    Analyzing dynamic information with spy and roassal: an experience report
    (2015) Alison Fernandez Blanco; Diego Gabriel Nunez Duran; Alejandro Infante; Alexandre Bergel
    Dynamic analyses tools are seldom crafted by practitioners. This paper discusses the benefits of supporting the practitioners to build their ad-hoc tool and presents our experience to lower the barrier to gather dynamic information. The experience we present is driven by the combination of the Spy profiling framework and the Roassal visualization engine, two frameworks used in industry and academia. We conclude with two question to discuss at the workshop.

    Effective Visualization of Object Allocation Sites
    (2018) Alison Fernandez Blanco; Juan Pablo Sandoval Alcocer; Alexandre Bergel
    Profiling the memory consumption of a software execution is usually carried out by characterizing calling-context trees. However, the plurality nature of this data-structure makes it difficult to adequately and efficiently exploit in practice. As a consequence, most of anomalies in memory footprints are addressed either manually or in an ad-hoc way. We propose an interactive visualization of the execution context related to object productions. Our visualization augments the traditional calling-context tree with visual cues to characterize object allocation sites.We performed a qualitative study involving eight software engineers conducting a software execution memory assessment. As a result, we found that participants find our visualization as beneficial to characterizing a memory consumption and to reducing the overall memory footprint.
