e773d7dba6 fixed dealing with collection/lcopy of NULL values.
Mon Dec 11 04:44:11 2000  Tim Janik  <timj@gtk.org>

	* gboxed.c: fixed dealing with collection/lcopy of NULL values.

	* gclosure.h: removed insane ramblings, added G_CALLBACK() a casting
	convenience macro.

	* Makefile.am: cleanups, marshaller generation rules.

	* gmarshal.[hc]: new files with GRuntime standard marshallers.

	* glib-genmarshal.c: fix log domain, support gruntime standard
	marshallers, suport G_TYPE_PARAM, come with extern "C" and
	#include gmarshal.h.

	* glib-genmarshal.1: reflect glib-genmarshal.c updates.

	* gobject.[hc]: implement object constructor. rework parameter
	changed notification queueing, we support queue freezes now and
	don't dispatch from an idle handler anymore.
	parameter->property rename hassle.
	implemented ::properties_changed and ::notify::* signals for
	property change notification (the later supports property names
	as details). added signal connection and named data properties.
	(g_signal_connect_object): new function to setup while_alive
	connections.
	(g_object_class_install_property): sink properties now, since they
	are initially floating.
	(g_object_steal_data):
	(g_object_set_data_full):
	(g_object_set_data):
	(g_object_get_data): set/get data by using g_datalist_*() functions
	directly.
	(g_object_queue_param_changed): nuked.
	(g_object_freeze_notify): start queueing of property changes (freeze/
	thaw calls stack).
	(g_object_notify): announce changes of a certain property directly.
	(g_object_thaw_notify): process queue of property changes, therefore
	emitting GObject::notify::detail with detail being the changed
	properties names.
	(G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former
	G_WARN_INVALID_PARAM_ID().

	* gparam.[hc]: param specs are now initially floating and need to be
	sunken with g_param_spec_sink(), support G_TYPE_PARAM values.
	added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags,
	required by GObjectClass.constructor().

	* gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and
	GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER
	and G_TYPE_CCALLBACK respectively.

	* gsignal.[hc]: cleanups.
	(signal_id_lookup): after walking the anchestry, try interfaces as well.
	(g_signal_new): new function to create signals from varargs type list.
	(g_signal_connect_closure): closure connection variant that works from
	signal name+detail.
	(g_signal_connect_data): c handler connection variant that works from
	signal name+detail.
	(g_signal_emit_valist): emit signal for an instance with paraneters
	collected from a va_list.
	(g_signal_emit): emit signal, taking parameters from varargs list.
	(g_signal_emit_by_name): same as g_signal_emit, working from
	signal name+detail.
	(signal_emit_R): return whether return_value needs to be altered.

	* gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all
	the points that need to reflect the upcoming rename.
	melt g_type_conforms_to() functionality into g_type_is_a(), as that
	is what we really want (liskov substitution principle).
	assorted changes to other files due to conforms_to->is_a.

	* gvalue.[hc]: implemented g_value_set_instance() that sets a value
	from an instantiatable type via the value_table's collect_value()
	function (based on an idea from James Henstridge <james@daa.com.au>).
	cleanups/fixes.

	* gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.

Tue Oct 24 22:09:14 2000  Tim Janik  <timj@gtk.org>

        * glib-object.h: added newly added gobject/ headers.

        * gmesage.c: print g_message() output to stderr instead of stdout.

Wed Oct 25 20:27:02 2000  Tim Janik  <timj@gtk.org>

        * gtype.c (g_type_free_instance): for the moment, freeing object
        structures will fill their memory portion with 0xAA. there's a
        FIXME there, remove this line at a later point.

Tue Oct 24 23:10:26 2000  Tim Janik  <timj@gtk.org>

        * glib-genmarshal.1:
        * glib-genmarshal.c: added publically installed marshaller generator.

        * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
        interface VTable from instances.

        * gobject.[hc]: new functions for closure maintenance:
        (g_object_watch_closure): maintain validity of the object and
        the closure for objects that are used as data part of a closure.
        (g_cclosure_new_object): convenience function to create C closures
        that have an object as data argument.
        (g_closure_new_object): convenience function to create closures
        that have an object as data argument.

        * gclosure.[hc]: implementation of GClosure mechanism.
        a closure is basically an encapsulation of a callback function
        and its environment. ideally, most places supporting callback
        functions will simply take a GClosure* pointer and thus unify
        callback environments wrg destroy notification etc.
        GClosure provides destroy notifiers for arbitrary data pointers,
        reference counting, invalidation notification (it can be invalidated
        which is merely a deactivate state) and a marshallinbg abstraction.
        GCClosure is also provided in these files, they present a specialized
        GClosure implementation for C language callbacks.

        * genum.c: macro cleanups.

        * gboxed.[hc]: new files, for boxed type abstraction.
        (g_boxed_copy): copy a boxed structure
        (g_boxed_free): free a boxed structure
        (g_value_set_boxed):
        (g_value_get_boxed): standard GValue functions for boxed types
        (g_boxed_type_register_static): convenience function for easy
        introduction of new G_TYPE_BOXED derivatives.

        * gparam.[hc]: introduced g_param_type_register_static(), a short hand
        for creation of new GParamSpec derived types.

        * gtype.[hc]: many fixes, introduced ability to flag individual
        type nodes as ABSTRACT upon registration, added value_peek_pointer()
        to the value table to peek at GValue contents as a pointer for types
        that support this. fixed up GValue checks.

        * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
        to peek at the value contents as pointer.

        * *.[hc]: adaptions to type macro fixes and changes in the type
        registration API.

        * many const corrections over the place.

        * gtype.c (g_type_conforms_to): this function basically behaves like
        and is_a check, except that it _additionally_ features interfaces
        for instantiatable types. enforce this in the second branch as well
        (`type' conforms_to `type') even if `type' is not an interface type.

Fri Oct 20 15:31:04 2000  Tim Janik  <timj@gtk.org>

        * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.

        * gtype.[hc]:
        * gobject.c:
        * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
        suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
        and G_TYPE_POINTER.

Mon Aug 21 04:13:37 2000  Tim Janik  <timj@gtk.org>

        * gbsearcharray.[hc]: long standing needed generic implementation
        of a binary searchable, sorted and dynamically sized array.

Fri Jun 23 17:20:26 2000  Tim Janik  <timj@gtk.org>

        * glib.h: define gstring in terms of gchar*. this typedef reflects
        the type name of the primitive G_TYPE_STRING in the gobject module.

Sat Jun 24 23:03:04 2000  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
        G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
        G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
        added a GTypeValueTable* pointer to GTypeInfo structure for types
        to implement GValue handling functions.
        GTypeValueTable contains the following members:
          value_init(): initialize a GValue structure.
          value_free(): free GValue structure contents (optional).
          value_copy(): copy one GValue contents to another GValue structure of
          collect_type: varargs collection type for the first variable argument
          to be collected by collect_value().
          collect_value(): variable arguments collection function (optional).
          lcopy_type: varargs collection type for the first variable argument
          to be location copyied by lcopy_value().
          lcopy_value(): variable arguments location copy function (optional).
        g_type_value_table_peek(): new function to retrive the GTypeValueTable*
        for a type node. ValueTables get inherited from parent types, unless
        overridden through the GTypeInfo structure. internally, GTypeValueTable
        support means an added overhead of one pointer per static or used
        dynamic type node.
        g_type_add_class_cache_func(): provide a cache_func/data pair to be
        called  prior to a type nodes last_unref() function, this can be used
        to prevent premature class destruction. multiple installed cache_func()
        will be chained upon last_unref() untill one of them returns TRUE.
        the cache_func()s have to check the type id passed in to figure whether
        they actually wants to cache the class of this type (since any types are
        routed through the cache_func() chain).
        g_type_remove_class_cache_func(): remove a previously installed
        cache_func/data pair. the cache maintained by this function has to be
        clear when calling g_type_remove_class_cache_func() to avoid leaks.
        g_type_class_unref_uncached(): class unref function for cache_func()
        implementations, unreferences a class omitting the cache chain (and
        therefore unref->cache->unref->... loops).

        * gvaluetypes.[hc]: provide the value setters/getters for the primitive
        fundamental types boolean, char, uchar, int, uint, long, ulong, float,
        double and string.

        * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
        GTypeValueTable is provided for this type.
        removed g_value_init_default(), g_value_validate(), g_value_defaults(),
        g_value_set_default() and g_values_cmp() as these are supplied by the
        GParamSpec API now.
        moved g_values_exchange() into the "implementation details" section,
        since it just provides the underlying functionality for
        g_value_convert().

        * gvaluecollector.h: renamed the varargs value container from
        GParamCValue to GTypeCValue as the value collection methods are
        supplied by the type system now.
        G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
        G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
        GParamSpec structure now.

        * genums.h: macros cleanups/fixes.

        * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
        and assorted g_value_{s|g}et_{enum|flags}() implementations.

        * gobject.[hc]:
        provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
        and g_value_{s|g}et_object().

        * gparam.[hc]: reduced class to value_set_default(),
        value_validate() and values_cmp(). also parameters now need to fill
        in a GType value_type; field to indicate the GValue type they
        are handling. provide g_param_value_set_default(),
        g_param_value_defaults(), g_param_value_validate() and
        g_param_values_cmp().

        * gparamspecs.[hc]: got rid of the g_value_* functions and
        the G_IS_VALUE_* macros. adapted param spec implementations
        according to the GParamSpecClass changes.
