Add a new type, "unix_fd", used to describe file descriptor sharing via
socket ancillary data (these messages are local only).
The marshaller/demarshaller can't serialize this in memory (consume_fd
implementation is empty), so it is the responsability of the marshaller
user to handle sending and receiving the handles, which are appended at
the end of the message with an extra stream byte (because some Unix
requires sending at least a byte with ancillary data).
Even if there is no fd to send (or if the fd is invalid etc), the
receiver side expects an extra byte anyway.

This reverts commit 7665dcf1bb2fa0b16b3d0015b28d7f5912664c3f.
Also revert the related build-sys changes to fix the build.
codegen generated code depends on spice-common code (marshaller,
messages etc), it makes more sense to keep the generator along
this. Otherwise a newer protocol release will fail to build older
projects.
*.proto files are required as well, since it generates code that parent
modules depend on unconditionnaly.

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',

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.

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.
|
|
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

The return of the get_array_size() is used as a limit in a loop,
being compared with an unsigned index (indexes are always unsigned).
To avoid the -Wsign-compare warning, let's cast the return of the
get_array_size() to unsigned and make GCC happier.
|
|
Although the most part of the parameters marked as unused are actually
being used for a few functions, a bunch of warnings can be seen when
the code is compiled with "-Wall -Wextra". As adding the unused attribute
means that the variable/parameter is meant to be *possibly* unused, we're
safe adding it in the generated code, even for used variables/parameters.

Since the (de)marshallers are now generated in $builddir and not in
$srcdir, when these generated files include a file located in
$srcdir/common, the compiler will find them thanks to a -I directive, so it
makes more sense to use <> rather than "" when including them.
|
|
Now that they are created in $builddir, their includes will need to refer
to files in $srcdir, which can be different. It's cleaner to add
-I $(top_srcdir)/spice-common/ to modules using spice-common rather than
having -I $(top_srcdir)/spice-common/common which would could create header
collisions.

The wireshark protocol dissector is a bit out-of-date. Several new channel types
and enums have been added. It would be nice if these values (and the
translation between the value and the name) could be automatically generated so
that updating the dissector was a slightly less manual process. This patch adds
a commandline switch which generates both the enums and value-name lists in the
format that wireshark expects.

broken enums generation
Fixes the resulting enums.h from the invocation of:
./spice_codegen.py --generate-enums spice.proto spice-protocol/spice/enums.h
Right now any enum will contain None as the enum members, with this fix
it will contain the real enum members, i.e. SPICE_FOO.

- autotoolize
- fix headers inclusion
- generate gitignores
- workaround serverSMARTCARD support with dirty hack...

Compile out part that we are not supporting. In the future, we might
want to declare a fake type and an empty function to keep API
compatibility
|
|
|
|
This solves the issue of struct_marshallers being included within the
current ifdef/endif body, although they are independant functions.
|
|
Before this patch, if a channel is defined conditionally in spice.proto
(because it depends on external headers like the smartcard channel),
spice_codegen would write an entry to the channels array in
spice_get_*_channel_parser which would only take up a place in the array
if the ifdef condition is true, thus moving up all other intializers
one place when it is not true. This was causing issues (crashes) when building
spice-gtk with the combination of usbredir support enabled and smartcard
support disabled.
This patch fixes this by adding #else { NULL, 0 }, to the generated code.

We want to be able to add an @ifdef annotation to optional messages
For example, we want to compile in the smartcard messages only if
libcacard is available
|
|
These methods will be needed to be able to make some fields optional
in spice.proto

|
|
A message with a fixed-size array, such as uint8 uuid[16] will
generate an invalid code, missing the __nelements variable. Make sure
that variable is defined.

With the new usbredir code we have the new concept of the abstract /
generic spicevmc channel type (which just tunnels data from a qemu chardev),
and we've the usbredir channel, which is the only current user of this.
This was reflected in the protocols enum in spice-protocol.h by a manual
edit done by me, my bad. This patch teaches spice.proto about the relation
between the abstract spicevmc channel and the usbredir channel and
modifies codegen to deal with this.

Check both in configure.ac (after checking if we need to rebuild
the marshalling files) and in the python script using pyparsing

Commit 9d5ef9beeca722b2ceff7d15aaa3aaaaf07ecfbf in spice-protocol
introduced a typedef manually in the generated enums.h header.
This patch adds them automatically to all enums during enums.h generation.

python_modules/demarshal.py and marshal.py fixes for gcc 4.6.0
warning about set but unused variables. The fixes disable creating
of variables mem_size when they are not used (demarshall) and
declaring a src variable when the message doesn't use it (marshal).
You need to touch *.proto after applying this (should add a Makefile
dependency).

Patch adds a "from __future__" import that doesn't affect newer python's but
allows python 2.5.4 to run the code (tested under scratchbox, n900 build environment)

It turns out that using base + sizeof(struct) is not a good way to
access an array at the end of a struct. For SpicePalette sizeof is 16, but
offset of ents is 12. Using this calculation in the demarshaller breaks
things badly, so now we use the actual array member.
