Open Source Debuggers

Lumbermill is a visual log processing and distribution center for Log4j and (in 2.0) java.util.logging (JSR47). It is a Swing/GUI standalone application that supports viewing and archiving of log events.

Portable emulator for Pokémon-Mini. Last version: 0.60 (16 June 2015) Check Wiki for platform dependencies and other information.

GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.

CTrace is a multi-threaded trace debug library written in C. It provides a simple, fast, well documented trace utility for applications and as such is especially suitable for use in real-time embedded applications.

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

A Zilog Z80 simulator, debugger and profiler tailored for ZX Spectrum development (but generic enough to be used with other platforms)

JSGB is a Nintendo GameBoy emulator. Written in JavaScript and HTML5. Integrates a debugger with breakpoints support, memory, viewer and more... You can test it here: www.codebase.es/jsgb/?v=0.02

Entex Adventure Vision emulator with debugging capabilities. Latest version: 1.0 (March 16, 2013) For now the emulator is hardcoded with Qt, in future this will be changed to make the project more portable. Short F.A.Q. ------------------ Q: Emulator can't reach 100% emulation with sound enabled! A: Fiddle with the Sound buffer size inside "Options..."

Seksen is a GUI based 8086, 80186 emulator and debugger in Java.

BT-Sim is a BlueTooth simulator on a HCI level. The project alows to develop and test BT applications without using real BT hardware. It works in particular with PalmSource's Palm OS Simulator.

CoDeK - Java Concurrent Development frameworK is a very simple, open-source, academic java library aimed to help the development of Java multi-threading concurrent applications.

Cricket Cage automatically creates JUnit TestCases for repeatable bugs and test scenarios. Include Cricket Cage's AspectJ code to install a code generator, then run the program to generate the TestCase. Finally, add the test case to your build.xml.

The goal of this project is to develop the OS-independent, obtrusive, customizable, extensible, generic logging and tracing software mechanism.

Allows JDBC resources to be monitored. You can see when java.sql objects are being opened and closed and can see the line of code where a resource that is still open was originally opened.

ALF, The Automated Logging Framework, is a native logging framework for Java with the unique advantage of supporting automated method tracing. This platform-independent library allows developers to debug their applications quickly without adding code

Bean Bowl is the a fun and useful Java lab, allowing you to play around with Java classes and objects using direct manipulation techniques instead of writing long main() methods. Use it either as an application or as a GUI component framework for you own

This is a simple, modular PHP class designed to record execution time benchmarks throughout different parts of a script. Compatible with virtually any PHP script, the code can be added/removed quickly and with ease. Accurate to the microsecond.

Bugkilla is a set of java tools for the functional test of J2EE Web Applications. Specification and execution of tests will be automated for web front end and business logic layer. One goal is to integrate with existing frameworks and tools.

Yet another logger. Take a close look at it: It is very easy to use, very unified and extendable. You may attach your favourite set of loggers to this logger, and you still use only one API! This Java logger is used throughout the COMJAT.NET systems.

This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

The Logging Framework supports stream-like usability, extensibility, portability, type-safety, allows enabling/disabling certain parts or fully at compile time and dependent on the configuration also at runtime and avoids macro-related pitfalls.

CorbaTrace is a helpful tool for tracing communications beetween Corba objects. Once CorbaTrace is installed, remote calls are intercepted and informations are stored in XML files. So, you will be able to apply filters and get XMI files to see the commu

An eclipse plugin providing tail in view component.

Follow is a simple Java application which allows a user to monitor several log files concurrently. The source for this project is now being maintained at http://hallwaytech.github.com/follow

For C (and CPP obviously): Include a fast and tiny RAM-tracing feature for Real-Time (RT) debugging purposes. >> ONLY FOR DEBUGGING << Very much faster than printf-debugging, which may result in unforseen results in an RT environement.
