Equinox Planning - 3.3

Equinox Planning - 3.3

General Planning Notes

Note: This is just a random collection of notes and thoughts and does not reflect the actual committed plan items for the Equinox team.

  • Declarative Services
    • Implementation
    • Tooling
  • Update Manager
    • The update manager code ownership is migrating from Toronto to Ottawa. We need to keep on top of bug reports and current problems to ensure that nothing slips by for 3.2.1.
    • We need to investigate refactoring the JarProcessor code. It was put into the Update bundles at the end of the 3.2 cycle but is more generally useful.
    • JarProcessor - might be some more work here w.r.t. JAR signing and nested JARs
  • Provisioning
    • Prototype
    • Investigate MEG
    • How to deliver Eclipse?
      • Small installer download?
      • Dynamic web content that builds zip?
  • PDE/Build
    • Continue investigation into inter-operability with Maven
    • Incremental building
  • Component Model
    • The programming model.
    • Investigate Spring, DS, etc.
    • We want to get people off the Platform class.
    • Need to have something easy for people to use when they migrate their code.
  • OSGi Framework (refactor/etc)
  • Investigation into Security
    • Login authentication
    • Securing the code base (Java 2 security)
  • Launching
    • Launching the VM in-process
    • Splash Screen
    • fast workspace switching (currently we don't have any lifecycle events for location areas)
  • Preferences
    • API fixes
    • use everywhere - get people to adapt and get off the old JFace and Runtime prefs code
    • should we create more scopes?
    • Work on an RFC for scopes as they seem generally useful. (particularly for searching)
    • use common storage solution (described below)
  • Version Tools
    • We have started working on some version verification tools to help people cope with the new plug-in (and feature) version number story.
    • Super cool goal is to complete these tools and have them integrated into the SDK.
    • Cool goal is to have them available as either part of the Core Tools or PDE Tools.
  • Storage Service
    • Many different components have to serialize and they all roll their own storage solution whether it be using Properties files, ObjectOutputStreams, or another format.
    • We should investigate a common storage service that multiple components can leverage.
  • Service Registry
    • Lazy Tracking
    • Scalability issues for event dispatching and registry impl
  • Refactor Test Suites
    • We used to have one test plug-in for each plug-in in the SDK.
    • Now that we have refactored the runtime we should also refactor the test suites to match the new bundle structure.

Milestone Plans

Eclipse 3.3 M4 - Friday, December 15, 2006

New Lancher Work

API Tooling

The goal of this work is to provide a tool to help check backward compatibility on an API level and trace API and non-API dependencies both upstream and downstream. It is likely that some of the work will be done in cooperation with the PDE UI team. In M4 we work on:

  • Initial work on the engine for collection and comparison of APIs - to be used for backward compatibility checks
  • Initial work on the tool for collection of references to APIs/non-APIs in other projects - allowing developers to trace usage of their code by other plug-ins
  • Find a home in one of the incubators for this work

The Supplement Bundle

Generally speaking, the org.eclipse.supplement bundle is a collection of classes that are required for the registry to run outside of OSGi. It also should contain the classes necessary to run the registry on another framework.

Currently this bundle lives in a separate project in the Eclipse repository so therefore the classes are copied from the org.eclipse.osgi bundle and live in 2 locations. We need to make it easier to maintain the code whether it be by combining the projects into one so there is only one code base, or by some other means.

The goal for 3.3 M4 is to have the supplement bundle work completed. The code should be maintained from a single location be able to run both with and without OSGi present.


Continued contribution of bundles to the Orbit project.

Eclipse 3.3 M5 - Friday, February 9, 2007

API Tooling

The goal is to have something consumable by end users for this milestone. Build details still need to be worked out, but we would like to at least have something that the user can download and build/install/use.


  • Contribute the JMX bundles which are currently part of the Equinox Incubator.
  • Verify that all the Eclipse SDK bundles that are intended to be a part of Orbit, have been contributed


There are some lingering bugs that we will take care of as well as releasing helper code for plug-in developers who are creating their own preference scopes. Deferred to next milestone

Framework Handler

We are currently investigating a common API for handling framework and launcher configuration and startup. This involves creating an API for setting parameters, etc which will work across multiple frameworks. We intend release the initial APIs into the Equinox incubator for comment for the M5 milestone.

Equinox Launcher

The new equinox launcher is now in. The following items need to be addressed for M5

  • Determine impact on build/export 168616
  • Support launching java.exe in the old way, 168775
  • Figure out problems on x86_64, ppc, & aix. 168271 168278 168281
  • Console issues on Windows 167310
  • support reading a VM description file


  • The plugin contains APIs that would be useful in standalone Java applications. We should ensure this

plugin can be used simply by adding it to the classpath of an arbitrary Java application. In particular, see 124968.

  • The debug framework has a notion of background units of work: IRequest. This is currently not based on jobs because some debugger implementations may not want to use the job manager's scheduling and thread pool to execute these tasks. Investigate whether there is an interesting abstraction that can be pulled from the commonality between IRequest and Job.

Eclipse 3.3 M6 - Friday, March 23, 2007 (API Freeze)


  • EclipseCon 2007 is March 5-8, 2007 so a lot of time has been put into talks, tutorials, and demos for the conference.

API Tooling


  • Ensure that all relevant Platform bundles that can be contributed to Orbit, are.
  • Help the Release Engineering team modify the Platform builds to consume as many Orbit bundles as possible.

Eclipse 3.3 M7/RCO - Friday, May 4, 2007 (Feature Complete)


  • Help release Ant wrapper to SDK builds
  • Work through remaining issues with JUnit and wrapper bundle
  • Verify license files in platform contributed bundles
  • More work on the IP Log file


  • A performance dynamic team will be created and we will participate.
