    Support `truncated` flag returned by keystone

    Wrap a list of objects into custom class with additional attributes.

    This is wanted by Horizon, that wants to know that the list returned
    from keystone is not full and that more strict filters need to be
    applied.

This issue was fixed in the openstack/python-keystoneclient 2.1.0 release.

I am re-opening this bug to the confirmed state, as it broke the keystone gate for stable/liberty.

It was failing these tests: https://github.com/openstack/keystone/blob/stable/liberty/keystone/tests/unit/test_v2_keystoneclient.py#L1187-L1202

Since it's very possible that other folks were also doing a similar check, we have decided to revert the change and release a new version of keystoneclient.

    Support `truncated` flag returned by identity service

    Create a custom list with flag `truncated` to support corresponding
    response from the identity service.

    This is wanted by Horizon, that wants to know that the list returned
    from keystone is not full and that more strict filters need to be
    applied.

    The previous attempt in commit c28d40814962b3a8ccb81e5e7d7f832c8f0a3c9a
    was reverted by d20b300589863bcf165945beb129ebcc3621a14f because it
    broke other code. This commit changes the way the flag is added and
    verifies that existing code will not break.

Reason: i agree

Automatically unassigning due to inactivity.

We should move this work to SDK and not enhance keystoneclient. Marking as wont fix due to age.
