[geos-devel] GEOS Todo

[Ferdinando Villa]

the Boost library (www.boost.org) has a shared_ptr that sounds like a
good match for the precision model thing. The various boost smart
pointers can be taken from boost rather easily and incorporated - it's
all in template headers. It's got local and shared pointers for both
scalars and arrays, plus a zillion of other useful things.

This stuff tends to get tricky with multiple threads - are we
considering thread safety in GEOS? It's going to be important for some
applications (notably mine). Boost has good thread support.

Valgrind is great. I also have a license for Parasoft's insure++ ($$$)
that does a few more things (when it works) including coverage analysis
that helps greatly in optimization, and precise allocation mapping. I
can run GEOS test cases through it when I'm back to the office (Jun 20)
and post the leak and coverage reports.
