Keyword substitution: kv
Default branch: MAIN

Changes 3.3.0:
- New things:
  - CAPI: GEOSBufferWithParams (allows single sided buffers)
  - CAPI: GEOSOffsetCurve deprecates GEOSSingleSidedBuffer
  - CAPI: GEOSUnaryUnion deprecates GEOSCascadedUnion
  - CAPI: GEOSisValidDetail: tell state, reason & location apart. allows
          passing flags.
  - CAPI: GEOSContext_setNoticeHandler_r, GEOSContext_setErrorHandler_r
  - CAPI: GEOSGeom_createEmptyPoint, GEOSGeom_createEmptyLineString
          GEOSGeom_createEmptyPolygon, GEOSGeom_createEmptyCollection
  - CAPI: GEOSGeom_extractUniquePoints
  - CAPI: GEOSGetGeometryN support for single geometries
  - CAPI: GEOSPolygonize_full to return all informations computed by
          the polygonizer
  - CAPI: GEOSOrientationIndex
  - CAPI: GEOSSharedPaths to find shared paths and their orientation
  - CAPI: GEOSSnap
  - CAPI: GEOSRelatePatternMatch
  - CAPI: GEOSCovers, GEOSCoveredBy
  - CAPI: GEOSRelateBoundaryNodeRule
  -  PHP: new PHP5 bindings based on CAPI
- Semantic C++ API changes:
  - Geometry inheritance chain changed to introduce Puntal, Lineal
    and Polygonal classes (virtual inheritance introduced)
  - Polygonizer::getInvalidRingLines retains ownership of vector elements
  - Geometry::isWithinDistance method is now const
  - Polygonizer::getCutEdges returns by const ref
  - Polygonizer::getDangles returns by const ref
  - Empty LinearRings are closed by definition
- Bug fixes / improvements
  - Fixed Geometry.distance() and DistanceOp to return 0.0 for empty inputs
  - Invalid compound geometries reported as valid
  - Return up to 15 digits of precision from GEOSisValidReason_t
  - CAPI: do not leak contexts when using the non-reentrant interface
  - Fix duplicated dangles returned by Polygonizer
  - Fix SnapIfNeededOverlayOp to throw the originating exception
  - Fixed LineMerger to skip lines with only a single unique coordinate
  - Fix NodedSegmentString to handle zero-length line segments correctly
    (via safeOctant)
  - Fixed buffer OffsetCurveSetBuilder to handle "flat" rings correctly
  - Added illegal state check in LineSegment::pointAlongOffset()
  - Improved performance of RectangleIntersects by always using
    segment-scanning and refining SegmentIntersectionTester
  - Reduce memory use in PreparedGeometry predicates
  - Fix infinite loop in RobustDeterminant with nan/inf input

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

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.

revbump due to geography/geos shlib major bump

bump required version (geos-config has a new option).
No PKGREVISION++ (riding upgrade < 1 hour ago).

Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.

Over 1200 files touched but no revisions bumped :)

RECOMMENDED is removed. It becomes ABI_DEPENDS.

BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.

BUILDLINK_DEPENDS does not change.

IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".

Added to obsolete.mk checking for IGNORE_RECOMMENDED.

I did not manually go through and fix any aesthetic tab/spacing issues.

I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.

I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.

As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.

As discussed on tech-pkg.

I will commit to revbump, pkglint, pkg_install, createbuildlink separately.

Note that if you use wip, it will fail!  I will commit to pkgsrc-wip
later (within day).

Import geos from pkgsrc-wip.  Packaged by David Price.

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().
