[wp-hackers] On Subversion and 2.5.x-alpha not being in Trunk

I think that the branch is already doing what you want. I think the
confusion here is that in a release branch, 'alpha' doesn't necessarily
refer to the stability of the code, as it does in trunk. In trunk, the
'alpha', 'beta', and 'RC' designations have their traditional meanings
that we normally think of in development. But in a branch the WP
tradition has mainly been to stick to 'safe' changes. So you can think
of the 'alpha', 'beta', and 'RC' designations more of a "how soon will
it become a bugfix release" sort of thing.
Here's how I would describe things, as I see it, based on what we've
seen since the original switch from cvs to svn, and the later commitment
to a release schedule:
trunk: Active experimental development for a future 'major' release.
Expect breakage. alpha -> beta -> RC -> Release (copied to tags/X.Y and
branches/X.Y) -> alpha++
tags/X.Y[.Z]: The official release snapshots. Fixed in time, never updated.
branches/X.Y: Active bugfix work, and possibly minor new features occurs
in the newest branch. No API breakage should occur here, unless
absolutely necessary to fix a major bug. At various points, there may be
new point releases created from here, by copying to tags/X.Y.Z
That's my opinion/observation, anyhow. I consider the current branch to
be 'stable', regardless of any alpha/beta designation. One of the
official commit people can feel free to correct me if I'm speaking out
of turn about the safety factor in the latest branch.
Now, as to whether there should be some sort of universal svn 'stable'
pointer that always points to the latest-and-greatest bugfix branch...?
I don't know. I can see how it could be useful for some people, but I
think that upgrading between major releases should be a conscious step.
Automating bugfix updates within a branch is fine. But doing an svn
switch to a new release every few months isn't that big of a version.
And it *can* be scripted, with just a little bit of work.
