nova.bash_completion can not complete when the name include whitespace

[Ikuo Kumagai]

tools/nova.bash_completion take the string for completion from

tools/nova.bash_completion#L19-21
---
                COMPLETION_CACHE=~/.novaclient/*/*-cache
                cflags="$_nova_flags "$(cat $COMPLETION_CACHE 2> /dev/null | tr '\n' ' ')
                COMPREPLY=($(compgen -W "${cflags}" -- ${cur}))
---

This logic just read the cache file and pass to "compgen".
Therefore the name separated by whitespace is treated as distributed items.
It should be treated as isolated item by each lines.

Hello Ikuo,

This is regarding nova client bashcompletion bug
https://bugs.launchpad.net/python-novaclient/+bug/1395029
I am owning.

I would request a bit more clarity from you on this bug.

I have not experience bash completion with nova commands
So may be I am missing some silly thing, kindly help.

This is my cache directory
/home/stack/.novaclient/21232f297a57a5a743894a0e4a801fc3

stack@ubuntu14-OptiPlex-3020:~/.novaclient/21232f297a57a5a743894a0e4a801fc3$ ls
cloudpipe-human-id-cache flavor-uuid-cache image-human-id-cache keypair-uuid-cache server-human-id-cache volume-uuid-cache
cloudpipe-uuid-cache hypervisor-human-id-cache image-uuid-cache migration-human-id-cache server-uuid-cache
flavor-human-id-cache hypervisor-uuid-cache keypair-human-id-cache migration-uuid-cache volume-human-id-cache
stack@ubuntu14-OptiPlex-3020:~/.novaclient/21232f297a57a5a743894a0e4a801fc3$

ALL my cache files are empty and do not have any value cached.

My Doubt is :
How to generate cache files content, some setting some flag for this ?
How to experience bash completion in novaclient ?
I mean I want to reproduce this bug how to do that ?
Can you please suggest ?

Thanks
Nidhi
