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.
mysql-test/r/events.result:
update result
mysql-test/t/events.test:
disabled is actually wrong, should be disable, but because of the early
checking it was never parsed.
sql/event_data_objects.cc:
move add init_xxx methods from Event_timed to Event_parse_data
Event_parse data does not need definer_user and definer_host
in Event_timed::compile() do not use lex.et, well there is no more lex.et :)
sql/event_data_objects.h:
move parsing responsibilities from Event_timed to Event_parse_data
sql/event_db_repository.cc:
No more Event_timed comes from parsing but Event_parse_data
The initialization of Item*-s from parsing is done late, and not
during the actual parsing. This is the right way to go because

executed (initialized) during parsing, as it was done.

sql/sql_lex.cc:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
sql/sql_lex.h:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
sql/sql_parse.cc:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
ACL checks were moved inside the Events subsystem.
Also ending of the transaction is performed only just
before doing disk operation. Therefore only when needed.
sql/sql_yacc.yy:
lex->et and lex->et_parse_phase are no more
Use the specialized for parsing Event_parse_data

db_repository is no more embedded in the Events

won't mean recompile of all files in the server which include events.h

Cut number 6. Move code from sql_show.cc to event_db_repository.cc
that more belongs to the latter.
sql/event_db_repository.cc:
move code that works with mysql.event from sql_show.cc to
event_db_repository.cc . Route through Event_db_repository's interface
which is proxied by class Events. The code relies on a function from
sql_show.cc which does the actual storage in the schema table. I think
it's better to leave the function there because the structure of
I_S.EVENTS is defined in sql_show.cc
sql/event_db_repository.h:
I_S / SHOW EVENTS handling hooks
sql/event_scheduler.cc:
use the pointer to db_repository which Event_scheduler already has
sql/events.cc:
Put a comment to get_instance
sql/events.h:
callback for I_S (sql_show.cc)
sql/sql_show.cc:
move code that belongs more to Event_db_repository than to here.
Use a callback of class Events. Only 1 function is left here, because
it copies data into the actual rows of I_S.EVENTS and belongs to this file.
sql/sql_show.h:
export this function will be called from event_db_repository.cc
5th cut, moved DB related code to Event_db_repository and
updated accordingly the remanining code.
Moved change/restore_security_context() to class THD
Removed events_priv.h
Next step is to reorganize create/update_event() and parsing for them.
But probably some other refactoring could be done in the meanwhile.
The changes so far pass the test suite.

Third cut to simplify parsing phase. Now DROP EVENT works.
Overloaded few functions to be able to use either sp_name or pass two LEX_STRINGs
instead of a Event_timed pointer. This is transitional and eventually the old
functions will be removed. For now DROP EVENT also works, does not need anymore
a parsing object (Event_timed) and definer initialization because everyone who
has EVENT_ACL can drop events, and this is checked on execution time in sql_parse.cc
from the security context, as it should be.
sql/event_data_objects.cc:
overload few functions
sql/event_scheduler.cc:
Event_scheduler::drop_event() actually does not need Event_timed object
but just an identifier, hence pass only sp_name.
Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
the old version will be removed. This is being done as transitional step to
be able to test frequently code.
sql/event_scheduler.h:
Event_scheduler::drop_event() actually does not need Event_timed object
but just an identifier, hence pass only sp_name.
Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
the old version will be removed. This is being done as transitional step to
be able to test frequently code.
sql/events.cc:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events.h:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events_priv.h:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/sql_parse.cc:
SQLCOM_DROP_EVENT does not need lex->event_parse_data object and
is more like SQLCOM_SHOW_CREATE_EVENT. Therefore, move it to the block that
handles the latter.
sql/sql_yacc.yy:
DROP EVENT does not need a parsing object, just a name.
Store it as lex->spname. Pretty similar handling to the one of
SHOW CREATE EVENT.
Second cut of separating parsing phase from execution phase
Separate Event_timed from parsing phase and introducing Event_parse_data.
sql/event_data_objects.cc:
second cut,
copy Event_timed::init_body() to Event_parse_data::init_body()
Init the body during parsing, everything else keep as a pointer to
Item or some other pointer to use for later initialization.
sql/event_data_objects.h:
get the identifier as sp_name*, later will initialize our structures
sql/events.cc:
for easy transition add temporarily parse_data, later Event_timed *et will be removed.
Do slow transition because Event_timed is so tightly integrated that a front-attack
by removing things from this class was unsuccessful. Do things step by step by eliminating
dependencies. Hence, the code could be checked with the current test suite too
(early testing)
