Description

Assertion `mode == 16 || mode == 12 || !fix_block->page.file_page_was_freed' failed in buf_page_get_low

It looks like all previous bugs with this assertion failure are closed at the moment.

I'm not sure whether the problem is really versioning-specific, but I couldn't get rid of versioning in the test case.

--source include/have_innodb.inc

CREATE TABLE t1 (

    pk INT PRIMARY KEY,

    f1 INT,

    f2 INT,

    f3 TEXT,

    KEY(f1),

    FULLTEXT(f3),

    KEY(f3(10)),

    FOREIGN KEY (f2) REFERENCES t1 (f1) ON DELETE SET NULL

) ENGINE=InnoDB WITH SYSTEM VERSIONING;

INSERT INTO t1 VALUES (1,8,8,'a'), (2,8,8,REPEAT('b',8071));

--error ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO

DELETE FROM t1;

SELECT * FROM t1;

# Cleanup

DROP TABLE t1;

Reproducible on 10.3+.
The test case is not applicable to earlier versions due to system versioning.

Non-debug builds produce the same ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO upon DELETE (I'm not sure whether it's legit), but no crash.

The test case is not applicable to earlier versions due to system versioning. Non-debug builds produce the same ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO upon DELETE (I'm not sure whether it's legit), but no crash.

Please note that the test case in the description uses an explicit primary key because I was told it makes bugs easier to investigate; but the failure is not only reproducible before the primary key, but also it seems far more obvious that the error on DELETE is already wrong – since there are no unique keys (defined by the user), there should be no duplicate key errors.

Test case without PK

CREATE TABLE t1 (
f1 INT,
f2 INT,
f3 TEXT,
KEY(f1),
FULLTEXT(f3),

FOREIGN KEY (f2) REFERENCES t1 (f1) ON DELETE SET NULL
) ENGINE=InnoDB WITH SYSTEM VERSIONING;
INSERT INTO t1 VALUES (8,8,'a'), (8,8,REPEAT('b',8071));

--error ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO

# Cleanup

It was previously filed as ~~MDEV-21137~~ and closed as a duplicate of ~~MDEV-21138~~ without fixing ~~MDEV-21138~~ and verifying that it covers both cases, and even without adding the alternative failure and test case to the bug report. Please don't do it with this one.

A slightly different test case, yet another completely different assertion failure. Again, don't discard it until it's been verified that the same fix fixes all of them, and add a test case for every variation of the failure.

Non-debug build doesn't crash, but it produces an unexpected error upon DELETE:

Elena Stepanova added a comment - 2020-09-01 22:51 A slightly different test case, yet another completely different assertion failure.

Because this involves system versioning, I think that this belongs to midenok, who is the assignee of ~~MDEV-21137~~ and ~~MDEV-21138~~.

{noformat}

Reproducible on 10.3+.
The test case is not applicable to earlier versions due to system versioning.

Non-debug builds produce the same ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO upon DELETE (I'm not sure whether it's legit), but no crash.

h3. Assertion `mode == 16 || mode == 12 || !fix_block->page.file_page_was_freed' failed in buf_page_get_low

_It looks like all previous bugs with this assertion failure are closed at the moment._

_I'm not sure whether the problem is really versioning-specific, but I couldn't get rid of versioning in the test case._

Reproducible on 10.3+.
The test case is not applicable to earlier versions due to system versioning.

Non-debug builds produce the same ER_FOREIGN_DUPLICATE_KEY_WITH_CHILD_INFO upon DELETE (I'm not sure whether it's legit), but no crash.
