2020-11-02Initial implementation of Websocket over HTTP/2http2-websocketLoïc Hoguin
2020-10-21Fix cookie handling when tunnel and origin schemes mismatchLoïc Hoguin
The cookie_ignore_informational has been moved to http_opts and http2_opts. Also fix an issue when using 'protocols' in gun:open. When connecting via TLS the protocol's options were discarded.
2020-10-19Fix cookies for tunnelsLoïc Hoguin
There are still small issues left to fix. In particular the set_cookie command should be replaced with doing the same in the protocol itself so that the scheme is correct. So CookieStore must be propagated to all callbacks.
2020-10-16Remove commented codeLoïc Hoguin
2020-10-16Add or fix events inside or related to CONNECT tunnelsLoïc Hoguin
2020-10-07Propagate timeouts to the right layer in HTTP/2 tunnelsLoïc Hoguin
This temporarily depends on Cowlib master.
2020-10-07Default keepalive to infinity for all protocolsLoïc Hoguin
For HTTP/2 some servers are not fond of receiving pings, especially if there's no stream at the time. (particularly gRPC servers). This is an odd decision for sure. Rather than trying to accomodate for their logic the ping is no longer sent by default. For Websocket sending a ping is a new feature in Gun 2.0 so I'm just being conservative there.
2020-10-05Improve some 'todo' return values and argumentsLoïc Hoguin
While most of this functionality isn't implemented this is not a reason to let them return invalid values.
2020-10-03Fix Dialyzer warningsLoïc Hoguin
2020-10-03Add tunnel_SUITE testing all 3-layer combinationsLoïc Hoguin
The test suite is 216 tests with a tunnel created via two proxies leading to one origin server. The tests are for example socks5_h2_https where socks5 identifies the first SOCKS5 proxy, h2 the second HTTP/2 CONNECT proxy and https the secure HTTP/1.1 origin server. The test not only sets up the tunnel and does a request (or sends/receives data in the case of raw origin servers) but also confirms that the stream_info and info data is correct.
2020-09-21Ensure the right stream_ref is passed around HTTP/2 tunnelsLoïc Hoguin
2020-09-21Fix compilation and Dialyzer warningsLoïc Hoguin
2020-09-21Fix gun:stream_info/2 when gun_tunnel is involvedLoïc Hoguin
2020-09-21Initial success for h2 CONNECT -> https CONNECT -> httpsLoïc Hoguin
2020-09-21Add test HTTP/2 CONNECT -> HTTP/1.1 CONNECT -> originLoïc Hoguin
Implements gun:connect with a tunnel.
2020-09-21Add more HTTP/2 CONNECT testsLoïc Hoguin
2020-09-21Add a gun:stream_ref() type and fix DialyzerLoïc Hoguin
2020-09-21Refactor protocol handling via gun_protocolsLoïc Hoguin
2020-09-21Few more tests and fixesLoïc Hoguin
2020-09-21Replace gun_tunnel_up/3 message with /4 variantLoïc Hoguin
Also fixes all the tests. Lots of work remain around protocols (how best to pass the base stream_ref to them? maybe the current solution, maybe a new argument to Protocol:init) and strengthen the concept of stream_ref, at least with its own type.
2020-09-21Rename the 3-arity gun_socks_up to gun_tunnel_upLoïc Hoguin
2020-09-21Add gun_tunnel_up message to HTTP/2 CONNECTLoïc Hoguin
2020-09-21First working HTTPS over secure HTTP/2Loïc Hoguin
Has a timer:sleep/1 though because there is currently no way to wait for the TLS handshake to complete.
2020-09-21Make gun_socks_up stream-specific for HTTP/2 CONNECTLoïc Hoguin
2020-09-21Make HTTP/2 CONNECT to a SOCKS server workLoïc Hoguin
2020-09-21Add HTTP/2 CONNECT tests with Cowboy as originLoïc Hoguin
2020-09-21Add the base_stream_ref to gun_http/gun_http2Loïc Hoguin
2020-09-21HTTP/2 over HTTP/2 CONNECTLoïc Hoguin
2020-09-21Improve HTTP/2 CONNECT to non-HTTP originLoïc Hoguin
Now has a proper StreamRef given to it by the CONNECT stream.
2020-09-21Make gun:stream_info/2 return intermediaries for HTTP/2 CONNECTLoïc Hoguin
2020-09-21Initial HTTP/2 CONNECT implementationLoïc Hoguin
2020-04-16Empty the commands queue when returningLoïc Hoguin
2020-03-12Make Gun use the cookie store when configured toLoïc Hoguin
2020-02-27Remove two unnecessary clausesLoïc Hoguin
As reported by Dialyzer.
2020-02-27Use specific error when HTTP/2 receives HTTP/1 responseLoïc Hoguin
2020-02-27Detect invalid HTTP/2 preface errorsLoïc Hoguin
And make sure all HTTP/2 connection_error(s) result in a gun_down message containing the error. In the preface case we do not send a gun_error message (because there's no stream open yet) and gun_down was always saying normal. Also make sure the human readable reason is included in the gun_error message, if any.
2020-02-10Handle cow_http2_machine timeoutsLoïc Hoguin
2019-11-04Fix a crash introduced in the previous commitLoïc Hoguin
2019-10-17Use maps for looking up HTTP/2 streamsLoïc Hoguin
This should be much faster than using lists:keyfind and friends. This matters for connections that have a lot of concurrent streams.
2019-10-01Cowlib no longer returns lingering_data tuplesLoïc Hoguin
2019-09-26Don't send duplicate gun_error messages to the same processLoïc Hoguin
2019-09-26Remove UnprocessedStreams from the gun_down messageLoïc Hoguin
2019-09-26Add reply_to option to ws_upgrade; remove notowner entirelyLoïc Hoguin
The reply_to option is also propagated when we switch protocols.
2019-09-24Add auto-ping to Websocket and a silence_pings optionLoïc Hoguin
The auto-ping will at regular interval send a ping frame. The silence_pings option defaults to true. It can be set to false when the user needs to receive ping/pong frames.
2019-09-23Accept all cow_http2_machine optionsLoïc Hoguin
2019-09-22Rework state transitions resulting from from protocol changesLoïc Hoguin
2019-09-22Improve retrieval of keepalive optionLoïc Hoguin
2019-09-22Supports going through multiple Socks proxiesLoïc Hoguin
This commit also reworks the switch_protocol command. The `P | {P, Opts}` type is used here as well. This allows us to remove the code specific to Websocket. In addition a few new protocol functions allow us to declare what's the name of the options key for the protocol and what the capabilities are with regard to keepalive.
2019-09-22Move and merge all TLS handshakes to the main Gun codeLoïc Hoguin
There's now an initial_tls_handshake state for the initial connection with handshake, and tls_handshake state for any subsequent TLS handshakes. The Socks5 code will be able to reuse this tls_handshake state to perform its own transport switches.
2019-09-13Use cow_http2_machine:ensure_windowLoïc Hoguin
Gun was very inefficient at receiving HTTP/2 bodies. Switching to ensure_window and increasing the default window sizes brings the response body reading performance at least on par with the one for HTTP/1.1. This has a small negative impact on message flow control because we stop updating the window later than we did before, increasing the number of extra messages we may send. The exact amount depends on configuration and the exact moment flow control kicks in.
