Project Plan For JDT Core, version Indigo

Introduction

Last revised 16:00 ET April 27, 2011. ((new) marks interesting changes since the previous draft of December 23, 2010.)

Please send comments about this plan to the eclipse-dev@eclipse.org developer mailing list.

This document lays out the feature and API set for the next feature release of the Eclipse SDK after 3.6, designated release 3.7 and code-named Indigo. This release is occurring simultaneously with the 4.1 platform release. The 3.7 release is a mature platform release, while the 4.1 release includes early versions of the next generation platform and represents the long term direction for platform client UI technology. See the 4.1 release plan for further details.

Plans do not materialize out of nowhere, nor are they entirely static. To ensure the planning process is transparent and open to the entire Eclipse community, we (the Eclipse Project PMC) post plans in an embryonic form and revise them throughout the release cycle.

The first part of the plan deals with the important matters of release deliverables, release milestones, target operating environments, and release-to-release compatibility. These are all things that need to be clear for any release, even if no features were to change.

The remainder of the plan consists of plan items for all of the sub-projects under the top level Eclipse Project. Each plan item covers a feature or API that is to be added to the Eclipse Project deliverables, or some aspect of the Eclipse Project that is to be improved. Each plan item has its own entry in the Eclipse bugzilla database, with a title and a concise summary (usually a single paragraph) that explains the work item at a suitably high enough level so that everyone can readily understand what the work item is without having to understand the nitty-gritty detail.

Not all plan items represent the same amount of work; some may be quite large, others, quite small. Some plan items may involve work that is localized to a single component; others may involve coordinated changes to several components; other may pervade the entire SDK. Although some plan items are for work that is more pressing than others, the plan items appear in no particular order.

With the previous release as the starting point, this is the plan for how we will enhance and improve it. Fixing bugs, improving test coverage, documentation, examples, performance tuning, usability, etc. are considered routine ongoing maintenance activities and are not included in this plan unless they would also involve a significant change to the API or feature set, or involve a significant amount of work. The intent of the plan is to account for all interesting feature work.

The current status of each plan item is noted:

  • Committed plan item - A committed plan item is one that we have decided to address for the release.
  • Proposed plan item - A proposed plan item is one that we are considering addressing for the release. Although we are actively investigating it, we are not yet in a position to commit to it, or to say that we won't be able to address it. After due consideration, a proposal will either be committed or deferred.
  • Deferred plan item - A reasonable proposal that will not make it in to this release for some reason is marked as deferred with a brief note as to why it was deferred. Deferred plan items may resurface as committed plan items at a later point.

Release Deliverables

The release deliverables have the same form as previous releases, namely:

  • Source code release for all Eclipse Project deliverables, available as versions tagged "R3_7" in the Eclipse Project CVS repository.
  • Eclipse SDK (runtime binary and SDK for Equinox[*], Platform, JDT, and PDE) (downloadable).
  • Eclipse Platform (runtime binary and SDK for the Equinox[*] and Platform only) (downloadable).
  • Eclipse RCP (runtime and source repositories for the Rich Client Platform) (downloadable).
  • Eclipse JDT (runtime and source repositories for the Java Development Tools) (downloadable).
  • Eclipse PDE (runtime and source repositories for the Plug-in Development Environment) (downloadable).
  • Eclipse SDK Examples (downloadable).
  • SWT distribution (downloadable).

* The Equinox Project is part of the top level RT Project. A significant portion of the Equinox deliverables are consumed and redistributed as part of the Eclipse Project's SDK, Platform, and RCP deliverables.

Individual, milestone level plans for the components that make up the Eclipse Project can be found on the Eclipse Project Indigo Plan page on the Eclipse wiki.

Our target is to complete 3.7 in late June 2011, in alignment with Indigo. All release deliverables will be available for download as soon as the release has been tested and validated in the target operating configurations listed below.

Dates for builds and test passes after M7 are available in the Eclipse Indigo end-game plan.

Table of Contents

Target Environments

In order to remain current, each Eclipse Project release targets reasonably current operating environments.

Most of the Eclipse SDK is "pure" Java code and has no direct dependence on the underlying operating system. The chief dependence is therefore on the Java Platform itself. Portions are targeted to specific classes of operating environments, requiring their source code to only reference facilities available in particular class libraries (e.g. J2ME Foundation 1.1, J2SE 1.4, Java 5, etc).

In general, the 3.7 release of the Eclipse Project is developed on a mix of Java SE 5 and Java SE 6 VMs. As such, the Eclipse SDK as a whole is targeted at all modern, desktop Java VMs. Most functionality is available for Java SE 5 level development everywhere, and extended development capabilities are made available on the VMs that support them.

Appendix 1 contains a table that indicates the class library level required for each bundle.

There are many different implementations of the Java Platform running atop a variety of operating systems. We focus our testing on a handful of popular combinations of operating system and Java Platform; these are our reference platforms. Eclipse undoubtedly runs fine in many operating environments beyond the reference platforms we test. However, since we do not systematically test them we cannot vouch for them. Problems encountered when running Eclipse on a non-reference platform that cannot be recreated on any reference platform will be given lower priority than problems with running Eclipse on a reference platform.

Eclipse 3.7 is tested and validated on the following reference platforms (this list is updated over the course of the release cycle):

Operating System Version Hardware JRE Windowing System
Windows 7 x86 32-bit Oracle Java 6 Update 17
IBM Java 6 SR8
Win32
x86 64-bit
Vista x86 32-bit

IBM AIX 5.3 Power 64-bit IBM Java 6 SR8 GTK
Apple Mac OS X 10.6 Universal 32-bit Apple Java 10.6 Update 2 Cocoa
Universal 64-bit

As stated above, we expect that Eclipse works fine on other current Java VM and OS versions but we cannot flag these as reference platforms without significant community support for testing them.

Internationalization

The Eclipse SDK is designed as the basis for internationalized products. The user interface elements provided by the Eclipse SDK components, including dialogs and error messages, are externalized. The English strings are provided as the default resource bundles.

Latin-1, DBCS, and BIDI locales are supported by the Eclipse SDK on all reference platforms.

The Eclipse SDK supports GB 18030 (level 1), the Chinese code page standard, on Windows, Linux and the Macintosh.

German and Japanese locales are tested.

Compatibility with Previous Releases

Compatibility of Release 3.7 with 3.6

Eclipse 3.7 will be compatible with Eclipse 3.6 (and all earlier 3.x versions).

API Contract Compatibility: Eclipse SDK 3.7 will be upwards contract-compatible with Eclipse SDK 3.6 except in those areas noted in the Eclipse 3.7 Plug-in Migration Guide . Programs that use affected APIs and extension points will need to be ported to Eclipse SDK 3.7 APIs. Downward contract compatibility is not supported. There is no guarantee that compliance with Eclipse SDK 3.7 APIs would ensure compliance with Eclipse SDK 3.6 APIs. Refer to Evolving Java-based APIs for a discussion of the kinds of API changes that maintain contract compatibility.

Binary (plug-in) Compatibility: Eclipse SDK 3.7 will be upwards binary-compatible with Eclipse SDK 3.6 except in those areas noted in the Eclipse 3.7 Plug-in Migration Guide . Downward plug-in compatibility is not supported. Plug-ins for Eclipse SDK 3.7 will not be usable in Eclipse SDK 3.6. Refer to Evolving Java-based APIs for a discussion of the kinds of API changes that maintain binary compatibility.

Source Compatibility: Eclipse SDK 3.7 will be upwards source-compatible with Eclipse SDK 3.6 except in the areas noted in the Eclipse 3.7 Plug-in Migration Guide . This means that source files written to use Eclipse SDK 3.6 APIs might successfully compile and run against Eclipse SDK 3.7 APIs, although this is not guaranteed. Downward source compatibility is not supported. If source files use new Eclipse SDK APIs, they will not be usable with an earlier version of the Eclipse SDK.

Workspace Compatibility: Eclipse SDK 3.7 will be upwards workspace-compatible with earlier 3.x versions of the Eclipse SDK unless noted. This means that workspaces and projects created with Eclipse SDK 3.6 .. 3.0 can be successfully opened by Eclipse SDK 3.7 and upgraded to a 3.7 workspace. This includes both hidden metadata, which is localized to a particular workspace, as well as metadata files found within a workspace project (e.g., the .project file), which may propagate between workspaces via file copying or team repositories. Individual plug-ins developed for Eclipse SDK 3.7 should provide similar upwards compatibility for their hidden and visible workspace metadata created by earlier versions; 3.7 plug-in developers are responsible for ensuring that their plug-ins recognize metadata from earlier versions and process it appropriately. User interface session state may be discarded when a workspace is upgraded. Downward workspace compatibility is not supported. A workspace created (or opened) by a product based on Eclipse 3.7 will be unusable with a product based on an earlier version of Eclipse. Visible metadata files created (or overwritten) by Eclipse 3.7 will generally be unusable with earlier versions of Eclipse.

Non-compliant usage of API's: All non-API methods and classes, and certainly everything in a package with "internal" in its name or x-internal in the bundle manifest entry, are considered implementation details which may vary between operating environment and are subject to change without notice. Client plug-ins that directly depend on anything other than what is specified in the Eclipse SDK API are inherently unsupportable and receive no guarantees about compatibility within a single release much less with earlier releases. Refer to How to Use the Eclipse API for information about how to write compliant plug-ins.

Table of Contents

Themes and Priorities

The plan items listed below were defined according to contributor requirements and the Eclipse Themes and Priorities set forth by the Eclipse Requirements Council. Each plan item covers a feature or API that is to be added to the Eclipse Project deliverables, or some aspect of the Eclipse Project that is to be improved. Each plan item has its own entry in the Eclipse bugzilla database, with a title and a concise summary (usually a single paragraph) that explains the work item at a suitably high enough level so that everyone can readily understand what the work item entails.

Although there are three mature projects under the top-level Eclipse Project, there is a significant amount of commonality and shared effort between them. In general, many plan items involve coordinated changes to multiple components, and thus attempting to separate the items into sections based on sub-project leads to artificial distinctions between them (e.g., Platform Text vs. JDT Text, Platform Debug vs. JDT Debug, etc.). As such, this plan covers the work of all mature projects under the top level Eclipse Project.

Not all plan items represent the same amount of work; some may be quite large, others, quite small. Although some plan items are for work that is more pressing than others, the plan items appear in no particular order. See the corresponding bugzilla items for up-to-date status information on ongoing work and planned delivery milestones.

The current status of each plan item is noted:

  • Committed plan item - A committed plan item is one that we have decided to address for the release. In bugzilla, this is reflected by having a concrete target milestone assigned.
  • Proposed plan item - A proposed plan item is one that we are considering addressing for the release. Although we are actively investigating it, we are not yet in a position to commit to it, or to say that we won't be able to address it. After due consideration, a proposal will either be committed or deferred. In bugzilla, such items are reflected by having a target milestone "3.7" or "---" assigned.
  • Deferred plan item - A reasonable proposal that will not make it in to this release for some reason is marked as deferred with a brief note as to why it was deferred. Deferred plan items may resurface as committed plan items at a later point. In bugzilla, such items are reflected by having a target milestone "---" assigned.

Platforms

This work is focused on ensuring that Eclipse takes full advantage of all capabilities of the underlying technologies that it is based on, be they operating system, window system, Java or other. This includes support for native accessibility, internationalization and localization capabilities.

  • Committed
    • BIDI enhancements. We will invest in ensuring the Eclipse platform remains a first class basis for products supporting bidirectional text. Areas of investigation include: support for controlling text direction independently from widget orientation, text orientation support in the Text widget, ability to change text orientation at runtime, and stronger support for bidirectional calendars. [SWT] (325994)
    • Support for Webkit on Windows. We will provide support for using Webkit as the embedded browser in Eclipse when running on Windows. Note that the Eclipse platform will not distribute Webkit, but will provide bindings so that it can be used within Eclipse and SWT when available. [SWT] (325995)
    • Complete transition from Motif to GTK. It has become increasingly difficult to add modern new features to the Motif port given that Motif itself has no active development. Support for accessibility, advanced graphics, and transparent shells is unavailable or limited. In addition, there is no available Motif on 64-bit platforms, which has become standard on server class machines. For these reasons we will completely drop support for Motif platforms, and replace them with 64-bit GTK versions. This includes new ports of the platform on AIX and HP-UX. [SWT] (333115)
    • ((new) committed) Adopt new accessibility API. In the 3.6 release, SWT provided new API to support the IAccessible2 standard. This API should be adopted throughout the Eclipse platform user interface to ensure the platform is fully accessible to all users. In addition, SWT will extend its accessibility support to include IAccessibleEditableText, and expand its accessibility testing efforts. [SWT, Platform UI] (325993)
  • Proposed

    None at this time.

  • Deferred
    • ((new) deferred) Add support for Java SE 7 features. The next feature release of Java SE is version 7, which is currently scheduled for July 28, 2011. This release is expected to contain extensions to the Java language, including support for dynamically-typed languages, and other minor language changes (Coin project). Eclipse Java tooling will include initial support for compiling, editing, and launching applications for Java 7 for those parts which have publicly available specifications. [JDT Core, JDT UI] (288548)

      Note: Due to late availability of JSR-292 (Invoke Dynamic) and JSR-334 (Project Coin) and due to the official release date (July 28, 2011) of Java 7 being after 3.7 ships we have deferred Java 7 support to Indigo SR1 (September 2011). The work for the Java 7 features is currently in progress in the 'BETA_JAVA7' branch and we will deliver separate updates for the stable builds in order to provide early access to the Java 7 features for interested parties.

Robustness

As the basis for the entire Eclipse eco-system, the Eclipse SDK must be robust, flexible and secure. This work will address those issues by providing API for missing or currently internal functionality, and focusing on the issues that affect the stability of the platform.

  • Committed
    • ((new) committed) Build at eclipse.org. The current Eclipse project build and test infrastructure runs on proprietary hardware accessible only to certain committers. We will work to migrate the Eclipse project build to run on eclipse.org hardware, so that all committers have equal access to the build environment. At the same time, we will investigate adopting some of the build technology provided by the Eclipse Foundation, such as Hudson for viewing and managing builds. [Rel. Eng., PDE] (325997)
    • ((new) committed) Help servlet API. To allow customized Help front ends, the Eclipse Help System will introduce a set of servlets which publicly expose API for all of the back end functionality. This will include capabilities such as filtering, searching, indexing, navigation, and runtime content. [User Assistance] (319907)
  • Proposed

    None at this time.

  • Deferred
    • ((new) deferred) Resource filter improvements. In the previous release, the concept of resource filters was introduced. We will make improvements to the implementation of filters, including optimizing the storage representation of filters, and providing extensible UI components for working with filters. We will also investigate using resource filters to flatten a hierarchy of resources into a single directory. [Workspace, Platform UI] (325998)

Ease of Use

The Eclipse platform is not lacking in functionality, but sometimes fails to present that functionality to end users in a way that is easy to discover and use. This theme encompasses work to simplify and improve the end user experience, and to keep up with modern user interface input forms such as multi-touch gestures.

  • Committed
    • Multi-touch support. We will add API in SWT for multi-touch events. These events will allow Eclipse applications to react to native multi-touch events on operating system where such events are supported (currently Windows 7 and Mac OS X 10.6). [SWT] (279884)
    • Problems view enhancements. The Problems view supports invoking Quick Fix to automatically resolve problems, but this capability is difficult to discover and use. We will make this option more visible to users, and make it easier to resolve multiple problems at once from the problems view. [Platform UI] (326000)
    • ((new) committed) Help enhancements. We will make a number of enhancements to improve the usability and extensibility of the Eclipse help system. Specific areas of work include improved usability of help search scopes, support for pre-processing steps in help search, and more pervasive support for content filtering. [Platform UA] (326001)
  • Proposed

    None at this time.

  • Deferred

    None at this time.
