When the request process exits with a {request_error, Reason, Human}
exit reason, Cowboy will return a 400 status code instead of 500.
Cowboy may also return a more specific status code depending on
the error. Currently it may also return 408 or 413.
This should prove to be more solid that looking inside the stack
trace.

This will result in no data being sent. It's simply easier to
do this than to have to handle 0 size cases in user code.

The Cowboy behavior has changed a little and gives more
accurate error responses now. And in some cases, successes.

They have equivalents in req_SUITE.
|
|
|
|
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.

Introduces the new stream_handler_SUITE test suite. More cases
will be added later on.
|
|
This option allows customizing the compacting of the Req object
when using Websocket. By default it will keep most public fields
excluding headers of course, since those can be large.

h2spec must be preinstalled on the machine and its location
pointed at by the H2SPEC environment variable.
|
|
Existing tests pass. A number of things remain to be done.
Has only been tested with Gun so far. Feedback welcome!

The inactivity timeout is used to close the connection in the absence of
any data from the client.
Since this is not part or the rfc7540 spec, a new http2_SUITE module has
been created with a test for the inactivity_timeout.
|
|
This fixes the connection being dropped because of request_timeout
despite there being some active streams.
|
|
|
|
|

These tests cover frame sizes. It's mostly edge cases for sure
(ie misbehaving clients and us having to reject them properly).
I had these almost ready for a long time, so I'm glad I can
push them out.
This requires updating Cowlib too (we currently track master).
|
|
Maps make more sense because the keys are unique.
|
|
The Opts value is put last, to be more consistent with the
rest of the cowboy_req module.
Additionally a test handler was fixed which reduced the number
of errors in http_SUITE.

Before this commit we had an issue where configuring a
Websocket connection was simply not possible without
doing magic, adding callbacks or extra return values.
The init/2 function only allowed setting hibernate
and timeout options.
After this commit, when switching to a different
type of handler you can either return
{module, Req, State}
or
{module, Req, State, Opts}
where Opts is any value (as far as the sub protocol
interface is concerned) and is ultimately checked
by the custom handlers.
A large protocol like Websocket would accept only
a map there, with many different options, while a
small interface like loop handlers would allow
passing hibernate and nothing else.
For Websocket, hibernate must be set from the
websocket_init/1 callback, because init/2 executes
in a separate process.
Sub protocols now have two callbacks: one with the
Opts value, one without.
The loop handler code was largely reworked and
simplified. It does not need to manage a timeout
or read from the socket anymore, it's the job of
the protocol code. A lot of unnecessary stuff was
therefore removed.
Websocket compression must now be enabled from
the handler options instead of per listener. This
means that a project can have two separate Websocket
handlers with different options. Compression is
still disabled by default, and the idle_timeout
value was changed from inifnity to 60000 (60 seconds),
as that's safer and is also a good value for mobile
devices.

Also finish implementing the relevant test, getting rid of todos.
|
|
A bit late but at least removes a todo.

... instead of hard-coding "make".
First, we check the value of `$MAKE`. If it's unset, we look for `gmake`
in the `$PATH`. If it's missing, we assume it's `make`.
This fixes the testsuite where GNU Make is installed as `gmake`.
|

If cowboy_static is initialized with `{priv_file, ...}` or `{priv_dir,
...}`, it is now able to read files from Erlang application .ez
archives.
When serving a file from an archive, the #file_info{} comes from the
archive, not the contained file, except for the size and type. The
erl_prim_loader module is used to read the latter's #file_info{} and the
actual file content (ie. sendfile(2) is not used in this case).
|
|
Currently marked as experimental because it can't be tweaked
(just enabled/disabled) and because it is not documented yet.
|
|
|
|
|
|
Putting them in the correct test suite, with the proper
documentation etc.
|
|
This commit changes Cowboy to follow RFC6585.

|
|
Correct expected return type from `no_call` to `undefined` in
if_modified_since when last_modified callback is not defined. Add an
http_SUITE test to catch regressions.
|
|
|
|
|
|
After the switch to Websocket, we are no longer in a request/response
scenario, therefore a lot of the cowboy_req functions do not apply
anymore.
Any data required from the request will need to be taken from Req
in init/2 and saved in the handler's state.
|
|
|
|
The option for enabling Websocket compression has been
renamed. Previously it was shared with HTTP compression,
now it's specific to Websocket. The new option is named
'websocket_compress'.
