## Summary
Hatch allows for highly dynamic customization of metadata via hooks. In
such cases, Hatch
can't upload the PEP 517 contract, in that the metadata Hatch would
return by
`prepare_metadata_for_build_wheel` isn't guaranteed to match that of the
built wheel.
Hatch disables `prepare_metadata_for_build_wheel` entirely for pip.
We'll instead disable
it on our end when metadata is defined as "dynamic" in the
pyproject.toml, which should
allow us to leverage the hook in _most_ cases while still avoiding
incorrect metadata for
the remaining cases.
Closes: https://github.com/astral-sh/uv/issues/2130.
We put a `.gitignore` with `*` at the top of our cache. When maturin was
building a source distribution inside the cache, it would walk up the
tree to find a gitignore, see that and ignore all python files. We now
add an (empty) `.git` directory one directory below, in the root of
built-wheels cache. This prevents ignore walking further up (it marks
the top level a git repository).
Deptry (from #2490) is a mid sized rust package with additional python
packages, so instead of using it in the test i've replaced it with a
small (44KB total) reproducer that uses cffi for faster building, the
entire test taking <2s on my machine.
Fixes#2490
