gRPC Python: Instructions for Local Development

Note: The compilation of the C files (make) requires GCC version 7. Maybe LLVM?

1. Git clone & init the project

git clone ...
git submodule update --init

2. Create & setup a virtual environment

python3.7 -m venv py37_native
source py37_native/bin/activate
pip install -r requirements.txt
pip install six==1.12.0 cython

3. Compile

make  # Compiles the C files (required the first time)
python tools/run_tests/run_tests.py -l python  --compiler python3.7 --build_only  # this is required on every change of cython files

3.1 Optionally, reset the sub-modules

git submodule foreach --recursive git clean -xfd
git submodule foreach --recursive git reset --hard
git submodule update --init --recursive
make clean
make build

4. Run the tests

GRPC_ENABLE_FORK_SUPPORT=0 python ./src/python/grpcio_tests/setup.py test_aio

Running tests with Bazel

./tools/bazel test //src/python/grpcio_tests/tests_aio/...

5. Linting & sanity checks

bash ./tools/distrib/yapf_code.sh
bash ./tools/distrib/pylint_code.sh
bash ./tools/distrib/check_pytype.sh
bash ./tools/distrib/buildifier_format_code.sh
