And additional minor tweaks.

The option controls how much body we accept to skip for HTTP/1.1
connections when the user code did not consume the body fully.
It defaults to 1MB.

Another experimental stream handler. It enables tracing for
the connection process and any children processes based on
the matching of the request. It can be used to do ad-hoc
tracing by sending a specific header, path, method or other.
It is meant to be used both for tests and production. Some
configuration scenarios are NOT safe for production, beware.
It's important to understand that, at this time, tracing
is enabled on the scale of the entire connection including
any future request processes. Keep this in mind when trying
to use it in production. The only way to stop tracing is
by having the callback function exit (by calling exit/1
explicitly). This can be done after a certain number of
events for example. Tracing can generate a lot of events,
so it's a good idea to stop after a small number of events
(between 1000 and 10000 should be good) and to avoid tracing
the whole world.
Documentation will follow at a later time.

To obtain the local socket ip/port and the client TLS
certificate, respectively.

They are now cowboy:start_clear/3 and cowboy:start_tls/3.
The NumAcceptors argument can be specified via the
num_acceptor transport option. Ranch has been updated
to 1.4.0 to that effect.

Currently marked as experimental because it can't be tweaked
(just enabled/disabled) and because it is not documented yet.
|

|

Currently only testing handshake.
Tests that pass currently involve no request/response.
ALPN and prior knowledge support have some edge cases left to fix.
HTTP/1.1 Upgrade has not been implemented yet.

Breaking changes with previous commit. This is a very large change,
and I am giving up on making a single commit that fixes everything.
More commits will follow slowly adding back features, introducing
new tests and fixing the documentation.
This change contains most of the work toward unifying the interface
for handling both HTTP/1.1 and HTTP/2. HTTP/1.1 connections are now
no longer 1 process per connection; instead by default 1 process per
request is also created. This has a number of pros and cons.
Because it has cons, we also allow users to use a lower-level API
that acts on "streams" (requests/responses) directly at the connection
process-level. If performance is a concern, one can always write a
stream handler. The performance in this case will be even greater
than with Cowboy 1, although all the special handlers are unavailable.
When switching to Websocket, after the handler returns from init/2,
Cowboy stops the stream and the Websocket protocol takes over the
connection process. Websocket then calls websocket_init/2 for any
additional initialization such as timers, because the process is
different in init/2 and websocket_*/* functions. This however would
allow us to use websocket_init/2 for sending messages on connect,
instead of sending ourselves a message and be subject to races.
Note that websocket_init/2 is optional.
This is all a big change and while most of the tests pass, some
functionality currently doesn't. SPDY is broken and will be removed
soon in favor of HTTP/2. Automatic compression is currently disabled.
The cowboy_req interface probably still have a few functions that
need to be updated. The docs and examples do not refer the current
functionality anymore.
Everything will be fixed over time. Feedback is more than welcome.
Open a ticket!

This is a large commit.
The rfc7230 test suite adds many tests from the RFC7230 document.
Gun has been updated quite a bit recently, which broke the Cowboy
suites. This is now fixed with this commit.
A new hook onfirstrequest has been added. It was very useful during
debugging of the test suites.
The initial process code has changed a little; more changes are
expected with the switch to maps for options.

Adds a loop_handler test suite that runs all tests under HTTP, HTTPS,
SPDY each with and without the compress option enabled.
Fixes output filtering that used to filter more than it should have.
This forces us to parse the string sent by the emulator, which means
it's probably not perfect yet. But it should at least not hide errors
we want to see.
Fix a crash in the output filtering code that entirely disabled
output. Now when there is a crash the normal tty output is restored.
Handlers are now in test/handlers/ as they can be reused between
suites.
Only generate a single certificate for the whole ct run to speed
things up when we got many different test groups each needing
certificates.

Includes a variety of small changes that are a first step to
improving the test system heavily.
