Hi all,
Pretty strong consensus is that the LV2 specs being a bunch of packages
is a nuisance. So, I plan to start releasing them all in one package.
People have asked for this, but I'm not positive it's what they want.
The main odd consequence would be packages checked by configure scripts
(via pkg-config) will not correlate with tarballs. For example, a
program may check for lv2-state-2.4 but no tarball with that name will
actually exist. It will be in lv2-everything-2012-03-21 or whatever.
It would be difficult to correlate which version of lv2-everything
contains a recent enough version of what you need, if something is
failing to configure.
I don't think it's feasible or wise to mash everything in to one package
right down to the pkg-config level, but I'm open to arguments otherwise.
Extensions are independently versioned so changes to them don't affect
the version of others. In all the ways that count, extensions are
completely decentralized and separate (anyone can make one and
distribute it, or not, on their own), but maybe that doesn't mean they
need to be packaged that way?
In short, I am ready and willing to reshape the packaging to make life
easy and to ease adoption as much as possible, but nobody has come up
with exactly what that is. All suggestions welcome, including blatant
"this is all ridiculous crap and you should just <painfully simple
approach here>" kind of thoughts...
Cheers,

Good move.
To avoid any confusion about the packages in each release, you could
just accompany each tarball with a manifest that lists the version
information; I guess that this could be generated automatically from the
version numbers in the corresponding manifest.ttl files. And you could
maybe offer a little download page where this information is readily
available in table form so that users and package maintainers can
quickly find the version(s) that they want/need.

sha-sum the whole thing. the result is the name of the release.

There is a certain elegant simplicity in depending on the state of "LV2"
as of YYYY-MM-DD. I am very attached to the decentralized nature of
LV2, but that doesn't mean the actual packaging has to be a shotgun
blast.
The way reality has worked out, stable extensions need to be curated at
lv2plug.in or they tend to rot and confuse people. Perhaps the
extension mechanism should only really be used during the development
process, and we actively *do* want "LV2" to be a collection of
peer-reviewed specs that work nicely together you can grab in one place
and get on with your work.
In other words, perhaps a decentralized specification is a failed idea,
and we don't actually want to encourage independent
extension /publication/. You're still free to actually design and
implement features with no centralized authority, but if you want it to
actually be implemented by others, it should move in to LV2 proper when
it's ready.
It is with reluctance that I admit this, but that seems to be the
conclusion of the experiment.

Downstream distros wanting to use a git snapshot can still do so by way
of there package release number. ie 2.x-0.1.git1A2B3CF

It seems important that a version bump in, say, the state extension,

developers that don't use state. However, perhaps this argument is
invalid since LV2 specifications never break (their URI must change if
they do, there is no major version).
That's a pretty dramatic change, but it is simpler... a lot simpler...

I like the idea of an overall version number, so, LV2 V2.1 is released
which contains foo v0.7, ba v1.1, thing v0.4.
Over time foo is updated to v0.8, LV2 V2.2 gets released.
Any client/host using LV2 can then claim a version compatibility, ie
V2.1, but not V2.2.
Seems the most understandable approach to me, in my layman's terms.

Done. With respect to pkg-config, the "lv2core" package will remain,
for compatibility. Otherwise, there is just an "lv2" package.
Configure scripts can just check whatever version of that.
Generally, APIs should have meaningful version numbers, but I can't come
up with a scheme for this. People seem to not like the date thing,
though, so "lv2" currently has the completely arbitrary version
"0.1.0".
I guess I will just increment whichever digit I arbitrarily feel like
incrementing that day...
Developers currently following the bleeding edge should dump all their
extension specific pkg-config checks and simply check for 'lv2'. The
price of this change is minimal sympathy for stagnant crap: the
benevolent dictator model will indeed keep things more agile and
unified, but only if you keep up.

Found this in my spam folder some days ago:
Loony Vacations 2 - The next generation Holiday experience.
We at Loony Vacations 2 offer a unique holiday formula.
When you become a member of our customer society, you can
book a trip to any of our holiday resorts, and stay there
for as long as you care. And what's more, you only pay once,
and only for the Experiences you want. All our resorts provide
basic accomodation - a dorm with bunk beds. Everything else
you want you specify in the list of Experiences for which you
are prepared to pay. Actually, when you book a trip to any
of our resorts, there is no guarantee that all the Experiences
you want will be available there, and you only know when you
arrive. That should not spoil your holiday, just make the best
of it. We have no control over the resort owners, they offer
what they are best at. Also, some Experiences may be change
over time. For example the 'Italian Wines' Experience was not
very popular, and therefore it was recently replaced by the
'Belgian Beers' one - offering our customers who like wines
an unique opportunity to discover something new. Of course,
you can always build your own resort, with all the Experiences
you like, and we will be happy to add it to our offer. Also,
we don't discriminate against any of our clients. Your fellow
holiday makers may be hooligans that stay drunk all day and
keep you awake at night. That's not really a problem, we try
to be a happy community anyway. We are looking forward to take
care of your next holiday !
Ciao,

If the tarballs are out there, you can't keep the package maintainers

I guess the question isn't so much tarballs, but whether there should be
a build script in each. I guess not, if we're doing the all in one
thing, and encouraging that all the way through to the package manager.
Programs and documentation should be packaged separately though. Since
most build systems that build docs do it all in one go, I assume
packagers are already accustomed to piecing up things that are installed
in one command by the source build system?

Yes. At least that's the way it is on the distros I know. This depends
on the distro's packaging policies, though. In any case, I'd say that's
something you can just leave up to the downstream maintainers.
