René Cannaò	f4f0b2892e	Disable multiplexing for connections to Admin #466	10 years ago
René Cannaò	a7353d0c47	Support Admin module as a MySQL backend #466 ... The follow states are disabled in Admin module is the backend: - CHANGING_USER_SERVER - CHANGING_SCHEMA - CHANGING_CHARSET - CHANGING_AUTOCOMMIT - mysql-monitor_username is always added as a possible user : this allows MySQL_Monitor to monitor the backends - admin-admin_credentials and admin-stats_credentials are always added as possible users - mysql-monitor_username , admin-admin_credentials and stats-admin_credentials do not shows in mysql_users table (by design) - the above users have a max_connections limit of 1000 (hardcoded)	10 years ago

Summary: removed KV_Btree_Array.cpp removed query_SQL from MySQL_Data_Stream added some documentation for QC_entry_t Query_Cache::get() and Query_Cache::set() now requires also the length of the key Query_Cache::get() and Query_Cache::set() now process hk (the hash key) using the length of the key Query Cache enhancement on user/schema Query Cache now supports distinct entries based on user/schema . This is achieved passing to Query_Cache::set() and Query_Cache::get() the hash that identifies user and schema Test Plan: None Reviewers: rene Differential Revision: http://phab.sysown.com/D3	10 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
