On the Origins of Coccinelle

Authors: Julia Lawall

Published in: OASIcs, Volume 109, Eelco Visser Commemorative Symposium (EVCS 2023)

Abstract
Coccinelle is a program-transformation system for C code. It has been under development since 2005 and has been extensively used on the Linux kernel. The design of Coccinelle was inspired in part by the author’s previous experience in using Stratego/XT, developed by Eelco Visser. This paper reflects on some of Coccinelle’s design choices and their relation to Eelco Visser’s work.

Semantic Patches for Java Program Transformation (Artifact)

Authors: Hong Jin Kang, Ferdian Thung, Julia Lawall, Gilles Muller, Lingxiao Jiang, and David Lo

Published in: DARTS, Volume 5, Issue 2, Special Issue of the 33rd European Conference on Object-Oriented Programming (ECOOP 2019)

Abstract
The program transformation tool Coccinelle is designed for making changes that is required in many locations within a software project. It has been shown to be useful for C code and has been been adopted for use in the Linux kernel by many developers. Over 6000 commits mentioning the use of Coccinelle have been made in the Linux kernel. Our artifact, Coccinelle4J, is an extension to Coccinelle in order for it to apply program transformations to Java source code. This artifact accompanies our experience report "Semantic Patches for Java Program Transformation", in which we show a case study of applying code transformations to upgrade usage of deprecated Android API methods to replacement API methods.

Semantic Patches for Java Program Transformation (Experience Report)

Authors: Hong Jin Kang, Ferdian Thung, Julia Lawall, Gilles Muller, Lingxiao Jiang, and David Lo

Published in: LIPIcs, Volume 134, 33rd European Conference on Object-Oriented Programming (ECOOP 2019)

Abstract
Developing software often requires code changes that are widespread and applied to multiple locations. There are tools for Java that allow developers to specify patterns for program matching and source-to-source transformation. However, to our knowledge, none allows for transforming code based on its control-flow context. We prototype Coccinelle4J, an extension to Coccinelle, which is a program transformation tool designed for widespread changes in C code, in order to work on Java source code. We adapt Coccinelle to be able to apply scripts written in the Semantic Patch Language (SmPL), a language provided by Coccinelle, to Java source files. As a case study, we demonstrate the utility of Coccinelle4J with the task of API migration. We show 6 semantic patches to migrate from deprecated Android API methods on several open source Android projects. We describe how SmPL can be used to express several API migrations and justify several of our design decisions.

Towards Class-Based Dynamic Voltage Scaling for Multimedia Applications

Authors: Richard Urunuela, Gilles Muller, and Julia Lawall

Published in: Dagstuhl Seminar Proceedings, Volume 7041, Power-aware Computing Systems (2007)

Abstract
Video display has significant, but highly variable, CPU requirements. As such, it is an attractive target for power management via dynamic voltage scaling. In previous work, we have proposed a dynamic voltage scaling algorithm directed to the context of video kiosks, in which a minimal frequency for each frame can be determined experimentally based on observations taken during the first few iterations of the video. In this paper, we review that work, and begin to consider how such an approach can be adapted to the more common case where a video is only played once, on hardware that is not known in advance.
