# golang.org/issue/46347: a stale runtime/cgo should only force a single rebuild

[!cgo] skip
[short] skip


# If we set a unique CGO_CFLAGS, the installed copy of runtime/cgo
# should be reported as stale.

env CGO_CFLAGS=-DTestScript_cgo_stale=true
stale runtime/cgo


# If we then build a package that uses cgo, runtime/cgo should be rebuilt and
# cached with the new flag, but not installed to GOROOT.
# It has no install target, and thus is never stale.

env GOCACHE=$WORK/cache  # Use a fresh cache to avoid interference between runs.

go build -x .
stderr '[/\\]cgo'$GOEXE'["]? .* -importpath runtime/cgo'
! stale runtime/cgo


# After runtime/cgo has been rebuilt and cached, it should not be rebuilt again.

go build -x .
! stderr '[/\\]cgo'$GOEXE'["]? .* -importpath runtime/cgo'
