Add {shutdown, Req} to websocket_init/3 to fail a websocket upgrade This change allows application developers to refuse websocket upgrades by returning {shutdown, Req}. The application can also send a reply with a custom error before returning from websocket_init/3, otherwise an error 400 is sent. Note that right now Cowboy closes the connection immediately. Also note that neither terminate/3 nor websocket_terminate/3 will be called when the connection is shutdown by websocket_init/3. 2011-10-10 09:09:15 +02:00			`%% Feel free to use, reuse and abuse the code in this file.`

Reorganize the websocket test suite We now have the suite specific modules in the data folder. Compilation is performed by the Makefile instead of ct_run. 2013-04-22 15:55:22 +02:00			`-module(ws_init_shutdown).`
Update behaviours for R15B+ This effectively drops the R14B compatibility. The cowboy_req:req() type will be introduced in a future commit. It refers to the #http_req{} record. 2012-08-27 12:46:42 +02:00			`-behaviour(cowboy_websocket_handler).`
Replace terminate/2 with terminate/3, adding a Reason This should have been done a long time ago, back when I initially added Websocket support. This is the first part of two in improving loop handler support with regards to socket closure. Reason may include: {normal, shutdown} for the most normal shutdown, {normal, timeout} for a loop handler timeout shutdown, or {error, _} if an error occured. 2013-01-22 02:34:18 +01:00			`-export([init/3]).`

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			`{shutdown, cowboy_req:reply(403, Req)}.`
