- Start 10.1 server, all defaults are sufficient;
- create a table as
CREATE TABLE t1 (f1 INT, f2 INT AS (f1) VIRTUAL) ENGINE=InnoDB;
- shut down the server normally;
- start 10.3 or 10.4 server on the same datadir;
- (optionally, it doesn't affect the outcome) run mysql_upgrade;
CHECK TABLE t1;
ALTER TABLE t1 DROP CONSTRAINT IF EXISTS x;
The result is
Table Op Msg_type Msg_text
test.t1 check status OK
ERROR 1932 (42S02) at line 2: Table 'test.t1' doesn't exist in engine
The error log gets the warning:
2019-05-27 1:49:53 9 [Warning] InnoDB: Table test/t1 contains 1 user defined columns in InnoDB, but 2 columns in MariaDB. Please check INFORMATION_SCHEMA.INNODB_SYS_COLUMNS and https://mariadb.com/kb/en/innodb-data-dictionary-troubleshooting/ for how to resolve the issue.
Further attempts to use the table cause errors in the log:
2019-05-27 1:50:18 10 [ERROR] InnoDB: Table `test`.`t1` is corrupted. Please drop the table and recreate.
A datadir pre-created as described on 10.1 aaf53ea0 is attached.
Not reproducible with 10.2, either being the new server or old server in the scenario.
