Description
When running gis_tests.gdal_tests.test_raster.GDALBandTests
tests on OSX 10.11.6 django calls capi.open_ds
inside GDALRaster
. This results in a Segmentation fault. Occurs on the master branch (80e742d991b276023a3aa51a29ed757879051282).

Even if we don't ship C code, either our documentation lacks some details on supported GDAL / GIS versions (that's beyond my knowledge) or we should check for that. Either way, I don't think Django's test should segfault regardless.

What are the installed GIS library versions? Did you reproduce the issue, Markus?
comment:5 by , 8 years ago
I can still reproduce it on master (24c9cce1c9fb0dfe14e42de1ec2a2a209a64dd80).
OSX 10.11.6
Library versions (installed from Homebrew):
gdal 1.11.5_1 geos 3.5.0 libgeotiff 1.4.1_2 liblwgeom 2.1.5_3 libtiff 4.0.6_2

The problem seems to be due to the way Pillow and GDAL interact. Pillow wheel ships its own version of libtiff while GDAL library uses the system one. This apparently causes the segfault. I don't have the skills to narrow it down further.
Workaround is to install Pillow from source on OSX:
pip install --no-binary Pillow -r tests/requirements/py3.txt

Look at this example. Install only pillow and Django without GDAL python binding. This code raise exeption after pillow installed.
GEOTIF_PATH=/ta/dem.tif virtualenv --python=python3 test cd test source bin/activate pip install django==1.11.9 pillow python -c "from django.contrib.gis.gdal import GDALRaster; print(GDALRaster('$GEOTIF_PATH'))" django-admin startproject testtest cd testtest django-admin startapp testtesttest echo "\n\nINSTALLED_APPS += ['testtesttest']" >> testtest/settings.py mkdir -p testtesttest/management/commands touch testtesttest/management/__init__.py testtesttest/management/commands/__init__.py echo "from django.core.management.base import BaseCommand class Command(BaseCommand): def handle(self, *args, **options): from django.contrib.gis.gdal import GDALRaster print(GDALRaster('$GEOTIF_PATH')) " > testtesttest/management/commands/gdal_test.py python manage.py gdal_test pip uninstall -y pillow python manage.py gdal_test
Result:
TIFFReadDirectory: Warning, Unknown field with tag 42113 (0xa481) encountered. [1] 53998 bus error python manage.py gdal_test

Django 1.11 and GDAL 1.11 are no longer supported. Closing unless someone can provide a clear path to reproduce this issue on supported versions.

Do you have any details about why Django might be at fault? We don't ship any C code, so segfaults are generally not caused by Django.
