03/14/2022, 10:11 PMDocs on Python third-party dependencies are rewritten to talk about the highly-requested feature of proper lockfiles (e.g. --hash support) and multiple lockfile support! https://www.pantsbuild.org/v2.10/docs/python-third-party-dependencies
As discussed there, these features are both ready to be used in Pants 2.10, with the big caveat that Pants's automated generation of the lockfiles might not yet work in your repo.
Feedback welcomed š„³

03/14/2022, 10:12 PMFYI what changed:
ā¢ warning about multiple conflicting versions https://www.pantsbuild.org/v2.10/docs/python-third-party-dependencies#warning-multiple-versions-of-the-same-dependency
ā¢ lockfiles section is totally redone https://www.pantsbuild.org/v2.10/docs/python-third-party-dependencies#lockfiles
ā¢ No more generate_constraints.sh script to get an IDE set up! ./pants export can do it https://www.pantsbuild.org/v2.10/docs/python-third-party-dependencies#tip-use-pants-export-to-create-a-virtual-environment-for-ides

03/14/2022, 10:58 PMHow do you know if you have one of those might-not-yet-work cases? š Tried the resolves feature out just now with a Pants-generated lockfile and was met by this by one of the dependencies when running `check`:

03/14/2022, 11:02 PMThe docs try to explain it, but basically:
ā¢ 3 categorical times it won't work
ā¢ an edge case you are likely to encounter and how to workaround it
For this particular issue you're getting, huh..Could you please move that to either #development or a GitHub issue so that we can debug there?

03/14/2022, 11:16 PMJonas pointed out that Pants 2.10.0rc3 is unlikely to work due to some Pex issues that were recently fixed. I'm doing a release later today; otherwise early adopters can set
