# PortKeeper

Reserve and manage localhost hosts/ports for starting servers. Transparently updates `.env` and `config.json` files and keeps a local registry so multiple processes and users can coordinate port reservations.

## Features
- Reserve a free port (optionally with preferred port or a search range)
- Optionally hold the port by binding a dummy socket (prevents others from taking it)
- Release reservation
- Atomic updates to `.env` and `config.json` (with backup)
- Simple file locking to avoid races
- Context manager API and a tiny CLI (`portkeeper`)

## Quickstart
```bash
pip install portkeeper

# Reserve preferred 8888 or a port in 8888-8988, hold it, and print JSON
portkeeper reserve --preferred 8888 --range 8888 8988 --hold --owner myapp

# From Python
from portkeeper import PortRegistry
with PortRegistry().reserve(preferred=8888, port_range=(8888, 8988), hold=True) as r:
    PortRegistry().write_env({'PORT': str(r.port)})
```

## CLI
- `reserve [--preferred P] [--range START END] [--hold] [--owner OWNER] [--write-env KEY]`
- `release PORT`
- `status` (list reserved ports in registry)
- `gc` (garbage-collect stale registry entries)

## Publishing to PyPI

To publish the PortKeeper package to PyPI, you need to set up your credentials. You can do this in one of two ways:

### Option 1: Environment Variables (Recommended)

Set the following environment variables in your shell configuration (e.g., `.bashrc`, `.zshrc`) or in your CI/CD environment:

```
export TWINE_USERNAME="__token__"
export TWINE_PASSWORD="pypi-<YOUR_TOKEN>"
```

Replace `<YOUR_TOKEN>` with your actual PyPI API token. You can generate a token in your PyPI account settings under "API tokens".

### Option 2: Configuration File

Alternatively, you can configure your credentials in a `~/.pypirc` file:

```
[distutils]
index-servers =
  pypi
  testpypi

[pypi]
username = __token__
password = pypi-<YOUR_TOKEN>

[testpypi]
username = __token__
password = pypi-<YOUR_TEST_TOKEN>
```

### Publishing Commands

Once your credentials are set up, you can use the following Makefile commands:

- `make build` - Build the package (wheel and sdist)
- `make publish` - Build and upload to PyPI
- `make publish-test` - Build and upload to TestPyPI
- `make release-patch` - Bump patch version, build, and publish to PyPI
- `make release-minor` - Bump minor version, build, and publish to PyPI
- `make release-major` - Bump major version, build, and publish to PyPI
- `make sign-artifacts` - Sign distribution artifacts with GPG (if available)

**Note**: Make sure to test your package on TestPyPI before publishing to the main PyPI repository.
