Subject Re: [VOTE] Apache Cloudstack 4.10.0.0 RC3
Date Wed, 28 Jun 2017 06:40:31 GMT
Hi,

I personally still like the idea of a new branch being created right around the time we cut
our first RC.

Even if people want to commit changes to the new branch, they should understand that that
code won't be formally released until the pending RC is validated and released.

That being the case, I would think those who choose to commit to the new branch will have
a vested interest in the RC going out, as well.

In any event, in addition to the current automated regression tests that are run, we still
have a lot of tests that are not hooked into the build that are being run ad hoc (managed
storage automated tests are an example). Additionally, we seem to have a lot of manual tests
being run.

Until we can deliver a framework in which we have a very high percentage of the system covered
by automated tests, there is really no way we should consider monthly releases.

I think we are still shooting for releases every four months, which seems fair given our current
system.

If we enact some deadlines like a code freeze going forward, that should help. With only blocker
PRs going into subsequent RCs, we should be able to avoid a lot of unnecessary spin.

I definitely want to point out that I appreciate everyone's time and effort. In particular,
I want to be clear that it is not my intent to be critical of anyone who's been working in
release management. My only goal with this chain of e-mails is to see if we can continue to
improve the process.

Thanks, everyone!
Mike
