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.

2013-05-15Add two missing terminate reasons to http/loop handlers specsLoïc Hoguin
2013-01-26Update handler callback specsAndrew Majorov
There is one another {upgrade, ...} quintuple allowed as the result of Handler:init call, somewhy not mentioned in the callback specifications.
2013-01-22Replace terminate/2 with terminate/3, adding a ReasonLoïc Hoguin
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.

2012-08-27Update behaviours for R15B+Loïc Hoguin
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.
2012-05-23Update version to 0.6.00.6.0Loïc Hoguin
Also update the CHANGELOG and copyright years.
2011-07-06Add documentation for the public interface.Loïc Hoguin
This is probably not perfect yet but it should be better than nothing. We'll improve things with feedback received from the many users.
2011-06-27Add the remaining missing specsLoïc Hoguin
Found thanks to warn_missing_spec and added with the help of typer. Eunit functions do not have specs yet however.
2011-03-24Add the cowboy_http_handler behaviour.Loïc Hoguin
