MySQL Bugs: #93683: Got error 155 when reading table './test/t1'

Bug #93683	Got error 155 when reading table './test/t1'
Submitted:	19 Dec 2018 11:17	Modified:	29 Jul 2019 9:25
Reporter:	Roel Van de Paar	Email Updates:

Category:	MySQL Server: InnoDB storage engine	Severity:	S1 (Critical)
Version:	8.0.13	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
This may or may not be a bug, but I wanted to log it in any case, for analysis

8.0.13>ALTER TABLE t1 DISCARD TABLESPACE;
Query OK, 0 rows affected (0.07 sec)

8.0.13>SELECT COUNT(*)FROM t1;
ERROR 1814 (HY000): Tablespace has been discarded for table 't1'

This ERROR seems justified. However this is in the error log;

2018-12-19T11:07:33.878962Z 9 [ERROR] [MY-010211] [Server] Got error 155 when reading table './test/t1'

An unclear error. Why would the error log not report the same as the client, if anything?

How to repeat:
CREATE DATABASE test;
USE test;
CREATE TABLE t1(a INT KEY,b CHAR (1),c CHAR(1));
ALTER TABLE t1 DISCARD TABLESPACE;
SELECT COUNT(*)FROM t1;

Thank you for the bug report.
