Miri's Priroda interpreter now ships with full Debug Adapter Protocol support for VS Code and nvim-dap, while the Rust compiler removes unused attribute complexity and patches a Windows stack buffer issue.

The Priroda team merged a complete DAP frontend [1] that enables single-thread stepping, breakpoint management, and macro span resolution in any editor supporting the Debug Adapter Protocol. This follows infrastructure work centralizing request handling [2] and eliminating redundant termination guards [3] that were dead code. The refactoring bubbles predicate failures through a unified HandlerError type [4], making error handling and response sequencing explicit and testable.

On the compiler side, rustc landed a fix for a stack buffer overflow in Windows junction_point handling [5] and removed the OnDuplicate::Custom variant that was only helpful for a single attribute [6]. A resolver PR introduces unsafe speculative flag handling for tracked borrows in CmRefCell [7], improving the clarity of borrow tracking in name resolution. Two rollups merged across 37 PRs total [5] [8].

The crate registry continues steady automation: sui-resolve, sui-bytecode, unstave-core, sui-spec, and monad-revm all bumped [9] [10] [11] [12] [13]. This Week in Rust published issue 663 [14] with notable changes and quote of the week under review [15].

Action items

→ Review Priroda DAP support if you use miri for interactive debugging rust-lang/miri [monitor]
→ Pull the Windows junction_point overflow fix if you build on Windows rust-lang/rust [plan]
→ Update sui ecosystem crates if you depend on them rust-lang/crates.io-index [plan]
