v0.5.1116

Highlights

v0.5.1112

First tagged distribution release since v0.5.1028 — folds in 1198 commits (852 fixes, 42 features, plus tests/docs/refactors). This tag is a clean version-bump checkpoint over a fully CI-green main.

Highlights

• Broad Node.js builtin parity push: crypto/webcrypto, http/http2/Agent socket pooling, zlib (sync + streaming + Brotli), child_process (streaming spawn, fork + V8-IPC, promisify), util, process, punycode, url, worker_threads, stream (web codec constructors, iterator helpers), dgram, cluster, path, vm.
• Reflective builtin-prototype brand checks (#3662 family): Function.prototype.apply/call/bind/toString, primitive prototypes (Number/Boolean/Symbol/BigInt), collection prototype methods, namespace member reflection.
• Typed-array prototype + constructor coverage (join/slice/reverse/fill/subarray, RangeError validation, proto accessors).
• Generational-GC evacuation + async-resume fixes.

Features (selected)

• compile: module-graph tree-shaking / DCE for compilePackages.
• Self-hosted build-time precompile() — Perry runs its own codegen with no node/V8.
• node:zlib complete sync codec parity + Transform-stream objects + Brotli.
• node:child_process async spawn reactor, fork + IPC, exec error/encoding parity.
• node:http Agent socket pooling + createConnection/createSocket on the request path.
• Generator function expressions, yield* operand iteration, class [Symbol.iterator]/[Symbol.asyncIterator] via member access.
• perry/ui: continuous pointer/key events, onFrame/cancelFrame display-link callbacks; perry/audio cross-platform sound; GTK4 live CameraView.
• Object.getOwnPropertyDescriptors, dynamic-import directory-glob template specifiers.

Fixes

• 852 fixes across codegen, HIR lowering, runtime, and stdlib — Node export hygiene, dispatch correctness, stream construction paths, handle-deref segfaults, and large swaths of the TypeScript/Node compatibility roadmap (#793).

See CHANGELOG.md for the full per-version detail.

v0.5.1028

First tag in the v0.5.1025 → HEAD window — also implicitly ships the v0.5.1026 and v0.5.1027 work that never got their own tags. See CHANGELOG.md for the full per-PR history.

Highlights (v0.5.1025 → v0.5.1028):

• node:timers epic (#1213, 6 PRs in v0.5.1026): node:timers/promises, numeric-id clear*, namespace import, ref() typeof, Symbol.dispose, global setImmediate/clearImmediate
• node:perf_hooks fan-out (10 PRs in v0.5.1026): typeof methods, globalThis.performance identity, nodeTiming, toJSON, clearResourceTimings, structured-clone detail, observer-arg + buffered + throw cases
• Windows fixes (v0.5.1027): #1542 black areas after App window resize; restored Windows source build (cp.rs set_path_times cfg-gating)
• Compile / lockdown / dynamic-import (this batch): --trace/--focus flags (#1738); lockdown #503 allows ns[dynamicKey].staticMember (#1741); literal node: builtin import() (#1742); Blob/URL globals trigger http-client (#1747); win32 path.normalize/basename/toNamespacedPath edges (#1749)
• Major parallel streams: v0.5.1026 closes #1424 (lazy-tape reviver SIGSEGV); #1429 GC unsafe-zone guards for fastify/hyper; v0.5.1027 + this batch include lockdown #503 polish; #1718-era HTTP trailers + WebSocket upgrades + Buffer encodings (#1709); native .js/.cjs + require() compile (#1711); URLSearchParams iteration (#1668); Web Streams inline property reads (#1670); fetch Request.text()/.json()/.arrayBuffer() (#1688); --debug-symbols retention (#1663); GC barrier on Promise pointer stores (#1715); regex dynamic dispatch (#1731); …

test_async_local_storage_context (#1423) remains skip-listed (.enterWith/.exit pending, sibling slice of #788/#789).

v0.5.1025

Hotfix on top of v0.5.1024, unblocking the gate failures from that release.

simctl iOS: find_geisterhand_lib no longer falls back to host target/release/<lib>.a when a cross-compile target is set — that fallback was producing macOS .a archives in iOS-simulator link commands AND masking the geisterhand auto-build trigger so the cross-target libs never got built.

Parity gate (2 new failures triaged):

• #1423 test_async_local_storage_context — AsyncLocalStorage.enterWith / .exit aren't implemented end-to-end (sibling slice of #788 #789). Skip-listed.
• #1424 test_json_lazy_reviver — JSON.parse(blob, reviver) on a lazy-tape top-level array exits before any output. Skip-listed.

compile-smoke memory ceiling restore — PR #1422 (dec43e27) put the 290/315 MB test_memory_json_churn ceiling back after #1324 reverted it.

Also folds in the post-v0.5.1024 work that landed on main: #1365 crypto.generateKeyPairSync (RSA + EC) (#1418).

See CHANGELOG.md.

v0.5.1024

Release sweep — 26 PRs rolled up post-v0.5.1023.

Highlights:

• node:crypto gap-fixes — randomInt, timingSafeEqual, getHashes / getCiphers, sha224 / sha384, base64 digest, Buffer hash input, no-arg digest() typed as Buffer, pbkdf2Sync digest argument, scryptSync (PRs #1386 #1393 #1394 #1402 #1405)
• node:perf_hooks native impl — performance + User Timing + PerformanceObserver + granular node-suite (#1321 #1328 #1342)
• #1090 GC checkpoint runtime work (#1324)
• #1311 geisterhand on iOS — --target ios builds + links inspector; SecureField registered; perry-stdlib auto-included (#1316 #1383 #1384 #1385)

See CHANGELOG.md for the full per-PR rollup.

v0.5.1022

Sequel to v0.5.1021 + binary-size baseline refresh.

• #1246 follow-up: perry-ui-gtk4 image.rs now reaches resolve_asset_path at its new home crate::ffi::layout::resolve_asset_path (left private when #1246 split the file). Surfaced on the v0.5.1020 release-packages linux-aarch64-gnu build with error[E0425]: cannot find function resolve_asset_path in the crate root — that failure fail-fast-cancelled four other matrix builds and skipped every publish job (winget / homebrew / npm / apt / apt-repo).
• binary-size baseline refresh: 566 patches of intentional product delta since the v0.5.455 (7fd1c8b3) baseline pushed perry +22.6% / libperry_runtime +34.0% / libperry_stdlib +6.5%. Same shape as the v0.5.455 refresh — the 15% per-release threshold is for incremental drift, not multi-release catch-up. New baseline captured from f7aaed1a Regression Check macos-14 run. Production binaries are stripped by the linker; the .a / .bin sizes the job measures are unstripped release-build artefacts used as a regression-trend signal, not a deployment-size measurement.

Closes the v0.5.1020 release-packages regression. See CHANGELOG.md.

v0.5.1021

Hotfix on top of v0.5.1020: restore perry-ui-gtk4 image.rs resolve_asset_path access after #1246's file-split refactor moved the function into ffi::layout and left it private. The v0.5.1020 release-packages run (#26249481496) failed on linux-aarch64-gnu with E0425 and fail-fast cancelled the publish pipeline.

Two-line fix in #1298. Local cargo check + PR CI green. See CHANGELOG.md.

v0.5.1020

Pre-release tag of current main. Closes the 5 parity failures + memory-ceiling regression from v0.5.1019:

• #1273 Buffer.from(str, encodingVar) HIR routing (#1282)
• #1274 EventEmitter numeric/object payload args returned NaN — perry-ext-events still had the legacy (arg: f64) ABI from before PR #1186's NA_VARARGS switch (#1289)
• #1275 TextEncoder mojibake (#1282)
• #1276 console.table spurious Values column on array-of-arrays (#1282)
• #1277 Closed as misdiagnosis (Perry's Instant::now() is correct; the apparent timer divergence is AOT-vs-interpreted speedup on a DCE-able loop)
• #1278 console.trace stack-format kept as tracked categorical, skip-listed
• memory test_memory_json_churn Ubuntu RSS budget widened to 290/315 MB to cover #1090 GC rework grace (#1286)

Plus #1088 host-embed staticlib linkdeps sidecar, #1122 iOS UIButton layer.backgroundColor, #1129/#1136 iOS heap-pointer guards, #1162 node:path.win32, #1193 cheerio chains, #1205/#1206/#1210/#1211 node:buffer parity, #1225 Buffer.from shared identity, #1280 App windowState, #1288 jsonwebtoken rust_crypto for ios setup, #1291 android setup keystore validation, plus granular tty + events parity suites.

See CHANGELOG.md for the full rollup.

v0.5.1019

Pre-release tag of current main. Highlights since v0.5.1011: #1088 host-embed --output-type staticlib + Event Loop FFI, #1248/#1249 inspect.custom + nested multi-line break, #1236 aws-lc-sys 0.41 (Linux poly_Rq_mul fix), and the http options-object regression from #1123/#1124 should be addressed in this batch.

v0.5.1011

Pre-release tag of current main. Highlights since v0.5.1008: #1131/#1132 Socket.write(string) + arrow-param tag scope, #1123/#1124 net.createServer + http Buffer bodies end-to-end, #1106 GC telemetry + dirty-page remembered scanning.
