Sorry I wiped the database; but it got to the point where MariaDB
immediately crashed upon startup (so the usual repair attempts were futile,
as they all kinda assume a MariaDB server that's up and running). I have
years of experience (FreeBSD) with myisam tables; but a crash like this is a
first for me, really, where the entire database was foobarred to the point
MariaDB wouldn't even start any more.

 

Thanks for creating the bug report. I shall investigate myself too, in
trying to find a way to integrate the MariaDB shutdown gracefully (in UNIX
this is all much simpler and straightforward).

Yes, it is possible that Windows does not give enough time to MariaDB to
shut down gracefully. I just created a task for this one here
https://jira.mariadb.org/browse/MDEV-10183.

Still, Innodb should handle this situation gracefully, and recover on
startup, so what you see is a bug. It is a pity that you wiped down the
database, it would be useful for a bug report.

database).

 

So, my question is, what could cause MariaDB to fail so horrendeously?! I
though InnoDB was supposed to be *better* than myisam!? Is is because maybe
Windows 10 doesn't give MariaDB enough time to shut down gracefully? Could
it be because a Windows scheduler job (potentially) aborts the fetcher
script when it's still running? (Again, I though InnoDB was supposed to be
transaction-safe).

 

In its current state, MariaDB is completely unusable for me.

 

And no, I don't have hard disk errors. :)

 

Seriously, though, I could use some major insight!

 

Thanks.

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.
