The -# point is just to experiment with random junk that probably won't work, so we -# can figure out what we actually do want to do internally. - -# Currently this demonstrates what seems to be a weird bug in the Windows -# kernel. If you: -# -# 0. Set up a socket so that it's not writable. -# 1. Submit a SEND poll operation. -# 2. Submit a RECEIVE poll operation. -# 3. Send some data through the socket, to trigger the RECEIVE. -# -# ...then the SEND poll operation completes with the RECEIVE flag set. -# -# (This bug is why our Windows backend jumps through hoops to avoid ever -# issuing multiple polls simultaneously for the same socket.) -# -# This script's output on my machine: -# -# -- Iteration start -- -# Starting a poll for -# Starting a poll for -# Sending another byte -# Poll for : got -# Poll for : Cancelled() -# -- Iteration start -- -# Starting a poll for -# Starting a poll for -# Poll for : got Sending another byte -# Poll for : got -# -# So what we're seeing is: -# -# On the first iteration, where there's initially no data in the socket, the -# SEND completes with the RECEIVE flag set, and the RECEIVE operation doesn't -# return at all, until we cancel it. -# -# On the second iteration, there's already data sitting in the socket from the -# last loop. This time, the RECEIVE returns immediately with the RECEIVE flag -# set, which makes sense -- when starting a RECEIVE poll, it does an immediate -# check to see if there's data already, and if so it does an early exit. But -# the bizarre thing is, when we then send *another* byte of data, the SEND -# operation wakes up with the RECEIVE flag set. -# -# Why is this bizarre? Let me count the ways: -# -# - The SEND operation should never return RECEIVE. -# -# - If it does insist on returning RECEIVE, it should do it immediately, since -# there is already data to receive. But it doesn't. -# -# - And then when we send data into a socket that already has data in it, that -# shouldn't have any effect at all! But instead it wakes up the SEND. -# -# - Also, the RECEIVE call did an early check for data and exited out -# immediately, without going through the whole "register a callback to -# be notified when data arrives" dance. So even if you do have some bug -# in tracking which operations should be woken on which state transitions, -# there's no reason this operation would even touch that tracking data. Yet, -# if we take out the brief RECEIVE, then the SEND *doesn't* wake up. -# -# - Also, if I move the send() call up above the loop, so that there's already -# data in the socket when we start our first iteration, then you would think -# that would just make the first iteration act like it was the second -# iteration. But it doesn't. Instead it makes all the weird behavior -# disappear entirely. -# -# "What do we know … of the world and the universe about us? Our means of -# receiving impressions are absurdly few, and our notions of surrounding -# objects infinitely narrow. We see things only as we are constructed to see -# them, and can gain no idea of their absolute nature. With five feeble senses -# we pretend to comprehend the boundlessly complex cosmos, yet other beings -# with wider, stronger, or different range of senses might not only see very -# differently the things we see, but might see and study whole worlds of -# matter, energy, and life which lie close at hand yet can never be detected -# with the senses we have." -
