| Abstract | Reproducing non-deterministic bugs is challenging. Recording program execution in production environments and reproducing bugs is an effective way to re-enable cyclic debugging. Unfortunately, most current record-replay approaches introduce large perturbations to either environments and/or execution flow, in addition to performance penalty and high storage overhead, which make them impracticable to be deployed in production environments. This paper presents Snitchaser — a fully user-space record-replay tool which can faithfully reproduce bugs by replaying system calls which are recorded with negligible perturbation and recording overhead. This is achieved by 1) a novel, lightweight system call interception mechanism without patching the binary instructions to reduce the perturbation to execution flow; 2) system call latch to save signal semantic; 3) periodic checkpointing to reduce the storage overhead. Snitchaser focuses on bugs caused by asynchronous events on heavily loaded, high throughput servers. Experimental results show that Snitchaser is capable of reproducing non-deterministic bugs efficiently at nearly no performance penalty. We also present two case studies on dealing with existing bugs in Lighttpd — a popular software used in many large scale systems. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
