2019-09-05Implement graceful shutdownLoïc Hoguin
The graceful shutdown is implemented through a new 'closing' state. This state is entered under different circumstances depending on the protocol. The gun:shutdown/1 function is now implemented and documented. It allows shutting down the connection gracefully regardless of the current state of the connection and for all protocols. The behavior is entirely dependent on the protocol. For HTTP/1.1 the connection stays up only until after the current stream is complete; other streams are immediately canceled. For HTTP/2 a GOAWAY frame is sent and existing streams continue to be processed. The connection is closed after all streams are processed and the server's GOAWAY frame is received. For Websocket a close frame is sent. The connection is closed when receiving the server's close frame. In all cases the closing_timeout option defines how long we wait, as a maximum, before closing the connection after the graceful shutdown was started. The graceful shutdown is also initiated when the owner process goes away; when sending an HTTP/1.1 request with the connection: close header; when receiving an HTTP/1.1 response with the connection: close header; when receiving an HTTP/1.0 response without a connection header; when the server sends a GOAWAY HTTP/2 frame; or when we send or receive a Websocket close frame. Along with these changes, the gun:ws_send/2 function now accepts a list of frames as argument. Those frames may include a close frame that initiates the graceful shutdown.

2019-04-26Add upgrade/ws tuples to gun:await/2,3,4Loïc Hoguin

2018-12-31Fix stripping stream reference in gun_httpPiotr Bober
An invalid stream reference (the websocket tuple wrapper) was sent in the gun_data message. Also moves autobahn to its own test suite.

2018-06-03Change messages to gun_upgrade and gun_ws with stream referenceLoïc Hoguin

2015-08-16Fix a harmless typo in a testLoïc Hoguin
2015-04-10Add headers to gun_ws_upgrade messageLoïc Hoguin
Also improves the code and documentation about this message. It was incorrectly specified that a gun_ws_upgrade message could be sent on error; instead a gun_response is sent.
2015-04-09Add gun_up and gun_down messagesLoïc Hoguin
The flush(Pid) function was enhanced to also discard Websocket messages and the new up/down messages.
2015-04-08Use maps for and improve optionsLoïc Hoguin
The type option has been removed. The transport and protocols options can be used in its place. The transport_opts option can be used to specify transport options. The http_opts and spdy_opts options can be used to specify protocol specific options. The keepalive option is now a protocol specific option. Defaults depending on the port number have changed. Now only port 443 uses ssl by default, other ports use tcp.
2015-03-12Add initial Websocket supportLoïc Hoguin
All autobahntestsuite tests pass including the permessage-deflate compression tests. Some of the tests pass in a non-strict fashion. They are testing for protocol errors and expect events to happen in a particular order, which is not respected by Gun. Gun fails earlier than is expected due to concurrent processing of frames. The implementation when error occurs during handshake is probably a bit rough at this point. The documentation is also incomplete and/or wrong at this time, though this is the general state of the Gun documentation and will be resolved in a separate commit.
