This package contains the virtual machine used for the TAP 2020 artifact evaluation. The TAP 2020 virtual machine was created with VirtualBox 6.0.16 and consists of an installation of Ubuntu 19.04 with Linux 5.0.0-38 and the following notable packages. OCaml 4.09.0 OpenJDK 1.8.0_232 OpenJDK 13 (2019-09-17) Mono 6.8.0.105 Ruby 2.5.5p157 Python 2.7.16 and Python 3.7.3 bash 5.0.3 cmake 3.13.4 clang 8.0.0.3 gcc 8.3.0 Racket 7.5 VIM 8.1 Emacs 26.1 Coq 8.9.1 with CoqIDE 8.9.1 benchexec 2.5 TexLive 2019 A 32bit libc VirtualBox guest additions 6.0.16 To switch between Java versions, you can use sudo update-alternatives --config java. The default Java version is Java 1.8. The VM has a user tap2020 with password tap2020. The root user has the same password. In order to save space, the VM does not have an active swap file. Please mention in your submission if you expect that a swap file is needed. You can activate swap for the running session using the following commands. sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile The artifact evaluation committee will be instructed not to download software or data from external sources. Any additional software required by your artifact must be included in the .zip file and the artifact must provide instructions for the installation. To include an Ubuntu package in your artifact submission, you can create a .deb file with all the necessary dependencies from inside the VM. Reviewers can then install them by using sudo dpkg -i <.deb file>. You can create the necessary .deb files for example as follows. If you have only one package without dependencies, you can use apt-get download <packagename> If you have only one package without dependencies but with local modifications, e.g., particular configuration files, you can use the dpkg-repack utility If you have a package with multiple dependencies, you can use wget together with apt to download them all and put them into a folder: wget $(apt-get install --reinstall --print-uris -qq <packagename> | cut -d"'" -f2)
