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.
2011-05-05Switch 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.
2011-04-30Remove the next_request function always matching its first clause.Loïc Hoguin
2011-04-18Remove the include/types.hrl file.Loïc Hoguin
2011-04-18Move the dispatcher related types into cowboy_dispatcher.Loïc Hoguin
2011-04-18Rename dispatch() into dispatch_rules().Loïc Hoguin
2011-04-18Use the inet:socket() type instead of the user-defined one.Loïc Hoguin
2011-04-12Fix a pattern matching bug in cowboy_http_protocol:handler_init/2.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.
2011-04-07Don't crash on errors while receiving headers; throw an error 500 instead.Loïc Hoguin
The server shouldn't crash the request process when we have an error while receiving headers. A case where this could happen is if the header line is too long. See also bfrog's report on ticket #3 on github.
2011-04-05Don't automatically retrieve the peer information for the 'OPTIONS' method.Loïc Hoguin
2011-04-05Handle properly the default Connection value for HTTP/1.0.Loïc Hoguin
Fixes a bug reported by evaxsoftware on IRC.
2011-03-27Use a more efficient variant of string:to_lower to improve performance.Loïc Hoguin
After much testing and experimentation of all kinds I find lists to be both faster and using less memory than binaries for request-line and headers handling. This is more than likely due to the fact that headers are very short and thus do not benefit from the advantages of refc binaries, meaning they're copied, just like lists. The memory usage discrepancy is still a mystery for the most part, although the hoops needed to perform operations on the binaries are probably responsible for the extra memory use. I'm thus giving up on trying to use binaries for request-line and headers. Instead, this commit improves performances even more to the lists code, making lists 5% faster than binaries. Lists are easier to work with too, so I guess it's all a big win for everyone. Of course the request body is still read as a binary, we're using the binary type where it performs best.
2011-03-27Match early in connection_to_atom for a small performance improvement.Loïc Hoguin
2011-03-22Allow Handler:init/3 to request a protocol upgrade.Loïc Hoguin
2011-03-22Forward transport and protocol name to Handler:init.Loïc Hoguin
2011-03-22Explicitly ignore the return value of cowboy_http_req:reply in error_response.Loïc Hoguin
2011-03-21Fix spec for cowboy_http_protocol:init/3.Loïc Hoguin
2011-03-21Introduce cowboy_http_req:body/1 to read the full request body.Loïc Hoguin
2011-03-21Make sure error_response always returns ok.Loïc Hoguin
2011-03-21Add specs to ensure_response and change the clauses order.Loïc Hoguin
2011-03-21Skip the request body if it hasn't been read by the handler.Loïc Hoguin
2011-03-20Ensure a response is sent when the handler doesn't reply anything.Loïc Hoguin
2011-03-20Move the error response code into a separate function.Loïc Hoguin
2011-03-20Make sure we can only reply to an HTTP request inside Handler:handle.Loïc Hoguin
Of course since requests are a record the response state can be explicitly overriden, but standard use prevents errors by making sure only one reply is sent.
2011-03-20Lazy-retrieve the peer name and port to avoid wasting time each request.Loïc Hoguin
2011-03-20Change a @todo for Handler:init possible return values.Loïc Hoguin
2011-03-20Rename a variable in cowboy_http_protocol for clarity.Loïc Hoguin
2011-03-20Allow code reloading inside the cowboy_http_protocol module during keep-alive.Loïc Hoguin
2011-03-20Default the connection to keep-alive on HTTP/1.1 and close on 1.0.Loïc Hoguin
2011-03-20Save the raw path string in the request.Loïc Hoguin
2011-03-19Save the raw host string in the request.Loïc Hoguin
2011-03-19Protect the calls to the handler using catch.Loïc Hoguin
* Handler:init shouldn't reply anything; send an error 500. * Handler:handle may have sent something to the client; close the socket. * Handler:terminate failed to clean itself up. Close the socket.
2011-03-19Add support for the '*' path.Loïc Hoguin
Mostly used by the following request: OPTIONS * HTTP/1.1
2011-03-19Rewrite the dispatcher to take a list of host each having a list of paths.Loïc Hoguin
* 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.
2011-03-19Ignore all extra Host values sent in the request.Loïc Hoguin
2011-03-19Reply with error 501 on all non absolute path URIs for now.Loïc Hoguin
2011-03-19Reply with error 400 on all bad Request-Lines received.Loïc Hoguin
2011-03-19Ignore empty lines when expecting the Request-Line.Loïc Hoguin
In the interest of robustness, servers SHOULD ignore any empty line(s) received where a Request-Line is expected. In other words, if the server is reading the protocol stream at the beginning of a message and receives a CRLF first, it should ignore the CRLF.
2011-03-19Comparisons of host names MUST be case-insensitive.Loïc Hoguin
2011-03-19Notify the client that we're closing the connection after the error reply.Loïc Hoguin
2011-03-18Move the reply function to cowboy_http_req.Loïc Hoguin
2011-03-18Introduce Handler:terminate to cleanup the handler's state.Loïc Hoguin
2011-03-18Handler:init/2 should also return the Request in case it changed.Loïc Hoguin
2011-03-18Introduce Handler:init/2 for initializing the handler state.Loïc Hoguin
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.
2011-03-17Remove a superfluous terminate call in error_terminate.Loïc Hoguin
2011-03-17Run the dispatcher as early as possible to quickly dismiss 404 errors.Loïc Hoguin
2011-03-17Initial commit.Loïc Hoguin
