MDEV 4427: query timeouts
Added MAX_STATEMENT_TIME user variable to automaticly kill queries after a given time limit has expired. - Added timer functions based on pthread_cond_timedwait - Added kill_handlerton() to signal storage engines about kill/timeout - Added support for GRANT ... MAX_STATEMENT_TIME=# - Copy max_statement_time to current user, if stored in mysql.user - Added status variable max_statement_time_exceeded - Added KILL_TIMEOUT - Removed digest hash from performance schema tests as they change all the time. - Updated test results that changed because of the new user variables or new fields in mysql.user This functionallity is inspired by work done by Davi Arnaut at twitter. Test case is copied from Davi's work. Documentation can be found at https://kb.askmonty.org/en/how-to-limittimeout-queries/ mysql-test/r/mysqld--help.result: Updated for new help message mysql-test/suite/perfschema/r/all_instances.result: Added new mutex mysql-test/suite/sys_vars/r/max_statement_time_basic.result: Added testing of max_statement_time mysql-test/suite/sys_vars/t/max_statement_time_basic.test: Added testing of max_statement_time mysql-test/t/max_statement_time.test: Added testing of max_statement_time mysys/CMakeLists.txt: Added thr_timer mysys/my_init.c: mysys/mysys_priv.h: Added new mutex and condition variables Added new mutex and condition variables mysys/thr_timer.c: Added timer functions based on pthread_cond_timedwait() This can be compiled with HAVE_TIMER_CREATE to benchmark agains timer_create()/timer_settime() sql/lex.h: Added MAX_STATEMENT_TIME sql/log_event.cc: Safety fix (timeout should be threated as an interrupted query) sql/mysqld.cc: Added support for timers Added status variable max_statement_time_exceeded sql/share/errmsg-utf8.txt: Added ER_QUERY_TIMEOUT sql/signal_handler.cc: Added support for KILL_TIMEOUT sql/sql_acl.cc: Added support for GRANT ...
