[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 3.2.0, Package name: geos-3.2.0, Maintainer: gdt

GEOS (Geometry Engine - Open Source) is a C++ port of the Java
Topology Suite (JTS). It contain the complete functionality of JTS in
C++. It includes all the OpenGIS "Simple Features for SQL" spatial
predicate functions and spatial operators,and JTS topology functions
like IsValid().

Log message:
ABI incompatible change in 3.2.0, although perhaps only due to shlib
version matching release version.

Update to 3.2.0:

Changes in 3.2.0

- Add Single-sided buffer operation
- JTS-1.10 sync ...
  - Drastically improved Buffer speed (20x for a case in testsuite)
  - Improved EdgeList duplicate edge finding
  - Added algorithm::distance package
  - Added algorithm::Angle class
  - Added algorithm::BoundaryNodeRule class
  - IsSimpleOp can now return non-simple location coordinate
  - DistanceOp can now check for 'within distance' predicate
    (earlier exit)
  - MultiPolygon::getBoundary always return MultiLineString, also
    when the result is the EMPTY geometry.
- Various bug and leak fixes, optimizations
- Replace MarkupSTL with tinyXML

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
