摘要： A novel system, computer program product, and method are disclosed for transforming a program to facilitate points-to analysis. The method begins with accessing at least a portion of program code, such as JavaScript. In one example, a method with at least one dynamic property correlation is identified for extraction. When a method m is identified for extraction with the dynamic property correlation, a body of the loop l in the method m is extracted. A new method mp is created to include the body of the loop l with the variable i as a parameter. The loop l is substituted in the program code of the method m with the new method mp to create a transformed program code.

摘要： Automated refactorings as implemented in modern IDEs for Java usually make no special provisions for concurrent code. Thus, refactored programs may exhibit unexpected new concurrent behaviors. We analyze the types of such behavioral changes caused by current refactoring engines and develop techniques to make them behavior-preserving, ranging from simple techniques to deal with concurrency-related language constructs to a framework that computes and tracks synchronization dependencies. By basing our development directly on the Java Memory Model we can state and prove precise correctness results about refactoring concurrent programs. We show that a broad range of refactorings are not influenced by concurrency at all, whereas other important refactorings can be made behavior-preserving for correctly synchronized programs by using our framework. Experience with a prototype implementation shows that our techniques are easy to implement and require only minimal changes to existing refactoring engines.
摘要翻译：在Java的现代IDE中实现的自动重组通常对并发代码没有特别规定。因此，重构的程序可能会出现意想不到的新并发行为。我们分析由当前重构引擎引起的这种行为变化的类型，并开发技术以使其保持行为，从简单技术到处理与并发相关的语言结构到计算和跟踪同步依赖关系的框架。通过将我们的开发直接基于Java内存模型，我们可以声明并证明重构并发程序的精确的正确性结果。我们表明，广泛的重构不受并发影响，而其他重要的重构可以通过使用我们的框架来进行正确同步的程序的行为保留。使用原型实现的经验表明，我们的技术易于实现，并且只需要对现有重构引擎进行最小的更改。

摘要： Disclosed is a novel computer implemented system, on demand service, computer program product and a method that provides a set of lock usages that improves concurrency resulting in execution performance of the software application by reducing lock contention through refactoring. More specifically, disclosed is a method to refactor a software application. The method starts with accessing at least a portion of a software application that can execute in an operating environment where there are more two or more threads of execution. Next, a determination is made if there is at least one lock used in the software application to enforce limits on accessing a resource. In response to determining that there is a lock with a first type of construct with a given set of features, the software application is refactored with the lock to preserve behavior of the software application.

摘要： A novel system, computer program product, and method are disclosed for feedback-directed automated test generation for programs, such as JavaScript, in which execution is monitored to collect information that directs the test generator towards inputs that yield increased coverage. Several instantiations of the framework are implemented, corresponding to variations on feedback-directed random testing, in a tool called Artemis.
