Is it considered stable already?
It can't be considered stable. It is in alpha status at the moment.
Among the repos I checked, I found:
ovirt-engine-cli/ovirt-engine-cli.spec.in:Requires:
ovirt-engine-sdk-python >= 3.6.0.0
ovirt-hosted-engine-setup/ovirt-hosted-engine-setup.spec.in:Requires:
ovirt-engine-sdk-python >= 4.0.0.0
ovirt-image-uploader/ovirt-image-uploader.spec.in:Requires:
ovirt-engine-sdk-python >= 4.0.0.0
ovirt-iso-uploader/ovirt-iso-uploader.spec.in:Requires:
ovirt-engine-sdk-python >= 4.0.0.0
ovirt-log-collector/ovirt-log-collector.spec.in:Requires:
ovirt-engine-sdk-python3 >= 4.0.0.0
ovirt-log-collector/ovirt-log-collector.spec.in:Requires:
ovirt-engine-sdk-python >= 4.0.0.0
I guess -cli, the uploaders, and -collector can be considered
"not-urgent" and can simply wait until we fix them.
Main issue is that currently the engine requires the uploaders. We
recently re-removed log-collector req upstream, perhaps we can do that
with the uploaders too. Personally I do not think they are that
important, especially since 4.0 should have a web ui uploader at some
point.
hosted-engine-setup might be a bit more urgent, not sure.
All of them, I guess, use very little functionality of the engine/sdk
and can probably be ported to the new sdk quite easily, if it's
considered stable.
Not sure how to use 3.6 sdk - we can patch all of them to require >=
3.6 and add it to the -snapshot-static repo, and/or tell people to add
the 3.6 repos when they want master (not healthy imo, because we do
want to know if someone has to use something from 3.6 for master
work).
Comments? Adding also Sandro.
Version 4 of the engine will support versions 3 and 4 of the API, so our
repositories should include version 3.6 of the SDKs (and the CLI) and
also version 4 of the SDKs (there is no version 4 of the CLI). They have
different RPM package names to avoid conflicts.
