In mingw builds, this will be set to mingw-pkg-config rather than the
host system one. This is fixing a build failure on mingw when
spice-protocol is only installed in the mingw prefix and not
system-wide.

This allows to test the spice_marshaller_linearize() fix which was sent
recently.
|
|
The linearization optimization that avoids copying only one item must
check that there are no further marshallers in the chain.
Just to be clear, we are trying to marshall a message like this:
message {
uint32 data_size;
uint64 *data[data_size] @marshall;
} SomeData;
Where the data field points to an array in dynamic memory. Marshalling
and demarshalling functions look good. The marshalling function creates
a submarshaller for the data field and links it to the root marshaller.
But when it comes to sending the data through the wire, only the
data_size field gets sent. We have observed that, in
spice_marshaller_linearize, execution enters into the optimization that
avoids copying the data when the root marshaller only has one item, but
it ignores the following marshallers in the list. Checking if there are
more marshallers fixes the problem.

Now that spice-protocol ships the needed .proto files as well as the
corresponding python scripts, spice-common can use these in order to
generate the C code for the SPICE (de)marshallers.
|
|
spice-protocol is a separate project which is having releases, so there
is no need to have a private spice-protocol copy in each spice-common
user, especially as after installation, the system-wide spice-protocol
copy will be used instead of the private one the module was built
against.

This patch changes the type of 'valid_attributes' and
'attributes_with_arguments'.
Both of them are list of different strings and are kept in sets.
This was the intention of the original code, but this patch
use a specific set([ strings ]) format, instead of { strings }.
This fixes the build for me on RHEL-6 (python-2.6.6).
Build error is:
File "/home/ulublin/git/spice/spice-common/python_modules/ptypes.py",
line 67
'end',
^
SyntaxError: invalid syntax

This is to prepare to generate the wireshark dissector which uses
glib types instead of the newer C ones (for compatibility with some
compilers).

Verify that the attribute is known. This could help for instance to
avoid some future typo mistakes.
We also now have a list of attributes that we can comment for
documentation purpose.

Trying to generate enums.h with python3 results in
Traceback (most recent call last):
File "./spice_codegen.py", line 217, in <module>
write_enums(writer, options.generate_dissector)
File "./spice_codegen.py", line 99, in write_enums

if len(messages) == 0:
TypeError: object of type 'filter' has no len()
filter() returns an enumerator object in python3 while it used to return
a list in python2. Using list(filter()) instead fixes that error.
I've checked that the generated enums.h is identical with python2 and
python3.

There are 3 lines in spice.proto/spice1.proto which start with spaces
and then contain a tab. This commit removes the spaces and only keep the
tab.

This causes failures on EL6 otherwise as autoconf is too old there.

Runtime conversion from a string to uint32 is storing the magic with the same
endianness on both LE and BE machines. This requires aditional byte swap
when sending magic between LE/BE machines.
Changing quic magic to a constant will ensure, that it will be always stored in
native endianness, and the second byte swap won't be needed.

Commit d39dfbfe changes lz magic to be always treated as LE when encoded.

Update enums.h for preferred compression message
Add a preferred compression capability
|
|
When accessing a virtual desktop from different devices, some may have
different image compression requirements, e.g. slow devices may prefer
the faster LZ4 over GLZ. This message instructs the server to switch the
image compression algorithm. This patch also promotes the
SPICE_IMAGE_COMPRESS_* constants so that they are available from both
the server and the client.
|
|
It's not directly used by spice-common, but this way spice-gtk and
spice-server can share the same implementation.
|
|
This includes volume synchronization protocol;
|
|
Older versions of python-six (at least 1.3.0) defined six.PY3 but not
six.PY2. six.PY2 is only used twice in straightforward tests so it's
easy to use six.PY3 instead.
|
|
After the patch adding support for python 3 to the code generator,
python-six is required when building from git. Since I got 2 different
reports of SPICE build failures right after introducing it, it's
probably better to check for the needed python modules from configure,
and exit with an error if they are missing.
This commit adds a --enable-python-checks configure flag for that
though, since we only want to do that when building from git. It assumes
that people running from git will be running autogen.sh, while people
building from tarballs will run configure.

A few files (the generated marshalling code and pixman-related utils)
make use of WORDS_BIGENDIAN in order to do the right thing depending on
endianness. configure.ac must call AC_C_BIGENDIAN for it to be defined.

This is a new version of my previous patch that does not include six.py.
It's still kind of big, but at least it's all spice-common changes now.
There are also a few other fixes that Christophe brought to my attention.
Note that six now needs to be installed on the system (python-six on
Fedora and Debian, six on PyPI).
This *should* be enough to make spice_codegen.py work on both Python 2
and Python 3. The major changes are as follows:
* cStringIO.StringIO -> io.StringIO
* str vs. unicode updates (io.StringIO doesn't like str)
* integer division
* foo.has_key(bar) -> bar in foo
* import internal_thing -> from . import internal_thing
* removed from __future__ import with_statement
(might break Python 2.5?)
* changed some lambdas to list comprehensions (done by 2to3)
* cast some_dict.keys() to list where needed (e.g. for sorting)
* use normal type names with isinstance instead of types.WhateverType

Both wincrypt.h and openssl try to define X509_NAME. The wincrypt.h one
is not useful for us, so we currently #undef it if this was set.
However, it's done very late, right before including x509v3.h which
defines the X509_NAME type. Any header included in between may try to
#include x509v3.h so it's better to undefine X509_NAME right after
including wincrypt.h.

Every time it's used, it's in constructs similar to:
#ifdef SW_CANVAS_CACHE
, SpiceImageCache *bits_cache
, SpicePaletteCache *palette_cache
#elif defined(SW_CANVAS_IMAGE_CACHE)
, SpiceImageCache *bits_cache
#endif
This can be rewritten as:
, SpiceImageCache *bits_cache
#ifdef SW_CANVAS_CACHE
, SpicePaletteCache *palette_cache
#endif
allowing to get rid of SW_CANVAS_IMAGE_CACHE.

Fix the row alignment for 16/24 bpp images when it is not in a 32bit
boundary. This is needed for 16bpp images when the width is an odd
number, and for the future support of 24bpp images.

Adjust the way the top_down flag is read to the corresponding change in
the wire protocol.

SW_CANVAS_CACHE is always defined when building spice-gtk,
SW_CANVAS_IMAGE_CACHE is always defined when building spice-server, and
they are the only 2 users of spice-common. Moreover, build when none of
these is defined is broken.

All canvas_get_{quic,jpeg,lz4,jpeg_alpha,lz} methods have an 'invers'
argument, but are always called with that argument being 0, so we can
drop it from the argument list, and remove the code triggerring when
it's true.
