Version Control Systems, Build Automation and Continuous Integration Integration and Verification Techniques
Version Control Systems, Build Automation and Continuous Integration Integration and Verification Techniques Systematic methods and automation can highly enhance the teamwork on software projects. During this laboratory we will learn the basics of the following techniques: • Version control systems to support efficient teamwork. • Build automation to ensure stable and consistent builds. • Continuous Integration to provide automatic and systematic build, test execution and also deployments. 1 Version Control Systems Version control systems allow to keep all the historical versions of your software for easy tracking. Using version control also benefits team collaboration and improves the efficiency of the development team. In addition, it can be used as a central repository for the data, making build automation and continuous integration possible. There are historically two different approaches for managing the repositories: • Centralized model (CVS and Subversion/SVN): there is one server that contains “the repository” and everyone else checks code into and out of that repository. An important feature of these systems is that only the repository has the full history of all changes made. A checkout from this central repository will place a “working copy” on the user’s machine. This is a snapshot from a certain version of the project on his/her disk. • Distributed model (Git): In a distributed version control system, instead of a checkout, a user will clone a repository from a remote server. In return, he/she receives a full-fledged repository, not just a working copy. The user then has his/her own repository on the local machine – including all of the project’s history. -

Nys Fair Events Mobile Application with Client-Side Caching
NYS FAIR EVENTS MOBILE APPLICATION WITH CLIENT-SIDE CACHING A Master’s Project Presented to Department of Computer and Information Sciences SUNY Polytechnic Institute Utica, New York In Partial Fulfilment of the requirements for the Master of Science Degree By Sumant Kanala (U00287895) December 2017 © SUMANT KANALA 2017 NYS Fair Events Mobile application with client-side caching Declaration I declare that this project is my own work and has not been submitted in any form for another degree or diploma at any university or other institute of tertiary education. Information derived from the published and unpublished work of others has been acknowledged in the text and a list of references is given. _________________ Sumant Kanala Abstract NYS Fair Events collects data about fair events which happen in New York state throughout the year, bundles them, displays the upcoming events and useful information about the event itself, the weather and forecast prediction, and a Google Maps to show the route to the event from the user’s location. The motivation for creating this project arose with understanding the growing market for mobile applications and by working for a startup for several months now in the field of web development. A trend has been established in which more users are switching towards mobile apps as their preferred information exchange tool than their traditional PCs and hence the development of better apps should be geared towards mobile phones and tablet PCs. The development of the app is mainly divided into two steps, the client and server side. For the client side I developed a Cordova-based mobile app which is cross-platform and can be compiled to work on Android and IOS based mobile devices. -

Precise Null Pointer Analysis Through Global Value Numbering
Precise Null Pointer Analysis Through Global Value Numbering Ankush Das1 and Akash Lal2 1 Carnegie Mellon University, Pittsburgh, PA, USA 2 Microsoft Research, Bangalore, India Abstract. Precise analysis of pointer information plays an important role in many static analysis tools. The precision, however, must be bal- anced against the scalability of the analysis. This paper focusses on improving the precision of standard context and flow insensitive alias analysis algorithms at a low scalability cost. In particular, we present a semantics-preserving program transformation that drastically improves the precision of existing analyses when deciding if a pointer can alias Null. Our program transformation is based on Global Value Number- ing, a scheme inspired from compiler optimization literature. It allows even a flow-insensitive analysis to make use of branch conditions such as checking if a pointer is Null and gain precision. We perform experiments on real-world code and show that the transformation improves precision (in terms of the number of dereferences proved safe) from 86.56% to 98.05%, while incurring a small overhead in the running time. Keywords: Alias Analysis, Global Value Numbering, Static Single As- signment, Null Pointer Analysis 1 Introduction Detecting and eliminating null-pointer exceptions is an important step towards developing reliable systems. Static analysis tools that look for null-pointer ex- ceptions typically employ techniques based on alias analysis to detect possible aliasing between pointers. Two pointer-valued variables are said to alias if they hold the same memory location during runtime. Statically, aliasing can be de- cided in two ways: (a) may-alias [1], where two pointers are said to may-alias if they can point to the same memory location under some possible execution, and (b) must-alias [27], where two pointers are said to must-alias if they always point to the same memory location under all possible executions. -
