EMF Compare 2.0

Release Review : July 31, 2012
Communication Channel : eclipse.modeling.emf newsgroup
Process Documentation : http://www.eclipse.org/projects/dev_process/development_process.php
Project Plan : http://www.eclipse.org/modeling/emf/compare/project-info/plan-2_0.xml
Release Highlights
EMF Compare 2.0 is a full overhaul of the design, architecture and code of the project. It aims at providing the same functionality as 1.3 did while lifting the limitations that it presented.
The 2.0 release only targets the comparison of models that present IDs of some sort : XMI ID, functional ID... The subsequent 2.1 version will catch up to 1.3 in terms of SYSML-specific differences and graphical comparison.

Quality of APIs
The component lead certifies that the requirements for Eclipse Quality APIs have been met for this release. All non-API code is in "internal" packages.
End of Life Issues
EMF Compare 2.0 being a full overhaul of the project, its API is not compatible with its previous 1.* versions. A migration guide will be provided in order to ease the adoption effort to this new version.
All API that was provided by the 1.* stream has been deprecated with the 1.3 release (see the 1.3 End Of Life Issues) and is no longer available in its previously existing state.
The extension points proposed by the 1.3 release have not been ported yet to the 2.* stream, but should be pressent in the subsequent 2.1 release.
The commiter for the MPatch plugins is now inactive, and this feature is thus no longer supported. There are no plans for the moment to port these plugins to the new core of EMF Compare.

Non-Code Aspects
Continuous Integration
Project is built from the Eclipse hudson instance through Tycho. A nightly is built once a day if the SCM polling sees a change from the last build.
Unit Tests
349 unit tests launched on every build.
Code coverage is about 80% of the core.
Code Quality
Common formatter and compiler configuration used throughout the whole project's plug-ins.
Checkstyle activated on each distinct plug-in.
Eclemma used on a regular basis to ensure and improve code coverage from the unit tests.
Yourkit java Profiler used on a regular basis to improved performances and avoid bottlenecks.
Findbugs launched on a regular basis to avoid detectable bugs.
Javadoc represents about 50% of the java source code.
An analysis of the code base page is available on Ohloh.
APIs
Metamodel definitions and interfaces are considered APIs.
Commitment to provide stand-alone comparison feature (Jar that can be used without Eclipse with minimal to no dependencies towards eclipse core Jars).
Non-API classes are separated from the exposed API through an "internal" namespace.
Non-API packages are exported with an internal visibility so that they remain visible but with a discouraged access warning.
Documentation
Documentation is not up-to-date yet.
Bugzilla
No Bugzilla closed specifically for this release, however, all bugs closed for 1.3.0 had their fix up-ported to 2.0 so that no regression would be observed on the up-ported features and functionalities. See the Bugzilla snapshot for the 1.3 release.
Tool usability
Localization : integrated into Babel
Standards
No standard exists concerning the model comparison, though EMF Compare works nicely with any standard-based metamodel.
Since the 1.2 release a specific support for the UML standard is included in EMF Compare. This is also included in the 2.0 release.
However, the 1.3 release saw the inclusion of a specific support for the SYSML standard comparison. This has not been up-ported to 2.0 yet.
UI Usability
EMF Compare is conforming to the Eclipse user interface guidelines.
Communities
Talks have been given on the following events: Eclipse Con Europe 2011 :
- What every Eclipse Developer should know about EMF
- What the heck are logical models?
- EMFCompare improvements: fulfilling requirements of the Modeling Platform Working Group
Talks have been submitted for the following events: Eclipse Con Europe 2012:
Other medium:
