This directory contains an example for running Python 3 in Graphene, including the Makefile and a template for generating the manifest. The application is tested on Ubuntu 16.04 and Ubuntu 18.04, with both normal Linux and SGX platforms. The tested versions of Python are 3.5 and 3.6.

Generating the manifest

Installing prerequisites

For generating the manifest and running the test scripts, please run the following command to install the required utility packages (Ubuntu-specific):

sudo apt-get install libnss-mdns

Building for Linux

Run make (non-debug) or make DEBUG=1 (debug) in the directory.

Building for SGX

Run make SGX=1 (non-debug) or make SGX=1 DEBUG=1 (debug) in the directory.

Building with a local Python installation

By default, the make command creates the manifest for the Python binary from the system installation. If you have a local installation, you may create the manifest with the PYTHONPATH variable set accordingly. You can also specify a particular version of Python. For example:

make PYTHONPATH=<python install path> PYTHONVERSION=python3.6 SGX=1

By default, PYTHONPATH=/usr and PYTHONVERSION=python3.5.

Run Python with Graphene

Here's an example of running Python scripts under Graphene:

Without SGX:

./pal_loader python.manifest scripts/helloworld.py
./pal_loader python.manifest scripts/fibonacci.py

With SGX:

SGX=1 ./pal_loader python.manifest scripts/helloworld.py
SGX=1 ./pal_loader python.manifest scripts/fibonacci.py

You can also manually run included tests:

SGX=1 ./run-tests.sh
