BugZoo

Build Status GitQ PyPI version Python versions

BugZoo is a decentralised platform for distributing, reproducing, and interacting with historical software bugs. BugZoo is designed to support both software engineering researchers as well as developers of tools for program testing, analysis and repair.

Under the hood, BugZoo uses Docker containers to provide a controlled, sterile environment for safely interacting with historical software bugs. BugZoo provides several advantages over the use of monolithic virtual machines (e.g., ManyBugs VM):

  • By using containerisation instead of virtualisation, BugZoo can ensure reproducibility with minimal sacrifice to performance, allowing you to run bigger experiments faster.
  • Since containers can be spawned in under a second, a safe, idempotent execution environment can be realistically provided for every test suite evaluation.
  • Each historical bug is provided as its own minimal Docker container image. There are no assumptions that bug containers should be capable of running other software, such as a testing or repair tool that is being evaluated as part of an experiment. BugZoo avoids the inevitable "DLL hell" that arises from attempting to mix bugs and tools by transforming tools into portable binaries and mounting them in the execution environment at run-time.
  • Thanks to their minimal nature and Docker's layer-based image caching, prebuilt datasets of historical bugs can be downloaded quickly and easily.

Features

  • A simple but powerful command-line interface for building, downloading and interacting with historical bugs.
  • A Python interface for complex, structured interactions with historical bugs: execute specific tests, compute line coverage, apply patches, compile with certain flags, and more.
  • A powerful underlying RESTful API that can be used to add BugZoo bindings to your own favourite language.
  • A decentralised architecture that lets you share your tools and datasets of historical bugs on the BugZoo platform without giving up ownership or control. Adding BugZoo support to your dataset of tool is as simple as adding a .bugzoo.yml file to your project.

Installation

We recommend using pipenv to install BugZoo, although you may simply use pip3 instead:

$ pipenv install bugzoo

BugZoo supports Python >= 3.5.

Getting Started

Since BugZoo is a decentralised platform for sharing and interacting with historical bugs (and not itself a dataset of bugs), you'll need to add several bugs and tools to your installation. Bugs and tools are usually provided to BugZoo by remote, public Git repositories. Adding a source of bugs or tools to your installation can be done via the bugzoo source add [name] [url] command:

$ bugzoo source add manybugs https://github.com/squaresLab/ManyBugs

Note that sources do not necessarily have to be remote, public Git repositories: they can also be provided by local directories.

$ git clone https://github.com/squaresLab/ManyBugs path/to/manybugs
$ bugzoo source add another-manybugs path/to/manybugs

The bugzoo source list command can be used to provide a list of registered sources:

$ bugzoo source list

Source    Type    URL                                         Location                                                        Version
--------  ------  ------------------------------------------  --------------------------------------------------------------  ---------
robust    Local   -                                           /home/chris/bugs/robust                                         -
genprog   Remote  https://github.com/squaresLab/genprog-code  /home/chris/.bugzoo/sources/github_com_squaresLab_genprog-code  b4de21d7
manybugs  Remote  https://github.com/squaresLab/ManyBugs      /home/chris/.bugzoo/sources/github_com_squaresLab_ManyBugs      ad83bd9a

And bugzoo bug list and bugzoo tool list can be used to produce a list of all bugs and tools that are provided by your registered sources:

$ bugzoo bug list

...

To interact with a particular bug or tool, you'll need to install it on your machine. There are two ways to do this: (1) you can build the Docker image for the bug or tool locally (via bugzoo bug build and bugzoo tool build), or alternatively, you can download a prebuilt image (via bugzoo bug download or bugzoo tool download).

$ bugzoo bug build manybugs:libtiff:2005-12-14-6746b87-0d3d51d
