SWIG Language Bindings

General :

CSharp bindings:

  • Implement the typemap for utf8_path in C# (#3766)
  • Correcting the signature of OGRDataSource.Open to make the utf8 typemap to work (#3766)

Java bindings:

  • Turn the gdalJNI, gdalconstJNI and osrJNI into package private classes
  • Make Layer.GetExtent() return null when OGR_L_GetExtent() fails.

Perl bindings:

  • The "Points" method of Geometry was not accepting its own output in the case of a single point. It accepted only a point as a list. Now it accepts a point both as a list containing one point (a ref to a point as a list) and a point as a list.
  • Fixed UTF-8 support in decoding names (datasource, layer, field etc.).
  • Assume all GDAL strings are UTF-8, handle all changes in typemaps.
  • Additions to Perl bindings due to new developments etc: Layer capabilities, GeometryType method for Layer, improved create, new Export and Set methods for SpatialReference.
  • Detect context in a typemap which returns a array, this now returns a list in list context; the change affects at least GetExtent and GetEnvelope methods, which retain backward compatibility though new and/or changed methods: FeatureDefn::Name, FeatureDefn::GeometryIgnored, FeatureDefn::StyleIgnored, Feature::ReferenceGeometry, Feature::SetFrom, FieldDefn::Ignored, Geometry::AsJSON
  • Perl typemaps: more correct manipulation of the stack, more cases where a list is returned in a list context, better handling of callback_data @Band::COLORINTERPRETATIONS, Band methods Unit, ScaleAndOffset, GetBandNumber, RasterAttributeTable method LinearBinning
  • Typemaps for VSIF{Write|Read}L, tests and docs for some VSI* functions.
  • Perl bindings: better by name / by index logics, some checks for silent failures, return schema as a hash if wanted, support ->{field} syntax for features, return list attributes as lists or listrefs as wished so that ->{field} works for lists too (API change)

Python bindings:

  • Improvements for ogr.Feature field get/set
  • Add hack to bring Python 3.2 compatibility
  • First argument of VSIFWriteL() should accept buffers for Python3 compat
  • Fix reference leak in 'typemap(in) char dict'
  • Add gdal.VSIStatL()
  • swig/python/ : fix for virtualenv setups (#4285)
  • Layer.GetExtent() : add optional parameter can_return_null that can be set to allow returning None when OGR_L_GetExtent() fails
  • Make gdal.VSIFSeekL(), gdal.VSIFTellL() and gdal.VSIFTruncateL() use GIntBig instead of long for compat with 32bit platforms
  • Add script to build the python extensions with Python 2.7 and a mingw32 cross-compiler under Linux/Unix

Ruby bindings:

  • Build SWIG Ruby Bindings against modern Ruby versions (1.8.7 and 1.9.2) (#3999)
