Developed class StatCounters to keep time series counters Added 2 new instances of StatCounters: - MySQL_Session::command_counters; - ProxySQL_Poll::loop_counters; Counters are dispayed in "dbg thread status" Defined new variables mysql-connect_timeout_server_error and mysql-connect_timeout_server (issue #202 and #203) . They are defined but not implemented yet. Fixed two crashing bug when "gdb command" was trying to access: - its own Query_Info if this one was not initialized - Query_Info of another thread if this one was not initialized Introduced new variable ProxySQL_Poll:poll_timeout that Session can overwrite to apply a timeout different than mysql_thread___poll_timeout Added variable MySQL_Connection::last_time_used , updated at creation time and when calling push_MyConn_to_pool(). for each Connection add a "last_time_used" Added function get_multiple_idle_connections() Implementing Standard_MySQL_Threads_Handler::connection_manager_thread() , but doesn't seems to be a good idea ==== New attempt for connection handling MySQL_Session has a new bool variable : connections_handler Standard_MySQL_Thread has a new variable PtrArray : mysql_sessions_connections_handler Added new function Standard_MySQL_Thread::register_session_connection_handler SESSIONS_FOR_CONNECTIONS_HANDLER sessions are created in Standard_MySQL_Thread::init() Added new function Standard_MySQL_Thread::process_all_sessions_connections_handler() New variables in Standard_MySQL_Thread: MySQL_Connection **my_idle_conns; bool processing_idles; unsigned long long last_processing_idles; Added DSS STATE_PING_SENT MySQL_Session::handler___status_WAITING_SERVER_DATA___STATE_PING_SENT	11 years ago
