Analysis of Devops Tools to Predict an Optimized Pipeline by Adding Weightage for Parameters
International Journal of Computer Applications (0975 – 8887) Volume 181 – No. 33, December 2018 Analysis of DevOps Tools to Predict an Optimized Pipeline by Adding Weightage for Parameters R. Vaasanthi V. Prasanna Kumari, PhD S. Philip Kingston Research Scholar, HOD, MCA Project Manager SCSVMV University Rajalakshmi Engineering Infosys, Mahindra City, Kanchipuram College, Chennai Chennai ABSTRACT cloud. 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. It requires thought, planning, and multiple locations to work together more effectively. This preferably enough time to investigate and consult other plays a vital role in increasing team’s productivity. Some of people. Unfortunately, there isn’t enough time in the day to the SCM tools, considered for this study are GIT, SVN, CVS, dig for top-rated DevOps tools and its compatibility with ClearCase, Mercurial, TFS, Monotone, Bitkeeper, Code co- other tools. Each tool has its own pros/cons and compatibility op, Darcs, Endevor, Fossil, Perforce, Rational Synergy, of integrating with other tools. The objective of this paper is Source Safe, and GNU Bazaar. Table1 consists of SCM tools to propose an approach by adding weightage to each with weightage. parameter for the curated list of the DevOps tools. 3. BUILD Keywords Build is a process that enables source code to be automatically DevOps, SCM, dependencies, compatibility and pipeline compiled into binaries including code level unit testing to ensure individual pieces of code behave as expected [4]. -
Bluej Teamwork Repository Configuration
BlueJ Teamwork Repository Configuration Version 2.0 for BlueJ Version 2.5.0 (and 2.2.x) Davin McCall School of Engineering & IT, Deakin University 1 Introduction This document gives a brief description of how you might set up a version control repository for use with BlueJ’s teamwork features. It is intended mainly as a “quick start” guide and not as a complete reference – for that you should refer to the version control software documentation (i.e. the CVS manual or the Subversion manual) – but it does explain some BlueJ-specific concepts (such as how BlueJ supports the notion of student groups or teams). Setting up a repository usually requires a server to which you have “root” or administrator access. This may mean that you need to ask a Systems Administrator to set up the repository for you. Since BlueJ version 2.5.0, both Subversion and CVS are supported version control systems. BlueJ version 2.2.x supports only CVS. BlueJ versions prior to 2.2.0 did not support teamwork features. Chapters 2 and 3 explain how to set up and test a repository using CVS. Chapter 4 then covers the equivalent steps for using Subversion. 2 Setting up a simple single user CVS repository for testing the BlueJ teamwork features 2.1 Setting up the repository server On Unix / Linux / MacOS X: You must have the CVS software installed on the machine you intend to use as a server. There is a good chance that it is already installed, but if not, your vendor or distribution provider will almost certainly provide packages that can be installed. -

Subversionin käyttö kuitenkin johtaa ylimääräisiin ylläpitotoimiin LUTin tietohallinnolle. Lisäksi Subversionin julkaisun jälkeen on tullut uusia versionhallintajärjestelmiä ja tässä työssä tutkitaankin, olisiko Subversion syytä vaihtaa johonkin toiseen versionhallintajärjestelmään opetuskäytössä. Työn tavoitteena on löytää opetuskäyttöön parhaiten soveltuva versionhallintajärjestelmä ja tuottaa sille opetusmateriaalia. Työssä havaittiin, että Git on suosituin versionhallintajärjestelmä ja se on myös suhteellisen helppo käyttää. Lisäksi GitLab on tutkimuksen mukaan Suomen yliopistoissa käytetyin ja ominaisuuksiltaan ja hinnaltaan sopivin Gitin web-käyttöliittymä. Näille tehtiin -

CSE 391 Lecture 9
CSE 391 Lecture 9 Version control with Git slides created by Ruth Anderson & Marty Stepp, images from http://git-scm.com/book/en/ http://www.cs.washington.edu/391/ 1 Problems Working Alone • Ever done one of the following? . Had code that worked, made a bunch of changes and saved it, which broke the code, and now you just want the working version back… . Accidentally deleted a critical file, hundreds of lines of code gone… . Somehow messed up the structure/contents of your code base, and want to just “undo” the crazy action you just did . Hard drive crash!!!! Everything’s gone, the day before deadline. • Possible options: . Save as (MyClass-v1.java) • Ugh. Just ugh. And now a single line change results in duplicating the entire file… 2 Problems Working in teams . Whose computer stores the "official" copy of the project? • Can we store the project files in a neutral "official" location? . Will we be able to read/write each other's changes? • Do we have the right file permissions? • Lets just email changed files back and forth! Yay! . What happens if we both try to edit the same file? • Bill just overwrote a file I worked on for 6 hours! . What happens if we make a mistake and corrupt an important file? • Is there a way to keep backups of our project files? . How do I know what code each teammate is working on? 3 Solution: Version Control • version control system: Software that tracks and manages changes to a set of files and resources. • You use version control all the time . -

It is a complex process to develop modern and professional software today. This document tries to give a brief overview of Software Development. This document tries to focus on a practical approach regarding Software Development. So why do we need System Engineering? Here are some key factors: • Understand Customer Requirements o What does the customer needs (because they may not know it!) o Transform Customer requirements into working software • Planning o How do we reach our goals? o Will we finish within deadline? o Resources o What can go wrong? • Implementation o What kind of platforms and architecture should be used? o Split your work into manageable pieces iii • Quality and Performance o Make sure the software fulfills the customers’ needs We will learn how to build good (i.e. high quality) software, which includes: • Requirements Specification • Technical Design • Good User Experience (UX) • Improved Code Quality and Implementation • Testing • System Documentation • User Documentation • etc. You will find additional resources on this web page: http://www.halvorsen.blog/documents/programming/software_engineering/ iv Information about the author: Hans-Petter Halvorsen The author currently works at the University of South-Eastern Norway. -
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. -
