Yes, that's what I managed to do : remaned master to a new branch then
checkout upstream/master in local master.
Thanks.

Nicolas,
I think you could just make another branch, or rename the master
branch to something else. Then, you could set up a new master and let
it track the original master?

I'dl like to work on this superbundle using the last version of
neo4j-community. The problem is that i've already forked this repo for my
previous work and now I can't fork it anymore. Also, i've made my
modifications on the master branch.
Do you know a way of getting the last version of the source code without
loosing my previous work ? I was thinking of checking out back to the time
I've forked, then create a branch, then pull changes from the original repo.

Thx.

yes, after looking into the details involved, I think an official
superbundle with the core Neo4j components bundled and exported woudl
be the best way forward. Also, it would expose less granular bundles
into an OSGi environment.

Other IndexProviders etc could be then inserted as fragments into that
bundle.

It would be absolutely fantastic if you could work on that, maybe
using the neo4j-osgi-examples as the demo project? We could then have
a packaging project there or in a neo4j-osgi component that does the
actual production of the superbundle.

WDYT?

Re: [Neo4j] How to embed neo4j to OSGI env without spring?

2011-06-13 Thread Peter Neubauer

Nicolas,
thanks for looking into this! If you only move the LuceneDataSource
into an exported package, for instance org.neo4j.index.lucene, and
export it, would that be sufficient to get the registration done?

I don't want to force OSGi upon all Index provider bundles (yet) and
keep the impact of making this work at a minimum.

Cheers,

 First of all, I got a Framework exception when running the test case out of

 This shows the lucene-index bundle has a unresolved imported package. That 
 strange because lucene-core is deployed wrapped into a bundle just before. 
 There may be a problem with the wrapping process... So, i changed the test 
 case to use org.apache.servicemix.bundles.lucene:3.0.3_1, which is a bundled 
 version of lucene 3.0.3 that i've been using during my forking tests. Using 
 this bundle version and my forked bundles, I get the execution trace shown 
 below. The test case still fails, but somewhere else. Let me explain:
 To manage services loaded using JDK service feature from other bundles, my 
 forked version automatically registers declared JDK services as OSGi 
 services. This is done is the OSGiExtensionLoader.registerBundleServices 
 method 
 (https://github.com/njouanin/community/blob/master/kernel/src/main/java/org/neo4j/kernel/impl/osgi/OSGiExtensionLoader.java).
 So, using my forked version, the LuceneIndexProvider is being exposed as OSGi 
 service, so it is visible to OSGi loader and 
 org.neo4j.kernel.IndexManagerImpl.getIndexProvider shouldn't throw 
 IllegalArgumentException anymore.
 BUT, as shown below, i know have a exception during datasource 
 initialisation. The LuceneDataSource class is not visible to the kernel 
 bundle, where service registration occurs. So I see two possible solution for 
 this :
  - change lucene-index bundle to export-package org.neo4j.index.impl.lucene 
 (bad solution)
  - add a bundle activator in lucene-index bundle to register 
 LuceneIndexProvider service on bundle startup, but I don't know its 
 dependencies.

 Let me know if my analysis is not clear for you ...
 PS : changes made to the test case have been comited to

Just by modifying the test case to register an Index the test now succed :
serviceRegistration = context.registerService( Index.class.getName(), 
db.index().forNodes( nodes ), new Properties() );

(see result below.

So, after all, that make a lot of modifications for OSGi support ... I guess 
the easiest solution would be to create a super-bundle which would 
encapsulates all the actual bundles in only one. This would fix export/import 
package problem, and there could be a specific activator for this bundle to 
register services and OSGi stuff. Let me know if this solution would be 
acceptable, so may be I could work on this.

forked version automatically registers declared JDK services as OSGi services. 
This is done is the OSGiExtensionLoader.registerBundleServices method 
(https://github.com/njouanin/community/blob/master/kernel/src/main/java/org/neo4j/kernel/impl/osgi/OSGiExtensionLoader.java).
So, using my forked version, the LuceneIndexProvider is being exposed as OSGi 
service, so it is visible to OSGi loader and 
org.neo4j.kernel.IndexManagerImpl.getIndexProvider shouldn't throw 
IllegalArgumentException anymore.
BUT, as shown below, i know have a exception during datasource initialisation. 
The LuceneDataSource class is not visible to the kernel bundle, where service 
registration occurs. So I see two possible solution for this : 
 - change lucene-index bundle to export-package org.neo4j.index.impl.lucene 
(bad solution)
 - add a bundle activator in lucene-index bundle to register 
LuceneIndexProvider service on bundle startup, but I don't know its 
dependencies.

Let me know if my analysis is not clear for you ...
PS : changes made to the test case have been comited to

Re: [Neo4j] How to embed neo4j to OSGI env without spring?

2011-06-10 Thread Nicolas Jouanin

Hi,
I'll try this during the weekend if you agree and I'll let you know.


2011/6/9 Peter Neubauer peter.neuba...@neotechnology.com

 Nicolas,
 I have now a failing testcase (albeit using snapshot versions of PAX
 stuff, trying to relax that ASAP) at
 https://github.com/neo4j/neo4j-osgi-examples that exposes the
 IndexProvider not being found in OSGi environments.

 Is your fork of Neo4j Community fixing this issue? In that case, it
 would be great to verify it against the testcase and merge it in!

 Cheers,

Yeah,
that would be great Nicolas! The only thing is that you will need to
build Pax Tinybundles,

Now, with the springsource JTA bundle, the Neo4j Kernel bundle is at least

Guys,
I have tracked down the issues now to the actual thing.
https://github.com/neo4j/neo4j-osgi-examples/blob/master/src/test/java/org/neo4j/examples/osgi/OSGiTest.javanow
wraps lucene, and loads the Activator that tries to get and index, see
https://github.com/neo4j/neo4j-osgi-examples/blob/master/src/test/java/org/neo4j/examples/osgi/Neo4jActivator.java.

I now get

which is exactly the kind of thing we are expecting.

However, it seems the the ServiceLoader approach is not really compatible
with OSGi, see
http://jbossosgi.blogspot.com/2010/01/suns-serviceloader-and-how-it-relates.htmlfor
details. Eelco, did you solve this problem in some nice way so I can
adjust the tests?

2011-06-08 Thread Eelco Hillenius

 However, it seems the the ServiceLoader approach is not really compatible

 adjust the tests?

I'm afraid not. I dropped in the newer version of Lucene, and that
fixed the problem for me, but I'm not doing anything in particular
with OSGi.

If it matters, I'm using Guice for dependency injection, and using
Blueprint to wrap around Neo4J:

import com.google.inject.AbstractModule;
import com.teachscape.commons.settings.Settings;
import com.teachscape.commons.util.Files;
import com.tinkerpop.blueprints.pgm.Graph;
import com.tinkerpop.blueprints.pgm.TransactionalGraph;
import com.tinkerpop.blueprints.pgm.impls.neo4j.Neo4jGraph;
import java.io.File;

public class Neo4JModule extends AbstractModule {

private final Settings settings;

public Neo4JModule(Settings settings) {
this.settings = settings;
}

@Override
protected void configure() {
String graphdir = settings.getSetting(neo4jdb.dir);
File f = new File(graphdir);
if (!f.isDirectory()) {
f.mkdirs();
}

boolean startClean =
settings.getBooleanSetting(graphdb.startClean, true);
if (startClean) {
Files.delete(f); // Neo4jGraph will mark as 'fresh' when
it detects dir doesn't exist
if (f.exists()) {
throw new IllegalArgumentException(
String.format(graphdb.startClean=true, but
can't delete directory %s, f.getAbsolutePath()));
}
}
Neo4jGraph graph = new Neo4jGraph(graphdir);
graph.setTransactionMode(TransactionalGraph.Mode.MANUAL);
bind(Graph.class).toInstance(graph);
bind(Neo4jGraph.class).toInstance(graph);
bind(GraphShutdownHookInit.class).asEagerSingleton();
}
}

Blueprints 0.7, Neo4J 1.4-SNAPSHOT, Lucene 3.2.0.

In my test code, IndexVertex index = ((IndexableGraph)
graph).getIndex(Index.VERTICES, Vertex.class); then works, whereas at
first it didn't because of problem with the older Lucene.

Finally, I found these in JDK_HOME\lib\tools.jar, this is not a part of
JRE but a part of JDK, which means neo4j can't run under OSGI with JRE only

 Does this means neo4j can only run with sun JRE?
