> Why is this needed? What does this improve excactly? @ok2c RFC 9113 recommends two-phase graceful shutdown for HTTP/2: initial GOAWAY with 2^31-1, wait one RTT, then final GOAWAY with the actual last processed stream id. This improves correctness of connection draining by avoiding shutdown races around in-flight stream creation and by preserving an accurate final GOAWAY boundary. https://www.rfc-editor.org/rfc/rfc9113.html#section-6.8 “A server that is attempting to gracefully shut down a connection SHOULD send an initial GOAWAY frame with the last stream identifier set to 2^31-1 and a NO_ERROR code.” “After allowing time for any in-flight stream creation (at least one round-trip time), the server MAY send another GOAWAY frame with an updated last stream identifier.” -- This is an automated message from the Apache Git Service.
