Events: Event-caused statements don't appear in the slow query log
WL#1034
sql/event_executor.cc:
enable slow logging
sql/event_timed.cc:
enable slow logging for the anonymous SP
sql/sp_head.cc:
allow thd->enable_slow_log to be TRUE if only
m_flags & sp_head::LOG_SLOW_STATEMENTS
Because usually enable_slow_log is 1 in user mode, this second
check is needed backup the mode otherwise.
sql/sp_head.h:
add a new constant for slow queries. SP by default does not log slow queries in the
body just the whole CALL could be considered as slow if taking too much time and
called directly from the user
sql/sql_parse.cc:

new test cases for bug #16537 (Events: mysql.event.starts is null)
sql/event.cc:
- check whether event_timed::starts_null only in case
event_timed::expression is set, so for recurring events only
- disable binlogging of CREATE EVENT statement. It should not be
replicated but the result of the execution. Still the replication is
untouched topic.
sql/event.h:
- add flags whether starts, ends and execute_at are null or not
sql/event_executor.cc:
- check whether xxx_null instead of !xxxx.year

- This changeset also changes the executor so its quite more stable now.
Stressing test case added that executes ~800 events per second and dropping

mysql-test/t/events.test:
-redundant line
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
sql/event.cc:
- make this not unsigned. gcc complains
sql/event_timed.cc:
acl_getroot_no_password() is not there in libmysqld, disable it's usage
in this case.
sql/set_var.cc:
fix for the broken build of Serg. gcc seems to be pretty happy without
the return and returns the value of the last statement

- 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:

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
WL#1034 (Internal CRON)

mysql-test/t/events.test:

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

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.

of an event when it's altered. also fix for bug#16431
sql/event_executor.cc:

sql/event_timed.cc:

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
Before the interval expression was considered to be in seconds, now it is
just a number and the type of interval is considered.
- this changeset introduces also fix for bug#16432 (Events: error re interval
misrepresents the facts)
the code of event_timed::set_interval() was refactored anyway so it is meaningful to
fix the bug in the same changeset.
include/my_time.h:
- move enum interval_type to include/my_time.h so it can be used by functions
in the whole server
sql/event.cc:

- fix small problem with create event xyz, when xyz exists -> make it error
instead of warning if create_if_not is false.
sql/event.h:

- handle error returned by event_timed::compute_next_execution_time()
sql/event_priv.h:
- define the maximal possible value for interval_value
sql/event_timed.cc:

- add static get_next_time() which sums a TIME with an interval
- fix bug #16435 (Weekly events execute every second)
Before the interval expression was considered to be in seconds, now it is

sql/item_timefunc.cc:
- export get_interval_date()
- refactor Item_date_add_interval::get_date() and extract the core
to date_add_interval() in time.cc so it can be reused by the
scheduler code in event_timed.cc
sql/item_timefunc.h:
- export get_interval_value() so it can be reused in event_timed.cc in
function static get_next_time()
- move enum interval_type to include/my_time.h so it can be used by functions
in the whole server
sql/mysql_priv.h:

#there is a major problem currently after removing the specialised DYNAMIC_ARRAY as
storage for the events. I have to reintroduce similar storage, this time probably some
linked list or maybe some API on top of DYNAMIC_ARRAY.
sql/event.cc:
close the table
sql/event.h:
change definition
sql/event_executor.cc:
don't start the thread in advance
sql/event_timed.cc:
- don't call evex_drop_event
- quote the name during compilation to make create event `the rain in spain goes into the drain` not fail.
- handle crashes where the table definition has been changed
(different number of fields)
sql/event.cc:
change the way table is opened
check whether the number of fields is exact, otherwise report damaged table
sql/event_executor.cc:
- move around some code
- use the new way of table opening
sql/event_priv.h:
- new declaration
sql/event_timed.cc:
- now 0 is ok
- 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;
- fixed silly bug, the main thread restarted but did not execute events,
Quite currious why many calls to pthread_mutex_init() do not lead to abort()
sql/event.cc:
- remove mysql_event_table_exists
- fix possible crash when table is 0x0
sql/event_executor.cc:
- make event_executor_running_global_var volatile
- fix erroneous reinitilization of a mutex, why did it not crash in debug mode?
why pthread_mutex_init() does not abort() in case the mutex was not deinitted
beforehand?
- first initialization of event_executor_running_global_var inside init_mutexes()
- remove debug if()
sql/event_priv.h:
- remove unneeded definitions
sql/event_timed.cc:
make backup and then restore the open table state of thd
(cleanups, leaks fixed)
sql/event.cc:
- update comments
- remove dead code
- event_timed is no more copied after allocation on a DYNAMIC_ARRAY
because there is a problem when the array is reallocated - we get
dangling pointers from the scheduling queue. anyway it makes little
sense to keep them there except that cleaning is quite efficient but
iterating over all events and cleaning them one by one is not that bad
considering that happens only when the main scheduler thread is killed
or during server shutdown.
sql/event_executor.cc:
- DYNAMIC_ARRAY is no more
sql/event_priv.h:
- remove unneeded code/defines. the scheduler's queue is of
type QUEUE and cannot run anymore on top of DYNAMIC_ARRAY
sql/event_timed.cc:
- after parsing (in ::compile() ) destruct the event_timed object
sql/sql_parse.cc:
in case of syntax error clean up lex->et because there could be an object
created. as in the code the same is done for SPs.
cleanup before throwin away DYNAMIC_ARRAY for event storage,
once reallocated I get dangling pointers so that's not good.
solution will be found however ;)
sql/event.cc:
- remove unneeded variables
- remove commented out code
- remove non-cs compliant comment
- fix a bug when removing from memory cache
- better close the tables than relying on sql_parse.cc::do_command()
to do that
sql/event_executor.cc:
- cleanup
sql/event_priv.h:
-cleanup
sql/event_timed.cc:
cleanup
QUEUE implementation working now. this should be ready more or less
for testing once the debug output is being cleaned and some things
around DYNAMIC_ARRAY are cleaned
- fix handling in case of errors that lead to crashes, now no more crashes
in case of table corruption and such.
include/queues.h:
introduce a safe version of queue_insert that will extend the queue if
necessary. the auto_extent is passed to the _ex version of init_queue()
mysys/queues.c:
add init_queue_ex() implementation
add queue_insert_safe() implementation
sql/event.cc:
- move mysql_priv.h inclusion to event_priv.h
- use a priority queue instead of DYNAMIC_ARRAY which is sorted
sql/event.h:
reorder
sql/event_executor.cc:
reorder
sql/event_priv.h:
- reorder a bit
- add macroses and functions for queue manipulation which stay on top
of QUEUE (partly implemented for DYNAMIC_ARRAY but will be cleared to be
only for QUEUE).
sql/event_timed.cc:
allocate one more byte and zeroterminate, really
- handle better non-latin1 identifiers
sql/event.cc:
- introduce a wrapper to compare easily and correctly
LEX_STRINGs
- remove few unneeded variables
- remove need_second_pass by restructuring the code. this brings
performance boost because the code bails out from the loop once
it hits what it looks for
- handle ALTER EVENT name RENAME TO name (throw an error message).
sql/event_executor.cc:
- comment about DBUG_FAULTY_THR
- indent fix
sql/event_timed.cc:
- fix a problem when event name is not latin1. a cyrillic event name
was crashing the parser so the I emulate SET NAMES utf8. The data is
already in utf8, being loaded from the disk.
sql/share/errmsg.txt:
add new error message
- fix a bug introduced with last commit ALTER EVENT a RENAME TO b; failed
- misc
sql/event.cc:
- rename evex_db_find_routine_aux() to evex_db_find_event_aux() (better name)
- change parameter order of db_update_event()
- last bits to handle errors as close as possible to the place they occur
- fix a bug introduced with last commit: first check for overwriting and event and then
check whether the original one exists
sql/event.h:
add a new error code returned by event_timed::compile() in case of
error
sql/event_priv.h:
rename
sql/event_timed.cc:
- function rename
- add a bit of doc
sql/share/errmsg.txt:
- extend an error message so it's more informative
- add a new error message
sql/sql_parse.cc:
refactor the cases for CREATE/ALTER/DROP event so use as much common
code as possible. last bits of error checking unneeded in sql_parse.cc
thrwon out.
