Project Plan For Target Management, version 3.4


Last revised 14:00 CET February 2, 2012.

Please send comments about this plan to the developer mailing list (subscription info).

The Target Management Project provides data models, frameworks and tools for working with remote computer systems. The main deliverable is the Remote System Explorer (RSE), a feature-rich integrated perspective and toolkit for seamlessly working on remote systems. Besides that, we deliver flexible, re-usable components for Networking and Target Management that run stand-alone or integrated with RSE.

In terms of interfaces to other Eclipse projects, we provide an Eclipse Filesystem (EFS) provider to allow remote resources be mapped into an Eclipse Workspace. The DLTK and CDT projects are other Eclipse projects known to integrate with Target Management. PTP and PDT can use TM services via the underlying DLTK and CDT layers. Several Eclipse Packages include TM (The Eclipse for Web package, for instance, includes the TM Terminal).

Target Environments

In order to remain current, each Eclipse release is designed to run on reasonably current versions of the underlying operating environments.

The Target Management Project 3.4 depends upon on the Eclipse Platform 4.2 or 3.8. For this release, the RSE sources will mostly be written and compiled against version 1.4.2 of the Java Platform APIs (i.e., Java 2 Platform, Release 1.4.2 SE), and designed to run on version 1.4.2 of the Java Runtime Environment, Standard Edition except for the following components, which are compiled on and running against Java 5: FTP, Telnet and Import/Export.

The Target Management deliverables will be tested and validated against a subset of the reference platforms listed in the Eclipse Platform 4.2 Project Plan (this list is updated over the course of the release cycle).

Target Management Reference Platforms
Operating system OS version Processor architecture Window system Java 2 Platform
Microsoft Windows XP SP3 x86 32-bit Win32 IBM Java 6 SR9
Microsoft Windows 7 SP1 x86 64-bit Win32 Oracle Java 6 Update 27
Red Hat Enterprise Linux WS 5 update 6 x86 64-bit GTK Oracle Java 6 Update 27
for Linux x86
SUSE Linux Enterprise Desktop 11.2 x86 64-bit GTK Oracle Java 6 Update 27
Apple Mac OS X (Secondary, see below) 10.6.8 Universal 64-bit Cocoa Apple Java 10.6 Update 5

Apple Mac OS X 10.5 is considered a "secondary" Reference Platform meaning that it does receive some amount of systematic testing but doesn't enjoy quite the same priority for bug fixes as the other Platforms.

Eclipse and Target Management undoubtedly run 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 Target Management on a non-reference platform that cannot be recreated on any reference platform will be given lower priority than problems with running Target Management on a reference platform.

Although untested, Target Management should work fine on other OSes that support the same window system. For more details, see the Eclipse Project Plan 4.2 Reference Platforms.

Datastore Agent Reference Platforms

The Datastore protocol is the default protocol shipped with RSE for accessing remote file systems, process info and shells. It requires a Datastore server (agent) running on the remote system. This Datastore agent is shipped as plain Java Source Code together with the RSE distribution. It should run fine on any Java Platform, with additional Data Miner Plug-ins that may be OS specific.

We will test and verify the Datastore agent on the following Reference Platforms, which are a subset of the Platforms we test the RSE UI on:

  • Red Hat Enterprise Linux 4, Intel x86, Oracle 1.5.0_14 VM
  • SUSE Linux Enterprise Server 10, Intel x86, IBM 1.4.2 sr 7 VM
  • Apple Mac OS X 10.5, Power, Apple J2SE 5 sr 4 VM


The Remote System Explorer is designed as the basis for internationalized products. The user interface elements provided by the RSE components, including dialogs and error messages, are externalized. The English strings are provided as the default resource bundles. The default bundles will be localized to a subset of those locales offered by the Platform. This plan will be updated to indicate which locales will be provided and the timeframe for availability.

Compatibility with Previous Releases

Target Management 3.4 will be backward compatible with TM 3.3.

API Contract Compatibility: Target Management 3.4 will be compatible with TM 3.3 as per the constraints documented in the TM 3.3 API Docs.

Binary (plug-in) Compatibility: Target Management 3.4 will be binary compatible with TM 3.3.

Source Compatibility: Target Management 3.4 will likely not be source compatible with TM 3.3.

Workspace Compatibility: We intend to keep Target Management 3.4 upwards workspace-compatible with TM 3.3 unless noted. This means that workspaces and projects created with TM 3.3 can be successfully opened by Target Management 3.4 and upgraded to a 3.4 workspace. This includes especially TM 3.3 connection definitions, which may propagate between workspaces via file copying or team repositories. 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 TM 3.4 may be unusable with a product based on TM 3.3.

API Contract

APIs published for the Target Management 3.4 release will be carefully reviewed prior to release, making use of "internal" packages for unsupported and variable implementation classes. Client plug-ins that directly depend on anything other than what is specified in the published API are inherently unsupportable and receive no guarantees about future compatibility. Refer to How to Use the Eclipse API for information about how to write compliant plug-ins.

Themes and Priorities

Plan items listed below were defined according to contributor requirements, but in accordance with the Target Management Use Cases Document 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 Target Management deliverables, or some aspect of the Target Management 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. 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 "3.4" 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 "Future" or "---" assigned.

Improve Release Engineering

For the constantly growing TM code size and committer base, it is important to have a reliable but easy-to-use release engineering system. Required features include automatic signing and adoption of Orbit, easy promoting to the Eclipse Servers and Juno, running automated unit tests with automatic reporting of test failures to the mailing lists, ability and description for running the releng build on any adopter's system. We intend to adopt Tycho as the de-facto standard build system at Eclipse in this release, and have our main builds run on the Eclipse Hudson instance. In bugzilla, items related to this theme are tagged with "[releng]" in the Summary (query: all [releng] open).

  • Proposed

    • [releng] The RSE "feature micro version" has not been updated for Juno SR2 [402327] (target milestone: ---)
    • [releng] Integrate RSE-Useractions into RSE-Runtime [236122] (target milestone: ---)
    • [releng][wince] Trying to install WinCE on Linux with P2 gives odd error messages [236026] (target milestone: ---)

Improve Unittest Coverage

As the TM Codebase is growing, it is important to secure its functionality with unit tests against regressions. Since large portions of RSE especially are UI code, there should be an automated UI test suite run every night. Tests should automatically run on all supported host platforms against all supported target platforms. Adopters should be able to run a TM test suite on their own systems easily, and configure it for sanity checking or compliance testing their own connector plug-ins. In bugzilla, these items are tagged with "[testing]" in the Summary (query: all [testing] open).

  • Committed

    • [testing] HostMoveTest.testMoveManyUp() sometimes fails on Linux with SWT: "Index out of bounds" [315054] (target milestone: 3.4 M6)
    • [testing] HostMoveTest.testMoveOneDown fails on Win7 64bit [335930] (target milestone: 3.4 M6)
  • Proposed

    • [testing] Add an RSE Unittest for SimpleCommandOperation [332615] (target milestone: ---)
    • [testing][local] 5 unittest failures in archive suite on Windows 7 64bit [335929] (target milestone: ---)
    • [testing] Error renaming in testCopyVirtualBatchToVirtualFileLevelOne [348819] (target milestone: ---)
  • Deferred

    • [testing][regression] Some DStore Archive Testcases fail [230917] (target milestone: Future)

Run on Eclipse 4.x

Eclipse 4.2 is the designate mainstream of Eclipse Platform development. The TM project is committed to developing, running and testing on the Eclipse 4.2 platform, and fixing defects as they are discovered. In bugzilla, items related to Eclipse 4.x migration are tagged with "[4x]" in the Summary (query: all [testing] open).

  • Committed

    • [4x][br][security] Adopt Equinox Secure Storage for RSE Passwords [225320] (target milestone: 3.4 M6)


Bug fixes for improved robustness, stability and usability are part of ongoing maintenance. Besides that, here are some larger features and bugs that we plan to address in the next release cycle until 3.4 M7, but are not categorized into one of the themes above. <br> In order not to overload the project plan with less important items, only those marked with a "plan" keyword will be added to the project plan. The pool of known items to add to the plan can be found from the associated queries (query: all open committed, proposed, deferred ).
