Initial work on a ct test suite for the HTTP protocol. Handles two basic tests for both HTTP and HTTPS. Also renames 'make test' into 'make tests'. 2011-04-08 16:30:37 +02:00			`%% Feel free to use, reuse and abuse the code in this file.`

Unify the init and terminate callbacks 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. 2014-09-26 15:58:44 +03:00			`-export([init/2]).`

Fix a bug where dupe headers were sent in cowboy_http_req:reply/4. 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. 2011-04-14 01:26:02 +02:00

Breaking update of the cowboy_req interface 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. 2014-09-23 16:43:29 +03:00			`{ok, cowboy_req:reply(200, Headers, Body, Req), State}.`
