when there are no up-to-date system tables to support it: - initialize the scheduler before reporting "Ready for connections". This ensures that warnings, if any, are printed before "Ready for connections", and this message is not mangled. - do not abort the scheduler if there are no system tables - check the tables once at start up, remember the status and disable the scheduler if the tables are not up to date. If one attempts to use the scheduler with bad tables, issue an error message. - clean up the behaviour of the module under LOCK TABLES and pre-locking mode - make sure implicit commit of Events DDL works as expected. - add more tests Collateral clean ups in the events code. This patch fixes Bug#23631 Events: SHOW VARIABLES doesn't work when mysql.event is damaged

# There are various conditions when a server would regard mysql.event
|
|
# table as damaged:
|
|
# - the table has more column than specified in the compiled in value, but
|
|
# the version of the server which created the table is the same
|
|
# - the column count in the table is less than the compiled in value
|
|
# - some column has an incompatible type specification (for what is an
|
|
# incompatible type specification please refer to the comments in the source
|
|
#
|
|
# Unfortunately, in order to test a condition, we need to restart the
|
|
# server. Therefore, here we test only one simple case: changing the data
|
|
# type of the 'body' field to blob.
|
|
#
|
|
# First, let's do a backup to not depend on actual definition of mysql.event
|
|
create table event_like like mysql.event;
|
|
insert into event_like select * from mysql.event;

# Now let's alter the table and restart the server
