René Cannaò	625c969a5d	Use hash password in mysql_users This feature is not completed yet. libmariadb/password.c is patched to use either password or sha1(password) Class MySQL_Connection_userinfo() is expanded to also support sha1_pass Inroduced MySQL_Authentication::set_SHA1() to store this information at runtime only Added several auxiliary functions	10 years ago
René Cannaò	8b04641823	When connections are initialized, queries in mysql-init_connect are executed This allows to set custom variables like 'wait_timeout' or 'sort_buffer_size', or others. Issue #590. Closes #590	10 years ago

René Cannaò	f40affc361	Removed variable mysql-bug_mdev_8338 It seems that bug https://mariadb.atlassian.net/browse/MDEV-8338 is so severe that bypassing it from ProxySQL is not that easy. If affected by https://mariadb.atlassian.net/browse/MDEV-8338 , a user should disable mysql-multiplexing	10 years ago

René Cannaò	d0cabf1a9e	Better handling of bug MDEV-8338 Related to bug https://mariadb.atlassian.net/browse/MDEV-8338 . Created new variable: mysql-bug_mdev_8338 If this variable is set, multiplexing is disabled if a query has NOW() or CURDATE()	10 years ago

René Cannaò	3449ab0f59	Track and handle autocommit (#438 ) - implement new state CHANGING_AUTOCOMMIT - use mysql_autocommit_start() and mysql_autocommit_end()	11 years ago
René Cannaò	c3e6fda7a4	Track and handle autocommit (#438 ) - MySQL_Session::handler_special_queries() processes set autocommit from clients - to the client is always returned the autocommit value set in the session - set autocommit is either just acknowledged to the client, or forwarded to the backend based on the status of transactions - unless there are query rules to handle SET AUTOCOMMIT , the statement is forwarded to the first found active transaction: this assumes there is just one transactions. Although multiple transactions are possible, handling multiple transactions at the same time seems a dangerous adventure	11 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	9e6ce50739	Issue #28 , #29 and #30 in class MySQL_Connection_Pool: - shared converted from int to bool - added 2 functions MySQL_Connection_lookup() in class MyConnArray: - match() and add() are not private - class MySQL_Connection_Pool is a friend class - added function MyConn_find() in class MySQL_Connection: - class MyConnArray is a friend class - MCA is private - removed custom operator new() and delete() because MySQL_Connection_Pool can be shared - all members don't use the custom memory allocator - added private function is_expired .
