Description
Let's create a simple table on our master server:
CREATE DATABASE slave_conversion_test;
|
|
|
CREATE TABLE slave_conversion_test.tab (
|
id int(10) unsigned NOT NULL,
|
data varchar(50),
|
PRIMARY KEY(id)
|
);
|
And then we can insert some data. To reproduce this issue, we need to make sure that the most significant bit of one of the integer values is '1':
INSERT INTO slave_conversion_test.tab (id, data) VALUES (1, 'str');
|
INSERT INTO slave_conversion_test.tab (id, data) VALUES (2147483647, 'str');
|
INSERT INTO slave_conversion_test.tab (id, data) VALUES (4294967295, 'str');
|
Now let's change the 'id' column to 'bigint' on the slave:
STOP SLAVE;
|
ALTER TABLE slave_conversion_test.tab MODIFY id BIGINT NOT NULL;
|
We also need to set slave_type_conversions to ALL_NON_LOSSY to make this work:
SET GLOBAL slave_type_conversions=ALL_NON_LOSSY;
|
START SLAVE;
|
Now back on the master, let's try to update these rows:
UPDATE slave_conversion_test.tab SET data='newstr' WHERE id=2147483647;
|
UPDATE slave_conversion_test.tab SET data='newstr' WHERE id=4294967295;
|
Now what data do we see on the slave:
MariaDB [(none)]> SELECT * FROM slave_conversion_test.tab;
|
+------------+--------+
|
| id | data |
|
+------------+--------+
|
| 1 | str |
|
| 2147483647 | newstr |
|
| 4294967295 | str |
|
+------------+--------+
|
3 rows in set (0.00 sec)
|
The row with 'id' value 4294967295 created an error on the slave:
MariaDB [(none)]> SHOW SLAVE STATUS\G

The slave seems to want to interpret the id value in the Update_rows_v1 event as a negative integer, since the most significant bit is 1.
The master in this case is MySQL 5.5, if that makes a difference.
