We prove that certain formulations of program synthesis and reachability are equivalent. Specifically, our constructive proof shows the reductions between the template-based synthesis problem, which generates a program in a pre-specified form, and the reachability problem, which decides the reachability of a program location. This establishes a link between the two research fields and allows for the transfer of techniques and results between them.
To demonstrate the equivalence, we develop a program repair prototype using reachability tools. We transform a buggy program and its required specification into a specific program containing a location reachable only when the original program can …

Solving The Search For Suitable Code: An Initial Implementation, Kathryn T. Stolee, Sebastian Elbaum
CSE Technical Reports
Searching for code is a common task among programmers, with the ultimate goal of finding and reusing code or getting ideas for implementation. While the process of searching for code - issuing a query and selecting a relevant match - is straightforward, several costs must be balanced, including the costs of specifying the query, examining the results to find desired code, and not finding a relevant result. For the popular syntactic searches the query cost is quite low, but the results are often vague or irrelevant, so the examination cost is high and matches may not be found. Semantic searches …

Refactoring Pipe-Like Mashups For End-User Programmers, Kathryn T. Stolee, Sebastian Elbaum
CSE Technical Reports
Mashups are becoming increasingly popular as end users are able to easily access, manipulate, and compose data from many web sources. We have observed, however, that mashups tend to suffer from deficiencies that propagate as mashups are reused. To address these deficiencies, we would like to bring some of the benefits of software engineering techniques to the end users creating these programs. In this work, we focus on identifying code smells indicative of the deficiencies we observed in web mashups programmed in the popular Yahoo! Pipes environment. Through an empirical study, we explore the impact of those smells on end-user …
