- Scheduler is either initialized at server start or never.
Starting & stopping is now suspending & resuming.
- The scheduler has clear OO interface
- Now all calls to the scheduler are synchronous
- GLOBAL event_scheduler uses thd::sys_var_tmp (see set_var.cc)
- External API is encapsulated into class Events
- Includes fixes for all comments of Kostja's review of 19.05.2005
Starting to merge into 5.1-release (5.1.10) and push
BitKeeper/etc/ignore:
Added libmysqld/event_scheduler.cc to the ignore list
libmysqld/Makefile.am:
executor -> scheduler
mysql-test/r/events.result:
update result
mysql-test/r/events_bugs.result:
update result
mysql-test/r/events_logs_tests.result:
update result
mysql-test/r/events_microsec.result:
update result
mysql-test/r/events_scheduling.result:
update result
mysql-test/r/events_stress.result:
update result
mysql-test/t/disabled.def:
enable these tests
mysql-test/t/events.test:
optimize the test a bit for speed, save some seconds runtime
remove FULL from SHOW EVENTS
mostly use I_S.EVENTS
mysql-test/t/events_bugs.test:
Skip irrelevant for the current design tests - all events are loaded
on server startup. Change in mysql.event will be visible on next server start.
Don't use numeric error codes.
mysql-test/t/events_logs_tests.test:
optimize the test a bit for speed
mysql-test/t/events_microsec.test:
Skip irrelevant for the current design tests - all events are loaded
on server startup. Change in mysql.event will be visible on next server start.
Don't use numeric error codes.
mysql-test/t/events_scheduling.test:
broader test
mysql-test/t/events_stress.test:
Rework the test to the new architecture of suspending/resuming.
Use less events, no need for thousands, hundreds is still ok.
sql/Makefile.am:
executor -> scheduler
sql/cmakelists.txt:
executor -> scheduler
sql/event.cc:
- remove todo comments
- remove unneded evex_queue abstraction functions
- move events_init() and events_shutdown() from event_executor.cc to here
- export db_create_event
- remove evex_load_and_compile_event, part of class Event_scheduler
- integrate the public interface found in event.h and used by sql_parse.cc
to use the new class Event_scheduler.
sql/event.h:
- add COND_finished so if one thread kills a running event it waits on this
- export callback event_timed_definer_equal, event_timed_identifier_equal(),
event_timed_name_equal and event_timed_db_equal()
to be used by Event_scheduler::drop_matching_events()
- cleanup event.h
- encapsulated all external interface into class Events
sql/event_executor.cc:
make it empty, will delete after that
sql/event_priv.h:
- more things in the private header
- remove event queue abstraction functions. tightly bind to QUEUE
- export privately db_drop_event, db_find_event, db_create_event()
- made change_security_context() and restore_security_context() free functions
sql/event_timed.cc:
- fix calculation of time when ENDS is set (STARTS is always set)
- during Event_timed::compile() set the right Security_ctx. Prevents a crash
during Event_scheduler::load_events_from_db()
- add Event_timed::kill_thread()
- implement event_timed_*_equal()
- made change_security_context() and restore_security_context() free functions.
- Comments cleanups
sql/lex.h:
new word scheduler for SHOW SCHEDULER STATUS (available only debug builds)
sql/log.cc:
move these from event_scheduler.cc
sql/mysql_priv.h:
refactor kill_one_thread
export sql_print_message_func and sql_print_message_handlers
sql/mysqld.cc:
In close_connections, called by kill_server() skip the main scheduler
thread and use events_shutdown() for shutting down the scheduler, in the same
manner it's done for RPL.
Add a new value to --event-scheduler :
0 <- No scheduler available
1 <- Start with scheduler enabled
2 <- Start with scheduler suspended
sql/repl_failsafe.cc:
refactor thd::system_thread to be an enum
sql/set_var.cc:
move sys_var_event_executor::update() to set_var.cc
executor -> scheduler
use thd::sys_var_tmp
sql/set_var.h:
executor -> scheduler
sql/share/errmsg.txt:
3 new error messages
sql/sql_class.cc:
refactor thd::system_thread to be an enum . more type-safety
sql/sql_class.h:
refactor thd::system_thread to be an enum . more type-safety
sql/sql_db.cc:
get the error from evex_drop_schema_events
sql/sql_error.h:
export warning_level_names
sql/sql_lex.h:
new command SHOW SCHEDULER STATUS, available only in debug build and
for debug purposes.
sql/sql_parse.cc:
refactor kill_one_thread() -> does the *dirty* work, and sql_kill
just the reporting.
add handler for SQLCOM_SHOW_SCHEDULER_STATUS
sql/sql_show.cc:
fix verbosity handling (this will be obsoleted anyway by the fix for 17394).
sql/sql_yacc.yy:
remove FULL from SHOW EVENTS
add SHOW SCHEDULER STATUS in debug builds
sql/table.cc:
Fix valgrind warning.
