Description

Note: From the test logic, I assume these tests are meant to run with master and slave operating on the same S3 storage. If it's configured to use separate storages, the tests fail too, just differently.

s3.replication_mixed 'mix' [ fail ]
Test ended at 2020-09-20 17:00:15

CURRENT_TEST: s3.replication_mixed
analyze: sync_with_master
mysqltest: In included file "/data/bld/10.5-s3/mysql-test/suite/s3/replication.inc":
included from /data/bld/10.5-s3/mysql-test/suite/s3/replication_mixed.test at line 12:
At line 35: sync_slave_with_master failed: 'select master_pos_wait('master-bin.000001', 1365, 300, '')' returned NULL indicating slave SQL thread failure

The result from queries just before the failure was:
< snip >
#
# Test ALTER TABLE ENGINE S3
#
create table t1 (a int, b int) engine=aria;
insert into t1 select seq,seq+10 from seq_1_to_10;
alter table t1 engine=s3;
show create table t1;
Table Create Table
t1 CREATE TABLE `t1` (
`a` int(11) DEFAULT NULL,
`b` int(11) DEFAULT NULL
) ENGINE=S3 DEFAULT CHARSET=latin1 PAGE_CHECKSUM=1
connection slave;
use database;
select * from t1 limit 2;
a b

2 12
connection master;
alter table t1 add column c int;

More results from queries before failure can be found in /data/bld/10.5-s3/mysql-test/var/log/replication_mixed.log
