René Cannaò	c4fce91fc5	Change default value of mysql-session_idle_ms from 1000 to 1 ... Not only the default value is change from 1000 to 1 , but it also perform an upgrade from earlier release. If during bootstrap a value of 1000 is found, it is automatically changed to 1 and a warning is generated. This release also prevents the value 1000 to be a valid one during bootstrap. This means that it is still possible to set the value to 1000 and to have a running proxysql instance with value 1000 , but during bootstrap it will be switched to 1. If you really want to set mysql-session_idle_ms close to 1000 , it is recommended to set it to a closer value like 999 or 1001	5 years ago

René Cannaò	aaddb4e568	Port of #3001 to 2.1.0 , related to #3000 ... A client connection can use a backend connection with a session variable set by a different client	6 years ago
René Cannaò	fdff65daea	Implementation of max_transaction_idle_time ... Former max_transaction_time is now renamed to max_transaction_idle_time. mysql-max_transaction_idle_time defines the maximum time a transaction can stay idle. mysql-max_transaction_time defines the maximum time of a transaction since its start.	6 years ago
René Cannaò	b8161c7fc4	Allow compile on FreeBSD	6 years ago
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
Javier Jaramago Fernández	31f0b7c535	Fixed 'MySQL_Threads_Handler::listener_del' logic for SO_REUSEPORT ... `MySQL_Threads_Handler::listener_del` is not aware of `perthrsocks` array used in `MySQL_Threads_Handler::listener_add`, because of this, isn't able to properly track which descriptors are being used in each thread. This patch makes the threads themselves responsible for closing the descriptors that they are using for listeners.	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	d9a85dfc7a	Input validation for mysql-default_session_track_gtids ... default_session_track_gtids allows only two values: OFF or OWN_GTID	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
