RUST COMPILER TIGHTENS LINT PASSES, STDARCH SUBTREE SYNCS, CRATES.IO FIXES INDEX CLONE

By RepoJournal · Filed · About Rust

The compiler team converted strict provenance lints to proper late passes [ref:8], fixing a clippy interop problem while suppressing garbled suggestions in macros.

Three compiler rollups landed overnight across cast checking, test infrastructure, and documentation [1] [2]. The strict provenance lint migration [3] moves `lossy_provenance_casts` and `fuzzy_provenance_casts` out of hardwired type checking into standard lint passes, which solves a problem where clippy couldn't reuse the cast checking code without inheriting those diagnostics. The same work includes a fix for garbled suggestions when those lints fire inside macros [4], where span arithmetic previously produced broken output like `$e as ).addr()`. Separately, rust-analyzer patched a technically overlapping interned value issue in `SyntaxContext::root` [5] while hardening the API to prevent proc-macro servers from accidentally depending on root encoding details. Over on crates.io, the team fixed a critical bug where the index archive job couldn't clone the repository over SSH without proper key setup [9], rewiring it to use HTTPS for read-only access since the deploy key wasn't wired into that job context. Storybook and Percy CLI dependencies received routine updates [6] [7], and diesel-guard bumped its migration guard rules past existing migrations [8].
