Basically due to a combination of va_args semantics around
signed/unsigned ints, this test case fails on ppc64. At the moment,
we have as yet to find any real-world consumer with such a large

Unfortunately, the possible fixes for this are extremely invasive;
we would have to define a new enum API.
Given both of these facts, we believe it makes the most sense at the
current time to simply not test this. If we at a later time determine
there is such a real-world consumer, we can look at doing the
necessary fixes.

Modify gsignal to automatically disconnect a GClosure that becomes
invalid (in the g_closure_invalidate() sense).
Previously, when g_signal_connect_object() was used with a GObject as
the user_data and that object was destroyed, the handler would no longer
be called but the signal handler was itself was not disconnected (ie:
the bookkeeping data was kept around).
The main effect of this patch is that these signal handlers will now
be automatically disconnected (and fully freed).
The documentation for g_signal_connect_object() has anticipated this
change for over 10 years and has advised the following workaround when
disconnecting signal handlers connected with g_signal_connect_object():
if (g_signal_handler_is_connected (instance, id))
g_signal_handler_disconnect (instance, id);
If your code follows this practice then it will continue to work.
If your code never disconnects the signal handler then it was wasting
memory before (and this commit fixes that).
If your code unconditionally disconnects the signal handler then you
will start to see (harmless) g_critical() warnings about this and you
should fix them.

This patch solves two problems:
First, it allows builders to optionally cut the circular dependency
between dbus and glib by disabling the modular tests (just like how
the tests can be disabled in dbus).
Second, the tests are entirely pointless to build if cross-compiling.
It also moves us slightly closer to the long term future we want where
the tests are a separate ./configure invocation and run against the
INSTALLED glib, not the one in the source tree. This would allow us to
run the tests constantly, not just when glib is built.

The trace of the signal emission of the was calculating the instance
type after the instance was unrefed. Fix this by keeping the instance type around.
The ability to cross-compile glib got broken after the
merge of the 'signal-performance' branch as the assumption
was made that the generated glib-genmarshal can be executed
on the host (which isn't valid when cross-compiling).
Fixed this by using the just-built glib-genmarshal for normal
compilations and the native (host) glib-genmarshal when doing a
cross-compilation as was also done in several other areas of GLib
Tested for host=x86_64-unknown-linux-gnu, target=x86_64-unknown-linux-gnu

In the code generation portion, va_copy() is not universally available,
so use the existing G_VA_COPY macro that in turn calls va_copy() if it
is available or call an appropriate emulation otherwise.
va_vopy() is not universally available in all compilers, so make use of
the existing G_VA_COPY macro which either calls va_copy() if it is
available, or emulates it if otherwise.
When there is only one closure handling a signal emission and
it doesn't have a bunch of complicated features enabled we
can short circuit the va_args collection into GValues and call the
callback via the va_marshaller directly.
https://bugzilla.gnome.org/show_bug.cgi?id=661140
If the signal argumment types matches a built in standard
marshaller we use the va_marshaller for that, and also the
normal marshaller if NULL was specified (as its faster than
the generic one).
This lets you set a va_marshaller on your signal which will be
propagated to all closures for the signal. Also, automatically
uses the generica va_marshaller if you specify a NULL c_marshaller.

This means we're not abusing the notifiers for meta_marshallres,

The GValueArray type was added in a time, during the Jurassic era or so,
when GArray did not have a representable GType. The GValueArray API has
various issues as well:
- it doesn't match the other GLib array types;
- it is not reference counted;
- the structure is fully exposed on the stack, so it cannot be
extended to add reference counting;
- it cannot be forcibly resized.
The nice thing is that now we have a GArray type that can replace in
full GValueArray, so we can deprecate the latter, and reduce the
complexity in GLib, application code, and bindings.

We were previously preventing implementations of an interface from
specifying G_PARAM_CONSTRUCT for a property of that interface if the
interface didn't specify it itself (or was readonly).
This is something that should only interest the implementation, so we
remove this restriction.
This allows 6 new possible override scenarios:
- writable -> writable/construct
- writable -> readwrite/construct
- readwrite -> readwrite/construct
- writable/construct-only -> writable/construct
- writable/construct-only -> readwrite/construct

The property override typecheck was meant to enforce the type on the
overriding property being exactly equal to the type on the interface
property. Instead, g_type_is_a() was incorrectly used.
We could try to enforce equality, but if a property is read-only then it
should be possible for the implementation to type the property with any
subtype of the type specified on the interface (because returning a more
specific type will still satisfy the interface). Likewise, if the
property is write-only then it should be possible for the implementation
to type the property with any supertype.
We implement the check this way.
https://bugzilla.gnome.org/show_bug.cgi?id=666616
Simplify some of the logic in this function.
1) Simplify flag checks as per Colin's suggestions in
https://bugzilla.gnome.org/show_bug.cgi?id=605667
2) Don't repeatedly recheck if class_pspec is NULL.
GObject enforces the following restrictions on property overrides:
- must only add abilities: if the parent class supports
readability/writability then the subclass must also support them.
Subclasses are free to add readability/writability.
- must not add additional restrictions: if the parent class doesn't
have construct/construct-only restrictions then the subclass must
not add them. Subclasses are free to remove restrictions.
The problem with the previous implementation is that the check against
adding construct/construct-only restrictions was being done even if the
property was not previously writable. As an example:
"readable" and "writable only on construct"
was considered as being more restrictive than
"read only".
This patch tweaks the check to allow the addition of
construct/construct-only restrictions for properties that were
previously read-only and are now being made writable.

When the 'conditional' parameter is TRUE, the queue will only be frozen
(ie: have its freeze count increase by one) if it is already frozen.
This will allow us to avoid a freeze-notify-thaw in the case that we
just want to notify on a single property.
Another approach may have been to add an is_frozen() type call and avoid
even increasing the freeze count at all in this case. Unfortunately,
I'm not totally sure what is the exact expected semantics of
simultaneous notifications in multiple threads and this may interact
badly with someone freezing or thawing in between our check and
emission.
Lift the check-if-READABLE and redirect-target logic from out of
g_object_notify_queue_add() into its own function, get_notify_pspec().
Use that function at the site of our two calls to
g_object_notify_queue_add().
This was done as a separate file before, and #include brought it into
gobject.c. That's a bit mad, so stop doing that.
Unfortunately, the insanity steps up a level: gobjectnotifyqueue.c is
installed in the public include dir, so we can't just get rid of it
entirely.
Similar to G_PARAM_DEPRECATED. It will warn only for users of the

This was used as an optimisation for the macro hackery that used to live
in gthread.h. If a particular library or program knew that it could
rely on thread support being enabled, it would allow for static
evaluation of conditionals in some of those macros.
Since the macros are dead and thread support is now always-on, we can
get rid of this bit of legacy.
And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().
Change the wording in the docs. Clarify expectations for
(deprecated) g_thread_create().
enums are stored in v_long but need to be marshalled as signed
integers. On platforms where int is 32 bits, taking the
address of v_long resulted in the wrong 32 bits being marshalled.
So we need to stuff the enum's int-sized value to a temporary
int-sized variable and marshall that instead.
Second, on return, libffi actually returns a pointer to a value
that's sized according to platform conventions, not according to
what the caller requested. ie if ffi_type_sint was requested, the
value can still be a 64-bit sign-extended long on a 64-bit
architecture like PPC64, thus the caller cannot simply cast
the return value as a pointer to the desired type, but must cast
as a pointer to an integral type and then cast to the desired
type to remove any sign extension complications.
For more information on how to correctly handle libffi return
values, see the following bug, specifically comment 35:
https://bugzilla.redhat.com/show_bug.cgi?id=736489
"For 64-bit ABIs that extend integral returns types to 64-bits, libffi always
returns full 64-bit values that you can truncate in the calling code. It's
just the way it is has always been. Please don't change libffi. I'll document
this clearly for the next version (perhaps there is a mention of this, I
haven't looked yet).
The same is true for returning 8-bit values, for instance, on 32-bit systems.
All ABIs extend those results to the full 32-bits so you need to provide a
properly aligned buffer that's big enough to hold the result."

The implementation of GValue is not public or documented. When

- update glib.symbols and documentation sections files
Closes#650823 and #650935
The grouping in files/headers is not used anymore, and
the function attributes neither. Adapt abicheck scripts
and .def file generation rules accordingly.
The hash table used exclusively for looking up types by name used to map
quarks => types. But we can easily make it map strings => types, which
avoids the quark lookup. And that in trun avoids taking a lock and
consulting another hash table. So this change should make
g_type_from_name() roughly twice as fast.
In some cases, signal arguments have to be collected, even if there are i
no signal handlers connected (e.g. for GVariant parameters, where collection
consumes a floating variant).
Based on a patch by Christian Persch.
Bug #643624.
These are the updates to the autotools files to
ensure the expansion of the GIO, GLib and GObject
project files (*.vcxproj, *.vcxproj.filters) and to
enable the distribution of the VS2010 project files
The actual VS2010 project files will follow shortly
