2020-01-06Use active,NLoïc Hoguin
This reduces the number of times we need to ask for more packets, and as a result we get a fairly large boost in performance, especially with HTTP/1.1. Unfortunately this makes Cowboy require at least Erlang/OTP 21.3+ because the ssl application did not have active,N. For simplicity the version required will be Erlang/OTP 22+. In addition this change improves hibernate handling in cowboy_websocket. Hibernate will now work for HTTP/2 transport as well, and stray or unrelated messages will no longer cancel hibernate (the process will handle the message and go back into hibernation). Thanks go to Stressgrid for benchmarking an early version of this commit: https://stressgrid.com/blog/cowboy_performance_part_2/
2019-10-09Implement flow control for HTTP/1.1Loïc Hoguin
We now stop reading from the socket unless asked to, when we reach the request body. The option initial_stream_flow_size controls how much data we read without being asked, as an optimization. We may also have received additional data along with the request headers. This commit also reworks the timeout handling for HTTP/1.1 because the stray timeout message was easily reproducible after implementing the flow control. The issue should be gone for good this time.

2017-12-07Add more rfc7231 tests and a new max_skip_body_length optionLoïc Hoguin
The option controls how much body we accept to skip for HTTP/1.1 connections when the user code did not consume the body fully. It defaults to 1MB.
2017-06-07Remove NumAcceptors argument from start_clear/tlsLoïc Hoguin
They are now cowboy:start_clear/3 and cowboy:start_tls/3. The NumAcceptors argument can be specified via the num_acceptor transport option. Ranch has been updated to 1.4.0 to that effect.
