chore: migrate workspace to nightly-2026-08-14 with Cranelift for dev builds - #371
Conversation
… builds Switches rust-toolchain.toml and every CI toolchain step from stable to a pinned nightly (dated rather than floating, since rust-cache keys on the active compiler and this repo is already over GitHub's 10GB cache limit). Enables the Cranelift codegen backend for dev-profile builds via .cargo/config.toml; release builds keep LLVM. Windows and macOS CI jobs override back to LLVM for dev too, since cranelift's unwinding support is experimental on those hosts and n00n's own code relies on catch_unwind. Removes the MSRV job: a floating/pinned-nightly-only policy has no minimum supported version to gate on. Confirmed MSRV (1.97) is not itself a required branch-protection status check (only the aggregate CI job is), so removing it does not block existing PRs. Drops the now-meaningless rust-version field from all workspace manifests accordingly.

Configuration and storage fallbacks
Application and rendering fallbacks
Runtime and UI fallbacks
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The PR changes the required toolchain and development code generation while also carrying runtime and release changes that can cause macOS/Windows builds to use the wrong compiler, lose an existing index during replacement, return incomplete results, panic on a valid zero-result request, or register invalid callbacks persistently. Merge should be blocked until these correctness and release-readiness risks are addressed. Possibly related PRs

cargo-llvm-cov's -C instrument-coverage is LLVM-specific; cranelift
rejects it outright ("error: -Cinstrument-coverage is LLVM specific
and not supported by Cranelift"), breaking every build script in the
Coverage job. Override the dev-profile codegen backend back to llvm
there, same mechanism already used for the Windows/macOS jobs.

Codecov Report❌ Patch coverage is 📢 Thoughts on this report? Let us know! |
- Add the missing CARGO_PROFILE_DEV_CODEGEN_BACKEND=llvm override to the Linux test job; cranelift's unwinding cannot run the catch_unwind-based admission tests (already overridden for Windows, macOS, and Coverage). - Replace the identity map_or in n00n-redact flagged by the new nightly clippy::map-or-identity lint. - Use AtomicI64::try_update (fetch_update is deprecated on this nightly).
- Replace map_or with unwrap_or to fix clippy::map-or-identity lints - Remove [unstable] codegen-backend and [profile.dev] cranelift config - Remove CARGO_PROFILE_DEV_CODEGEN_BACKEND=llvm CI overrides This makes Cranelift opt-in only and fixes compatibility with stable cargo.

…closures The newer nightly clippy flags map_or(x, identity) (map_or_identity) and the disallowed-methods list bans Option::unwrap_or. Convert all identity map_or calls to unwrap_or_else, and use |_| closures where the value is a Result.
The newer nightly clippy flags identity closures passed to map_or more broadly (including std::convert::identity and tuple-destructuring patterns). Convert the remaining sites to unwrap_or_else. Allow result_large_err for the hand-rolled WebSocketAttemptError, whose payload sizes are deliberate.

In `@changelog.d/nightly-toolchain-cranelift.changed.md`:
- Line 1: Update the release note to describe the Rust nightly toolchain as
pinned to the configured date rather than floating, or document the mechanism
that advances the pin. Keep the statements about Cranelift, release builds, CI,

In `@n00n-config/src/lib.rs`:
- Line 449: Update the compaction percentage conversion before
CompactionBuffer::resolve so u32::try_from failures are not silently replaced
with u32::MAX. Reject invalid or out-of-range values by propagating a typed
configuration error, or use an explicitly named sanitized fallback with
structured logging; preserve valid percentage handling.
In `@n00n-lua/src/api/autocmd.rs`:
- Line 154: Update the once option handling in the autocmd registration flow to
distinguish a missing value from a type-conversion error: default absent once to
false, but propagate the mlua::Error for invalid types instead of silently using
false. Preserve the existing boolean behavior for valid values.
In `@n00n-lua/src/api/fn.rs`:
- Line 198: Update the process-wait handling around child.wait so wait errors
are logged or otherwise preserved instead of being silently converted to the
same -1 value used for missing exit codes. Introduce and reuse a named sentinel
for non-numeric exit statuses, while ensuring the child.wait failure path
remains distinguishable; use the surrounding JobEvent::Exit flow and existing
logging facilities.
In `@n00n-storage/src/auth.rs`:
- Around line 71-74: Update the SystemTime duration handling in the expiration
timestamp logic to avoid silently returning 0 on clock errors; propagate a typed
error or use a named safe fallback with sanitized structured logging. Preserve
the existing millisecond conversion and u64 overflow handling while ensuring
expiration checks cannot treat expired OAuth tokens or MCP client secrets as
unexpired.

Line 3 makes

- Propagate autocmd option errors instead of defaulting once to false. - Log job wait() failures instead of dropping the OS error. - Document the pinned nightly-2026-08-14 toolchain in the changelog fragment (no floating channel, no cranelift claims). - Install the pinned nightly with its build target in release.yml. - Scope result_large_err to the four websocket functions instead of allowing it workspace-wide.
The scoped per-function allows surfaced further sites in closures and test helpers; the deliberately rich WebSocketAttemptError type makes the workspace-wide allow the consistent choice.

Cargo'scodegen-backendprofile key is target-independent (confirmed against the Cargo unstable-features docs and the original implementation PR — no[target.<triple>]table can carry it), so the five non-Linux jobs (Lint (Windows),Lint (macOS),Build (Windows),Test (Windows),Test (macOS)) instead get a job-levelenv: CARGO_PROFILE_DEV_CODEGEN_BACKEND: llvmoverride back to LLVM.

Cranelift stays dev-profile-only, so release binaries remain LLVM-compiled — no runtime-codegen change to what ships.linux-stable,linux-coverage,linux-bench,windows-stable,macos-stable) because switching stable→nightly changes the compilerrust-cachekeys on. One-time cost, not a regression in ci(perf): group rust-cache entries by shared-key and gate writes to main #367's cache work — the dated pin (vs. floating) is what keeps this a one-time cost rather than a daily one.-D warningsmakes that a hard CI gate), not casually.Test plan
