All the used materials, references to the literature and the work of others have been referred to. This thesis has not been presented for examination anywhere else. Author: Marina Nekrassova 08.01.2018 3 Abstract In software development, occasionally, in the course of software evolution, the functionality that previously worked as expected stops working. Such situation is typically denoted by the term regression. To detect regression faults as promptly as possible, many agile development teams rely nowadays on automated test suites and the practice of continuous integration (CI). Shortly after the faulty change is committed to the shared mainline, the CI build fails indicating the fact of code degradation. Once the regression fault is discovered, it needs to be localized and fixed in a timely manner. Fault localization remains mostly a manual process, but there have been attempts to automate it. One well-known technique for this purpose is delta debugging algorithm. It accepts as input a set of all changes between two program versions and a regression test that captures the fault, and outputs a minimized set containing only those changes that directly contribute to the fault (in other words, are failure-inducing).

  • Setting up Railpic] 12Th March 2020
    [Setting up RailPIC] 12th march 2020 1 Introduction This document provides a step by step guide to get a full DIY digital station for model trains running on an ARM device. The current development is based on my initial ideas to make rocrail (www.rocrail.net) run on a raspberry pi (www.raspberrypi.org/). The old document with such ideas – “Setting up rocpi v1.93” – is still available in the same repository where you have found this manual. Nowadays, the target HW used as basis for this project has shifted towards the odroid platform (http://www.hardkernel.com/main/main.php), specifically the C1 (C1+) board, thought all the instructions in this document are most probably equally suitable for the C2 board. The operating system used as basis has also shifted towards arch linux (https://archlinuxarm.org/), which in addition to be faster, more configurable and more updated than other tailored-made OS for other platforms – as Raspbian, it is available for multiple ARM devices. This allows to maintain this manual with detailed instructions both for odroid and raspberry pi (for testing purposes). The basic software to manage the trains layout is still rocrail, though, since the rpicd software emulates standard central stations, any other control software could be used too. The distribution of rpicd has also evolved towards the use of dockers (https://www.docker.com/) as main way to keep the software updated and independent on the HW and OS platform The final objective is to get the ARM device running on a very simple configuration, starting rocrail as a daemon, and enabling the launching of rocview through the activation of a digital input.

  • Case Sensitivity Versus Case Preservation in CIFS Server (Samba)
    Title: Case Sensitivity versus Case Preservation in CIFS Server (Samba) Author: Don McCall, Senior Support Engineer, Hewlett-Packard GSE Introduction The differences between PC and UNIX file systems are legion: how big they can be, what attributes they support, what characters are legal for file and directory names, etc. Samba does a truly heroic job of handling these differences. One way it does that is by recognizing and handling the difference between an operating system that is case sensitive (Unix), and one that simply preserves case (Microsoft Windows9x, WinNT, and Windows2000). In this article I'd like to examine this difference. Let us take for our study four filenames: FILEONE.TXT filetwo.txt Filethree.txt FiLeFoUr.TxT The first file (FILEONE.TXT) is all uppercase. The second file (filetwo.txt) is all lowercase. The third file is a special ‘case’ whose first letter ONLY is uppercase. The fourth file (FiLeFoUr.TxT) is a truly 'mixed' case, representative of the myriad case permutations a file name could take on. In Unix, if we used the touch command to create these four filenames, we would get exactly what we requested, i.e., a set of files in the directory whose names exactly matched the case we typed in, as we see here from the output of the UNIX ‘ll’ command: · rw-r-r-- 1 root sys 0 Dec 19 15:17 FILEONE.TXT · rw-r-r-- 1 root sys 0 Dec 19 15:18 FiLeFoUr.TxT · rw-r-r-- 1 root sys 0 Dec 19 15:18 Filethree.txt · rw-r-r-- 1 root sys 0 Dec 19 15:18 filetwo.txt Note that the Unix command 'll' doesn't alter this presentation – the filenames are shown just as they are represented in the file system.

  • Soc Concurrent Development Page 1 of 7
    SoC drawer: SoC concurrent development Page 1 of 7 SoC drawer: SoC concurrent development Establish a disciplined process for hardware and software co -design, integration, and test Sam Siewert ( [email protected] ), Adjunct Professor, University of Colorado Summary: A system-on-a-chip (SoC) can be more complex in terms of hardware-software interfacing than many earlier embedded systems because an SoC often includes multiple processor cores and numerous I/ O interfaces. The process of integrating and testing the firmware-hardware interface can begin early, but without good management and testing, the mutability of firmware and early stages of hardware design simulation can lead to disastrous setbacks for a project. This article teaches system designers about tools and methods to minimize project churn. View more content in this series Date: 20 Dec 2005 Level: Intermediate Activity: 687 views Comments: 0 ( Add comments ) Average rating (based on 17 votes) This article is the third in the SoC drawer series . The series aims to provide the system architect with a starting point and some tips to make system-on-a-chip (SoC) design easier. SoCs are either configurable or reconfigurable. Configurable SoCs are constructed from core logic that can be reused and modified for an application-specific integrated circuit (ASIC) implementation; reconfigurable SoCs use soft cores and field-programmable gate array (FPGA) fabrics that can be reprogrammed by simply downloading new in-circuit FPGA programming. The mutability of SoCs in terms of firmware and FPGA fabric is attractive because it allows for modification and addition of features. Likewise, for configurable SoCs, the mutability during early co-design and co-simulation allows for quick design changes in both hardware and firmware, making for a very agile project.

However these tools are most commonly used on plain textual documents such as source code. There exist few tools today for versioning fine-grained data such as graphical Simulink models. Since Simulink is widely used as a modeling tool in numerous engineering fields, nonetheless in the mechatronics field, it will be interesting to study the possibility of developing a tool for version control of graphical models. Two textual software configuration management (SCM) products, CVS and Rational Clear Case, were studied and their functionalities were analyzed, along with a different number of research topics on document versioning. The existing algorithms of ‘diff’ and ‘merge’ functions were also studied to give an understanding of how these functions work for text based documents. The knowledge gained from the tools, existing algorithms and literature on the subject were used to write MATLAB programs that perform diff and merge on Simulink models.
