[MDEV-4564] ALTER on a temporary table generates an audit event - Jira

A comment in audit_null.test says "temp table generates no audit events", but ALTER TABLE still does. I'm not sure if it's intentional.

Test output:

install plugin audit_null soname 'adt_null';

create temporary table t1 (i int);

alter table t1 add j int;

drop table t1;

uninstall plugin audit_null;

Warnings:

Warning	1620	Plugin is busy and will be uninstalled on shutdown

root[root] @ localhost []	>> create temporary table t1 (i int)

root[root] @ localhost []	>> alter table t1 add j int

root[root] @ localhost []	test.t1 : alter

root[root] @ localhost []	>> drop table t1

root[root] @ localhost []	>> uninstall plugin audit_null

root[root] @ localhost []	mysql.plugin : write

Test case:

install plugin audit_null soname 'adt_null';

create temporary table t1 (i int);

alter table t1 add j int;

drop table t1;

uninstall plugin audit_null;

let $MYSQLD_DATADIR= `SELECT @@datadir`;

cat_file $MYSQLD_DATADIR/audit_null_tables.log;
