From 8cb9d242b0a665cada6de8b9a9dfa329e0c06ee9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Lo=C3=AFc=20Hoguin?= Date: Tue, 31 Jan 2023 11:07:31 +0100 Subject: Initial HTTP/3 implementation This includes Websocket over HTTP/3. Since quicer, which provides the QUIC implementation, is a NIF, Cowboy cannot depend directly on it. In order to enable QUIC and HTTP/3, users have to set the COWBOY_QUICER environment variable: export COWBOY_QUICER=1 In order to run the test suites, the same must be done for Gun: export GUN_QUICER=1 HTTP/3 support is currently not available on Windows due to compilation issues of quicer which have yet to be looked at or resolved. HTTP/3 support is also unavailable on the upcoming OTP-27 due to compilation errors in quicer dependencies. Once resolved HTTP/3 should work on OTP-27. Because of how QUIC currently works, it's possible that streams that get reset after sending a response do not receive that response. The test suite was modified to accomodate for that. A future extension to QUIC will allow us to gracefully reset streams. This also updates Erlang.mk. --- src/cowboy_http.erl | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/cowboy_http.erl') diff --git a/src/cowboy_http.erl b/src/cowboy_http.erl index ee1e725..9c92ec5 100644 --- a/src/cowboy_http.erl +++ b/src/cowboy_http.erl @@ -12,6 +12,8 @@ %% ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF %% OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. +%% @todo Worth renaming to cowboy_http1. +%% @todo Change use of cow_http to cow_http1 where appropriate. -module(cowboy_http). -export([init/6]). @@ -1531,7 +1533,7 @@ maybe_socket_error(_, Result = {ok, _}, _) -> maybe_socket_error(State, {error, Reason}, Human) -> terminate(State, {socket_error, Reason, Human}). --spec terminate(_, _) -> no_return(). +-spec terminate(#state{} | undefined, _) -> no_return(). terminate(undefined, Reason) -> exit({shutdown, Reason}); terminate(State=#state{streams=Streams, children=Children}, Reason) -> -- cgit v1.2.3
