R.Dubois Science Tools Development Infrastructure 2/7 GLAST LAT ProjectSoftware Workshop July, SLAC What are we trying to build? Current model: –C++ - based atomic tools that can be chained together –Typically a collection of main routines that perform specific functions Parameters obtained from IRAF files I/O by FITS files Required components –File repository –Code management system –Code documentation tool –Collection of external libraries IRAF, FITS, plotting packages –Machinery to build and test releases

R.Dubois Science Tools Development Infrastructure 3/7 GLAST LAT ProjectSoftware Workshop July, SLAC Software Development Approach Reuse much of LAT’s infrastructure Enable distributed development via cvs repository CMT tool permits equal development on Windows and Linux documentation and coding reviews enforce coding rules “Continuous integration” –Eliminate surprises for incoming code releases –Build code every night; alert owners to failures in build or running of unit tests. Results tracked in database. –Developing comprehensive system tests in multiple source configurations. Track results in database; web viewable.

R.Dubois Science Tools Development Infrastructure 7/7 GLAST LAT ProjectSoftware Workshop July, SLAC Outlook Machinery is in place for code development We do not yet have the habit of frequent tagging and declarations of releases No idea on System Tests yet!
