Warn when an edition 2021 crate is in a virtual workspace with default resolver by Nemo157 · Pull Request #10910 · rust-lang/cargo

Nemo157 · 2022-07-28T15:51:22Z

Edition 2021 updates the default resolver to version "2", but developers using virtual workspaces commonly don't get this update because the virtual workspace defaults to version "1". Warn when this situation occurs so those developers can explicitly configure their workspace and will be more likely to know that they will need to update it in the future.

Fixes #10112

This is mostly a problem for binary packages, but it does also affect library packages in some situations; e.g. it can cause issues when a different resolver is used while building the docs on docs.rs than when building in the projects CI: tokio-rs/axum#1180

I'll update this based on the discussion in #10112 tomorrow.

Ping @Nemo157. Just checking in to see if you have time and are still interested in working on this. If you have any question, feel free to discuss here or on Zulip.

Sorry about the delay, I finally got around to rebasing and implemented both suggestions from above.

Let me know what your thoughts are on another round for tweaking the messages

I look forward to #12115 since it will open the door for more cargo warnings and we'll be able to have a broader mismatch warning that people can disable.

Thanks @Nemo157 for picking this back up.

@weihanglo I recommend adding resolver = "1" to the rust-lang/rust workspace when you do the next update so that warnings don't start getting generated.

(I recall trying to add resolver = "2" in the past, and it not going well. That should probably be done as a separate PR if anyone wants to try that.)

rust-lang/cargo#10910 starts emitting warning if resolver is not set for 2021 edition package. We want to surpress the warning for now.
