Software repair is the academic field and methodological approach concerned with the automated or semi-automated modification of existing software systems to address defects, vulnerabilities, or functional requirements. This domain investigates techniques for identifying issues, locating their source within the codebase, and generating or applying corrective or enhancing code modifications. Key characteristics include the development of automated program analysis and transformation tools, aiming for correctness, efficiency, and scalability. Its significance lies in enabling essential software maintenance, enhancing system security and reliability, extending software lifespan, and supporting the ability to adapt software to changing environments or user needs, aligning with the necessity for software to evolve in response to real-world demands and maintenance imperatives.
