Python abstraction for ERC190 packages.

Project description

Join the chat at https://gitter.im/ethpm/lobby CircleCI PyPI version

A Python implementation of the Ethereum Package Manager Specification.

Read more in the documentation on ReadTheDocs.

WARNING!

Py-EthPM is currently in public alpha. Keep in mind: - It is expected to have bugs and is not meant to be used in production - Things may be ridiculously slow or not work at all

Quickstart

pip install ethpm

Developer Setup

If you would like to hack on Py-EthPM, please check out the Ethereum Development Tactical Manual for information on how we do:

  • Testing

  • Pull Requests

  • Code Style

  • Documentation

Developer Environment Setup

You can set up your dev environment with:

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

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 py-ethpm/ tests/ -c "clear; flake8 py-ethpm 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 <REPO_NAME> failed'" ../tests ../<MODULE_NAME>

How to Execute the Tests?

  1. Setup your development environment.

  2. Execute tox for the tests

There are multiple components of the tests. You can run test to against specific component. For example:

# Run Tests for the Core component (for Python 3.5):
tox -e py35

# Run Tests for the Core component (for Python 3.6):
tox -e py36

If for some reason it is not working, add --recreate params.

tox is good for testing against the full set of build targets. But if you want to run the tests individually, py.test is better for development workflow. For example, to run only the tests in one file:

pytest tests/ethpm/utils/test_uri_utils.py

IPFS integration tests (tests/ethpm/integration/) require a direct connection to an IPFS node and are skipped by default (except in CircleCI, where they are run). To include these tests in your test run, first start an IPFS node and then add --integration to the pytest command.

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.

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"

EthPM-Spec

  • EthPM-Spec <https://github.com/ethpm/ethpm-spec>__ is referenced inside this repo as a submodule.**

  • If you clone this repository, run this command to fetch the contents of the submodule

git submodule init
