Hi (Eike),

In my effort to make Edapt support CDO model evolution, I need so help
understanding CDO and EPackages.

In the test case I work on I have this scenario:

Repo1 (source)

- Native packages
- Many resources conforming to native packages.

Repo2 (target)
- Empty


When I read a resource from Repo1 and I get an exception when calling
EcoreUtil.resolveAll(resource)

This is a Junit testcase, so the platform is not running and the native
EPackages are not registered by the platform. (The generated EMF code
for these packages is not present/available in the test case).

Now I gather that the EPackage should be registered, so I make sure the
EPackages are registered by the CDOViewProvider when unknown in the code
below. (Note: The EPackages are created from the .ecore file and added
to the resource set). However the CDO packageRegistry will report the
nsURI is already a known key, so adding is not allowed.


Thank You!
Christophe
----------


Exception:


Registry packageRegistry = resourceSet.getPackageRegistry();
if (!packageRegistry.isEmpty()) {
CDOPackageRegistry cdoPackageRegistry = session
..getPackageRegistry();
for (String nsURI : packageRegistry.keySet()) {
EPackage packageToAdd = packageRegistry.getEPackage(nsURI);
if(!cdoPackageRegistry.containsKey(nsURI)){
cdoPackageRegistry.putEPackage(packageToAdd);
}
}
}


So now I am slightly confused, why will I get the exception below, while
the CDO Package registry reports it knows the nsURI?

Is it possible to work with resources with native packages
in a CDO repo, while the generated EPackage code is not available?

what does type=UNKNOWN mean?


Also, I tried this option:

session.options().setGeneratedPackageEmulationEnabled(true);

With this the Exception is gone, but later on I get a commit exception,
NPE on a missing EPackage. (I will report this Exception if needed later
on).

Hi Christophe,

If the original type of a model is NATIVE then either the current type must also be NATIVE or you must set
session.options().setGeneratedPackageEmulationEnabled(true).

The rest of your post was a little vague so I'm unsure what else to say.

Cheers

Sorry about being vague,

How do I interpret 'original' and 'current'? Is this in relation to the
Session which 'was' and 'is' used?

My question boils down to this, I want to work with a repo which has
NATIVE packages, but.... I don't have the NATIVE package. (assume, I
don't have the .genmodel which was migrated to CDO and used to generated
native CDO code). So I can't do MYPACKAGE.eInstance to retrieve it, add
it to GlobalRepo or put in the CDO package registry. So which options do
I have? (besides setGeneratedPackageEmulationEnabled(true))

Sorry, I should have been clearer. The "original type" of a model is the type it had in the client that committed this
model originally (and at the time of that commit). The (current) type of a model is the type that's currently valid in a
client. The type can change when generated packages come and go.

Why besides? I think that setGeneratedPackageEmulationEnabled(true) is the way to go. The general behaviour is the
following:

When a CDOSession is opened the server sends a list of all registered nsURIs, or more exactly a list of CDOPackageInfos,
which are then put as EPackage.Registry.Descriptors into the session's package registry. When their EPackages are needed
they're are resolved. That means that first an attempt is made to "load" them from the global package registry. If that
fails and GeneratedPackageEmulationEnabled==true the XMI of that package is loaded from the server and used to emulate
the originally generated package.

Cheers
/Eike

Ok, when I turn it on it all resolves, so it seems to work.

I get another Exception when commiting the resource to the target repo.
though. I am not sure this exception is related. It seems the ePackage
is not set in a Package unit. I did call:

session.getPackageRegistry().putEPackage(packageToAdd);

....before trying to commit the resource.

From the server trace (further down below) , I see it tries to register
the evolved EPackage as a Dynamic package.. but failing with the
exception.

To summarize:


Edapt <-- Source repo with Native Packages, read Resource A.
|
| (EPackage and model transformation).
|
V
Edapt --> Target repo with Dynamic evolved EPackage write resource A.
(Evolved EPackages are registered on the target repo).

I would try to read the old model with dynamic (also NATIVE!) packages and write to the target repo with the generated
evolved packages. Can you try that?

Hi Eike,

See inline response below.

Cheers Christophe

ps. As discussed earlier, the scenario I am testing is only one of the
two envisaged 'solutions'. Scenario 2 is apply a History on the DBStore
directly. I would like to discuss scenario 2as well. Perhaps not in the
forum...

Ok, this package is the evolved EPackage. It is created by Edapt when
walking the history. The first release of an Edapt history is considered
to be the base EPackage, then following releases modify this EPackage.
It's important to understand, that during these migrations, code is not
generated. (So the Native packages are not available).

I blogged about how this works here:

I can likely load with the NATIVE packages, but writing with NATIVE is
going to be tricky. In the Edapt evolution, code is not generated based
on the new EPackage. BTW this scenario works well:

Regular XMI Resource --> Source repo with Dynamic EPackage, write
Resource A.
|
|
V
Edapt <-- Source repo with Dynamic EPackage, read Resource A.
|
| (EPackage and model transformation).
|
V
Edapt --> Target repo with Dynamic evolved EPackage write resource A.

Yeah, i definitely favour scenario 2 because it's clearly way more performant and scalable. We can discuss it in the dev
list or a bugzilla if you want.

This is just the way Edapt works. Edapt did not envision needing the
generated packages, as they can be constructed from the .ecore. I guess
it would complicate things, considering various Releases of a History,
meaning various code generation cycles for one migration.
