I'm trying to write a bunch of data to a process, then read out the result. Replaced the process here with `cat -` because that's close enough.
function bloop(size) data = "f" ^ size print("start") (pout, pin, p) = readandwrite(`cat -`) print("write") write(pin, data) print("flush") flush(pin) print("close") close(pin) print("read") output = read(pout) print("close") close(p) println() output end If `size <= 146944`, this succeeds. If `146944 < size <= 147456`, Julia blocks forever at the `read` call in a `kevent` system call. If `size > 147456`, Julia blocks forever at the `write` call in a `write` system call. How can I make this work?
