Description

Files installed via Wheel.install_as_egg have the same file mode as installed via pip install

Expected behavior

Files installed via Wheel.install_as_egg have the same file mode as installed via pip install. Needed here https://github.com/buildout/buildout/issues/604

How to Reproduce

Install via pip:

virtuelenv env
env/bin/pip install kaleido

Check mode:

❯ stat -c "%a" env/lib/python3.8/site-packages/kaleido/executable/kaleido                                         
755

Install via install_as_egg:

import setuptools.wheel

if __name__ == "__main__":
    whl = setuptools.wheel.Wheel("kaleido-0.2.1-py2.py3-none-manylinux1_x86_64.whl")
    whl.install_as_egg("./foo")

Check mode:

❯ stat -c "%a" foo/kaleido/executable/kaleido                 
644

Output

# ABOVE

Start at the setuptools.wheel.Wheel.install_as_egg entry point and reproduce the issue with the kaleido wheel and the provided stat commands. Done means files installed through install_as_egg have the same mode as those installed through pip, including the executable shown in the example.
