golang.org/x/sync/singleflight — validation proof

Go’s own golang.org/x/sync/singleflight test suite, converted to C# by go2cs, built against the converted standard library, run under the Go-semantics test host, and compared verdict for verdict against a clean go test -json baseline of the same sources. This page is generated by the converter from that comparison, and written beside the conversion: it is not a row of go2cs’s standard-library roster.

Excluded declarations

Declarations filtered from both sides of the comparison, and therefore not claimed above: Benchmark, Fuzz and Example declarations the converted host does not execute, plus any test requiring a capability the managed runtime does not provide — a testing member the host has not implemented, or a platform behavior it provably cannot reproduce. Each is named with the capability it needs.
