Don't send the response immediately when using h2spec In some cases we were sending a response faster than h2spec was sending us the test case data, resulting in the request being processed successfully instead of failing as expected. 2017-11-27 13:23:31 +01:00			`%% This module sends a hello world response after a delay.`

Graceful shutdown Note: This commit makes cowboy depend on cowlib master. Graceful shutdown for HTTP/2: 1. A GOAWAY frame with the last stream id set to 2^31-1 is sent and a timer is started (goaway_initial_timeout, default 1000ms), to wait for any in-flight requests sent by the client, and the status is set to 'closing_initiated'. If the client responds with GOAWAY and closes the connection, we're done. 2. A second GOAWAY frame is sent with the actual last stream id and the status is set to 'closing'. If no streams exist, the connection terminates. Otherwise a second timer (goaway_complete_timeout, default 3000ms) is started, to wait for the streams to complete. New streams are not accepted when status is 'closing'. 3. If all streams haven't completed after the second timeout, the connection is forcefully terminated. Graceful shutdown for HTTP/1.x: 1. If a request is currently being handled, it is waited for and the response is sent back to the client with the header "Connection: close". Then, the connection is closed. 2. If the current request handler is not finished within the time configured in transport option 'shutdown' (default 5000ms), the connection process is killed by its supervisor (ranch). Implemented for HTTP/1.x and HTTP/2 in the following scenarios: * When receiving exit signal 'shutdown' from the supervisor (e.g. when cowboy:stop_listener/3 is called). * When a connection process is requested to terminate using sys:terminate/2,3. LH: Edited tests a bit and added todos for useful tests to add. 2020-10-08 17:53:25 +02:00			`init(Req, Delay) when is_integer(Delay) ->`
