Mark Cave-Ayland	ffde636dc0	Split the basic geometry accessors into a separate static library liblwgeom.a; this potentially allows re-use of the liblwgeom functions from within PostGIS, or could be extended at a later date to include databases other than MySQL. This patch includes a change to the liblwgeom handler functions; instead of sprinkling init_pg_func()s around the source, I have changed the default liblwgeom handlers to make use of a callback to allow linked libraries to set their own handlers the first time any of them are called. I have also tidied up the parser API a little in liblwgeom.h, which means wktparse.h can be removed from all of the headers in the lwgeom/ directory, plus renamed wktunparse.c to lwgunparse.c to keep things similar to lwgparse.c. Finally, I renamed liblwgeom.c to lwutil.c to avoid confusion within the new interface. TODO: the liblwgeom Makefile has some gcc-specific options, but these can be fixed later - it seemed more important to make the warnings visible to developers. ... git-svn-id: http://svn.osgeo.org/postgis/trunk@2815 b70326c6-7e19-0410-871a-916f4a2858ee	2008-06-29 19:11:48 +00:00
Mark Cave-Ayland	1243c2d07f	Commit new PostGIS debugging infrastructure. These changes unify all the debug logging to use a new set of macros: LWDEBUG()/LWDEBUGF() for LWGEOM functions, and POSTGIS_DEBUG()/POSTGIS_DEBUGF() for PostgreSQL functions. To enable debugging, run configure with --enable-debug and then remake the entire project. If --enable-debug is omitted during configure, the above macros evaluate to (void)0, and hence should be removed by the compiler during optimisation. Also: contains minor warning cleanups and a fix for the ST_Dwithin SQL definition. ... git-svn-id: http://svn.osgeo.org/postgis/trunk@2797 b70326c6-7e19-0410-871a-916f4a2858ee	2008-05-31 09:56:44 +00:00
Mark Leslie	c40a30b516	Added typedefs and serialization/deserialization functionality for sql-mm defined curved geometry types. Added a point_in_polygon short-circuit for contains and within functions. ... git-svn-id: http://svn.osgeo.org/postgis/trunk@2532 b70326c6-7e19-0410-871a-916f4a2858ee	2006-12-01 22:16:44 +00:00
