PerryTS/perry v0.5.509

on GitHub

Highlights

• #447 / #448 / #451 collapsed into a single 3-line ABI fix (v0.5.508): js_object_set_field was declared with a DOUBLE value arg but the runtime takes JSValue (u64). On AArch64 / x86_64 SysV / Win64 these use disjoint register classes — values landed in xmm0/d0 while the runtime read garbage from rdx/x2. With it fixed, async generators, *[Symbol.iterator](), for-await-of, await using, Promise.allSettled / .any / .withResolvers, queueMicrotask, Array.fromAsync, and JSON.stringify with toJSON all unblocked at once. Two independent investigation agents reached the same diagnosis simultaneously.
• perry/tui v1 complete (#347 / #358): native readline with raw-mode + keypress + SIGWINCH, isatty + columns/rows, Taffy flexbox layout, Spinner / Input / List / Select / TextArea widgets, no-flicker proof.
• HarmonyOS / --target harmonyos significantly improved: Mango welcome-screen now renders on OHOS; #395 / #399 / #400 / #408 / #410 / #413 closed.
• Performance: image_convolution workload now beats Rust (377 ms vs 414 ms) after a chain of i32-shadow + static-trip-count unroll + channel-vector SIMD landings; json_pipeline_full matches Node and beats baseline by 30% after the GC bytes-trigger fix; closure-caching + Map/Set side-tables + GC perf rework cut ECS workload time substantially.

Features

• #358 perry/tui Phase 1–4.5: native engine, state + input + run loop, Taffy flexbox layout, full v1 widget set (Spacer, ProgressBar, Spinner, Input, List, Select, TextArea, …)
• #347 readline / TTY: line-buffered readline.createInterface, process.stdin.setRawMode, keypress events, isatty, columns/rows, SIGWINCH
• #408 codegen-arkts: tracks procedural widget mutations on locals
• #427 i18n: translations for de / ja / ko / zh-CN

Performance

• image_convolution perf chain: i32-shadow init path → static-trip-count for-loop unroll → channel-vector SIMD reduction → strict-i32-bounded clamp gate. Now 377 ms vs Rust's 414 ms (was ~470 ms pre-chain).
• json_pipeline_full: GC bytes-trigger bump after gc-suppressed parse → 30% faster than baseline; matches Node, ~1.6× behind Rust/Bun.
• ECS workload (@codehz/ecs simple demo): closure-caching by func_ptr + capture-bits, single-slot per-func cache, Map/Set side-tables to PtrHasher, MAP/SET/BUFFER registries to PtrHasher, GcHeader byte-load fast pre-filter, vtable IC for method dispatch, skip method-name string alloc.
• GC: bytes-trigger threshold-based (not malloc-count), shadow-stack TLS coalesced, ValidPointerSet split arena+malloc + driftsort sort, sweep walk with fold-in age bump.
• Inliner widening: This-receiver inlining, Let-init-Call inlining, closures, cross-module method inlining for symbol-stable methods, cross-module ExternFuncRef.
• Object literal: shape-cache fast path with packed-keys global. Map/Set: direct-entries / direct-element fast path for for-of. Closure: fast-path for non-capturing + FuncRef wrappers.

Infrastructure

• Honest-bench output correctness gate (#441)
• ECS perf case study committed
• cargo test workspace-exclude list now correct on macOS host (#453)
• 6 previously skip-listed test_async* tests un-skipped after #447 close (v0.5.509)

Migration notes

No breaking API changes. The ABI fix in v0.5.508 is purely internal (codegen ↔ runtime calling convention); user code is unaffected.
