Instead of 'loader.debug_type', introduce 'loader.log_level' and 'loader.log_file', along with a set of definitions for logging at a chosen level. For now, the call sites keep using the legacy macros (SGX_DBG and debug()), because converting them all will conflict with other big changes in the code base. The existing LibOS calls are assumed to be at 'info' level.
Python example
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 scripts/helloworld.py
./pal_loader ./python scripts/fibonacci.py
With SGX:
SGX=1 ./pal_loader ./python scripts/helloworld.py
SGX=1 ./pal_loader ./python scripts/fibonacci.py
You can also manually run included tests:
SGX=1 ./run-tests.sh
