2017-02-19Change the type of bindings from a list to a mapLoïc Hoguin
Maps make more sense because the keys are unique.
2017-02-19Change the order of set_resp_cookie argumentsLoïc Hoguin
The Opts value is put last, to be more consistent with the rest of the cowboy_req module. Additionally a test handler was fixed which reduced the number of errors in http_SUITE.
2017-02-18Allow passing options to sub protocolsLoïc Hoguin
Before this commit we had an issue where configuring a Websocket connection was simply not possible without doing magic, adding callbacks or extra return values. The init/2 function only allowed setting hibernate and timeout options. After this commit, when switching to a different type of handler you can either return {module, Req, State} or {module, Req, State, Opts} where Opts is any value (as far as the sub protocol interface is concerned) and is ultimately checked by the custom handlers. A large protocol like Websocket would accept only a map there, with many different options, while a small interface like loop handlers would allow passing hibernate and nothing else. For Websocket, hibernate must be set from the websocket_init/1 callback, because init/2 executes in a separate process. Sub protocols now have two callbacks: one with the Opts value, one without. The loop handler code was largely reworked and simplified. It does not need to manage a timeout or read from the socket anymore, it's the job of the protocol code. A lot of unnecessary stuff was therefore removed. Websocket compression must now be enabled from the handler options instead of per listener. This means that a project can have two separate Websocket handlers with different options. Compression is still disabled by default, and the idle_timeout value was changed from inifnity to 60000 (60 seconds), as that's safer and is also a good value for mobile devices.

2014-11-24Docs clarification when returning a list of ws framesLoïc 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.
2014-10-08change init/2 to return #state{} in documentationStefan Strigler
Most examples returned 'Opts' as given by second argument to init. By using '#state{}' the examples make it more clear that this is what is being passed as 'State' to all subsequent callbacks (if any).
2014-10-04Fix a bad link in the guideLoïc Hoguin
2014-10-04Reverse the order of arguments of match_* functionsLoïc Hoguin
Wasn't following the same order as the rest of the module.
2014-10-03Remove the REST known_content_type callbackLoïc Hoguin
This callback was simply useless.
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.
2014-09-24Remove the error tuple return value for middlewaresLoïc Hoguin
It wasn't interesting compared to simply returning a halt tuple with an explicit reply.
2014-09-24Remove the onrequest hookLoïc Hoguin
It was redundant with middlewares. Allows us to save a few operations for every incoming requests.
2014-09-23Make routing constraints use the fields formatLoïc Hoguin
This makes routing more in line with the rest of Cowboy and allows us to use cowboy_constraints directly.
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.
2014-08-11Fix REST guide reference to accept_missing_postAli Sabil
The guide refers to accept_missing_post instead of allow_missing_post.
