Re: Thoughts on the Nova PTL


Well said, Vish. A few comments inline below. The parts I snipped out
were the ones I entirely agree with or had no comments on...

Much agreed on authn/authz, as I think that is an area that we can
achieve agreement on.

But for other things like configuration/CLI options, there is quite a
bit of disagreement between the projects. Discussions in the past
about stuff like this has devolved into either non-productive
flame-war-like threads or non-productive compromises that nobody is
happy with and so nobody uses them.

The danger of having a PTL focusing on integration efforts with
openstack-common is having the PTL's attention be sucked down the
black hole of endless discussions about code style and what "the best
practice" is for doing X. Not saying it's an unworthy goal to achieve
some commonality, but the PTL shouldn't, IMO, be the driver here.
Better to have some working group devoted to finding common ground.
The PTL could end up being on that working group, but could just as
likely not be on it.

Again, this will meet with disagreement between the teams working on
the various projects. Or are you specifically referring to the Nova
code consistency here? Because I'm pretty sure the Swift devs aren't
going to be interested in having Swift's code look and feel like
Nova's codebase, and asking for cross-project code style consistency
is going to be one of those black hole conversations, with various
groups insisting their way is the "right" way, etc. And here, I don't
just mean stuff in pep8, but the focus on object-orientation, the use
of various libraries, the use of various abstraction techniques, etc,

To repeat, all the snipped parts of your message (most of it), I
completely agree with and fully support you.
