4.9.1

A bug-fix release focused on async correctness, number-to-string conversion, and CLR interop edge cases.

Highlights

Async correctness

Three fixes together close a set of holes in async/await and event-loop behavior:

• Concurrent WaitForEventAsync waiters are all signaled now — previously only one waiter would wake when an event arrived (#​2427).
• Async resume now flows through control-flow statements (if/for/while/try/switch) (#​2469) and through every expression type (#​2475). Awaiting inside these constructs no longer drops state or fails to resume.

If you use Jint's async API, this release is worth picking up.

Number.prototype.toString(radix) no longer overflows

(-12345e+30).toString(2) and other large-magnitude calls used to cast directly to long, overflowing at ~9.22e18 and returning wrong digits (or throwing). The integer part now goes through BigInteger once it exceeds long range, producing the mathematically exact base-r representation for radix 2 through 36 (#​2471).

CLR interop: oversize numeric inputs

Numeric values that don't fit in the target CLR type now surface as a JavaScript RangeError instead of silently overflowing (#​2465).

Spec conformance

Updated test262 to commit 673e9bac and fixed the issues that surfaced (#​2473).

Full Changelog: sebastienros/jint@v4.9.0...v4.9.1

4.9.0

Highlights

Jint 4.9.0 is a large release focused on performance, CLR interop ergonomics, and ECMAScript spec coverage.

New language features

• Import Defer and Source Phase Imports — import defer * as ns from "mod" / import.defer() and import source x from "mod" / import.source() (TC39 proposals; 346 + 428 test262 tests pass) (#​2396)
• Import Text — import txt from "./file.txt" with { type: "text" } (TC39 Stage 3; complements the existing json / bytes paths) (#​2403)

Performance

The interpreter and built-ins got broad attention this release — see the v4.8.0 → v4.9.0 comparison table below for measured deltas.

• Custom regex engine interpreter optimized (#​2388)
• URI decode / unescape: faster and lower-allocation (#​2389)
• Array.prototype.sort / indexOf / includes / concat and sparse-array conversion optimized (#​2408)
• Lazy backing for new Array(N) plus Array.Copy fast paths for shift / unshift / splice (#​2451)
• Shape-versioned inline cache for member-expression reads (#​2412)
• FunctionEnvironment pooled per JintFunctionDefinition.State (#​2413)
• Identifier resolution: cached binding location in the slot fast path, walks skipped through empty function environments, inline small block-env slot resets (#​2416, #​2419, #​2420)
• Recursion pool + zero-alloc JsString primitive reads (#​2450)
• Avoid double-evaluating assignment bases in member access (#​2402)

CLR interop

• New opt-in Options.Interop.PreferJsPrototypeMethods() makes JS prototype methods win over CLR methods on wrapped objects (list.reverse() / list.sort() now do the JS thing on IList<T>) (#​2440)
• JS function call signatures preserved when functions are stored in Dictionary<string, object> (#​2392)
• Non-string CLR dictionary keys are now supported (#​2449)
• ThrowOnUnresolvedMember no longer throws on missing dictionary keys (#​2446)
• Fixed MissingMemberException on implicit string coercion of CLR objects (#​2439)
• CLR exceptions raised from JS now carry the originating JS source location and call stack — read via JintException.TryGetJavaScriptLocation / TryGetJavaScriptCallStack, or via JavaScriptException.Location when using CatchClrExceptions() (#​2459)

Correctness & spec coverage

• Async for-of destructuring resume bugs fixed (#​2453, #​2456)
• Module system correctness improvements (#​2395)
• Function.prototype.toString() returns the original source text for non-native functions (#​2394)
• Custom-engine regex literals now honor the prepare-time RegexTimeout (#​2457)
• Regex parsing cleanup and improved fallback-to-custom-engine detection (#​2393, #​2398)
• Many test262 exclusions dropped: Unicode SpecialCasing, calendar arithmetic, PlainMonthDay, NumberFormat precision, Hebrew leap-month, era/year consistency, locale numbering, plus a precision-aware NumberFormat path and a new ICalendarProvider extension point (#​2390, #​2407, #​2409, #​2411, #​2414, #​2423)
• Acornima parser upgraded to 1.6.1 (#​2415)

Performance: Jint 4.8.0 → 4.9.0

Same machine, same scripts, default BenchmarkDotNet settings on the v4.8.0 and v4.9.0 tags. Lower is better. Negative deltas are improvements.

Hardware: AMD Ryzen 9 5950X · Windows 11 · .NET 10.0.7 · BenchmarkDotNet 0.15.8.

Cold path — Engine.Execute(string) (parses on every call)
