In a comparison with current autotools build system, meson/ninja
provides a huge improvement in build speed, while keeping the same
functionalities currently available and being considered more user
friendly.
The new system coexists within the same repository with the current one,
so we can do more extensive testing of its functionality before deciding
if the old system can be removed, or for some reason, has to stay for
good.
- Meson: https://mesonbuild.com
This is the equivalent of autogen/configure step in autotools. It
generates the files that will be used by ninja to actually build the
source code.
The project has received lots of traction recently, with many GNOME
projects willing to move to this new build system. The following wiki
page has more details of the status of the many projects being ported:
https://wiki.gnome.org/Initiatives/GnomeGoals/MesonPorting
Meson has a python-like syntax, easy to read, and the documentation
on the project is very complete, with a dedicated page on how to port
from autotools, explaining how most common use cases can be
implemented using meson.
http://mesonbuild.com/Porting-from-autotools.html
Other important sources of information:
http://mesonbuild.com/howtox.htmlhttp://mesonbuild.com/Syntax.htmlhttp://mesonbuild.com/Reference-manual.html
- Ninja: https://ninja-build.org
Ninja is the equivalent of make in an autotools setup, which actually
builds the source code. It has being used by large and complex
projects such as Google Chrome, Android and LLVM. There is not much to
say about ninja (other than it is much faster than make) because we
won't interact directly with it as much, as meson does the middle man
job here. The reasoning for creating ninja in the first place is
explained on the following post:
http://neugierig.org/software/chromium/notes/2011/02/ninja.html
Also its manual provides more in-depth information about the design
principles:
https://ninja-build.org/manual.html
- Basic workflow:
Meson package is available for most if not all distros, so, taking
Fedora as an example, we only need to run:
# dnf -y install meson ninja-build.
With Meson, building in-tree is not possible at all, so we need to
pass a directory as argument to meson where we want the build to be
done. This has the advantage of creating builds with different options
under the same parent directory, e.g.:
$ meson ./build --prefix=/usr
$ meson ./build-extra -Dextra-checks=true -Dalignment-checks=true
After configuration is done, we call ninja to actually do the build.
$ ninja -C ./build
$ ninja -C ./build install
Ninja defaults to parallel builds, and this can be changed with the -j
flag.
$ ninja -j 10 -C ./build
- Hacking:
* meson.build: Mandatory for the project root and usually found under
each directory you want something to be built.
* meson_options.txt: Options that can interfere with the result of the
build.

Following commit fcaf8d1a1, build from tarballs/make distcheck is broken
as spice-server-enums.h is not regenerated when building from tarballs,
and we don't have a -I$(top_srcdir) in our build flags, just
-I$(srcdir). This commit changes #include <server/spice-server-enums.h>
to #include <spice-server-enums.h> which avoids the problem fixed by
commit fcaf8d1a1 without breaking make distcheck.

When using #include "spice-server-enums.h", it will be looked up first
in the directory containing the file being build, which is going to be
$srcdir when dcc.c includes it. However, spice-server-enums.h is a
generated file, so it will be in $builddir, not in $srcdir. This most of
the time won't be causing any problems, except when you happen to have
an invalid spice-server-enums.h in $srcdir and you are doing an
out-of-tree build.
Using #include <spice-server-enums.h> instead allows the correct
spice-server-enums.h file to be looked up.

Rather than using
#ifdef COMPRESS_DEBUG
spice_info(...);
#endif
we can #define COMPRESS_DEBUG to spice_debug() or to do nothing for a
slight readability improvement. This opportunity is used to replace
these spice_debug() calls with g_debug(). The "do nothing" macro is a bit
convoluted to ensure that we will have a compile-time check for our
g_debug args.

There was a small regression introduced in get_compression_for_bitmap()
by f401eb07f dcc: Rewrite dcc_image_compress.
If SPICE_IMAGE_COMPRESSION_AUTO_GLZ is specified, and the bitmap has a
stride which is bigger than its width (ie it has padding), then
get_compression_for_bitmap() will return SPICE_IMAGE_COMPRESSION_OFF
while in that case, we used to use QUIC for compression.
This happens because that function in the AUTO_GLZ case first checks if
QUIC should be used, if not, it decides to use GLZ, but then decides it
can't because of the stride, so falls back to OFF, while it used to
fall back to QUIC.
This commit only slightly reworks a preexisting if (!can_lz_compress())
check so that it's unconditional rather than depending on the previous
checks having been unsuccessful.
This issue could be observed by using a spice-html5 without support for
uncompressed bitmaps with end-of-line padding by simply starting a f28
VM and connecting to it/moving the mouse cursor in it.

SPICE expects to have each frame in a single message.
So far the stream-device did not do that.
That works fine for H264 streams but not for MJPEG.
The client handles by itself MJPEG streams, and not via
gstreamer, and is assuming that a message contains the
whole frame. Since it currently not, using spice-streaming-agent
with MJPEG plugin, confuses the client which burns CPU
till it fails and keeps complaining:
"GSpice-CRITICAL **: 15:53:36.984: need more input data"
This patch fixes that, by reading the whole message from the
device (the streaming agent) and sending it over to the client.

self_bitmap flag is used for some complex drawing not possible
by QXL_DRAW_COPY commands. Having this flag set causes
spice-server do draw part of the screen, copy that part on new
allocated image and reduce network optimisations with no visual
changes.
Some drivers (like Windows 10 DOD) set this flag by mistake for
this command so reset it.
More details follow.
The self_bitmap flag is used for some drawing command requiring to mix
the frame buffer with some other image. For this specific
QXL_DRAW_COPY command self_bitmap is used by spice-server code during
cachine/sending (the reason for the cache is to cache images sent to
client so the relationship between the two parts of the code).
However the self_bitmap_image (an image created in spice-server if
this flags is set) is used only if src_bitmap of SpiceCopy structure
(the structure used to store the QXL_DRAW_COPY command inside
spice-server) is NULL. But in red_get_copy_ptr (red-parse-qxl.c, the
function that parse the QXL_DRAW_COPY command form the QXL device)
not having a src_bitmap is considered an error so the
self_bitmap_image won't be used.
Why this flag affects network performance?
When spice-server see this flag it update the frame buffer according
to the pending commands (commands to be sent or still to be drawn on
frame buffer). spice-server maintain a tree of commands used to reduce
rendering and command to send. More or less if a command is covering
other commands (for instance filling the entire screen with a single
color) the pending commands can be removed from the queue and not sent
to the client. However when an update of the frame buffer is requested
spice-server update the frame buffer removing the commands from the
tree but not from the client queue.
