When synchronous advice execution is not a necessity, asynchronous advice execution has the potential to parallelize program and advice execution on multicores. However, asynchronous advice execution requires communication between threads, causing some overhead. In order to mitigate such overhead, we introduce buffered advice, a new AOP mechanism for aggregating advice invocations in a thread-local buffer, which is processed when it is full. For asynchronous processing of full buffers, the communication overhead is paid only once per buffer, instead of once per advice invocation. We present an enhanced AOP programming model and framework based on AspectJ, which ease the use of buffered advice and support pluggable, custom buffer processing strategies. As case study, we optimize an existing aspect for data race detection using buffered advice. A thorough evaluation with standard benchmarks confirms that the use of buffered advice yields significant speedup on multicores.","PeriodicalId":353153,"journal":{"name":"Aspect-Oriented Software Development","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131059397","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}

This has led to a large amount of proposals for alternative composition techniques, including many variations of message dispatch, inheritance, and aspect mechanisms. This paper makes the case that there is no single perfect composition technique that suits every situation, since different techniques incur different trade-offs. The proper composition technique to use depends on the particular design problem and its requirements (e.g. w.r.t. adaptability, reusability, understandability, robustness, etc. of the various elements of the design). However, most programming languages limit the available composition techniques to a very few. To address this, we propose a novel composition model. The model provides dedicated abstractions that can be used to express a wide variation of object composition techniques (\"composition operators\"). Examples include various forms of inheritance, delegation, and aspects. The proposed model unifies objects (with encapsulated state and a message interface) and composition operators; composition operators are specified as first-class citizens. Multiple composition operators can be combined within the same application, and composition operators can even be used to compose new composition operators from existing ones. This opens new possibilities for developing domain-specific composition operators, taxonomies of composition operators, and for reuse and refinement of composition operators. To validate and experiment with the proposed model, we have designed and implemented a simple language, that we also use in this paper to show concrete examples.","PeriodicalId":353153,"journal":{"name":"Aspect-Oriented Software Development","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115286762","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}

Some patterns are useful to the software, and may be modularized. Others are detrimental to the software, such as patterns that represent defects. In this case, it is useful to study the occurrences of such patterns, to identify properties such as when and why they are introduced, how long they persist, and the reasons why they are corrected.\u0000 To enable studying pattern occurrences over time, we propose a tool, Herodotos, that semi-automatically tracks pattern occurrences over multiple versions of a software project, independent of other changes in the source files. Guided by a user-provided configuration file, Herodotos builds various graphs showing the evolution of the pattern occurrences and computes some statistics. We have evaluated this approach on the history of a representative range of open source projects over the last three years. For each project, we track several kinds of defects that have been found by pattern matching. This tracking is done automatically in 99% of the occurrences. The results allow us to compare the evolution of the selected projects and defect kinds over time.","PeriodicalId":353153,"journal":{"name":"Aspect-Oriented Software Development","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132116114","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}

Unfortunately, both commercial and academic model composition tools suffer from the composition conflict problem. That is, models to-be-composed may conflict with each other and these conflicts must be resolved. In practice, detecting and resolving conflicts is a highly-intensive manual activity. In this paper, we investigate whether aspect-orientation reduces conflict resolution effort as improved modularization may better localize conflicts. The main goal of the paper is to conduct an exploratory study to analyze the impact of aspects on conflict resolution. In particular, model compositions are used to express the evolution of architectural models along six releases of a software product line. Well-known composition algorithms, such as override, merge and union, are applied and compared on both AO and non-AO models in terms of their conflict rate and effort to solve the identified conflicts. Our findings identify specific scenarios where aspect-orientation properties, such as obliviousness and quantification, result in a lower (or higher) composition effort.","PeriodicalId":353153,"journal":{"name":"Aspect-Oriented Software Development","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125594397","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 they appeared to be fruitful to develop or improve distributed component infrastructures or application servers, those systems are not underpinned with a formal semantics and so do not permit to establish properties on the code to be executed. This paper introduces the aspect join calculus -- an aspect-oriented and distributed language based on the join calculus, a member of the π-calculus family of process calculi suitable as a programming language. It provides a first formal theory of distributed AOP as well as a base language in which many features of previous distributed AOP systems can be formalized.\u0000 The semantics of the aspect join calculus is given by a (chemical) operational semantics and a type system is developed to ensure properties satisfied by aspects during the execution of a process. We also give a translation of the aspect join calculus into the core join calculus. The translation is proved to be correct by a bisimilarity argument. In this way, we provide a well-defined version of a weaving algorithm which constitutes the main step towards an implementation of the aspect join calculus directly in JoCaml.\u0000 We conclude this paper by showing that despite its minimal definition, the aspect join calculus is a convenient language in which existing distributed AOP languages can be formalized. Indeed, many features (such as remote pointcut, distributed advice, migration of aspects, asynchronous and synchronous aspects, re-routing of messages and distributed control flow) can be defined in this simple language.","PeriodicalId":353153,"journal":{"name":"Aspect-Oriented Software Development","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114354514","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}
