lasso-python

lasso-python is the canonical Service Lasso service repo for packaging Python as a release-backed runtime provider.

The repo does not fork Python. It downloads official Python.org release artifacts, wraps the supported portable runtime shape in Service Lasso-compatible archives, and publishes those archives from protected main pushes using the project version pattern:

yyyy.m.d-<shortsha>

This repo is public. It is not marked as a GitHub template today; app templates should consume the released service.json pattern rather than clone this packaging repo.

Distribution Decision

The first lasso-python release uses official Python.org Windows embeddable ZIPs:

• Python 3.11.5: python-3.11.5-embed-amd64.zip
• Python 3.14.4: python-3.14.4-embed-amd64.zip

Python.org does not publish equivalent general-purpose Linux/macOS portable runtime archives. Linux and macOS are therefore intentionally unsupported for this first release-backed provider until a separate portable distribution strategy is approved.

Release Assets

Each release publishes:

• lasso-python-3.11.5-win32.zip
• lasso-python-3.14.4-win32.zip
• service.json
• SHA256SUMS.txt

The released service.json selects Python 3.11.5 as the default provider version.

Release Contract

Release tags use the Service Lasso version pattern:

yyyy.m.d-<shortsha>

The released service.json keeps artifact.source.channel set to latest so new consumers can track the newest Python provider packaging release intentionally. Core service-lasso may pin a specific release tag in its own optional provider manifest after verification.

Each platform archive contains:

• python.exe
• Python embedded runtime files from Python.org
• SERVICE-LASSO-PACKAGE.json

SERVICE-LASSO-PACKAGE.json records:

• Service Lasso service id: @python
• upstream project: python/cpython
• upstream Python version
• upstream asset name and URL
• packaging repo: service-lasso/lasso-python
• target platform and architecture

Local Verification

npm test

This packages Python 3.11.5 by default, extracts the archive, verifies package metadata, and runs python --version from the extracted payload.

To verify Python 3.14.4:

$env:PYTHON_VERSION = "3.14.4"
npm test

Service Lasso Contract

The service manifest declares:

• provider role with no managed daemon start requirement
• native archive acquisition from GitHub releases
• Python 3.11.5 as the default runtime artifact
• PYTHON, PYTHON_HOME, and PYTHONPATH provider/global environment hints
• provider version proof using python --version
