wheel2deb: python wheel to debian package converter

wheel2deb: python wheel to debian package converter

wheel2deb basically takes a list of wheels as input and produces a list of debian binary CPython packages (those prefixed with python- or python3-).

Quick Example

The following shows how to convert numpy and pytest, along with their dependencies into a list of debian packages:

# Download (and build if needed) pytest, numpy and their requirements
pip3 wheel pytest numpy
# Convert all wheels to debian source packages
wheel2deb --map attrs=attr
# Call dpkg-buildpackages for each source package
wheel2deb build
ls -l output/*.deb
# Install generated packages
dpkg -i output/*.deb
# Run pytest on numpy
python3 -c "import numpy; numpy.test()"

Project scope

• Python 2.7 and 3
• CPython only for now
• support for non pure python wheels
• support debian architectures all, armhf, amd64, i686
• tested on jessie, stretch, buster so far, ubuntu should also work

Requirements

wheel2deb uses python3-apt to search for debian packages, dpkg-shlibdeps to calculate shared library dependencies and apt-file to search packages providing shared library dependencies. wheel2deb build requires the usual tools to build a debian package:

apt update
apt install python3-apt apt-file dpkg-dev fakeroot build-essential devscripts debhelper
apt-file update

If you want to cross build packages for ARM, you will also need to install binutils-arm-linux-gnueabihf.

Converting pure python wheels, don't actually requires apt-file and dpkg-dev.

Keep in mind that you should only convert wheels that have been built for your distribution and architecture. wheel2deb will not warn you about ABI compatibility issues.

Installation

wheel2deb is available from pypi:

pip install wheel2deb

Docker images for jessie, stretch and buster are also available from the docker hub:

docker run -ti -v $(pwd):/data wheel2deb:stretch

Features

• guess debian package names from wheel names and search for them in the cache
• search packages providing shared library dependencies for wheels with native code
• handle entrypoints and scripts (those will be installed in /usr/bin with a proper shebang)
• try to locate licence files and to generate a debian/copyright file

Options

Use wheel2deb --help and wheel2deb build --help to check all supported options

Option	Description
-v	Enable debug logs.
-x	List of search paths where to look for python wheels. Defaults to current directory. Not recursive.
-o	Output directory where debian source packages will be produced. Defaults to ./output
-i	List of wheel names to convert. By default all found wheels are included.
--python-version	cpython version on the target debian distribution. Defaults to platform version (example: 3.4).
--map	list of string pairs to explicitely map python dist names to debian package names. For instance: "--map foo:bar attrs:attr" will tell wheel2deb to map foo to python-bar and attrs to python-attr.
--depends	List of additional debian dependencies.
--epoch	Debian package epoch. Defaults to 0.
--revision	Debian package revision. Defaults to 1.
--ignore-entry-points	Don't include the wheel entrypoints in the debian package.
--ignore-upstream-version	Ignore version specifiers from wheel requirements. For instance, if foo requires bar>=3.0.0, using this option will produce a debian package simply depending on bar instead of "bar (>= 3.0.0)".
