This thesis introduced a tool CoRec which can provide co-change suggestions when JavaScript programmers fix a bug. A comprehensive empirical study was carried out on 14,747 multi-entity bug fixes in ten open-source JavaScript programs. We characterized the relationship between co-changed entities (e.g., functions and variables), and extracted the most popular change patterns, based on which we built a machine learning (ML)-based approach to recommend additional entity to edit given developers’ code changes. Our empirical study shows that: (1) 50% of the crawled commits involve multi-entity edits (i.e., edits that touch multiple entities simultaneously); (2) three change patterns commonly exist in all ten projects; (3) 80-90% of co-changed function pairs in the 3 patterns either invoke the same function(s), access the same variable(s), or contain similar statement(s); and (4) our ML-based approach CoRec recommended entity changes with high accuracy. Our research will improve programmer productivity and software quality.

Повний текст джерелаIn this thesis, we address the issue of enforcing confidentiality and integrity policies in the context of client-side Web applications. Since most Web applications are developed in the JavaScript programming language, we study static, dynamic, and hybrid enforcement mechanisms for securing information flow in Core JavaScript --- a fragment of JavaScript that retains its defining features. Specifically, we propose: a monitored semantics for dynamically enforcing secure information flow in Core JavaScript as well as a source-to-source transformation that inlines the proposed monitor, a type system that statically checks whether or not a program abides by a given information flow policy, and a hybrid type system that combines static and dynamic analyses in order to accept more secure programs than its fully static counterpart. Most JavaScript programs are designed to be executed in a browser in the context of a Web page. These programs often interact with the Web page in which they are included via a large number of external APIs provided by the browser. The execution of these APIs usually takes place outside the perimeter of the language. Hence, any realistic analysis of client-side JavaScript must take into account possible interactions with external APIs. To this end, we present a general methodology for extending security monitors to take into account the possible invocation of arbitrary APIs and we apply this methodology to a representative fragment of the DOM Core Level 1 API that captures DOM-specific information flows

Повний текст джерелаMålet med denna undersökning har varit att besvara frågorna ”vilka grafer kan användas för att visa en speciell typ av information?”,”vilken information be- höver ett företag veta för att fastslå att en server är nere?” samt ”hur ska det utvecklade systemet vara upplagt för att vara enkelt att förstå samt trevligt att använda?”. Undersökningen har utförts med hjälp av användarintervjuer samt information som insamlats under möten. Utöver denna information så har också en prototyp av en så kallad ”dashboard” skapats där grafer samt funktioner som föreslagits undersökts för att återge om informationen samt funktionerna på gränssnittet visas på ett bra sätt. Denna information har då sammanställts till ett resultat som visar att det är viktigt att återvisa information över tid som gra- fer samt procentuell information med hjälp av en fyllande graf, då kanske en hastighetsmätargraf. Den andra frågan svarades enkelt på med hjälp av ett frågeformulär. Detta gav då som resultat att det var viktigt att se resursanvänd- ning på servrarna samt hur mycket information som skickas och mottages. Det- ta implementerades sedan i systemet. I de tidigare nämnda intervjuerna fram- kom det också att det var bra om systemet inte var ljust färgat då detta gjorde så att användarna blev enkelt distraherade av gränssnittet. På grund av detta så ändrades alla färger mot det mörkare spektrumet.

Modern web applications are distributed across a browser-based client and a remote server. Software developers need to optimize the performance of web applications as well as correct and modify their functionality. However, the vast majority of mature development tools, used for optimizing, correcting, and modifying applications work only with non-distributed software, written to run on a single machine. To facilitate the maintenance and evolution of web applications, this dissertation research contributes new automated software transformation techniques. These contributions can be incorporated into the design of software development tools, thereby advancing the engineering of web applications.

Due to the development and the popularity of Web applications, JavaScript is not only for assisting the display of items in websites but also be used for computation-intensive programs. The demand for higher performance JavaScript programs is growing. For decades, JavaScript engines have improved dramatically due to the introduced just-in-time (JIT) compilation techniques and some other optimizations. However, the nature of JavaScript language makes it difficult for further optimizations because its dynamic features make the program behavior unpredictable and hard to determine its type information at static time. In this thesis, we present an ahead-of-time JavaScript compiler, called JASM, which translates JavaScript programs into asm.js programs, which is a subset of the JavaScript language and has high-performance execution. subset of JavaScript and runs with high speeds. We also propose a data-flow-based type-inference system that infer all possible data types at static time. Our evaluations demonstrated that the proposed method is effective in improving the execution time of JavaScript programs in the test benchmarks on an average of 40x and 20x speedup on a PC and a mobile device, respectively.

JavaScript is a dynamic language that is widely supported in modern Web browsers.JavaScript programs are usually executed by a JavaScript engine, which is implemented using an interpreter or a just-in-time compiler. However, the dynamic aspects of interpretation and run-time compilation intrinsically limit the performance of JavaScript programs. In this paper, we propose a JavaScript compiler, called JSComp,that statically translates partial JavaScript programs into Native Client modules or asm.js programs for improving the execution performance and also a hybrid execution model (a combination of static compilation and dynamic interpretation) for JavaScript programs so as to take advantages of high-performance execution in the compilation model and dynamic code evaluation in the interpretation model. Our evaluations demonstrated that the proposed mechanisms were effective in improving the execution performance of JavaScript programs in the SunSpider benchmark suite by an average of 50%.

When developing a large software system, debugging is a very time-consuming process. As a result, Automatic Program Debug and Repair has become a hot research topic. In this thesis, we first review the Nopol system that can debug and repair Java programs, based on both the Test-Based Debug and Repair Model and the Single-Fault Model. Second, we revise Nopol to debug and repair JavaScript programs that are now popular in designing the front-end interface of web systems. Though Java and JavaScript share a lot of aspects, we point out that the latter one involves a lot of function calls that would cause a single-fault to become multiple faults that could not be debugged by the mechanism of Nopol. In addition, we propose a new mechanism to overcome this problem. Finally, we replace the brute-force patch generation process of Nopol with a new process that produces patches based on the special characteristics of JavaScript programs.

Повний текст джерелаUnderstanding of objects in object-oriented programs is an important task for understanding the code. JavaScript (JS) is a dynamic object-oriented language, Its dynamic nature makes understanding its source code very difficult. In this thesis, we focus on object analysis in JS programs to automatically produce a graph of objects inspired by UML class diagrams from an execution trace. The resulting graph shows the structure of the objects as well as their interconnections. Our approach uses a source-to-source transformation of the original code in order to collect information at runtime. This transformation makes it possible to collect complete information with respect to object creations and property updates. From this information, we perform multiple abstractions that aim to generate a more compact and intuitive representation of objects. This approach has been implemented in the JSTI prototype. To evaluate our approach, we measured its performance and the graph compression achieved by our abstractions. We used the ten V8 benchmarks for this purpose. Results show that JSTI is efficient enough to be used in practice, with an average slowdown of around 14x. Moreover, for 9 out of the 10 studied programs, the generated object graphs are sufficiently small to be visualized directly by developers. We have also performed a qualitative validation of the approach by manually inspecting the generated graphs. We have found that the graphs generated by JSTI generally correspond very closely to the expected results. Keywords: Program analysis, dynamic analysis, JavaScript, profiling.

Повний текст джерелаAsynchronous JavaScript and XML (AJAX) is the primary method for enabling asynchronous communication over the Web. Although AJAX is providing warranted real-time capabilities to the Web, it requires unconventional programming methods at the expense of extensive resource usage. WebSockets, which is an emerging protocol, has the potential to address many challenges with implementing asynchronous communication over the Web. There, however, has been no in-depth study that quantitatively compares AJAX and WebSockets. This thesis therefore provides two contributions to Web development. First, it provides an experience report for adding real-time monitoring support over the Web to the Open-source Architecture of Software Instrumentation of Systems(OASIS), which is open-source real-time instrumentation middleware for distributed real-time and embedded (DRE) systems. Secondly, it quantitatively compares using AJAX and WebSockets to stream collected instrumentation data over the Web in real-time. Results from quantitative comparison between WebSockets and AJAX show that a WebSockets server consumes 50% less network bandwidth than an AJAX server; a WebSockets client consumes memory at constant rate, not at an increasing rate; and WebSockets can send up to 215.44% more data samples when consuming the same amount network bandwidth as AJAX.
