* generator/CallbackGen.cs: connect return value count parameters
* generator/ManagedCallString.cs: out count params aren't special
* generator/MethodBody.cs: don't finish hidden params
* generator/Parameters.cs: explicit IsCount setting support, with
Parameters.GetCountParameter(name) interface. Clear IsCount
values during validation if they have no associated array. Any
remaining count params must be associated with a retval, so
hide them.
* generator/ReturnValue.cs: support array_length_param attribute to
associate a return value with a "count" param. Use new helper
methods to marshal these array retvals to IntPtr and back.
* glib/Marshaller.cs: support for byte[] marshaling to and from
IntPtr using a count and type in the from native direction.
* gtk/Gtk.metadata: mark TextBufferSerializeFunc return type as
an array with the length specific in the length param.
The replaced code fails because sizeof(GValue) is 20 on 32 bit
linux but Marshal.SizeOf(GLib.Value) reported 24. If it aint broke,
don't fix it, and the long works on 32 and 64 in 2.12 and earlier.
* glib/Object.cs: move finalization queue to ToggleRef and make
Dispose() non-virtual with a protected virtual Dispose(bool).
Also added a WarnOnFinalize static property to produce nags for
undisposed objects.
* glib/ToggleRef.cs: add finalization queue and QueueUnref method.
* gtk/NodeStore.cs: override Dispose(bool)
* gtk/Widget.custom: override Dispose(bool)
* gdk/Display.custom: rework signal connection
* gdk/Window.custom: rework signal connection

* glib/Object.cs: add (Add|Remove)SignalHandler methods and use
them for the Notify connections. Move to generic collections for
everything but the Data hash.
* glib/Signal.cs: kill Lookup methods and add delegate fields
* glib/ToggleRef.cs: remove Signals hash, it doesn't belong here.

* glib/PtrArray.cs:
* glib/SignalClosure.cs:
* glib/Value.cs:
mark private struct fields public to avoid 0169, and remove the nowarn
from the csc command. fixed one real warning, exposed a bunch of
obsolete usage still to fix.
* generator/SymbolTable.cs : add GVariant type mapping.
* glib/Variant.cs: initial implementation of an opaque class to expose
the GVariant type from glib. We won't make any attempt to combine managed
references since there is no "toggle" ref capability. We'll do a one-to-one
ref_sink/unref pair on construction/dispose.
* AssemblyInfo.cs.in: kill keyfile attr
* Makefile.am: moved mono.snk to cairo dir
* Makefile.include: no need to copy snk into builddir any longer.
* cairo/AssemblyInfo.cs: kill keyfile attr
* cairo/Makefile.am: snk relocated into here. use it directly.
* glib/Makefile.am: no need to copy snk into builddir any longer.
* gtkdotnet/Makefile.am: no need to copy snk into builddir any longer.

* removed the glade dir from the build since libglade is
no longer supported in gnome3. removed the gapi2-compat stuff
since it doesn't make much sense now. Removed the bootstrap
mechanism since we are unlikely to be releasing multiple API
versions from the same tree going forward. The build is now a
straight autogen.sh like most autotools projects.
* glib/glue/Makefile.am: fix a copy/paste issue.
* pango/glue/Makefile.am: move glue lib to -3 like the others.
[Fixes#561148]

* glib/Idle.cs:
* glib/Timeout.cs: Don't try to remove the handler from the managed
hashtable twice, add a comment explaining the need for the else branch.
svn path=/trunk/gtk-sharp/; revision=142364
* glib/Idle.cs:
* glib/Timeout.cs: Make sure to remove the unmanaged reference to the
delegate when we're disposed or finalized. In particular, this fixes a
problem where GLib.Object's PerformQueuedUnrefs was being called after
both the object and the handler had been GC'ed, resulting in a
segfault.
svn path=/trunk/gtk-sharp/; revision=142362
* glib/Object.cs: add support for native instantiation of
managed types.

unmanaged instantiation capability.
Based on a patch from Sebastian Dröge [Fixes#499900]
svn path=/trunk/gtk-sharp/; revision=141819
* glib/Global.cs: Kill the calling convention field again.
It breaks GLib 2.x compatibility in the generator and there is
probably no need to make the calling convention configurable.
* .cs, *.custom: Hardcode Cdecl calling convention instead of
using GLib's field.
svn path=/trunk/gtk-sharp/; revision=141283
* glib/Global.cs: Add a public constant field specifying the
calling convention used by GLib and depending libraries.
By now it's hardcoded to Cdecl as every non-Win32 runtime
should ignore this attribute.
* *.cs, *.custom: Use GLib.Global.CallingConvention for both
pinvokes and callbacks. Plugs a stack leak on Win32. All
pinvokes defaulted to StdCall and thus the stack was never
cleaned up.

svn path=/trunk/gtk-sharp/; revision=131835
Add support for virtual methods(vm) to the generator.
* parser/gapi2xml.pl: Generate a class_struct element with

return type mangling to avoid custom implementations.

svn path=/trunk/gtk-sharp/; revision=121990

* Makefile.am:
* glib/Format.cs: new class to map the g_format methods
svn path=/trunk/gtk-sharp/; revision=119630
* glib/GType.cs: kill the FindTypeInReferences recursive loading
algorithm and instead do a name-based search through the references
of loaded assemblies only. Fixes the original bug #400595 and it
hopefully will have fewer sideeffects that the recursive loading
approach.
svn path=/trunk/gtk-sharp/; revision=114008
* glib/GType.cs: just fail on location null or empty instead of
checking the assembly type. Avoids failures on the ms runtime.
svn path=/trunk/gtk-sharp/; revision=113989
* glib/GType.cs (FindTypeInReferences): Put a try-catch around the assembly
loading as failure to load a referenced assembly is not really an error.
svn path=/trunk/gtk-sharp/; revision=112905

handle assemblies located in the same directory as the referring
assembly. Fixes#423450.

* generator/ReturnValue.cs: use new ListPtrToArray marshaler for
lists with known element types.
* glib/Marshaller.cs: new ListPtrToArray marshaller with more
aggressive list disposal.
* gtk/Container.custom: remove manual Children impl. Use Children
in GetEnumerator instead of pinvoking directly.
* gtk/Gtk.metadata: remove hidden attr and add element type and owned
for Container.GetChildren to generate it properly.
svn path=/trunk/gtk-sharp/; revision=111173
* glib/SignalClosure.cs: post back the gvalues after the closure is
invoked using a new Update method on GLib.Value. This only impacts
boxed types, since they are the only "value types" passed by ref in
the signal marshaling environment. We can't call set_boxed on the
value to update it, since that allocs new memory, we need to marshal
the updated struct out to the existing native memory address using
g_value_get_boxed.
* glib/Value.cs (Update): new update method for writing values to
an existing boxed type instance instead of allocating a new native
struct. Fixes#398929.
svn path=/trunk/gtk-sharp/; revision=106058
* glib/glue/object.c: fixes for object, boxed, and gtype
property paramspec creation. Patch provided by Christian Hoff.
svn path=/trunk/gtk-sharp/; revision=105905
Initial Patch submitted by Christian Hoff with some small
style alterations and a round trip sample by me. Supports the
registration of managed properties with the GType system, so
that things like custom cell renderers can be accessed via the
native property system from treeview.
* glib/glue/object.c : property registration related glue.
* glib/Object.cs: implement managed property registration.
* glib/PropertyAttribute.cs: add new props and ctor for managed
property registration.

tripping of registered properties.

* glib/Object.cs: revert the connection optimization from r102349.
It breaks under the current CellRenderer implementation which probably

the cast apparently has issues on bleeding edge mono.
svn path=/trunk/gtk-sharp/; revision=102693
* glib/Object.cs: Don't bother hooking VM into the class field
if another managed ancestor has already done so. Add a LogFunc
printing a stack trace for the GObject log domain if GTK_SHARP_DEBUG
is set in the environment. It's a bit noisy to do unconditionally.
