It is now tested both via cowboy_req:read_body and
via cowboy_req:cast.
Removes a bad example from the guide of body reading
with period of infinity, which does not work.
Bad chunk sizes used to be accepted and could result in
a badly parsed body or a timeout. They are now properly
rejected.
Chunk extensions now have a hard limit of 129 characters.
I haven't heard of anyone using them and Cowboy does not
provide an interface for them, but we can always increase
or make configurable if it ever becomes necessary (but
I honestly doubt it).
Also a test from the old http suite could be removed. Yay!
The 100 continue response will only be sent if the client
has not sent the body yet (at all), if the connection is
HTTP/1.1 or above and if the user has not sent it yet.
The 100 continue response is sent when the user calls
read_body and it is cowboy_stream_h's responsibility
to send it. This means projects that don't use the
cowboy_stream_h stream handler will need to handle the
expect header themselves (but that's okay because they
might have different considerations than normal Cowboy).
This is a large commit. The cowboy_req interface has largely
changed, and will change a little more. It's possible that
some examples or tests have not been converted to the new
interface yet. The documentation has not yet been updated.
All of this will be fixed in smaller subsequent commits.
Gotta start somewhere...
Along with more cowboy_req tests.
This commit also removes cowboy_req:url/1 and cowboy_req:host_url/1
in favor of the much more powerful new set of functions.
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.
