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.

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.

sql/event.cc:
Implemented evex_db_drop_events() which drops all events
from a specific database. Needed for SQLCOM_DROP_DATABASE
sql/event.h:
- protect the event better (see the changes to event_executor.cc
and event.cc). An event object could be used in a spawned thread
before it's executed but till now the object is marked as being
executed when the anonymous sp_head is executed. However, there are
timeframes before and after that during which the event is not marked
as executed and other thread may delete the object -> so we end with
a nirvana pointer.
sql/event_executor.cc:
- extract some of the code executed in the main thread to a function. Too long
functions are bad for the overview.
- prepend all information/error messages to the console with "SCHEDULER:" for
better overview, and easied searching in the log tables.
sql/event_priv.h:
- change the name, of evex_db_find_event_by_name() and don't
used C++ features like function overloading
- define consts for result returned from event_timed::spawn_now()
sql/event_timed.cc:
- add few methods related to event execution.
now the event spawns the worker thread and
passes itself as parameter. This way it locks itself for exectution
first and then spawning -> no race condition. When the worker thread
has finished working with the reference it calls back
event_timed::spawn_thread_finish() to unlock itself.
sql/sql_db.cc:
- call evex_drop_db_events() on DROP DATABASE

add test for Bug #16410 Events: CREATE EVENT is legal in a CREATE TRIGGER statement
sql/sp_head.cc:
CREATE/ALTER/DROP event mean explicit commit, so they are not allowed in
a FUNCTION/TRIGGER. Fixes bug#16410
sql/sql_parse.cc:
- end active transaction for CREATE/ALTER/DROP EVENT because
they are DDL statements.

- fix for bug#16423 (Events: SHOW CREATE EVENT doesn't work)
- this Changeset commits makes CREATE/UPDATE/DELETE EVENT real DDL statements
by committing the currently open transaction before they are executed.
- this Changeset also fixes a trailing space problem since the very early days
of the internal cron
- adds sophisticated checking of whether mysql.event was tampered accidentally
or with purpose by an user.
- adds a lot of inline function documentation - documents everything left
uncodumented
- INTERVAL_XXXX to XXX in I_S.EVENTS.INTERVAL_FIELD
WL#1034 (Internal CRON)
mysql-test/r/events.result:
update result
mysql-test/t/events.test:
add test cases for SHOW CREATE EVENT
add test cases where the structure of mysql.event is changed and error reporting in this case
sql/event.cc:
- do a lot more checking on mysql.event whether it's valid
introduced generic function table_check_intact() which can be used also
for checking whether a system table (mysql.*) has been tampered by user
and report an error in this case. The checking is quite strict, thus
maybe some mechanism can be added later that loosens this like some
session variable, for instance, i_am_aware_that_i_can_damage_my_data
so the table will be opened nevertheless we think that it's not valid.
- add evex_show_create_event(THD *thd, sp_name *spn, LEX_STRING definer)
- document a loooot. not a single function left undocumented.
sql/event.h:
- add evex_show_create_event(THD *thd, sp_name *spn, LEX_STRING definer)
- change get_show_create_event() to get_create_event()
- add TABLE_FIELD_W_TYPE used by table_check_intact()
- add event_timed::sql_mode so it can be used by show create event. currently
always 0, will be fixed by a patch for another bug. At least makes the code
of show create event complete.
sql/event_executor.cc:
- add evex_check_system_tables() that checks on boot and event
main thread startup that mysql.db and mysql.user tables are correct.
- document everything!
sql/event_priv.h:
remove a line
sql/event_timed.cc:
- implement SHOW CREATE EVENT
- document undocumented functions!
sql/share/errmsg.txt:
- fix an error message and add two new
sql/sql_acl.cc:
- add mysql.db table definition to use by table_check_intact()
- exchange some of the positions by numbers from mysql.db to enum names (see sql_acl.h)
sql/sql_acl.h:
- define the structure of mysql.db table
sql/sql_parse.cc:
- handle SQLCOM_SHOW_CREATE_EVENT
- end the current transaction becase CREATE/UPDATE/DELETE EVENT is a DDL
statement
sql/sql_show.cc:
- remove interval_type_to_name
- use common function event_reconstruct_interval_expression()
that reconstructs the expression given at create/alter, to some
extent - interval of 2:62 MINUTE_SECOND will be reconstructed as
interval of 3:02 MINUTE_SECOND!
sql/sql_yacc.yy:
init the definer of event_timed also when doing SHOW CREATE EVENT
because it's needed for checking into mysql.event
sql/table.cc:
- remove stale code. only mysql.event should be a 'system_table'
- add table_check_intact() to check the consistency of a table.
mostly usable with mysql.xxx tables.
sql/table.h:
- export TABLE_FIELD_W_TYPE and table_check_intact() which are used for
checking the structure of a table. mostly usable for mysql.xxx tables.
Events were executed with all privileges possible on planet Earth :(
WL#1034
mysql-test/r/events.result:
update test results
mysql-test/t/events.test:
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
- change from 2 arrays to a LEX_STRING array

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.

WL#1034 (Internal CRON)
This patch adds INFORMATION_SCHEMA.EVENTS table with the following format:
EVENT_CATALOG - MYSQL_TYPE_STRING (Always NULL)
EVENT_SCHEMA - MYSQL_TYPE_STRING (the database)
EVENT_NAME - MYSQL_TYPE_STRING (the name)
DEFINER - MYSQL_TYPE_STRING (user@host)
EVENT_BODY - MYSQL_TYPE_STRING (the body from mysql.event)
EVENT_TYPE - MYSQL_TYPE_STRING ("ONE TIME" | "RECURRING")
EXECUTE_AT - MYSQL_TYPE_TIMESTAMP (set for "ONE TIME" otherwise NULL)
INTERVAL_VALUE - MYSQL_TYPE_LONG (set for RECURRING otherwise NULL)
INTERVAL_FIELD - MYSQL_TYPE_STRING (set for RECURRING otherwise NULL)
SQL_MODE - MYSQL_TYPE_STRING (for now NULL)
STARTS - MYSQL_TYPE_TIMESTAMP (starts from mysql.event)
ENDS - MYSQL_TYPE_TIMESTAMP (ends from mysql.event)
STATUS - MYSQL_TYPE_STRING (ENABLED | DISABLED)
ON_COMPLETION - MYSQL_TYPE_STRING (NOT PRESERVE | PRESERVE)
CREATED - MYSQL_TYPE_TIMESTAMP
LAST_ALTERED - MYSQL_TYPE_TIMESTAMP
LAST_EXECUTED - MYSQL_TYPE_TIMESTAMP
EVENT_COMMENT - MYSQL_TYPE_STRING
SQL_MODE is NULL for now, because the value is still not stored in mysql.event .
Support will be added as a fix for another bug.
This patch also adds SHOW [FULL] EVENTS [FROM db] [LIKE pattern]
1. SHOW EVENTS shows always only the events on the same user,
because the PK of mysql.event is (definer, db, name) several
users may have event with the same name -> no information disclosure.
2. SHOW FULL EVENTS - shows the events (in the current db as SHOW EVENTS)
of all users. The user has to have PROCESS privilege, if not then
SHOW FULL EVENTS behave like SHOW EVENTS.
3. If [FROM db] is specified then this db is considered.
4. Event names can be filtered with LIKE pattern.
SHOW EVENTS returns table with the following columns, which are subset of
the data which is returned by SELECT * FROM I_S.EVENTS
Db
Name
Definer
Type
Execute at
Interval value
Interval field
Starts
Ends
Status
mysql-test/lib/init_db.sql:
change the PK - (definer, db, name)
quicker searches when SHOW EVENTS;
allow also different users to have events with the same name ->
no information disclosure

scripts/mysql_create_system_tables.sh:
change the PK of mysql.event to (definer, db, name)
scripts/mysql_fix_privilege_tables.sql:
change the PK of mysql.event to (definer, db, name)
sql/event.cc:
pass around the definer of the event because of the new PK
which is (definer, db, name). It's needed for index searching.
sql/event.h:
- make enum evex_table_field again public so it can be used
in sql_show.cc
- make created and modified ulonglong, because they should be such
- make public evex_open_event_table so it can be used in sql_show.cc
sql/event_executor.cc:
- cosmetics
sql/event_priv.h:
- moved enum evex_table_field and evex_open_event_table()
to event.h (made them therefore public)
sql/event_timed.cc:
- in event_timed::init_definer() always fill this.definer with
the concatenated value of definer_user@definer_host. Makes
later the work easier.
- pass around the definer wherever is needed for searching
(new prototype of evex_db_find_evex_aux)
sql/mysqld.cc:
- add counter for SHOW EVENTS
sql/sql_lex.h:
- register SHOW EVENTS as command
sql/sql_parse.cc:
- handle SCH_EVENTS (I_S.EVENTS like SCH_TRIGGERS)
- make additional check in case of SHOW EVENTS (check for EVENT on
the current database. if it is null check_access() gives appropriate
message back.
sql/sql_show.cc:
- add INFORMATION_SCHEMA.EVENTS and SHOW EVENTS
- I_S.EVENTS.SQL_MODE is NULL for now -> not implemented. Trudy
asked to be added so bug #16642 can be completely closed. There
is another bug report which will fix the lack of storage of
SQL_MODE during event creation.
sql/sql_yacc.yy:
- always call event_timed::init_definer() when CREATE/ALTER/DROP
EVENT but not when just compiling the body of the event because
in this case this operation is not needed, it takes memory and
CPU time and at the end the result is not used. event_timed::definer
is used only on SQLCOM_CREATE/ALTER/DROP_EVENT execution not on
statement compilation.
- add SHOW [FULL] EVENTS [FROM db] [LIKE pattern]
in case of FULL and the user has PROCESS privilege then he will see
also others' events in the current database, otherwise the output
is the same as of SHOW EVENTS. Because the events are per DB only
the events from the current database are shown. pattern is applied
against event name. FROM db is self explanatory.
sql/table.h:
add SCH_EVENTS as part of INFORMATION_SCHEMA

of an event when it's altered. also fix for bug#16431
sql/event_executor.cc:
be more verbose and throw more errors
sql/event_timed.cc:
- add ` around the names of the db and the event_name and not
their concatenation. remove ; from the end - unneeded. this fixes bug #16431,
which was failing because after some recursion the query was ending on ;;
which is normally an error in the parser because that's the delimiter
- more debug info
- don't execute lex_end() two times when there's a parse error or thd->is_fatal_error

sql/event_executor.cc:
if asked to stop -> stop.
- fixed test results
- fixed bug caught by information_schema.test . Bison temporal
variables are very nice but extremely error-prone (Count one more

- 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;
