René Cannaò	21b20c0257	Connection pool improvements , in beta 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

René Cannaò	13eb687335	More work on issue #168 Implemented new class Query_Info used in MySQL_Session Added MYSQL_COM_QUERY_command MYSQL_COM_QUERY_COMMIT Added virtual function Query_Processor::query_parser_update_counters() curtime moved from local variable in Standard_MySQL_Thread::run() to public variable in MySQL_Thread , so accessible by other classes Extended stats_mysql_commands_counters from 2 columns to 15 columns!! It nows have betters statistics on timing and distribution Added command MYSQL_COM_QUERY___NONE as a marker . It also have the special meaning that Query_Info is not a query. commands_counters is now an array of pointers to Command_Counter objects MySQL_Data_Stream::read_from_net() updates mypolls->last_recv[] with curtime if mypolls is active (MySQL_Thread) MySQL_Data_Stream::write_to_net() updates mypolls->last_sent[] with curtime if mypolls is active (MySQL_Thread) For MySQL queries (_MYSQL_COM_QUERY) queries statistics are updated via CurrentQuery, an instance of Query_Info	11 years ago
