Fiona 1.8.21 breaks GDAL/PROJ environment in Docker/Virtualenv

Hello,

Installing Fiona 1.8.21 breaks my GDAL/Proj environment in my docker image, with Python 3.7 running on Debian:buster-slim. However, rolling back to 1.8.20 with the exact same Dockerfile makes it work again.

I have several different errors like:

• fiona._err.CPLE_AppDefinedError: PROJ: proj_create: no database context specified
• fiona._err.CPLE_AppDefinedError: Cannot import GDLIB:32701 due to ALLOW_FILE_ACCESS=NO
• PROJCS["WGS 84 / UTM zone 40N",GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",57],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AXIS["Easting",EAST],AXIS["Northing",NORTH],AUTHORITY["EPSG","32640"]] != epsg:4326

Did you changed the gdal_data directory of Fiona ?

Here are the way I export my GDAL environment variables:

ENV CPLUS_INCLUDE_PATH="/usr/include/gdal"
ENV C_INCLUDE_PATH="/usr/include/gdal"
ENV PROJ_LIB="/usr/local/lib/python3.7/dist-packages/pyproj/proj_dir/share/proj"
ENV GDAL_DATA="/usr/local/lib/python3.7/dist-packages/fiona/gdal_data/"

@remi-braun is your intention to have rasterio and fiona use the same GDAL apt package? In that case, eliminate pip install --no-cache-dir --global-option=build_ext --global-option="-I/usr/include/gdal" GDAL=='gdal-config --version' and replace with pip install --no-binary fiona,rasterio fiona rasterio. Fiona and rasterio don’t depend on the GDAL Python package. Then you can unset PROJ_LIB and GDAL_DATA.

The GDAL and PROJ data files included in the fiona and rasterio wheels are intended for use with that installed package only. They can’t reliably be shared with other applications on your system.

I have the same issue with reading GML files, but not with a ESRI Shapefile with a prj file. Is this an issue that GDAL tries to read files not related directly to the sourcefile? The 28992 is the EPSG code for the Dutch Rijksdriehoek coordinate system.
