<hr/>
<p>
The goal of the Equinox project is to be a first class OSGi community and foster the vision of Eclipse
as a landscape of bundles. As part of this, it is responsible for developing and delivering the OSGi
framework implementation used for all of Eclipse.
</p><p>
This plan is for Equinox as part of the
Galileo release in 2009 and attempts to balance the evolution of the technology with the increased
need for testing and robustness.
</p><p>
This release of Equinox tackles a number of challenges. As OSGi gains more visibility and Equinox
more use, new use-cases and drivers come to the fore -- people
are pushing the technology and implementation in new directions. 2009 will also see the release of a new
OSGi spec revision. Equinox will implement this spec and several of the new services. Equinox will also
deliver runtime technologies including the p2 provisioning platform, the extension registry, integrated security
support as well as support for OSGi on on the server.

</ul>
</div><p><a href="#toc">Table of Contents</a></p><h2><a name="target_environments">Target Environments</a></h2><div>
<p>In order to remain current, each Equinox release targets reasonably current
operating environments. </p>
<p>Most of Equinox 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 of Equinox 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 1.0, J2SE 1.3 and 1.4,
etc.). </p>
<p> In general, the 3.5 release of Equinox is developed for a mix
of J2ME Foundation 1.0 and 1.1 JREs. Certain bundles do however use facilities in more
recent JRE versions. In such cases, the associated capabilities are available when
running on the required JRE. </p>
<p> <a href="#Appendix1">Appendix 1</a> contains a table that indicates the class
library level required for each bundle. </p>
<p>There are many different implementations of the Java Platform running atop
a variety of operating systems. We focus Equinox testing on a handful of
popular combinations of operating system and Java Platform; these are our <em>reference
platforms</em>. Equinox undoubtedly runs fine in many operating environments
beyond the reference platforms we test, including those using Java6 VMs. However,
since we do not systematically test them we cannot vouch for them. Problems
encountered when running Equinox on a non-reference platform that cannot be
recreated on any reference platform will be given lower priority than problems
with running Equinox on a reference platform.</p>
<p> Equinox 3.5 is tested and validated on the following reference platforms

<p>Because Java 1.4.2 and Java5 based platforms are used for most Eclipse development,
those platforms are listed here. Although there are teams doing some Java 6
based development we have not included specific Java6 VMs, since they have
not yet received the general level of testing we require. <i>We expect that
Equinox works fine on other current Java VMs and OSes but we cannot flag these as reference
platforms without significant community support for testing them. Especially in areas such as
the launcher and OS security integration.</i></p>
<p>As Equinox is largely headless, there are very few dependencies on window systems.
Where there are UI elements (e.g., in the p2 UI), these elements will work on any configuration
supported by SWT.</p>
</div><h3>Internationalization</h3>
<p>Equinox is designed as the basis for internationalized products. The
user interface elements provided by Equinox components, including dialogs
and error messages, are externalized. The English strings are provided as the
default resource bundles.</p>
<p>Latin-1 and DBCS locales are supported by Equinox on all reference platforms;
BIDI locales are supported by Equinox everywhere but on Motif.</p>
<p>Equinox supports GB 18030 (level 1), the Chinese code page standard,
on Windows XP and 2000, Linux/GTK and the Macintosh.</p>
<p>German and Japanese locales are tested.</p>
<p><a href="#toc">Table of Contents</a></p><h2><a name="compatibility">Compatibility with Previous Releases</a></h2><div>
<p>Equinox 3.5 will be backward compatible with Equinox 3.4 (and, hence, with 3.3, 3.2, 3.1
and 3.0).</p>
<p> <strong>API Contract Compatibility:</strong> Equinox 3.5 will be upwards
contract-compatible with Equinox 3.4 except in those areas noted in the <a href="http://wiki.eclipse.org/Equinox_Galileo_Porting_Guide" target="_top"> <em>Equinox
3.5 Migration Guide</em></a>. Programs that use affected APIs and extension
points will need to be ported to Equinox 3.5 APIs. Downward contract compatibility
is not supported. There is no guarantee that compliance with Equinox 3.5
APIs would ensure compliance with Equinox 3.4 APIs. Refer to <a href="http://wiki.eclipse.org/index.php/Evolving_Java-based_APIs"> <em>Evolving
Java-based APIs</em> </a> for a discussion of the kinds of API changes that
maintain contract compatibility. </p>
<p><strong>Binary (bundle) Compatibility:</strong> Equinox 3.5 will be upwards
binary-compatible with Equinox 3.4 except in those areas noted in the <a href="http://wiki.eclipse.org/Equinox_Galileo_Porting_Guide" target="_top"> <em>Equinox
3.5 Migration Guide</em></a>. Downward bundle compatibility is not
supported. Bundles for Equinox 3.5 will not in general be usable in Equinox 3.4.
Refer to <a href="http://wiki.eclipse.org/index.php/Evolving_Java-based_APIs"> <em>Evolving
Java-based APIs</em> </a> for a discussion of the kinds of API changes that
maintain binary compatibility. </p>
<p><strong>Source Compatibility:</strong> Equinox 3.5 will be upwards source-compatible
with Equinox 3.4 except in the areas noted in the <a href="http://wiki.eclipse.org/Equinox_Galileo_Porting_Guide" target="_top"> <em>Equinox
3.5 Migration Guide</em></a>. This means that source files written
to use Equinox 3.4 APIs might successfully compile and run against Equinox
3.5 APIs, although this is not guaranteed. Downward source compatibility
is not supported. If source files use new Equinox APIs, they will not be
usable with an earlier version of Equinox. </p>
<p><strong>Non-compliant usage of API's</strong>: All non-API methods and classes,
and certainly everything in a package with "internal" in its name or those
packages marked with "x-internal=true" or with "x-friends" annotations,
are considered implementation details which may vary between operating environment
and are subject to change without notice. Client bundles that directly depend
on anything other than what is specified in the Equinox API are inherently
unsupportable and receive no guarantees about compatibility within a single
release much less with earlier releases. Refer to <a href="http://www.eclipse.org/articles/Article-API%20use/eclipse-api-usage-rules.html"> <em>How
to Use the Eclipse API</em> </a> for information about how to write compliant
bundles. </p>
</div><p><a href="#toc">Table of Contents</a></p><h2><a name="themes_and_priorities">Themes and Priorities</a></h2><div>
<p>Plan items listed below were defined according to
contributor requirements and the Eclipse <a href="http://wiki.eclipse.org/RequirementsCouncilThemesAndPriorities">
Themes and Priorities</a>
set forth by the Eclipse Requirements Council.
Each plan item covers a feature or API that is to be added to the
Equinox deliverables, or some aspect of the Equinox 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.
</p>
<p>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.
</p>
<p>The current status of each plan item is noted:
</p>
<ul>
<li><b>Committed</b> 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.</li>
<li><b>Proposed</b> 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 "3.5" or "---" assigned.</li>
<li><b>Deferred</b> 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" assigned.</li>
</ul>
</div><h3>Scalability and Performance</h3><p>
New usage scenarios for Equinox require it to be faster, smaller, bigger, ...
The technology needs to scale up or down to allow Equinox to scale down to small embedded environments as well
as scaling up to large server environments.
Monitor overall performance and memory consumption which includes the addition of new performance tests for new features.
</p><ul><li><b>Committed</b><ul>
<li><strong>Framework</strong>
<ul>
<li>Investigate places where we can rid the framework of bulky and unnecessary abstraction layers to reduce size and improve performance (service registry abstraction, resolver abstraction etc.).

<li><strong>Framework</strong>
<ul>
<li><strong>Improve performance of the "uses" directive in the resolver</strong> - The OSGi specification provides a modularity framework that ensures consist class spaces
when multiple versions of a package is available. In order to ensure a consist class space
exporters must specify what other packages they "use" with the "uses"
directive. The Equinox Framework correctly implements the "uses" directive but
it has been found to cause performance issues in the resolver.

Equinox has become the base for a wide range of platform from embedded to server to desktop and rich client applications.
These new scenarios bring new requirements on the execution of Equinox as well as on the programming of its API.
The Equinox team will improve the overall robustness by providing APIs for clients where needed and fixing critical bugs.
There will also be a focused effort on testability and enhancing the automated test suites.

Several bugs have been reported about thread safety issues when running bundle lifecycle
operations from multiple threads. This plan item is to review and fix thread safety issues in the
Framework. <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=247636">Bug 247636</a></li>

<li><strong>Improved path and URL support</strong> - UNC and URL encoding frequently cause
problems. We will identify best practices and coding patterns and make them available for others to use
as well as use them throughout the Equinox code base.

<li><strong>Framework</strong>
<ul>
<li><strong>API to contribute and get Execution Environment Profiles</strong> - The Equinox
Framework currently has a set of built-in and supported Execution Environment profiles
(e.g. J2SE-1.4, J2SE-1.5 etc.). These profiles are used internally be the Framework to
define the packages exported by the running VM. Tooling also needs access to the
Execution Environments to place proper visibility rules on the configured VM for a
project. API is needed to provide a way to contribute and get the available
Execution Environment profiles
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=240724">Bug 240724</a></li>
<li><strong>WebStart support on latest VMs</strong> - The WebStart support in
Equinox needs to be enhanced to load resources outside the jnlp class loader.
The current WebStart support makes invalid assumptions on the resources cached
by the jnlp class loader.
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=244311">Bug 244311</a></li>
<li><strong>Pass arguments to a running Eclipse application.</strong> A protocol and
framework are needed to allow arguments to be passed from the native launcher to a
running instance of eclipse.

<li><strong>Compendium</strong>
<ul>
<li><strong>Logging</strong> To date the platform has placed tight restrictions on the
configuration of existing 3rd party logging frameworks. The goal here is to lift the most
important of these restrictions and provide a modular and OSGi friendly integrated approach.
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=248794">Bug 248794</a></li>
</ul>
</li>
<li><strong>Server-side</strong>
<ul>
<li><strong>Support undeploying the servlet bridge</strong> - Ensure the servletbridge
provides a clean deploy and undeploy environment. The servletbridge does not undeploy
cleanly because of its use of a URLClassloader and a restriction on how the VMs
"jar"URLConnection holds open the underlying jar file. In particular this prevents us
from deleting the framework and servletbridge extension bundles when undeploying.
A more deployment friendly class loader is needed here and will likely be useful elsewhere
when launching equinox.

<li><strong>p2</strong>
<ul>
<li><strong>Improve the robustness of the download operations</strong>
Several parts of p2 download files (repo content, artifacts, etc.). Even though
the robustness is reasonable, there are still room for improvement by providing
the ability to checksum the files being downloaded, retry strategies, etc.
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=248602">Bug 248602</a></li>
<li><strong>Improve the robustness of the installation in case of failure.</strong>
There are cases where a failure during certain phase of the installation will
cause the system to be left in an inconsistent state (bogus entries in
bundles.info, config.ini, etc.).
We need to make the transitioning from an install to another robust.
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=248594">Bug 248594</a></li>
<li><strong>Investigate the use of alternate http clients.</strong>
There exist several alternative HTTP client implentations (e.g., Apache, Jetty, ...). Investigate
if p2 would benefit from switching to one of these clients in the SDK, the Installer and the
Admin UI. <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=220240">Bug 220240</a></li>

The diversity of Equinox poses a significant problem to end-users and developers alike.
Equinox is extremely flexible and configurable. This makes the hard things possible but in some cases the simple things are
not as simple as they might be. The Equinox team will make it easier for users to get the relevant pieces of function,
install it on their systems, and configure it for their use. Where there is UI, attention will be paid to making it simple and
natural to use. We will also make it easier for developers to use our APIs.

</ul>
<ul>
<li><strong>Simplify the addition of repository content</strong> p2 is powered by metadata and artifact
repositories. Unlike other systems, p2's repositories are solely API driven (there is no schema, and perhaps
no XML). As such, we need reasonable tooling and mechanisms to facilitate the publishing of repository content.

Eclipse is evolving quickly. New features in the next OSGi specification R4.2 and e4 will drive numerous changes throughout the Equinox
project. Considerable effort will be put into updating Equinox to accomodate and exploit these new scenarios.
</p><ul><li><b>Committed</b><ul>
<li><strong>OSGi standards participation</strong>
<ul>
<li>The OSGi Alliance, in collaboration with Equinox and other open source communities,
is currently revising the Core specifications. As the reference implementation for
several parts of the OSGi specifications, Equinox will be updated to implement these
new features and changes to the spec.
