When the pressure is on to resolve an elusive software or hardware glitch, what’s needed is a cool head courtesy of a set of rules guaranteed to work on any system, in any circumstance. Written in a frank but engaging style, this book provides simple, foolproof principles guaranteed to help find any bug quickly. Recognized tech expert and author David Agans changes the way you think about debugging, making those pesky problems suddenly much easier to find and fix. Agans identifies nine simple, practical rules that are applicable to any software application or hardware system, which can help detect any bug, no matter how tricky or obscure. Illustrating the rules with real-life bug-detection war stories, Debugging shows you how to: Understand the system: how perceiving the ""roadmap"" can hasten your journey Quit thinking and look: when hands-on investigation can’t be avoided Isolate critical factors: why changing one element at a time can be an essential tool Keep an audit trail: how keeping a record of the debugging process can win the day Whether the system or program you’re working on has been designed wrong, built wrong, or used wrong, Debugging helps you think correctly about bugs, so the problems virtually reveal themselves.

The book teaches How to Approach Software Debugging As a Reproducible Science. Noting in life is certain except death, taxes, and software bugs. Effective debugging involves for more than walking through code with a debugger. This book recognized this and teaches a mindset that allows you to reliably find and fix bugs. It sets out to make debugging less baffling, faster, and more effective by providing you with the knowledge and techniques needed to rapidly identify, track down, and repair bugs. It goes further by offering practical tips on minimizing bugs and making them easier to find when they do occur.

Debugging is crucial to successful software development, but even many experienced programmers find it challenging. Sophisticated debugging tools are available, yet it may be difficult to determine which features are useful in which situations. The Art of Debugging is your guide to making the debugging process more efficient and effective. The Art of Debugging illustrates the use three of the most popular debugging tools on Linux/Unix platforms: GDB, DDD, and Eclipse. The text-command based GDB (the GNU Project Debugger) is included with most distributions. DDD is a popular GUI front end for GDB, while Eclipse provides a complete integrated development environment. In addition to offering specific advice for debugging with each tool, authors Norm Matloff and Pete Salzman cover general strategies for improving the process of finding and fixing coding errors, including how to: –Inspect variables and data structures –Understand segmentation faults and core dumps –Know why your program crashes or throws exceptions –Use features like catchpoints, convenience variables, and artificial arrays –Avoid common debugging pitfalls Real world examples of coding errors help to clarify the authors’ guiding principles, and coverage of complex topics like thread, client-server, GUI, and parallel programming debugging will make you even more proficient. You'll also learn how to prevent errors in the first place with text editors, compilers, error reporting, and static code checkers. Whether you dread the thought of debugging your programs or simply want to improve your current debugging efforts, you'll find a valuable ally in The Art of Debugging.

This book is part of aaThe Minimum You Need to Knowaa family of books by Logikal Solutions. As the family expands they will cover an increasing variety of topics. This book is designed to be used as a text book for classes in logic from high school to college level. It should be one of the first courses you have on IT and this should be one of the first books you read when starting in IT. Not only does this book cover flow charting and pseudocode, it teaches the reader to think before they start mapping out the logic to solve a problem. The author of this book is an industry veteran with nearly 20 years in the field. It has been his experience that recent graduates, from any country, are nearly useless at problem solving. If they cannot point, click, and drag, they cannot solve the problem. This book is an attempt to teach them how to solve the problem. An instructoraas guide is available for schools looking to make this book the basis of coursework.

Software bugs hurt software reliability, and software companies are spending a huge amount of effort on finding and fixing bugs. Among all types of software bugs, concurrency bugs are among the most troublesome. Concurrency bugs have caused real-world disasters and are increasingly becoming an issue in this multi-core era. Lots of research efforts have been spent on concurrency bugs with a focus on bug finding. This thesis works on two directions to provide comprehensive tool support for concurrency bugs, complementing existing work on bug finding: production-run failure diagnosis for multi-threaded software and automated concurrency-bug fixing. Production-run failure diagnosis tools help programmers understand these bugs that are missed by various bug-finding tools and manifest at user sites. Despite all the efforts on concurrency bugs, software companies still release software that contains concurrency bugs, and they would manifest during production runs. To help understand the concurrency bugs behind these failures, we design and implement Cooperative Concurrency bug Isolation (CCI). CCI follows the high-level strategy of predicate sampling and statistical debugging approach. We design different predicate schemes that are highly related with thread interaction abnormalities to help explain failures caused by concurrency bugs. For each predicate scheme, we design a suitable sampling strategy so that the overhead would be low enough for production environment. CCI leverages existing statistical debugging techniques to process data collected by the sampled predicates. Evaluation suggests that CCI is capable of diagnosing many real-world concurrency bugs with low run-time overhead. Automated bug fixing tools speed up the bug fixing process. Our automated concurrency-bug fixing tool, CFix, builds on the observation that concurrency bugs can be fixed by removing buggy interleavings, and leverages recent advances on bug finding tools to report buggy interleavings. CFix includes several components on static synchronization enforcement, software testing, and patch optimization to automate the whole process of concurrency-bug fixing. Evaluation shows that CFix is able to generate patches that are comparable with manual patches regarding correctness, performance, and simplicity. With CCI and CFix, we envision a self-healing system for multi-threaded software.
