.data directory in generated wheels has the wrong name

[ejd]

Bug Description

According to the wheel spec, a wheel's ".data" directory wheel should have the same basename as the ".dist-info" directory.

Currently, maturin uses distribution.data for the directory name. The name should be, for example, distribution-1.0.data.

Your maturin version (maturin --version)

1.7.8

Your Python version (python -V)

Python 3.8.19

Your pip version (pip -V)

pip 24.3.1

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

set -eux
mkdir example
cd example
maturin init --bindings pyo3
mkdir -p example.data/data
echo "text" > example.data/data/dummy.bin
RUST_LOG=maturin=debug maturin build --color never
unzip -l target/wheels/example-0.1.0-cp38-cp38-manylinux_2_34_x86_64.whl
