[MDEV-23916] Regression: 10.4 and 10.5 mysqld fails to start on sparc64, segfaults on sing host libthread_db library Created: 2020-10-08  Updated: 2021-04-29

Status: Open
Project: MariaDB Server
Component/s: None
Affects Version/s: 10.4.13, 10.5.6
Fix Version/s: None

Type: Bug Priority: Major
Reporter: Otto Kekäläinen Assignee: Unassigned
Resolution: Unresolved Votes: 0
Labels: None


 Description   

MariaDB 10.3 builds and runs OK on sparc64, see example https://buildd.debian.org/status/fetch.php?pkg=mariadb-10.3&arch=sparc64&ver=1%3A10.3.24-1&stamp=1598110080&raw=0

Unfortunately in 10.4 (and 10.5) it has regressed. While it does build, the mysqld daemon immediately segfaults when started.

main.sp_trans_log 'innodb'               w1 [ fail ]

Output from gdb follows. The first stack trace is from the failing thread.
 
The following stack traces are from all threads (so the failing one is
 
duplicated).

mysqltest failed but provided no output

Example logs:

All logs of 10.4 and 10.5 ever tested in Debian has this same phenomenon and can be browsed at:

NOTE! The test suite result has been supressed, so builds show "passed" even though MTR failed and mysqld segfaulted. One has to open the logs above to evaluate the MTR status.

brad0 has sent patches on sparc64 before - maybe you can help testing and fixing this one?

otto, one major difference between 10.3 and 10.4 that might be related to this is the move to C++11, and the use of std::atomic for everything in InnoDB.

Could you submit a special build that would disable InnoDB altogether?

And another that would run ./mtr with --suite=innodb --force instead of running the default suites and stopping on the first failure? That should allow us to narrow down the problem.

I filed this downstream in Debian as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972059 in case some Sparc experts from Debian could help out.

Somebody who has better time to research this could also reach out to the various porter IRC channels and ask for help in debugging/testing, see https://wiki.debian.org/Ports -> https://wiki.debian.org/Sparc64 -> debian-sparc@lists.debian.org and irc://irc.debian.org/debian-sparc and irc://irc.debian.org/debian-ports

Hi Otto,

I had noticed this bug report in the past but forgot to reply. I am fairly certain things are good with MariaDB on OpenBSD/sparc64, but I will see about having
the test suite run to see if there is anything obvious. We are currently using 10.5.
