Dataset of the Paper: Demystifying Code Snippets in Code Reviews: A Study of the OpenStack and Qt Communities and A Practitioner Survey

This dataset, which is composed of two parts: the code review data collected from OpenStack and Qt, and the survey data collected from industrial developers, was used to conduct an empirical study on code snippets in code reviews. A brief description of each part of the dataset is provided below: 1. Dataset (OpenStack+Qt).xlsx contains 127,182 review comments mined from four popular projects of the OpenStack community (Nova and Neutron) and the Qt community (Qt Base and Qt Creator) from 2020 to 2021. Among the review comments, 3,197 review comments contain code snippets. In the Excel file, for the rows of review comments with code snippets, we marked the code snippets in red color as an indicator. 2. Dataset (Survey).xlsx contains 63 valid responses to our survey questionnaire from industrial developers of OpenStack, Qt, and LinkedIn.
