Development Environment Setup

You can set up your dev environment with:

git clone git@github.com:ethereum/eth-account.git
cd eth-account
virtualenv -p python3 venv
. venv/bin/activate
pip install -e .[dev]

To run the integration test cases, you need to install node and the custom cli tool as follows:

apt-get install -y nodejs  # As sudo
./tests/integration/ethers-cli/setup_node_v12.sh  # As sudo
cd tests/integration/ethers-cli
npm install -g .  # As sudo

Testing Setup

During development, you might like to have tests run on every file save.

Show flake8 errors on file change:

# Test flake8
when-changed -v -s -r -1 eth_account/ tests/ -c "clear; flake8 eth_account tests && echo 'flake8 success' || echo 'error'"

Run multi-process tests in one command, but without color:

# in the project root:
pytest --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1

Run in one thread, with color and desktop notifications:

cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on eth-account failed'" ../tests ../eth_account

Release setup

For Debian-like systems:

apt install pandoc

To release a new version:

make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion

The version format for this repo is {major}.{minor}.{patch} for stable, and {major}.{minor}.{patch}-{stage}.{devnum} for unstable (stage can be alpha or beta).

To issue the next version in line, specify which part to bump, like make release bump=minor or make release bump=devnum. This is typically done from the master branch, except when releasing a beta (in which case the beta is released from master, and the previous stable branch is released from said branch).

If you are in a beta version, make release bump=stage will switch to a stable.

To issue an unstable version when the current version is stable, specify the new version explicitly, like make release bump="--new-version 4.0.0-alpha.1 devnum"
