[gdal-dev] How to set OGR_INTERLEAVED_READING when using the OSM driver

[Paolo Corti]

Hi guys

I am giving a try to the new OSM driver, that looks very promising to me ;)
I am using the latest source code from trunk, and I cannot figure out
how can I set the OGR_INTERLEAVED_READING when using ogr2ogr.

If I try to export an OSM file like this the option seems to be
ignored, and the process export just the first 100k features:

$ ogr2ogr test.shp myfile.pbf lines -lco OGR_INTERLEAVED_READING=YES
ERROR 1: Too many features have accumulated in lines layer. Use
OGR_INTERLEAVED_READING=YES mode

If I try to export the OGR_INTERLEAVED_READING as an env variable, the
process fails:

$ export OGR_INTERLEAVED_READING=YES

$ ogr2ogr test.shp myfile.pbf lines --debug ON
OGR: OGROpen(myfile.pbf/0x914ef78) succeeded as OSM.
Shape: DBF Codepage = LDID/87 for test.shp
Shape: Treating as encoding 'ISO-8859-1'.
OSM: OGR_INTERLEAVED_READING = 1
OSM: Got bounds : minx=11.361760, miny=40.717850, maxx=14.099890, maxy=42.916190
OSM: For layer points, new max size is 128

OSM: For layer points, new max size is 608

OSM: For layer points, new max size is 14505
OSM: For layer points, new max size is 21885
OSM: For layer points, new max size is 32955
OSM: For layer points, new max size is 49560
OSM: Switching to 'points' as they are no more feature in 'lines'
OGR2OGR: 0 features written in layer 'test'
OSM: Number of bytes read in file : 14874118

According to the documentation anyway, the option should not be set at
all, as "the ogr2ogr application has been modified to use that
OGR_INTERLEAVED_READING mode without any particular user action".

Ideas? Am I doing something obviously wrong?
thanks
