If a loop handler sent a response (e.g. cowboy_req:chunked_reply/2,/3)
and then returns {loop, Req, HandlerState, hibernate} it
would have a {cowboy_req, resp_sent} message in its message queue. This
message would cause the process to immediately awaken, so it is flushed
before hibernation.

It is sometimes important to make a socket passive as it was initially
and as it is expected to be by cowboy_protocol, right after we've done
with loop handling.
|
|
We now read from the socket to be able to detect errors or TCP close
events, and buffer the data if any. Once the data receive goes over
a certain limit, which defaults to 5000 bytes, we simply close the
connection with an {error, overflow} reason.

This should have been done a *long* time ago, back when I initially
added Websocket support. This is the first part of two in improving
loop handler support with regards to socket closure.
Reason may include: {normal, shutdown} for the most normal shutdown,
{normal, timeout} for a loop handler timeout shutdown, or {error, _}
if an error occured.

Middlewares allow customizing the request processing.
All existing Cowboy project are incompatible with this commit.
You need to change `{dispatch, Dispatch}` in the protocol options
to `{env, [{dispatch, Dispatch}]}` to fix your code.
