SHOW STATUS are not anymore put in slow query log because of no index usage.
Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command()
This simplifies code and allows us to remove some if statements all over the code.
Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands.
This allowed some overall simplifaction when testing sql_command.
Fixes bugs:
Bug#10210: running SHOW STATUS increments counters it shouldn't
Bug#19764: SHOW commands end up in the slow log as table scans
mysql-test/r/grant_cache.result:
Fixed results after SHOW STATUS doesn't anymore affect status variables
mysql-test/r/information_schema.result:
Added extra test to cover more code
mysql-test/r/query_cache.result:
Remove resuts from previous tests
mysql-test/r/status.result:
Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables.
(Bug#10210)
mysql-test/r/temp_table.result:
Fixed results after SHOW STATUS doesn't anymore affect status variables
mysql-test/r/union.result:
Fixed results after SHOW STATUS is not logged to slow query log
(Bug#19764)
mysql-test/t/events_microsec.test:
Disable warnings at init
mysql-test/t/information_schema.test:
Added extra test to cover more code
mysql-test/t/query_cache.test:
Remove resuts from previous tests
mysql-test/t/status.test:
Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables.
(Bug #10210)
sql/mysql_priv.h:
Added 'sql_command_flags'
sql/sql_class.cc:
New function add_diff_to_status(), used to update global status variables when using SHOW STATUS
sql/sql_class.h:
New function 'fill_information_schema_tables()'
(One could not anymore use fill_derived_tables() for this as only_view_structures() is not relevant for information schema tables)
Added defines for bit flags in sql_command_flags[]
sql/sql_lex.cc:
Remove orig_sql_command
sql/sql_lex.h:
Remove orig_sql_command
sql/sql_parse.cc:
Rename uc_update_queries -> sql_command_flags.
Enhanced 'sql_command_flags' to better classify SQL commands
uc_update_queries[] != 0 is changed to (sql_command_flags[] & CF_CHANGES_DATA)
lex->orig_sql_command == SQLCOM_END is changed to (sql_command_flags[lex->sql_command] & CF_STATUS_COMMAND) == 0)
Simplify incrementing of thd->status_var.com_stat[] as we don't have to do special handling for SHOW commands.
Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function.
Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling.
These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command.
Don't log SHOW STATUS commands to slow query log.
This fixes Bug#10210 and Bug#19764 without adding additional 'if' code.
(The new code is faster than the original as we now have fewer if's than before)
sql/sql_prepare.cc:
Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[]
This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement.
sql/sql_select.cc:
Remove special handling of SHOW STATUS.
(This is now done in SQLCOM_SHOW_STATUS part in mysql_execute_command())
sql/sql_show.cc:
Remove orig_sql_command
Only change sql_command during 'open_normal_and_derived_tables()' (for views) and not for the full duration of generating data.
Changed 'show status' to use thd->initial_status_var to ensure that the current statement is not affecting the to-be-used values.
Use thd->fill_information_schema_tables() instead of 'thd->fill_derived_tables()' as the later wrongly checks the value of sql_command.
sql/sql_yacc.yy:
Remove usage of orig_sql_command.
One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command.
sql/structs.h:
Updated comment
- 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

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_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:

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

0 <- No scheduler available
1 <- Start with scheduler enabled
2 <- Start with scheduler suspended
