2016-08-10Add a lot of todosLoïc Hoguin
2016-08-10Add tests for responses and request body readingLoïc Hoguin
This is a large commit. The cowboy_req interface has largely changed, and will change a little more. It's possible that some examples or tests have not been converted to the new interface yet. The documentation has not yet been updated. All of this will be fixed in smaller subsequent commits. Gotta start somewhere...

2016-06-21Add cowboy_req:uri/1,2Loïc Hoguin
Along with more cowboy_req tests. This commit also removes cowboy_req:url/1 and cowboy_req:host_url/1 in favor of the much more powerful new set of functions.

2016-06-13Merge static_world and web_server examplesLoïc Hoguin
The new example is called file_server and it's basically the same as web_server was. The name is clearer than the original, all examples being "Web servers". The new example is also tested and the test suite has been refactored a little.

2016-03-14Clarify comments about remaining tests to add to rfc7540_SUITELoïc Hoguin
2016-03-13Fix most remaining HTTP/2 handshake testsLoïc Hoguin
One category of tests involving the SETTINGS ack still fails. It is probably wise to leave these until more SETTINGS related tests are written.
2016-03-13Fix more HTTP/2 handshake test casesLoïc Hoguin
2016-03-12Add initial HTTP/1.1 Upgrade to HTTP/2Loïc Hoguin
The same edge cases that fail with other handshake methods also fail here (mostly bad preface/timeouts stuff). In addition, the HTTP2-Settings header contents are currently not checked and so the related edge case tests also fail.
2016-03-10Add the beginning of the rfc7540 test suiteLoïc Hoguin
Currently only testing handshake. Tests that pass currently involve no request/response. ALPN and prior knowledge support have some edge cases left to fix. HTTP/1.1 Upgrade has not been implemented yet.
2016-03-06Completely remove SPDYLoïc Hoguin
2016-03-05Initial commit with connection/streamsLoïc Hoguin
Breaking changes with previous commit. This is a very large change, and I am giving up on making a single commit that fixes everything. More commits will follow slowly adding back features, introducing new tests and fixing the documentation. This change contains most of the work toward unifying the interface for handling both HTTP/1.1 and HTTP/2. HTTP/1.1 connections are now no longer 1 process per connection; instead by default 1 process per request is also created. This has a number of pros and cons. Because it has cons, we also allow users to use a lower-level API that acts on "streams" (requests/responses) directly at the connection process-level. If performance is a concern, one can always write a stream handler. The performance in this case will be even greater than with Cowboy 1, although all the special handlers are unavailable. When switching to Websocket, after the handler returns from init/2, Cowboy stops the stream and the Websocket protocol takes over the connection process. Websocket then calls websocket_init/2 for any additional initialization such as timers, because the process is different in init/2 and websocket_*/* functions. This however would allow us to use websocket_init/2 for sending messages on connect, instead of sending ourselves a message and be subject to races. Note that websocket_init/2 is optional. This is all a big change and while most of the tests pass, some functionality currently doesn't. SPDY is broken and will be removed soon in favor of HTTP/2. Automatic compression is currently disabled. The cowboy_req interface probably still have a few functions that need to be updated. The docs and examples do not refer the current functionality anymore. Everything will be fixed over time. Feedback is more than welcome. Open a ticket!
2015-08-07Use 'Connection' header only when necessaryAlexey Lebedeff
Fixes #839 when 'Connection: Keep-Alive' wasn't sent in a HTTP/1.0 response. Now the usage of 'Connection' header is consistent with current protocol version: when this header is not specified explicitly in the response, HTTP/1.0 implies 'Connection: close' and HTTP/1.1 implies 'Connection: Keep-Alive'. So if current 'Connection' value matches the default value of current protocol, we won't state obvious fact in the response; and vice versa. Amended to fix and improve tests, and revert the variable name change from HTTP11Headers to StdHeaders. I think it's still good to leave it as is because it's not really a standard header for HTTP/1.0, and it's gone from HTTP/2 entirely.
2015-07-22Fix autobahn test suite report link when used in CILoïc Hoguin
2015-07-22Add autobahn test suite output to the consoleLoïc Hoguin
2015-05-05Add rfc7230 test suite and update others to recent GunLoïc Hoguin
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.
2015-03-06Update Cowlib to 1.2.0; adds Websocket permessage-deflateLoïc Hoguin
The Websocket text frames should also be less resource intensive to validate now, with a binary concatenation avoided.
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
2014-11-07Rename 'halt' to 'stop' for better consistencyLoïc Hoguin
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.
2014-11-07Rename 'shutdown' close reason and tuples to 'stop'Loïc Hoguin
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.
2014-10-04Reverse the order of arguments of match_* functionsLoïc Hoguin
Wasn't following the same order as the rest of the module.
2014-10-03Fix two edge cases when the request-line provided is invalidLoïc Hoguin
2014-09-30Improve handler interface and documentationLoïc Hoguin
This change simplifies a little more the sub protocols mechanism. Aliases have been removed. The renaming of loop handlers as long polling handlers has been reverted. Plain HTTP handlers now simply do their work in the init/2 callback. There is no specific code for them. Loop handlers now follow the same return value as Websocket, they use ok to continue and shutdown to stop. Terminate reasons for all handler types have been documented. The terminate callback is now appropriately called in all cases (or should be). Behaviors for all handler types have been moved in the module that implement them. This means that cowboy_handler replaces the cowboy_http_handler behavior, and similarly cowboy_loop replaces cowboy_loop_handler, cowboy_websocket replaces cowboy_websocket_handler. Finally cowboy_rest now has the start of a behavior in it and will have the full list of optional callbacks defined once Erlang 18.0 gets released. The guide has been reorganized and should be easier to follow.
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.
2014-09-24Small tweak from erlang:error/1 to error/1Loïc Hoguin
2014-09-24Remove the onrequest hookLoïc Hoguin
It was redundant with middlewares. Allows us to save a few operations for every incoming requests.
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)
