It is crucial for distributed systems to achieve high availability. Unfortunately, this is challenging given the common component failures (i.e., faults). Developers often cannot anticipate all the timing conditions and system states under which a fault might occur, and introduce time-of-fault (TOF) bugs that only manifest when a node crashes or a message drops at a special moment. Although challenging, detecting TOF bugs is fundamental to developing highly available distributed systems. Unlike previous work that relies on fault injection to expose TOF bugs, this paper carefully models TOF bugs as a new type of concurrency bugs, and develops FCatch to automatically predict TOF bugs by observing correct execution. Evaluation on representative cloud systems shows that FCatch is effective, accurately finding severe TOF bugs.
期刊介绍：
The ACM Special Interest Group on Programming Languages explores programming language concepts and tools, focusing on design, implementation, practice, and theory. Its members are programming language developers, educators, implementers, researchers, theoreticians, and users. SIGPLAN sponsors several major annual conferences, including the Symposium on Principles of Programming Languages (POPL), the Symposium on Principles and Practice of Parallel Programming (PPoPP), the Conference on Programming Language Design and Implementation (PLDI), the International Conference on Functional Programming (ICFP), the International Conference on Object-Oriented Programming, Systems, Languages, and Applications (OOPSLA), as well as more than a dozen other events of either smaller size or in-cooperation with other SIGs. The monthly "ACM SIGPLAN Notices" publishes proceedings of selected sponsored events and an annual report on SIGPLAN activities. Members receive discounts on conference registrations and free access to ACM SIGPLAN publications in the ACM Digital Library. SIGPLAN recognizes significant research and service contributions of individuals with a variety of awards, supports current members through the Professional Activities Committee, and encourages future programming language enthusiasts with frequent Programming Languages Mentoring Workshops (PLMW).
