Hi, guys,
We have agreement on how to deprecate the CLI for the proxy APIs which
were deprecated in 2.36 when mid-cycle. But I still feels that we have
something isn't very clear. So I just want to summary the situation at
here, and to be clear the final goal.
Here are the patches https://review.openstack.org/347514
and https://review.openstack.org/#/c/348499
So the agreement is:
When user executes the network related CLI without specific version or
with specific version > 2.35, the CLI will fallback to 2.35 automatically.
For the API part, we won't do any workaround, so that means we will stop
to support those after 2.35, we need add decorator like
this
https://github.com/openstack/python-novaclient/blob/master/novaclient/v2/servers.py#L917
I hadn't considered capping the python APIs in novaclient like this, but
it was something I was wondering about. The image and baremetal CLI/APIs
in novaclient have already been deprecated, but we don't cap those in
the API, nor do we try and make it a soft landing for the CLIs. The only
reason the network stuff gets a temporary pass on the CLI side is for
nova-network users.
That's also because the CLI defaults to 2.latest, the API doesn't. So
for the API you have to opt into use newer versions, right? If that's
the case, then you would need to consciously request 2.36 on those proxy
APIs for them to fail, which I'm hoping people aren't going to be doing,
or at least they should be reading the REST API version history first to
see what they are opting into.
But the agreement is only talk about network related thing, we also
deprecate image/volume/snapshot/baremetal/fping stuff. So what is the
plan for them? I guess we just no workaround also, stop the support
after 2.35.
So the final status will be as below:
* Network CLI: Auto fallback to 2.35 in the patch
* Quota/Limit CLI: Remove network quotas after 2.35 in the current patch
* Image CLI: Currently the CLI emit the deprecated message in the code,
but it still break in 2.36(get a 404 message). We should stop support it
after 2.35
* Baremetal CLI: Same as Image CLI, there is message, but will break in
2.36. Stop to support it after 2.35
* No Volume/Snapshot/fping related CLI
* Network/Image/Quota/Limit/Baremetal/Volumes/fping API: No workaround.
Stop to support them after 2.35.
Thanks
Alex
