Python/CPython missing? (regression in tag-only GitHub in 1.6.0 & 2.0)

[henryiii]

We use last version in manylinux to detect the latest version of each release of Python. For some reason, it suddenly as stopped working; and if I run it manually:

$ pipx run lastversion python/cpython
No release was found

I get nothing, as well.

This worked in our weekly update a week ago, and was broken last night. See pypa/manylinux#1207.

This doesn't seem to work either: pipx run --spec "lastversion<2" lastversion python/cpython, so maybe it's a change in how these are reported from GitHub? (Or maybe it was always pulled from a different endpoint, but I don't know which one or why it's broken now).

I'm thinking this is not looking at the tags, but just at the GitHub Releases (which python/cpython does not have):

lastversion.lastversion - INFO - Verbose 2 level output.
lastversion.lastversion - INFO - Using cache directory: /Users/henryschreiner/Library/Caches/lastversion.
lastversion.ProjectHolder - INFO - Created instance of GitHubRepoSession

Yes! This is a bug introduced in 1.6.0:

$ pipx run --spec lastversion==1.5.1 lastversion  python/cpython
3.10.0
$ pipx run --spec lastversion==1.6.0 lastversion  python/cpython
No release was found
$ pipx run --spec lastversion==2.0.0 lastversion  python/cpython
No release was found

An alias python -> python/cpython would be nice for performance, by the way.

Please check with lastversion 2.0.1.

It actually seems like a change with GitHub in regards to release feeds generation. Previously, I reckon they always included "tag-only" releases even when no formal release was present. And lastversion had some optimization to reduce API usage by leveraging this.

Works, thanks!

$ pipx run --no-cache lastversion python
3.10.0
