Abstract

Errors such as deadlock and race conditions are very common yet extremely difficult to debug in the communications design of client/server models based on remote procedure calls and multi-threading. This paper presents an effective approach to detecting these errors. It shows how to apply the specification and validation techniques used in protocol engineering to discover those errors in the early stages of a client/server software development. The work is based on the protocol specification and validation tool PROMELA/SPIN. PROMELA is extended to a new language called PROMELA-C/S for additional expressive power of specifying client/server communications. A PROMELA-C/S translator is built to convert PROMELA-C/S to PROMELA for validation using SPIN. The paper also reports the results of some specification and validation trials using PROMELA-C/S, its translator, and SPIN.<>
客户端/服务器模型中通信的规范和验证
在基于远程过程调用和多线程的客户机/服务器模型的通信设计中,死锁和竞争条件等错误非常常见,但极难调试。本文提出了一种检测这些误差的有效方法。它展示了如何应用协议工程中使用的规范和验证技术,在客户端/服务器软件开发的早期阶段发现这些错误。该工作基于协议规范和验证工具PROMELA/SPIN。PROMELA扩展为一种名为PROMELA- c /S的新语言,用于指定客户端/服务器通信的额外表达能力。构建了PROMELA- c /S转换器,将PROMELA- c /S转换为PROMELA,以便使用SPIN进行验证。本文还报告了使用PROMELA-C/S及其翻译器和SPIN. b>进行的一些规范和验证试验的结果
