From 19990c92197c64588ac489fda6c23e34702d7db0 Mon Sep 17 00:00:00 2001 From: Venkata Sidagam Date: Thu, 31 Oct 2013 23:02:44 +0530 Subject: Bug #12917164 DROP USER CAN'T DROP USERS WITH LEGACY UPPER CASE HOST NAME ANYMORE Description: It is not possible to drop users with host names with upper case letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing with error. Analysis: Since the fix 11748570 we came up with lower case hostnames as standard. But in the current bug the hostname is created by mysql_install_db script is still having upper case hostnames. So, if we have the hostname with upper case letters like(Tmp_Host_Name) then we will have as it is stored in the mysql.user table. In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives error because we do compare with the lower case of hostname since the 11748570 fix. Fix: We need to convert the hostname to lower case before storing into the mysql.user table when we run the mysql_install_db script. --- scripts/mysql_system_tables_fix.sql | 3 +++ 1 file changed, 3 insertions(+) (limited to 'scripts/mysql_system_tables_fix.sql') diff --git a/scripts/mysql_system_tables_fix.sql b/scripts/mysql_system_tables_fix.sql index 09f66c79c3f..56f6a64211a 100644 --- a/scripts/mysql_system_tables_fix.sql +++ b/scripts/mysql_system_tables_fix.sql @@ -601,6 +601,9 @@ ALTER TABLE db MODIFY Trigger_priv enum('N','Y') COLLATE utf8_general_ci DEFAULT UPDATE user SET Trigger_priv=Super_priv WHERE @hadTriggerPriv = 0; +# Convering the host name to lower case for existing users +UPDATE user SET host=LOWER( host ) WHERE LOWER( host ) <> host; + # Activate the new, possible modified privilege tables # This should not be needed, but gives us some extra testing that the above # changes was correct -- cgit v1.2.1
