the lexer API which internally uses unsigned char variables to
address its state map. The implementation of the lexer should be
internal to the lexer, and not influence the rest of the code.
Removed wrong fix for the bug#27006.
The bug was added by the fix for the bug#19978 and fixed by Monty on 2007/02/21.
trigger.test, trigger.result:
Corrected test case for the bug#27006.
BUG#26429: SHOW CREATE EVENT is incorrect for an event that
STARTS NOW()
BUG#26431: Impossible to re-create an event from backup if its
STARTS clause is in the past
WL#3698: Events: execution in local time zone
The problem was that local times specified by the user in AT, STARTS
and ENDS of CREATE EVENT/ALTER EVENT statement were converted to UTC,
and the original time zone was forgotten. This way, event scheduler
couldn't honor Daylight Saving Time shifts, and times shown to the
user were also in UTC. Additionally, CREATE EVENT didn't allow times
in the past, thus preventing straightforward event restoration from
old backups.
This patch reworks event scheduler time computations, performing them
in the time zone associated with the event. Also it allows times to
be in the past.
The patch adds time_zone column to mysql.event table.
NOTE: The patch is almost final, but the bug#9953 should be pushed
first.
UPDATE if the row wasn't actually changed.
This bug was caused by fix for bug#19978. It causes AFTER UPDATE triggers
not firing if a row wasn't actually changed by the update part of the
INSERT .. ON DUPLICATE KEY UPDATE.
Now triggers are always fired if a row is touched by the INSERT ... ON
DUPLICATE KEY UPDATE.
- Crash occured because Event engine is only initialized if
ACLs are used but not properly marked as disabled.
- The patch is to mark the Event engine as DISABLED if no ACLs
are used to avoid access of uninitialized variables.
- Stored procedures returning unsinged values returns signed values if
text protocol is used. The reason is that the stored proceedure item
Item_func_sp wasn't initializing the member variables properly based
on the information contained in the associated result field.
- The patch is to upon field-item association, ::fix_fields, initialize
the member variables in appropriate order.
- Field type of an Item_func_sp was hard coded to MYSQL_TYPE_VARCHAR.
This is changed to return the type of the actual result field.
- Member function name sp_result_field was refactored to the more
appropriate init_result_field.
- Member function name find_and_check_access was refactored to
sp_check_access.
INSERT uses query_id to verify what fields are
mentioned in the fields list of the INSERT command.
However the check for that is made after the
ON DUPLICATE KEY is processed. This causes all
the fields mentioned in ON DUPLICATE KEY to be
considered as mentioned in the fields list of
INSERT.
Moved the check up, right after processing the
fields list.
