|
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.
|
|
|
Server version: 10.4.22-MariaDB-debug-log
|
key_buffer_size=1048576
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=153
|
thread_count=6
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63649 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went

terribly wrong...

gcol.innodb_virtual_basic was disabled for long due to being marked as big-test, so it was much likely skipped before.

While I was trying to reproduce the issue, I've caught ut_ad(mysql_table) in innobase_init_vc_templ.
What I did is, I've added usleep(random() % 200); in the beginning of innodb_acquire_mdl
and run the following snip from innodb_virtual_basic.test:
--let $i= 1
|
--while ($i) {
|
--echo ========================== $i =========================================
|
--inc $i
|
CREATE TABLE t (a INT, b INT, c INT GENERATED ALWAYS AS(a+b), h VARCHAR(10), j INT, m INT GENERATED ALWAYS AS(b + j), n VARCHAR(10), p VARCHAR(20) GENERATED ALWAYS AS(CONCAT(n, h)), INDEX idx1(c), INDEX idx2 (m), INDEX idx3(p)); |
INSERT INTO t VALUES(11, 22, DEFAULT, "AAA", 8, DEFAULT, "XXX", DEFAULT); |
INSERT INTO t VALUES(1, 2, DEFAULT, "uuu", 9, DEFAULT, "uu", DEFAULT); |
INSERT INTO t VALUES(3, 4, DEFAULT, "uooo", 1, DEFAULT, "umm", DEFAULT); |
SELECT c FROM t; |
SELECT m FROM t; |
SELECT p FROM t; |
SELECT * FROM t; |
update t set a = 13 where a =11; |
delete from t where a =13; |
DROP INDEX idx1 ON t; |
DROP INDEX idx2 ON t; |
DROP TABLE t; |
--} |
This happens when the server is in progress of mysql_inplace_alter_table, around mysql_rename_table

marko please review commits a6efb30e...f66b5064,
branch bb-10.4-nikita
I will also have to merge it down to 10.3, but let's first start from review.
I think that thiru can do a first review.
I understood that this does not affect 10.5 or later versions, thanks to MDEV-16678. All test failures that I could find for 10.5 or 10.6 were for something unrelated in a MemorySanitizer build, which were since then fixed.
The final commit message should say that this is based on MDEV-16678. I would like to see a test run based on the latest 10.3 and 10.4 branches before the final approval.
nikitamalyavin, what is the status of this? If this is only targeting 10.3 and 10.4, why do the fix versions include 10.5 and 10.6?
If this is not changing anything in 10.5 or 10.6, then I suppose that the the following, which I just got in a local AddressSanitizer build, would not be fixed by this? The issue is repeatable for my build, so I reran it with ASAN_OPTIONS=fast_unwind_on_malloc=0 to get a useful stack trace for the allocation:

With ./mtr --rr you should even get a stack trace of the poisoning. It worked for me. It looks like a buffer overflow:

We allocated 7 bytes (which the ASAN instrumentation expands to 15), and the read will be reported for byte offset 7 (1 byte after the allocated buffer).
Also, could this ticket be duplicating MDEV-16950 in any way?
There are also MSAN failures on 10.6 with similar stack traces. It would make sense that the out-of-bounds location may contain an uninitialized value.

Sorry, I realized that the recent failure is due to my MDEV-29438. I will fix it in MDEV-29471.
We got SIGSEGV on 10.4 as well. Probably an issue with missing or incorrect MDL protection? Note:
MDEV-25506in 10.6 introduced dict_table_t::mdl_name that might fix this, by making a user-visible table name available also during DDL operations.10.4 b53ee760ff17e3d9ed95b75e5ea2de124ae69384
