APIfix: output-oriented program synthesis for combating breaking changes in libraries

Use of third-party libraries is extremely common in application software. The evolve to accommodate new features or mitigate security vulnerabilities, thereby breaking the Application Programming Interface(API) used by Such changes may discourage client code from using library versions keeping vulnerable and not up-to-date. We propose a novel output-oriented program synthesis algorithm automate API usage adaptations via transformation. Our aim only rely on few example human clients old version version, since this can lead over-fitting transformation rules. Instead, we also usages updated clients, which provide valuable context for synthesizing applying tool APIFix provides an automated mechanism transform - achieving adaptation fix effect changes. evaluation shows that rules inferred achieve 98.7% precision 91.5% recall. By comparing our approach state-of-the-art approaches, show significantly reduces while adaptations.
