default_charset` from `MySQL_Threads_Handler::variables` to use `mysql_tracked_variables[]` instead. Removed `default_charset` also from `mysql_thread_variables_names[]`. Fixed `MySQL_Threads_Handler::get_variable_string()` : it was *not* returning `mysql-default_` variables. `MySQL_Threads_Handler::set_variable()` adds `mysql-default_` variables only if `is_global_variable` is set. In `MySQL_Threads_Handler::set_variable()` replaced a `strcasecmp()` with `strcmp()` for `mysql-default_` variables. `MySQL_Threads_Handler::get_variables_list()` returns only `mysql-default_` variables with `is_global_variable` enabled. `MySQL_Threads_Handler::has_variable()` for `mysql-default_` variables returns true only if variable has `is_global_variable` enabled. `MySQL_Thread::refresh_variables()` does not refresh `mysql-default_` variables if `is_global_variable` is not enabled. `MySQL_Thread::MySQL_Thread()` initializes to NULL all `mysql_thread___default_variables[]` variables. Completely disabled in `ProxySQL_Admin::flush_mysql_variables___database_to_runtime()` the logic applied to all charset variables. In the same methos was implemented the logic described in #1785 : `mysql-default_charset` and `mysql-default_collation_connection` must be compatible: * if only one is present, the other is configured automatically * if not compatible, `mysql-default_charset` is configured from `mysql-default_collation_connection`	6 years ago

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

René Cannaò	485d313514	Further development of firewall whitelist. ... * introduced 2 new variables: - mysql-firewall_whitelist_enabled : defines if the firewall with whitelist algorithm is enabled or not - firewall_whitelist_errormsg : error message returned to the client if an error message is not already set * Query_Processor returns firewall_whitelist_mode to the calling MySQL_Session, but the logging on error log currently happens within the Query_Processor itself * if mysql-firewall_whitelist_enabled is turned on and a user it is not found in mysql_firewall_whitelist_users , the default behavior is that query is rejected * lookup on mysql_firewall_whitelist_users happens for username@ip (specific IP) and username@'' (all IPs) . Match on network subnet is currently not implemented * implemented SAVE MYSQL FIREWALL FROM RUNTIME * fixed implementation of SAVE MYSQL FIREWALL TO DISK * runtime configuration can be viewed in runtime_mysql_firewall_whitelist_rules and runtime_mysql_firewall_whitelist_users	7 years ago
