-												WL#3337 (Event scheduler new architecture)
This patch introduces specialized Event data objects
Event_basic as parent.
Event_queue_element used for queue storage
Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT
Event_job_data using during execution.
Methods were moved out of Event_timed to other classes.

This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().

Shortened a bit the runtime for executing events test cases.

  test for bug#17289 Events: missing privilege check for drop database
sql/event.h:
  -add two new methods to event_timed to change and restore
   the security context
sql/event_executor.cc:
  - move code regarding privilieges checking to event_timed::execute()
  - add a new function evex_print_warnings() which prints the notes/warnings/errors
    to the console (easily capturable with logs-into-tables) so one can see what
    has happened if there was an error of some sort!
sql/event_timed.cc:
  - fix documentation
  - add a new error code -99, EVENT was revoked from the user on the DB
  - set_sec_ctx, execute, restore_sex_ctx
sql/sql_error.cc:
  - make warning_level_names public to be used in event_executor.cc

-												fix for bug #17619 Scheduler race conditions
- 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

-												WL#3337 (Event scheduler new architecture)
This patch introduces specialized Event data objects
Event_basic as parent.
Event_queue_element used for queue storage
Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT
Event_job_data using during execution.
Methods were moved out of Event_timed to other classes.

This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().

Shortened a bit the runtime for executing events test cases.

- fix EVENT_ACL problem that GRANT ALL on some_db.* to someone@somewhere did not get to mysql.db
- fix crash when the following is executed :
  CREATE EVENT P() CREATE EVENT E ON SCHEDULER 1 SECOND DO ROLLBACK;
  (creation works as well as calling P() which creates the event).


mysql-test/lib/init_db.sql:
  - fix init_db.sql so add Event_priv to the database privs, many tests failed because of that
    ommision
  - remove the quotes from the column names
mysql-test/t/events.test:
  - fix the small test, don't create own db
scripts/mysql_fix_privilege_tables.sql:
  - fix that
sql/event.cc:
  - be defensive and don't crash if outside has already has opened some table
sql/event_executor.cc:
  - show in SHOW PROCESSLIST - "event_scheduler" as name of the user of the main thread
  - use "localhost" as the host where event_scheduler comes from
  - comment out some debug info, fix other debug info
sql/event_timed.cc:
  - enable EVENT creation inside SP. sphead from lex->sphead goes to et->sphead. it's there only
    if we compile the event. OTOH when doing 
    CREATE PROCEDURE PROC() CREATE EVENT SOME_EV ON SCHEDULE EVERY 1 SECOND DO ROLLBACK;
    I have only to get the body of the event which is anonymous SP. Before it being "compiled"
    but then freed without being used because a bit later it is compiled one more time before
    being put in the events cache. So it was good that the memory structures weren't reused but
    scrapped out. Now lex->sphead is not needed during event creation but only where the event's
    body starts and where it ends so to be able at later stage to compile this anonymous SP (the
    body of the event).
sql/sp_head.cc:
  - copy over a fix to a crash
sql/sql_acl.h:
  - fix privileges.
    There was _NO_ documentation about that. Another CHUNK had to be created to so EVENT_ACL gets shifted to
    it's place in the db table. So how this is calculated? EVENT_ACL is 1 << 26. Remember 26, see which poistion
    in the db table is EVENT_ACL, it's 17, counted from 0. 26 - 17 = 9, then shift it with 9.
    CHUNKS are created because in some cases some privileges are in chunks and they are shifted at once. There are
    few chunks of such privileges which has to be shifted to get to exactly the structure of mysql.db table.
sql/sql_parse.cc:
  - ok, we don't care anymore about lex->sphead because our sphead is lex->et->sphead
sql/sql_yacc.yy:
  - bail out if new event_timed returns 0x0
  - enable creation of an event inside a SP
    CREATE PROCEDURE P() CREATE EVENT E ON SCHEDULE EVERY 1 SECOND DO SELECT 1;

mysql-test/t/system_mysql_db_fix.test:
  drop event table and leave the test database empty
scripts/mysql_create_system_tables.sh:
  add missing create table statement
scripts/mysql_fix_privilege_tables.sql:
  don't specify the database. this fixes a failing test case which creates the
  tables not on mysql but on a test database and then tests again mysql.

This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().

Shortened a bit the runtime for executing events test cases.

  When looking up the error number for named errors in mysqltest .test
  files, we inadvertantly would match ER_WRONG_VALUE against
  ER_WRONG_VALUE_COUNT because we were using the length of the shorter
  string in strncmp(). Now we double-check the length of matches to
  make sure it was a complete match.


client/mysqltest.c:
  Check the length of the error name to make sure it wasn't just a
  partial match
mysql-test/t/events.test:
  Replace error numbers with error names, with side-effect of testing
  Bug #18495.

-												WL#3337 (Events new architecture)
This cut No 7 should finish the part of fixing the parsing of the events :
- Event_timed is no more used during parsing. Less problems because it has
  a mutex. Event_parse_data class is used during parsing. It is suited only
  for this purpose. It's pretty lightweight
- Late checking of data from parsing is being performed. This should solve
  the problems of nested events in SP or other events (for the situation 
  of no nested bodies). Before if an ALTER EVENT was in a SP, then when the
  SP was compiled, and not executed, the actual init_xxx methods of Event_timed
  were called, which is wrong.
- It could be a side effect of using a specialized class, but test events_stress is
  now 25% quicker.

Cut No8 will start splitting Event_scheduler into 2 parts, the QUEUE will be moved
to Event_queue.

-												Bug #18495: mysqltest does not use the correct error number

  When looking up the error number for named errors in mysqltest .test
  files, we inadvertantly would match ER_WRONG_VALUE against
  ER_WRONG_VALUE_COUNT because we were using the length of the shorter
  string in strncmp(). Now we double-check the length of matches to
  make sure it was a complete match.


client/mysqltest.c:
  Check the length of the error name to make sure it wasn't just a
  partial match
mysql-test/t/events.test:
  Replace error numbers with error names, with side-effect of testing
  Bug #18495.

-												WL#3337 (Events new architecture)
This cut No 7 should finish the part of fixing the parsing of the events :
- Event_timed is no more used during parsing. Less problems because it has
  a mutex. Event_parse_data class is used during parsing. It is suited only
  for this purpose. It's pretty lightweight
- Late checking of data from parsing is being performed. This should solve
  the problems of nested events in SP or other events (for the situation 
  of no nested bodies). Before if an ALTER EVENT was in a SP, then when the
  SP was compiled, and not executed, the actual init_xxx methods of Event_timed
  were called, which is wrong.
- It could be a side effect of using a specialized class, but test events_stress is
  now 25% quicker.

Cut No8 will start splitting Event_scheduler into 2 parts, the QUEUE will be moved
to Event_queue.

This patch introduces specialized Event data objects
Event_basic as parent.
Event_queue_element used for queue storage
Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT
Event_job_data using during execution.
Methods were moved out of Event_timed to other classes.

This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().

Shortened a bit the runtime for executing events test cases.

-												WL#3337 (Event scheduler new architecture)
This patch introduces specialized Event data objects
Event_basic as parent.
Event_queue_element used for queue storage
Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT
Event_job_data using during execution.
Methods were moved out of Event_timed to other classes.

This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().

Shortened a bit the runtime for executing events test cases.

SHOW AUTHORS caused 'Packets out of order' in stored functions:
add the corresponding SQLCOM to sp_get_flags_for_command so that
it'd return sp-related flags for it.

-												- fix for bug #16414 (Events: Crash or hang if event drops itself)
WL#1034 (Internal CRON)
(with post-review fix)


mysql-test/r/events.result:
  update the result
mysql-test/t/events.test:
  use --sleep instead of select sleep()
  enable some scheduler related tests. They were disabled because of a hang that
  happened. The hang is fixed with this bugfix.
sql/event.cc:
  - evex_remove_from_cache reports back whether the in_memory
    object was deleted or was scheduled. In case scheduling then
    don't delete it from outside but let it do it itself
  - move out db interaction code out of evex_drop_event to db_drop_event
    so it can be called from outter space :)
sql/event_priv.h:
  - export the new function db_drop_event()
sql/event_timed.cc:
  - use db_drop_event() and don't implement the dropping ourselves
sql/sql_parse.cc:
  - some debug info about the status code returned.

-												fix for bug #17619 Scheduler race conditions
- 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

  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.

      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
