With gRPC it is possible that a request sending is blocked due to flow control. Moreover, further sending might be only allowed once the backend sees all the data we've already sent. With such a backend it is required to clear the TCP_NOPUSH socket option to make sure all the data we've sent are actually delivered to the backend. As such, we now clear TCP_NOPUSH in ngx_http_upstream_send_request() also on NGX_AGAIN if c->write->ready is set. This fixes a test (which waits for all the 64k bytes as per initial window before allowing more bytes) with sendfile enabled when the body was written to a file in a different context. |
