Poetry build sets python core metadata summary equals description, failing to upload to pypi and pypitest
- Poetry version: 1.6.1
- Python version: Python 3.10
- OS version and name: Ubuntu 22.04
- pyproject.toml: (https://gist.github.com/broeder-j/20eb8dc8046fc004608e6acf3bf36236)
Issue
The python package build successfully by poetry gets rejected from PYPI and PYPI test for having a too long summary (512 chars), a package core metadata property.
From my understanding this occurs because:
- poetry sets per default the summary key for core package metadata equals the projects description or empty. (I have not found any way to provide this metadata key additionally to poetry.)
- The summary metadata string is limited to 512 chars on pypi. (I have not found this specification length detail in the specifications https://packaging.python.org/en/latest/specifications/core-metadata/#summary by python beyond that it should be 'one line'.)
- the 'summary' core metadata key is not part of project metadata, so it cannot be set in the pyproject.toml file.
So currently I am forced by poetry to shorten my projects description, that it also fits into the core metadata summary content for PYPI, or I cannot publish the build package there, or I would have to hack the metadata afterwards.
How this might be solved to my understanding by poetry:
- Either provide an external way to specify the core package metadata, like allowing to set the summary in the tools.poetry section or over the commandline.
- An earlier failure, or warning would be nice, i.e if the summary is to long for a pypi upload, that it does not fail on upload, but fails/warns earlier during build.
- shorten the core package metadata summary by default, if to long, or make it an empty string.
