This will be reintroduced in a future release once the
interface stabilizes. For the time being it will be an
internal module only.
|
|
|
|
|
|
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.
|
|
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.
|
|
|
|
This fixes the connection being dropped because of request_timeout
despite there being some active streams.
|
|
To accomplish this the code for sending the 101 response was
moved to the cowboy_http2 module.
|
|
|
|
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.
|
|
The API will be more consistent like this, and we can ensure
that duplicate cookie names are never sent.

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.

In particular the cowboy_sub_protocol is subject to change soon.
Also the cowboy_stream behavior is going to be left hidden in
this release and enabled when it becomes easier to chain them.

Also fixes a small mistake in cowboy_websocket.

The changelog had a wrong reference to an option that was updated.
`max_header_request_line_length` -> `max_request_line_length`

Only the access functions have been modified so far.

It now links to all modules found in the manual and can therefore
easily act as an index for the application.
|
|
|
|
This commit separates the documentation of the functions into
separate manual pages, with at least one example per function
and a lot more details about parameters, return values and
related functions and modules. It also includes a changelog
indicating when the function was added or changed.
The inspiration for this comes mainly from the PHP documentation
and feedback from users.

A few small revisions were made, and Erlang.mk has been updated.
|
|
Mostly useful for REST, which has a ton. This is an initial
commit, it still needs to be tested, but it's time to sleep.
|
|
Updates Cowlib to 1.1.0
|
|
Now everywhere in Cowboy when we want to stop something we return
a 'stop' tuple instead of one of the many choices depending on
context that we had before.
This particular change affects middlewares, sub protocols and
REST handlers which were using 'halt' to stop processing.
|
|
The 'shutdown' atom has a specific meaning inside OTP. We are
instead going to use 'stop' which is pretty much the equivalent
of what we actually do. 'shutdown' is now reserved for future
special processes implementation.
|
|
Wasn't following the same order as the rest of the module.
|
|
This callback was simply useless.
