Pro potřebu kontroly kvality kódu v Javě lze jednak využít funkce vývojového prostředí, ale také i samostatné programy, které kvalitu kódu hlídají - analyzéry kódu. Ty lze použít v podobě pluginů pro vývojová prostředí. V této práci jsem se primárně zaměřoval na vývojová prostředí NetBeans a Eclipse a jejich podporu pro různé analyzéry kódu (FindBugs, PMD, atd.) z oblasti open source. Práce se zabývá analýzou kontroly kvality ve vývojových prostředích a analyzérech kódu.

This thesis deals with a methodology for PHP web applications refactoring. The main objective is to propose such a methodology, and to apply it on a real project. The first chapter contains objectives, restrictions and contributions of the thesis. The research of the existing literature on similar topics follows in the second chapter. The third chapter comments on selected software development methodologies' approach to refactoring. The fourth chapter describes known code smells, and adds some new ones appearing particularly in PHP. Specifics of PHP refactoring are also described. The fifth chapter deals with the methodology proposal itself. It sums up requirements, deployment assumptions, the methodology principles and general characteristics. The next part contains the recommended procedure of PHP web applications refactoring with its parts commented farther on. These parts are mainly code smells identification techniques, prioritization and finally best practices. The chapter ends with this methodology deployment recommendations. The sixth chapter shows a practical usage of the proposed methodology when refactoring a real web application. The performed steps are explained in terms of the methodology. The chapter closes with observations gained during this refactoring.

The goal of this thesis is to create a tool for an optimization of code for the task-based parallel framework called Bobox. The optimizer tool reduces a number of short and long running tasks based on a static code analysis. Some cases of short-running tasks cause an unnecessary scheduling overhead. The Bobox scheduler can schedule a task even though the task does not have all input data. Unless, the scheduler has enough information not to schedule such task. In order to remove such short-running task, the tool analyses its input usage and informs the scheduler. Long-running tasks inhibit a parallel execution in some cases. A bigger task granularity can significantly improve execution times in a parallel environment. In order to remove a long-running task, the tool has to be able to evaluate a runtime code complexity and yield a task execution in the appropriate place. Powered by TCPDF (www.tcpdf.org)

Keeping a consistent coding style is an important part of having a maintainable code base. In times when software solutions become increasingly complicated this requirement is more important than ever. However, most commercially available coding productivity tools put a much bigger focus on refactoring and support of additional technologies than on maintaining consistent code style. We decided to remedy this situation by implementing a plugin-extensible toolset for Visual Studio focused on diagnosing and correcting code style violations in C# code bases. By completing our intent we created a tool that integrates seamlessly with Visual Studio and provides the user with effective and intuitive tools to improve the overall maintainability of their code base.

Title: Refactoring tree editor TrEd Author: Peter Fabian Department: Institute of Formal and Applied Linguistics Supervisor: doc. Ing. Zdenek Zabokrtsky, Ph.D., Institute of Formal and Applied Linguistics Abstract: The main goal of the thesis was to refactor tree editor TrEd, improve its modularity, maintainability and make its further development less difficult. Static and dynamic analysis of TrEd have been performed in order to help us find acrid spots in the source code. More than 230 subroutines and data structures have been moved between packages, 50 new packages and a test suite with more than 1,300 tests have been created. A new coding style have been chosen for further development and most severe violations of this standard have been fixed. After the changes done on the source code, it have been analyzed again and the results have been compared with the previous state. Keywords: Tree Editor TrEd, Perl, code refactoring, code analysis

Both uppermost open source compilers, GCC and LLVM, are mature enough to link-time optimize large applications. In case of large applications, we must take into account, except standard speed efficiency and memory consumption, different aspects. We focus on size of the code, cold start-up time, etc. Developers of applications often come up with ad-hoc solutions such as Elfhack utility, start-up of an application via a pre-loading utility and dlopen; prelinking and variety of different tools that reorder functions to fit the order of execution. The goal of the thesis is to analyse all existing techniques of optimization, evaluate their efficiency and design new solutions based on the link-time optimization platform.

Main objective of this thesis is to extend existing functionality of Integrated Development Environment (IDE) BlueJ with possibility of working with streams in an interactive mode. This new functionality helps to falicitate and improve teaching of programming within the First Architecture methodology. First part of this thesis deals with IDE BlueJ and discusses problematic software con-structions which don´t have sufficient support in interactive mode. Main focus is put on streams. Another part of this thesis suggests possible options for extension which should be integrated to the existing functionality. Following part focuses on analysis of the proposed changes and final part discusses implementation itself and describes author´s process of realization.

This work deals with localization and decoding of the linear barcode EAN-13 in the image. It describes types and qualities of barcodes and pose posibble accesses into the localization and decoding. The practical part concerns with the concept and implementation of the algorithm having regard to effectiveness for processing in real time. The localization is established on finding similar features of the barcode among the read rows of the image and decoding is made by finding of the supreme conformity towards referential code figures.

This master's thesis is about code ownership in software projects and creating a tool that would improve cooperation by identifying code owners. The theoretical foundation for code ownership starts from Extreme Programming, explaining models of code ownership and the impact of code ownership on cooperation among teams and team members. The concept is demonstrated on a concrete software firm, where a potential for improvement is identified. The potential is exploited by a software tool, which is designed in the this thesis. The tool is capable of identifying code owners and experts for specific areas in the code based on data gathered from a version control system. The resulting information is made easily accessible. The tool is used to conduct a code ownership research in several projects, which allows me to confirm accuracy of the results. Usability and benefits of the tool is discussed in the final chapter.

The goal of the diploma thesis "Upgrade of agile development support tool" is to study agile methodologies and its use in practice. Thesis is focused on the Scrum framework used by The Corporate Technology department of Siemens, s.r.o. in Brno. Furthermore the thesis analyzes and compares the most used software support tools for agile methodologies which also gives an inspiration for the upgrade of support tool used by the department of Siemens. Thesis identifies possible upgrades based on an analysis with the goal to make agile development even more effective. Results were consulted with the representative of the Siemens company and then modules for Code review and Retrospective were chosen to implement. Implementation consists even of some minor upgrades of the tool. Goals of all implemented upgrades were to save time, optimize administrative work and make development even more effective. Benefits and further upgrades are consulted at the end of the thesis.
