  • discuss on the dev mailing list or on irc.freenode.org #postgis
• if bug correction
  • create / update tickets
• if minor changes (no API break)
  • directly work on it
• in all case : create a branch with a telling name (what you will be working on)
• to code
  • start from SQL looking for the function definition and the associated C function
  • look for C function in postgis sources, and look if the postgis function calls a libgeom function
  • etc
• to test
  • if libgeom : CUnit
    • cd liblwgeom/cunit/
    • make check
  • test at the postgres level (before submitting the code)
    • make
    • make check
