install_mode is ignored

meson-python doesn't set the permissions specified in the install_mode argument of configure_file or install_data. This is useful for configuring files, where you don't want the source file to be executable (since it doesn't work due to the placeholders) but you want it to be executable once installed.

Example:

meson.build

project('meson-python-bug', version: '0.1.0')

configure_file(
    input: 'meson_python_bug.py.in',
    output: 'meson_python_bug.py',
    configuration: { 'greeting': 'Hello, Meson!' },
    install: true,
    install_dir: get_option('bindir'),
    install_mode: 'rwxr-xr-x',
)

meson_python_bug.py.in (rw-r--r--)

#!/usr/bin/env python3
print("@greeting@")

pyproject.toml

[build-system]
build-backend = 'mesonpy'
requires = ['meson-python']

Installing this minimal example using meson/ninja directly works, but installing via pip install . and trying to run meson_python_bug.py gives an error: bash: /home/jwestman/.local/bin/meson_python_bug.py: Permission denied.

Inizia con l’esempio minimo in meson.build, meson_python_bug.py.in e pyproject.toml, quindi confronta l’installazione diretta di Meson/Ninja con pip install. Traccia come viene gestito install_mode durante la build con pip e verifica il completamento installando l’esempio ed eseguendo meson_python_bug.py senza un errore di permessi.
