Debugging Data Flows in reactive Programs 18

Debugging Data Flows in Reactive Programs

40th ACM/IEEE International Conference on Software Engineering (ICSE)

作者： Banken, Herman Meijer, Erik Gousios, Georgios Delft Univ Technol Delft Netherlands

ISBN: (纸本)9781450356381

reactive programming is a style of programming that provides developers with a set of abstractions that facilitate event handling and stream processing. Traditional debug tools lack support for reactive programming, leading developers to fallback to the most rudimentary debug tool available: logging to the console. In this paper, we present the design and implementation of RxFiddle, a visualization and debugging tool targeted to Rx, the most popular form of reactive programming. RxFiddle visualizes the dependencies and structure of the data flow, as well as the data inside the flow. We evaluate RxFiddle with an experiment involving 111 developers. The results show that RxFiddle can help developers finish debugging tasks faster than with traditional debugging tools.

A reactive Language for Analyzing Cloud Logs 5

A Reactive Language for Analyzing Cloud Logs

5th ACM SIGPLAN International Workshop on reactive and Event-Based Languages and Systems (REBLS)

Log analysis is required in many domains, and especially in the emerging field of cloud computing. Cloud applications are often built by composing diverse services. When something goes wrong, finding the root cause of the problem can be difficult. Many services are only reachable through their Application programming Interfaces (APIs) with no possibility for live introspection. In this context, logs become an essential tool for monitoring and debugging. Cloud services typically generate very large quantities of log messages, with formats that may not be well specified and may vary over time. In this paper, we present CloudLens, a language for the analysis of semi-structured textual data as found in logs, and specify its formal semantics. CloudLens is a reactive language and views logs as streams of objects. Our objective is to facilitate exploring the contents of logs interactively and to write reusable analyses succinctly, using familiar constructs. We implemented an interpreter for the Apache Zeppelin notebook to provide an interactive IDE. Our prototype implementation is open source and we report on a detailed case study using logs from the Apache OpenWhisk project.

reactive model transformation with ATL

Model-driven applications may maintain large networks of structured data models and transformations among them. The development of such applications is complicated by the need to reflect on the whole network any runtime update performed on models or transformation logic. If not carefully designed, the execution of such updates may be computationally expensive. In this paper we propose a reactive paradigm for programming model transformations, and we implement a reactive model-transformation engine. We argue that this paradigm facilitates the development of autonomous model-driven systems that react to update and request events from the host application by identifying and performing only the needed computation. We implement such approach by providing a reactive engine for the An transformation language. We evaluate the usage scenarios that this paradigm supports and we experimentally measure its ability to reduce computation time in transformation-based applications. (C) 2016 Elsevier B.V.

Designing Modular Software: A Case Study in Introductory Statistics

JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS 2017年第3期26卷 493-500页

作者： Hare, Eric Kaplan, Andee Iowa State Univ Dept Stat Ames IA 50011 USA

Modular programming is a development paradigm that emphasizes self-contained, flexible, and independent pieces of functionality. This practice allows new features to be seamlessly added when desired, and unwanted features to be removed, thus simplifying the software's user interface. The recent rise of web-based software applications has presented new challenges for designing an extensible, modular software system. In this article, we outline a framework for designing such a system, with a focus on reproducibility of the results. We present as a case study a Shiny-based web application called intRo, that allows the user to perform basic data analyses and statistical routines. Finally, we highlight some challenges we encountered, and how to address them, when combining modular programming concepts with reactive programming as used by Shiny. Supplementary material for this article is available online.

MIMICKING QUANTUM MECHANICS USING reactive programming

INTERNATIONAL JOURNAL OF MODERN PHYSICS C 2011年第6期22卷 635-648页

作者： Boussinot, Frederic Inst Natl Rech Informat & Automat INDES Team F-06902 Sophia Antipolis France

We implement in a reactive programming framework a system mimicking three aspects of quantum mechanics: self-interference, state superposition, and entanglement. The system basically consists in a cellular automaton embedded in a synchronous environment which defines global discrete instants and broadcast events. The implementation shows how a simulation of fundamental aspects of quantum mechanics can be obtained from the synchronous parallel combination of a small number of elementary components.

First-Class reactive Programs for CPS 4

First-Class Reactive Programs for CPS

4th ACM SIGPLAN International Workshop on reactive and Event-Based Languages and Systems (REBLS)

作者： De Troyer, Christophe Nicolay, Jens De Meuter, Wolfgang Vrije Univ Brussel Software Languages Lab Brussels Belgium

Cyber-Physical Systems (CPS) are comprised of a network of devices that vary widely in complexity, ranging from simple sensors to autonomous robots. Traditionally, controlling and sensing these devices happens through API communication, in either push or pull-based fashion. We argue that the computational power of these devices is converging to the point where they can do autonomous computations. This allows application programmers to run programs locally on the sensors, thereby reducing the communication and workload of more central command and control entities. This work introduces the Potato framework that aims to make programming CPS systems intuitively easy and fast. Potato is based on three essential mechanisms: failure handling by means of leasing, distribution by means of first-class reactive programs, and intentional retroactive designation of the network by means of capabilities and dynamic properties. In this paper we focus on the reactive capabilities of our framework. Potato enables programmers to create and deploy first-class reactive programs on CPS devices at run time, abstracting away from the API approach. Each node in the network is equipped with a minimal actor-based middleware that can execute first-class reactive programs. We have implemented Potato as a library in Elixir and have used it to implement several small examples.

The Declarative Nature of Implicit Layer Activation 9

The Declarative Nature of Implicit Layer Activation

引用

9th International Workshop on Context-Oriented programming (COP)

作者： Ramson, Stefan Lincke, Jens Hirschfeld, Robert Univ Potsdam Hasso Plattner Inst Potsdam Germany

ISBN: (纸本)9781450349710

Context-oriented programming (coP) directly addresses context variability by providing dedicated language concepts: layers, units of modularity, store context-dependent behavior. During runtime, layers can be applied dynamically depending on the current context of the program. Various activation means for layers have been proposed. Most of them require developers to model context switches explicitly. In contrast, implicit layer activation (ILA) allows developers to bind the activation status of a layer to a boolean predicate. The associated layer stays automatically active as long as the given predicate evaluates to true. Despite its declarative semantics, ILA is usually implemented in an imperative fashion. In this paper, we present and compare two implementation variants for ILA in ContextJS: an imperative and a reactive implementation. Furthermore, we discuss their trade-offs regarding code complexity as well as runtime overhead.
