BIRT Project Plan for Release 220.127.116.11
< To: BIRT Project
BIRT 18.104.22.168 Project Plan
Draft BIRT Project 22.214.171.124 Plan
Last revised April 13, 2009
This document lays out the feature and API set for the maintenance release of the Eclipse BIRT project after 2.3.2, designated as BIRT 126.96.36.199.
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, plans are posted in an embryonic form and then revised from time to time 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 the projects under the Eclipse BIRT project. Each plan item covers a feature or API that is to be added, or some aspect 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.
Please send comments about this draft plan to the BIRT Developer mailing list.
This maintenance release of BIRT will focus on providing the same downloads as BIRT 2.3.2.
- Wednesday, April 29, 2009 BIRT 188.8.131.52 available
For information about new features assigned to each milestone please refer to the bugzilla database. The bugzilla database will be updated on an ongoing basis as the plan progresses.
Target Operating Environments
In order to remain current, each release of an Eclipse project targets reasonably current versions of underlying operating environments and other Eclipse projects on which it depends.
Most of Eclipse, and all of BIRT, is “pure” Java™ code and has no direct dependence on the underlying operating system. For BIRT, the chief dependence is on the Eclipse Platform, Graphical Editor Framework (GEF), Modeling Framework (EMF), and on the Java 2 Platform that runs it.
The Eclipse BIRT 184.108.40.206 release depends on the following compatibility stack:
BIRT 220.127.116.11 Reference Stack for JDK 1.5
- Java 2 platform Java Development Kit (JDK) 1.5
- Eclipse Platform Runtime Binary 3.4
- Graphical Editor Framework (GEF) Runtime 3.2
- Eclipse Modeling Framework (EMF) 2.3
- Data Tools Platform Project 1.6 (DTP)
- Web Tools Project (WTP) 3.4
BIRT 18.104.22.168 Reference Stack for JDK 1.6 (This is only a proposal and depends on whether various projects provide support for JDK 1.6)
- Java 2 platform Java Development Kit (JDK) 1.6
- Eclipse Platform Runtime Binary <TBD>
- Graphical Editor Framework (GEF) Runtime <TBD>
- Eclipse Modeling Framework (EMF) <TBD>
- Data Tools Platform Project (DTP) <TBD>
- Web Tools Project (WTP) <TBD>
The Eclipse Platform and BIRT run in a variety of operating environments. Testing is focused on a handful of popular combinations of operating system and Java 2 Platform; these are our reference platforms. Eclipse BIRT 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 BIRT on non-reference platforms that cannot be recreated on any reference platform will be given lower priority than problems with running Eclipse BIRT on a reference platform.
For BIRT 22.214.171.124, the project team plans to tests and validate the following reference platforms:

The English strings for BIRT are provided as the default resource bundles. Translations are provided with this release for French (fr_FR), German (de_DE), Spanish (es_ES), Japanese (ja_JP), Simplified Chinese (zh_CN), and Korean (ko_KR).
Community Tested Operating Environments
Due to the finite resources available to the BIRT project, we would like to encourage the BIRT community to contribute to testing BIRT in operating environments other than those listed as target operating environments for the 18.104.22.168 release of BIRT and to share this information with the rest of the community. If you have been able to test BIRT in a non-targeted operating environment please take a few minutes to update this wiki page and report this information there. If you have encountered bugs during your testing, please report these in bugzilla.
Compatibility with Previous Releases
BIRT 22.214.171.124 will be compatible with earlier versions of BIRT to the greatest extent possible. The nature and scope of some of the key plan items for BIRT 126.96.36.199 are such that the only feasible solutions might break compatibility. In other regards, BIRT 188.8.131.52 will be compatible with 2.x and 1.x. We also aim to minimize the effort required to port an existing plug-in to the 184.108.40.206 APIs.
Compatibility of Release 220.127.116.11 with 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1.x, 2.1, 2.0.x and 1.x
BIRT 18.104.22.168 will be compatible with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x unless noted. The detailed compatibility statement is listed below. In this statement, "BIRT" refers to all BIRT components: BIRT Report Framework, BIRT Runtime, and BIRT Chart SDK.
API Contract Compatibility: BIRT 22.214.171.124 will be upwards contract-compatible with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x to the greatest extent possible. All incompatibility exceptions will be documented. Downward contract compatibility is not supported. There is no guarantee that compliance with BIRT 126.96.36.199 APIs will ensure compliance with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x or 1.x APIs. Refer to general Eclipse document on Evolving APIs for a discussion of the kinds of API changes that maintain contract compatibility.
The BIRT Chart UI API 188.8.131.52 is compatible with the 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x API but not compatible with the v1.x APIs due to a full redesign of the Chart UI in the BIRT 2.0 release.
Binary (plug-in) Compatibility: The BIRT 184.108.40.206 plug-in framework will be upwards binary-compatible with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x plug-ins to the greatest extent possible. Downward plug-in compatibility is not supported. Plug-ins for BIRT 220.127.116.11 will not be usable in BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x or 1.x. Extension plug-ins for BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x will be upwards binary-compatible with BIRT 18.104.22.168.
Source Compatibility: BIRT 22.214.171.124 will be upwards source-compatible with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x to the greatest extent possible. This means that source files written to use BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x or 1.x APIs will successfully compile and run against BIRT 126.96.36.199 APIs. Downward source compatibility is not supported. If source files use new BIRT APIs, they will not be usable with an earlier version of BIRT.
Report Design Compatibility: BIRT 188.8.131.52 will be upwards report design compatible with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x and 1.x unless noted. This means that reports created with BIRT 2.3.2, 2.3.1, 2.3, 2.2.2, 2.2.1, 2.2, 2.1, 2.1.x, 2.0.x or 1.x can be successfully opened by BIRT 184.108.40.206 and upgraded to a 220.127.116.11 format.
Non-compliant usage of API's: All non-API methods and classes, and certainly everything in a package with "internal" in its name, 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 BIRT API are inherently unsupportable and receive no guarantees about compatibility within a single release much less with an earlier releases.
BIRT 18.104.22.168 is the third maintenance release in the BIRT 2.3 release series and is intended to be narrow in scope. The 22.214.171.124 release is focused on addressing a critical bug identified by the community.
BIRT 126.96.36.199 will address a critical defect reported by the community. The defect targeted for resolution in this release is:-
Spaces not supported in classpath configured with WEBAPP_CLASSPATH_KEY - This project looks at supporting spaces in the classpath when it is set using the WEBAPP_CLASSPATH_KEY key. [Bugzilla ID : 266914]
