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

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)
