sdfscli --file-info does not work on blank files. #23

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a volume with: mksdfs --volume-name=sdfs_vol2 --volume-capacity=1GB
2. mount the volume with: mountsdfs -v sdfs_vol2 -m K
3. Copy a blank file i.e. a 0 byte file over to the volume
4. Perform sdfscli --file-info --file-path="blank.txt"

What is the expected output? What do you see instead?
I would expect to see file details, however sdfscli simply hangs
the output from the mountsdfs command prompt is as follows:
