With the advent of fast software evolution and multistage releases, temporal code analysis is becoming useful for various purposes, such as bug cause identification, bug prediction or code evolution analysis. Temporal code analyses can consist in ...

One of the important purposes of code review is to find potential defects caused by other developers' code changes. When reviewing bug fixes, it is important to check the program behavior is properly changed to remove the bug. On the other hand, it is ...

The way humans and algorithms look at and understand differences between versions and variants of the same text may be very different. While correctness and overall byte length are fundamental aspects of good outputs of diff algorithms, they do not ...

Effectively computing the difference between two version of a source file has become an indispensable part of software development. The de facto standard tool used by most version control systems is the UNIX diff utility, that compares two files on a ...

diffi (diff improved) is a comparison tool whose primary goal is to describe the differences between the content of two documents regardless of their formats.

diffi examines the stacks of abstraction levels of the two documents to be compared, finds ...

To attract more users on different platforms, many projects release their versions in multiple programming languages (e.g., Java and C#). They typically have many code snippets that implement similar functionalities, i.e., cross-language clones. ...

Collaborating on a piece of code is notoriously difficult when the number of people involved goes above 1. In particular, every computer programmer dreads the "merge conflict", a brutal, unforgiving experience, where they must reconcile their changes ...

Documentary production often involves a revising process in which documents need to be proofread. This important task faces new challenges when dealing with digital documents. Indeed, three features of digital writing are problematic: (1) documents ...

During the software life cycle, artifacts change in response to both corrective and evolutive demands. These changes usually entail source-code refactorings. However, conventional diff algorithms do not precisely capture such type of changes due to ...

Detecting and understanding changes between document revisions is an important task. The acquired knowledge can be used to classify the nature of a new document revision or to support a human editor in the review process. While purely textual change ...

Dynamic system update problem, DSU, is about replacing a running application with another version without interrupting its work or disrupting its users. Some solutions for DSU support only certain kinds of updates, which makes it dangerous to apply them ...

Applications which deal with editing of structured data over multiple iterations, such as structure editors, exercise assistants, or applications which support incremental computation, need to represent transformations between different versions of ...

Tracking source code lines between two different versions of a file is a fundamental step for solving a number of important problems in software maintenance such as locating bug introducing changes, tracking code fragments or defects across versions, ...

There are currently no shared formalization of the output of diff algorithms, the so called deltas. From a theoretical point of view, without such a formalization it is difficult to compare the output of different algorithms. In more practical terms, ...

With the increasing use of Web 2.0 to create, disseminate, and consume large volumes of data, more and more information is published and becomes available for potential data consumers, that is, applications/services, individual users and communities, ...

The analysis of changes between OWL ontologies (in the form of a diff ) is an important service for ontology engineering. A purely syntactic analysis of changes is insufficient to distinguish between changes that have logical impact and those that do ...

Firmware update over a network connection is an essential but expensive feature for many embedded systems due to not only the relatively high power consumption and limited bandwidth, but also page-granular erasure before rewriting to flash memory. This ...

Automatic and advanced merging algorithms help programmers to merge their modifications in main development repositories. However, there is little support to help release masters (integrators) to take decisions about the integration of published merged ...

All the support tools that developers are used to must be in place, if the use of model-centric development in companies has to take off. Industry deals with big models and many people working on the same model. Collaboration in a team inevitably leads ...

Previous work on tracking source locations has focused on tracking lines through multiple revisions of software.In this paper, we explore a new technique for tracking statements, rather than lines, across multiple revisions of Java source code.We show ...
