Many bugs, even those that are known and documented in bug reports, remain in mature software for a long time due to the lack of the development resources to fix them. We propose a general approach, R2Fix, to automatically generate bug-fixing patches from free-form bug reports. R2Fix combines past fix patterns, machine learning techniques, and semantic patch generation techniques to fix bugs automatically...
Concurrency bugs in an operating system (OS) are detrimental as they can cause the OS to fail and affect all applications running on top of the OS. Detecting OS concurrency bugs is challenging due to the complexity of the OS synchronization, particularly with the presence of the OS specific interrupt context. Existing dynamic concurrency bug detection techniques are designed for user level applications...
Innovations from multiple directions have been proposed to improve software reliability. Unfortunately, many of the innovations are not fully exploited by programmers. To bridge the gap, this paper proposes a new approach to ldquolistenrdquo to thousands of programmers: studying their programming comments. Since comments express programmers' assumptions and intentions, comments can reveal programmers'...
