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

spice: fixed reference to xinerama pkg config file
(Xinerama.pc=>xinerama.pc)
Author: Yonit Halperin <yhalperi@redhat.com>
spice client and spice server shares code from
common/{gdi,gl,sw}_canvas.[ch]. However, while most of the code is
shared, the server code wants a canvas compiled with
SW_CANVAS_IMAGE_CACHE defined while the client code wants a canvas
compiled with SW_CANVAS_CACHE.
The initial autotools refactoring didn't take that into account,
this is now fixed by this commit. After this commit, the canvas
files from common/ are no longer compiled as part of the
libspice-common.la convenience library. Instead, there are "proxy"
canvas source files in client/ and server/ which #include the
appropriate C files after defining the relevant #define for the
binary that is being built.
To prevent misuse of the canvas c files and headers in common/,
SPICE_CANVAS_INTERNAL must be set when including the canvas headers
from common/ or when building the c files from common/ otherwise
the build will error out.
spice Makefile.am setup is a bit confusing, with source file
names being listed several times in different Makefile.am
(generally, once in EXTRA_DIST and another time in another
Makefile.am in _SOURCES). The client binaries are built
by client/x11/Makefile.am, which means recursing into client,
then into x11 to finally build spicec. This Makefile.am is
also referencing files from common/ and client/, which is
a bit unusual with autotools.
This patch attempts to simplify the build process to get
something more usual from an autotools point of view.
The source from common/ are compiled into a libtool convenience
library, which the server and the client links against which avoids
referencing source files from common/ when building the server and
the client. The client is built in client/Makefile.am and directly
builds files from x11/ windows/ and gui/ if needed (without
recursing in these subdirectories).
This makes the build simpler to understand, and also makes it
possible to list source files once, which avoids potential
make distcheck breakage when adding new files.
There is a regression in this patch with respect to
sw_canvas/gl_canvas/gdi_canvas. They should be built with
different preprocessor #defines resulting in different behaviour
of the canvas for the client and the server. However, this is not
currently the case, both the client and the server will use the same
code for now (which probably means one of them is broken). This will
be fixed in a subsequent commit.
make distcheck passes, but compilation on windows using the
autotools build system hasn't been tested, which means it's likely
to be broken. It shouldn't be too hard ot fix it though, just let
me know of any issues with this.
client/ contains several .cpp file which only #include a .c file
of the same name. This is unusual and seems to only be done to
get C++ name mangling on the symbols defined in the C file.
Now that all headers files in common/ use extern "C", these
wrappers are no longer useful.
The server Makefile.am rules for marshallers generation are
prefixed with AM_V_SILENT to integrate nicely with automake silent
rules. The same AM_V_SILENT prefix isn't used in client/Makefile.am
resulting in verbose output even when automake silent mode is
enabled. This commit removes this verbosity.
Spice client controller enables external control (e.g., by XPI or ActiveX) of
the client functionality.
The controller protocol enables setting parameters (host, port, sport, pwd,
secure channels, disabled channels, title, menus, hotkeys etc.), connecting
the server, showing and hiding the client etc.
The controller is based on the cross-platform named pipe.
Spice foreign menu enables external control of the client menu.
The foreignmenu protocol enables an external application to:
add a submenu, set its title, clear it, add/modify/remove an item etc.
Foreign menu is based on the cross-platform named pipe.
The OpenGL renderer isn't really useful right now, its not quite up
to date, its not really faster than software and it only supports a limited
subset of drivers. So, lets disable it for now.
Long term opengl rendering of the 2d part of spice is important if we want
to combine 2d and 3d rendering (say if spice adds opengl support in the
protocol). But until then this is isn't useful for normal use.
We move all message structs from spice-protocol to spice as
we want to be able to change these as needed internally. The
on-network format is no longer defined by these structures anyway,
but rather by the spice protocol description.
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.
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
Every place that does a regular malloc/calloc and aborts on failure
should use spice_malloc/spice_mallo0 instead, which is leaner and cleaner.
Allocations of dynamically sized arrays can use g_malloc_n or g_new etc
which correctly handle multiplication overflow if some of the arguments
are not trusted.
This includes:
* pixman region from SpiceRects
* rop2 enum
* solid fill
* solid fill with rop
* tiled fill
* tiled fill with rop
* blit
* blit with rop
* copy rect
The process loop is responsible for: 1) waiting for events 2) timers 3) events queue for
actions that should be performed in the context of the thread and are pushed from other threads.
The benefits:
1) remove duplicity: till now, there was one implementaion of events loop for the channels and
another one for the main thread.
2) timers can be executed on each thread and not only on the main thread.
3) events can be pushed to each thread and not only to the main thread.
In this commit, only the main thread was modified to use the new process loop.
