 Description   

The attached testcase (fk.sql), can sporadically generate all sorts of issues in the server like crashes (sig 11 in opt), hangs (mysqld + client), inability to automatically create a core file even though error log shows 'mysqld got signal 11', inability to report stack in error log.

The testcase is simple (2 lines only) but the second query is very with FK references. Condensed version (as example of what happens only; not for actual use/replay);

USE test;
 
CREATE TABLE  t1  ( `a` int(11) DEFAULT NULL, KEY `a` (`a`), 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa1` 
  FOREIGN KEY (`a`) REFERENCES `bug56143_1` (`a`) ON UPDATE SET NULL, 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa10` 
  FOREIGN KEY (`a`) REFERENCES `bug56143_1` (`a`) ON UPDATE SET NULL, 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa100` 
...etc...
 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa97` 
  FOREIGN KEY (`a`) REFERENCES `bug56143_1` (`a`) ON UPDATE SET NULL, 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa98` 
  FOREIGN KEY (`a`) REFERENCES `bug56143_1` (`a`) ON UPDATE SET NULL, 
CONSTRAINT `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa99` 
  FOREIGN KEY (`a`) REFERENCES `bug56143_1` (`a`) ON UPDATE SET NULL );

I believe the bug affects 10.1-10.4 opt + dbg from what I have seen thus far, and may affect 10.5 also, though this is not confirmed. The testcase may have to be repeated many times, and it could be that machine load affects the reproducibility (with high load being better).

An example sig11 crash on 10.3.25 optimized:

This could be because you hit a bug. It is also possible that this binary
 
or one of the libraries it was linked against is corrupt, improperly built,
 
or misconfigured. This error can also be caused by malfunctioning hardware.
 
 
 
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
 
 
 
We will try our best to scrape up some info that will hopefully help
 
diagnose the problem, but since we have already crashed,
 
something is definitely wrong and this may fail.

read_buffer_size=131072
 
max_used_connections=1
 
max_threads=153
 
thread_count=7
 
It is possible that mysqld could use up to
 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467424 K  bytes of memory
 
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
 
where mysqld died. If you see no messages after this, something went
 
terribly wrong...

Repeating the testcase a number of times has shown the server to hang more easily.

Comment by Roel Van de Paar [ 2020-08-13 ]

Inserting this into the testcase:

CREATE TABLE bug56143_1 (a INT);

Makes the testcase more reliably crashable it seems, especially when repeated twice.

Comment by Roel Van de Paar [ 2020-08-13 ]

With the modifications specified in the last comment, and uploaded as fk2.sql, the outcome is:

Bug confirmed present in:
MariaDB: 10.1.47 (dbg), 10.1.47 (opt), 10.2.34 (dbg), 10.2.34 (opt), 10.3.25 (dbg), 10.3.25 (opt), 10.4.15 (dbg), 10.4.15 (opt)

Bug confirmed not present in:
MariaDB: 10.5.6 (dbg), 10.5.6 (opt)
MySQL: 5.5.62 (dbg), 5.5.62 (opt), 5.6.47 (dbg), 5.6.47 (opt), 5.7.29 (dbg), 5.7.29 (opt), 8.0.19 (dbg), 8.0.19 (opt)

Producing the crash on a debug build of 10.4.15 specifically required executing fk2.sql multiple times (4-5) in succession. Even 30-40+ repeats did not crash 10.5 in any way.

Comment by Aleksey Midenkov [ 2020-08-24 ]

Lowering the priority as the use case probably will never be the real world. Also high chance it is superseded by MDEV-16417.
