Buildbot: a Continuous Integration System
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. -

Teixeira and Karsten Journal of Internet Services and Applications (2019) 10:7 Journal of Internet Services https://doi.org/10.1186/s13174-019-0105-z and Applications RESEARCH Open Access Managing to release early, often and on time in the OpenStack software ecosystem José Apolinário Teixeira* and Helena Karsten Abstract The dictum of “Release early, release often.” by Eric Raymond as the Linux modus operandi highlights the importance of release management in open source software development. However, there are very few empirical studies addressing release management in this context. It is already known that most open source software communities adopt either a feature-based or time-based release strategy. Both have their own advantages and disadvantages that are also context-specific. Recent research reports that many prominent open source software projects have overcome a number of recurrent problems by moving from feature-based to time-based release strategies. In this longitudinal case study, we address the release management practices of OpenStack, a large scale open source project developing cloud computing technologies. We discuss how the release management practices of OpenStack have evolved in terms of chosen strategy and timeframes with close attention to processes and tools. We discuss the number of practical and managerial issues related to release management within the context of large and complex software ecosystems. Our findings also reveal that multiple release management cycles can co-exist in large and complex software -
Magic Quadrant for Application Release Automation
Magic Quadrant for Application Release Automation Published: 27 September 2017 ID: G00315074 Analyst(s): Colin Fletcher, Laurie F. Wurster The ARA market is rapidly evolving in response to growing enterprise requirements to both scale DevOps initiatives and improve release management agility across multiple cultures, processes and generations of technology. This research helps I&O leaders make better-informed decisions. Strategic Planning Assumption By 2020, 50% of global enterprises will have implemented at least one application release automation solution, up from less than 15% today. Market Definition/Description Application release automation (ARA) tools provide a combination of automation, environment modeling and release coordination capabilities to simultaneously improve the quality and the velocity of application releases. ARA tools enable best practices in moving application-related artifacts, applications, configurations and even data together across the application life cycle process. These tools are a key part of enabling the DevOps goal of achieving continuous delivery with large numbers of rapid, small releases. Approximately seven years old, the ARA solution market reached an estimated $228.2 million in 2016, up 31.4% from $173.6 million in 2015. The market is continues to be expected to grow at an estimated 20% compound annual growth rate (CAGR) through 2020. Magic Quadrant Figure 1.

Apache Ant Best Practices
08_Lee_ch05.qxd 5/3/06 5:12 PM Page 81 C HAPTER 5 Apache Ant Best Practices This chapter looks in more detail at some best practices for using Ant on real projects. First I describe the use of property files to enable configuration of the build process depending on a user’s role and requirements. I then describe how best to integrate Ant with IBM Rational ClearCase. Finally, I look at some general best practices for supporting the build process on large projects. Aims of This Chapter Apache Ant is a powerful build tool with significant built-in capabilities. However, a few capabil- ities and best practices stand out; they are described here. After reading this chapter, you will be able to • Understand what Ant property files are and how they can be used to make build scripts more maintainable. • Understand how to use Ant’s capabilities to better integrate with IBM Rational ClearCase. • Implement Ant build files that support reuse and maintainability on large projects. This chapter assumes that you are familiar with the basic concepts of Apache Ant that were discussed in Chapter 4, “Defining Your Build and Release Scripts.” Property Files From the perspective of Chapter 4, an Ant build.xml file is a single centralized build file that defines a repeatable process for bringing together an application, usually producing some form of 81 08_Lee_ch05.qxd 5/3/06 5:12 PM Page 82 82 Chapter 5 Apache Ant Best Practices executable output. Although a single build.xml file can be enough to drive the build process, in practice it can quickly become large and unwieldy. -
CI-CD-For-Infrastructure-Configuration
Abstract & Overview Organizations of all sizes, from the leanest startup to the stodgiest enterprise, use CI/CD practices to greatly improve production and delivery of software. This yields higher- quality software at a lower cost and allows businesses to deliver ideas to market faster. As development teams adopt CI/CD practices, they start delivering new applications and releases faster and faster. This constantly changing software inevitably requires changes to infrastructure and configuration, but many operations teams aren’t accustomed to the pace—nor do they have the proper tools required. Trying to directly apply successful CI/CD practices for applications is highly unlikely to yield success for infrastructure and configuration changes. In this guide, we explore: • How and why CI/CD has been so successful for application changes • Infrastructure and configuration changes as a new bottleneck • Challenges with CI/CD for infrastructure and configuration changes • How to overcome challenges and implement CI/CD for infrastructure We include a hands-on guide for how to implement this with BuildMaster and Otter. You can do everything in this guide with BuildMaster Free and Otter Free editions! About Inedo, Otter, and BuildMaster We help organizations make the most of their Windows technology and infrastructure through our Windows-native and cross-platform DevOps tools. • BuildMaster, a tool designed to implement CI/CD, automates application releases. • Otter manages infrastructure. Harnessing the power of both tools allows users to manage infrastructure while enjoying all the benefits of CI/CD.

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. -
