Python Portable Package

Build system for a portable Python distribution.

Used by Chevah's Buildbot setup to generate and publish binary Python packages for a variety of platforms.

Please check https://github.com/chevah/python-package/releases for latest packages. For older releases or platforms no longer supported, please check https://binary.chevah.com/production/python/.

Building steps:

  • Login to a system running on the desired platform (e.g. Ubuntu Server 20.04).
  • Get the code for this repository from GitHub.
  • ./brink.sh detect_os
  • ./chevah_build build
  • ./chevah_build test
  • ./chevah_build compat

You can try the above steps on your own to build and test a new Python package.

Use ./chevah_build help to discover all available commands.

New testing packages are uploaded automatically for green GitHub builds at https://bin.chevah.com:20443/testing/.

Production packages are available both through GitHub releases and at https://bin.chevah.com:20443/production/.

Patching upstream code

This repository contains a lot of imported code from upstream repos: Python, OpenSSL, SQLite, libffi, etc.

You can find those sources in two sub-directories:

  • src/
  • python-modules/

Local changes to upstream projects are kept separated from upstream code. For every problem we fix downstream, there's a patch to be applied at build time. Those patches are kept in one of these places:

  • src/$PROJECT/*.patch
  • python-modules/$PROJECT-$VERSION-patches/

New patches added as documented above will be picked up automatically by the build system.

An example for creating a patch for src/python/Python-2.7.13/Lib/site.py:

cd src/python/Python-2.7.13/
cp Lib/site.py Lib/site-patched.py
# Edit Lib/site-patched.py as needed, then create the diff.
diff -ur Lib/site.py Lib/site-patched.py
# Save the diff result, including the command line into a patch file,
# for example:
src/python/this-fixes-something.patch

External dependencies and associated vulnerabilities

This Python package builds and/or links to third-party libraries.

Their known vulnerabilities are documented for all OS'es in the LibreOffice spreadsheet external_deps.fods.

For your convenience, this flat ODS file is also exported in CSV format as external_deps.csv.
