Openstack image list should sort on name

[Vijendra Soni]

Currently openstack image list display output sorted on the sort_key as 'created_at" argument(taken by default) and sort_dir as desc. For example:
openstack image list
+--------------------------------------+---------------------------------+--------+
| ID | Name | Status |
+--------------------------------------+---------------------------------+--------+
| 44a15e58-b9b4-4e94-8b19-33837b0f1657 | cirros-0.3.4-x86_64-uec | active |
| 2c74ff4c-7baa-42f9-afe0-6b620bf79a90 | cirros-0.3.4-x86_64-uec-ramdisk | active |
| 7850eb88-ec7e-40f4-b72d-0a812e2960b1 | cirros-0.3.4-x86_64-uec-kernel | active |
+--------------------------------------+---------------------------------+--------+

However glance image-list do it differently. sort_key as 'name' and sort_dir as 'asc'. For example:

glance image-list
+--------------------------------------+---------------------------------+
| ID | Name |
+--------------------------------------+---------------------------------+
| 44a15e58-b9b4-4e94-8b19-33837b0f1657 | cirros-0.3.4-x86_64-uec |
| 7850eb88-ec7e-40f4-b72d-0a812e2960b1 | cirros-0.3.4-x86_64-uec-kernel |
| 2c74ff4c-7baa-42f9-afe0-6b620bf79a90 | cirros-0.3.4-x86_64-uec-ramdisk |
+--------------------------------------+---------------------------------+

It make more sense to sort the output based on 'name' as it is more human friendly output. So need to change the default sort_key to 'name' and sort_dir to 'asc'

Dear Reviewers,

I would like to share earlier bug filed in the glance to address the similar issue, this time I am trying to fix the same for openstack client.

URL : https://bugs.launchpad.net/python-glanceclient/+bug/1081542.

Thanks

We cannot change the default sort values or direction.

There are filtering options available for the image-list call that can be used to customize the output; those should be used instead.

[Brian Rosmaita (brian-rosmaita)]

I just realized this is an OSC bug, not a Glance bug. The OSC people may have a different opinion on what they want to do about this. But the above is my two cents.

[Steve Martinelli (stevemar)]

We can sort this on the client side, anything we should know about when it comes to sorting massive lists? does glance use markers and such?

[Vijendra Soni (vijendra-soni)]

yes glance use marker along with limit,sort_key,sort_dir and filters.

however marker set to none for openstack image list without any further command argument and sort_key set to 'created_at' and sort_dir' set to 'desc'.

When issuing openstackstack image list --sort 'name:asc' , marker set to none, sort_key as 'name' and sort_dir as 'asc'.

please suggest how to go for default sort by name in asc order fix.

Thanks,
Vijendra Soni

Steve, one simple approach it to set the default for sort parameter if it is none(no command line argument passed). I replicated it in my local and giving as expected results.
