From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Victor Toso Date: Fri, 11 Nov 2016 14:19:53 +0100 Subject: [PATCH] file-xfer: do not send unnecessary 0 bytes messages This fixes the situation when VDAgent receives 0 byte message regarding a file-transfer operation that was terminated in the previous message. This makes the VDAgent to send a STATUS_ERROR after STATUS_SUCCESS to client.
