[gdal-dev] RFC 46 GDAL/OGR unification adopted and commited

[Etienne Tourigny]

Hi Even, great work!

Quick testing was fine and revealed no errors.

I was able to compile it in QGIS master very easily. The only "issue" I
encountered was related to GDALRegisterAll() and OGRAllRegister()
registering all drivers (raster and vector), requiring to ignore the
vector-only drivers in the raster-only related code in QGIS.

May I suggest a change that would improve backwards-compatibility and avoid
unwanted issues? Perhaps these 2 functions should only register raster or
vector drivers (as in GDAL 1.x), instead of all drivers, and a new function
would register both raster and vector drivers. This would ensure old code
behaves as previously, and ensure that no extra drivers are loaded and
probed when only raster/vector drivers are needed.

Just to be clearer here is how I would see it:
GDALRegisterAll() -> registers raster drivers (those with
GDAL_DCAP_RASTER="YES")
OGRAllRegister() -> registers vector drivers (those with
GDAL_DCAP_VECTOR="YES")
GDALRegisterDrivers() -> registers all drivers

On the other habd, I imagine this may not be easy to implement and could
cause some confusion in the future. Also, probing optimization can instead
be achieved using GDALOpenEx() specifying raster vs.vector drivers.

cheers,
Etienne
