2014-05-08spice: fix libvirt snapshotsGerd Hoffmann
Only notify spice-server about migration events in case we got target host information beforehand. So we kick the seamless spice client migration only in case a actual live migration happens, not when libvirt uses live-migration-to-file for snapshotting.

2014-05-08spice: fix "info spice"Gerd Hoffmann
In case no listening address was specified, "info spice" reports "0.0.0.0" as address. Which is incorrect in case spice is listening on ipv6. Replace it by a wildcard "*" to indicate it is not limited to a specific address. Note: Being more specific is not possible without extending the spice-server api. The socket is handled by spice-server not qemu, so qemu can't easily figure the actual socket address. Reported-by: David Jaša <djasa@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-04-08gtk: Implement grab-on-click behavior in relative modeTakashi Iwai
This patch changes the behavior in the relative mode to be compatible with other UIs, namely, grabbing the input at the first left click. It improves the usability a lot; otherwise you have to press ctl-alt-G or select from menu at each time you want to move the pointer. Also, the input grab is cleared when the current mode is switched to the absolute mode. The automatic reset of the implicit grabbing is needed since the switching to the absolute mode happens always after the click even on Gtk. That is, we cannot check whether the absolute mode is already available at the first click time even though it should have been switched in X11 input driver side.

2014-04-07gtk: Remember the last grabbed pointer positionTakashi Iwai
It's pretty annoying that the pointer reappears at a random place once after grabbing and ungrabbing the input. Better to restore to the original position where the pointer was grabbed.

2014-04-07gtk: Fix the relative pointer tracking modeTakashi Iwai
The relative pointer tracking mode was still buggy even after the previous fix of the motion-notify-event since the events are filtered out when the pointer moves outside the drawing window due to the boundary check for the absolute mode. This patch fixes the issue by moving the unnecessary boundary check into the if block of absolute mode, and keep the coordinate in the relative mode even if it's outside the drawing area. But this makes the coordinate (last_x, last_y) possibly pointing to (-1,-1), introduce a new flag to indicate the last coordinate has been updated.

2014-04-07gtk: Use gtk generic event signal instead of motion-notify-eventTakashi Iwai
The GDK motion-notify-event isn't generated when the pointer goes out of the target window even if the pointer is grabbed, which essentially means to lose the pointer tracking in gtk-ui. Meanwhile the generic "event" signal is sent when the pointer is grabbed, so we can use this and pick the motion notify events manually there instead.

2014-03-19qom: Add check() argument to object_property_add_link()Stefan Hajnoczi
There are currently three types of object_property_add_link() callers: 1. The link property may be set at any time. 2. The link property of a DeviceState instance may only be set before realize. 3. The link property may never be set, it is read-only. Something similar can already be achieved with object_property_add_str()'s set() argument. Follow its example and add a check() argument to object_property_add_link(). Also provide default check() functions for case #1 and #2. Case #3 is covered by passing a NULL function pointer.

2014-03-19qom: Make QOM link property unref optionalStefan Hajnoczi
Some object_property_add_link() callers expect property deletion to unref the link property object. Other callers expect to manage the refcount themselves. The former are currently broken and therefore leak the link property object. This patch adds a flags argument to object_property_add_link() so the caller can specify which refcount behavior they require. The new OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be unreferenced when the property is deleted. This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c, s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c. Rationale for refcount behavior: * hw/core/qdev.c - bus children are explicitly unreferenced, don't interfere - parent_bus is essentially a read-only property that doesn't hold a refcount, don't unref - hotplug_handler is leaked, do unref * hw/dma/xilinx_axidma.c - rx stream "dma" links are set using set_link, therefore they need unref - tx streams are set using set_link, therefore they need unref * hw/net/xilinx_axienet.c - same reasoning as hw/dma/xilinx_axidma.c * hw/pcmcia/pxa2xx.c - pxa2xx bypasses set_link and therefore does not use refcounts * hw/s390x/s390-virtio-bus.c * hw/virtio/virtio-pci.c * hw/virtio/virtio-rng.c * ui/console.c - set_link is used and there is no explicit unref, do unref Cc: Peter Crosthwaite <peter.crosthwaite@petalogix.com> Cc: Alexander Graf <agraf@suse.de> Cc: Anthony Liguori <aliguori@amazon.com> Cc: "Michael S.

vnc_update_client currently scans the dirty bitmap of each client bitwise which is a very costly operation if only few bits are dirty. vnc_refresh_server_surface does almost the same. this patch optimizes both by utilizing the heavily optimized function find_next_bit to find the offset of the next dirty bit in the dirty bitmaps.
