Souce code getting packaged in python wheel - python-3.x

Question

We are using the wheels to deploy our code to QA/Production. Recently we found/realized that wheel packages are actually storing our source code. And by simple command as below will open all the source code inside it.
unzip package.whl
command used for wheel creation is as below
cd /path/to/source/code/folder
python setup.py bdist bdist_wheel
So,
Is there any way to create wheels which creates binary and stores in package rather than source code?

Answer 1

In the simplest sense, wheel is just:
a zip file
with a specific filename
and a specific directory layout
containing pure-Python source code
and any platform-specific binaries
This means that a wheel (and any other distribution) is not a binary itself, but it may contain platform-specific binaries -- for example, if you are building/compiling some C code along with your Python package.
Most wheels are pure-Python, which means that they only contain Python source code.
It seems like you're asking how to "compile" Python code into an obfuscated binary. This is not the goal of a wheel. You might want to read more details on the wheel format here: https://www.python.org/dev/peps/pep-0427/

Not with the wheel format. If this is actually your goal, you may want to look into pyinstaller, py2exe or cython, depending on the target platform.

Answer 2

In a case someone stumbles here the same way I did. If you
Use Cython to pre-compile your library.
Have not only .pyx, but also .py modules. For example you want to do this with some existing project without any modifications (except for setup.py), or consider it unreasonable to do in the first place as Cython consumes .py files also).
Want to distribute pre-compiled library without any .py files included (except for may be empty __init__.py files).
Then, you can apply the following (quite dirty) solution to exclude any files you want from the wheel:
from wheel.bdist_wheel import bdist_wheel
class CommandBdistWheel(bdist_wheel):
# Called almost exactly before filling `.whl` archive
def write_wheelfile(self, *args, **kwargs):
dr = f'{self.bdist_dir}/<package name>'
paths = [
path for path in glob.glob(f'{dr}/**/*.py', recursive=True)
if os.path.basename(path) != '__init__.py'
]
for path in paths:
os.remove(path)
super().write_wheelfile(*args, **kwargs)
setup(
# ...
cmdclass={'bdist_wheel': CommandBdistWheel},
# ...
)
