Bug Description

Seen in stable/newton.

The DRAC driver's (pxe_drac) get_bios_config() vendor passthru method raises an AttributeError exception. It no longer returns the current BIOS configuration. This is a regression from stable/mitaka.

Triage found that get_bios_config() mistakenly treats the value returned by python-dracclient's list_bios_settings() as containing named tuples. When it calls the namedtuple _asdict() method, an AttributeError exception is raised.

It shows up in the ironic-conductor.log as:

    DRAC get_bios_config() passthru causes exception

    The DRAC driver's (pxe_drac) get_bios_config() vendor passthru method
    raises an AttributeError exception. It no longer returns the current
    BIOS configuration. This is a regression from stable/mitaka.

    Triage found that get_bios_config() mistakenly treats the value returned

    Revert get_bios_config()'s handling of the return value to use __dict__.
    Remove the comment that is not consistent with the implementation.

    Also revert the unit test case for a successful call to use mock to
    create the return value. Use mock.NonCallableMock with an empty
    specification (spec) to catch this type of bug in the future.

Hello Ubuntu guys.

It's already more than 4 months since Ironic 6.2.2 has been released. xenial-updates/newton/main still uses 1:6.2.1-0ubuntu1, and it still has that bug.

Are you really provide updates for cloud-archive for xenial, or not?

Hi George

I'd be happy to provide and update to ironic 6.2.2 however the ubuntu-openstack team don't have any capability to test ironic updates; if you'd be happy to handle the SRU testing requirements to ensure we don't hit any regressions then we can take a look at an update.

Cheers

James

(for future reference this is normally the case for an openstack package that resides in Ubuntu universe - once a package has been promoted to Ubuntu main, then the ubuntu-openstack team will have put in place the deployment and testing procedures to handled this type of update as part of business as usual).
