10.0.28
Description
I create a file with a UTF8MB4 string:
SELECT CONCAT('aaa',0xF09F988E,'bbb') INTO OUTFILE '/tmp/test.txt'; |
where 0xF09F988E is UTF8MB4 encoding for the character "U+1F60E SMILING FACE WITH SUNGLASSES".
Now I load this file:
DROP TABLE IF EXISTS t1; |
CREATE TABLE t1 (a VARCHAR(10) CHARACTER SET utf8); |
LOAD DATA INFILE '/tmp/test.txt' INTO TABLE t1 CHARACTER SET utf8; |
SHOW WARNINGS;
|
SELECT * FROM t1; |
Notice, the CHARACTER SET utf8 clause is wrong. It should be CHARACTER SET utf8mb4 instead. But the problem is that in 10.0.24 it loaded the data with a warning, and in 10.0.28 it fails with an error.
Results in 10.0.24:
MariaDB [test]> DROP TABLE IF EXISTS t1;

As a result, replication from a 10.0.24 master to a 10.0.28 slave stops with an error.
The bug was likely introduced after merging this commit from MySQL:
commit 9f7288e2e0179db478d20c74f57b5c7d6c95f793

BUG#23080148 - BACKPORT BUG 14653594 AND BUG 20683959 TO
|
MYSQL-5.5
|
|
The bug asks for a backport of bug#1463594 and bug#20682959. This
|
is required because of the fact that if replication is enabled, master
|
transaction can commit whereas slave can't commit due to not exact
|
'enviroment'. This manifestation is seen in bug#22024200.
