This is a post-review patch.
Fixes the typelib implementation, available only in 5.1.11.
--event-scheduler cmdline : DISABLED | ON | OFF | 0 | 1
DISABLED - makes the scheduler unavailable during the server run
(ON|1)- When the server is started the scheduler will be started. It can
be stopped and restarted by setting appropriate values to
GLOBAL event_scheduler
(OFF|0)- When the server is started, the scheduler won't be started. It
can be started and again stopped by setting appropriate values to
GLOBAL event_scheduler. _DEFAULT_ value
The GLOBAL variable event_scheduler can have the following values:
OFF | ON | 0 | 1
DISABLED is not possible and every attempt will end with an error that
it's not a valid value for the variable.
OFF | 0 - This is the pre-5.1.11 behavior - The scheduler stops, if not
already stopped, and can be started again by setting
the value of the variable to ON|1.
ON | 1 - This is the pre-5.1.11 behavior - The scheduler starts, if not
already started, and can be stopped again by setting the value
of the variable to OFF|0.
The 250 simultaneous events all accessing the same table caused the
events_stress test to fail due to debug warnings about too many table
waiters. Fixed by using three different tables.
- Scheduler is either initialized at server start or never.
Starting & stopping is now suspending & resuming.
- The scheduler has clear OO interface
- Now all calls to the scheduler are synchronous
- GLOBAL event_scheduler uses thd::sys_var_tmp (see set_var.cc)
- External API is encapsulated into class Events
- Includes fixes for all comments of Kostja's review of 19.05.2005
Starting to merge into 5.1-release (5.1.10) and push
WL#1034
- This changeset also changes the executor so its quite more stable now.
Stressing test case added that executes ~800 events per second and dropping
hundreds of events at once using DROP DATABASE.
