Patching is a common activity in software development. It is generally performed on a source
code base to address bugs or add new functionalities. In this context, given the recurrence of …

Every software system undergoes changes, for example, to add new features, fix bugs, or
refactor code. The importance of understanding software changes has been widely …

Regression occurs when code changes introduce failures in previously passing test cases.
As software evolves, regressions may be introduced. Fixing regression errors manually is …

Background: Understanding maintenance activities performed in a source code repository
could help practitioners reduce uncertainty and improve cost-effectiveness by planning …

Cloud management systems provide abstractions and APIs for programmatically configuring
cloud infrastructures. Unfortunately, residual software bugs in these systems can potentially …

Automated program repair (APR) has extensively been developed by leveraging search-
based techniques, in which fix ingredients are explored and identified in different …

Deep learning (DL) has been a common thread across several recent techniques for
vulnerability detection. The rise of large, publicly available datasets of vulnerabilities has …

During the bug fixing process, developers usually need to analyze the source code to
induce the bug cause, which is useful for bug understanding and localization. The bug fixes …

We introduce Analytic Program Repair, a data-driven strategy for providing feedback for type-
errors via repairs for the erroneous program. Our strategy is based on insight that similar …

Automatic patch generation is often described as a search problem of patch candidate
space, and it has two major issues: one is search space size, and the other is navigation. An …
