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().

* 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.
