Runtime verification (RV) can help find bugs early, before the software is deployed. RV monitors program executions against formal behavioral specifications and generates violations if those executions do not satisfy the specifications. Prior RV research found hundreds of bugs in scores of open-source projects. But that prior research used tooling that only targets the Java programming language and checks specifications written in a domain-specific language that is hard for new RV users to learn. This project’s impact is to make RV more widely used for bug finding among developers by creating RV tool support for other programming languages and simpler specification formats. The project’s novelty is that it targets commonly-used languages and formats to lower the language barriers to entry for developers who are new to RV, and makes it easier for them to write specifications. The investigators will train undergraduate students to participate in developing OpenMOP, create modules on OpenMOP in their software engineering classes, and evaluate OpenMOP usage when deploying it to find bugs during software development.This project proposes OpenMOP to address infrastructure gaps that today make it hard to use RV to find bugs. OpenMOP is an RV infrastructure that builds on and reuses parts of JavaMOP -- an RV tool for Java that has been in development since 2002. OpenMOP provides two new features. First, it enables developers to describe program events and properties in formats that they are already familiar with. For example, in one proposed format, developers can define the program events needed to specify program behavior at a small set of program locations, similar to adding breakpoints for debugging. Second, OpenMOP adopts a language-agnostic client-server architecture to enable the rapid creation of efficient RV tools for different programming languages.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

运行时验证 (RV) 可以帮助在部署软件之前尽早发现错误，RV 会根据正式的行为规范监控程序执行情况，如果这些执行不满足规范，则会产生违规行为。 RV 研究发现了数十个开源代码中的数百个错误。但之前的研究使用的工具仅针对 Java 编程语言，并检查用特定于领域的语言编写的规范，而这对新 RV 用户来说很难学习。该项目的影响是使开发人员更广泛地使用 RV 来查找错误。通过为其他人创建 RV 工具支持该项目的新颖之处在于它针对常用的语言和格式，以降低 RV 新手的入门语言障碍，并使他们更容易编写规范。研究人员将培训本科生参与 OpenMOP，在软件工程课程中创建 OpenMOP 模块，并在部署 OpenMOP 时评估 OpenMOP 的使用情况，以发现软件开发过程中的错误。该项目建议 OpenMOP 来解决基础设施的缺陷，这些缺陷如今使得开发变得难以使用房车寻找bug。 OpenMOP 是一个 RV 基础设施，它构建并重用了 JavaMOP（自 2002 年以来一直在开发的 Java RV 工具）的部分内容。OpenMOP 提供了两个新功能：首先，它使开发人员能够以其本身的格式描述程序事件和属性。例如，在一种建议的格式中，开发人员可以定义在一小部分程序位置指定程序行为所需的程序事件，类似于添加断点进行调试。 其次，OpenMOP 采用与语言无关的方式。客户端-服务器架构，能够为不同的编程语言快速创建高效的 RV 工具。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
