Below is the list of changes that have just been committed into a local 5.1 repository of andrey. When andrey does a push these changes will be propagated to the main repository and, within 24 hours after the push, to the public repository. For information on how to access the public repository see http://dev.mysql.com/doc/mysql/en/installing-source-tree.html ChangeSet 1.2389 06/05/16 12:52:28 andrey@lmy004. +7 -0 Fix for bug #17394 - Events namespace is wrong This second patch adds test cases for SHOW EVENTS/SELECT FROM I_S.EVENTS and implements change of definer during ALTER EVENT. DROP EVENT is already implemented.
