GTK without VTE is needed for hosts which don't support VTE (for example
all variants of MinGW), but it can also be reasonable for other hosts.

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.

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

this fixes invalid rectangle updates observed after commit 12b316d
with the vmware VGA driver. The issues occured because the server
and client surface update seems to be out of sync at some points
and the max width of the surface is not dividable by
VNC_DIRTY_BITS_PER_PIXEL (16).

We were using the wrong coordinates, this fixes things to match the
original gtk2 implementation.
You can see this error in action by using -vga qxl, however even after this
patch the mouse warps in small increments up and to the left, -7x and -3y
pixels at a time, until the pointer is warped off the widget. I think it's
a qxl bug, but the next patch covers it up.

The following artifical test (just the bitmap operation part) running
vnc_update_client 65536 times on a 2560x2048 surface illustrates the
performance difference:
All bits clean - vnc_update_client_new: 0.07 secs
vnc_update_client_new2: 0.07 secs
vnc_update_client_old: 10.98 secs
All bits dirty - vnc_update_client_new: 11.26 secs
- vnc_update_client_new2: 0.29 secs
vnc_update_client_old: 20.19 secs
Few bits dirty - vnc_update_client_new: 0.07 secs
- vnc_update_client_new2: 0.07 secs
vnc_update_client_old: 10.98 secs
vnc_update_client_new2 shows the performance of vnc_update_client
with this patch added.
Comparing with the test run of the last patch the performance
is at least unchanged while it is significantly improved
for the all bits dirty case.

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.
The following artifical test (just the bitmap operation part) running
vnc_update_client 65536 times on a 2560x2048 surface illustrates the

vnc_update_client_old: 20.19 secs
Few bits dirty - vnc_update_client_new: 0.08 secs
vnc_update_client_old: 10.98 secs
The case for all bits dirty is still rather slow, this
is due to the implementation of find_and_clear_dirty_height.
This will be addresses in a separate patch.

Remove vnc_update_client_sync wrapper, replace it with an additional

vnc_update_client (i.e. skip it in case of a client disconnect).

Hi,
When I use RealVNC viewer client (http://www.realvnc.com/) to connect vnc server,
the client disconnect suddenly, and I click reconnect button immediately, then the Qemu crashed.
In the function vnc_worker_thread_loop, will call vnc_async_encoding_start
to set the local vs->output buffer by global queue's buffer. Then send rectangles to
the vnc client call function vnc_send_framebuffer_update. Finally, Under normal circumstances,
call vnc_async_encoding_end to set the global queue'buffer by the local vs->output conversely.
When the vnc client disconnect, the job->vs->csock will be set to -1. And the current prcoess
logic will goto disconnected partion without call function vnc_async_encoding_end.
But, the function vnc_send_framebuffer_update will call buffer_reserve, which
maybe call g_realloc reset the local vs's buffer, meaning the global queue's buffer is modified also.
If anyone use the original global queue's buffer memory will cause corruption and then crash qemu.
This patch assure the function vnc_async_encoding_end being called
even though the vnc client disconnect suddenly.

VncTight member uint8_t quality is either (uint8_t)-1 for lossless or
less than 10 for lossy.
tight_detect_smooth_image() first promotes it to int, then compares
with -1. Always unequal, so we always execute the lossy code. Reads
beyond tight_conf[] and returns crap when quality is actually
lossless.
Compare to (uint8_t)-1 instead, like we do elsewhere.

I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface.
The biggest changes were in the input handling, where SDL2 has done a major
overhaul, and I've had to include a generated translation file to get from
SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard
layout code works in qemu, so there may be further work if someone can point
me a test case that works with SDL1.2 and doesn't with SDL2.
Some SDL env vars we used to set are no longer used by SDL2,
Windows, OSX support is untested,
I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt
using --with-sdlabi=2.0 to select the new code should be fine, like how
gtk does it.
v1.1: fix keys in text console
v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor
v2.0: merge the SDL multihead patch into this, g_new the number of consoles
needed, wrap DCL inside per-console structure.

legacy mouse event handlers are registered in the new core,
so they receive events submitted to the new input core.
legacy kbd_mouse_event() continues to use the old code paths.
So new-core event handlers wouldn't see events submitted via
kbd_mouse_event.
This leads to the constrain that we we must transition all
kbd_mouse_event() users first to keep things working. But
that is easier to handle than translating legacy mouse events
into new-core mouse events ;)
