innobackupex-1.5.1 gets wrong temp dir

[Christian Kaps]

In the latest 1.0 release there is an error in the innobackupex-1.5.1 script.

./innobackupex-1.5.1 --port 3306 --user=xtrabackup --password='*********' --stream=tar --defaults-file=/etc/my.cnf /var/lib/mysql | gzip - > /srv/mysql/backups/test.tar.gz

innobackupex: Error: Failed to stream 'backup-my.cnf': Inappropriate ioctl for device at ./innobackupex-1.5.1 line 452.

When I change the line 1558:

my $filename_dir = substr($filename, 0, rindex($filename, '/') - 1);

to:

my $filename_dir = substr($filename, 0, rindex($filename, '/'));

it works for me.

Greetings,

I managed to cause this error a different way: I was piping the output into gzip, but changed it to pigz (parallel gzip, makes a huge difference to backup speed), however, I'd failed to actually install pigz! innobackupex was thus piping the output into a non-existent program and it caused the same error as this. I don't know if it's reasonable to expect innobackupex to deal with that situation, but it did produce exactly the same error.
