            Bug ID: 1245425
           Summary: IFS is not set back after used as "[" in log_newer
                    function of include.rc
           Product: GlusterFS
           Version: mainline
         Component: tests
          Assignee: bugs at gluster.org

Description of problem:

In log_newer function, IFS is set to "[". It should be set back before the
function return. This causes the last cleanup in basic/afr/self-heald.t to
create a diretory "/d/backends\ /mnt/glusterfs/0\ /mnt/glusterfs/1\
/mnt/glusterfs/2\ /mnt/nfs/0\ /mnt/nfs/1/".

The following is part of the log file. The bash shell add single quotes to the
variable WORKDIRS

+ umount -l /mnt/nfs/1
+ umount -f /mnt/nfs/1
+ true
+ rm -rf '/d/backends /mnt/glusterfs/0 /mnt/glusterfs/1 /mnt/glusterfs/2
/mnt/nfs/0 /mnt/nfs/1'
+ leftover=
+ for d in '$WORKDIRS'
+ test -d '/d/backends /mnt/glusterfs/0 /mnt/glusterfs/1 /mnt/glusterfs/2
/mnt/nfs/0 /mnt/nfs/1'
+ '[' x '!=' x ']'
+ mkdir -p '/d/backends /mnt/glusterfs/0 /mnt/glusterfs/1 /mnt/glusterfs/2
/mnt/nfs/0 /mnt/nfs/1'
+ return 0
+ exit


Version-Release number of selected component (if applicable):
