Alexander Nozdrin	f392eddabc	Revert a patch for Bug#48231, which introduced valgrind warnings. Original revision: ------------------------------------------------------------ revision-id: li-bing.song@sun.com-20100130124925-o6sfex42b6noyc6x parent: joro@sun.com-20100129145427-0n79l9hnk0q43ajk committer: <Li-Bing.Song@sun.com> branch nick: mysql-5.1-bugteam timestamp: Sat 2010-01-30 20:49:25 +0800 message: Bug #48321 CURRENT_USER() incorrectly replicated for DROP/RENAME USER; REVOKE/GRANT; ALTER EVENT. The following statements support the CURRENT_USER() where a user is needed. DROP USER RENAME USER CURRENT_USER() ... GRANT ... TO CURRENT_USER() REVOKE ... FROM CURRENT_USER() ALTER DEFINER = CURRENT_USER() EVENT but, When these statements are binlogged, CURRENT_USER() just is binlogged as 'CURRENT_USER()', it is not expanded to the real user name. When slave executes the log event, 'CURRENT_USER()' is expand to the user of slave SQL thread, but SQL thread's user name always NULL. This breaks the replication. After this patch, All above statements are rewritten when they are binlogged. The CURRENT_USER() is expanded to the real user's name and host. ------------------------------------------------------------	16 years ago

davi@moksha.local	cb7486b4bf	Bug#21975 Grant and revoke statements are non-transactional Bug#21422 GRANT/REVOKE possible inside stored function, probably in a trigger Bug#17244 GRANT gives strange error message when used in a stored function GRANT/REVOKE statements are non-transactional (no explicit transaction boundaries) in nature and hence are forbidden inside stored functions and triggers, but they weren't being effectively forbidden. Furthermore, the absence of implict commits makes changes made by GRANT/REVOKE statements to not be rolled back. The implemented fix is to issue a implicit commit with every GRANT/REVOKE statement, effectively prohibiting these statements in stored functions and triggers. The implicit commit also fixes the replication bug, and looks like being in concert with the behavior of DDL and administrative statements. Since this is a incompatible change, the following sentence should be added to the Manual in the very end of the 3rd paragraph, subclause 13.4.3 "Statements That Cause an Implicit Commit": "Beginning with MySQL 5.0.??, the GRANT and REVOKE statements cause an implicit commit."
