Enforcing Abstract Immutability written by Jonathan Eyolfson and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2018 with categories.
Researchers have recently proposed a number of systems for expressing, verifying, and inferring immutability declarations. These systems are often rigid, and do not support "abstract immutability". An abstractly immutable object is an object o which is immutable from the point of view of any external methods. The C++ programming language is not rigid-it allows developers to express intent by adding immutability declarations to methods. Abstract immutability allows for performance improvements such as caching, even in the presence of writes to object fields. This dissertation presents a system to enforce abstract immutability. First, we explore abstract immutability in real-world systems. We found that developers often incorrectly use abstract immutability, perhaps because no programming language helps developers correctly implement abstract immutability. We believe that this omission leads to incorrect usages. Specifically, we wrote a dynamic analysis that reports any writes through immutability declarations. To our knowledge, this work was the first to explore how objects implement abstract immutability (or fail to implement it). Our novel study found three uses of abstract immutability: caching, delayed initialization, and unit testing. Unit testing was a surprising application of abstract immutability, and we believe that the ability to modify state is needed for proper unit testing. Next, we explore developers' revealed needs for immutability in the source code. We found that the majority of classes contain a mix of immutable and mutable methods, with a majority of the overall methods being immutable. Immutability systems with only immutable or all-mutating classes are insufficient: developers need immutability declarations at method granularity. Our study then combined developer immutability declarations with results from a static analysis to estimate the true number of immutable methods. The static analysis checked that no transitive writes to a receiver object occurred. Our results indicated the need for a sophisticated analysis to check that these apparently abstractly immutable methods were indeed abstractly immutable. Finally, we created a novel static analysis which checks that developers follow abstract immutability. Specifically, we define abstract immutability to mean that a class's set of immutable methods is collectively free of writes to exposed fields. Our analysis found incorrect usages of abstract immutability, such as incorrect caching. This analysis is particularly valuable in the context of code evolution, whereby subsequent programmers may make changes that break previously-correct cache implementations, for instance. Our work allows developers to trust that their code is abstractly immutable.

I have been on a long spiritual journey studying Christian theology. Overtime, it became abundantly oblivious to me that if the Christian faith is really true, it is not being given the weight suggested by what we profess to believe. There are aspects of what we profess to believe that are very comforting, the Love of God for one. There are aspects of Christianity that are hard to understand, Hell as another example. These two aspects of our faith coexist in the immutable nature of God. Neither of these aspects of God's nature can ever be diminished or compromised. Since God cannot compromise His intrinsic nature, these truths give rise to our need for a all sufficient Savior. This book is exploring the wonders of God's salvific work to bring sinners into a right standing with our Heavenly Father.

This book teaches you how to evaluate a distributed system from the perspective of immutable objects. You will understand the problems in existing designs, know how to make small modifications to correct those problems, and learn to apply the principles of immutable architecture to your tools. Most software components focus on the state of objects. They store the current state of a row in a relational database. They track changes to state over time, making several basic assumptions: there is a single latest version of each object, the state of an object changes sequentially, and a system of record exists. This is a challenge when it comes to building distributed systems. Whether dealing with autonomous microservices or disconnected mobile apps, many of the problems we try to solve come down to synchronizing an ever-changing state between isolated components. Distributed systems would be a lot easier to build if objects could not change. After reading The Art of Immutable Architecture, you will come away with an understanding of the benefits of using immutable objects in your own distributed systems. You will learn a set of rules for identifying and exchanging immutable objects, and see a collection of useful theorems that emerges and ensures that the distributed systems you build are eventually consistent. Using patterns, you will find where the truth converges, see how changes are associative, rather than sequential, and come to feel comfortable understanding that there is no longer a single source of truth. Practical hands-on examples reinforce how to build software using the described patterns, techniques, and tools. By the end of the book, you will possess the language and resources needed to analyze and construct distributed systems with confidence. The assumptions of the past were sufficient for building single-user, single-computer systems. But aswe expand to multiple devices, shared experiences, and cloud computing, they work against us. It is time for a new set of assumptions. Start with immutable objects, and build better distributed systems. What You Will Learn Evaluate a distributed system from the perspective of immutable objects Recognize the problems in existing designs, and make small modifications to correct them Start a new system from scratch, applying patterns Apply the principles of immutable architecture to your tools, including SQL databases, message queues, and the network protocols that you already use Discover new tools that natively apply these principles Who This Book Is For Software architects and senior developers. It contains examples in SQL and languages such as JavaScript and C#. Past experience with distributed computing, data modeling, or business analysis is helpful.
