    Buildbot: A continuous integration system Krzysztof Voss January, 2013 Outline • Testing and Continuous Integration • Introduction to Buildbot • BuildMaster • BuildMaster components • BuildSlave • Installation and Usage 1 Testing and continuous integration Tests: • the best specification • safety-net for refactoring • bug identification Tests are the most effective if we: • run them often • run them on different machines/environments • can easily see their results 2 The most straightforward approach would entail: • logging in to different machines • fetching the newest source code • running tests • analyzing their output In case we want to test a few environments, repeating the above steps is tedious. Developers do not focus on the code, instead they run tests. A continuous integration system performs all of these steps for us, so developers can focus on their code. 3 Introduction to Buildbot: Features • run builds on a variety of BuildSlave platforms • arbitrary build process: handles projects using C, Python, . • minimal host requirements: python and Twisted • BuildSlave can be behind a firewall if they can still do checkout • status delivery through web page, email, IRC, other protocols • track builds in progress, provide estimated completion time • flexible configuration by subclassing generic build process classes 4 • debug tools to force a new build, submit fake Changes, query BuildSlave status • released under the GPL source: http://buildbot.net/buildbot/docs/current/manual/introduction.html 5 Introduction to Buildbot: Overview system overview source: http://buildbot.net/buildbot/docs/0.8.1/full.html 6 BuildMaster BuildMaster components source: http://buildbot.net/buildbot/docs/0.8.1/full.html 7 BuildMaster BuildMaster: • holds the configuration of the entire system.

Now-a-days more than ever, DevOps [Development + Operations] has gained a tremendous amount of attention in 2. SCM software industry. Selecting the tools for building the DevOps Source code management (SCM) is a software tool used for pipeline is not a trivial exercise as there are plethora’s of tools development, versioning and enables team working in available in market.

Abstract A Vehicular Ad-hoc Network (VANET) is a system of nodes (vehi- cles) that are being connected with each other by wireless technolo- gies. Usually the nodes are moving with very high speeds and, thus, the topology is unpredictable and frequently changing. Such networks can be stand alone and making paths along vehicles or may be con- nected by an infrastructure internet.

  • This Book Doesn't Tell You How to Write Faster Code, Or How to Write Code with Fewer Memory Leaks, Or Even How to Debug Code at All
    Practical Development Environments By Matthew B. Doar ............................................... Publisher: O'Reilly Pub Date: September 2005 ISBN: 0-596-00796-5 Pages: 328 Table of Contents | Index This book doesn't tell you how to write faster code, or how to write code with fewer memory leaks, or even how to debug code at all. What it does tell you is how to build your product in better ways, how to keep track of the code that you write, and how to track the bugs in your code. Plus some more things you'll wish you had known before starting a project. Practical Development Environments is a guide, a collection of advice about real development environments for small to medium-sized projects and groups. Each of the chapters considers a different kind of tool - tools for tracking versions of files, build tools, testing tools, bug-tracking tools, tools for creating documentation, and tools for creating packaged releases. Each chapter discusses what you should look for in that kind of tool and what to avoid, and also describes some good ideas, bad ideas, and annoying experiences for each area. Specific instances of each type of tool are described in enough detail so that you can decide which ones you want to investigate further. Developers want to write code, not maintain makefiles. Writers want to write content instead of manage templates. IT provides machines, but doesn't have time to maintain all the different tools. Managers want the product to move smoothly from development to release, and are interested in tools to help this happen more often.

  • Design and Implementation of a Continuous Integration System
    Prakash Acharya DESIGN AND IMPLEMENTATION OF A CONTINUOUS INTEGRATION SYSTEM DESIGN AND IMPLEMENTATION OF A CONTINUOUS INTEGRATION SYSTEM Prakash Acharya Bachelor’s Thesis Spring 2019 Information Technology Oulu University of Applied Sciences ABSTRACT Oulu University of Applied Sciences Information Technology, Internet Services Author: Prakash Acharya Title of the bachelor’s thesis: Design and Implementation of a Continuous Integration System Supervisor: Lasse Haverinen Term and year of completion: Spring 2019 Number of pages: 43 Not having an automated test system in the software development process leaves space for errors to go unnoticed in code review, which can break a codebase if integrated. The aim of the Bachelor’s thesis was to design and implement a Continuous Integration system where tests and build tasks could be automated. The Buildbot framework was used as a Continuous Integration and automation framework. The Ansible playbook was used for automating the deployment of Buildbot configuration. The Buildbot configuration was created in such a way that it allows Buildbot instances to be created easily and in a configurable manner. In addition, automation of the Python static code analysis tool, Prospector, was added to the Continuous Integration system. The result of having a configurable Buildbot system was that the developers could start adding automation tasks and test and verify their change without affecting the production instance. Having an automated static code analysis run on changes brings into attention potential problems and error before they are integrated. Even though the Buildbot system is not taken into use, it was tested in a test environment and it is shown to work.

  • When Developers Build Software, They're Able to Keep Track of All The
    < Day Day Up > Practical Perforce By Laura Wingerd ............................................... Publisher: O'Reilly Pub Date: November 2005 Print ISBN-10: 0-596-10185-6 Print ISBN-13: 978-0-59-610185-5 Pages: 358 Table of Contents | Index When developers build software, they're able to keep track of all the different versions and all the components they use with software configuration management (SCM) systems. One of the more popular SCM products is Perforce. Authored by Perforce's own VP of product technology, Practical Perforce is the ideal complement to the existing product manual, focusing less on the 'how" and more on the "why" and "when." The book is not only a helpful introduction to Perforce, it's an enlightening resource for those already familiar with this versatile SCM product. Whether you're a programmer, product manager, or build engineer, you stand to benefit from the many insider tips and ideas presented in this convenient guide. Practical Perforce is divided into two main parts. Part I offers a whirlwind technical tour, complete with careful descriptions of basic and advanced Perforce commands designed to give you a baseline knowledge. Part II describes the big picture-using Perforce in a collaborative software development. It outlines recommended best practices and quickly shows how to implement them with the Perforce operations introduced in Part I. Throughout the book, you'll learn how to maximize Perforce so it completes tasks like these in the most efficient manner possible: Keep track of changes as you conduct concurrent parallel work on files Log activity Generate reports on who did what when Compare, merge and branch files Store files and file configurations Restore lost bug fixes Recognizing the pitfalls and practices of an SCM system like Perforce is absolutely essential to producing good software.
