But it also replaces any cv_status returned by __wait_until_impl into a cv_status::no_timeout, is that intentional ? IMHO it should store the returned status and return it unchanged if not timeout.But __wait_until_impl can only return timeout or no_timeout: enum class cv_status { no_timeout, timeout };I didn't want to check __wait_until_impl cause my remark was more general. But if enum only has 2 entries it sounds safe enough indeed.
It's a scoped enumeration, so all the values of its underlying type are valid values of the enumeration type i.e. somebody could do cv_status{413} and it would be valid. But __wait_until_impl doesn't do that, and never will, and wait_until is required to only return timeout or no_timeout, so Mike's patch would still be correct anyway even if __wait_until_impl did something dumb :-)
