    Avoiding infinite recursion with stratified aspects
    (NODe 2006 – GSEM 2006, 2006) Bodden, Eric; Forster, Florian; Steimann, Friedrich
    Infinite recursion is a known problem of aspect-oriented programming with AspectJ: if no special precautions are taken, aspects advising aspects can easily and unintentionally advise themselves. We present a compiler for an extension of the AspectJ programming language that avoids self reference by associating aspects with levels, and by automatically restricting the scope of pointcuts used by an aspect to join points of lower levels. We report on a case study using our language extension, and provide numbers of the changes necessary for migrating existing applications to it. Our results suggest that we can make programming with AspectJ simpler and safer, without restricting its expressive power unduly.

    Design and implementation of a backward-in-time debugger
    (NODe 2006 – GSEM 2006, 2006) Hofer, Christoph; Denker, Marcus; Ducasse, Stéphane
    Traditional debugging and stepping execution trace are well-accepted techniques to understand deep internals about a program. However in many cases navigating the stack trace is not enough to find bugs, since the cause of a bug is often not in the stack trace anymore and old state is lost, so out of reach from the debugger. In this paper, we present the design and implementation of a backward-in-time debugger for a dynamic language, i.e., a debugger that allows one to navigate back the history of the application. We present the design and implementation of a backward-in-time debugger called UNSTUCK and show our solution to key implementation challenges.

    Ds_Grid: A database oriented data grid supporting dynamicdata integration in a domain
    (NODe 2006 – GSEM 2006, 2006) Shen, Derong; Yu Ge; Wang, Guangqi; Li, Meifang
    Database oriented data grid becomes a new demand with the development of grid technology, and DS_Grid (DatabaSe oriented Data Grid) is such a grid system supporting dynamic data integration with the idea of service. In DS_Grid, MultiChord is adopted as the grid framework implementing the distributed storage, processing and data integration of data service resources and the domain and its corresponding data resources schema are specified according to text similarity definition to locate the peers data service resources registered, so as to improve the cover range of data service resources discovered, multi-root and multi-peer data resources replica management mechanism to improve the efficiency of discovering data service resources and the reliability and availability of DS_Grid, filter distributed data integration strategy is applied to reduce the traffic cost and the data integration cost, and distributed clustering analysis technology is realized to summarize the huge data information. The experiments have demonstrated the availability of the key technologies adopted in DS_Grid.
