test(chore): audit `//@ run-pass` in ui tests by Embers-of-the-Fire · Pull Request #154254 · rust-lang/rust

Embers-of-the-Fire · 2026-03-23T11:14:47Z

Part of work for #154158. The list is non-exhausive and there's definitely parts that I can/will not cover.

Note: still working here with around ~1000 tests to audit and finished ~400 files. Do not merge this but could be reviewed now :)

@rustbot reroll
I'm very busy in my personal life this week and probably the next one as well so will leave review duty for a bit (just changed my triagebot config)

Thank you. Could you let me know when you're ready with @rustbot review and rebase all commits into a single commit at the end? @Embers-of-the-Fire

@Embers-of-the-Fire Could you fix CI failures?

Embers-of-the-Fire · 2026-05-12T07:01:16Z

@TaKO8Ki Most of the errors (at least those I could observe) originate from linter warnings, and I'm not sure if you want me to fix them by 1) switching back to build-pass or run-pass or 2) modify the stderr file?

TaKO8Ki · 2026-05-12T08:42:24Z

@Embers-of-the-Fire These look like stale stderr expectations after the mode change. The actual output is empty, I guess. You can keep check-pass and remove/bless the stale .stderr files with --bless as an example.
