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>.
