• Authors: Fabrizio Montesi, Marco Peressotti, Valentino Picotti, Olaf Zimmermann,
• Abstract summary: We introduce a conceptual framework for the implementation of APIs. Our framework elicits that there are important trade-offs and choices, which significantly affect the efficiency, maintainability, and isolation properties of the resulting architecture. Our work also elicits, for the first time, how certain programming language features can reduce friction in applying API and open up more architectural choices.

• Abstract: Enterprise applications are often built as service-oriented architectures, where the individual services are designed to perform specific functions and interact with each other by means of well-defined APIs (Application Programming Interfaces). The architecture of an enterprise application evolves over time, in order to adapt to changing business requirements. This evolution might require changes to the APIs offered by services, which can be achieved through appropriate API refactorings. Previous studies on API refactoring focused on the effects on API definitions, with general considerations on related forces and smells. So far, instead, the development strategy for realising these refactorings has received little attention. This paper addresses exactly this aspect. We introduce a conceptual framework for the implementation of API refactorings. Our framework elicits that there are important trade-offs and choices, which significantly affect the efficiency, maintainability, and isolation properties of the resulting architecture. We validate our framework by implementing several refactorings that introduce established API patterns with different choices, which illustrates the guiding principles offered by our framework. Our work also elicits, for the first time, how certain programming language features can reduce friction in applying API refactoring and open up more architectural choices.

  We introduce AsCAN -- a hybrid architecture, combining both convolutional and transformer blocks. AsCAN supports a variety of tasks: recognition, segmentation, class-conditional image generation. We then scale the same architecture to solve a large-scale text-to-image task and show state-of-the-art performance.

  We propose a novel framework for creating APIs for legacy mainframe applications. Our approach involves identifying APIs by compiling artifacts such as transactions, screens, control flow blocks, inter-microservice calls, business rules, and data accesses. We use static analyses like liveness and reaching definitions to traverse the code and automatically compute API signatures.

  API call generation is the cornerstone of large language models' tool-using ability. Existing supervised and in-context learning approaches suffer from high training costs, poor data efficiency, and generated API calls that can be unfaithful to the API documentation and the user's request. We propose an output-side optimization approach called FANTASE to address these limitations.

  We present a novel conceptual framework designed to assist library maintainers in understanding the interactions allowed by their APIs. These customizable models enable library maintainers to improve their design ahead of release, reducing friction during evolution. We implement these models for Java libraries in a new tool UCov and demonstrate its capabilities on three libraries exhibiting diverse styles of interaction.

  Refactoring is the art of improving the design of a system without altering its external behavior. This study categorizes commits into 3 categories, namely, Internal QA, External QA, and Code Smell Resolution, along with the traditional BugFix and Functional categories. To better understand our classification results, we analyzed commit messages to extract patterns that developers regularly use to describe their smells.
