Re: [PATCH] tests: commandhelper: Accept POLLNVAL on macOS

commandhelper hangs indefinetely in poll() on macOS on commandtest test2

and later because POLLNVAL is returned on revents for input file descriptor opened from /dev/null, i.e this hangs: $ tests/commandhelper < /dev/null BEGIN STDOUT BEGIN STDERR ^C But it works fine with regular stdin: $ tests/commandhelper <<< test BEGIN STDOUT BEGIN STDERR test test END STDOUT END STDERR The issue is mentioned in poll(2): BUGS The poll() system call currently does not support devices. With the change all 28 cases in commandtest pass.
