René Cannaò	a6c53d0d12	Revert "Refactor header includes."	9 years ago
Maxim Bublis	30dbcc21a8	Refactor header includes. * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	10 years ago

Introduced also a parser for escaping strings with single quotes: double quotes are allowed without extra escaping	10 years ago

René Cannaò	31ac6625f6	Logging improvements, related to #561 - added new function realtime_time() to get real time - added support for multiple events, default PROXYSQL_QUERY - MySQL_Event::write() will perfom a different action depending from log_event_type - rewrote part of eventslog_reader_sample.cpp: - it had few bugs - MySQL_Event::read() will perform a different action depending from log_event_type - time are printed in real time and not monotonic time - all info about a query are printed in one line	10 years ago

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	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	c7fc81fa4b	Solved issue #43	12 years ago
René Cannaò	ee34919f9f	Issues #19 and #23 For issue #19: - create MySQL_Protocol::get_myds() - create MySQL_Protocol::generate_pkt_row() - modified MySQL_Session::(admin_func)(MySQL_Session ) to MySQL_Session::(admin_func)(MySQL_Session ,ProxySQL_Admin ,PtrSize_t ) so it can access more data - fixed an invalid strdup in SQLite3_row::add_fields() - added SQLite3_result::rows_count - SQLite3DB instances in Standard_ProxySQL_Admin are now public - create Standard_ProxySQL_Admin::SQLite3_to_MySQL() For issue #23 : - added __dump_pkt() in mysql_data_stream.cpp Bug fix: Added a missing pthread_mutex_unlock() in Admin/child_mysql() Minor clean-ups	12 years ago
René Cannaò	de7803370f	Fixed issue #2 Improved performance in MySQL_Data_Stream::array2buffer() Optimized class PtrSizeArray	12 years ago
