So lets do that.
Jeremy was proposing distinguishing between "stable" - where the
focus is getting to the next release - and "unstable" - where things
unrelated to linear progress to a release are done.
First - do we agree this is a good thing?
Second - if we do agree, besides the suggestion of separate roots
("stable", "unstable", "downright_wacky" (nee "sandbox")), what other
approaches are there?
Said another way, the technical discussion of the svn tree will
never get anywhere without addressing this core issue first.
I think that Jeremy's point is one part of the discussion. The
other is how do we break up Geronimo so that people can mix and

lets solve this one first. The other follows after that, IMO.

Right. IIUC, you're saying it's not an all or nothing type of strategy
like we have right now. We need a strategy (and a well documented one)
for addressing the new strategy (when we decide what that is).

Could have been? It still can be. See the svn move command. I've used
it to restructure SVN repos and it works great.

Obviously this would have to be an SVN only exercise, but if you can allow a user/developer to check out X and hide that X is made up of 50 different 'externals', but also allow them to check out just 1 of those 50 modules without having to dig through an entire structure... ? Not thinking you were on track to restructure quite that much, so I'll go back to 'observing'. :-) No, you're right to bring this up. This would be a good way to handle a module structure like Alan was proposing where the modules themselves were at the top level and we had a "J2EE assembly" module that just pulled the others together. AIUI though you can't commit across externals which would mean any work that spanned modules would need to be committed from each one which would be a little awkward. I would hope that the number of such changes will decrease so this will become only an occasional problem. One area where we will be doing work in multiple modules are the runtime/builder pairs - perhaps we can do a hybrid where e.g. jetty-runtime and jetty-builder become a pair of sub-modules under a jetty module. -- Jeremy

Are you now talking about what should be distributed to users as
opposed to the dir structure of the SVN repo? Or are you talking about
the two as one in the same (i.e. certain subsets of the project should
be reflected in the SVN repo dir structure, not hidden in the build
scripts)?

Re: Module restructure
Stefan This is exactly what we have been aiming for :-) To a large extent you can already do this today. You can mix-and-match the different modules simply by providing a custom configuration plan. As a concrete example, this is what we did at Gluecode to build the JOE SE product which aimed at filling your : Servlet + JSP + JMS + services such as deployment, transactions and database access. Geronimo is not a J2EE monolith - it is a collection of system services and a kernel to bind them together. What we certify is a J2EE monolith because it has to pass *ALL* the CTS tests but that is just one assembled form. -- Jeremy Stefan Arentz wrote: On May 27, 2005, at 6:07 PM, Jeremy Boynes wrote: Stefan brings up the question of whether we want to release sub- modules of Geronimo separately. I think this is a good idea and would propose the following restructure of the tree to move in this direction. Let me just explain my motivation a bit, maybe that will also help for the plan. In my original email I said something about not needing all the J2EE stuff. I exaggerated a bit of course, but most of the applications that I have been writing in the last couple of years are done mostly with a subset of the whole J2EE umbrella. Some apps were just some network service wrapped in (JMX) beans, a service exposed with Spring (Burlap, XML-RPC) other apps were simply a web app backed by a shared Spring context. I've never needed all the stuff in J2EE. So far I've always done this on JBoss. Their MBean stuff works ok, but I wish it was easier to 'downsize' jboss to just a container with the stuff I need. That never really seemed to be their goal however. The complexity of their configuration files shows that. So, what I would really like to see wrt Geronimo is an absolute minimal server with add-on packages for things like a web container, jms provider, etc. You want to host a web app? Throw in the Tomcat or Jetty personality. Need JMS too, add ActiveMQ. Persistence? Simply add a hibernate deployer. Mix and match so that it does what your app needs. This is where Geronimo could shine and even take away a large chunk of Tomcat; most people just want to deploy their web app and optionally add some more services without having to understand a full J2EE stack. Geronimo can fill that void extremely well I think. (Simple Web Container .. .. J2EE Monolith) Ok so just complaining doesn't work well for this project, so what I really would like to do is start figuring out how I can give Geronimo 'personalities' for popular combinations of technology. Like, - Geronimo Kernel + Tomcat + JSTL2.0 + Spring + Hibernate - Geronimo Kernel + Web Services - Geronimo Kernel + JMX Enabled custom network service and then do some writing about it on the wiki. Make recipes for people, or even complete packages that are downloadable. I really think this is how Geronimo can also get acceptance with a much larger crowd. S.

I would have thought that would be an assembly that used 90% stable module versions and 10% unstable ones. Where would the hassle be? I also don't see the advantage of this plan over simply creating a branch whenever someone wants to do some disruptive experimentation, and merging the results back in when appropriate. This worked fine for me for the work I did rewriting the jetty deployer. If I understand the svn docs this is more in line with "standard svn practice". The big problem is the merge back. If the main branch is continually evolving then that becomes very painful. The intention here was to have an unstable tree that is continually and rapidly evolving and a stable tree where you can easily merge to because it isn't. The other challenge is to support collaborative development of new features where more than one person can be working on it. That means making it easy to checkout and build the unstable tree. There is nothing precluding what you are saying, either within the unstable tree or in the sandbox. -- Jeremy

I think that this discussion thread now has two distinctly different topics:
a) Geronimo SVN repo restructuring
b) Geronimo modules packaging for user consumption
Can we please split this discussion and keep each one on topic?

Re: Module restructure
I'm worried that it would be a giant hassle to try to assemble a geronimo that is 90% stable and 10% unstable. I also don't see the advantage of this plan over simply creating a branch whenever someone wants to do some disruptive experimentation, and merging the results back in when appropriate. This worked fine for me for the work I did rewriting the jetty deployer. If I understand the svn docs this is more in line with "standard svn practice". thanks david jencks On May 27, 2005, at 11:25 AM, Jeremy Boynes wrote: Aaron Mulder wrote: On Fri, 27 May 2005, Geir Magnusson Jr. wrote: so we have /trunk and /branches/stable and /branches/unstable, the former for release work, and the latter for really nutty stuff that people want to work on, and head is where mainline development continues?

I'm not a committer, nor have I been more than an observer to what
Geronimo is doing and where it's going - primarily because everything
I've seen has placed it in the JBoss realm. I've used JBoss for quite a
while and am always amazed at the functionality it has ingrained in it
for which I just have no use. Most of my time spent upgrading is in
finding out how to turn things off that have changed.
This message caught my attention. For the first time, I've seen that I'm
not the only person who things this might be a good idea. I don't want
the world in a server - I just want to be able to add the pieces if/when
I need them to an existing server. This is something JBoss bypasses
entirely... you want to be able to add the pieces? voila - they're added
- - enjoy - whether you wanted them all 'built-in' or not.
I do think this will lead to greater adoption by new users (as well as
those others who want what I do - "the minimal server to do the job,
with expansion capabilities"), as well as greater 'user questions' ("Why
do I get this error?" "Because you don't have the Web Services package
installed/configured"). Questions can be documented all over the place
and users will still come to the mailing list and ask. That, however,
IMHO, is much better than those users already having a "monolith" and
sticking with it rather than move to a Geronimo "monolith" (monolith
used here not in a single application of monolithic proportions, but the
server with mandated functionality that, even when disabled, is still
taking up space). And I'm a firm believer that "it's on the Wiki" isn't
a substitute for good documentation included in the product - it's an
added method of documentation.
As for the pre-packaged versions - I think this would, indeed, be a boon
to Geronimo - - - as long as the individual 'services' were packaged for
some sort of 'drop-in deployment' into an existing Geronimo server as well.
My thoughts...
Brian
