The documentation for G_TYPE_CHAR says:
"The type designated by G_TYPE_CHAR is unconditionally an 8-bit signed
integer."
However the return value for g_value_get_char() was just "char" which
in C has an unspecified signedness; on e.g. x86 it's signed (which
matches the GType), but on e.g. PowerPC or ARM, it's not.
We can't break the old API, so we need to suck it up and add new API.
Port most internal users, but keep some tests of the old API too.

Based on a patch by Giovanni Campagna <gcampagna@src.gnome.org>
From discussion, GVariantIter is not useful for bindings, but
GVariantBuilder may be.

The grouping in files/headers is not used anymore, and
the function attributes neither. Adapt abicheck scripts
and .def file generation rules accordingly.
Since we added g_object_notify_by_pspec(), an efficient way to install
and notify properties relies on storing the GParamSpec pointers inside
a static arrays, like we do for signal identifiers.
Instead of multiple calls to g_object_class_install_property(), we
should have a single function to take the static array of GParamSpecs
and iterate it.

The g_object_bind_property_with_closures() function should set a
marshaller if the two GClosures don't have one already. This simplifies
the caller code and avoids duplication.
We need to add a new marshaller to the gmarshal.list matching the
signature of the GBindingTransformFunc function.
Since using the function pointer version muddles the memory management
requirements of language bindings, we should implement a GClosure-based
variant on top of g_object_bind_property_full().

GBinding is a simple, opaque object that represents a binding between a
property on a GObject instance (source) and property on another GObject
instance (target).

g_object_notify_by_pspec() will emit the "notify" signal on the given
pspec, short-circuiting the hash table lookup needed by
g_object_notify(). The suggested and documented way of using
g_object_notify_by_pspec() is similar to the way of emitting signals
with their ID.
Emission tests (with no handler attached to the notify signal) show a
10-15% speedup over using g_object_notify().

Bug 541208 – Functions to easily install and use signals without
class struct slot
* gobject.symbols
* gsignal.[ch] (g_signal_new_class_handler): the same as
_gtk_binding_signal_new(), to install signals with a callback
instead of a class struct slot as class closure.
The next two functions are C convenience and much easier to use
than the generic overriding and chaining APIs which are intended
primarily for language bindings:
(g_signal_override_class_handler): to override a signal with a
callback instead of a class struct slot.
(g_signal_chain_from_overridden_handler): to chain up from a
signal without class struct slot. The API is similar to
g_signal_emit().

Thu Dec 22 14:59:24 2005 Tim Janik <timj@imendio.com>
* gvaluetypes.[hc]: implemented G_TYPE_GTPYE. applied patch
from matthias which implements GType accessors for GValue.
* gparamspecs.[hc]: applied patch from matthias which
implements G_TYPE_PARAM_GTYPE.
* gobject.[hc]:
GUnowned: introduced a new object type that has an initially
floating reference.
g_object_compat_control(): allow setting of a floating flag handler.
Wed Nov 23 18:01:46 2005 Tim Janik <timj@imendio.com>
* gobject.[hc]: added floating reference count.
g_object_is_floating():
g_object_ref_sink(): new functions to deal with floating references.
g_object_force_floating(): new funciton for object implementations
to set the floating flag.
* gobject.c (g_object_init): make objects initially floating.
Wed Nov 23 17:58:13 2005 Tim Janik <timj@gtk.org>
* gparam.[hc]: added g_param_spec_ref_sink().
2005-07-11 Matthias Clasen <mclasen@redhat.com>
* gobject.h:
* gobject.symbols: Remove G_GNUC_NULL_TERMINATED from
g_object_new again, since that makes gcc warn on calls of
the form g_object_new (some_type, NULL)
2005-05-05 Owen Taylor <otaylor@redhat.com>
* gobject.[ch] gobject.symbols: Add
g_object_add/remove_toggle_ref() functions to get notification
when a reference count is the last remaining reference; this
enables better memory management for language bindings.
(http://mail.gnome.org/archives/gtk-devel-list/2005-April/msg00095.html)
2005-05-05 Owen Taylor <otaylor@redhat.com>
* glib/gdataset.[ch] glib/gdatasetprivate.h: Add
g_datalist_set/unset_flags(), g_datalist_get_flags() functions
to squeeze some bits into a GDataSet... this is needed for
efficient implementation of toggle references in GObject.
* tests/gobject/references.c tests/gobject/Makefile.am:
Add a test case for weak and toggle references.
* glib/gfileutils.[ch]: Rename g_file_replace() back
to g_file_set_contents().
* glib/glib.symbols: Update.
2005-05-05 Owen Taylor <otaylor@redhat.com>
* glib/Makefile.am glib/glib-sections.txt gobject/gobject-sections.txt:
Update
* gobject/tmpl/objects.sgml: Document toggle-references.
2005-03-14 Matthias Clasen <mclasen@redhat.com>
* abicheck.sh: Make work again.
* gsourceclosure.c: Fix a typo.
Make PLT-reduction work with gcc4, and don't include
everything in gobjectalias.h:
* gobject.symbols: Group symbols by header and source
file.
* makegobjectalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegalias.pl -def
* Makefile.am (gobjectaliasdef.c): Add a rule to
build this file.
* *.c: Include gobjectalias.h after the other i
GLib headers, include gobjectaliasdef.c at the bottom.
2004-11-23 Matthias Clasen <mclasen@redhat.com>
Fix a problem with the PLT reduction changes which caused the
internal aliases to lose all attributes.
* glib/glib.symbols: Add attribute annotations.
* glib/makegalias.pl: Keep attribute annotations, but strip PRIVATE.
* glib/Makefile.am (glib.def): Strip attribute annotations, but keep
PRIVATE.
2004-09-22 Tor Lillqvist <tml@iki.fi>
* Makefile.am (install-libtool-import-lib): [Win32] Add code to
remove the bug-compatibility entries (see #134813, and related
comments below) from the import library. The PRIVATE keyword in
the .def file is supposed to mean that, but it isn't implemented
yet by GNU ld.
* makegobjectalias.pl: In case the symbol is followed by some
stuff ("PRIVATE") that's intended for the .def file, use just the
actual symbol.
* gobject.symbols: For binary bug compatibility on Win32, add the
g_slist_remove_all and g_unichar_validate symbols inside #ifdef
INCLUDE_INTERNAL_SYMBOLS. (See #134813 and log entries from March
below.)
2004-09-16 Matthias Clasen <mclasen@redhat.com>
Add ABI control using the same technique that is used in GTK+.
* gobject.symbols: Master list of symbols.
* gobject.def: Removed. It is now generated from gobject.symbols.
* Makefile.am (gobject.def): Generate from gobject.symbols.
(TESTS): Add abicheck.sh
(EXTRA_DIST): Add abicheck.sh
(export_symbols): Don't export _-prefixed symbols.
* gtype.h:
* gtype.c: Move the declarations of the various _init() functions
to the header, and mark them as G_GNUC_INTERNAL.
