In the Linux world, these purposes are served by separate indexes
(e.g. Debian security releases are in their own index). There's no
problem with what you're saying, it's just not a source for
repeatable
installations, which is something that's required for many builds.
Yes, I agree. I accommodated those needs by having versioned
links.html,
versions.cfg, controlled-packages.cfg, and now minimal/ files and
directories. Those will *never* change once released. (Of course
there will
be versions like "3.4.1dev" that change until "3.4.1" is released,
simply so
that I do not have to version every single little change to the KGS
while
testing. But maybe that is even desirable at some point. We will see.)
Sorry, I don't think I understand the last sentence there but I get
the sense from the rest of your message that the minimal index will
not change once released, and new versions of it will be made for each
"release" (however those are defined in a post-big-release world) and
that will be beneficial for lots of people.
Right. Note that versions-*.cfg and links-*cfg are frozen. I am
probably going
to freeze minimal/ as have minimal-*/ too.
Will they will change for bugfixes?
Nope. That's the reason they are frozen. They are like tags in SVN.
OK, that's good to hear.
I have tried buildout, of course. Massaging the index to meet some
set of expectations developers have of the client they use to install
the software is fine, you did a lot of work to do this, which is
appreciated, and it's your index. But I suggest that we don't
discount the *really KGS* requirement, which is *absolutely
repeatable
builds* (today, tomorrow, two years from now), and we let people know
that the KGS is not that.
Why? I have listened to the community very early on, reacting to the
need
having certain frozen output. A few weeks back I sent a mail to the
zope-dev
_[1] list outlining how I think the index can be used in buildout.
Since
then, functionality has only expanded and other combinations are
possible
now.

So if you go to http://download.zope.org/zope3.4/intro.html into the
sub-section "Version 3.4.0b2" you see a bunch of links. With the
exception of
the "Index" link, all other links point to versioned file and
directories,
which will not change. Also, any of the versioned files and
directories do
not contain references to packages that are not controlled by the KGS.
Great. I'm happy to be wrong. A mention on the intro page about how
this versioning scheme is meant to work going forward would be nice.
Nice job,
