For instance, to repair several instances of a bug or to update all clients of a library to a newer version. Manually performing such changes is laborious and error-prone. Program transformation tools enable automating changes, but specifying changes as a program transformation requires significant expertise. Code templates are often touted as a remedy, yet have never been endorsed wholeheartedly. Their use is mostly limited to expressing the syntactic characteristics of the intended change subjects. Less familiar means have to be resorted to for expressing their structural, control flow, and data flow characteristics. In this tool paper, we introduce a decidedly template-driven program transformation tool called Ekeko/X. Its specifications feature templates for specifying all of the aforementioned characteristics of its subjects. To this end, developers can associate different directives with individual components of a template. Each matching directive imposes particular constraints on the matches for the component it is associated with. Rewriting directives, on the other hand, determine how each match should be changed. We develop Ekeko/X from the ground up, starting from its applicative logic meta-programming foundation. We highlight the key choices in this implementation and demonstrate its use through two example program transformations.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134530490","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}

Various test optimization methods, e.g. Test selection and prioritization, rely on code coverage information, but other related fields benefit from it as well, such as fault localization. These methods require access to the fine details of coverage information and efficient ways of processing this data. The purpose of the (free) SoDA library and toolset is to provide an efficient set of data structures and algorithms which can be used to prepare, store and analyze in various ways data related to code coverage. The focus of SoDA is not on the calculation of coverage data (such as instrumentation and test execution) but on the analysis and manipulation of test suites based on such information. An important design goal of the library was to be usable on industrial-size programs and test suites. Furthermore, there is no limitation on programming language, analysis granularity and coverage criteria. In this paper, we demonstrate the purpose and benefits of the library, the associated toolset, which also includes a graphical user interface, as well as possible usage scenarios. SoDA also includes a repository of prepared programs, which are from small to large sizes and can be used for experimentation and as a benchmark for code coverage related research.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128425448","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}

In fact, in a recent study of 23K+ Java projects it has been found that only 10% of the messages are descriptive and over 66% of those messages contained fewer words as compared to a typical English sentence (i.e., 15-20 words). However, accurate and complete commit messages summarizing software changes are important to support a number of development and maintenance tasks. In this paper we present an approach, coined as Change Scribe, which is designed to generate commit messages automatically from change sets. Change Scribe generates natural language commit messages by taking into account commit stereotype, the type of changes (e.g., files rename, changes done only to property files), as well as the impact set of the underlying changes. We evaluated Change Scribe in a survey involving 23 developers in which the participants analyzed automatically generated commit messages from real changes and compared them with commit messages written by the original developers of six open source systems. The results demonstrate that automatically generated messages by Change Scribe are preferred in about 62% of the cases for large commits, and about 54% for small commits.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"485 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123406245","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}

Old 1st generation tools, based on screen coordinates, produce quite fragile test suites, tightly coupled with the specific screen resolution, window position and size experienced during test case recording. These tools have been replaced by a 2nd generation of tools, which offer easy selection and interaction with the web elements, based on DOM-oriented commands. Recently, a new 3rd generation of tools came up based on visual image recognition, bringing the promise of wider applicability and simplicity. A tester might ask if the migration towards such new technology is worthwhile, since the manual effort to rewrite a test suite might be overwhelming. In this paper, we propose PESTO, a tool facing the problem of the automated migration of 2nd generation test suites to the 3rd generation. PESTO determines automatically the screen position of each web element located on the DOM by a 2nd generation test case. It then calculates a screenshot image centred around the web element so as to ensure unique visual matching. Then, the entire source code of the DOM-based test suite is transformed into a visual test suite, based on such automatically extracted images and using specific visual commands.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128838363","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}

Co-change has been identified as a good predictor of the entities that are likely to be affected by a change, which ones might be missing modifications, and which ones might change in the future. However, existing co-change analysis provides no insight on why methods consistently co-change. Being able to identify the rationale that explains co-changes could allow to document and enforce design knowledge. This paper proposes an automatic approach to derive the reason behind a co-change. We define the reason of a (set) of co-changes as a set of properties common to the elements that co-change. We consider two kinds of properties: structural properties which indicate explicit dependencies, and semantic properties which reveal implicit dependencies. Then we attempt to identify the reasons behind single commits, as well as the reasons behind co-changes that repeatedly affect the same set of methods. These sets of methods are identified by clustering methods that tend to be modified in the same commit-transactions. We perform our analysis over the history of two open-source systems, analyzing nearly 19.000 methods and over 3700 commits. We show that it is possible to automatically extract explanations for co-changes, that the quality of such explanations improves when structural and semantic properties are taken into account, and when the methods analyzed co-change recurrently.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134257438","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 a number of studies identify some positive aspects of code clones, there is strong empirical evidence of some negative impacts of clones too. Focusing on the issues related to clones researchers suggest to manage code clones through detection, refactoring, and tracking. However, all clones in a software system are not suitable for refactoring or tracking. Thus, it is important to identify which clones we should consider for refactoring and which clones should be considered for tracking. In this research work we apply the concept of evolutionary coupling to identify clones that are important for refactoring or tracking. By mining software evolution history, we determine and analyze constrained association rules of clone fragments that evolved following a particular change pattern called Similarity Preserving Change Pattern and are important from the perspective of refactoring and tracking. According to our investigation with rigorous manual analysis on thousands of revisions of six diverse subject systems covering two programming languages, overall 13.20% of all clones in a software system are important candidates for refactoring, and overall 10.27% of all clones are important candidates for tracking. Our implemented system can automatically identify these important candidates and thus, can help us in better maintenance of code clones in terms of refactoring and tracking.","PeriodicalId":407060,"journal":{"name":"2014 IEEE 14th International Working Conference on Source Code Analysis and Manipulation","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126832175","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}
