Cerberus is a program repair framework that provides the interface to multiple state-of-the art program analysis tools such as Infer and Pulse, as well as program repair tools such as Prophet, Darjeeling, Angelix, F1X etc. Encapsulating the difficulties to setup the infrastructure for program analysis/repair technology, this platform provides the necessary framework to configure a program for analysis/repair. We have integrated multiple defects benchmarks including but not limited to ManyBugs, VulnLoc and Defects4J. This platform also provides the necessary means for researchers to run experiments more efficiently and effectively, with more user-friendly features such as push notifications, and summary extraction.

• Execution of analysis/repair tools on benchmarks of bugs
• Configuration of the environment to execute analysis/repair tools properly on the bugs
• Concurrent execution of multiple analysis/repair tools
• Artifacts are extracted and stored for each experiment
• Push notification once experiments are completed

When cloning the repository ensure that the submodules containing the benchmarks are initialized. There are two ways to do this:

• git clone --recurse-submodules https://github.com/nus-apr/cerberus to init when cloning the project
• or running git submodule init && git submodule update to initialize them post cloning (update can take in a specific path if one wants to initialize only one benchmark)

To ensure that Cerberus has all dependencies one has to run pip install -r requirements.txt before trying to use Cerberus.

Following is a simple snippet for the command to run an experiment from a selected benchmark.

source activate
cerberus -task [analyze/repair] --bug-index=ID  --benchmark=[manybugs/vulnloc] --tool=[cpr/angelix/prophet/f1x]
