Subject Re: [PROPOSAL] move away from time-based releases and/or revamp release process
Date Tue, 24 Sep 2013 19:09:36 GMT
I was a bit hesitant to keep pushing this because there doesn't seem to be
a lot of support for it, but - as Marcus pointed out - I was quite alarmed
by the number and criticality of bugs checked in right before we cut our
first RC for 4.2. We simply were not ready.

To me, it felt like something one might do before one gets out a decent
beta release.

I certainly don't claim to have all the answers for this, but I do think we
need to develop some kind of a process whereby very few changes are made
immediately prior (like a month) to the first cut of a RC. We might even
need to discuss such changes as a community before they get checked in
(after a certain point).

As far as master not always being usable, this is a serious problem, as
well.

For example, I've been having trouble getting KVM to work and - in the
meanwhile - my code has fallen out of date with master over the past week
or so. However, I'm always afraid if I update from master while in the
middle of solving one problem that I'll have more problems to deal with
before I can get back to the initial problem (because something didn't work
in master).

Again, I don't claim to have any solution for this problem, but I am happy
to help brainstorm.
