Interesting. On the first impression that sounds like a good abstraction

possible and maybe even useful. ;)

 It would be great if that were true.  

That's been my understanding all the time. I think we currently don't do
it because it might be non-obvious to the individual developers at the
time of check-in and due to underused tools.

We may not require that a single developer run all test suites in all
combinations we desire to be compatible, but with the ongoing effort to
improve the nightly/automated builds we should get into better shape there.

The one issue with delayed testing is that we would have to impose a
rule which requires cool down time after a checkin before making a
release. That's probably not a terrible thing anyway.

 I suppose everybody here agrees that any change to a package which is part

 It would be great if that were true.  If so, then the recent arguments
 have been a terrible misunderstanding.

 I think that most of the misunderstanding lies in the nature of
 ownership of the packages in the ZTK:  some would like everyone to
 care equally about all the packages (including those now factored into
 the zopeapp.cfg set), while others want to give most of their attention
 to some smaller set of packages which they use every day.

Something that appeared to me while reading that: the specific set that
a single developer cares for varies over time.

Independent of the specific set I care for at any point in time, I still
am interested in a healthy larger set because I might need that again
tomorrow or next week.

  We already
 have some policies in place which recognize that the bicycle seat
 toolkit packages need special handling, becaues they are used outside
 the Zope ecosystem (one rule is that we attempt to keep Python 2.4
 compatibiltiy for those packages).

 I certainly don't think anybody here would argue against having the big
 'compattest' tests get run:  even the splitters and whittlers (I
 might be called one of those) are willing to help fix things when a
 change to one package breaks the others.  If we could get automated
 testing of the various compatibility sets established, with automated
 reporting of failures, I think we would see a huge improvement in the
 signal here:  instead of arguing hypotheticals, we would be focused on
 fixing real breakages.
 
 +1
 
 Hopefully the discussions about buildbots will bear fruit.

Working on that. :)

 It would be easier to
 find leading developers for subgroups of packages (eg. bicycle repair kit,
 rm generation, ...) willing to raise the quality of a specific subset of
 packages instead of finding a release manager willing to oversee  60
 packages, which he does not really use (because I don't think we have a
 single developer using *all* of the packages in the ZTK).

 These specific leading developers could report and synchronize with a ZTK
 release manager, though.

 There's nothing preventing people from doing this AFAICT.  If someone
 is interested in pursuing a change to a package or collection of
 packages, they can do so with or without some organizational
 structure.  Problems would arise only if they proposed a backward
 incompatible change, which isn't to say that backward-incompatible
 changes are impossible.

 We still mostly treat them as off-limits, even the three years after we
 started the effort to break the monolith apart.  That change should have
 made it technically feasible to do backward-incompatible changes, but we
 haven't yet worked out how to make that happen.
 
 I wonder how many situations there are where backward incompatible
 changes are needed to unblock other work.  I don't suppose we have a
 list of these do we?
 
 One thing that makes problems like this really hard is that email is such
 a terrible tool for much of the needed communication.  It would be nice
 if we could do something more sprinty.  I don't want to help if it involves
 drawn out email discussions, but, FWIW, I'd be willing to allocate some
 concentrated blocks of time for high-bandwidth discussion and work.

Here's a save the date: gocept is organising a summit/sprint close to
this year's DZUG conference which will also have sprinting time and
space all over. So that's definitely high-bandwidth. :)

The summit itself will be more oriented to getting the Zope developer
group organies so we can have less of the meta discussions on the
mailing list (that would probably be the part Jim is uninterested in
;)). I'd like to keep that focused on a single day though and use the
rest of the sprinting time for getting stuff done.

So, anyway, here's the dates:

13. September 2010: zope-dev summit in Halle (Saale), Germany
14. September 2010: sprint in Halle (Saale)
15.-17. September 2010: DZUG conference in Dresden, Geramny
18.-19. September 2010: post-conference sprinting days in Dresden

I'd love to see as many of you zope-dev guys here in our offices. :)

I would think that requiring the buildbots to clear before tagging a new
release of the ztk.cfg file is a good cool down, but we can't require
that people not release the included packages:  the ZTK isn't really
testable without having them released (a chicken-and-egg problem).

I would say that updating ztk.cfg to new major versions of
sub-packages (ones with new features, or potential backward
compatibility issues) requires a great deal more care than updating it
to use a new bugfix only release of a package already in the ZTK.
Adding or removing packages from the ZTK should probably also be a
branch only item, with discussion required here before merging.

May be we will end up with one cfg file for each package :)

I don't think we need to split the cfg files: IMHO what we are looking for
(or should be looking for) is not a technical solution, but something to
solve a management issue.

Having people responsible for a subset of packages does not involve any
change in our technical infrastructure, maybe just a website where to store
the documentation.

Anyway, this is my idea of fragmentation of the ZTK into self-contained
reusable groups of packages, you can like it or not like, it is just an
idea. :)

 Maybe I'm missing something, but zope.event is so minimal I can't see
 that making optional is worth the effort.

Actually, I misunderstood your question. Personally, I also don't think
it's worth the effort. But it's come up a few times already, so is
obviously something some group of people want.

The effort, also, is actually quite small as can be seen on the branch.
Perhaps it's even an effort saver if it prevents the topic coming up
again and again ;)

Good, because while reading you're response I was so confused I worried
that I had recently had a stroke and not realized it yet.

Hopefully the discussions about buildbots will bear fruit.

 It would be easier to

 rm generation, ...) willing to raise the quality of a specific subset of

 haven't yet worked out how to make that happen.

I wonder how many situations there are where backward incompatible
changes are needed to unblock other work.  I don't suppose we have a
list of these do we?

One thing that makes problems like this really hard is that email is such
a terrible tool for much of the needed communication.  It would be nice
if we could do something more sprinty.  I don't want to help if it involves
drawn out email discussions, but, FWIW, I'd be willing to allocate some
concentrated blocks of time for high-bandwidth discussion and work.

Fortunately there are all sorts of free/cheap ways for high bandwidth
communication.  Maybe a free conference call + screen sharing.
If there was an agenda -- I would be more than willing to schedule,
ensure technology is working,  and coordinate people being there.

Some people in the plone community have been doing weekly sprints.
They just completed their 27th weekly sprint.  They spend 6 hours or
so on a set of bugs in the issue tracker.  They do it over #irc.  By
this is still lowbandwidth communications.  Nothing better than
voice + supporting visuals to increase effectiveness.

Again if someone wants to setup agenda I can help w/ logistics and
ensure voice/screen sharing will work for, say, 20-40 people.

Unfortunately I know very little about ZTK and the dependency issues.
I would not be good person to setup an agenda.

 Why wouldn't that be worked out here?  Is it because you just want the
 mechanics of such a project done elsewhere without having to see it
 talked about on this maillist?  Or is it because you disagree that it

 The main issue is related to the different use cases we have for the ZTK:
 some people use (or want to use) the ZTK as a monolithic set of packages
 that can be considered somehow the upgrade path from zope3 with the
 exclusion of zope.app.* (if possible).

 Others (like me and you, Chris) see the ZTK as a set of core packages
 (mainly the bicycle repair kit, which is not the only self-contained subset
 of useful packages though) plus a huge load of dependencies we are bringing
 forward from the old zope3 releases.
 
 Others, like me and Martijn and probably many many others, see the ZTK
 as a set of packages that can be used in various subsets and
 combination.  We want as few dependencies as possible.  We also want a
 configuration of versions that are known to work together because they
 are tested together.  We want stability and we want processes that
 will help us move forward.  

A thought that came up when reading this paragraph: another option
restructuring/grouping to reduce the amount of packages may be to join
smaller packages with weird boundaries into larger ones again. (Not that
I suggest this to be an ultimate option, nor do I know from the top of
my head any candidates for this, but we can keep that on the list of
options we have.)
