| Abstract | Some bugs, among the millions that exist, are similar to each other. One bug-fixing tactic is to search for similar bugs that have been reported and resolved in the past. A fix for a similar bug can help a developer understand a bug, or even directly fix it. Studying bugs with similar symptoms, programmers may determine how to detect or resolve them. To speed debugging, we advocate the systematic capture and reuse of debugging knowledge, much of which is currently wasted. The core challenge here is how to search for similar bugs. To tackle this problem, we exploit semantic bug information in the form of execution traces, which precisely capture bug semantics. This paper introduces novel tool and language support for semantically querying and analyzing bugs. We describe OSCILLOSCOPE, an Eclipse plugin, that uses a bug trace to exhaustively search its database for similar bugs and return their bug reports. OSCILLOSCOPE displays the traces of the bugs it returns against the trace of the target bug, so a developer can visually examine the quality of the matches. OSCILLOSCOPE rests on our bug query language (BQL), a flexible query language over traces. To realize OSCILLOSCOPE, we developed an open infrastructure that consists of a trace collection engine, BQL, a Hadoop-based query engine for BQL, a trace-indexed bug database, as well as a web-based frontend. OSCILLOSCOPE records and uploads bug traces to its infrastructure; it does so automatically when a JUnit test fails. We evaluated OSCILLOSCOPE on bugs collected from popular open-source projects. We show that OSCILLOSCOPE accurately and efficiently finds similar bugs, some of which could have been immediately used to fix open bugs. |

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.
