Current status

• Targeted release: Fedora 12

• Percentage of completion: 50%

Detailed Description

Allow developers to launch SystemTap scripts on their C/C++ projects directly from Eclipse. Provides a launch wizard for easy launches, as well as a few prebuilt scripts. The included graphical viewing program generates a program graph displaying time information for function calls. Also comes with the ability to annotate functions, allowing the user to mark graph nodes and displaying user-specified, function-specific information on the graph.

Benefit to Fedora

Makes it easier for developers to use SystemTap, and provides a neat way to graphically profile C/C++ projects developed through Fedora Eclipse.

Scope

Adds a small plugin family to Fedora Eclipse

Test Plan

1. Write JUnit tests
2. Improve test coverage of core components to 80%
3. Stress test to find limit on size of C/C++ binary that can be probed

User Experience

1. Users of Fedora Eclipse's CDT tools will be able to select Profile As and select one of several prebuilt SystemTap scripts, or launch a custom script through the script launch Wizard.
2. Sample videos will be posted soon.
