Bug fix is an important and challenging task in software development and maintenance. Bug fix is also a dangerous change, because it might induce new bugs. It is difficult to decide whether a bug fix is safe in practice. In this paper, we conducted an empirical study on bug inducing analysis to discover the types and features of fault prone bug fixes. We use a classical algorithm to track the l...

In automatic software bug localization, source code analysis is usually used to localize the buggy code without manual intervention. However, due to considering irrelevant source code, localization accuracy may get biased. In this paper, a Method level Bug localization using Minimized search space (MBuM) is proposed for improving the accuracy, which considers only the liable source code for gen...

There is a gap between the information available at the time of a software failure and the information actually shipped to developers in the corresponding bug report. As a result, identifying the cause of the bug based on this bug report is often difficult. To close this gap, we propose bug fingerprints—an augmentation of classic automated bug reports with runtime information about how the repo...

Most of the software companies need to deal with vast number of software bugs day to day. This paper can be viewed as an application of instance selection and feature selection in bug repositories. The aim is to address the problem of data reduction for bug triage, and to reduce the scale and improve the quality of bug data. This can be achieved by combining instance selection with feature sele...

Some bugs, among the millions that exist, are similar to each other. When fixing a bug, a programmer tends to search for similar bugs that have been reported and resolved in the past. A fix for a similar bug can help him understand his bug, or even directly fix his bug. Studying bugs with similar symptoms, programmers may determine how to detect or resolve them. Existing work has focused on ana...

We present and categorize a taxonomy of concurrent bug patterns. We then use the taxonomy to create new timing heuristics for ConTest. Initial industrial experience indicates that these heuristics improve the bug finding ability of ConTest. We also show how concurrent bug patterns can be derived from concurrent design patterns. Further research is required to complete the concurrent bug taxonom...

Not all bugs in software would be experienced and reported by end users right away: Some bugs manifest themselves quickly and may be reported by users a few days after they get into the code base; others manifest many months or even years later, and may only be experienced and reported by a small number of users. We refer to the period of time between the time when a bug is introduced into code...

demographic analyses of dubas bug, ommatissus lybicus de bergevin, (hemiptera: tropiduchidae), reared on five date palm varieties (zahdi, mazafati, piarom, khasi, and shahani) were constructed under laboratory conditions at 27±1ºc, 70±5% rh, and a 14:10 hours (l: d) photoperiod. data were analyzed based on the age-stage, two-sex life table theory to take the variable developmental rate among in...

Bug prediction is a technique used to estimate the most bug-prone entities in software systems. Bug prediction approaches vary in many design options, such as dependent variables, independent variables, and machine learning models. Choosing the right combination of design options to build an effective bug predictor is hard. Previous studies do not consider this complexity and draw conclusions b...
