I'm experiencing a reproducible bug.
I create new 258x258 pixel datasets like this:
driver = gdal.GetDriverByName('GTiff')
handle, filename = mkstemp(dir=tmpdir,
prefix='dem-tools-hillup-data-render-', suffix='.tif')
ds = driver.Create(filename, width, height, 1, gdal.GDT_Float32)
I also open a number of datasets in the same process using gdal.Open() and warp
them together with gdal.ReprojectImage().
When I have created 1,020 new datasets / opened 2,041 total datasets, I get a
None back from driver.Create(). This number is stable, and appears unrelated to
the specific datasets that I'm creating. Datasets are being flushed and falling
out of scope, so I believe that they're correctly being closed when they
should. Do these numbers sound like known, hard internal limits to anyone?
I'm using the 1.6 Python bindings on Ubuntu 10.04 LTS.
