Development Environment (Committers and Contributors)
Checking out the code (Committers and Contributors)
The GEF source code (i.e. Draw3d and GEF (MVC) 3.x as well as Zest 1.x) is located in the GEF Git repository. TODO: document how to clone the repository using Git/EGit here. Further describe master, maintenance branch structure. you may check out all plug-ins located in the root folder.
Setting up the workspace
Eclipse Target Platform
Target definition files are provided by the
org.eclipse.gef.target project, which includes a respective Eclipse SDK.
GEF uses PDE API tooling to guarantee proper handling of version numbering as well as API compatibility, so without definition of an API baseline you will see compile problems after having checked out the code. API-baselines are provided by the
org.eclipse.gef.baseline project. You may define them by going to Preferences -> Plug-in Development -> API Baselines, then choose to select "Add Baseline..." and point to the
plugins sub-folder of an API baseline located in the baselines project (note that the dialog browses the file system instead of the workspace, so you will have to point into the respective folder in your local Git repository).
Code Style (Formatting)
The GEF project uses the default built-in Eclipse formatter. Java-Editor Save-Actions are defined for each Java-nature plug-in of the GEF project to preserve formatting as well as organization of imports upon code changes.
Running a headless build locally
Beginning with GEF 3.8.0M5, GEF has adopted a Maven/Tycho-based build infrastructure (see bug #363394 for details). With the Maven Integration installed, the headless build that is executed by a Hudson job can also be executed in the local workspace. Make sure you have checked out all projects listed within the Team Project Set provided above. Then easily run the build by right-clicking the
pom.xml file located within the
org.eclipse.gef.releng project, and selecting 'Run As -> Maven install'. As a result of the build, an update-site will be created in the
target sub-folder of the
Producing a patch
Committing code (Committers Only)
The GEF development team uses the following format for commit comments:
Format: [<bug-id>] <affected-branch> <contributor> <commit-date> <bug-summary>
Example:  gef-head crevells 071221 Make GEF's snapping and tools extensible to allow moving shapes with arrow keys
While the branch the code was committed to, the originator of the contribution and the commit date may possibly be redundant (since we are duplicating the information in CVS and they are already in the history), but it has been found useful to easily figure out what the actual change was. Note that in case of a third-party contribution (patch) the name of the contributor and not the committer name will be included in the comment.
Bug Handling Policy
When working with bugzillas, the following guidelines should be regarded.
When resolving bugzillas, it should be stated how the bug is verified. Preferably this is a JUnit test. Alternatively, the bugzilla will say that the defect can be reproduced in the Logic example and you can demonstrate the fix working in the logic example (or other examples using GEF). If the bug is trivial or obvious and does not require a test, we can just state this in the Bugzilla too.
Despite selecting a component, a bugzilla may be classified to more precisely specify, what part of the GEF API is concerned. We use categories for this issue, which will be stated as a [<category_name>] prefix within the bugzilla's summary. The list of currently used categories is:
- [TVT] - Translation Verification Tests
