Description
I originally came across this during RQG Replication testing for MDEV-16329, but I think this is more an issue with the Aria engine rather than Replication. In the test case below, rpl_end.inc will time out because the slave SQL thread has stopped with the 1062 error as it cannot execute the ALTER statement that was successful on the primary.
With MyISAM and InnoDB, the ALTER TABLE is not allowed on the primary with ER_DUP_ENTRY (1062). If the CREATE TABLE statement defines the key as UNIQUE, then ER_DUP_ENTRY (1062) will occur upon INSERT with the Aria engine.
--source include/master-slave.inc

--source include/have_aria.inc
|
 |
--connection master
|
USE test; |
# No replication error with MyISAM and InnoDB |
# Need ROW_FORMAT DYNAMIC for replication error |
CREATE TABLE t9 (`col_int_nokey` SMALLINT UNSIGNED DEFAULT 0 ) ROW_FORMAT DYNAMIC ENGINE=Aria; |
LOCK TABLE t9 WRITE; |
INSERT INTO t9 () VALUES (),(),(); |
FLUSH TABLES;
|
ALTER TABLE t9 ADD UNIQUE (`col_int_nokey`), ALGORITHM=COPY; |
# or fails with the following in bb-11.0-oalter (1d16113) |
# ALTER ONLINE TABLE t9 ADD UNIQUE (`col_int_nokey`); |
--connection slave
|
--connection master
|
DROP table t9; |
--source include/rpl_end.inc |
Last_SQL_Errno 1062
|
Last_SQL_Error Error 'Duplicate entry '0' for key 'col_int_nokey'' on query. Default database: 'test'. Query: 'ALTER TABLE t9 ADD UNIQUE (`col_int_nokey`), ALGORITHM=COPY'
|
...
|
Wrong value for Last_SQL_Errno. Expected '0', got '1062'
|
MDEV-18745 looked similar based on the queries.
