annotate src/http/v3/ngx_http_v3_request.c @ 8460:72f9ff4e0a88 quic
HTTP/3: close QUIC connection with HTTP/QPACK errors when needed.
Previously errors led only to closing streams.
To simplify closing QUIC connection from a QUIC stream context, new macro
ngx_http_v3_finalize_connection() is introduced. It calls
ngx_quic_finalize_connection() for the parent connection.
