Both social and technical changes affect an ecosystem's evolution and the research community has been investigating the impact of these modifications over the last few years. Existing studies mainly focus on temporary modifications, often ignoring the effect of permanent changes on the software ecosystem. We present an empirical study of the magnitude and effect of permanent modifications in both the social and technical parts of a software ecosystem. More precisely, we measure permanent changes with regard to the ecosystem's projects, contributors and source code files and present our findings concerning the effect of these modifications. We study the Ruby ecosystem in GitHub over a nine-year period by carrying out a socio-technical analysis of the co-evolution of a large number of base projects and their forks. This analysis involves both the source code developed for these projects as well as the developers having contributed to them. We discuss our findings with respect to the ecosystem evolution according to three different viewpoints: (1) the base projects, (2) the forks and (3) the entire ecosystem containing both the base projects and forks. Our findings show an increased growth in both the technical and social aspects of the Ruby ecosystem until early 2014, followed by an increased contributor and project abandonment rate. We show the effect of permanent modifications in the ecosystem evolution and provide preliminary evidence of contributors migrating to other ecosystems when leaving the Ruby ecosystem.","PeriodicalId":6541,"journal":{"name":"2017 IEEE 24th International Conference on Software Analysis, Evolution and Reengineering (SANER)","volume":"31 1","pages":"34-44"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80015324","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}

To migrate legacy software into a product line system, it is essential to identify the code segments that should be constructed as features from the source base. However, this could be an error-prone and complicated task, as it involves exploring a complex structure and extracting the relations between different components within a system. And normally, representing structural information of a program in a mathematical way should be a promising direction to investigate. We improve this situation by proposing a probability-based approach named StiCProb to capture source code fragments for feature concerned, which inherently provides a conditional probability to describe the closeness between two programming elements. In the case study, we conduct feature mining on several legacy systems, to compare our approach with other related approaches. As demonstrated in our experiment, our approach could support developers to locate features within legacy successfully with a better performance of 83% for precision and 41% for recall.","PeriodicalId":6541,"journal":{"name":"2017 IEEE 24th International Conference on Software Analysis, Evolution and Reengineering (SANER)","volume":"1 1","pages":"45-55"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78795551","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}

The lexical category for an identifier is determined from its declaration in the source code, syntactic meaning in the programming language, and static program analysis. Current techniques for assigning lexical categories to identifiers use natural-language part-of-speech taggers. However, these NLP approaches assign lexical tags based on how terms are used in English prose. The approach taken here differs in that it uses only source code to determine the lexical category. The approach assigns a lexical category to each identifier and stores this information along with each declaration. srcML is used as the infrastructure to implement the approach and so the lexical information is stored directly in the srcML markup as an additional XML element for each identifier. These lexical-category annotations can then be later used by tools that automatically generate such things as code summarization or documentation. The approach is applied to 50 open source projects and the soundness of the defined lexical categories evaluated. The evaluation shows that at every level of minimum support tested, categorization is consistent at least 79% of the time with an overall consistency (across all supports) of at least 88%. The categories reveal a correlation between how an identifier is named and how it is declared. This provides a syntax-oriented view (as opposed to English part-of-speech view) of developer intent of identifiers.","PeriodicalId":6541,"journal":{"name":"2017 IEEE 24th International Conference on Software Analysis, Evolution and Reengineering (SANER)","volume":"109 1","pages":"228-239"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79236047","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}

Like any system, libraries also evolve over time. As a consequence, clients are compelled to update and, thus, benefit from the available API improvements. However, some of these API changes may break contracts previously established, resulting in compilation errors and behavioral changes. In this paper, we study a set of questions regarding API breaking changes. Our goal is to measure the amount of breaking changes on real-world libraries and its impact on clients at a large-scale level. We assess (i) the frequency of breaking changes, (ii) the behavior of these changes over time, (iii) the impact on clients, and (iv) the characteristics of libraries with high frequency of breaking changes. Our large-scale analysis on 317 real-world Java libraries, 9K releases, and 260K client applications shows that (i) 14.78% of the API changes break compatibility with previous versions, (ii) the frequency of breaking changes increases over time, (iii) 2.54% of their clients are impacted, and (iv) systems with higher frequency of breaking changes are larger, more popular, and more active. Based on these results, we provide a set of lessons to better support library and client developers in their maintenance tasks.","PeriodicalId":6541,"journal":{"name":"2017 IEEE 24th International Conference on Software Analysis, Evolution and Reengineering (SANER)","volume":"6 1","pages":"138-147"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83482254","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}
