Release Notes

sebastienros/jint (Jint)

v4.9.1

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).
