René Cannaò	507a68db29	Variable mysql-monitor_replication_lag_count ... Renamed variable mysql-monitor_replication_lag_retries to mysql-monitor_replication_lag_count to match other variables naming convention. As it is a counter, it minimum value is changed to 1. Maximum value sets to 10. Use of thread storage variable mysql_thread___monitor_replication_lag_count instead of GloMTH->variables.monitor_replication_lag_retries to avoid dirty reads .	6 years ago
Javier Jaramago Fernández	a2727739e4	Added new variable 'mysql-monitor_replication_lag_retries' ... This new variable controls the number of retries that replication lag needs to exceed 'max_replication_lag' in order to set a server SHUNNED.	6 years ago
René Cannaò	848ddb2177	Added variable mysql-connect_timeout_client ... This also fix bug #1132	6 years ago
René Cannaò	33d8db02a6	Change the mapping logic for SESSION_TRACK_GTIDS ... Changing the mapping logic in SESSION_TRACK_GTIDS in frontend and backend connections. Up to now, frontend and backend `SESSION_TRACK_GTIDSs match. This is now changed: * backend connections are by default set to `mysql-default_session_track_gtids` * if `mysql-default_session_track_gtids=OFF` (the default) , `session_track_gtids` is not changed on backend * if the client asks for `session_track_gtids=OFF` , proxysql ignores it (it just acknowledge it) * if the client asks for `session_track_gtids=OWN_GTID` , proxysql will apply it * if the client asks for `session_track_gtids=ALL_GTIDS` , proxysql will switch to OWN_GTID and generate a warning * if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities This commit also deprecates function `MySQL_Session::handler_again___verify_backend__generic_variable()` ProxySQL is now also able to know when proxysql binlog reader is perhaps in use tracking all gtid_port in mysql_servers. This feature in future will be used to deprecate `mysql-default_session_track_gtids`	6 years ago
René Cannaò	4748c7d052	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	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.

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	6 years ago
