AW: [Qgis-developer] Planning for QGIS 1.0.0 '????'

[Hugentobler Marco]

Hi Jürgen,

I did some tests with the geos c-api patch and have the following comments:

- GEOSGeometry seems to be GEOSGeom in geos 2. Maybe version 2 could be supported by a typedef or define ?
- The tool to add rings to a polygon did not work when I tested it
- The same with the tool to add islands to selected polygons

I used geos 3.0.0 for the tests.

Thanks anyway for doing the port to c-api. I know it is a difficult task because many parts in qgis depend on geos functionality.

Regards,
Marco

Hi,

I posted the proposal[1] including a patch[2]. The QGIS patch is on [3].

QGIS patch summary:
- cmake now looks for the geos_c instead of the geos library
- QgsGeometry ported to GEOS C-API (needs geos patch [1])
- QgsSpatialIndex now catches (and ignores) exceptions
- removed (previously unused?) references to the GEOS geometry factory from
  QgsOgrProvider
- QgsWfsProvider now uses QgsSpatialIndex instead of GEOS spatial index.

Should this go to a separate branch or do I simply commit it to trunk?  I'd say
it's more likely that it gets the testing it needs in trunk...
