CAREER: Cooperative Program Analysis: Bridging the Gap Between User and Tool Reasoning

虽然并不完美，但今天的自动化分析工具所能分析出的程序的深度和广度确实令人瞩目。 然而，尽管软件缺陷的流行和成本，尽管这样的自动化工具可以提供丰富的信息，程序分析器在很大程度上被今天的软件工程师忽视。 这种情况不是由于软件工程师缺乏兴趣或分析专家在部署方面缺乏努力，而是由于工具及其用户对程序的推理方式存在差距，这导致例如难以提供用户可理解的分析结果。 本研究致力于缩小用户与工具之间的推理差距，研究的重点是一种有效的用户驱动的分析过程细化方法。 将创建用于生成程序分析结果的解释的新技术。 将开发新的方法来权衡编译时验证的详尽性和运行时检查的简单性。 连同以前的工作，以用户为中心的分析规范，这个项目奠定了基础，为明天的工具，用户和工具合作，有效地理由有关的程序。 重要的潜在影响包括：改变软件工程师看待程序分析的方式--用透明的推理助手取代魔术盒，由于这种观点的改变而提高软件质量，以及让学生以动手的方式进行算法思考的工具。

While not perfect, the depth and breadth of what today's automated analysis tools can figure out about a program is truly remarkable. Yet, despite the prevalence and cost of software defects and despite the wealth of information such automated tools could provide, program analyzers are largely ignored by today's software engineers. This situation is not due to a lack of interest from software engineers or a lack of effort in deployment from analysis experts but rather a gap in the way a tool and its user reasons about the program, which results in, for example, a difficulty in providing analysis results understandable to the user. This research confronts closing this user-tool reasoning gap.The focus of the work is an effective approach to user-driven refinement of the analysis process. Novel techniques for generating explanations of program analysis results will be created. New approaches for trading off the exhaustiveness of compile-time verification and the simplicity of run-time checking will be developed. Together with prior work on user-centric analysis specifications, this project lays the foundation for tomorrow's tools where users and tools cooperate to reason effectively about programs. Significant potential impacts include the following: a change in the way software engineers view program analysis--replacing a magic box with a transparent reasoning assistant, improved software quality as a result of this change in view, and tools that engage students in algorithmic thinking in a hands-on manner.
