5 days ago Hi @davebelais thank you very much for reporting this.
Before we dive into investigation, could you please review the reproducer a little bit? If I understand the text of PEP 517 correctly the value passed to the build_wheel hook must be the same as returned by prepare_metadata_for_build_wheel, not the one passed in. So probably something like this:
import tempfile from setuptools
import build_meta
metadata_directory: str = tempfile.mkdtemp()
dist_directory: str = tempfile.mkdtemp()
build_meta.build_sdist(dist_directory)
metadata_directory = build_meta.prepare_metadata_for_build_wheel(metadata_directory)
build_meta.build_wheel(
dist_directory,
metadata_directory=metadata_directory, # UPDATE: this is also wrong see below.
)Could you please check if the error still happens after reviewing the reproducer in the light of this nuance of PEP 517?
UPDATE: See below.

Description
Something went awry with building wheel metadata in 75.2.0...
To replicate, use the following:
Here's the output from the last line above when run w/ v75.1.0 (I am using this repo):
Here's the output from the last line of the same script w/ v75.2.0:
...notice how the *.dist-info is double-nested when run in v75.2.0. This breaks the wheel, of course.
Expected behavior
I tried building a wheel using
