2012-03-15Add an 'onrequest' hook for HTTPLoïc Hoguin
This new protocol option is a fun. It expects a single arg, the Req, and should only return a possibly modified Req. This can be used for many things like URL rewriting, access logging or listener-wide authentication. If a reply is sent inside the hook, then Cowboy will consider the request handled and will move on to the next one.
2012-03-13Do not send chunked Transfer-Encoding replies for HTTP/1.0Loïc Hoguin
Fixes compatibility issue #140 reported by @majek.
2012-02-29Tests and fixes for the generate_etag/2 callbackMagnus Klaar
The return value from the generate_etag/2 callback is expected to be a binary tagged with either weak or strong. This binary is quoted, and may be prefixed with W/ before it is set as the value of the ETag header in the response. For backwards compatibility with older handlers where the return value was expected to be a quoted binary a function has been added to parse any return values that are untagged binaries. All untagged binaries are expected to be a valid value for the ETag header.
2012-02-02Added absoluteURI supportDavid Kelly
If requests go through a proxy, they will have the original uri in the request, i.e. : GET http://proxy.server.uri/some/query/string HTTP 1.1 ... That was problematic -- cowboy_http_protocol:request didn't know what to to with the result of decode_packet applied to this, which would be something like: ``` erlang {http_request,'GET',{absoluteURI,http,<<"proxy.server.uri">>, undefined,<<"/some/query/string">>},{1,1}} ``` So, I just ignore the host, grab the path and pass into ``` erlang cowboy_http_protocol:request({http_request, Method, {abs_path, Path}, Version}, State) ``` Seems to do the trick without much effort.

2011-12-08Allow HTTP protocol upgrades to use keepaliveLoïc Hoguin
REST needed this to be allowed to chain requests on the same connection.
2011-12-07Add cowboy_http_req:set_resp_cookie/4Loïc Hoguin
Pretty much just an alias for a combination of set_resp_header and cookie.
2011-12-06cowboy_http_protocol shouldn't crash if the client sends HTTP responsesLoïc Hoguin
It was replying back the correct error, but with a crash message in the console. This patch prevents it from crashing. Fixes issue #94 reported by oribrost.
2011-12-05Add experimental Webmachine based REST protocol supportLoïc Hoguin
As with everything experimental, it probably has a lot of bugs and may not even work. Like Websocket, REST must be upgraded from a standard resource through the init/3 function. A key difference between Webmachine and Cowboy's REST protocol handler is that in Cowboy the resource has direct access to the request object. This makes a small change in a few places where you were expected to return headers or body in Webmachine and are now expected to set them directly yourself if needed (options/2, for example). Another difference is that the functions rest_init/2 will always be called when starting to process a request. Similarly, rest_terminate/2 will be called when the process completes successfully. The Cowboy REST support also includes automatic language selection, thanks to the languages_provided/2 callback. Finally, Cowboy REST expects full URIs to be given at all times, and will not try to reconstruct URIs from fragments. Note that REST requests cannot be chained (keepalive) at this time. This is a design issue in cowboy_http_protocol that will be fixed soon. Check out the source for more details. It has been designed to be very easy to read and understand so if you don't understand something, it's probably a bug. Thanks in advance for all the great bug reports, pull requests and comments you'll forward my way!
2011-11-28Add set_resp_header/3 and set_resp_body/2 to cowboy_http_reqLoïc Hoguin
These functions allow to set response headers and body in advance, before calling any of the reply functions. Also add has_resp_header/2 and has_resp_body/1 to check if the given response headers have already been set.

2011-10-20Make sure the hixie-76 websocket code works properly with proxiesLoïc Hoguin
2011-10-19Add a max_line_length to the HTTP protocolLoïc Hoguin
Allows to limit the size of request and header lines, thus preventing Cowboy from infinitely reading from the socket and never finding an end of line. Defaults to 4096 bytes.
2011-10-10Add support for loops in standard HTTP handlersLoïc Hoguin
Now init/3 can return one of the following values to enable loops: - {loop, Req, State} - {loop, Req, State, hibernate} - {loop, Req, State, Timeout} - {loop, Req, State, Timeout, hibernate} Returning one of these tuples will activate looping in the HTTP handler. When looping, handle/2 is never called. Instead, Cowboy will listen for Erlang messages and forward them to the info/3 function of the handler. If a timeout is defined, Cowboy will also close the connection when no message has been received for Timeout milliseconds. The info/3 function is defined as info(Msg, Req, State). It can return either of the following tuples: - {ok, Req, State} - {loop, Req, State} - {loop, Req, State, hibernate} The first one ends the connection, calling terminate/2 before closing. The others continue the loop. Loops are useful when writing long-polling handlers that need to wait and don't expect to receive anything. Therefore it is recommended to set a timeout to close the connection if nothing arrives after a while and to enable hibernate everywhere. Normal HTTP handlers shouldn't need to use this and as such info/3 was made optional.
2011-10-10Add {shutdown, Req} to websocket_init/3 to fail a websocket upgradeLoïc Hoguin
This change allows application developers to refuse websocket upgrades by returning {shutdown, Req}. The application can also send a reply with a custom error before returning from websocket_init/3, otherwise an error 400 is sent. Note that right now Cowboy closes the connection immediately. Also note that neither terminate/3 nor websocket_terminate/3 will be called when the connection is shutdown by websocket_init/3.
2011-10-06Allow HTTP handlers to skip the handle/2 step in init/3Loïc Hoguin
You can now return {shutdown, Req, State} from Handler:init/3 to skip the handle/2 step. Also allow init/3 function to send responses.
2011-10-06Merge branch 'hybi-framing-fix' of https://github.com/smarkets/cowboyLoïc Hoguin
2011-10-06Close the connection when the application sends Connection: closeLoïc Hoguin
Now Cowboy checks headers sent to the client for the 'Connection' header value, parses it, and checks whether it contains a 'close' or 'keep-alive' value. It makes sure to close or keep the connection alive depending on the value found there, if any. Also change chunked replies to not close the connection by default unless the application requests it.
2011-10-04Do not send a 408 response if the Request-Line wasn't fully receivedLoïc Hoguin
The server should not send a response if there wasn't at least the beginning of a request sent (the Request-Line).
2011-10-03Fix byte-by-byte Websocket handlingHunter Morris
If the websocket frame handling code in cowboy_http_websocket receives only 1 byte at a time, it fails with a badmatch in cowboy_http_websocket:websocket_data/4. This commit fixes the problem and introduces a test of the correct behaviour.
2011-09-22Add a test for websocket hibernate + timeout and fix this use caseLoïc Hoguin
The issue was that we were calling erlang:hibernate before a receive .. after .. end call. Erlang hibernates the process before reaching the receive instruction and we therefore couldn't enter the after clause when hibernating. This is now fixed by using erlang:send_after instead and receiving that message instead of using an after clause.
2011-09-14'Host' header is optional in HTTP/1.0Loïc Hoguin
Krishnamurthy, Kristol, Mogul: "Key Differences between HTTP/1.0 and HTTP/1.1", "Internet address conservation". http://www8.org/w8-papers/5c-protocols/key/key.html Fixes issue #35 reported by Alex Kropivny.
2011-09-13Reset the max number of empty lines between keepalive requestsLoïc Hoguin
Fixes issue #47.
2011-08-23Add WebSocket drafts 7, 8, 9 and 10 implementationLoïc Hoguin
The implementation is only partial for now but should work for all browsers implementing it.
2011-06-27do not send ports 80 and 443 - browsers get madSteven Gravell
Browsers get mad that the returned location address is not the same as what they sent, since the :(80|443) is stripped. Add a simple eunit test due to existing ct websockets tests not covering this case.
2011-05-08Add chunked reply support.Loïc Hoguin
Send the status line and headers using cowboy_http_req:chunked_reply/3, and individual chunks with cowboy_http_req:chunk/2.
2011-05-05Add headers_huge test, demonstrating issue #3 is fixed.Loïc Hoguin
The previous commit switching to raw recv + erlang:decode_packet/3 works around the OTP bug regarding headers size in http recv.
2011-05-05Switch the HTTP protocol to use binary packets instead of lists.Loïc Hoguin
The server now does a single recv (or more, but only if needed) which is then sent to erlang:decode_packet/3 multiple times. Since most requests are smaller than the default MTU on many platforms, we benefit from this greatly. In the case of requests with a body, the server usually read at least part of the body on the first recv. This is bufferized properly and used when later retrieving the body. In the case of pipelined requests, we can end up reading many requests in a single recv, which are then handled properly using only the buffer containing the received data.
2011-05-04Add cowboy_http_req:port/1.Loïc Hoguin
Returns the port given in the Host header if present, otherwise the default port of 443 for HTTPS and 80 for HTTP is returned.
2011-04-17ct: Throw garbage at the server then check if it's still up.Loïc Hoguin
Basically: cat /dev/urandom | nc host port Only run this test if cat and nc are available.
2011-04-14Initial draft-hixie-thewebsocketprotocol-76 support.Loïc Hoguin
2011-04-14Fix a bug where dupe headers were sent in cowboy_http_req:reply/4.Loïc Hoguin
Now the server defines default headers that can be overwritten by the handler simply by passing them to the reply/4 function. Default headers include, for now, Connection and Content-Length headers. Note that it isn't enough to change the Connection header to close a keep-alive connection server-side.
2011-04-10ct: Add a test for requests pipelining.Loïc Hoguin
2011-04-09ct: Add a test for \n which throws an error 400.Loïc Hoguin
2011-04-09Limit the number of empty lines to allow before the request-line.Loïc Hoguin
Defaults to 5. Prevents someone from indefinitely sending empty lines.
