Split out transaction

[David Blevins <da...@visi.com>]

I monitor a bunch of lists and it looks like the Geronimo transaction  
library is getting pretty popular.  Looks like Ofbiz, ODE, and  
Tuscany are now using it.  That's in addition to ServiceMix,  
ActiveMQ, and of course OpenEJB.

Interesting thing is that their all using it standalone via the  
Jencks.org stuff.

What is stopping us from splitting this out?

I say we just leave the gbeans where they are, rename the module to  
geronimo-transaction-gbeans, then move the rest of the code out, make  
a new pom and mark any deps still required with '<scope>provided'.

Then we cut a release of it that both 1.2beta and 2.0m1 can use

Thoughts?

That not enough? ;-)

Beyond your note, what's motivating us to split it out? ;-)

Certainly makes sense to provide a module which is not dependent on  
GBeans (one day we'll get rid of them altogether...). That seems to  
be the important part of any splitting. This can occur with or  
without moving transactions to be separately releasable...

I certainly wouldn't advocate doing anything like this so close to a  
release or two...

Sure.  We can start creating the separate modules now, but we can  
leave 1.2-beta and 2.0-m1 using their own copies.

Right.  I could take or leave the 'modules' prefix, but it's kind of  
nice.

We can move out now and mark them 2.0-SNAPSHOT.  After 2.0-m1 and 1.2- 
beta1 we can work on getting those codelines to use the independently  
versioned copies and when that works, we release them as 2.0.

The activemq one maybe as I think that one really does only have  
gbeans in it, but the rest have a lot more integration code.  We can  
use any suffix we like really, we just need an artifactId different  
than geronimo-transaction.   In fact we maybe just want to throw the  
leftover gbeans into another module, like geronimo-core.  But we can  
decide that later.

I'm ok for splitting it out.  I'm not sure today is the best timing.   
My experience is the simple things like this as your releasing  
software is the thing that goes belly up and causes great pain.   
We'll have to peel it out, test it, vote on it, etc.

I'd prefer to do this after we get 1.2-beta and 2.0-m1 out the door.

Are you proposing:

geronimo/server/[trunk | branches/1.2] /modules/geronimo-transaction- 
gbeans for the server and branches and

geronimo/modules/geronimo-transaction/trunk/
                                      /tags/
                                      /branches/

for the externalized transaction and connector modules?

So for after 2.0-m1 and 1.2-beta1 we would move it out and version it  
as 2.0-SNAPSHOT and release as -2.0.

This kind of implies that the other modules like tomcat, jetty,  
activemq, etc should be renamed with -gbean suffixes to be consistent.
