Valentin Rakush	796ea5b215	Character set handling implementation	6 years ago
René Cannaò	d242771a25	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	e9dc7a9b60	Implementation of SQLI fingerprints whitelist ... libsqlinjection generates a lot of false positives. This commit introduces a new table: mysql_firewall_whitelist_sqli_fingerprints This table can list fingerprints generated by libsqlinjection: if the fingerprint is listed in this table, proxysql will consider it as a false positive.
