How far is the 4.2 Spec implemented?

Hello,

I am new to the OSGi and Java world. At the moment I am working on a paper in which I want to compare how far Felix, Equinox and Knopflerfish are implementing the new OSGi 4.2 specification.

Sadly, I couldn't find a lot informaton about that on the Felix homepage.

The "Framework" subproject seems to implement the whole Core specification. Is that correct? Or are there parts of the Core specs that are not implemented yet?

To be more precise I mean:

- Security Layer
- Module Layer
- Life Cycle Layer
- Service Layer
- Framework API
- Package Admin Service
- Start Level Service
- Conditional Permission Admin Service
- URL Handlers Service
- Service Hooks

And how about the Compendium Specs? How much of these specs are covered by Felix?
On some of the parts of the Compendium spec (see below) I could find a subproject. For instance the "Log Service" is implemented by the "Log" subproject.

- Remote Services
- Log Service
- Http Service
- Device Access
- Configuration Admin Service
- Metatype Service
- Preferences Service
- User Admin Service
- Wire Admin Service
- Initial Provisioning
- UPnP Device Service
- Declarative Services
- Event Admin Service
- Deployment Admin
- Auto Configuration
- Application Admin
- DMT Admin Service
- Monitor Admin Service
- Foreign Application Access
- Blueprint Container
- Tracker
- XML Parser Service
- Position
- Measurement and State
- Execution Environment

I hope you can help me since I can't find any information about that anywhere.

With best regards
Jens

The core framework passes the R4.2 mandatory CT tests since version 
2.0.0 and passes the complete CT (i.e., including security) since 
version 2.0.4.

We do run the TCK regularly to validate if Felix passes all 4.2 tests:

<shameless-plug>

Two of my colleagues started an open source testing framework that runs a test suite on all leading open source implementations. Check it out. And we could definitely use help extending the test suite itself. :)

For an overview:
http://opensource.luminis.net/wiki/display/OSGITEST/OSGi+testing+framework

For a nice matrix of tests and frameworks:

It has some issues when used together with an Event Admin service. No release yet.

We have an implementation. It's been a while since I used it, but it basically works.

AFAICT the latest release of the framework implements the full 4.2 core
specification. Richard Hall and/or Karl Pauls may know better.

We don't have this implementation. But IIRC Apache CXF has an
implementation which happens to be the OSGi reference implementation.

> - Log Service

Multiple implementations exists. We have a simple one based on Log4J
(based on the one provided by the OPS4J project). The Apache Sling
project has another one.

> - Http Service

We have two implementations. Both implement the R4.2 compendium
specification but not the recently released R4.2 enterprise
specification extensions.

Maybe Apache Aries is working on an implementation of the enterprise
extensions.

> - Device Access

Don't know myself.

Yes and our implementation happens to be the OSGi reference implementation.

> - Metatype Service

Yes.

> - Preferences Service

I think, yes.

We have an implementation, but I don't know about the specification
compliance.

Don't know myself.

I don't think so.

We have an implementation, but I don't know about the specification
compliance.

In addition we have a new Web Console plugin supporting UPNP.

Yes.

Yes, though it is not entirely complete. IIRC it lacks deinstallation
functionality.

AFAICT we have partial support. Maybe Richard Hall knows more about this.
