Software Evolution Analysis for Team Foundation Server Software evolution analysis for Team Foundation Server Bachelor thesis University of Groningen July 2013 Author: Joost Koehoorn Primary supervisor: Prof. dr. Alexandru C. Telea Secondary supervisor: Prof. dr. Gerard R. Renardel de Lavalette Abstract To understand how software evolves, visualizing its history is a valuable approach to get an in-depth view of a software project. SolidTA, a software evolution visualization application, has been made to obtain these insights by extracting data from version control systems such as SVN and Git. Companies with large, proprietary codebases are often required to use an all-in-one solution such as Microsoft’s Team Foundation Server. During this project I have been looking into ways of extending SolidTA with the ability to import history from TFS. This has been achieved by utilizing the TFS SDK in order to import all necessary history information into SolidTA’s data domain. Another key part in understanding software evolution are source metrics, such as lines of code and McCabe’s complexity measure. The primary language of TFS projects is C# for which an analyzer was not available in SolidTA, so I have researched existing analyzers and then decided to implement an analyzer myself for greater control over the available metrics, based on an existing C# parser. This has become a fast tool that provides extensive per-file-metrics, for which SolidTA has been extended in order to visualize them. The TFS integration and C# analyzation have been field-tested on a codebase of RDW ("Rijksdienst van Wegverkeer"), which spans a history of circa six years. This test has shown that the implemented solutions are fast and reliable. i.

Software evolution analysis for TFS 1. Introduction Chapter 1 Introduction Version control systems (VCS) have become more and more important for software projects over the last couple of years. SolidTA is an application designed to perform analyzation on the evolution of large software projects. It gives insights in many differ- ent metrics and it is highly sophisticated in being able to combine many of such metrics to answer specific questions about software projects. This helps in understanding how a project is maintained, and may help in improving the development process. One of the goals of SolidTA is to provide a way to gain more insights into different types of software projects. So, not only can it be used to analyze just one individual project, but also for a comparison between multiple projects which may differ in many ways. This includes comparisons between open source and proprietary software. Since many large proprietary software companies are bound to use TFS, it is not currently possible do that, since SolidTA only has support for SVN. Patterns in how the VCS is used may be analyzed, but SolidTA offers a lot more by analyzing the actual code contents of a repository throughout the complete history. To accomplish this, static code analysis tools are used to calculate metrics from source files. The analysis tool that is currently used by SolidTA is CCCC1 and this tool only supports C, C++ and Java code. As TFS mainly targets C# applications, a solution has to be found to also support C# in SolidTA. In this thesis I research possibilities on providing an interface between TFS and SolidTA. In chapter 2 I look at related work, to continue with the conceptual design in chapter 3. Chapter 4 investigates a couple of approaches for data importing from TFS, and the best fitting solution is implemented and integrated in SolidTA. Then in chapter 5, options for C# analyzation are discussed and the implementation of the solution is given. To validate the implemented solutions, chapter 7 analyzes a large software project maintained in TFS. 1http://cccc.sourceforge.net 1 Software evolution analysis for TFS 2. Related Work Chapter 2 Related Work As visualization is an active research area, earlier research has been undertaken that is relevant to what is to be accomplished by this project. In this chapter I discuss findings from these earlier research projects and the main architecture and features of TFS. 2.1 SolidTA The provided software itself, SolidTA, is the result of research done by Voinea et al. [5]. In this paper, a new way of visualizing code evolution was proposed and a tool to support and validate their proposal was announced in the form of CVSgrab. This tool can be seen as the predecessor of SolidTA, which is a commercial release accommodating various new features compared to CVSgrab, but the visualization technique has stayed the same. Figure 2.1 shows the GUI of SolidTA, highlighting some important views. As SolidTA’s main goal is to visualize evolution of files, displayed in (a), the versions of files are visualized in (b) where in-depth insights are provided by various metrics (c), representing certain attributes of a version. 2 Software evolution analysis for TFS 2. Related Work Figure 2.1: Overview of SolidTA The visualization technique as described in aforementioned paper and used in SolidTA draws files as fixed height horizontal stripes —as seen in view (b)—, each divided up into several segments, representing all versions of the file. These segments are ordered according to creation time and the length correspond to the lifetime of the version. The paper also gives a formal definition of a repository R with NF files: R = fFi j i = 1::NF g (2.1) Each files Fi is then defined as a set of NVi versions: Fi = fVij j j = 1::NVig (2.2) These definitions are repository agnostic, whereas the exact definition of a version is dependent on the type of repository. SolidTA is flexible to support multiple version definitions by offering support for plugins that may store all kinds of data offered by a repository. 3 Software evolution analysis for TFS 2. Related Work 2.2 Repository mining Data mining is the process of extracting relevant information from version control sys- tems. This is a hard problem since those tools are primarily designed to commit changes and rollback to previous versions, they usually do not have interfaces for extraction of data [6]. Also, large software projects may span over a decade of history, covering thou- sands of files and hundreds of thousands of versions. These large amounts of data are mostly stored on a separate server and can thus not be requested on the fly, but have to be imported and stored locally first. Another problem exists when mining data from different types of repositories, because each VCS has its own features, libraries and APIs, if any. For an application such as SolidTA, these different types of repositories have to be imported into one central data domain, so differences have to be normalized. 2.3 Team Foundation Server Microsoft’s Team Foundation Server1 is much more than just a version control system. It also incorporates project management tools, a build server and continuous integration server, among more technical features, such as an SDK so external applications can extend and interact with TFS [3].

  • Building Openjfx
    Building OpenJFX Building a UI toolkit for many different platforms is a complex and challenging endeavor. It requires platform specific tools such as C compilers as well as portable tools like Gradle and the JDK. Which tools must be installed differs from platform to platform. While the OpenJFX build system was designed to remove as many build hurdles as possible, it is necessary to build native code and have the requisite compilers and toolchains installed. On Mac and Linux this is fairly easy, but setting up Windows is more difficult. If you are looking for instructions to build FX for JDK 8uNNN, they have been archived here.

  • SME: a High Productivity FPGA Tool for Software Programmers
    1 SME: A High Productivity FPGA Tool for Software Programmers Carl-Johannes Johnsen∗, Alberte Thegler∗, Kenneth Skovhede∗, and Brian Vinter† {∗Niels Bohr Institute, University of Copenhagen, † Faculty of Technical Sciences, Aarhus University} Abstract—For several decades, the CPU has been the standard model to use in the majority of computing. While the CPU does excel in some areas, heterogeneous computing, such as reconfigurable hardware, is showing increasing potential in areas like parallelization, performance, and power usage. This is especially prominent in problems favoring deep pipelining or tight latency requirements. However, due to the nature of these problems, they can be hard to program, at least for software developers. Synchronous Message Exchange (SME) is a runtime environment that allows development, testing and verification of hardware designs for FPGA devices in C#, with access to modern debugging and code features. The goal is to create a framework for software developers to easily implement systems for FPGA devices without having to obtain heavy hardware programming knowledge. This article presents a short introduction to the SME model as well as new updates to SME. Lastly, a selection of student projects and examples will be presented in order to show how it is possible to create quite complex structures in SME, even by students with no hardware experience. Index Terms—Reconfigurable hardware, Modeling techniques, Simulation, Verification, Hardware description languages, Computers and Education ✦ 1 INTRODUCTION The use of CPUs for programming is an incredibly flexi- simpler than other methods [4] and initial results also show ble approach that allows the same hardware to be deployed that the SME model allows students familiar with sequential in many different scenarios, and also enables seamless up- programming to pick up the parallelism [5].

Ana-Maria Oprescu, [email protected] Host supervisor: dr. Magiel Bruntink, [email protected] Host organisation: Software Improvement Group, Inc., https://www.sig.eu Universiteit van Amsterdam Faculteit der Natuurwetenschappen, Wiskunde en Informatica Master Software Engineering http://www.software-engineering-amsterdam.nl Abstract Undoubtedly, refactoring can have a positive effect on overall system quality, and it is a critical part of the work cycle of every developer. However, finding the right refactoring opportunities can be a difficult task. This is particularly the case for refactorings related to overall system structure. One of the best ways to address such issues is to apply the move module refactoring. In this thesis, we propose a way of automatically detecting refactoring opportunities for move module refactorings in the context of the C# language using a Compiler as a Service (CaaS) - Roslyn. We evaluate our approach using seven open source projects and an expert panel. The results from these validation experiments showed our approach as promising - the group of experts found more than half of the proposed refactorings useful. 1 Contents Abstract 1 Acronyms 5 1 Introduction 6 1.1 Problem analysis....................................... 6 1.2 Research questions...................................... 7 1.3 Solution outline........................................ 8 1.4 Definitions........................................... 8 1.5 Outline ............................................ 8 2 Background 10 2.1 Refactoring .......................................... 10 2.2 Code smells.......................................... 10 2.3 Move module refactoring................................... 11 2.4 Better Code Hub (BCH) and the SIG Maintainability Model .............

  • Assessment of Roslyn Analyzers for Visual Studio
    ASSESSMENT OF ROSLYN ANALYZERS FOR VISUAL STUDIO Jurgen¨ Sundstrom¨ Bachelor esis, 15 credits Bachelor Of Science Programme in Computing Science 2019 Abstract Soware security is an ever growing subject that is geing more important as we implement more soware into our daily lives. We want to protect our personal information and keep our privacy intact. Since our soware systems are geing more complex as well, soware developers need support in the form of tools that can help them to keep the soware free from vulnerabilities. ere are many such tools available but the focus of this study is investigating the performance of the fairly new Roslyn analyzers for security that can be embedded into Visual Studio. Since Roslyn analyzers for security are, in the time of writing (June 2019), not subject in any released studies the goal is to lay a foundation for future work regarding these types of tools. erefore three Roslyn analyzers for security are being compared, on source code in the C# programming language provided by the SAMATE project, both with each other but also against classic static analysis tools. Four vulnerability categories from the SAMATE test suite for C# are used to in- vestigate the analyzers, namely OS command injection (CWE-078), SQL Injection (CWE-089), XML Injection (CWE-091) and Cryptography algorithms (CWE-327). e performance of the analyzers is measured with the metrics recall, precision and F-measure which are commonly used in other similar studies and makes it possible to compare the results obtained within this study with the results of other studies within the eld.
