We are doing most of the repository related tests either with hsqldb
that makes it easy to throw away the whole db or with Hibernate that has
an option to recreate the whole db.
That said, the resource management capabilities of CDO are still very
limited. In fact they are currently limited to the functionality that
EMF requires: create new resources and load well-known resources. If you
file an enhancement request for the ability to delete resources you can
track the progress.

You're right, a CDOSessionConfiguration can only create a single
CDOSession instance. Subsequent calls to openSession() will return the
same instance. You need to create a new configuration to open a new session.
Btw. the way to open session will change fundamentally at the very
beginning of the 2.0.0 stream due to https://bugs.eclipse.org/235042 .
And yes, this is an issue of insufficient documentation ;-( Now, that
Simon is working on many of the new features, I hope that I'll have the
necessary time to complete the docs soon.

Eike,
In 2.4 we added support for delete to Resource and URIConverter...

Good to know, but too late for CDO 1.0 ;-(
Maybe I can add deletion support in 1.0.1 via a static helper.
Btw. resource deletion was a feature of CDO pre 0.8.
IIrc. it was not a trivial story because of possible xrefs into the
resource to be deleted.
But with a Bugzilla, André, we can see how to get it again ;-)

Eike,
You're not supposed to change APIs in maintenance stream. I'd leave
this for CDO 1.1. There's nothing stopping you from having additional
releases (assume you do the proper reviews and all). An API addition
does imply you've created a 1.1 not a 1.0.1...

Is it considered an API change if I add a new final utility class with a
static method to delete resources?

Yes its a new class :-) so you have more API.
The assumption in maintence is that I can develop against your 1.0.1
release compile, release and to anybody which 1.0.x of your bundle
installed.
Now that you have matured to a 1.0 release I'd also advice you to take a
look at (if you have not already):
- http://wiki.eclipse.org/Evolving_Java-based_APIs
- http://wiki.eclipse.org/Evolving_Java-based_APIs_2
Do you use the API Tooling to ensure not to break compatility it would
immediately warn you about such mistakes there are so many cases you
miss believe my I know it from JFace?

Hi Tom,
Yes, after initial struggling with the API Tooling I just able today to
set it up for the new HEAD workspace ;-)
Did you know that API usage checking is not performed if no baseline is set?

well i assumed it what should it check against if there's no base-line
:-). Maybe the warning if you don't have a base-line for the project
could be more informative.

no, I mean the API *usage*, which should be baseline agnositic Imho.
If I declare an interface @noimplement and I implement it nevertheless,
it should show a problem, with baseline or without.

A that one, now I understand. You must enable this in PDE! Does that not
work for you?

Hi Tom,
As I said, this seems to be working only with an API baseline set.
I found this piece of code near the beginning of
BaseApiAnalyzer.analyzeComponent():
| *if*(baseline == *null*) {
//check default baseline
checkDefaultBaselineSet();
updateMonitor(localMonitor, 6);
*return*;
}|
Cheers
