Andy Green	f9f6bb66fe	lws_validity: unified connection validity tracking ... Refactor everything around ping / pong handling in ws and h2, so there is instead a protocol-independent validity lws_sul tracking how long it has been since the last exchange that confirms the operation of the network connection in both directions. Clean out periodic role callback and replace the last two role users with discrete lws_sul for each pt.	2019-09-22 09:35:07 -07:00
Andy Green	ba754c4cb2	h2: unify immortal stream tracking across SSE and ws substreams ... It was already correct but add helpers to isolate and deduplicate processing adding and closing a generically immortal stream. Change the default 31s h2 network connection timeout to be settable by .keepalive_timeout if nonzero. Add a public api allowing a client h2 stream to transition to half-closed LOCAL (by sending a 0-byte DATA with END_STREAM) and mark itself as immortal to create a read-only long-poll stream if the server allows it. Add a vhost server option flag LWS_SERVER_OPTION_VH_H2_HALF_CLOSED_LONG_POLL which allows the vhost to treat half-closed remotes as immortal long poll streams.	2019-09-22 03:08:36 -07:00
