I have adapted the existent patch to the new benchmarks codebase. Please see the new patch (django_v3_2.patch) in the files section. The benchmark expects to have django in lib/Django-1.9 folder. The Django-1.9 sources are attached separately because of their size.

hg clone https://hg.python.org/benchmarks
cd benchmarks/
copy django_v3_2.patch to the current directory and Django-1.9.tar.gz to the lib/ directory
hg import --no-commit django_v3_2.patch
cd lib/
tar -xvf Django-1.9.tar.gz
