This needs to land ideally by ~Monday and with long CI queues, bumping the priority to help ensure that.

theemathas · 2026-07-05T05:25:43Z

@JonathanBrouwer @Mark-Simulacrum The relevant test seems to be hard-coding version 1.99.0 as a "version far in the future". So, this isn't a spurious failure.

JonathanBrouwer · 2026-07-05T05:27:18Z

Oh you're right, sorry. Should've read the diff better

cargo-side patch: rust-lang/cargo#17179

I think that means for this to be possible to bump, might need a cargo submodule bump that includes that patch...?

…note_over_too_new_note` test (rust-lang#17179) ### What does this PR try to resolve? Unblock (IINM after a submodule update that includes this patch) version bump to 1.99.0 by using a larger placeholder future rust version in `report_rust_version_note_over_too_new_note` test. See rust-lang/rust#158740 (comment). * In the compiler, the {major, minor, patch} numbers are currently represented via `u16` in *several* places, so I elected to use `u16::MAX` here. We should be good for *a while*. ### How to test and review this PR? Exercise normally through CI.

weihanglo · 2026-07-05T14:31:14Z

rust-lang/cargo#17179 is merged. Feel free to bump the submodule in this PR. It should not have anything too unpleasant

Also blesses tests for new deprecations.

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

This is primarily needed for the last merged PR, which fixes Cargo's tests after rustc version is bumped to 1.99.

rustbot · 2026-07-05T15:17:32Z

⚠️ Warning ⚠️

Some commits in this PR modify submodules.

If this was not intentional, see I changed a submodule on accident in the rustc dev guide.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
