New and Noteworthy

EMF Compare/New and Noteworthy/2.1.0

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 made all API from the 1.* stream obsolete. As such, end of life issues only concern the 2.0 as compared with the 2.1 code base.

There are no outstanding issues with the API state of this release. All mehods and classes that face deletion have been marked as deprecated with instructions on how to switch to the new behavior, and will stay in the code base until the next release.

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

911 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 most distinct plug-ins.

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 40% of the java source code.

An analysis of the code base 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

All of the documentation for EMF Compare is available from the wiki. It will be completed and extended with tutorial as this version matures.

Bugzilla

Here is a snapshot taken on May the 15th of all bugs that have changed since release 2.0.0 (Juno). These figures are subject to change until the official release of 2.1.0 as the Team is currently in the process of fixing bugs.

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.* stream.

UI Usability

EMF Compare is conforming to the Eclipse user interface guidelines.
