A Study on Concurrency Bugs in an Open Source Software

Abstract
Concurrent programming puts demands on software debugging and
testing, as concurrent software may exhibit problems not present in sequential
software, e.g., deadlocks and race conditions. In aiming to increase efficiency
and effectiveness of debugging and bug-fixing for concurrent software,
a deep understanding of concurrency bugs, their frequency and fixing-times
would be helpful. Similarly, to design effective tools and techniques for testing
and debugging concurrent software understanding the differences between
non-concurrency and concurrency bugs in real-word software would be useful.
This paper presents an empirical study focusing on understanding the differences
and similarities between concurrency bugs and other bugs, as well as the
differences among various concurrency bug types in terms of their severity and
their fixing time. Our basis is a comprehensive analysis of bug reports covering
several generations of an open source software system. The analysis involves
a total of 4872 bug reports from the last decade, including 221 reports related
to concurrency bugs. We found that concurrency bugs are different from other
bugs in terms of their fixing time and their severity. Our findings shed light on
concurrency bugs and could thereby influence future design and development of
concurrent software, their debugging and testing, as well as related tools.
