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
