** Changed in: mysql-5.5 (Ubuntu Utopic)
Status: New => In Progress
** Description changed:
I've verified that the following MariaDB issue also impacts MySQL:
- https://mariadb.atlassian.net/browse/MDEV-6615
-
+ https://mariadb.atlassian.net/browse/MDEV-6615
[Impact]
- Data corruption on arm64 (and maybe ppc64el?)
+ Data corruption on arm64 and ppc64el
[Test Case]
Reproducibility varies across SoCs but, at least on one SoC, it reliably
fails within seconds with these sysbench commands:
sysbench --num-threads=128 --max-requests=0 --max-time=1000 --test=oltp
prepare
sysbench --num-threads=128 --max-requests=0 --max-time=1000 --test=oltp run
On failure, mysql will crash and sysbench will report a connection loss
to the database.
[Regression Risk]
The fix touch some low level locking code, so there is always the risk that
it introduces a problem on other platforms. However, this fix has been included
in MariaDB since the 10.0.13 release in Aug, 2014 so it has had some real world
testing.
** Summary changed:
- data corruption on arm64
+ data corruption on arm64 and ppc64el
