| Abstract | We present an effective dynamic analysis for finding a broad class of deadlocks, including the well-studied lock-only deadlocks as well as the less-studied, but no less widespread or insidious, deadlocks involving condition variables. Our analysis consists of two stages. In the first stage, our analysis observes a multi-threaded program execution and generates a simple multi-threaded program, called a trace program, that only records operations observed during the execution that are deemed relevant to finding deadlocks. Such operations include lock acquire and release, wait and notify, thread start and join, and change of values of user-identified synchronization predicates associated with condition variables. In the second stage, our analysis uses an off-the-shelf model checker to explore all possible thread interleavings of the trace program and check if any of them deadlocks. A key advantage of our technique is that it discards most of the program logic which usually causes state-space explosion in model checking, and retains only the relevant synchronization logic in the trace program, which is sufficient for finding deadlocks. We have implemented our analysis for Java, and have applied it to twelve real-world multi-threaded Java programs. Our analysis is effective in practice, finding thirteen previously known as well as four new deadlocks. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
