Description
MariaDB server version 10.2.14 (build 22257 and build from current source) from bb-10.2-compatibility branch crashes while executing ALTER TABLE that changes TIMESTAMP column and sets '' as default value for it.
Consider the following table:
CREATE TABLE tbug (
|
id int(11) NOT NULL AUTO_INCREMENT,
|
fn varchar(50) NOT NULL DEFAULT '0',
|
data longtext NOT NULL DEFAULT '0',
|
more_data longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT '0',
|
even_more_data longtext DEFAULT '0',
|
udate timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(),
|
uby varchar(50) NOT NULL,
|
PRIMARY KEY (fn),
|
KEY `id` (id)
|
) ENGINE=InnoDB;
|
with 21 rows of data inserted as follows:
...
|
MariaDB [test]> insert into tbug(fn, data, more_data, even_more_data, uby) values(rand()*10000, repeat('a', 10000), repeat('b', 2000), repeat('c', 3000), rand()*100);
|
Query OK, 1 row affected (0.03 sec)
|
|
|
MariaDB [test]> insert into tbug(fn, data, more_data, even_more_data, uby) values(rand()*10000, repeat('a', 10000), repeat('b', 2000), repeat('c', 3000), rand()*100);
|

|
Query OK, 1 row affected (0.04 sec)
|
|
|
MariaDB [test]> show create table tbug\G
|
*************************** 1. row ***************************
|
Table: tbug
|
Create Table: CREATE TABLE `tbug` (
|
`id` int(11) NOT NULL AUTO_INCREMENT,
|
`fn` varchar(50) NOT NULL DEFAULT '0',
|
`data` longtext NOT NULL DEFAULT '0',
|
`more_data` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT '0',
|
`even_more_data` longtext DEFAULT '0',
|
`udate` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(),
|
`uby` varchar(50) NOT NULL,
|
PRIMARY KEY (`fn`),
|
KEY `id` (`id`)
|
) ENGINE=InnoDB AUTO_INCREMENT=21 DEFAULT CHARSET=latin1
|
1 row in set (0.00 sec)
|
Now, if we try to run this ALTER in default sql_mode:
MariaDB [test]> ALTER TABLE tbug CHANGE COLUMN udate udate TIMESTAMP NULL DEFAULT '' ON UPDATE CURRENT_TIMESTAMP AFTER even_more_data;
|
ERROR 1292 (22007): Incorrect datetime value: '' for column 'udate' at row 1
|
MariaDB [test]> select @@sql_mode;

|

|
it is not accepted, but when we try to set sql_mode to oracle it crashes:
MariaDB [test]> set sql_mode=oracle;
|
Query OK, 0 rows affected (0.00 sec)
|
|
|
MariaDB [test]> select @@sql_mode;

Other, a bit different stack trace, was noted on build 22257 with a simuilat table and ALTER (that can not be shared in public) by a user:

This could be because you hit a bug. It is also possible that this binary

or one of the libraries it was linked against is corrupt, improperly built,
