maas-cli listing nodes filtered by hostname doesn't work

[Geoff Teale]

When trying to scripting against maas-cli it's often necessary to acquire the system-id via a listing filtered by some other attribute. This works well with, for example mac_address:

    tealeg@vmaasserver:~$ maas-cli mymaas nodes list mac_address="AA:AA:AA:AA:AA:01" | grep system_id | cut -d \" -f4
    node-7757fbc4-4703-11e3-bd5a-aaaaaaaaaa00

.. but if I try to do the same thing with a hostname instead of MAC address I don't get the result I'd expect:

    tealeg@vmaasserver:~$ maas-cli mymaas nodes list hostname="client08.master" | grep system_id | cut -d \" -f4
    node-08dcf110-4701-11e3-bd5a-aaaaaaaaaa00
    node-73b6985e-4703-11e3-9381-aaaaaaaaaa00
    node-744e8326-4703-11e3-bd5a-aaaaaaaaaa00
    node-74cdaafc-4703-11e3-9381-aaaaaaaaaa00
    node-75585724-4703-11e3-bd5a-aaaaaaaaaa00
    node-75ccb51a-4703-11e3-9381-aaaaaaaaaa00
    node-76567c3c-4703-11e3-bd5a-aaaaaaaaaa00
    node-76c48c90-4703-11e3-9381-aaaaaaaaaa00
    node-7757fbc4-4703-11e3-bd5a-aaaaaaaaaa00

.. that is a listing of all nodes on my maas. I'd rather see a syntax error if filtering on hostname is not allowed, but better still it should work.

Hi all,

I have link a related branch that adds the capability of filtering by hostname to the list API call, which is really what's biting us at the moment.
Maybe we could defer the more general case of raising errors instead of returning unfiltered results to another bug?

[Chris Glass (tribaal)]

I take the liberty to change the description of this bug back to its original version, and will open a new bug for the general case

This happened to me today.

$ maas root nodes list | grep hostname
        "hostname": "usable-group.maas",
        "hostname": "eager-insurance.maas",
        "hostname": "funny-shape.maas",
        "hostname": "fast-hospital.maas",

$ maas root nodes list hostname=usable-group.maas
Success.
Machine-readable output follows:

maas root nodes list hostname=usable-group

You need to remove the ".maas" from the list query.
