SERG Reverse Engineering (REportal) REportal: Reverse Engineering Portal (reportal.cs.drexel.edu) SERG Reverse Engineering (REportal) Introduction Software Engineering community has produced many tools. Challenges: Usability Ease of Installation Interoperability Copyrighted works (limited distribution) DMCA (United States) SERG Reverse Engineering (REportal) Introduction Contd Weve faced these challenges with our own tools: CIAO Acacia (C/C++ Analysis) Chava (Java Analysis) Bunch (static clustering) Form (dynamic analysis) Graphviz (graph visualization) SERG Reverse Engineering (REportal) Background: Tools Source code analysis: Visual Studio, CIAO, Design Extraction: Bunch, Rigi, ARCH, Visualization: Graphviz, Rigi, Tom Sawyer, SERG Reverse Engineering (REportal) Standardization Attempts Difficulttools address different needs Not all tools are portable to all platforms Java is write once debug many times (http://www.lionhrtpub.com/orms/orms-2-99/cyberspace.html)http://www.lionhrtpub.com/orms/orms-2-99/cyberspace.html Not all interfaces are fully exposed Our proposed solution: REportal SERG Reverse Engineering (REportal) Login to REportal SERG Reverse Engineering (REportal) REportal Services Source code: Repository Analysis Querying Browsing Clustering Visualization SERG Reverse Engineering (REportal) REportals RE Process SERG Reverse Engineering (REportal) Using REportal 1.Create a new project 2.Upload source code 3.Open the project 4.Perform analysis on the code In this example, a software engineer needs to modify the addFilter() method in a software package, Form. SERG Reverse Engineering (REportal) Create Project SERG Reverse Engineering (REportal) Upload Code SERG Reverse Engineering (REportal) Open Project SERG Reverse Engineering (REportal) Entity Query SERG Reverse Engineering (REportal) Relationship Query SERG Reverse Engineering (REportal) Code Browsing SERG Reverse Engineering (REportal) Reachability Query SERG Reverse Engineering (REportal) Reachability Query II SERG Reverse Engineering (REportal) Module Dependency Graph SERG Reverse Engineering (REportal) Clustering SERG Reverse Engineering (REportal) Text Search SERG Reverse Engineering (REportal) REportal Architecture n-tiered Java servlet SERG Reverse Engineering (REportal) Extensibility Adding a tool is a two-stage process: 1.Tool is added to the servers tool set 2.Servlet is extended to include the tool among its set of services In the future, this process may be automated via a wizard-like facility SERG Reverse Engineering (REportal) Future Work Integrate more reverse-engineering tools into REportal Integrate dynamic analysis Security architecture Sandbox for running user Makefiles and applications C/C++ support Distributed/multi-platform support REportal distribution for remote site use SERG Reverse Engineering (REportal) Conclusions Advantages RE services provided via consistent web-based user interface No need to be aware of platform integration or interoperability issues Latest versions of underlying tools always available No software installs needed SERG Reverse Engineering (REportal) REportal Web Site
