One can set @@global.max_user_connections to -1 to block anyone, except SUPER user, to login. If max_user_connection is 0, one can't change it without a restart (needed to get user connections counting to work correctly) mysql-test/r/system_mysql_db.result: Changed max_user_connections to handle negative numbers. mysql-test/r/user_limits-2.result: New test case that one can't change max_user_connection if it was 0 mysql-test/r/user_limits.result: Fixed wrong error messages. mysql-test/r/variables.result: Store / restore max_user_connections (needed as there is now a --master.opt file that changes it) mysql-test/t/subselect_mat_cost-master.opt: Enable slow query log (as this test found some errors in slow query logging) mysql-test/t/user_limits-2.test: New test case that one can't change max_user_connection if it was 0 mysql-test/t/user_limits-master.opt: Set max_user_connections (as one can't change it if it was 0) mysql-test/t/user_limits.test: Test max_user_connections -1 mysql-test/t/variables-master.opt: Set max_user_connections (as one can't change it if it was 0) mysql-test/t/variables.test: Set/restore max_user_connections scripts/Makefile.am: Add a text message to mysql_fix_privilege_tables.sql that it's automaticly generated scripts/mysql_system_tables.sql: Change max_user_connections to signed scripts/mysql_system_tables_fix.sql: Change max_user_connections to signed sql/item_func.cc: Change SHOW_INT to be signed. (Needed for max_user_connections and it's probably a bug that it was not originally signed) sql/log.cc: Remove some code that was not needed (All these variables are reset at start of query) sql/mysql_priv.h: Made max_user_connections signed. Added max_user_connections_checking sql/mysqld.cc: Added max_user_connections_checking so that we know if max_user_connections was 0 at startup (Which means that we will not do connection counting for accounts that don't have user resource limits) Set thd->start_utime at same time as thr_create_utime. (Before start_utime could be < thr_create_utime which lead to wrong query counting) sql/set_var.cc: Don't allow one to change 'max_user_connections' if it was 0 at startup. sql/sql_acl.cc: Change user_connection counting to be negative. sql/sql_connect.cc: If max_user_connections is < 0 then only SUPER user can login. Fixed wrong variable names for error messages. Fixed wrong initial value for questions. Set thd->start_utime and thd->thr_create_utime at startup. Needed to get time_out_user_resource_limits() to work. sql/sql_show.cc: SHOW_INT is now negative sql/sql_yacc.yy: Support negative values for MAX_USER_CONNECTIONS sql/structs.h: Make user connect counting work with signed numbers.
