1 Ideas for cooperative software development for future GGOS stations (FESG) Martin Ettl (FESG) 1

2 Scientific Software - Tendency to become complex and unstructured - Highly specialized for dedicated purposes (e.g. PhD) - Undocumented, unreadable, not maintainable code - Error-prone, not well tested, not optimized realizations - Written in different computer languages - 2

3 Scientific Software Calculates all solutions for the queens puzzle (of chess boards with sizes from 1x1 to 99x99) Osovlanski, Doron; Nissenbaum, Baruch: baruch.c.baruch.hint. In: Noll, Landon Curt; Cooper, Simon; Seebach, Peter; Broukhis, Leonid A.: The International Obfuscated C Code Contest. Winning entries th International Obfuscated C Code Contest. 2003, Download

5 Scientific software - Reduction to a few software languages - Style guide with coding layout and coding policies - A general way to use legacy code - Documentation generation - Automated code tests and inspections - Version control - Offering of tested, open source toolboxes 5

6 Continuous Integration as a supporting service static analysis nightly build unit tests doc generator beautifier run e-service 6

7 Continuous Integration as a supporting service C/C++ - Static program analysis (cppcheck) - Spell check of program and text files (codespell) - Extracting of development information (StatSVN) - Find non-reentrant functions in code (nsiqcppstyle) - Find security problems (flawfinder) - Detect common printf/scanf format errors (pscan) - Generate developer documentation (doxygen) - Detect redundant files in the repository (own development) e-service 7
