The test below mostly hits error 192, like in 90% cases; error 126 or error 22 (for which this report is devoted) are more rare.
Error 22 is currently best reproducible on 10.2, but it has been observed on all 10.2+ versions.
To run the test:
git clone https://github.com/MariaDB/randgen --branch mdev19980 rqg-mdev19980
|
cd rqg-mdev19980
|
. ./mdev19980.cmd <your basedir> <your vardir>
|
Important note: The command above will re-run the same test 10 times, regardless the outcome, and for each failure it will create <your vardir>_trialX directory, which you can later inspect. If you want it to stop on first failure, remove -force from the command line inside mdev19980.cmd, but keep in mind the note above, that error 22 represents the minority of failures.
I think that using on-disk vardir location gives better chances for reproducing (any of the errors), but it's unproved, I don't have statistics for this.
