PRFC: Program Repair combining Fix patterns and Code language models

This repo contains both the correct patches generated by our study along with the code used to run the experiment.

Prerequisites

1. Defects4J

Install Defects4J from https://github.com/rjust/defects4j 
export PATH=$PATH:"path2defects4j"/framework/bin

2. JDK 1.8

JDK 1.8 for Defects4J
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Plausible patches generation

Example usage to run PRFC: bug_id: The bug you want to fix. skip_v: Skip the patch validation step, re_rank: Use the patch rerank step, perfect: Use the perfect fault information.

python experiment.py --bug_id Chart-1 \
               --skip_v \
               --re_rank \
               --perfect
