annotate src/event/quic/ngx_event_quic_streams.c @ 9003:6c1dfd072859 quic

QUIC: switch stream to DATA_RECVD state. The switch happens when received byte counter reaches stream final size. Previously, this state was skipped. The stream went from SIZE_KNOWN to DATA_READ when all bytes were read by application. The change prevents STOP_SENDING frames from being sent when all data is received from client, but not yet fully read by application.
