This also should fix 17493 and 17346, and probably 16397 (not tested).
WL#1034 (Internal CRON)
(post-review commit)
mysql-test/r/events.result:
update result
mysql-test/t/events.test:
update test
sql/event.cc:
seems we get a crash if we compile it this way. better let the worker thread do it,
this increases the stability.
sql/event_executor.cc:
kick in more often
sql/event_timed.cc:
- don't NULLify last_executed
- implement (fix) better get_next_time() which does not use last_executed as basis
but STARTS. STARTS is used as basis and the next point of time which is before ENDS,
if set, is being found. The point > now and (point-starts) % interval_expression == 0.
sql/item_timefunc.cc:
move calc_time_diff to time.cc as it can be reused in other parts of the
server code (see event_timed.cc)
sql/mysql_priv.h:
export calc_time_diff() moved to time.cc from item_timefunc.cc
sql/sql_show.cc:
- fix presenting of LAST_EXECUTED
- cleanup a bit
sql/time.cc:
- move calc_time_diff() from item_timefunc.cc to here
