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.
make docs: generate Markdown and man pages in doc/
make install-docs: install man pages to be usable directly
Docs are generated from the ezdoc files in doc/src/.
This change makes the dependency on quoted optional
by adding a minimal urldecode function to cowboy.
A protocol option for setting the urldecoding function
has been added to the cowboy_http_protocol module.
The default value for this option is set to be
equivalent to the default settings for quoted.
{fun cowboy_http:urldecode/2, crash}
A note has been added in the README to document
how to use quoted instead of this function.
A field to store this option value has been added
to the state record in the cowboy_http_protocol
module and the http_req record in include/http.hrl
Functions that previously used quoted:from_url/1
has been updated to require an equivalent function
in addition to the previously required arguments.
This change removes a C compiler from the build
requirements of cowboy. It also removes the requirement
to cross compile the code if the target arch/OS
is different from the arch/OS used to build it.
Also sends a message 'shoot' that can be received by the protocol
to make sure Cowboy has had enough time to fully initialize the
socket. This message should be received before any socket-related
operations are performed.
WebSocket request connections are now moved from the pool 'default'
to the pool 'websocket', meaning we can have a lot of running
WebSockets despite having a low 'max_connections' setting.
Improves the readability of websocket handler code by having
two functions: websocket_handle/3 handles the packets received
from the socket, removing the tuple construct that was otherwise
needed, so only websocket_handle(Data, Req, State) is needed now;
websocket_info/3 handles the messages that the websocket handler
process received, as websocket_info(Info, Req, State).
Both functions return values are handled identically by Cowboy
so nothing changes on that end.
As requested by many people on IRC Cowboy is now a proper OTP application
to support soft code upgrades. It should also be easier to start and stop
listeners now using cowboy:start_listener/6 and cowboy:stop_listener/1.
* Cowboy isn't an OTP application anymore; just a supervisor.
* All processes started by Cowboy are now anonymous.
* All processes related to a listener are now part of its supervision tree.
* Makes more sense to parse the host only once instead of for each path.
* Allows proper handling of: If the host is not a valid host on the server,
the response MUST be a 400 (Bad Request) error.
We need an init function in order to process upgrade instructions
for protocols like WebSockets, but also to request an active receive
mode for long-polling connections, both of which will be implemented
at a later time.
