spice_common.h provides an ASSERT macro, no need to duplicate it
in many places. For now client/debug.h keeps its own copy since
debug.h and spice_common.h have clashes on other macros which are
trickier to unify.
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
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.
canvas_base.c tries to define PANIC, but it might already be set
if eg client/debug.h has been included before. All the other
macros in this file are guarded by #ifndef, this commit adds
the missing #ifndef to PANIC. Note that this is just a bandaid,
ideally common/ would contain a logging frameword, and these
macros would only be defined once instead of being defined in
several places.
Allow top_down flag to have any value, only ASSERT it is positive
when needs to be positive and zero otherwise. Allows older server
bug of sending 4 instead of 1 in top down flag to not affect newer
clients (previous patch fixes server).
Internally and in the network protocol (for the new version) we
now store the actual number of segments rather than the size of the
full segments array in bytes. This change consists of multiple changes
to handle this:
* Make the qxl parser calculate num_segments
* Make the canvas stroke code handle the new SpicePath layout.
* Fix up is_equal_path in red_worker.c for the new layout
* replace multiple calls to spice_marshall_PathSegment with a single
spice_marshall_Path call
* Make the byte_size() array size handling do the conversion from
network size to number of elements when marshalling/demarshalling.
* Update the current spice protocol to send the segment count rather than
the size
* Update the old spice protocol to use the new byte_size functionallity
to calculate the size sent and the number of elements recieved
red_parse_qxl.c starts to follow QXLPHYSICAL references and build up
data structures. Can zap a bunch of get_virt calls in red_worker.c,
followed by cleanups.
(de-) marshaller needs updates to deal with that. Also I suspect with
the get_virt() calls being gone we can offload more work to generated
marshaller code.
client doesn't build.
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.
1) add an option to determine if a bitmap can be sent lossy to the client
2) when required, replacing lossy cache items with their correspending
lossless bitmaps
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.
We rely on not passing on empty rects to the drawing operations by
checking for empty regions and exiting early. However the checks
were wrongly using pixman_region32_n_rects(region) == 0, whereas
we should be using pixman_region32_not_empty().
This adds a set of virtual methods for low-level operations. A subclass
can choose to implement those and let the default CanvasBase implementations
handle the highlevel stuff.
