The client has been superseded by virt-viewer (
http://virt-manager.org/download/sources/virt-viewer/ ) and is no longer
being maintained.
|

Setting CHECKDIFF=1 environment variable will compare the rendering of
the selected canvas with a software canvas. This is useful for debugging
some rendering issues, however it is far from being perfect, since it's
not able to tell whether one or the other is actually faulty. It's a
strong indication though of which operations are incorrect.
Ideally, all operations should be checked, however, a few of them are
disabled by default because they fail all the time, and it looks like
pixman is not very accurate for blending/compositing (at least visually,
it seems gl has better rendering)

All the real work is being done in spice-common, so this patch is just
hooking up the virtual calls and adding the SPICE_DISPLAY_CAP_COMPOSITE
capability.
|
|
spice-common changes: STREAM_DATA_SIZED message was added in order to support
video streams with frames that their size is different from the initial size
that the stream was created with.
This patch also includes server and client adjustments to the new
SpiceMsgDisplayStreamData.

This patch will replace the common/ directory with the spice-common
project. It is for now a simple project subdirectory shared with
spice-gtk, but the goal is to make it a proper library later on.
With this change, the spice-server build is broken. The following
commits fix the build, and have been seperated to ease the review.
v2
- moves all the generated marshallers to spice-common library
- don't attempt to fix windows VS build, which should somehow be
splitted with spice-common (or built from tarball only to avoid
generation tools/libs deps)
v3
- uses libspice-common-client
- fix a mutex.h inclusion reported by Alon

Fix not destroying surfaces and other data (e.g., streams) upon disconnection.

use std::map instead of a specific template (CHash).
There is no need for special template. Moreover, using
std::map will allow easy iteration over the surfaces.

In a Xinerama setup, when X starts up and creates one of the
secondary screens, first a non-primary surface is created on the
secondary screen, and then the primary surface for this screen is
created.
This causes a crash when the guest uses Xinerama and the client
is attached to the VM before X starts (ie while the guest is
booting).
This happens because DisplayChannel::create_canvas (which is called
when creating a non-primary surface) assumes a screen has already been
set for the DisplayChannel while this only happens upon primary surface
creation. However, it uses the screen for non important stuff, so we
can test if screen() is non NULL before using it. This is what is done
in other parts of this file.
Fixes rhbz #732423

Video streams from Linux guests are oriented top-down, where gdi_canvas_put_image always
received display context for down-top oriented bitmap. I fixed create_bitmap
to consider the stream orientation.

This is more explicit about what it does, and not much longer

|
When using config.h, it must be the very first include in all source
files since it contains #define that may change the compilation process
(eg libc structure layout changes when it's used to enable large file
support on 32 bit x86 archs). This commit adds it at the beginning
of all .c and .cpp files
|
|
When OpenGL is enabled, build fails in DisplayChannel::create_surface
because Canvas *canvas is declared twice. Remove the first
declaration to fix compilation.

Currently when going / starting fullscreen if the guest resolution for one of
the monitors is higher then that monitor on the client can handle, we show a
white screen. Leaving the user stuck (unless they know the fullscreen key
switch combi) with a white screen when starting the client fullscreen from
the XPI.
This patch changes the client to fall back to windowed mode in this case
instead.
|
|
There was an error in how this was encoded in 0.4, which we need
to handle. There is still some issues with the old streams as
the luminocity handling in 0.4 was not correct.

window if the primary surface is not recreated (the monitor has been detached).

This is not supported currently anyway and was not generated before.

* Correctly check for existing canvas 0
* Don't try to unlock the screen size if there is no active screen

This is required to support multiple versions

When a message has been read from the network we now pass it into
the generated demarshaller for the channel. The demarshaller converts
the network data to in-memory structures that is passed on to the
spice internals.
Additionally it also:
* Converts endianness
* Validates sizes of message and any pointers in it
* Localizes offsets (converts them to pointers)
* Checks for zero offsets in messages where they are not supported
Some of this was previously done using custom code in the client, this
is now removed.

The command line option is renamed from "cairo" to "sw", and
similarly all filenames and types from Cairo to Sw (and similar).
|
|
Surface creation now specifies the exact format, not only the bit depth
of each surface which is used for rendering.
Additionally we now actually store the surfaces in that format, instead
of converting everything to 32bpp when drawing or e.g. handling palettes.
|
|
We now support 16bit format pixmaps as well as the old ones. Including
both 555 and 565 modes.
We drop the palette argument for pixmap construction as it was only
used for black/white anyway.
Canvas creation is simplified so that there is no separate set_mode
state. Canvases are already created in the right mode and never change.

This is pretty straightforward, although there are two weird issues.
The current encoder has two bugs in the yuv conversion. First of all
it switches red and blue, due to something of an endianness issue. We
keep this behavior by switching red and blue. Maybe we want to
change this in the new protocol version since switching this may
cause jpeg compression to be worse.
Secondly, the old coder/decoder did rgb to/from yuv420 wrongly for
jpeg, not using the "full scale" version of Y that is used in jpeg,
but the other one where y goes from 16 to 235. (See jpeg/jfif
reference on http://en.wikipedia.org/wiki/YCbCr for details.)
The new decoder uses the full range in order to get better quality,
which means old encoders will show slightly darker images.
This completely removes all ffmpeg usage in the client

Now we can send commands from the server to the client
to destroy surfaces (right now just the primary surface)
Needed for offscreens support)
Another patch`s on the way.

Top down streams arrive from x11-qxl driver.

This is an automatic change using:

Screen now have to modes locked and unlocked.
In unlocked mode, the application can change screen size and so
reduce resolution changing. The application can also choose to
change window size while not in full screen mode.
In locked mode the application must ewtain locker screen size
setting.

Just move around touch_context and untouch_context to be at the right
places.
