SWORD: A Fast Concurrency Bug Detection for The Whole Program

This project is no longer under maintainance, apologies for the terrible code quality. There are a lot of follow-ups going on, if you have any specific question regarding this project, email me.

Introduction

SWORD is an interactive Eclipse Plugin to detect data races and deadlocks in Java programs. The fundamental techniques (i.e., points-to analysis and static happens-before analysis) that SWORD adopts are in:

[FSE'16] "ECHO: Instantaneous In Situ Race Detection in the IDE"

[PLDI'18] "D4: Fast Concurrency Debugging with Parallel Differential Analysis"

Software Dependencies

• Java 1.8
• Eclipse PDE

Quick Start

1. Clone the project
2. Import all the projects in Eclipse and build.

How To Use

Start The Detection

1. Select a main class in the Package Explorer
2. Right click ASER -> SWORD to start the detection.

SWORD Views

Goto Windows -> Show View -> Others to open the ECHO views (i.e., ECHO Race List, ECHO Deadlock List, ECHO Concurrency Relation):

• SWORD Race List: contains all the detected races with a pair of read/write accesses and their possible traces
• SWORD Deadlock List: contains all the detected deadlocks with a pair of nested locks and their possible traces
• SWORD Concurrency Relation: contains all read and write operations that may happen in parallel

Large Benchmarks

The github repo includes 6 large, real-world Java projects. To test the practicality of SWORD on these projects, you can import them into your target workspace.
