Employing the fast DDP type inferencer, it is effective on dynamically typed code bases an order of magnitude larger than the code bases supported by previous browsers. Chuck supports the full Smalltalk language, and is now shipped as a standard component of the Squeak open-source Smalltalk system, where it routinely works with code bases exceeding 300,000 lines of code. Chuck's implementation is tuned for interactive use, and is transparently integrated with the Squeak system's existing code-browsing tools. Thus, it provides semantic navigation of a live code base that is still being edited without requiring long pauses for reanalysis due to edits of the code.","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117351921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whitehead","doi":"10.1109/WCRE.2005.33","DOIUrl":"https://doi.org/10.1109/WCRE.2005.33","url":null,"abstract":"It is a common understanding that identifying the same entity such as module, file, and function between revisions is important for software evolution related analysis. Most software evolution researchers use entity names, such as file names and function names, as entity identifiers based on the assumption that each entity is uniquely identifiable by its name. Unfortunately names change over time. In this paper, we propose an automated algorithm that identifies entity mapping at the function level across revisions even when an entity's name changes in the new revision. This algorithm is based on computing function similarities. We introduce eight similarity factors to determine if a function is renamed from a function. To find out which similarity factors are dominant, a significance analysis is performed on each factor. To validate our algorithm and for factor significance analysis, ten human judges manually identified renamed entities across revisions for two open source projects: Subversion and Apache2. Using the manually identified result set we trained weights for each similarity factor and measured the accuracy of our algorithm. We computed the accuracies among human judges. We found our algorithm's accuracy is better than the average accuracy among human judges. We also show that trained weights for similarity factors from one period in one project are reusable for other periods and/or other projects. Finally we combined all possible factor combinations and computed the accuracy of each combination. We found that adding more factors does not necessarily improve the accuracy of origin detection.","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114886365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing systems are usually reengineered because it is cheaper to reengineer them than to redevelop or to replace them.

This paper examines techniques for automatic deobfuscation of obfuscated programs, as a step towards reverse engineering such programs. Our results indicate that much of the effects of code obfuscation, designed to increase the difficulty of static analyses, can be defeated using simple combinations of straightforward static and dynamic analyses. Our results have applications to both software engineering and software security. In the context of software engineering, we show how dynamic analyses can be used to enhance reverse engineering, even for code that has been designed to be difficult to reverse engineer. For software security, our results serve as an attack model for code obfuscators, and can help with the development of obfuscation techniques that are more resilient to straightforward reverse engineering.","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124160514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Algorithms for syntax-preserving slicing are well established, but amorphous slicing is harder because it requires arbitrary transformation; finding good general purpose amorphous slicing algorithms therefore remains as hard as general program transformation. In this paper we show how amorphous slices can be computed using search techniques. The paper presents results from a set of experiments designed to explore the application of genetic algorithms, hill climbing, random search and systematic search to a set of six subject programs. As a benchmark, the results are compared to those from an existing analytical algorithm for amorphous slicing, which was written specifically to perform well with the sorts of program under consideration. The results, while tentative at this stage, do give grounds for optimism. The search techniques proved able to reduce the size of the programs under consideration in all cases, sometimes equaling the performance of the specifically-tailored analytic algorithm. In one case, the search techniques performed better, highlighting a fault in the existing algorithm","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123188005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While in recent years, there has been significant progress in the area of automatic detection of \"code smells\" on one hand, and code refactorings on the other hand, we claim that existing restructuring practices are seriously hampered by their symptomatic and informal (non-repeatable) nature. This paper makes a clear distinction between structural problems and structural symptoms (also known as code smells), and presents a novel, causal approach to restructuring object oriented systems. Our approach is based on two innovations: the encapsulation of correlations of symptoms and additional contextual information into higher-level design problems, and the univocal, explicit mapping of problems to unique refactoring solutions. Due to its explicit, repeatable nature, the approach shows high potential for increased levels of automation in the restructuring process, and consequently a decrease in maintenance costs.","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126570808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What the code is about can be found in the semantics of the source code: names of identifiers, comments etc. In this paper, we analyze how these terms are spread over the source artifacts using latent semantic indexing, an information retrieval technique. We use the assumption that parts of the system that use similar terms are related. We cluster artifacts that use similar terms, and we reveal the most relevant terms for the computed clusters. Our approach works at the level of the source code which makes it language independent. Nevertheless, we correlated the semantics with structural information and we applied it at different levels of abstraction (e.g. classes, methods). We applied our approach on three large case studies and we report the results we obtained.","PeriodicalId":119724,"journal":{"name":"12th Working Conference on Reverse Engineering (WCRE'05)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131927935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
