2015-02-17Fix reply/4 specYakov
There is wrong -spec of reply/4 function 3rd parametr type must be same as [#http_req spec](https://github.com/ninenines/cowboy/blob/master/src/cowboy_req.erl#L140)
2015-02-16Do not send empty chunksLoïc Hoguin
User code may sometimes send an empty value which gets understood by the client as being the end of the stream while this was not intended. Ignoring empty values allow making sure the stream isn't ended by mistake.
2015-02-04Use cowlib for parsing headers; remove cowboy_httpLoïc Hoguin
2015-02-03Use cowlib masterLoïc Hoguin
2014-10-04Reverse the order of arguments of match_* functionsLoïc Hoguin
Wasn't following the same order as the rest of the module.
2014-10-01Req#http_req.peer can be 'undefined'; update spec accordinglyAndrew Houghton
2014-09-26Unify the init and terminate callbacksLoïc Hoguin
This set of changes is the first step to simplify the writing of handlers, by removing some extraneous callbacks and making others optional. init/3 is now init/2, its first argument being removed. rest_init/2 and rest_terminate/2 have been removed. websocket_init/3 and websocket_terminate/3 have been removed. terminate/3 is now optional. It is called regardless of the type of handler, including rest and websocket. The return value of init/2 changed. It now returns {Mod, Req, Opts} with Mod being either one of the four handler type or a custom module. It can also return extra timeout and hibernate options. The signature for sub protocols has changed, they now receive these extra timeout and hibernate options. Loop handlers are now implemented in cowboy_long_polling, and will be renamed throughout the project in a future commit.
2014-09-23Breaking update of the cowboy_req interfaceLoïc Hoguin
Simplify the interface for most cowboy_req functions. They all return a single value except the four body reading functions. The reply functions now only return a Req value. Access functions do not return a Req anymore. Functions that used to cache results do not have a cache anymore. The interface for accessing query string and cookies has therefore been changed. There are now three query string functions: qs/1 provides access to the raw query string value; parse_qs/1 returns the query string as a list of key/values; match_qs/2 returns a map containing the values requested in the second argument, after applying constraints and default value. Similarly, there are two cookie functions: parse_cookies/1 and match_cookies/2. More match functions will be added in future commits. None of the functions return an error tuple anymore. It either works or crashes. Cowboy will attempt to provide an appropriate status code in the response of crashed handlers. As a result, the content decode function has its return value changed to a simple binary, and the body reading functions only return on success.

2014-07-14Support ad-hoc keep-alive for HTTP/1.0 ClientsFred Hebert
Only go for keep-alive if they submit a 'connection: keep-alive' header in the request, keep behaviour the same otherwise. The new RFC 7230 (http://tools.ietf.org/html/rfc7230#section-6.3) states: If the received protocol is HTTP/1.0, the "keep-alive" connection option is present, the recipient is not a proxy, and the recipient wishes to honor the HTTP/1.0 "keep-alive" mechanism, the connection will persist after the current response; Even though clients are discouraged from doing so in Appendix A.1.2 (http://tools.ietf.org/html/rfc7230#appendix-A.1.2)

2014-07-12Reply with 400 on header parsing crashLoïc Hoguin
This is a first step to improve the HTTP status codes returned by Cowboy on crashes. We will tweak it over time. Also fixes a small bug where two replies may have been sent when using loop handlers under rare conditions.
2014-06-03Add a return value to onresponse hook to override status/headersLoïc Hoguin
This would allow us to override them without messing up the body, and would make it usable with the static file handler for example. Experimental at this point.
2014-06-02Add request body reading optionsLoïc Hoguin
The options were added to allow developers to fix timeout issues when reading large bodies. It is also a cleaner and easier to extend interface. This commit deprecates the functions init_stream, stream_body and skip_body which are no longer needed. They will be removed in 1.0. The body function can now take an additional argument that is a list of options. The body_qs, part and part_body functions can too and simply pass this argument down to the body call. There are options for disabling the automatic continue reply, setting a maximum length to be returned (soft limit), setting the read length and read timeout, and setting the transfer and content decode functions. The return value of the body and body_qs have changed slightly. The body function now works similarly to the part_body function, in that it returns either an ok or a more tuple depending on whether there is additional data to be read. The body_qs function can return a badlength tuple if the body is too big. The default size has been increased from 16KB to 64KB. The default read length and timeout have been tweaked and vary depending on the function called. The body function will now adequately process chunked bodies, which means that the body_qs function will too. But this means that the behavior has changed slightly and your code should be tested properly when updating your code. The body and body_qs still accept a length as first argument for compatibility purpose with older code. Note that this form is deprecated and will be removed in 1.0. The part and part_body function, being new and never having been in a release yet, have this form completely removed in this commit. Again, while most code should work as-is, you should make sure that it actually does before pushing this to production.

2014-02-06Add and document the new multipart codeLoïc Hoguin
The old undocumented API is removed entirely. While a documentation exists for the new API, it will not be considered set in stone until further testing has been performed, and a file upload example has been added. The new API should be a little more efficient than the old API, especially with smaller messages.

2013-11-09Remove an unnecessary clause in cowboy_req:body/2Loïc Hoguin
2013-11-08Add a workaround to disable chunked transfer-encodingAdrian Roe
This is an undocumented workaround to disable chunks when using HTTP/1.1. It can be used when the client advertises itself as HTTP/1.1 despite not understanding the chunked transfer-encoding. Usage can be found looking at the test for it. When activated, Cowboy will still advertise itself as HTTP/1.1, but will send the body the same way it would if it was HTTP/1.0.
2013-11-08Optimize query string parsingLoïc Hoguin
* Parsing code was moved to cowlib: cowboy_qs:parse_qs/1 * A function was added to build query strings: cowboy_qs:qs/1 * Also added cowboy_qs:urlencode/1 and cowboy_qsurldecode/1
2013-10-23Move cookie parsing/building code to cowlibLoïc Hoguin
The code for parsing has also been rewritten to be more efficient and to be able to handle cookie values with space inside them properly. Update cowlib to 0.2.0.

2013-06-10Avoid crashing in cowboy_req on invalid Accept-Encoding headerAli Sabil
Certain clients send malformed Accept-Encoding headers, which causes cowboy_req to crash is compression is enabled.
2013-05-31Don't crash on empty Cookie headerLoïc Hoguin
It's not allowed, however a heavily deployed client (Flash player) can send such an empty header, therefore we make a special condition for it and return an empty list when it happens.
2013-05-30Add experimental and incomplete SPDY supportLoïc Hoguin
The SPDY connection processes are also supervisors. Missing: * sendfile support * request body reading support

2013-05-16Improve the specs for cowboy_req:init_stream/4Loïc Hoguin
2013-05-16Make the HTTP version type more practicalLoïc Hoguin
Now instead of {1, 1} we have 'HTTP/1.1', and instead of {1, 0} we have 'HTTP/1.0'. This is more efficient, easier to read in crash logs, and clearer in the code.
2013-05-15Remove cowboy_req:fragment/1Loïc Hoguin
Clients do not send it. We skip the value if we receive it now, as it shouldn't happen, and won't for all the mainstream clients.

2013-04-26Add chunked response body funJames Fish
Adds a new type of streaming response fun. It can be set in a similar way to a streaming body fun with known length: Req2 = cowboy_req:set_resp_body_fun(chunked, StreamFun, Req) The fun, StreamFun, should accept a fun as its single argument. This fun, ChunkFun, is used to send chunks of iodata: ok = ChunkFun(IoData) ChunkFun should not be called with an empty binary or iolist as this will cause HTTP 1.1 clients to believe the stream is over. The final (0 length) chunk will be sent automatically - even if it has already been sent - assuming no exception is raised. Also note that the connection will close after the last chunk for HTTP 1.0 clients.
