Wrong Version detected with project_wheel_metadata

[finswimmer]

Hello,

I'm not sure whether this is a problem with build, pep517, importlib.metadata or something different.

I triaged a potential bug in poetry 1.2.0a2 and realized the following:

When I build a wheel for the current sqlalchemy from it's main branch - after cloning the repo - by python -m build the Version field in METADATA is 2.0.0b1.dev0.

But when I run this in a python console the result is different:

import build.util
meta = build.util.project_wheel_metadata(".")
meta.get("Version")
'2.0.0b1.dev0dev'

As you can see there's an additional dev at the end of the version.

Any ideas what's going on?

Python: 3.10.2
build: 0.7.0

project_wheel_metadata doesn't build an intermediate sdist so I'd start by checking what the version for python -m build -w is.

Okay, the prepare_metadata_for_build_wheel hook produces '2.0.0b1.dev0dev'. This is most likely a bug in how dist_info processes tag_build - I can reproduce it with python setup.py dist_info.

Yeah, it seems like a bug in setuptools.

@jaraco could you transfer the issue?

A similar issue was reported in this comment. There may already be a bug reported about it. I'd appreciate help to triage.
