annotate src/http/v3/ngx_http_v3_streams.c @ 8724:fc64ab301bad quic
QUIC: connection shutdown.
The function ngx_quic_shutdown_connection() waits until all non-cancelable
streams are closed, and then closes the connection. In HTTP/3 cancelable
streams are all unidirectional streams except push streams.
The function is called from HTTP/3 when client reaches keepalive_requests.
