changed prototype of g_boxed_type_register_static() to contain an optional

Browse Source 
Wed Mar  7 09:36:33 2001  Tim Janik  <timj@gtk.org>

	* gboxed.[hc]: changed prototype of g_boxed_type_register_static()
	to contain an optional init function and a hint at whether the
	boxed structure uses ref counting internally.
	added g_value_set_boxed_take_ownership().
	made G_TYPE_BOXED an abstract value type.

	* genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value
	types.

	* glib-genmarshal.c: argument type changes, preparation for third-party
	arg specification.

	* gobject.[hc]: cleaned up get/set property code.
	added g_strdup_value_contents() to improve warnings.

	* gparam.[hc]: added g_param_value_convert(), taking over responsibility
	of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
	validation alterations may be valid a part of the property setting
	process.

	* gparamspecs.[hc]: made value comparisons stable (for sort applications).
	added GParamSpecValueArray, a param spec for value arrays and
	GParamSpecClosure. nuked the value exchange functions and
	GParamSpecCCallback.

	* gtype.[hc]: catch unintialized usages of the type system with
	g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT
	to flag types that introduce a value table, but can't be used for
	g_value_init(). cleaned up reserved type ids.

	* gvalue.[hc]: code cleanups and saner checking.
	nuked the value exchange API. implemented value transformations, we
	can't really "convert" values, rather transforms are an anylogy to
	C casts, real conversions need a param spec for validation, which is
	why g_param_value_convert() does real conversions now.

	* gvaluearray.[hc]: new files that implement a GValueArray, a struct
	that can hold inhomogeneous arrays of value (to that extend that it
	also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
	this is exposed to the type system as a boxed type.

	* gvaluetransform.c: new file implementing most of the former value
	exchange functions as single-sided transformations.

	* gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added
	g_value_set_string_take_ownership().

	* *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/.

	* *.[hc]: many fixes and cleanups.

	* many warning improvements.

Tue Feb 27 18:35:15 2001  Tim Janik  <timj@gtk.org>

	* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
	into G_VALUE_LCOPY(), this needs proper documenting.

	* gparam.c: fixed G_PARAM_USER_MASK.

	* gtype.c (type_data_make_W):
	(type_data_last_unref_Wm): fixed invalid memory freeing.

	* gobject.c (g_object_last_unref): destroy signal handlers associated
	with object, right before finalization.

	* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
	that don't actually support details.

	* gobject.[hc]: got rid of property trailers. nuked GObject
	properties "data" and the "signal" variants.
	(g_object_connect): new convenience function to do multiple
	signal connections at once.
	(g_object_disconnect): likewise, for disconnections.

	* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.

	* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
	as private (the latter got renamed from g_value_get_as_pointer()).

Wed Mar  7 09:32:06 2001  Tim Janik  <timj@gtk.org>

        * glib-object.h: add gvaluearray.h.

        * gstring.[hc]: fixup naming of g_string_sprint*.

        * gtypes.h: fixed GCompareDataFunc naming.

Wed Mar  7 09:33:27 2001  Tim Janik  <timj@gtk.org>

        * gobject/Makefile.am: shuffled rules to avoid excessive
        rebuilds.

        * gobject/gobject-sections.txt: updates.

        * gobject/tmpl/*: bunch of updates, added another patch
        from Eric Lemings <eric.b.lemings@lmco.com>.
