-Re: [DISCUSS] Bigtop "singularity" branch/release
Konstantin Boudnik 2013-08-07, 04:39
I might have a deja-vu, but I think we had this chat in the past: about making
odd/even releases with different stability scope (essentially similar to that
of Debian/Ubuntu model).
Anyway, I think it totally makes sense to have stable/stinging model moving
forward and I would be certainly very interested in helping with stable line's
There is a couple of concerns I want to discuss/clarify:
# do we have enough bandwidth (like you've pointed earlier) for that
# would we need a certain level of cross-branches cooperation especially in
the area of deployment and the base framework (aka Bigtop) improvements? Is
Bigtop itself is in a good enough shape where such cross-branches
pollination would be limited and manageable? Or, perhaps, stable releases
won't live for too long and this issue is totally immaterial?
Another way of addressing this multiple personality condition of Bigtop - as
Roman suggests in another email - is to do post-singularity work on a branch
without specific release dates/numbers in mind. Once there's a feeling that
such a post-singularity branch has ripened - we just release it, maybe with the
even/odd theme in mind.
So essentially there two options as I see it:
- official acceptance for odd/even - or similar - release model with
different stability scope
- or going more agile - don't get me wrong, I don't like the word myself -
and do all experimental development on a branch a release it on as needed
The latter in my opinion is a more sustainable approach going forward, because
it helps to bake new features on an experimental branch for a while and, if
needed, get selectively ported onto the current release branch. Which
accidently goes hand in hand with my favorite nvie.com/git-model
I believe the second choice above is essentially what you've proposed below
but expressed with Russian accent ;)
