Implementation of the P2P Discoveryv5 Protocol

Read more in the [documentation on ReadTheDocs](https://ddht.readthedocs.io/). [View the change log](https://ddht.readthedocs.io/en/latest/releases.html).

## Quickstart

```sh
pip install ddht
```

To run it:

```sh
ddht
```

`--help` will tell you about the arguments `ddht` accepts. The LOGLEVEL environment
variable can be used to control which log messages are emitted. For example, to suppress
unimportant messages from the Packer you can run:

```sh
LOGLEVEL=WARNING:ddht.v5.packer.Packer ddht
```

## Developer Setup

If you would like to hack on ddht, please check out the [Snake Charmers
Tactical Manual](https://github.com/ethereum/snake-charmers-tactical-manual)
for information on how we do:

- Testing
- Pull Requests
- Code Style
- Documentation

### Development Environment Setup

You can set up your dev environment with:

```sh
git clone git@github.com:ethereum/ddht.git
cd ddht
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:

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

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

```sh
# 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:

```sh
cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on ddht failed'" ../tests ../ddht
```

### Release setup

For Debian-like systems:
```
apt install pandoc
```

To release a new version:

```sh
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"`
