Invalid package metadata versions? #1359

Open bepri opened 5 days ago

bepri commented 5 days ago

I think the METADATA files distributed with attrs versions 23.2.0 and 24.2.0 specify a Metadata-Version that is too low for the keys they contain. According to the METADATA specification, the License-Expression and License-File keys are not supported until v2.4, but the two versions I tested use those keys and claim to be using v2.1 and v2.3, respectively.

When parsing the METADATA file for attrs-23.2.0 with packaging.metadata.parse_email(), I get the following exception:

packaging.metadata.ExceptionGroup: ('unparsed', [InvalidMetadata("unrecognized field: 'license-file'"), InvalidMetadata("unrecognized field: 'license-expression'")])

I'm not sure what to do about that. All this data ist coming from hatchling and I have no influence over it whatsoever.
