[webmin-l] MySQL dump in Webmin deletes directory if filename matches

[Alfredo A. <lic...@gm...>]

Hello to all.

In Webmin, I was going to dump a database called "proy7" to a file, so in
the "Backup database" screen I completed the complete path and name of file
where I wanted to dump that database. Somehow, I didn´t finish the name of
the file, and typed down only this:

/var/www/html/proyectos/proy7

Unfortunately, that's the exact name of the directory where I wanted to
dump the file. I pressed Enter without checking twice, but I though that
Webmin was going to tell me that he could not create that file, because it
was a directory. But to my surprise, the backup was made. And was shocked
to see that the directory had been deleted, remaining only the file with
the database backup.

I tried to do the same using the console, but as I expected, it didn't let
me dump the database to a file if the directory existed:

root@servername:/var/www/html/proyectos# mysqldump -u proyecto6 -p
proyecto6 > proy7
-bash: proy7: Es un directorio

(For those who do not know Spanish, it only says that proy7 is a directory)

Justo to be sure, I've tested all this again, and I confirm that if the
file name matches an existing directory name in the "Path on server" field,
the directory is deleted and replaced by the dump.

I have been extremely lucky because the web site was just a test, so
nothing important has been lost. And anyways, I have backups of course. But
I think that it would be a good idea if this could be corrected to avoid
certain level of panic fiding out that data can be deleted.

My system configuration is Debian 9.1, Webmin 1.850, and MariaDB 10.1.26.
Jamie, please tell me if you need further information.

Kind regards:

Alfredo
