| Abstract | Correct error handling is essential for building reliable and secure systems. Unfortunately, low-level languages like C often do not support any error handling primitives and leave it up to the developers to create their own mechanisms for error propagation and handling. However, in practice, the developers often make mistakes while writing the repetitive and tedious error handling code and inadvertently introduce bugs. Such error handling bugs often have severe consequences undermining the security and reliability of the affected systems. Fixing these bugs is also tiringâ they are repetitive and cumbersome to implement. Therefore, it is crucial to develop tool supports for automatically detecting and fixing error handling bugs. To understand the nature of error handling bugs that occur in widely used C programs, we conduct a comprehensive study of real world error handling bugs and their fixes. Leveraging the knowledge, we then design, implement, and evaluate ErrDoc, a tool that not only detects and characterizes different types of error handling bugs but also automatically fixes them. Our evaluation on five open-source projects shows that ErrDoc can detect error handling bugs with 100% to 84% precision and around 95% recall, and categorize them with 83% to 96% precision and above 90% recall. Thus, ErrDoc improves precision up to 5 percentage points, and recall up to 44 percentage points w.r.t. the state-of-the-art. We also demonstrate that ErrDoc can fix the bugs with high accuracy. . |

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.
