maturin build & upload fails due to "malformed summary"

[messense]

I'll push a new release after work.

For now, if anyone is blocked by this, switch to twine for upload.

I'm also running into this issue, but it seems to me that the correct key in pyproject.toml is in fact description, not summary: https://packaging.python.org/en/latest/specifications/pyproject-toml/#description
It mentions that this should be exported as summary in the metadata of the wheel however.

Here is a log from such an upload
https://github.com/pymc-devs/nutpie/actions/runs/8360753012/job/22888798313

And the corresponding pyproject file:
https://github.com/pymc-devs/nutpie/blob/8fdb3b69a672a08cb1cf71d9bd6f2fc79b6d3cdd/pyproject.toml

@ion-elgreco Can you run twine check on that wheel file?

[messense]

Sorry but you also need to share your binding code, at least pyproject.toml, Cargo.toml and readme file.

Hi sorry for the slow reply, after making some assumptions as to what summary exactly is, I managed to solve the issue by changing my pyproject.toml's description key to summary, everything else stayed the same. I am not very well-versed with the Python standard for metadata so I'd assume a revision was made recently? I've had this pyproject.toml set up since the beginning of the project. Thanks for the prompt reply @messense!

I'm also facing this issue, and it's also my understanding that description should be the correct key.

E.x. from my project: https://github.com/wheretrue/biobear/actions/runs/8368683483/job/22915105523

[leeian1011]

Decided to reopen as there are others facing the same issues

[ion-elgreco]

Our releases at Delta-rs are also failing suddenly: https://github.com/delta-io/delta-rs/actions/runs/8365191045/job/22918909428#step:3:1

[messense]

@ion-elgreco Can you unpack the wheel that fails the upload and paste it's metadata content here?

[ion-elgreco]

@messense not sure how to download the wheel from the failed action, if you have some pointers?

But from a locally built release with maturin, the description looks fine:

[messense]

That Summary looks fine to me?

https://packaging.python.org/en/latest/specifications/core-metadata/#core-metadata-summary

A one-line summary of what the distribution does.

[ion-elgreco]

That Summary looks fine to me?

https://packaging.python.org/en/latest/specifications/core-metadata/#core-metadata-summary

A one-line summary of what the distribution does.

That's the confusing part, nothing changed on our side in the description between 0.16.1 and 0.16.2. Both were built with maturin 1.5.

@messense I did yesterday, twine check passed on that wheel

[ion-elgreco]

[messense]

Maybe it's related to this pypi change: pypi/warehouse#15631

[ion-elgreco]

Looks to be re raised from there: https://github.com/pypi/warehouse/pull/15631/files#diff-631b24361675bcbc0f1aa65df703ce99f10d505f6d95a067c7e1f33fd961ee86R327

So for some reason summaries are not parsed anymore?

[aseyboldt]

Here is a metadata file from one of the wheels that showed this error. I could upload the file using twine without issues.

## Installation

[messense]

Can anyone try #2002? Clone this repo and switch to that branch and run cargo run upload ....

[ion-elgreco]

@messense I am at work atm, I can trigger a new CI though if you already push a release, since it will automatically pick up the new version; p

[ion-elgreco]

@messense Thankss!

[ion-elgreco]

@messense our releases are working again, thanks for the quick fix <3
