Description

Note: The test case is non-deterministic, run with --repeat=N. Currently it fails for me on within a few attempts on a debug build, but it can vary on different machines and builds. Couldn't get it on a release build even within 2000 attempts (not sure whether it is due to a different timing or a different logic).

CREATE TABLE table_1 ( f1 VARCHAR(32) CHARACTER SET utf8 NOT NULL, KEY (f1) USING HASH) ENGINE=HEAP;

INSERT INTO table_1 VALUES (''),(''),(''),(''),(''),(''),(''),('');

INSERT INTO table_1 SELECT * FROM table_1;

INSERT INTO table_1 SELECT * FROM table_1;

INSERT INTO table_1 SELECT * FROM table_1;

SET lock_wait_timeout= 1;

LOCK TABLES table_1 WRITE CONCURRENT;

--connect (con1,localhost,root,,test)

SET lock_wait_timeout= 1;

--send

  DELETE FROM table_1 WHERE f1 < 'bar';

--connection default

--error 0,ER_LOCK_WAIT_TIMEOUT

LOCK TABLE table_1 READ NOWAIT;

# Cleanup

--connection con1

--error 0,ER_LOCK_WAIT_TIMEOUT

--reap

--disconnect con1

--connection default

UNLOCK TABLES;

DROP TABLE table_1;

CURRENT_TEST: bug.5348a
mysqltest: At line 17: query 'LOCK TABLE table_1 READ NOWAIT' failed with wrong errno 1034: 'Index for table 'table_1' is corrupt; try to repair it', instead of 0...

Reproducible on 10.3-10.5.
The test case is not applicable to earlier versions due to the use of NOWAIT, and I couldn't get rid of it. It's possible however that the underlying cause exists in other versions as well.

In a similar test case, which also produces ER_NOT_KEYFILE, if we take it a little further and allow the error, various ASAN errors happen on an ASAN build.
The test case is to be run with --repeat=N --nowarnings.

CREATE TABLE t1 ( f1 VARCHAR(32), f2 VARCHAR(128), KEY(f2) USING BTREE ) ENGINE=HEAP;

INSERT IGNORE INTO t1 VALUES ('',''),('', 'g'),('l', ''),( 'p', 'x' ),('','');

INSERT INTO t1 SELECT * FROM t1;

INSERT INTO t1 SELECT * FROM t1;

INSERT INTO t1 SELECT * FROM t1;

INSERT INTO t1 SELECT * FROM t1;

LOCK TABLES t1 n WRITE CONCURRENT WAIT 1;

--connect (con1,localhost,root,,test)

--send

DELETE FROM t1 WHERE f1 < 'bar';

--connection default

--error 0,ER_NOT_KEYFILE,ER_LOCK_WAIT_TIMEOUT

LOCK TABLE t1 READ NOWAIT;

# Cleanup

--connection con1

--reap

--disconnect con1

--connection default

UNLOCK TABLES;

DROP TABLE t1;
