# PyPI Publishing Guide

## 1. Package Naming & Identity

```
PyPI name:      edgequake-python
Import name:    edgequake_python
Version scheme: 0.MAJOR.MINOR  (e.g. 0.1.0, 0.2.0)
                - 0.x = pre-stable, breaking changes allowed
                - 1.0.0 = stable litellm-compatible API locked

Alternative names considered:
  eq-llm          (too terse)
  edgequake-llm   (clashes with Rust crate on crates.io)
  fast-litellm    (trademark concerns)
  edgequake-python ✓ (clear, namespaced, no conflicts)
```

## 2. Wheel Matrix

maturin builds platform-specific wheels. We need all of:

```
Platform         Architecture   Python ABI     Wheel tag
────────────────────────────────────────────────────────────────────────────
Linux (glibc)    x86_64         abi3 (3.9+)    cp39-abi3-manylinux_2_17_x86_64
Linux (glibc)    aarch64        abi3 (3.9+)    cp39-abi3-manylinux_2_17_aarch64
Linux (musl)     x86_64         abi3 (3.9+)    cp39-abi3-musllinux_1_2_x86_64
macOS            x86_64         abi3 (3.9+)    cp39-abi3-macosx_10_12_x86_64
macOS            arm64          abi3 (3.9+)    cp39-abi3-macosx_11_0_arm64
macOS (uni2)     x86_64+arm64   abi3 (3.9+)    cp39-abi3-macosx_11_0_universal2
Windows          x86_64         abi3 (3.9+)    cp39-abi3-win_amd64
```

With `abi3-py39` in PyO3 features, **one build per platform** works for
Python 3.9 through 3.13+.

## 3. pyproject.toml Configuration

```toml
[build-system]
requires = ["maturin>=1.7,<2.0"]
build-backend = "maturin"

[project]
name            = "edgequake-python"
version         = "0.1.0"
description     = "Rust-powered LiteLLM-compatible LLM client"
readme          = "python/README_PYPI.md"
license         = { text = "Apache-2.0" }
requires-python = ">=3.9"
dependencies    = ["pydantic>=2.0"]
keywords        = ["llm", "openai", "anthropic", "litellm", "rust", "performance"]
classifiers = [
    "Development Status :: 3 - Alpha",
    "Intended Audience :: Developers",
    "License :: OSI Approved :: Apache Software License",
    "Programming Language :: Python :: 3",
    "Programming Language :: Rust",
    "Topic :: Scientific/Engineering :: Artificial Intelligence",
    "Typing :: Typed",
]

[project.optional-dependencies]
async = ["anyio>=4.0"]
all   = ["anyio>=4.0", "openai>=1.0"]

[project.urls]
Homepage      = "https://github.com/raphaelmansuy/edgequake-llm"
Documentation = "https://docs.rs/edgequake-llm"
Repository    = "https://github.com/raphaelmansuy/edgequake-llm"
"Bug Tracker" = "https://github.com/raphaelmansuy/edgequake-llm/issues"
Changelog     = "https://github.com/raphaelmansuy/edgequake-llm/blob/main/CHANGELOG.md"

[tool.maturin]
python-source = "python"
module-name   = "edgequake_python._eq_core"
features      = ["python"]
```

---

## 4. Release Process

```
Step 1: Tag the release
   git tag py-v0.1.0
   git push origin py-v0.1.0

Step 2: GitHub Actions triggers python-publish.yml
   Builds wheels for all 7 platform/arch combos
   Runs smoke tests on each wheel
   Uploads artifacts

Step 3: Publish to PyPI via trusted publishing (OIDC)
   No token needed — GitHub Actions OIDC → PyPI
   pypa/gh-action-pypi-publish@release/v1

Step 4: Verify
   pip install edgequake-python==0.1.0
   python -c "from edgequake_python import completion; print('OK')"
```

---

## 5. Trusted Publishing Setup (PyPI side)

```
1. Go to https://pypi.org/manage/project/edgequake-python/settings/publishing/
2. Add new publisher:
   - Owner:      raphaelmansuy
   - Repository: edgequake-llm
   - Workflow:   python-publish.yml
   - Environment: pypi
3. No API token needed in GitHub secrets
```

---

## 6. SDist (Source Distribution)

```bash
# Build sdist (needed for pip install from source)
maturin sdist --features python

# This creates:
#   target/wheels/edgequake_python-0.1.0.tar.gz
#
# Contains all Rust source, Cargo.toml, pyproject.toml, python/ directory
# pip install edgequake-python will:
#   1. Download sdist
#   2. Invoke maturin as PEP-517 backend
#   3. cargo build --release --features python
#   4. Install resulting .so + Python files
```

---

## 7. Versioning Strategy

```
edgequake-python version  Rust crate version  Notes
──────────────────────────────────────────────────────────────────
0.1.x                     0.2.x               Alpha — API may change
0.2.x                     0.2.x               Beta — deprecation warnings
1.0.x                     1.0.x               Stable — litellm API locked
1.x.x                     1.x.x               Semver stable

Python package version is independent from Rust crate version.
Both live in the same repo but are published separately:
  - Rust:   crates.io/crates/edgequake-llm
  - Python: pypi.org/project/edgequake-python
```

---

## 8. Local Development Workflow

```bash
# Clone repo
git clone https://github.com/raphaelmansuy/edgequake-llm.git
cd edgequake-llm

# Create Python venv
python -m venv .venv
source .venv/bin/activate

# Install maturin
pip install maturin

# Install in dev mode (recompile Rust on each `maturin develop`)
maturin develop --features python

# Now you can import:
python -c "import edgequake_python; print(edgequake_python.__version__)"

# After modifying Rust code:
maturin develop --features python  # recompile + reinstall

# Run Python tests:
pip install pytest pytest-asyncio
pytest tests/python/ -v
```

---

## 9. README_PYPI.md (snippet)

```markdown
# edgequake-python

Rust-powered drop-in replacement for [LiteLLM](https://github.com/BerriAI/litellm).

## Install

    pip install edgequake-python

## Usage

    import edgequake_python as litellm   # drop-in

    response = litellm.completion(
        model="openai/gpt-4o",
        messages=[{"role": "user", "content": "Hello!"}],
    )
    print(response.choices[0].message.content)

## Why faster?

- HTTP layer: Rust + reqwest (no Python event loop overhead)
- Zero-copy JSON: serde_json (vs Python dict allocations)
- Streaming: Rust SSE parser (vs Python line-split loops)
- No tiktoken import on startup (~300ms saved)

## Benchmark

| Scenario           | litellm | edgequake-python | Speedup |
|--------------------|---------|-----------------|---------|
| Overhead per call  | ~6 ms   | ~0.4 ms         | 15×     |
| Import time        | ~800 ms | ~50 ms          | 16×     |
| 100 concurrent req | ~45 MB  | ~8 MB           | 5.6×    |

(Measured: MacBook Pro M3, gpt-4o-mini, 200-token response)
```
