spice_server_destroy calls reds_exit which is called also at exit time
(is registered with atexit) so avoid to keep dangling pointers.
Currently this does not happen as spice_server_destroy is not called
by Qemu.

On 32 bit machine timespec->tv_sec (time_t) is 32 bit.
Also 1000 * 1000 * 1000 is 32 bit.
The multiplication of 2 32 bit integers gives a 32 bit integer, however
this can overflow.
Converting the first factor to 64 bit before the multiplication solves
the issue.

This script was used at make distcheck time to verify consistency of the
version number defined in configure.ac and in spice-server headers.
Since commit ab12cf414c, these 2 version numbers can no longer be out of
sync, so we can drop this script.

Commit 3c6b4e41 removed spice-experimental.h as this header was not
used, nor supposed to be used. However, QEMU had been including it
(without using any of its symbols) until commit v2.3.0-rc0~135^2~1
As this is fairly recent (Nov 2014), building older QEMUs with new
spice-server releases, or even bisecting QEMU will be broken as they
will be looking for a no-longer available header.
This commit readds a spice-experimental.h file, however it only contains
a #warning indicating this file is deprecated. This means older QEMU
will build now, but only if they were configured with --disable-werror.

spice-server headers expose SpiceImageCompression which is only available
from recent spice-protocol releases.
This dependency must be expressed in Requires and not Requires.private
|
|
Actually not causing problems as when used is always followed by another
terminator but better to fix the definition.

usage: spice-server-replay -p <port> -c <client command line> <cmdfile>
will run the commands from cmdfile ignoring timestamps, right after a
connection is established from the client, and will SIGINT the client
on end of cmdfile, and exit itself after waiting for the client.
spicy-stats from spice-gtk is useful for testing, it prints the summary
of the traffic on each channel.
You can also run with no client by doing:
spice-server-replay <cmdfile>
For example, the 300 MB file (compressed to 4 MB with xz -9) available
at [1] produces the following output:
spicy-stats total bytes read:
total bytes read:
inputs: 214
display: 1968983
cursor: 390
main: 256373
You could run it directly like so:
curl http://annarchy.freedesktop.org/~alon/win7_boot_shutdown.cmd.xz | \
xzcat | server/tests/spice-server-replay -p 12345 -c `which spicy-stats` -
Known Problems:
* Implementation is wrong. Should do a single device->host conversion
(i.e. get_virt), and then marshall/demarshall that (i.e. RedDrawable).
* segfault on file read done resulting in the above spicy-stats not
being reproducable (well, up to 1% yes).

Now based on glib including using an asyncqueue for reading the playback
file, and proper freeing of the allocated commands, with --slow,
--compression and a progress timer, and doesn't use more then nsurfaces.

if the environment variable in the title is set and can be
opened for writing a log of all display commands (no cursor
commands yet) and any QXLWorker calls (particularily primary
create and destroy) will be logged to that file, and possible
to replay using the replay utility introduced later.
For an example file (4 MB download, 300 MB after unpack with xz,
these 300 MB are themselves reduced from 1.2GB using zlib compression
for any chunk):

Currently hand crafted with some sed scripts and alot of vim macros from
red_parse_qxl after considering the logger in qemu/hw/qxl-logger.c and seeing
it was incomplete. The only problem with logging from the server and
not from qemu is that it requires coordinated shutdown to avoid half a message.
Should be automatically generated from a declarative syntax, i.e. qxl.proto.
Note: zlib compression is introduced in a disabled state, see ZLIB
define
Now with a simple versioned header and generated ids by the server
instead of based on the recorded file, and doesn't use more then 1024
surfaces (configurable).

It's #define'd to 'inline', and only used in the GLZ encoder.
|
|
It's seeing regular releases and is API stable, so we don't need to
bundle it with spice-server

As the input line could be uint8_t*, uint16_t* or uint32_t*, changing
the default from uint8_t* to void* seems the correct choice to deal with
upcasting warnings.
Regarding chunks->data allocation, I quote Frediano explantion:
"Lines came from spice_bitmap_get_line. This function assume that bitmap
data is split among chunks each containing some lines
(always full lines). If chunk->data is allocated using malloc or similar
SHOULD (not 100% sure) be 4 bytes aligned so in our cases
(8, 16, 24 or 32 bit images) should be aligned enough.
All the casts unfortunately came from the fact we compute based on
pixel bytes to make it generic so we use uint8_t*."
and
"Looking at code looks like these chunks came from the virtual machine.
So the question is... why should the virtual machine give use some
not-pixel align data?
I would put a large comment to state that we assume VM send aligned
data, would be stupid for the VM to not align it!"
clang output:
jpeg_encoder.c:109:26: error: cast from 'uint8_t *'
(aka 'unsigned char *') to 'uint16_t *' (aka 'unsigned short *')
increases required alignment from 1 to 2 [-Werror,-Wcast-align]

Instead of using uint8_t* which can cause several warnings on casting as
the example below:
./glz_encode_tmpl.c:321:29: error: cast from 'uint8_t *'
(aka 'unsigned char *') to 'rgb16_pixel_t *' (aka 'unsigned short *')
increases required alignment from 1 to 2 [-Werror,-Wcast-align]
ref_limit = (PIXEL *)(seg->lines_end);

that.

SpiceBitmap's stride is uint32_t.
from clang:

This is the place that needs the complete type definition. If it is
defined in reds.h, it can create circular references.
|
|
It doesn't make much sense to have static function declarations in a
header, even a private header. So move them down into the source file.

There is a red_init() methods, we can group all the red_init_*() calls
in it rather than calling red_init() followed by all these calls in our

This has been renamed to SpiceImageCompression in order to avoid clashes
with older spice-server in the SPICE_IMAGE_COMPRESS_ namespace. This
commit is a straight rename of SpiceImageCompress to
SpiceImageCompression and SPICE_IMAGE_COMPRESS_ to

This prevents a compile error on Debian Jessie, from git, such as this:
/usr/bin/ld: test_playback.o: undefined reference to symbol 'sin@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line
This is fairly subtle, and Debian specific. It only happens when you use
autoreconf to generate a new libtool script. Debian patches that script
to require an explicit setting to link with all dependent libraries.
It should be harmless on other distros, and it does save us Debian guys some
hassle.

new one
If a previous Qemu executable is not able to delete the statistic file
on the next creation with same name (statitics file are based on pid
numbers so if pid get reused for another Qemu process you get the same
name) it fails as you can't open a file with 0444 permissions (these
are the permission used to create these files).
This patch assure there are no stale file trying to remove it before the
creation of the new one. As file is based on pid and name used for spice
you are not deleting another file.

NET_TEST_WARMUP_BYTES is 0 so the warmup ping is the same as the one we
use to measure the latency. Even if it was not, the actual latency would
be the MIN() of both anyway so we might as well use both roundtrip times
to ward off latency jitter a bit.

red_marshall_image() allows to use other than QUIC compression only
when auto_lz or auto_glz image compression is set. Other images don't

Locking the individual calls that access the pixmap cache in fill_bits is
not adequately thread safe. Often a windows guest with multiple monitors
will be sending the same image via different threads. Both threads can
be in fill_bits at the same time making changes to the cache for the same
image. This can result in images being deleted before all the client
channels are finished with them or with the same image being send multiple
times. Here's what can happen with out the lock in fill_bits
On the server in red_worker.c:fill_bits
Thread 1 calls pixmap_cache_hit for Image A and finds it isn't in cache
Thread 2 calls pixmap_cache_hit for Image A and finds it isn't in cache
Thread 1 adds Image 1 to pixmap_cache (1x)
Thread 2 adds Image 1 to pixmap_cache (2x)
On the client
Channel 1 adds Image A to image_cache (1x)
Channel 2 replaces Image A in image_cache (1x)
On server
Thread 1 sends Image A rendering commands
Thread N removes Image A from pixmap_cache (image remains - 1x)
Thread 2 sends Image A rendering commands
On client
Channe1 renders from Image A
Channel N removes Image a from image_cache (image is completely removed)
Channel2 render command hangs waiting for Image A
