During our “Graduation Schedule” summit session we worked through the list of 
modules remaining the in the incubator. Our notes are in the etherpad [1], but as 
part of the "Write it Down” theme for Oslo this cycle I am also posting a 
summary of the outcome here on the mailing list for wider distribution. Let me know 
if you remembered the outcome for any of these modules differently than what I have

Deleted or deprecated modules:

funcutils.py - This was present only for python 2.6 support, but it is no 
longer used in the applications. We are keeping it in the stable/juno branch of 
the incubator, and removing it from master (https://review.openstack.org/130092)

hooks.py - This is not being used anywhere, so we are removing it. 
(https://review.openstack.org/#/c/125781/)

quota.py - A new quota management system is being created 
(https://etherpad.openstack.org/p/kilo-oslo-common-quota-library) and should 
replace this, so we will keep it in the incubator for now but deprecate it.

crypto/utils.py - We agreed to mark this as deprecated and encourage the use of 
Barbican or cryptography.py (https://review.openstack.org/134020)

cache/ - Morgan is going to be working on a new oslo.cache library as a 
front-end for dogpile, so this is also deprecated 
(https://review.openstack.org/134021)

apiclient/ - With the SDK project picking up steam, we felt it was safe to 
deprecate this code as well (https://review.openstack.org/134024).

xmlutils.py - This module was used to provide a security fix for some XML 
modules that have since been updated directly. It was removed. 
(https://review.openstack.org/#/c/125021/)



Graduating:

oslo.context:
- Dims is driving this
- https://blueprints.launchpad.net/oslo-incubator/+spec/graduate-oslo-context
- includes:
        context.py

oslo.service:
- Sachi is driving this
- https://blueprints.launchpad.net/oslo-incubator/+spec/graduate-oslo-service
- includes:
        eventlet_backdoor.py
        loopingcall.py
        periodic_task.py
By te way, right now I'm looking into updating this code to be able to run 
tasks on a thread pool, not only in one thread (quite a problem for Ironic). 
Does it somehow interfere with the graduation? Any deadlines or something?

Feature development on code declared ready for graduation is basically frozen 
until the new library is created. You should plan on doing that work in the new 
oslo.service repository, which should be showing up soon. And the you describe 
feature sounds like something for which we would want a spec written, so please 
consider filing one when you have some of the details worked out.
Sure, right now I'm experimenting in Ironic tree to figure out how it really works. There's a single oslo-specs repo for the whole oslo, right?



        request_utils.py
        service.py
        sslutils.py
        systemd.py
        threadgroup.py

oslo.utils:
- We need to look into how to preserve the git history as we import these 
modules.
- includes:
        fileutils.py
        versionutils.py



Remaining untouched:

scheduler/ - Gantt probably makes this code obsolete, but it isn’t clear 
whether Gantt has enough traction yet so we will hold onto these in the 
incubator for at least another cycle.

report/ - There’s interest in creating an oslo.reports library containing this 
code, but we haven’t had time to coordinate with Solly about doing that.



Other work:

We will continue the work on oslo.concurrency and oslo.log that we started 
during Juno.
