SoHist, a solution for retro perspective code analysis

What is it about?

SoHist, by the University of Innsbruck, is one of the tools developed within SmartDelta that facilitates the accurate analysis and determination of quality implications of each change and increment to a system. It emerged through the collaboration between c.c.com Moser GmbH, Software AG Research and the University of Innsbruck. Code analysis tools are often used to facilitate the automated assessment of various forms of technical debt, such as reliability (bugs), security, or maintainability (code smells). In their preliminary survey, the project partners identified SonarQube as the industry’s most important code analysis tool, with over 200,000 companies worldwide that fall back on it. Currently, SonarQube has some limitations when it comes to applying it in incremental industrial software systems. These limitations include: - lacking comparability of code evolution if SonarQube versions change over time, - cumbersome processes are needed to retrieve historical quality analysis, and - visualisations that limit the interpretation of code quality aspects and do not consider individual project requirements. SoHist addresses these issues by building on SonarQube’s strengths and providing additional features to assess and prioritise technical debt. The containerised application enables companies to connect to their GIT repository and execute retro-perspective code analysis with several filtering options (committers, time range, or branch). After the analysis, a dashboard helps to interpret the technical debt in more detail. For instance, users can display multiple code quality metrics simultaneously and compare those against each other. Additionally, users can adjust the weighting of various code quality aspects based on the unique contexts and goals of the project. Using this input, the Weighted Code Evolution Significance is calculated, which offers a means of identifying the changes that have had the most significant impact based on their respective weights. The SoHist prototype has already demonstrated its advantages to two SmartDelta partners. For instance, c.c.com Moser GmbH is leveraging the tool to gather energy-related code metrics for sensor firmware changes. Another example is Software AG Research that by using SoHist can monitor code quality trends throughout a project's lifespan. This allows them to enhance project advancement and take corrective actions if necessary.
