rsync parameter return error with 2.3.2 build

[Maxim]

After latest update xtrabackup to 2.3.2 my backup scripts stop working.
Problem in "--rsync" argument. With it in half of "copying X to Y" xtrabackup exit with error message:
~~
can't create file (null)/xtrabackup rsync files pass1
~~

With previous builds all was fine.
Problem command line:
~~
innobackupex --defaults-file=/etc/mysql/my.cnf --user=root --password=`cat /root/passwords/.mysql` --no-timestamp --throttle=40 --rsync /var/backups/separate_disk/mysql/${WEEK_DAY_NUMBER}f 2>&1
~~

If remove "--rsync" - all work without errors.

P.S. and previous versions uses "root" as default user name. Now it use "mysql" if in command line didn't defined "--user". (Back incompatibility)

Would specifying --tmpdir=/tmp (or other directory) resolve the rsync issue?

[Maxim (sailormax)]

yes.

[Sergei Glushchenko (sergei.glushchenko)]

We'll set tmpdir to system/user default when it is not specified.
