11/19/2025, 11:09 PMChicken and egg problem with 3.14 - to put a test in scie-pants that exercises the Pants version + Python interpreter, I need a release of 3.14 with a release version to target.
To get a release of 3.14 - we should really have a way to run it 😆 Not sure what was done on 3.11 and Pants 2.25
Thoughts?

11/20/2025, 12:27 AMAccording to how the scie-pants tests work (using PANTS_VERSION), we would need to release Pants, THEN test scie-pants, and then release
Or, release scie-pants as-is, then pants, then add the test to scie-pants after the fact and hope nothing bad happens.
There is likely another workaround somewhere, where we like, use PANTS_BOOTSTRAP_URLS to fake the version with a 3.14 pex to apply the test first

11/20/2025, 12:27 AMI thought PANTS_SOURCE was the move, but that'll use system python

11/21/2025, 2:11 AMMaybe you could do a custom release of Pants? I have a modified version of the release workflow for non-official releases. You would just need to update the URLs env var used by scie-pants to point at the alternate release.

11/21/2025, 2:12 AMYou may not even have to do a custom release workflow. Just build a Pants pex with an existing version and set
PANTS_BOOTSTRAP_URLSw

11/21/2025, 2:20 AMThat’s how I’m currently testing it to confirm it works locally, but the scie-pants tests use PANTS_VERSION, which points to pantsbuild/pants. An intermezzo workaround would be to host the pants-pex I use somewhere, and then do the bootstrap urls approach… Then, flip that around once we release

11/21/2025, 2:45 AMbootstrap URLS can be file:// I believe

11/21/2025, 2:50 AMYeah, it can be - but do you mean, commit the pex to the scie-pants repo, and use it there? I was thinking to just host it on my fork and point there (untested, but seems possible)
