CppPerf: Automatic C++ Performance-Optimization Commits Mining Pipeline

CppPerf is an automatic pipeline to collect performance-optimization commits from GitHub. The pipeline mines repositories from GitHub, identifies candidate performance-optimizing commits from the collected repositories, builds and executes the commits in Docker environments, performs statistical performance evaluation on the execution results, and stores the commits in Docker images and results in json files. The repository also contains a dataset of 347 execution time improvement patches collected from 42 projects.
