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	24ab9f4398	More work for facilitate debug in MySQL Thread (issue #198 ) Standard_MySQL_Threads_Handler::SQL3_Threads_status() (still not completed) now locks the MySQL Threads Some functions of Standard_MySQL_Threads_Handler and Standard_MySQL_Thread are taken out from the class definition	11 years ago
René Cannaò	125114b0d5	Work for facilitate debug in MySQL Thread (issue #198 ) In order to facilitate the reuse of code in Standard_ProxySQL_Admin.cpp : - moved remove_spaces() from Standard_ProxySQL_Admin.cpp to gen_utils.cpp - moved Standard_ProxySQL_Admin::SQLite3_to_MySQL() to MySQL_Session::SQLite3_to_MySQL() Moved few macros from Standard_Query_Processor.cpp to proxysql_macros.h Added functions: - MySQL_Session::SQL3_Session_status() - MySQL_Session::handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY_debug() - Standard_MySQL_Thread::SQL3_Thread_status() - MySQL_Threads_Handler::SQL3_Threads_status() (not completed) Modified class Query_Info to copy queries : this can be a small performance penalty, but can improve functionalities Added mysql commands: - DBG SESSION STATUS - DBG THREAD STATUS - DBG THREADS STATUS Added variable MySQL_Thread::thread_mutex , a mutex to protect the thread: this will be used to implement access to MySQL Thread via Admin MySQL_Thread now have a new per thread variable updated via Admin Interface : - mysql_thread___session_debug ProxySQL_Poll now counts number of poll() in variable "loops" If mysql_thread___session_debug is enabled and a query starts with "dbg " it is interpreted as a command for proxysql. In Standard_ProxySQL_Admin added a variable admin_mutex to protect the update of statistics. Fixed minor bugs.	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
