MySQL Bugs: #27408: Alter table ADD partition .... with Data Directory causes MySql Server to crash

Bug #27408	Alter table ADD partition .... with Data Directory causes MySql Server to crash
Submitted:	23 Mar 2007 19:28	Modified:	16 Oct 2007 16:42
Reporter:	Yuriy Maksimov	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Server: Partitions	Severity:	S1 (Critical)
Version:	5.1.16/5.1BK	OS:	Windows (MS Windows Server 2003)
Assigned to:	Alexey Botchkov	CPU Architecture:	Any

Description:
Adding a new partition to the table with PARTITION BY LIST crashes the server if DATA and INDEX DIRECTORY options are used.

-- Here is the table definition: 

CREATE TABLE `t2` ( 
`col1` int(11) DEFAULT NULL 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 
PARTITION BY LIST ( col1) 
(partition p1 values in (null)); 

-- then I try to add a new partition - this works fine 

alter table t2 
add partition 
(partition p2 values in (1)); 

show create table t2; 

-- CREATE TABLE `t2` ( 
-- `col1` int(11) DEFAULT NULL 
-- ) ENGINE=InnoDB DEFAULT CHARSET=utf8 
 /*!50100 PARTITION BY LIST ( col1) 
 (PARTITION p1 VALUES IN (NULL) ENGINE = InnoDB, 
 PARTITION p2 VALUES IN (1) ENGINE = InnoDB) */ 

-- then try to add another partition with DATA and INDEX DIRECTORY - this one   
-- crashes MySql server. 

alter table t2 
add partition 
(partition p3 values in (2) 
data directory = 'C:\TestDB' 
index directory = 'C:\TestDB' 
); 

-- Those folder exists, my account has all possible rights, MySql 5.1.16 on
-- Windows server 2003, MySql runs as a service, Engine=InnoDB. 

How to repeat:
Execute the code above.

Thank you for the bug report. I was only able to repeat with Windows
version with current source tree.

It's another form of the #26074
http://bugs.mysql.com/bug.php?id=26074

still initial testcase should be checked when 26074 is pushed
